blueprint-sync

blueprint-sync is a skill for Claude Code from laurigates/claude-plugins. It costs 36 tokens per session (1,946 once invoked), scanned A, original, MIT.

A checker for generated project files that detects when they no longer match their source documents or rules. It reports stale content and offers ways to regenerate or keep changes.

In plain words
What is it for?
Use it after PRD or rule changes to inspect drift and choose regeneration, promotion, or preservation options.
Why use it?
It helps prevent generated skills and rules from quietly falling out of sync with the project plans that produced them.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

blueprint-sync scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 207 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Check the status of generated content and offer options for modified or stale files.

When to Use This Skill

Use this skill when... Use blueprint-promote instead when...
You want to detect stale or modified generated rules/skills You've decided to keep one specific edited rule (single artifact)
You're reconciling drift between .claude/rules/ and the manifest You want to acknowledge modifications and stop sync warnings
You want regenerate/promote/keep options for many files at once Use blueprint-generate-rules instead to (re)generate from PRDs
You preview status with --dry-run before changing anything Use blueprint-sync-ids instead for ID assignment, not content drift

Flags

Flag Description
--dry-run Preview sync status report without interactive prompts or file modifications

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).

Steps

Purpose:

  • Detect when generated skills/commands have been manually modified
  • Detect when source PRDs have changed (making generated content stale)
  • Offer appropriate actions: regenerate, promote to custom, or keep as-is
  1. Read manifest:
    cat docs/blueprint/manifest.json
    
    • Extract generated.rules section
    • If no generated content, report "Nothing to sync"

1a. Detect pre-contract records (issue #2868):
