documentation-synchronizer

A process for keeping documentation aligned with changes to software, APIs, settings, data formats, interfaces, deployments, and operations.

In plain words
What is it for?
Use it to map a code change to affected documentation, update the relevant sources, and check the result against current behavior.
Why use it?
It finds outdated instructions, examples, screenshots, links, and generated documentation after behavior or contracts change.

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

documentation-synchronizer 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/doc_drift_scan.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 Synchronizer

Treat documentation as a distributed contract with users, developers, operators, and integrators.

Trigger boundary

Use this skill for:

  • identifying docs affected by an implementation or migration diff;
  • synchronizing user guides, API references, configuration, examples, architecture, runbooks, and release notes;
  • auditing stale commands, options, screenshots, generated docs, or cross-links;
  • verifying a documentation-only change against current code and public contracts.

Do not trigger for:

  • deciding what the product should do;
  • visual brand/campaign copy unrelated to repository behavior;
  • a code change with no externally or operationally meaningful documentation surface;
  • generating API docs by editing generated output instead of its source.

Required inputs

Obtain:

  1. changed files/diff and final intended behavior;
  2. repository documentation map and audience/release context;
  3. authoritative sources for APIs, schemas, config, CLI, environment, and defaults;
  4. supported versions and migration/deprecation policy;
  5. documentation tooling, generators, link/check commands, and localization policy;
  6. known generated, translated, versioned, or externally hosted documentation boundaries.

If behavior is ambiguous, stop and return the exact implementation question. Do not resolve ambiguity through prose.

Safety baseline

  • Inspect worktree state and preserve unrelated edits.
  • Do not rewrite all docs to normalize style; update only impacted surfaces and necessary consistency links.
  • Do not edit generated docs directly unless the repository explicitly treats them as source.
  • Never copy secrets, production identifiers, private URLs, or personal data into examples.
  • Mark destructive examples clearly and provide safe prerequisites; do not invent executable commands.
  • Keep version-specific instructions scoped and dated where they can become stale.

Workflow

1. Extract the contract delta

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.

documentation-synchronizer is a skill published in the GitHub repository cmdr-chara/codex-toolkit (2 stars, last pushed 4d ago), licensed MIT. It adds 73 tokens to every session and 1,635 once invoked, about $0.0004 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 2026-08-31.
