doc-sync

A documentation synchronizer for keeping CLAUDE.md navigation files and README.md project notes aligned across a repository. A repository is the folder containing a project's code and related files.

In plain words
What is it for?
Use it to audit the whole repository or a specific directory, then update the relevant navigation and project-knowledge documents.
Why use it?
It finds documentation that is missing, outdated, or inconsistent within the chosen part of the project.

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 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 2d 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 — 223 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Doc Sync

Maintains the CLAUDE.md navigation hierarchy and README.md invisible knowledge docs across a repository. This skill is self-contained and performs all documentation work directly.

Documentation Conventions

For authoritative CLAUDE.md and README.md format specification:

The conventions/ directory contains all universal documentation standards.

Scope Resolution

Determine scope FIRST:

User Request Scope
"sync docs" / "update documentation" / no specific path REPOSITORY-WIDE
"sync docs in src/validator/" DIRECTORY: src/validator/ and descendants
"update CLAUDE.md for parser.py" FILE: single file's parent directory

For REPOSITORY-WIDE scope, perform a full audit. For narrower scopes, operate only within the specified boundary.

Workflow

Phase 1: Discovery

Map directories requiring CLAUDE.md verification:

# Find all directories (excluding .git, node_modules, __pycache__, etc.)
find . -type d \( -name .git -o -name node_modules -o -name __pycache__ -o -name .venv -o -name target -o -name dist -o -name build \) -prune -o -type d -print

For each directory in scope, record:

  1. Does CLAUDE.md exist?
  2. If yes, does it have the required table-based index structure?
  3. What files/subdirectories exist that need indexing?

Phase 2: Audit

For each directory, check for drift and misplaced content:

<audit_check dir="[path]">
CLAUDE.md exists: [YES/NO]
Has table-based index: [YES/NO]
Files in directory: [list]
Files in index: [list]
Missing from index: [list]
Stale in index (file deleted): [list]
Triggers are task-oriented: [YES/NO/PARTIAL]
Contains misplaced content: [YES/NO] (architecture/design docs that belong in README.md)
README.md exists: [YES/NO]
README.md warranted: [YES/NO] (invisible knowledge present?)
</audit_check>

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

doc-sync is a skill published in the GitHub repository solatis/claude-config (901 stars, last pushed 5mo ago), licensed MIT. It adds 18 tokens to every session and 1,669 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
