sync-docs

同步Anthropic官方文档并分析其对项目组件的影响。运行docs/reference/update-claude-docs.sh，计算差异，并报告对技能验证器、插件及项目文档的影响。当用户提到“同步文档”、“更新参考文档”、“刷新文档”或“检查文档变化”时，就使用此技能。

  Sync official Anthropic documentation and analyze impact on project components.
  Runs docs/reference/update-claude-docs.sh, computes diffs, and reports impacts
  on the skill validator, plugins, and project documentation. Use when user
  mentions "sync docs", "update reference docs", "refresh docs", or "check doc changes".

Sync Docs

Sync official Anthropic documentation into docs/reference/ and produce an impact analysis report.

Quick Start

Run the sync and diff script:

bash
scripts/sync_and_diff.py

Preview changes without overwriting:

bash
scripts/sync_and_diff.py --dry-run

Execution

Phase 1: Sync & Diff

  1. •Execute scripts/sync_and_diff.py (or with --dry-run if $ARGUMENTS contains --dry-run)
  2. •Parse the JSON output from stdout
  3. •Display a summary table of changed/unchanged files

Phase 2: Impact Analysis

For each changed file, perform the following analysis. See WORKFLOW.md for detailed steps.

2a. Skill Validator Impact (CRITICAL priority)

Check discrepancies in the JSON output:

  • •skill_frontmatter_keys.in_docs_not_validator (CRITICAL): New fields in SKILLS.md the validator will reject as unknown (FM009). Report exact fields and line in validate_skill.py to update (ALLOWED_FRONTMATTER_KEYS, ~line 151).
  • •skill_frontmatter_keys.in_validator_not_docs (WARNING): Fields the validator allows but SKILLS.md no longer documents. May be from SUBAGENTS.md (valid for context: fork) or deprecated.
  • •subagent_frontmatter_keys (INFO): New subagent fields from SUBAGENTS.md. Not all are valid in skill frontmatter — report for context. Only flag fields that overlap with skill usage (e.g., maxTurns, mcpServers, memory, skills).
  • •hook_events.in_docs_not_validator (CRITICAL): New hook events the validator will reject (HK001). Report the line to update (VALID_HOOK_EVENTS, ~line 1021).
  • •hook_events.in_validator_not_docs (WARNING): Hook events the validator knows but docs no longer list.
  • •memory_scopes: Review manually if SUBAGENTS.md changed — check if memory scope options expanded.

2b. Plugin Component Impact (WARNING priority)

For each changed synced doc, identify the conceptual areas that changed (new fields, deprecated features, renamed concepts). Then:

  1. •Use Grep to search plugins/*/ for references to changed concepts
  2. •Flag plugins using deprecated patterns
  3. •Note new capabilities not yet leveraged (as INFO)

2c. Project Documentation Impact (WARNING priority)

Check these files for stale references to synced doc content:

  • •CLAUDE.md — Plugin Component Guidelines section, Key Documentation Files section
  • •docs/README.md — Synced Documentation section, learning paths
  • •docs/SKILL_DEVELOPMENT_BEST_PRACTICES.md — Frontmatter reference, patterns

Output Format

Present findings as a structured report:

code
=== Documentation Sync Impact Report ===

## Sync Summary
| File | Status | +Lines | -Lines | New Sections | Removed Sections |
|------|--------|--------|--------|--------------|-----------------|
...

## CRITICAL: Skill Validator Updates Required
(List each discrepancy with file, line number, and fix)

## WARNING: Plugin Components Affected
(List affected plugins and what changed)

## WARNING: Project Documentation Stale
(List affected doc files and what to update)

## INFO: New Capabilities Available
(List new features from updated docs that could be leveraged)

If no files changed, report: "All documentation is up to date. No impacts detected."
