Agent Skills: blueprint-sync-ids

Scan all PRDs, ADRs, PRPs, and work-orders, assign IDs to documents missing them, and update the manifest registry.

When to Use This Skill

| Use this skill when... | Use blueprint-sync instead when... | |---|---| | You're assigning PRD-NNN / ADR-NNNN / PRP-NNN / WO-NNN to docs missing them | You want to detect modified or stale generated content (not IDs) | | You're previewing ID assignments with --dry-run | You're reconciling drift between .claude/rules/ and the manifest | | You want to create GitHub issues for orphan docs via --link-issues | Use document-linking instead for runtime cross-doc traceability |

Flags

| Flag | Description | |------|-------------| | --dry-run | Preview changes without modifying files | | --link-issues | Also create GitHub issues for orphan documents |

Interaction Mode

Before any closing AskUserQuestion menu, resolve the automation config:

bash "${CLAUDE_SKILL_DIR}/../../scripts/get-automation-config.sh"

When EFFECTIVE_INTERACTION_MODE=quiet and this invocation was automation-initiated (autopilot, session bookend, drift-nudge follow-up — not a slash command the user typed), skip closing navigation menus ("what next?" / "create another?" style): apply the safe default and end with a one-line receipt instead. Quiet mode never skips confirmation gates that guard writes — only navigation menus. A direct user invocation always behaves fully interactively (explicit intent overrides quiet; see ADR-0020).

Prerequisites

• Blueprint initialized (docs/blueprint/manifest.json exists)
• At least one document exists in docs/prds/, docs/adrs/, docs/prps/, or docs/blueprint/work-orders/

Steps

Step 1: Initialize ID Registry

Check if id_registry exists in manifest:

jq -e '.id_registry' docs/blueprint/manifest.json >/dev/null 2>&1

If not, initialize it:

{
  "id_registry": {
    "last_prd": 0,
    "last_prp": 0,
    "documents": {},
    "github_issues": {}
  }
}

Step 2: Run the read-only ID audit

Run the helper. It owns the read-only scan: frontmatter id: extraction across PRDs/ADRs/PRPs/work-orders, deriving the expected ADR-NNNN / WO-NNN from each filename, flagging NEEDS_ID (no id) and id_mismatch (frontmatter id disagrees with the filename-derived expectation), and building the reverse github_issues index from the manifest registry:

bash "${CLAUDE_SKILL_DIR}/scripts/blueprint-sync-ids.sh" --home-dir "$HOME" --project-dir "$(pwd)"

Parse STATUS= and ISSUES: from the output:

• PRD_NEEDS_ID / ADR_NEEDS_ID / PRP_NEEDS_ID / WO_NEEDS_ID and the needs_id issues are the documents to assign IDs to in Step 7 (each carries DOC= and, for ADRs/WOs, the EXPECTED= filename-derived ID).
• ADR_MISMATCH / WO_MISMATCH and the id_mismatch issues (HAS= vs EXPECTED=) are documents whose frontmatter id disagrees with their filename — reconcile these in Step 7, never silently. STATUS=ERROR indicates at least one mismatch.
• GH_ISSUE_MAPPINGS and MANIFEST_PRESENT summarise the reverse-index build (Step 9 detail below).

The audit is read-only; it makes no edits. Surface its counts as the Step 6 report and proceed to the mutating steps.

Step 7: Assign IDs (unless --dry-run)

For each document needing an ID:

PRDs:

1. Get next PRD number: jq '.id_registry.last_prd' manifest.json + 1
2. Generate ID: PRD-NNN (zero-padded)
3. Insert into frontmatter after first ---:

   id: PRD-001
   

4. Update manifest: increment last_prd, add to documents

ADRs:

1. Derive ID from filename: 0003-title.md → ADR-0003
2. Insert into frontmatter
3. Add to manifest documents

PRPs:

1. Get next PRP number: jq '.id_registry.last_prp' manifest.json + 1
2. Generate ID: PRP-NNN
3. Insert into frontmatter
4. Update manifest: increment last_prp, add to documents

Work-Orders:

1. Derive ID from filename: 003-task.md → WO-003
2. Insert into frontmatter
3. Add to manifest documents

Step 8: Extract Titles and Links

For each document, also extract:

• Title: First # heading or frontmatter name/title field
• Existing links: relates-to, implements, github-issues from frontmatter
• Status: From frontmatter

Store in manifest registry:

{
  "documents": {
    "PRD-001": {
      "path": "docs/prds/user-auth.md",
      "title": "User Authentication",
      "status": "Active",
      "relates_to": ["ADR-0003"],
      "github_issues": [42],
      "created": "2026-01-15"
    }
  }
}

Step 9: Build GitHub Issue Index

The Step 2 audit already groups the manifest's per-document github_issues arrays into the reverse index (GH_ISSUE_MAPPINGS= reports how many distinct issue numbers map to documents). Write that reverse index into the manifest:

{
  "github_issues": {
    "42": ["PRD-001", "PRP-002"],
    "45": ["WO-003"]
  }
}

Step 10: Create Issues for Orphans (if --link-issues)

For each document without github-issues:

question: "Create GitHub issue for {ID}: {title}?"
options:
  - label: "Yes, create issue"
    description: "Creates [{ID}] {title} issue"
  - label: "Skip this one"
    description: "Leave unlinked for now"
  - label: "Skip all remaining"
    description: "Don't prompt for more orphans"

If yes:

gh issue create \
  --title "[{ID}] {title}" \
  --body "## {Document Type}

**ID**: {ID}
**Document**: \`{path}\`

{Brief description from document}

---
*Auto-generated by /blueprint:sync-ids*" \
  --label "{type-label}"

Update document frontmatter and manifest with new issue number.

Step 11: Update task registry

Update the task registry entry in docs/blueprint/manifest.json:

jq --arg now "$(date -u +%Y-%m-%dT%H:%M:%SZ)" \
  --argjson processed "${DOCS_CHECKED:-0}" \
  --argjson created "${IDS_ASSIGNED:-0}" \
  '.task_registry["sync-ids"].last_completed_at = $now |
   .task_registry["sync-ids"].last_result = "success" |
   .task_registry["sync-ids"].stats.runs_total = ((.task_registry["sync-ids"].stats.runs_total // 0) + 1) |
   .task_registry["sync-ids"].stats.items_processed = $processed |
   .task_registry["sync-ids"].stats.items_created = $created' \
  docs/blueprint/manifest.json > tmp.json && mv tmp.json docs/blueprint/manifest.json

Step 12: Final Report

ID Sync Complete

Assigned IDs:
- PRD-003: docs/prds/payment-flow.md
- PRD-004: docs/prds/notifications.md
- PRP-005: docs/prps/stripe-integration.md

Updated Manifest:
- last_prd: 4
- last_prp: 5
- documents: 22 entries
- github_issues: 18 mappings

{If --link-issues:}
Created GitHub Issues:
- #52: [PRD-003] Payment Flow
- #53: [PRP-005] Stripe Integration

Still orphaned (no GitHub issues):
- ADR-0004: Database Migration Strategy
- WO-008: Add error handling

Run `/blueprint:status` to see full traceability report.

Error Handling

| Condition | Action | |-----------|--------| | No manifest | Error: Run /blueprint:init first | | No documents found | Warning: No documents to scan | | Frontmatter parse error | Warning: Skip file, report for manual fix | | gh not available | Skip issue creation, warn user | | Write permission denied | Error: Check file permissions |
