debugging-ci-failures

Debugs failing GitHub Actions CI runs for PostHog PRs, commits, and branches, and answers broad CI-health questions ("is CI red?", "is master green today?", "what's broken right now?"). Use when the user asks why CI is red, asks for the current CI or master status, or mentions a failing check, GitHub Actions run, Depot runner, workflow, job, shard, flaky test, lint failure, typecheck failure, snapshot diff, migration check, generated types drift, or skills build failure. Start with the `hogli ci:insights` digest (aggregated cross-run CI intelligence), then guides read-only inspection, failure classification, smallest local reproduction with hogli, and safe reporting without rerunning CI or posting to GitHub.

Quality

Content

92%

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

A highly actionable, well-sequenced triage skill with executable commands and clear validation checkpoints; its only weakness is progressive disclosure, as all content lives inline in a single 174-line file with no referenced detail files.

Suggestions

Extract the Classification table and/or PostHog CI notes into a referenced reference file (e.g. references/classification.md) and link to it one level deep, so SKILL.md stays an overview and progressive disclosure can reach a 3.

Tighten the repeated 'hogli ci:insights is fresher than the gh API because it can lag or rate-limit' rationale, which appears ~3 times (intro, 'Always start with' paragraph, and section 1) — state it once.

Consider a short explicit validation/verification checkpoint before the Report step (e.g. confirm the classified class is consistent with the extracted failing command) to make the workflow's feedback loop fully explicit.

DimensionReasoningScore

Conciseness

Lean, table-and-command dense body that assumes Claude's competence (no explaining of what CI or GitHub Actions is); every section earns its place, though the 'insights is fresher than the gh API / can lag or rate-limit' rationale is restated ~3 times and could be tightened. Still closest to the 'lean and efficient' anchor.

3 / 3

Actionability

Fully executable, copy-paste-ready commands throughout (hogli ci:insights variants, gh pr checks, gh run view --log-failed) plus concrete classification and local-reproduction tables giving exact first actions per class.

3 / 3

Workflow Clarity

Clear numbered sequence (start with insights, then find the failing run) with explicit checkpoints ('Stop at the first failing step'), an error-recovery fallback (insights not installed -> fall back to gh), and a defined handoff (flaky -> fixing-flaky-tests); the skill is read-only triage so the destructive-ops feedback-loop cap does not apply.

3 / 3

Progressive Disclosure

Well-sectioned (Safety rules, Workflow, Classification, Local reproduction, PostHog CI notes, Report shape) but it is a ~174-line monolith with an empty bundle and no one-level-deep references to split material into; over the 50-line simple-skill threshold, so it does not meet the 'well-signaled one-level-deep references; content appropriately split' bar for a 3.

Description

100%

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

A strong, third-person description with explicit 'Use when' triggers, comprehensive natural trigger terms, and a distinct PostHog-CI-triage niche. It clearly answers both what the skill does and when to invoke it.

DimensionReasoningScore

Specificity

Uses third person ('Debugs failing GitHub Actions CI runs', 'answers broad CI-health questions', 'guides read-only inspection, failure classification, smallest local reproduction') and lists multiple concrete actions, matching the 'lists multiple specific concrete actions' anchor.

3 / 3

Completeness

Explicitly answers both 'what' (debugs/triages CI failures and answers CI-health questions) and 'when' via an explicit 'Use when the user asks why CI is red...' trigger clause.

3 / 3

Trigger Term Quality

Natural phrasing a user would actually say ('is CI red?', 'is master green today?', 'what's broken right now?') plus broad coverage (failing check, GitHub Actions run, Depot runner, workflow/job/shard, flaky test, lint/typecheck/snapshot/migration drift).

3 / 3

Distinctiveness Conflict Risk

Clearly niched to PostHog CI failure triage with distinct triggers (Depot runner, shard, snapshot diff, generated types drift); unlikely to fire for unrelated skills despite a minor overlap on 'flaky test' with the fixing-flaky-tests skill.
