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

slipway-review 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 12d 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

Slipway Review

Use this capability only for a current Review Action or when the user explicitly invokes it directly. It is always read-only.

For a Run Action, compare the current workspace with the immutable Run-start HEAD and fingerprint. List pre-existing dirty and untracked paths separately. A start-to-current difference is only an observation: concurrent user edits, other Runs, or tools may have contributed, so never claim that the current Run or Implement caused it merely because it appeared later.

Inspect two dimensions:

  1. Intent — missing, partial, incorrect, excessive, or out-of-scope behavior relative to the pinned self-contained Requirements and confirmed decisions.
  2. Quality — design, error handling, concurrency, security, maintainability, and test-sensitive concerns.

Report concrete findings with locations, details, and uncertainties. The strict Run Outcome must carry action_kind: "review" matching the current Action. Submit only these combinations:

  • host completed with review.result no_findings_reported or findings_reported;
  • host partial with review.result inconclusive;
  • host error with review.result error.

Set pause and implementation to JSON null, include every common Outcome field, and leave suggested_actions empty. not_run is reserved for a CLI review-skip projection.

Do not modify files, return needs_input, ask the user to choose a repair, suggest Implement, issue pass/fail or approval language, pause the Run, or create an automatic repair or re-review loop. Findings always flow to Summary; the user may later choose a separate Change or a new Run.

When invoked directly outside a Run, use the baseline named by the user. If none is named, inspect the current workspace against HEAD and state that it is a standalone baseline, not a Run-start snapshot. Return the same factual review without inventing Run attribution or protocol IDs.

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.
