sentry-backend-bugs

Review Sentry Python and Django changes for bug patterns drawn from real production issues. Use when reviewing a backend diff or PR, checking Warden findings, auditing the current branch, reviewing production-error patterns, or looking for common regressions in `src/` and `tests/`.

Quality

Content

92%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A high-quality, actionable review skill: concrete named patterns and fixes, a well-gated reporting workflow, and clean progressive disclosure through a reference table. The only slack is a brief motivational intro that adds tokens without aiding execution.

Suggestions

Trim or relocate the production-issue statistics in the opening paragraph ('638 real production issues... 27 million error events... 65,000+ affected users') — they establish credibility but do not help Claude perform the review.

The per-check issue/event counts (e.g. '113 issues, 3,035,640 events') earn their place as prioritization signal, but consider condensing to a single priority order note if token budget is tight.

DimensionReasoningScore

Conciseness

Mostly lean and efficient — it assumes Claude knows Django/ORM/Snuba and stays on concrete red flags and safe patterns — but the opening marketing paragraph ('638 real production issues... 27 million error events... 65,000+ affected users') does not help Claude perform the review and could be trimmed.

4 / 5

Actionability

Fully actionable throughout: named APIs and copy-ready snippets (Model.objects.get(id=some_id), min(value, 2_147_483_647), request.META.get(...), dict.copy() before iteration) cover the common cases.

5 / 5

Workflow Clarity

Clear three-step sequence with confidence-gated reporting (HIGH/MEDIUM only), explicit per-confidence criteria, 'Not a bug — do not flag' false-positive guards, and a 'stop and report zero findings' termination checkpoint.

5 / 5

Progressive Disclosure

Clear overview with a classification table mapping code types to eight real one-level-deep reference files (all verified present), making navigation easy and keeping detail out of the body.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

An exemplary description: third-person voice, concrete capabilities, explicit 'Use when' triggers with synonyms and path references, and a clearly distinct niche. No vague fluff or over-claims.

DimensionReasoningScore

Specificity

Names the Sentry Python/Django backend domain and lists multiple concrete review actions — checking Warden findings, auditing the current branch, reviewing production-error patterns, and looking for regressions — matching the comprehensive-coverage anchor.

5 / 5

Completeness

Explicitly answers both 'what' (review Sentry Python/Django changes for bug patterns from real production issues) and 'when' via a concrete 'Use when...' clause listing multiple trigger scenarios.

5 / 5

Trigger Term Quality

Covers natural terms a reviewer would actually say ('backend diff or PR', 'Warden findings', 'current branch', 'production-error patterns', 'regressions') plus synonyms (diff/PR) and concrete path references (src/, tests/).

5 / 5

Distinctiveness Conflict Risk

Targets a tight Sentry-backend niche with distinct, domain-specific triggers (Warden, production-error patterns), giving it minimal overlap with other skills.
