ferrox-docs-update

ferrox-docs-update is a skill for Claude Code from FerroxLabs/ferrox-factory. It costs 19 tokens per session (509 once invoked), scanned A, original, MIT.

A documentation workflow that writes or refreshes project documentation and checks it against the actual code.

What is it for?
It helps generate docs, preserve or replace existing content, and verify documentation without writing changes.
Why use it?
It reduces the risk that documentation becomes outdated or describes behavior the project does not have.

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

ferrox-docs-update 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.

What it actually says

Flag handling rule:

  • The optional flags documented below are available behaviors, not implied active behaviors
  • A flag is active only when its literal token appears in $ARGUMENTS
  • If a documented flag is absent from $ARGUMENTS, treat it as inactive
  • --force: skip preservation prompts, regenerate all docs regardless of existing content or Ferrox markers
  • --verify-only: check existing docs for accuracy against codebase, no generation (full verification requires Phase 4 verifier)
  • If --force and --verify-only both appear in $ARGUMENTS, --force takes precedence

<execution_context> @~/.claude/ferrox-core/workflows/docs-update.md </execution_context>

Available optional flags (documentation only — not automatically active):

  • --force — Regenerate all docs. Overwrites hand-written and Ferrox docs alike. No preservation prompts.
  • --verify-only — Check existing docs for accuracy against the codebase. No files are written. Reports VERIFY marker count. Full codebase fact-checking requires the ferrox-doc-verifier agent (Phase 4).

Active flags must be derived from $ARGUMENTS:

  • --force is active only if the literal --force token is present in $ARGUMENTS
  • --verify-only is active only if the literal --verify-only token is present in $ARGUMENTS
  • If neither token appears, run the standard full-phase generation flow
  • Do not infer that a flag is active just because it is documented in this prompt
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.
