doc-sync-check

doc-sync-check is a skill for Claude Code, Codex from ZeroDeng01/sublinkPro. It costs 34 tokens per session (2,424 once invoked), scanned A, original, MIT.

A checklist that checks whether code changes also require updates to API, configuration, feature, or deployment documentation. It is run automatically as part of a post-development workflow.

In plain words
What is it for?
Use it after changes to user-visible behavior, API endpoints, configuration options, installation steps, or developer workflows. It identifies the documentation files that should be reviewed.
Why use it?
It helps prevent documentation from becoming inaccurate after the code changes. Keeping docs updated in the same pull request makes changes easier for users and maintainers to follow.

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

doc-sync-check 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.

Documentation Sync Check Skill

Checklist for ensuring documentation stays synchronized with code changes.

When to use this skill

Use this skill when changes affect:

  • User-visible behavior or features
  • API contracts or endpoints
  • Configuration options or environment variables
  • Deployment or installation procedures
  • Developer workflows or contribution processes
  • Build or validation processes

Core Principle

Documentation must be updated in the same PR as the code change. Outdated docs are a maintenance burden and user pain point.

Prerequisites

Before running this checklist:

  1. Identify which documentation files might be affected
  2. Read AGENTS.md section "Documentation expectations"
  3. Review CONTRIBUTING.md for documentation standards

Quick Reference: Which Docs to Update

Change Type Docs to Check
User-facing feature README.md + .zh-CN.md, docs/features/*.md + .zh-CN.md
Configuration option docs/configuration.md + .zh-CN.md, example configs
Installation/deployment docs/installation.md + .zh-CN.md, skill-sublinkpro/reference/deploy.md
API endpoint skill-sublinkpro/reference/api.md
Developer workflow docs/development.md + .zh-CN.md, CONTRIBUTING.md + .zh-CN.md
Architecture/guidelines AGENTS.md
New documentation skill-sublinkpro/reference/docs.md (documentation map)

Feature Documentation Checklist

When user-facing features change:

README updates
  • Updated README.md if feature overview affected
  • Updated README.zh-CN.md (Chinese version)
  • Updated feature list if new feature added
  • Updated screenshots/GIFs if UI changed significantly
Feature docs
  • Updated relevant docs/features/*.md file
  • Updated corresponding .zh-CN.md file
  • Added new feature doc if new feature (both languages)
  • Updated examples and usage instructions
  • Verified code samples are accurate
Cross-references
  • Updated links from README to feature docs
  • Updated internal cross-references in docs
  • Added new doc to docs/ index/TOC (if applicable)

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.
