curl -fsSL "https://raw.githubusercontent.com/Dicklesworthstone/beads_viewer/main/install.sh?$(date +%s)" | bashbv is a high-performance Terminal User Interface (TUI) for browsing and managing tasks in projects that use the Beads issue tracking system.
Why you'd care:
- Speed: Browse thousands of issues instantly with zero network latency.
- Focus: Stay in your terminal and use Vim-style keys (
j/k) to navigate. - Intelligence: It visualizes your project as a dependency graph, automatically highlighting bottlenecks, cycles, and critical paths that traditional list-based trackers miss.
- AI-Ready: It provides structured, pre-computed insights for AI coding agents, acting as a "brain" for your project's task management.
At its heart, bv is about viewing your work nicely.
No web page loads, no heavy clients. bv starts instantly and lets you fly through your issue backlog using standard Vim keys (j/k).
- Split-View Dashboard: On wider screens, see your list on the left and full details on the right.
- Markdown Rendering: Issue descriptions, comments, and notes are beautifully rendered with syntax highlighting, headers, and lists.
- Instant Filtering: Zero-latency filtering. Press
ofor Open,cfor Closed, orrfor Ready (unblocked) tasks. - Live Reload: Watches
.beads/beads.jsonland refreshes lists, details, and insights automatically when the file changes—no restart needed.
Don't just read the title. bv gives you the full picture:
- Comments & History: Scroll through the full conversation history of any task.
- Metadata: Instantly see Assignees, Labels, Priority badges, and creation dates.
- Search: Powerful fuzzy search (
/) finds issues by ID, title, or content instantly.
- Kanban Board: Press
bto switch to a columnar view (Open, In Progress, Blocked, Closed) to visualize flow. - Visual Graph: Press
gto explore the dependency tree visually. - Insights: Press
ito see graph metrics and bottlenecks. - History View: Press
hto see the timeline of changes, correlating git commits with bead modifications. On wider terminals, enjoy a responsive three-pane layout showing commits, affected beads, and details. - Ultra-Wide Mode: On large monitors, the list expands to show extra columns like sparklines and label tags.
- Export: Press
Eto export all issues to a timestamped Markdown file with Mermaid diagrams. - Graph Export (CLI):
bv --robot-graphoutputs the dependency graph as JSON, DOT (Graphviz), or Mermaid format. Use--graph-format=dotfor rendering with Graphviz, or--graph-root=ID --graph-depth=3to extract focused subgraphs. - Copy: Press
Cto copy the selected issue as formatted Markdown to your clipboard. - Edit: Press
Oto open the.beads/beads.jsonlfile in your preferred GUI editor. - Time-Travel: Press
tto compare against any git revision, orTfor quick HEAD~5 comparison. Combined with History view (h), you can navigate to any commit and see exactly what changed.
Configure pre- and post-export hooks in .bv/hooks.yaml to run validations, notifications, or uploads. Defaults: pre-export hooks fail fast on errors (on_error: fail), post-export hooks log and continue (on_error: continue). Empty commands are ignored with a warning for safety. Hook env includes BV_EXPORT_PATH, BV_EXPORT_FORMAT, BV_ISSUE_COUNT, BV_TIMESTAMP, plus any custom env entries.
### Using bv as an AI sidecar
bv is a graph-aware triage engine for Beads projects (.beads/beads.jsonl). Instead of parsing JSONL or hallucinating graph traversal, use robot flags for deterministic, dependency-aware outputs with precomputed metrics (PageRank, betweenness, critical path, cycles, HITS, eigenvector, k-core).
**Scope boundary:** bv handles *what to work on* (triage, priority, planning). For agent-to-agent coordination (messaging, work claiming, file reservations), use [MCP Agent Mail](https://github.com/Dicklesworthstone/mcp_agent_mail).
**⚠️ CRITICAL: Use ONLY `--robot-*` flags. Bare `bv` launches an interactive TUI that blocks your session.**
#### The Workflow: Start With Triage
**`bv --robot-triage` is your single entry point.** It returns everything you need in one call:
- `quick_ref`: at-a-glance counts + top 3 picks
- `recommendations`: ranked actionable items with scores, reasons, unblock info
- `quick_wins`: low-effort high-impact items
- `blockers_to_clear`: items that unblock the most downstream work
- `project_health`: status/type/priority distributions, graph metrics
- `commands`: copy-paste shell commands for next steps
bv --robot-triage # THE MEGA-COMMAND: start here
bv --robot-next # Minimal: just the single top pick + claim command
#### Other Commands
**Planning:**
| Command | Returns |
|---------|---------|
| `--robot-plan` | Parallel execution tracks with `unblocks` lists |
| `--robot-priority` | Priority misalignment detection with confidence |
**Graph Analysis:**
| Command | Returns |
|---------|---------|
| `--robot-insights` | Full metrics: PageRank, betweenness, HITS (hubs/authorities), eigenvector, critical path, cycles, k-core, articulation points, slack |
| `--robot-label-health` | Per-label health: `health_level` (healthy\|warning\|critical), `velocity_score`, `staleness`, `blocked_count` |
| `--robot-label-flow` | Cross-label dependency: `flow_matrix`, `dependencies`, `bottleneck_labels` |
| `--robot-label-attention [--attention-limit=N]` | Attention-ranked labels by: (pagerank × staleness × block_impact) / velocity |
**History & Change Tracking:**
| Command | Returns |
|---------|---------|
| `--robot-history` | Bead-to-commit correlations: `stats`, `histories` (per-bead events/commits/milestones), `commit_index` |
| `--robot-diff --diff-since <ref>` | Changes since ref: new/closed/modified issues, cycles introduced/resolved |
**Other Commands:**
| Command | Returns |
|---------|---------|
| `--robot-burndown <sprint>` | Sprint burndown, scope changes, at-risk items |
| `--robot-forecast <id\|all>` | ETA predictions with dependency-aware scheduling |
| `--robot-alerts` | Stale issues, blocking cascades, priority mismatches |
| `--robot-suggest` | Hygiene: duplicates, missing deps, label suggestions, cycle breaks |
| `--robot-graph [--graph-format=json\|dot\|mermaid]` | Dependency graph export |
| `--export-graph <file.html>` | Self-contained interactive HTML visualization |
#### Scoping & Filtering
bv --robot-plan --label backend # Scope to label's subgraph
bv --robot-insights --as-of HEAD~30 # Historical point-in-time
bv --recipe actionable --robot-plan # Pre-filter: ready to work (no blockers)
bv --recipe high-impact --robot-triage # Pre-filter: top PageRank scores
bv --robot-triage --robot-triage-by-track # Group by parallel work streams
bv --robot-triage --robot-triage-by-label # Group by domain
#### Understanding Robot Output
**All robot JSON includes:**
- `data_hash` — Fingerprint of source beads.jsonl (verify consistency across calls)
- `status` — Per-metric state: `computed|approx|timeout|skipped` + elapsed ms
- `as_of` / `as_of_commit` — Present when using `--as-of`; contains ref and resolved SHA
**Two-phase analysis:**
- **Phase 1 (instant):** degree, topo sort, density — always available immediately
- **Phase 2 (async, 500ms timeout):** PageRank, betweenness, HITS, eigenvector, cycles — check `status` flags
**For large graphs (>500 nodes):** Some metrics may be approximated or skipped. Always check `status`.
#### jq Quick Reference
bv --robot-triage | jq '.quick_ref' # At-a-glance summary
bv --robot-triage | jq '.recommendations[0]' # Top recommendation
bv --robot-plan | jq '.plan.summary.highest_impact' # Best unblock target
bv --robot-insights | jq '.status' # Check metric readiness
bv --robot-insights | jq '.Cycles' # Circular deps (must fix!)
bv --robot-label-health | jq '.results.labels[] | select(.health_level == "critical")'
**Performance:** Phase 1 instant, Phase 2 async (500ms timeout). Prefer `--robot-plan` over `--robot-insights` when speed matters. Results cached by data hash.
Use bv instead of parsing beads.jsonl—it computes PageRank, critical paths, cycles, and parallel tracks deterministically.
bv can automatically add the above instructions to your project's agent file:
- On first run, bv checks for AGENTS.md (or similar files) and offers to inject the blurb if not present
- Choose "Yes" to add the instructions, "No" to skip, or "Don't ask again" to remember your preference
- Preferences are stored per-project in
~/.config/bv/agent-prompts/
Supported Files (checked in order):
AGENTS.md(preferred)CLAUDE.mdagents.mdclaude.md
Manual Control:
bd agents --show # Display current blurb content
bd agents --check # Check if blurb is present in agent file
bd agents --add # Add blurb to agent file
bd agents --remove # Remove blurb from agent file
bd agents --clear-preference # Reset the "don't ask again" preferenceVersion Tracking:
The blurb uses HTML comment markers for version tracking:
<!-- bv-agent-instructions-v1 -->
... content ...
<!-- end-bv-agent-instructions -->
When a new version of the blurb is released, bv can detect the outdated version and offer to update it.
bv treats your project as a Directed Acyclic Graph (DAG), not just a list. This allows it to derive insights about what is truly important.

bv computes 9 graph-theoretic metrics to surface hidden project dynamics:
| # | Metric | What It Measures | Key Insight |
|---|---|---|---|
| 1 | PageRank | Recursive dependency importance | Foundational blockers |
| 2 | Betweenness | Shortest-path traffic | Bottlenecks & bridges |
| 3 | HITS | Hub/Authority duality | Epics vs. utilities |
| 4 | Critical Path | Longest dependency chain | Keystones with zero slack |
| 5 | Eigenvector | Influence via neighbors | Strategic dependencies |
| 6 | Degree | Direct connection counts | Immediate blockers/blocked |
| 7 | Density | Edge-to-node ratio | Project coupling health |
| 8 | Cycles | Circular dependencies | Structural errors |
| 9 | Topo Sort | Valid execution order | Work queue foundation |
The Math: Originally designed to rank web pages by "importance" based on incoming links, PageRank models a "random surfer" walking the graph. In our dependency graph (u → v implies u depends on v), we treat dependencies as "votes" of importance. $$ PR(v) = \frac{1-d}{N} + d \sum_{u \in M(v)} \frac{PR(u)}{L(u)} $$
The Intuition: If many tasks depend on Task A, or if a single very important Task B depends on Task A, then Task A implicitly becomes "heavy." A random walker following dependency links will frequently get stuck at Task A.
Pragmatic Meaning: Foundational Blocks. High PageRank tasks are the bedrock of your project. They are rarely "features" in the user-facing sense; they are often schemas, core libraries, or architectural decisions. Breaking them breaks the graph.
The Math: Defined as the fraction of all shortest paths in the network that pass through a given node
The Intuition: Imagine information (or progress) flowing from every task to every other task along the most efficient route. "Bridge nodes" that connect otherwise isolated clusters (e.g., the Frontend cluster and the Backend cluster) will see a massive amount of traffic.
Pragmatic Meaning: Gatekeepers & Bottlenecks. A task with high Betweenness is a choke point. It might be an API contract that both the mobile app and the server team are waiting on. If this task is delayed, it doesn't just block one thread; it prevents entire sub-teams from synchronizing.
The Math: An iterative algorithm that defines two scores for every node:
- Authority: The sum of Hub scores of nodes pointing to it.
- Hub: The sum of Authority scores of nodes it points to.
The Intuition: This models a "mutually reinforcing" relationship. Good libraries (Authorities) are used by many applications. Good applications (Hubs) use many good libraries.
Pragmatic Meaning: Epics vs. Infrastructure.
- High Hub Score: These are your Epics or Product Features. They aggregate many dependencies to deliver value.
- High Authority Score: These are your Utilities. They provide value to many consumers.
The Math: In a DAG, the longest path represents the minimum time required to complete the project (assuming infinite parallelism). bv computes this recursively:
The Intuition: If you hold the graph by its "leaf" nodes (tasks with no dependencies) and let it dangle, the tasks at the very top that support the longest chains are carrying the most weight.
Pragmatic Meaning: Keystones. A Keystone task is one where any delay translates 1:1 into a delay for the final project delivery. These tasks have zero "slack."
The Math: Eigenvector centrality measures a node's influence by considering not just its connections, but the importance of those connections. A node with few but highly influential neighbors can score higher than a node with many unimportant neighbors.
Where
The Intuition: It's not just how many connections you have, but who you're connected to. Being depended on by a critical task makes you more important than being depended on by many trivial tasks.
Pragmatic Meaning: Strategic Dependencies. High Eigenvector tasks are connected to the "power players" in your graph. They may not have many direct dependents, but their dependents are themselves critical.
The Math: The simplest centrality measure—just count the edges.
The Intuition:
- In-Degree: How many tasks depend on me? (I am a blocker)
- Out-Degree: How many tasks do I depend on? (I am blocked)
Pragmatic Meaning: Immediate Impact.
- High In-Degree: This task is a direct blocker for many others. Completing it immediately unblocks work.
- High Out-Degree: This task has many prerequisites. It's likely to be blocked and should be scheduled later in the execution plan.
The Math: Density measures how "connected" the graph is relative to its maximum possible connections.
Where
The Intuition: A density of 0.0 means no dependencies exist (isolated tasks). A density approaching 1.0 means everything depends on everything (pathological complexity).
Pragmatic Meaning: Project Health Indicator.
- Low Density (< 0.05): Healthy. Tasks are relatively independent and can be parallelized.
- Medium Density (0.05 - 0.15): Normal. Reasonable interconnection reflecting real-world dependencies.
- High Density (> 0.15): Warning. Overly coupled project. Consider breaking into smaller modules.
The Math: A cycle in a directed graph is a path v₁ → v₂ → ⋯ → vₖ → v₁ where the start and end nodes are identical. bv uses Tarjan's algorithm variant via topo.DirectedCyclesIn to enumerate all elementary cycles.
The Intuition: If A depends on B, and B depends on A, neither can ever be completed. This is a logical impossibility that must be resolved.
Pragmatic Meaning: Structural Errors. Cycles are bugs in your project plan, not just warnings. They indicate:
- Misclassified dependencies (A doesn't really block B, or vice versa)
- Missing intermediate tasks (A and B both depend on an unstated C)
- Scope confusion (A and B should be merged into a single task)
The Math: A topological ordering of a DAG is a linear sequence of all vertices such that for every edge u → v, vertex u appears before v in the sequence. Only acyclic graphs have valid topological orderings.
The Intuition: If you must complete tasks in dependency order, topological sort gives you a valid order (there may be many).
Pragmatic Meaning: Work Queue. The topological order is the foundation of bv's execution planning. Combined with priority weights, it generates the "what to work on next" recommendations that power --robot-plan.
bv bridges the gap between raw data and AI agents. Agents struggle with graph algorithms; bv solves this by acting as a deterministic "sidecar" that offloads the cognitive burden of graph traversal.

end
The primary design goal of the Robot Protocol is Cognitive Offloading. Large Language Models (LLMs) are probabilistic engines; they are excellent at semantic reasoning (coding, writing) but notoriously unreliable at algorithmic graph traversal (finding cycles, computing shortest paths). The two-phase analyzer returns degree/topo/density immediately and completes PageRank/Betweenness/HITS/Eigenvector/Critical Path/Cycles asynchronously with size-aware timeouts and hashed caching, so repeat robot calls stay fast when the graph hasn’t changed.
If you feed an Agent raw beads.jsonl data, you are forcing the Agent to:
- Parse thousands of lines of JSON.
- Reconstruct the dependency graph in its context window.
- "Hallucinate" a path traversal or cycle check.
bv solves this by providing a deterministic graph engine sidecar.
Using beads directly gives an agent data. Using bv --robot-insights gives an agent intelligence.
| Capability | Raw Beads (JSONL) | bv Robot Mode |
|---|---|---|
| Query | "List all issues." | "List the top 5 bottlenecks blocking the release." |
| Context Cost | High (Linear with issue count). | Low (Fixed summary struct). |
| Graph Logic | Agent must infer/compute. | Pre-computed (PageRank/Brandes). |
| Safety | Agent might miss a cycle. | Cycles explicitly flagged. |
Agents typically use bv in three phases:
-
Triage & Orientation: Before starting a session, the agent runs
bv --robot-insights. It receives a lightweight JSON summary of the project's structural health. It immediately knows:- "I should not work on Task C yet because it depends on Task B, which is a Bottleneck."
- "The graph has a cycle (A->B->A); I must fix this structural error before adding new features."
-
Impact Analysis: When asked to "refactor the login module," the agent checks the PageRank and Impact Scores of the relevant beads. If the scores are high, the agent knows this is a high-risk change with many downstream dependents, prompting it to run more comprehensive tests.
-
Execution Planning: Instead of guessing the order of operations, the agent uses
bv's topological sort to generate a strictly linearized plan.
JSON Output Schema (--robot-insights):
The output is designed to be strictly typed and easily parseable by tools like jq or standard JSON libraries.

bv doesn't just dump text; it calculates geometry on every render cycle.
- Dynamic Resizing: The
View()function inspects the current terminal width (msg.Width) on every frame. - Breakpoint Logic:
< 100 cols: Mobile Mode. List takes 100% width.> 100 cols: Split Mode. List takes 40%, Details take 60%.> 140 cols: Ultra-Wide. List injects extra columns (Sparklines, Labels) that are normally hidden.
- Padding Awareness: The layout engine explicitly accounts for borders (2 chars) and padding (2 chars) to prevent "off-by-one" wrapping errors that plague many TUIs.
Rendering 10,000 issues would choke a naive terminal app. bv implements Viewport Virtualization:
- Windowing: We only render the slice of rows currently visible in the terminal window.
- Pre-Computation: Graph metrics (PageRank, etc.) are computed once at startup in a separate goroutine, not on every frame.
- Detail Caching: The Markdown renderer is instantiated lazily and reused, avoiding expensive regex recompilation.
We built a custom 2D ASCII/Unicode rendering engine from scratch to visualize the dependency graph.
- Canvas Abstraction: A 2D grid of
runecells andstylepointers allows us to draw "pixels" in the terminal. - Manhattan Routing: Edges are drawn using orthogonal lines with proper Unicode corner characters (
╭,─,╮,│,╰,╯) to minimize visual noise. - Topological Layering: Nodes are arranged in layers based on their "Impact Depth," ensuring that dependencies always flow downwards.
We use Lipgloss to enforce a strict design system.
- Semantic Colors: Colors are defined semantically (
Theme.Blocked,Theme.Open) rather than hardcoded hex values. This allowsbvto switch between "Dracula" (Dark) and "Light" modes seamlessly. - Status Indicators: We use Nerd Font glyphs (
🐛,✨,🔥) paired with color coding to convey status instantly without reading text.
In dense information environments like the terminal, text is expensive. bv employs high-density data visualization techniques (pkg/ui/visuals.go) inspired by Edward Tufte to convey complex metrics in minimal space.
When viewing the list in Ultra-Wide mode, bv renders a "Graph Score" column using Unicode block characters ( , ▂, ▃, ▄, ▅, ▆, ▇, █).
- The Math:
RenderSparkline(val, width)normalizes a float value (0.0 - 1.0) against the available character width. It calculates the precise block height for each character cell to create a continuous bar chart effect. - The Utility: This allows you to scan a list of 50 issues and instantly spot the "spikes" in complexity or centrality without reading a single number.
We don't just use random colors. pkg/ui/visuals.go implements a perceptually uniform color ramp (GetHeatmapColor) that maps metric intensity to a gradient:
0.0 - 0.2: Low (Gray/Dim)0.2 - 0.5: Mid (Blue/Cool)0.5 - 0.8: High (Purple/Warm)0.8 - 1.0: Peak (Pink/Hot) This visual encoding is applied to badges in the Insights Dashboard, allowing you to differentiate between "somewhat important" and "critically urgent" tasks at a glance.
In a project with thousands of issues, you cannot afford to wait for a backend query. bv implements a composite, in-memory fuzzy search that feels instantaneous.
Instead of searching fields individually (which requires complex UI controls), bv flattens every issue into a single searchable "vector" at load time.
The FilterValue() method constructs a composite string containing:
- Core Identity: ID (
"CORE-123") and Title ("Fix login race condition") - Metadata: Status (
"open"), Type ("bug"), Priority - Context: Assignee (
"@steve") and Labels ("frontend, v1.0")
When you press /, the search engine performs a fuzzy subsequence match against this composite vector.
- Example: Typing
"log fix"successfully matches"Fix login race condition". - Example: Typing
"steve bug"finds bugs assigned to Steve. - Example: Typing
"open v1.0"filters for open items in the v1.0 release.
- Zero Allocation: The search index is built once during the initial load (
loader.LoadIssues). - Client-Side Filtering: Filtering happens entirely within the render loop. There is no database latency, no network round-trip, and no "loading" spinner.
- Stable Sort: Search results maintain the topological and priority sorting of the main list, ensuring that even filtered views reflect the project's true priorities.
A common question is: "How do you render complex diagrams in a text-only terminal?"
bv approaches this problem in two ways:
For the interactive TUI, we built a specialized ASCII/Unicode Graph Engine (pkg/ui/graph.go) that replicates the core value of a Mermaid flowchart without requiring graphical protocol support (like Sixel).
- Topological Layering: Nodes are automatically sorted by their dependency depth.
- Orthogonal Routing: Connections use box-drawing characters (
│,─,╭,╯) to draw clean, right-angled paths that avoid crossing through node text. - Adaptive Canvas: The virtual canvas expands infinitely, but the viewport (
pkg/ui/viewport.go) clips rendering to exactly what fits on your screen, panning smoothly withh/j/k/l.
For external reporting, bv includes a robust Mermaid Generator (pkg/export/markdown.go).
- Sanitization: It automatically escapes unsafe characters in issue titles to prevent syntax errors in the Mermaid parser.
- Collision-Proof IDs: When sanitization would collide (e.g., symbol-only IDs), nodes get a stable hash suffix so edges never merge or disappear.
- Class-Based Styling: Nodes are assigned CSS classes (
classDef open,classDef blocked) based on their status, so the resulting diagram visually matches the TUI's color scheme when rendered on GitHub or GitLab. - Semantic Edges: Blockers are rendered with thick arrows (
==>), while loose relations use dashed lines (-.->), encoding the severity of the link into the visual syntax.

}For deep exploration of complex dependency structures, bv generates self-contained HTML visualizations powered by a force-directed graph engine. Unlike static exports, these are fully interactive—pan, zoom, filter, and drill into individual beads without any server or dependencies.
# Generate interactive HTML graph
bv --export-graph graph.html # Export to specific file
bv --export-graph # Auto-generate timestamped filename
bv --export-graph --graph-title "Q4 Sprint" # Custom title
bv --export-graph --graph-include-closed # Include closed issuesTraditional list-based views show tasks in isolation. The interactive graph reveals the hidden structure of your project:
- Dependency Chains: See at a glance which tasks are blocking others, and trace critical paths through your backlog
- Bottleneck Detection: Nodes sized by PageRank/betweenness instantly reveal which items have outsized impact
- Cluster Discovery: Force-directed layout naturally groups related work, exposing team boundaries or feature clusters
- Context Switching: Hover over any node to see full details—description, design notes, acceptance criteria—without leaving the visualization
Each HTML file is completely self-contained (typically 400KB-1MB depending on project size):
| Component | Description |
|---|---|
| Full Bead Data | Title, description, design, acceptance criteria, notes, labels, timestamps |
| Graph Metrics | PageRank, betweenness, critical path score, slack, hub/authority scores |
| Triage Analysis | Complete triage recommendations with scores and reasons |
| Git Correlation | Commit history linked to each bead (when available) |
| Dependency Map | Full blocked-by/blocks relationships with visual edges |
The visualization provides a rich, keyboard-driven interface:

bv isn't just for personal browsing; it's a communication tool. The --export-md flag generates a Management-Ready Status Report that converts your repo state into a polished document suitable for stakeholders.
The exporter (pkg/export/markdown.go) constructs a document that bridges human readability and visual data:
- Summary at a Glance: Top-level statistics (Total, Open, Blocked, Closed) give immediate health context.
- Embedded Graph: It injects the full dependency graph as a Mermaid diagram right into the document. On platforms like GitHub or GitLab, this renders as an interactive chart.
- Anchor Navigation: A generated Table of Contents uses URL-friendly slugs (
#core-123-refactor-login) to link directly to specific issue details, allowing readers to jump between the high-level graph and low-level specs.
We don't just dump JSON values. The exporter applies specific formatting rules to ensure the report looks professional:
- Metadata Tables: Key fields (Assignee, Priority, Status) are aligned in GFM (GitHub Flavored Markdown) tables with emoji indicators.
- Conversation threading: Comments are rendered as blockquotes (
>) with relative timestamps, preserving the flow of discussion distinct from the technical spec. - Intelligent Sorting: The report doesn't list issues ID-sequentially. It applies the same priority logic as the TUI: Open Critical issues appear first, ensuring the reader focuses on what matters now.
One of bv's most powerful capabilities is Time-Travel—the ability to compare your project's state across any two points in git history. This transforms bv from a "viewer" into a progress tracking and regression detection system.
bv captures the complete state of your project at any moment:
graph LR
%%{init: {'theme': 'base', 'themeVariables': { 'primaryColor': '#e8f5e9', 'primaryTextColor': '#2e7d32', 'primaryBorderColor': '#81c784', 'lineColor': '#90a4ae'}}}%%

The SnapshotDiff captures every meaningful change:
| Category | Tracked Changes |

| Issues | New, Closed, Reopened, Removed, Modified |
| Fields | Title, Status, Priority, Tags, Dependencies |
| Graph | New Cycles, Resolved Cycles |
| Metrics | Δ PageRank, Δ Betweenness, Δ Density |
The GitLoader enables loading issues from any git revision:
loader := NewGitLoader("/path/to/repo")
// Load from various references
current, _ := loader.LoadAt("HEAD")
lastWeek, _ := loader.LoadAt("HEAD~7")
release, _ := loader.LoadAt("v1.0.0")
byDate, _ := loader.LoadAt("main@{2024-01-15}")Cache Architecture:
- Revisions are resolved to commit SHAs for stable caching
- Thread-safe
sync.RWMutexprotects concurrent access - 5-minute TTL prevents stale data while avoiding redundant git calls
- Sprint Retrospectives: "How many issues did we close this sprint?"
- Regression Detection: "Did we accidentally reintroduce a dependency cycle?"
- Trend Analysis: "Is our graph density increasing? Are we creating too many dependencies?"
- Release Notes: "Generate a diff of all changes between v1.0 and v2.0"
Instead of memorizing CLI flags or repeatedly setting filters, bv supports Recipes—YAML-based view configurations that can be saved, shared, and version-controlled.

bv --recipe .beads/recipes/sprint-review.yamlTraditional issue trackers sort by a single dimension—usually priority. bv computes a multi-factor Impact Score that blends graph-theoretic metrics with temporal and priority signals.
| Component | Weight | What It Measures |
|---|---|---|
| PageRank | 30% | Recursive dependency importance |
| Betweenness | 30% | Bottleneck/bridge position |
| BlockerRatio | 20% | Direct dependents (In-Degree) |
| Staleness | 10% | Days since last update (aging) |
| PriorityBoost | 10% | Human-assigned priority |
- 60% Graph Metrics: The structure of dependencies is the primary driver of true importance.
- 20% Blocker Ratio: Direct dependents matter for immediate unblocking.
- 10% Staleness: Old issues deserve attention; they may be forgotten blockers.
- 10% Priority: Human judgment is valuable but can be outdated or politically biased.

"betweenness": 0.25,
"blocker_ratio": 0.18,
"staleness": 0.07,
"priority_boost": 0.08
}
}bv generates actionable recommendations when the computed impact score diverges significantly from the human-assigned priority:
⚠️ CORE-123 has Impact Score 0.85 but Priority P3. Reason: High PageRank (foundational dependency) + High Betweenness (bottleneck) Recommendation: Consider escalating to P1.
Press p in the list view to toggle Priority Hints—inline visual indicators showing which issues have misaligned priorities:
┌──────────────────────────────────────────────────────────────┐
│ OPEN CORE-123 ⬆ Database schema migration P3 🟢 │
│ OPEN UI-456 Login page styling P2 🟢 │
│ BLOCKED API-789 ⬇ Legacy endpoint wrapper P1 🔴 │
└──────────────────────────────────────────────────────────────┘
⬆ = Impact suggests higher priority (red arrow)
⬇ = Impact suggests lower priority (teal arrow)
This provides at-a-glance feedback on whether your priority assignments match the computed graph importance.
When you ask "What should I work on next?", bv doesn't just pick the highest-priority item. It generates a complete execution plan that respects dependencies and identifies opportunities for parallel work.
The planner uses Union-Find to identify connected components in the dependency graph, grouping related issues into independent "tracks" that can be worked on concurrently.

}- Identify Actionable Issues: Filter to non-closed issues with no open blockers.
- Compute Unblocks: For each actionable issue, calculate what becomes unblocked if it's completed.
- Find Connected Components: Use Union-Find to group issues by their dependency relationships.
- Build Tracks: Create parallel tracks from each component, sorted by priority within each track.
- Compute Summary: Identify the single highest-impact issue (most downstream unblocks).
- Deterministic: Same input always produces same plan (no LLM hallucination).
- Parallelism-Aware: Multiple agents can grab different tracks without conflicts.
- Impact-Ranked: The
highest_impactfield tells agents exactly where to start.
The Insights Dashboard (i) transforms abstract graph metrics into an interactive exploration interface. Instead of just showing numbers, it lets you drill into why a bead scores high and what that means for your project.

Press s to cycle through five distinct sort modes, giving you instant control over how issues are organized. The current sort mode is displayed in the status bar.
| Mode | Key Display | Ordering Logic | Use Case |
|---|---|---|---|
| Default | Default |
Priority (asc) → Created (desc) | Standard priority-driven workflow |
| Created ↑ | Created ↑ |
Creation date ascending (oldest first) | Audit: find long-standing issues |
| Created ↓ | Created ↓ |
Creation date descending (newest first) | Review: see recently created work |
| Priority | Priority |
Priority only (P0 → P4) | Pure priority triage |
| Updated | Updated |
Last update descending (newest first) | Activity tracking: see active issues |
The sort system uses a stable secondary sort to ensure deterministic ordering. When primary sort values are equal, issues fall back to ID ordering for consistency across sessions. This prevents the "shuffling list" problem where equal-priority items randomly reorder.

}Beyond simple bead-to-commit correlation, bv provides deep analysis of how beads relate to each other through shared code changes. This helps identify hidden dependencies, find related work, and understand the true impact of changes.
The Impact Network visualizes implicit relationships between beads based on:

Find all beads that have touched a specific file using --robot-file-beads:
bv --robot-file-beads pkg/ui/board.goReturns beads sorted by recency with commit details:
{
"file_path": "pkg/ui/board.go",
"total_beads": 21,
"open_beads": [],
"closed_beads": [
{
"bead_id": "bv-v67w",

}
]
}Use cases:
- Code ownership: "Who has worked on this file recently?"
- Impact analysis: "What work items are affected by this file?"
- Bug investigation: "What changes might have introduced this regression?"
Find commits that should be linked to beads but aren't using --robot-orphans:

}
]
}
]
}Use cases:
- Hygiene: Find commits that slipped through without proper linking
- Audit: Ensure all code changes are tracked to work items
- Correlation improvement: Train the system by confirming/rejecting suggestions
For any bead, bv can find related work across four dimensions:
| Relation Type | How Detected | Example |
|---|---|---|
| File Overlap | Both beads modify same source files | "BV-123 and BV-456 both touch session.go" |
| Commit Overlap | Both beads referenced in same commit | "BV-123 and BV-456 fixed in commit abc123" |
| Dependency Cluster | Both in same tightly-connected subgraph | "BV-123 is in the Auth cluster with BV-456" |
| Concurrent | Active during the same time window | "BV-123 and BV-456 both worked on last week" |
Each relation includes a relevance score (0-100) indicating strength.

bv --robot-orphansThe --robot-causality command reveals why a bead took as long as it did by reconstructing its timeline of events:
| Event Type | Description |
|---|---|
created |
Bead was opened |
claimed |
Work started (status → in_progress) |
commit |
Code commit linked to bead |
blocked |
Bead became blocked by another bead |
unblocked |
Blocking dependency was resolved |
closed |
Bead was completed |
reopened |
Bead was reopened after closure |
Insights provided:
- Blocked percentage: How much time was spent waiting on dependencies
- Critical path: The chain of events determining minimum completion time
- Longest gap: Identifies stalled periods needing investigation
- Recommendations: Actionable suggestions (e.g., "Consider breaking into smaller beads")

The burndown chart implements a scope-aware algorithm that tracks not just completion velocity but also scope changes:
- Ideal Burn Rate:
Total Beads / Sprint Duration - Actual Burn Rate:
Closed Beads / Days Elapsed - Scope Events: Added/removed beads create discontinuities in the ideal line
When beads are added mid-sprint, the burndown recalculates the ideal trajectory from that point forward, providing a realistic view of progress rather than a misleading "behind schedule" indicator.
Items are flagged as at-risk based on multiple heuristics:
| Signal | Threshold | Reason |
|---|---|---|
| Blocked Duration | > 2 days | Dependency bottleneck |
| No Activity | > 4 days | Potentially stuck or forgotten |
| High Priority Blocked | P0/P1 blocked | Critical path impediment |
| Dependencies Not Closing | Blockers still open | Cascading delay risk |

bv --robot-plan --label backend # Execution plan for backend domain
bv --robot-priority --label auth # Priority recommendations for auth workThis enables domain isolation: analyze and plan within a bounded context rather than the entire project graph.
The flow matrix reveals how labels depend on each other:

api - 3 2 0
auth 1 - 0 1
ui 4 2 - 0
docs 0 0 0 -
Read as: "api has 3 issues that depend on auth issues." High values indicate coupling between domains; the bottleneck_labels field highlights labels that block the most cross-domain work.

All robot commands support --as-of <ref> for historical analysis. Output includes as_of and as_of_commit metadata fields when specified.
The --as-of flag lets you view project state at any historical point without modifying your working tree. It works with both the interactive TUI and all robot commands.
# View historical state (TUI)
bv --as-of HEAD~10 # 10 commits ago
bv --as-of v1.0.0 # At release tag

--search-weights '{"text":0.4,"pagerank":0.2,"status":0.15,"impact":0.1,"priority":0.1,"recency":0.05}'Semantic search builds a lightweight vector index from a weighted issue document (ID and title repeated, labels and description included). This keeps lookup fast while still behaving like a human-readable search.
Hybrid mode is a two-stage pipeline: it first retrieves the top candidates by semantic similarity, then re-ranks those candidates using graph-aware signals (PageRank, status, impact, priority, recency). That keeps results anchored to your query while surfacing items that matter most in the dependency graph—a good fit for bv’s goal of making the “why this matters” visible.
Short, intent-heavy queries (e.g., “benchmarks”, “oauth”) are treated differently on purpose. bv widens the candidate pool, boosts literal matches, and raises the text weight so quick lookups behave like a precise search. Longer, descriptive queries lean more on graph signals for smart tie‑breaking and prioritization.
Hybrid defaults can be set via:
BV_SEARCH_MODE(text|hybrid)BV_SEARCH_PRESET(default|bug-hunting|sprint-planning|impact-first|text-only)BV_SEARCH_WEIGHTS(JSON string, overrides preset)
In --robot-search JSON, hybrid results include mode, preset, weights, plus per-result text_score and component_scores.

Trust is earned. bv employs a rigorous testing strategy to ensure it can handle the messy reality of real-world repositories.
We don't just test on "happy path" data. The test suite (pkg/loader/synthetic_test.go) generates Synthetic Complex Graphs—large JSONL files with thousands of nodes, intricate dependency cycles, and edge-case UTF-8 characters—to verify that the graph engine and rendering logic never panic under load.
In a git-based workflow, merge conflicts and partial writes happen. The TestLoadIssuesRobustness suite explicitly injects garbage lines and corrupted JSON into the data stream.
- Result:
bvdetects corruption, logs a warning tostderr, and continues loading the valid data. It never crashes the user session due to a single bad line.
For contributors writing tests, see the comprehensive Testing Guide which covers:
- Test philosophy (no mocks, table-driven tests, golden files)
- Using the
testutilpackage for fixture generation - Running tests, coverage, and benchmarks
- E2E test patterns and CI integration
bv includes a proactive, non-intrusive update check to ensure you never miss a feature. We believe tools should maintain themselves without interrupting your flow.
The updater (pkg/updater/updater.go) is architected for silence and safety:
- Non-Blocking Concurrency: The check runs in a detached goroutine with a strict 2-second timeout. It never delays your startup time or UI interactivity.
- Semantic Versioning: It doesn't just match strings. A custom SemVer comparator ensures you are only notified about strictly newer releases, handling complex edge cases like release candidates vs. stable builds.
- Resilience: It gracefully handles network partitions, GitHub API rate limits (403/429), and timeouts by silently failing. You will never see a crash or error log due to an update check.
- Unobtrusive Notification: When an update is found,
bvdoesn't pop a modal. It simply renders a subtle Update Available indicator (⭐) in the footer, letting you choose when to upgrade.
Reliability is key. bv doesn't assume a perfect environment; it actively handles common file system inconsistencies.
The loader (pkg/loader/loader.go) doesn't just blindly open .beads/beads.jsonl. It employs a priority-based discovery algorithm:
- Canonical: Checks for
beads.jsonl. - Legacy: Fallback to
issues.jsonlfor older repos. - Base: Checks
beads.base.jsonl(used bybdin daemon mode). - Validation: It skips temporary files like
*.backupordeletions.jsonlto prevent displaying corrupted state.
The JSONL parser is designed to be Lossy-Tolerant.
- It uses a buffered scanner (
bufio.NewScanner) with a generous 10MB line limit to handle massive description blobs. - Malformed lines (e.g., from a merge conflict) are skipped with a warning rather than crashing the application, ensuring you can still view the readable parts of your project even during a bad git merge.
Traditional issue trackers (Jira, GitHub Issues, Trello) model work as Buckets: "To Do", "In Progress", "Done". This is fine for simple task lists, but it fails at scale because it ignores Structure.
In complex software projects, tasks are not isolated. They are deeply interconnected. A "simple" frontend task might depend on a backend endpoint, which depends on a schema change, which depends on a migration script.
bv adopts a Graph-First philosophy:
- Structure is Reality: The dependency graph is the project. The list view is just a projection of that graph.
- Explicit Blocking: We don't just "relate" tasks; we define strict "blocks". If A blocks B, you literally cannot mark B as "Ready" in
bvuntil A is Closed. - Local-First, Text-Based: Your project data lives in your repo (
.beads/beads.jsonl), not on a remote server. It travels with your code, branches with your git, and merges with your PRs.
bv is engineered for speed. We believe that latency is the enemy of flow.
- Startup Time: < 50ms for typical repos (< 1000 issues).
- Rendering: 60 FPS UI updates using Bubble Tea.
- Virtualization: List views and Markdown renderers are fully windowed.
bvcan handle repositories with 10,000+ issues without UI lag, consuming minimal RAM. - Graph Compute: A two-phase analyzer computes topo/degree/density instantly, then PageRank/Betweenness/HITS/Critical Path/Cycles asynchronously with size-aware timeouts.
- Caching: Repeated analyses reuse hashed results automatically, avoiding recomputation when the bead graph hasn’t changed.
bv includes a comprehensive benchmark suite for performance validation:
# Run all benchmarks
./scripts/benchmark.sh
# Save current performance as baseline
./scripts/benchmark.sh baseline
# Compare against baseline (requires benchstat)
./scripts/benchmark.sh compare
# Quick benchmarks (CI mode)
./scripts/benchmark.sh quickBenchmark Categories:
- Full Analysis: End-to-end
Analyze()pipeline at various scales - Individual Algorithms: PageRank, Betweenness, HITS, TopoSort isolation
- Pathological Graphs: Stress tests for timeout protection (many cycles, complete graphs)
- Timeout Verification: Ensures large graphs don't hang
Timeout Protection: All expensive algorithms (Betweenness, PageRank, HITS, Cycle detection) have 500ms timeouts to prevent blocking on large or pathological graphs.
Detailed Tuning Guide: For comprehensive performance documentation including troubleshooting, size-based algorithm selection, and tuning options, see docs/performance.md.
Q: My icons look weird / text is misaligned.
bvrequires a terminal with TrueColor support and a Nerd Font installed.- Recommended: Nerd Fonts (e.g., "JetBrains Mono Nerd Font" or "Hack Nerd Font").
- Terminals: Windows Terminal, iTerm2, Alacritty, Kitty, WezTerm.
Q: I see "Cycles Detected" in the dashboard. What now?
A: A cycle (e.g., A → B → A) means your project logic is broken; no task can be finished first. Use the Insights Dashboard (i) to find the specific cycle members, then use bd to remove one of the dependency links (e.g., bd unblock A --from B).
Q: Does this work with Jira/GitHub?
A: bv is data-agnostic. The Beads data schema supports an external_ref field. If you populate your .beads/beads.jsonl file with issues from external trackers (e.g., using a custom script or sync tool), bv will render them alongside your local tasks. Future versions of the bd CLI may support native syncing, but bv is ready for that data today.

bv automatically detects your terminal capabilities to render the best possible UI. It looks for .beads/beads.jsonl in your current directory.
| Variable | Description | Default |
|---|---|---|
BEADS_DIR |
Custom beads directory path. When set, overrides the default .beads directory lookup. |
.beads in cwd |
BV_SEMANTIC_EMBEDDER |
Semantic embedding provider for bv --search and TUI semantic mode. |
hash |
BV_SEMANTIC_DIM |
Embedding dimension for semantic search index. | 384 |
BV_SEMANTIC_MODEL |
Provider-specific model name for semantic search (optional). | (empty) |
Use cases for BEADS_DIR:
- Monorepos: Single beads directory shared across multiple packages
- Non-standard layouts: Projects where
.beadsisn't in the working directory - Testing: Point to test fixtures without changing directory
- Cross-directory access: View beads from anywhere on the filesystem
# Example: Point to a different beads directory
BEADS_DIR=/path/to/shared/beads bv
# Example: Use in monorepo
export BEADS_DIR=$(git rev-parse --show-toplevel)/.beadsThe UI uses a visually distinct, high-contrast theme inspired by Dracula Principles to ensure readability.

- Deterministic JSON contracts: robot commands emit stable field names, stable ordering (ties broken by ID), and include
data_hash,analysis_config, andcomputed_atso multiple calls can be correlated safely. - Health flags: every expensive metric reports status (
computed,approx,timeout,skipped) plus elapsed ms and (when sampled) the sample size used. - Consistent cache: robot subcommands share the same analyzer/cache keyed by the issue data hash, avoiding divergent outputs across
--robot-insights,--robot-plan, and--robot-priority. - Instant + eventual completeness: Phase 1 metrics are available immediately; Phase 2 fills in and the status flags tell you when it is done or if it degraded.
.beads/beads.jsonl
↓ tolerant loader (BOM strip, 10MB lines, skip malformed)
↓ graph builder (blocking deps only)

- Hash and config travel with every robot payload so downstream consumers can verify consistency.
- PageRank: “blocking authority” — foundational tasks with many (or important) dependents.
- Betweenness: “bridges” — nodes on many shortest paths; bottlenecks between clusters.
- HITS: hubs (aggregators) vs authorities (prerequisites).
- Critical-path depth: longest downstream chain length; zero slack keystones.
- Eigenvector: influence via influential neighbors.
- Density, degree, topo sort: structural backbone.
- Cycles: detected via Tarjan SCC +
DirectedCyclesIn; capped with timeouts and stored count. - Each appears in robot insights with its status flag and, when ready, per-issue scores.
- Phase 1 (instant): degree, topo sort, density; always present.
- Phase 2 (async): PageRank, Betweenness, HITS, Eigenvector, Critical Path, Cycles; 500ms defaults with size-based adjustments. Status flag reflects computed/approx/timeout/skipped.
- Per-metric status:
computed(full),approx(e.g., sampled betweenness),timeout(fallback),skipped(size/density guard). - Payload example:
{ "status": { "pagerank": {"state":"computed","ms":142}, "betweenness": {"state":"approx","ms":480,"sample":120}, "cycles": {"state":"timeout","ms":500,"reason":"deadline"} } }
- Actionable set: open/in-progress issues with no open blocking dependencies.
- Unblocks: for each actionable, list of issues that would become actionable if it closed (no other open blockers).
- Tracks: undirected connected components group actionable items into parallelizable streams.
- Summary: highest-impact item = max unblocks, then priority, then ID for determinism.
- Composite score weights: PageRank 30%, Betweenness 30%, blocker ratio 20%, staleness 10%, priority boost 10%.
- Thresholds: high PR >0.30, high BW >0.50, staleness ~14 days, min confidence 0.30 by default.
- Direction: “increase” or “decrease” priority derived from score vs current priority; confidence blends signal count, strength, and score delta.
- When stdout is non-TTY or
BV_ROBOT=1,--diff-sinceauto-emits JSON (or requires--robot-diffin strict setups); resolved revision is echoed in the payload. - TUI time-travel badges:
[NEW],[CLOSED],[MODIFIED],[REOPENED], matching the robot diff summary.
- Two-phase analysis with size-aware configs (approx betweenness on large sparse graphs, cycle caps, HITS skipped on dense XL graphs).
- 500ms default timeouts per expensive metric; results marked with status.
- Cache TTL keeps repeated robot calls fast on unchanged data; hash mismatch triggers recompute.
- Bench quick check:
./scripts/benchmark.sh quickor diagnostics viabv --profile-startup.
- Loader skips malformed lines with warnings, strips UTF-8 BOM, tolerates large lines (10MB).
- Beads file discovery order: beads.jsonl → beads.base.jsonl → issues.jsonl; skips backups/merge artifacts/deletions manifests.
- Live reload is debounced; update check is non-blocking with graceful failure on network issues.
- Typical pipeline:
bv --robot-insights > insights.json bv --robot-plan | jq '.plan.summary' bv --robot-priority | jq '.recommendations[0]' bv --check-drift --robot-drift --diff-since HEAD~5 > drift.json
- Use
data_hashto ensure all artifacts come from the same analysis run; fail CI if hashes diverge. - Exit codes: drift check (0 ok, 1 critical, 2 warning).
- Empty metric maps → Phase 2 still running or timed out; check status flags.
- Large payloads → use jq to slice top items; re-run after filtering via recipes.
- Missing cycles → likely skipped/timeout; see
status.cycles. - Inconsistent outputs between commands → compare
data_hash; rerun if different.
- Local-first: all analysis happens on your repo's JSONL; no network required for robots.
- Hooks and exports are opt-in; update checks are silent and tolerate network failures without impacting startup.

About Contributions: Please don't take this the wrong way, but I do not accept outside contributions for any of my projects. I simply don't have the mental bandwidth to review anything, and it's my name on the thing, so I'm responsible for any problems it causes; thus, the risk-reward is highly asymmetric from my perspective. I'd also have to worry about other "stakeholders," which seems unwise for tools I mostly make for myself for free. Feel free to submit issues, and even PRs if you want to illustrate a proposed fix, but know I won't merge them directly. Instead, I'll have Claude or Codex review submissions via
ghand independently decide whether and how to address them. Bug reports in particular are welcome. Sorry if this offends, but I want to avoid wasted time and hurt feelings. I understand this isn't in sync with the prevailing open-source ethos that seeks community contributions, but it's the only way I can move at this velocity and keep my sanity.
