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

review-plan 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

Purpose and inputs

Use the attached or in-context plan, the matching implementation, and plan-feature. Stay read-only. Do not create files, branches, or scaffolds.

Steps

  1. Confirm the plan states goals, 3–5 assumptions, References, and ordered slices. Flag missing deferrals for consequential or high-risk items.
  2. For each slice, check that a reviewer can observe the result, that a concrete verification method is named, and that generated outputs name an owning source.
  3. Compare the plan to current code and docs. Call out contradictions, invented commands, and slices that create a branch or scaffold just to plan.
  4. Check dependency order: uncertain work and generated-source ownership come before dependents. Reject a second backlog or overwrite of another unfinished plan.
  5. Reply in chat only: summary, gaps, suggested reorder, and questions. No time estimates.

Verification

  • Each slice has an observable acceptance condition and a named check.
  • Generated sources and consequential unresolved decisions are explicit.
  • The plan does not authorize Git changes or implementation by itself.

Handoff

Return whether the plan is implementable as written, the first blocked slice, and what must change before /build. An inspection is not approval to implement.

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.
