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 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.

Review Skill

Run a full expert code review before merging.

When to use

  • Before opening or merging a PR/MR
  • When asked to review code
  • After implementing a significant feature

Protocol

1. Gather the diff

git --no-pager diff main...HEAD | head -500

Or specify a branch: git --no-pager diff <base>...<head> | head -500

2. Read context

  • claude/templates.md for PR template requirements
  • claude/rules.md for project-specific rules

3. Spawn reviewer subagent (recommended for isolation)

"Spawn a reviewer subagent to review this PR. Diff: [paste diff]. Focus on the 10-point protocol."

4. Or: Self-review with the 10-point protocol

Point 1 — Ticket re-read: Does every scenario in the ticket/task get addressed?

Point 2 — Cross-layer consistency: Grep every new field name, type, enum across ALL layers:

grep -rn --color=never '<new_field_name>' . | head -50

Point 3 — Enum completeness: Are all enum values handled in every switch/if-chain?

Point 4 — Transaction safety: Are there external calls (HTTP, queue, email) inside DB transactions? → Move them outside.

Point 5 — Race conditions: Is there shared mutable state accessed concurrently without synchronization?

Point 6 — Test coverage: Every new branch/case/error path has a dedicated test?

Point 7 — Pre-existing vs. introduced: Run lint before and after. Distinguish new warnings from pre-existing ones.

Point 8 — Cross-branch merge safety: Will this still apply cleanly after other pending branches merge?

Point 9 — Security: New HTTP calls? Data exposed? New permissions? Unsafe defaults?

Point 10 — Confidence gate: Overall confidence 0-100. Only proceed to PR description if ≥95.

5. Output the review

Report format:

  • Verdict: PASS / FAIL / NEEDS WORK
  • Confidence: X/100
  • Blocking issues (must fix)
  • Advisory suggestions (non-blocking)

6. If passing: generate PR description

Use /mr skill after the review passes.

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.
