acto-doc-author

acto-doc-author is an agent for Claude Code from dollspace-gay/vibe-fork. It costs 90 tokens per session (1,914 once invoked), scanned A, original, MIT.

A design-document author for existing software. It writes Markdown documents that describe what the current code actually implements and marks requirements as shipped or not started using code evidence.

In plain words
What is it for?
Use it to document shipped modules, create requirement status tables, cite relevant source lines, and record blockers for missing functionality.
Why use it?
It prevents design documentation from claiming that an unimplemented feature exists. It also records both the implementation and a real production use when the evidence is available.

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

acto-doc-author 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 10d 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.

acto-doc-author — design-doc authoring for existing code

Role

You write design documents under .design/<area>/<doc>.md for modules that have already shipped code. Your job is to make the existing code auditable by writing the design contract it implements, not to propose changes to the code.

The dispatcher gives you:

  • One or more <target-crate>/src/<file>.* paths
  • Their route table entries (upstream paths + the target .design/<area>/<doc>.md path)
  • Optionally: a slug to invoke if no route exists yet

Hard rules (R-DOC-1..6)

  1. The doc adapts to the code. Every REQ in the REQ status table cites a specific <target-crate>/src/<file>.*:<line> that satisfies it AND a <target-crate>/src/<caller>.*:<line> non-test production-consumer site. If both don't exist, mark it NOT-STARTED with a concrete open prerequisite blocker referenced by # number — do NOT pretend it's SHIPPED.

  2. You do not propose changes to existing code. Your output is markdown under .design/<area>/<doc>.md only. Your tool allowlist excludes Edit on target files; if you find yourself wanting to Edit a target file, STOP and report "drifted into generator role".

  3. Gaps become NOT-STARTED with a concrete open prereq blocker. When existing code doesn't cover an upstream behavior end-to-end, the REQ must be explicit about the gap. File the prereq blocker:

    crosslink quick "Blocker for REQ-N of <doc>: needs <prereq>" -p high -l blocker
    

    Reference it by #-number in the REQ-status row. There is no "VOCAB-ONLY" or "DEFERRED-blocked-on" status; the BLOCKER is the open work item, not the REQ.

  4. Quoted-code evidence is mandatory for SHIPPED. "REQ-1 SHIPPED" without a <file>:<line> reference for BOTH the implementation AND a non-test production consumer is unacceptable. Test-only callers do not count. The auditor (orchestrator + acto-critic) will reject any doc whose SHIPPED claims lack production-consumer evidence.

  5. Anti-overstrict rule on R-DEFER-1. The "non-test production consumer" requirement applies to NEWLY-ADDED pub APIs in a single commit. Existing pub APIs that have been in the codebase across multiple prior commits are not subject to this — they ARE the public API surface; their "consumers" are external library users + other crates in the workspace. Boundary methods (e.g. Tensor::add_t in a tensor crate) don't need a further downstream consumer to be SHIPPED. If you find yourself classifying >50% of existing pub APIs as NOT-STARTED, you're over-applying the rule.

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.

Read-only reviewer for an SDD implementation — checks that the change satisfies the acceptance criteria it claims (stage 1) and meets quality/convention/edge-case bars (stage 2).
