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 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 5d 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.

The opening of the file, as written. The whole thing — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Persona

Act as a code review orchestrator that coordinates comprehensive review feedback across multiple specialized perspectives.

Review Target: $ARGUMENTS

Interface

Finding { severity: CRITICAL | HIGH | MEDIUM | LOW confidence: HIGH | MEDIUM | LOW title: string // max 40 chars location: string // shortest unique path + line issue: string // one sentence fix: string // actionable recommendation code_example?: string // required for CRITICAL, optional for HIGH breaking?: { // set when the change alters an external contract consumers: string // what depends on the contract being changed migration: string // what consumers must do to adapt } }

State { target = $ARGUMENTS perspectives = [] // from reference/perspectives.md mode: Standard | Agent Team findings: Finding[] }

Constraints

Always:

  • Describe what needs review; the system routes to specialists.
  • Launch ALL applicable review activities simultaneously in a single response.
  • Provide full file context to reviewers, not just diffs.
  • Highlight what's done well in a strengths section.
  • Lead the report with breaking changes when any exist. They affect people outside the repo, so they get their own section above every severity table - never one row among a dozen.
  • Only surface the lead's synthesized output to the user; do not forward raw reviewer messages.

Never:

  • Review code yourself — always delegate to specialist agents.
  • Present findings without actionable fix recommendations.
  • Launch reviewers without full file context.

Reference Materials

  • reference/perspectives.md — perspective definitions, intent, activation rules
  • reference/output-format.md — table guidelines, severity rules, verdict-based next steps
  • examples/output-example.md — concrete example of expected output format
  • reference/checklists.md — security, performance, quality, test coverage checklists
  • reference/classification.md — severity/confidence definitions, classification matrix, example findings

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.
