What it does

Document Sync is an agent skill from ananddtyagi/cc-marketplace. A robust skill that analyzes your app's actual codebase, tech stack, configuration, and architecture to ensure ALL documentation is current and accurate. It never assumes—always verifies and compares the live system with every documentation file to detect code-doc drift and generate actionable updates.

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including scripts, reference files and assets (for example `assets/config_schemas/document-sync-schema.json`, `assets/report_templates/update_plan.md` and `assets/report_templates/verification_report.md`).

The repository describes itself as: Marketplace repo for Claude Code Plugins.

Example prompts

  • “/document-sync”

Requirements

  • Python 3

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Full System Scan
  2. Documentation Verification
  3. Automated or Assisted Document Updating

What it can do on your machine

Read from SKILL.md and the folder at commit b643305. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 3 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Document Sync loads about 2k tokens when it runs, and up to ~9.4k if it reads all its reference files. Until then it costs about 79 tokens; SKILL.md has 765 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~79
When it runs · the whole SKILL.md, loaded when a task matches
~2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~9.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:119
    nfig.md` section on env vars (now using `.env.local`)

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 765 words (~1,982 tokens).

“This skill provides comprehensive documentation synchronization by analyzing your actual codebase, tech stack, configuration, and architecture to ensure all documentation remains current and accurate. It operates on a "verify, never assume" principle, performing end-to-end comparisons against real code and dependencies…”

How do I install Document Sync in Claude Code?

Run `npx skills add ananddtyagi/cc-marketplace --skill document-sync -a claude-code`. Or copy the skill folder (plugins/claude-dev-infrastructure/skills/document-sync in ananddtyagi/cc-marketplace) into .claude/skills/document-sync in your project. Claude Code loads it when a task matches its description.

How do I install Document Sync in Codex?

Run `npx skills add ananddtyagi/cc-marketplace --skill document-sync -a codex`. Or copy the skill folder (plugins/claude-dev-infrastructure/skills/document-sync in ananddtyagi/cc-marketplace) into .agents/skills/document-sync in your project. Codex loads it when a task matches its description.

Can I use Document Sync in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ananddtyagi/cc-marketplace --skill document-sync -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/document-sync, .gemini/skills/document-sync, .github/skills/document-sync and .opencode/skills/document-sync in your project.

What does Document Sync need to run?

Going by SKILL.md and its folder, Document Sync needs Python for the scripts in its folder and the command-line tools its instructions call (python3). Our summary lists: Python 3.

Does Document Sync access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Document Sync safe to install?

Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Document Sync use?

No licence was found for Document Sync or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.

How many tokens does Document Sync use?

About 2k tokens (SKILL.md is roughly 7.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 7.4k tokens, read only when the agent opens those files.

What are the alternatives to Document Sync?

Skills that share tags, products or a category with Document Sync: Claude-Mem Cloud Sync (thedotmack/claude-mem, 97k stars), Agent Code Analyzer (ruvnet/ruflo, 74k stars), Agent Pagerank Analyzer (ruvnet/ruflo, 74k stars) and Agent Performance Analyzer (ruvnet/ruflo, 74k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
