observability-triage

Triage OpenSEO production errors in Cloudflare Workers Observability — verified query recipes, counting gotchas, a known-noise filter list applied automatically, and the on-demand CPU/heap profiling recipe. Use when asked to review Cloudflare logs/observability, count OOMs or worker errors, compare error rates between periods, investigate a prod error spike, or find where a worker spends CPU or memory (profiles, flamegraphs).

Quality

Content

90%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.

An unusually dense, high-value operational skill: executable query shapes, exact commands, and verified API quirks with no filler, plus real verification checkpoints. The only weaknesses are structural — the triage flow is implied by section order rather than an explicit sequence, and a meaningful share of detail (profiling recipe, noise catalog) is inlined in SKILL.md rather than split into reference files.

Suggestions

Frame the main triage flow as an explicit ordered sequence (access → query → count → interpret → profile if needed) with numbered steps, so the existing checkpoints (litmus test, $workers.scriptVersion check, capture-repeat rule) become explicit validation gates.

Move the per-entry known-noise details (fingerprints, identify-by markers, why-unfixable explanations) into a references/known-noise.md file, keeping in SKILL.md only the auto-apply summary, the runtime-vs-app litmus test, and each entry's one-line real-signal condition.

Consolidate the profiling section's capture → read → interpret steps into a single checklist that ends with the validation step ('repeat a capture before trusting a small frame; convert a hot frame's share into ms against the route's mean before acting').

DimensionReasoningScore

Conciseness

Every line carries non-generic, hard-won operational knowledge ('Grouped results are unsorted and effectively capped (~10 rows returned regardless of `limit`)', 'A heap profile shows allocations made during the window... it finds churn, not leaks') with zero padding and no explanation of concepts Claude already knows. It assumes competence throughout.

5 / 5

Actionability

Fully executable: a complete verified JSON query body, exact CLI commands ('cf workers versions profile latest --worker-id open-seo --duration-ms 10000 --profile-type cpu'), API endpoints, and a real script invocation (node .agents/skills/observability-triage/scripts/pprof-top.mjs, which exists in the bundle). The only placeholder (from/to timestamps) is explicitly annotated as epoch milliseconds.

5 / 5

Workflow Clarity

Genuine validation checkpoints are present (the runtime-vs-app litmus test, 'Check `$workers.scriptVersion`... before concluding a fix didn't work', 'repeat a capture before trusting a small frame'), but the body is organized as a topical playbook (access / recipes / gotchas / profiling / noise) rather than an explicit sequenced workflow with feedback loops — fitting anchor 4 more than the numbered-workflow-with-recovery of anchor 5.

4 / 5

Progressive Disclosure

The single bundle reference (scripts/pprof-top.mjs) is real, one level deep, and well-signaled at its point of use, and sections are clearly headed. However, the ~95-line body inlines substantial detail — the full profiling recipe and the complete known-noise entry catalog with fingerprints — that could partly live in reference files, and no references/ directory exists; anchor 4 ('most content appropriately placed, minor organization gaps') fits better than anchor 5.

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: it names a precise niche, enumerates concrete capabilities, and provides an explicit, naturally-phrased 'Use when' trigger list with synonyms. Both the what and the when are answered clearly and concretely.

DimensionReasoningScore

Specificity

Lists multiple concrete, specific actions — 'count OOMs or worker errors, compare error rates between periods, investigate a prod error spike, or find where a worker spends CPU or memory' plus the named capability components ('verified query recipes, counting gotchas, a known-noise filter list applied automatically, and the on-demand CPU/heap profiling recipe'). Coverage of the skill's actions is comprehensive, matching the anchor-5 example rather than the 'minor gaps' of anchor 4.

5 / 5

Completeness

Explicitly answers both questions: the 'what' is the first sentence (triage prod errors with query recipes, counting gotchas, noise filtering, profiling) and the 'when' is an explicit 'Use when asked to...' clause with concrete trigger phrases — the same structure as the anchor-5 example.

5 / 5

Trigger Term Quality

Natural phrases a user would actually say with synonym coverage: 'review Cloudflare logs/observability', 'count OOMs or worker errors', 'compare error rates between periods', 'investigate a prod error spike', 'profiles, flamegraphs'. Matches the comprehensive-with-synonyms anchor; nothing significant is missing.

5 / 5

Distinctiveness Conflict Risk

'Triage OpenSEO production errors in Cloudflare Workers Observability' carves out a clear niche with distinct triggers (OOMs, error spikes, flamegraphs); minimal to no overlap risk with generic logging or observability skills.
