       - Dependency-aware: Track blockers and relationships between issues

     

       10
       10
       +
       - Git-friendly: Auto-syncs to JSONL for version control

     

       11
       11
       +
       - Agent-optimized: JSON output, ready work detection, discovered-from links

     

       12
       12
       +
       - Prevents duplicate tracking systems and confusion

       41
       41
       +
       - `feature` - New functionality

     

       42

       46
       46
       +
       ### Priorities

     

       47
       47
       +
       

     

       48
       48
       +
       - `0` - Critical (security, data loss, broken builds)

     

       49
       49
       +
       - `1` - High (major features, important bugs)

     

       50
       50
       +
       - `2` - Medium (default, nice-to-have)

     

       51
       51
       +
       - `3` - Low (polish, optimization)

     

       52
       52
       +
       - `4` - Backlog (future ideas)

     

       53
       53
       +
       

     

       54
       54
       +
       ### Workflow for AI Agents

     

       55
       55
       +
       

     

       56
       56
       +
       1. **Check ready work**: `bd ready` shows unblocked issues

     

       57
       57
       +
       2. **Claim your task**: `bd update <id> --status in_progress`

     

       58
       58
       +
       3. **Work on it**: Implement, test, document

     

       59
       59
       +
       4. **Discover new work?** Create linked issue:

     

       60
       60
       +
          - `bd create "Found bug" -p 1 --deps discovered-from:<parent-id>`

     

       61
       61
       +
       5. **Complete**: `bd close <id> --reason "Done"`

     

       62
       62
       +
       6. **Commit together**: Always commit the `.beads/issues.jsonl` file together with the code changes so issue state stays in sync with code state

     

       63
       63
       +
       

     

       64
       64
       +
       ### Auto-Sync

     

       65
       65
       +
       

     

       66
       66
       +
       bd automatically syncs with git:

     

       67
       67
       +
       - Exports to `.beads/issues.jsonl` after changes (5s debounce)

     

       68
       68
       +
       - Imports from JSONL when newer (e.g., after `git pull`)

     

       69
       69
       +
       - No manual export/import needed!

     

       70
       70
       +
       

     

       71
       71
       +
       ### MCP Server (Recommended)

     

       72
       72
       +
       

     

       73
       73
       +
       If using Claude or MCP-compatible clients, install the beads MCP server:

     

       74
       74
       +
       

     

       75
       75
       +
       ```bash

     

       76
       76
       +
       pip install beads-mcp

     

       77
       77
       +
       ```

     

       78
       78
       +
       

     

       79
       79
       +
       Add to MCP config (e.g., `~/.config/claude/config.json`):

     

       80
       80
       +
       ```json

     

       81
       81
       +
       {

     

       82
       82
       +
         "beads": {

     

       83
       83
       +
           "command": "beads-mcp",

     

       84
       84
       +
           "args": []

     

       85
       85
       +
         }

     

       86
       86
       +
       }

     

       87
       87
       +
       ```

     

       88
       88
       +
       

     

       89
       89
       +
       Then use `mcp__beads__*` functions instead of CLI commands.

     

       90
       90
       +
       

     

       91

       ### Managing AI-Generated Planning Documents

     

       92
       92
       +
       

     

       93
       93
       +
       AI assistants often create planning and design documents during development:

     

       94
       94
       +
       - PLAN.md, IMPLEMENTATION.md, ARCHITECTURE.md

     

       95
       95
       +
       - DESIGN.md, CODEBASE_SUMMARY.md, INTEGRATION_PLAN.md

     

       96
       96
       +
       - TESTING_GUIDE.md, TECHNICAL_DESIGN.md, and similar files

     

       97
       97
       +
       

     

       98
       98
       +
       **Best Practice: Use a dedicated directory for these ephemeral files**

     

       99
       99
       +
       

     

       100
       100
       +
       **Recommended approach:**

     

       101
       101
       +
       - Create a `history/` directory in the project root

     

       102
       102
       +
       - Store ALL AI-generated planning/design docs in `history/`

     

       103
       103
       +
       - Keep the repository root clean and focused on permanent project files

     

       104
       104
       +
       - Only access `history/` when explicitly asked to review past planning

     

       105
       105
       +
       

     

       106
       106
       +
       **Example .gitignore entry (optional):**

     

       107
       107
       +
       ```

     

       108
       108
       +
       # AI planning documents (ephemeral)

     

       109
       109
       +
       history/

     

       110
       110
       +
       ```

     

       111
       111
       +
       

     

       112
       112
       +
       **Benefits:**

     

       113
       113
       +
       - ✅ Clean repository root

     

       114
       114
       +
       - ✅ Clear separation between ephemeral and permanent documentation

     

       115
       115
       +
       - ✅ Easy to exclude from version control if desired

     

       116
       116
       +
       - ✅ Preserves planning history for archeological research

     

       117
       117
       +
       - ✅ Reduces noise when browsing the project

     

       118
       118
       +
       

     

       119
       119
       +
       ### Important Rules

     

       120
       120
       +
       

     

       121
       121
       +
       - ✅ Use bd for ALL task tracking

     

       122
       122
       +
       - ✅ Always use `--json` flag for programmatic use

     

       123
       123
       +
       - ✅ Link discovered work with `discovered-from` dependencies

     

       124
       124
       +
       - ✅ Check `bd ready` before asking "what should I work on?"

     

       125
       125
       +
       - ✅ Store AI planning docs in `history/` directory

     

       126
       126
       +
       - ❌ Do NOT create markdown TODO lists

     

       127
       127
       +
       - ❌ Do NOT use external issue trackers

     

       128
       128
       +
       - ❌ Do NOT duplicate tracking systems

     

       129
       129
       +
       - ❌ Do NOT clutter repo root with planning documents

     

       130
       130
       +

       ## DPoP Token Binding

     

       114
       114

       115

       DPoP (Demonstrating Proof-of-Possession) binds access tokens to client-controlled cryptographic keys, preventing token theft and replay attacks.

     

       116
       116
       +
       

     

       117
       117
       +
       ### What is DPoP?

     

       118
       118
       +
       

     

       119
       119
       +
       DPoP is an OAuth extension (RFC 9449) that adds proof-of-possession semantics to bearer tokens. When a PDS issues a DPoP-bound access token:

     

       120
       120
       +
       

     

       121
       121
       +
       1. Access token contains `cnf.jkt` claim (JWK thumbprint of client's public key)

     

       122
       122
       +
       2. Client creates a DPoP proof JWT signed with their private key

     

       123
       123
       +
       3. Server verifies the proof signature and checks it matches the token's `cnf.jkt`

     

       124
       124
       +
       

     

       125
       125
       +
       ### CRITICAL: DPoP Security Model

     

       126
       126
       +
       

     

       127
       127
       +
       > ⚠️ **DPoP is an ADDITIONAL security layer, NOT a replacement for token signature verification.**

     

       128
       128
       +
       

     

       129
       129
       +
       The correct verification order is:

     

       130
       130
       +
       1. **ALWAYS verify the access token signature first** (via JWKS, HS256 shared secret, or DID resolution)

     

       131
       131
       +
       2. **If the verified token has `cnf.jkt`, REQUIRE valid DPoP proof**

     

       132
       132
       +
       3. **NEVER use DPoP as a fallback when signature verification fails**

     

       133
       133
       +
       

     

       134
       134
       +
       **Why This Matters**: An attacker could create a fake token with `sub: "did:plc:victim"` and their own `cnf.jkt`, then present a valid DPoP proof signed with their key. If we accept DPoP as a fallback, the attacker can impersonate any user.

     

       135

       ### When DPoP is Required

     

       160
       160
       +
       

     

       161
       161
       +
       DPoP verification is **REQUIRED** when:

     

       162
       162
       +
       - Access token signature has been verified AND

     

       163
       163
       +
       - Access token contains `cnf.jkt` claim (DPoP-bound)

     

       164
       164
       +
       

     

       165
       165
       +
       If the token has `cnf.jkt` but no DPoP header is present, the request is **REJECTED**.

     

       166
       166
       +
       

     

       167

       ### Replay Protection

     

       168

       169
       169
       +
       DPoP proofs include a unique `jti` (JWT ID) claim. The server tracks seen `jti` values to prevent replay attacks:

     

       170
       170
       +
       

     

       171
       171
       +
       ```go

     

       172
       172
       +
       // Create a verifier with replay protection (default)

     

       173
       173
       +
       verifier := auth.NewDPoPVerifier()

     

       174
       174
       +
       defer verifier.Stop() // Stop cleanup goroutine on shutdown

     

       175
       175
       +
       

     

       176
       176
       +
       // The verifier automatically rejects reused jti values within the proof validity window (5 minutes)

     

       177
       177
       +
       ```

       207
       207
       +
       The DPoP header contains a JWT with:

       +
       

     

       209

       **Header**:

     

       210
       210
       +
       - `typ`: `"dpop+jwt"` (required)

     

       211
       211
       +
       - `alg`: `"ES256"` (or other supported algorithm)

     

       212
       212
       +
       - `jwk`: Client's public key (JWK format)

     

       213
       213
       +
       

     

       214
       214
       +
       **Claims**:

     

       215
       215
       +
       - `jti`: Unique proof identifier (tracked for replay protection)

     

       216
       216
       +
       - `htm`: HTTP method (e.g., `"POST"`)

     

       217
       217
       +
       - `htu`: HTTP URI (without query/fragment)

     

       218
       218

       ### ✅ Implemented

     
···

       120
       247
        
       - Required claims validation (sub, iss)

     

       121
       248
        
       - Key caching with TTL

     

       122
       249
        
       - Secure error messages (no internal details leaked)

     

       250
       250
       +
       - **DPoP proof verification** (proof-of-possession for token binding)

     

       251
       251
       +
       - **DPoP thumbprint validation** (prevents token theft attacks)

     

       252
       252
       +
       - **DPoP freshness checks** (5-minute proof validity window)

     

       253
       253
       +
       - **DPoP replay protection** (jti tracking with in-memory cache)

     

       254
       254
       +
       - **Secure DPoP model** (DPoP required AFTER signature verification, never as fallback)
