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

diff-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 1mo 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

diff-review

Estelle's PR-review skill. Two independent axes so nothing slips through.

Procedure

  1. Standards axis — does the diff follow the repo's learned conventions (naming, types, docstrings, errors, tests, immutability)? Use the convention profile.
  2. Spec axis — does it actually do what the originating issue/PRD asked? Check against the spec, not vibes.
  3. Gate axis — run the deterministic grounding gate (no invented APIs), the security scan (secrets / CVE / SAST — see threat-scan), and license/provenance. Place every finding as an inline comment on its exact line.
  4. Summarize: blockers (CRITICAL/HIGH) vs suggestions (MEDIUM/LOW); approve only when no blockers remain.

Output

An inline review comment stream + a merge verdict. Serves every PR; the swarm's reviewer agents run this.

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.
