kc-plugin-forge-doc-sync

kc-plugin-forge-doc-sync is a skill for Claude Code from iamcxa/kc-claude-plugins. It costs 59 tokens per session (1,331 once invoked), scanned A, original, MIT.

A documentation maintenance tool that compares plugin source code with its documentation and updates or reports gaps. It can also use usage history from journals and memory when enriching the docs.

In plain words
What is it for?
Synchronizing plugin documentation, checking it without writing changes, updating one section, and finding missing or stale explanations.
Why use it?
It helps catch features, options, and behavior that changed in code but were not reflected in the documentation.

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

kc-plugin-forge-doc-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 5d 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.

Routing

Input Route
bare invocation → Full Sync
--check → Report Only
--auto → Full Sync (skip confirmation)
--section <doc-file> → Targeted Sync (one doc file)

Phase 1: Static Scan

  1. Read reference/doc-sync-context.md → load Source Map, Doc Structure, Post-Sync Hooks
  2. Inventory source files:
    • Glob skills/*/SKILL.md → for each: extract skill name, description, all --flags, modes (from routing tables), key concepts
    • Glob hooks/ → for each: extract event type, trigger condition, affected tools
  3. Inventory documentation:
    • Glob docs/*.md + README.md → for each: extract title, section headings, mentioned features, example count
  4. Cross-reference: for each Source Map entry, search its Doc Target for coverage of every extracted feature
  5. Classify gaps:
    • Critical: source feature exists, zero mention in any doc
    • Warning: mentioned in one doc but not explained (e.g., flag listed in table but no usage guide)
    • Info: documented but could be improved (missing example, stale cross-reference)
  6. Meta-doc consistency check: verify CLAUDE.md skill/agent counts, README docs table completeness, plugin.json description accuracy

If --section <doc-file>: filter Source Map to entries targeting that doc file only.

Output: gap_report + feature_inventory

Phase 2: History Enrichment

Prerequisite: MCP tools episodic-memory and private-journal. If unavailable, skip Phase 2 with warning: "History enrichment skipped — MCP tools unavailable. Running static-only mode." Proceed to Phase 3 with unenriched gaps.

  1. Search episodic memory: search("kc-plugin-forge") → extract usage patterns, user workflows, reported issues
  2. Search journal: search_journal("kc-plugin-forge") → extract technical insights, debug findings, failed attempts
  3. Read MEMORY.md → extract known plugin knowledge entries
  4. Enrich each gap:
    • History mentions this feature with usage context? → add context to gap (improves doc writing quality)
    • History contradicts current docs? → escalate gap to accuracy_risk (priority fix)
  5. Features found in history but NOT in gap report → add as new Info-level gap ("undocumented but used")

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
