exploring-endpoint-execution-logs

Explore and diagnose a PostHog endpoint's execution logs — error messages, failed runs, cache misses, slow runs, or unexpected row counts during endpoint invocations. Use when the user says "my endpoint is failing", "show me the logs for endpoint X", "what error did endpoint Y produce", "why did endpoint Z return no rows", "is this endpoint hitting cache", or "check the last N runs". Focused on a single named endpoint's runtime log entries, not project-wide auditing or query performance profiling.

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.

A tightly written, highly actionable diagnostic skill that conveys genuine domain knowledge Claude would not already have, with only minor gaps in formal validation checkpoints and no need for external reference files.

Suggestions

Add an explicit verification step to the workflow (e.g. cross-check the failing run count against the endpoint's INFO runs or expected schedule before summarizing) to close the validation gap and push workflow_clarity to 5.

Consider splitting the token-meanings and tool-capability tables into a short reference section or file if the skill grows, to keep the overview scannable.

DimensionReasoningScore

Conciseness

Lean and dense with non-obvious domain specifics (token table, log_source_id UUID quirk, 90-day TTL, best-effort emission); it assumes Claude's competence and avoids explaining concepts Claude already knows, so every section earns its place.

5 / 5

Actionability

Provides concrete tool names with filter values, a copy-paste-ready SQL aggregation query, and a worked example interaction with exact tool calls — fully executable guidance covering the common diagnostic cases.

5 / 5

Workflow Clarity

Clear numbered sequence (identify → start broad → narrow by symptom with branches → drop to SQL for aggregates → summarize) but lacks an explicit validation/verification checkpoint confirming a finding before synthesis, so it sits just below the top anchor.

4 / 5

Progressive Disclosure

Well-organized into clear sections (When to use, entry format, tools, filtering, workflow, example, notes) with content appropriately placed and no material that clearly belongs in a separate file, though no one-level-deep reference structure is present because none is needed.

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 exemplar description: concrete actions, abundant natural trigger phrases, explicit what-and-when, and a sharp boundary against sibling skills, all in third-person imperative voice.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'Explore and diagnose', 'error messages, failed runs, cache misses, slow runs, or unexpected row counts' — for a named domain (PostHog endpoint execution logs), giving comprehensive coverage rather than generic verbs.

5 / 5

Completeness

Explicitly answers what ('Explore and diagnose a PostHog endpoint's execution logs — error messages, failed runs...') and when ('Use when the user says...') with concrete trigger phrases, satisfying the top anchor on both axes.

5 / 5

Trigger Term Quality

Six quoted natural phrases users would actually say ('my endpoint is failing', 'show me the logs for endpoint X', 'why did endpoint Z return no rows', 'is this endpoint hitting cache', 'check the last N runs') give comprehensive coverage of natural trigger terms.

5 / 5

Distinctiveness Conflict Risk

Scoped to 'a single named endpoint's runtime log entries' and explicitly excluded from 'project-wide auditing or query performance profiling', carving a clear niche with minimal overlap risk.
