doc-sync

A documentation synchronization routine that finds differences between project documents and code, drafts corrections, and shows them for approval.

In plain words
What is it for?
Use it for a full documentation sweep or to limit the check by change reference or document type. It can update design, memory, integration-boundary, and rules documents, but does not modify code or commit changes automatically.
Why use it?
It helps bring outdated documentation back in line with the code while keeping the developer in control of which changes are applied.

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

Respond in the user's preferred language (detect from their recent messages, or fall back to the language setting in CLAUDE.md).

Local, on-demand documentation synchronization. This is the third trigger mode for doc maintenance, complementing the event-driven layer (pre-commit warn) and the scheduled layer (periodic report): the human runs it when they know they've changed something doc-affecting, to pull drifted docs back in line with the code — but the human keeps the landing authority.

Relationship to qq:doc-drift: doc-drift is report-only (it outputs a P0/P1/P2 attention list). doc-sync is the reconcile loop — it calls doc-drift (and the project's drift detectors) as its detection stage, then adds the two stages doc-drift lacks: draft the fixes and land what the human approves.

Arguments: $ARGUMENTS

  • No arguments: full sweep of the project's living docs
  • --since <ref>: only docs affected by code changed since <ref> (windowed reconcile)
  • --scope <design|memory|seams|rules>: restrict to one class of living doc
  • --all: include archived/historical docs (default excludes Docs/archive/ and old review artifacts)

Principle (do not violate)

Detectors are read-only; doc-sync is the sole writer; the human is the sole lander. Reference drift (a dead anchor) is auto-drafted; semantic/process drift is only flagged for the human to decide. Graphs say "what is wired now"; the seam registry says "what should be wired / what breaks if missing" — neither overwrites the other.

Execution Flow

1. Discover the project's drift tooling (project-aware)

Probe for these and use whatever exists — degrade gracefully when absent (a generic project just gets doc-drift + git-diff reasoning):

If present Use it for
Tools/blast_radius.py "changed files → affected docs + code-side ripple" (diff [base] / who <token>)
Tools/check_doc_drift.py symbol-anchor drift in docs (LINEREF / missing file / missing GUID / 0-hit symbol)
Tools/check_memory.py memory consistency + staleness (audit); re-stamp via stamp <date> <files>
Tools/check_seams.py .claude/seams.yml anchor drift
.claude/seams.yml cross-cutting seam registry (fan-out points)

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 tykisgod/quick-question (11 stars, last pushed 8d ago), licensed MIT. It adds 66 tokens to every session and 1,709 once invoked, about $0.0003 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.
