review-severity

review-severity is a skill for Claude Code from Jartan-LLC/grimoire. It costs 35 tokens per session (2,351 once invoked), scanned A, original, MIT.

A shared model for ranking code-review findings as Critical, Important, or Minor according to the likely consequence if shipped and how reachable the problem is. Confidence is assessed separately.

In plain words
What is it for?
Use it to classify security, correctness, crash, data, and reliability findings during code reviews, especially at public APIs, trust boundaries, or persisted state.
Why use it?
It makes review priorities more consistent and prevents severity from being based only on how worrying a problem sounds or how easy it is to fix.

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-severity 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.

Review Severity

Every reviewer tiers findings on one model, so a finding lands the same tier whoever raises it. A tier is earned by a named consequence plus a reachable path -- not by unease, vividness, or how easy it is to fix.

The spine

Severity = consequence-if-shipped = impact x reachability. Confidence is not part of it (separate gate, below).

  • Impact = KIND (corruption / breach / crash / wrong-result / disclosure) x MAGNITUDE (damage per occurrence) x TIME-HORIZON (irreversibility is just long-horizon impact).
  • Reachability = P(path reached) x P(trigger), classed live / edge / dead. Judge it at the trust boundary -- a public/exported API or persisted state is a live entry point even with no in-repo caller; a missing or weakened control on a boundary (authz, rate-limit, crypto strength, secure default) defaults live, its impact being the breach it fails to prevent. And at intended-completion for a diff -- a named wiring/flag/call path is pending-live; only provably unwired code is dead. "I couldn't find the caller" is not dead.

Tiers (directives)

  • Critical -- never ship / regenerate. On a reachable path the code misbehaves or is unsafe above the magnitude floor: data loss/corruption (including silent), security breach, crash/hang/resource-exhaustion, won't build-or-run, broken reference, or a wrong result users/callers/downstream act on ("behaves right" means correct output, not merely "runs"). Also Critical when severe damage is confined to an edge but irreversible -- bounded to three kinds only: (i) silent corruption/loss, (ii) external-contract lock-in (published API/schema/event consumers depend on), (iii) irreversible disclosure (secret/ PII/key that can't be un-leaked). Cost-to-fix never demotes.
  • Important -- avoid; fix by default. Deferral is a conscious, logged, recoverable choice (owner + reason), never silent. Two doors, tagged with a {landmine | debt} sub-label: maintainability-debt -- correct on reachable paths today but a compounding cost a future change must pay (missing tests on load-bearing logic, fragile coupling, drift-prone duplication, a misleading contract); recoverable-latent-landmine -- severe impact whose only reachable path is a genuine recoverable edge (rare input, flag-gated with a named-but-unwired path, an error branch that degrades). Irreversible impact rounds up to Critical, never sits here.
  • Minor -- optional polish, safe to leave. Expected damage ~0 even when reached: cosmetic/preference, comments restating code, micro-optimizations with no measured effect, debug noise, a non-exploitable info leak. A severe defect on demonstrably-dead code (proven no caller, not exported, no named flag path) is Minor -- latent-flagged so it re-tiers the instant a path is wired.

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.

review-severity is a skill published in the GitHub repository Jartan-LLC/grimoire (2 stars, last pushed 4d ago), licensed MIT. It adds 35 tokens to every session and 2,351 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
