ci-cost-control

Keep GitHub Actions spend down on Meshtastic-Android - avoid redundant runs, cancel superseded ones, and pick the narrowest CI path for the change. Use this whenever you are about to push repeatedly, re-run a workflow, touch `.github/workflows/`, or someone asks why CI is slow, queued or expensive.

Quality

Content

86%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.

The body is highly actionable and token-efficient, delivering repo-specific knowledge (path-filter behavior, cancel-in-progress semantics, drift-guard requirements) alongside exact commands, with local verification and a rerun-failed feedback loop. Its main weaknesses are minor: a redundant Description section that restates the frontmatter and an implicit rather than explicit workflow ordering across the rules.

Suggestions

Remove the "## Description" section, which restates the frontmatter description verbatim in function, and trim rhetorical filler like "Do not waste the tokens or the compute" to push conciseness to a 5.

Make the workflow order explicit — e.g., frame the rules as a sequence (1. check in-progress runs, 2. run the local gradle chain, 3. push, 4. monitor and rerun-failed) so the checkpoints read as an ordered pipeline rather than parallel rules.

Clarify the failure-recovery loop: state that when "gh run view" shows a real (non-flake) failure, the fix should be batched into a single push rather than incremental ones, tying rule 1 and the Monitoring section together.

DimensionReasoningScore

Conciseness

The body is dense with non-obvious repo facts (which workflow has which filter, the exact local command chain) with no explanation of concepts Claude already knows, but the "## Description" section ("Guidelines for agents to minimize GitHub Actions compute waste...") duplicates the frontmatter and "Do not waste the tokens or the compute" is trimmable rhetoric — minor instances, matching anchor 4 rather than the fully lean anchor 5.

4 / 5

Actionability

Fully executable, copy-paste-ready commands cover the common cases: "gh run list --branch $(git branch --show-current) --limit 5", "./gradlew spotlessApply spotlessCheck detekt detektTypeResolved assembleDebug test allTests", and "gh run rerun <run_id> --failed", with explicit conditions for each.

5 / 5

Workflow Clarity

An implied sequence exists (check running CI → validate locally → push → monitor) with real checkpoints (local tests gate the push; "gh run view" then rerun-failed forms a feedback loop), but the rules are presented as parallel numbered rules rather than an explicit ordered workflow — clear sequence with minor gaps, matching anchor 4.

4 / 5

Progressive Disclosure

This is a simple skill under 50 lines with no need for external references (no bundle files exist), and the content is well-organized into Rules and Monitoring sections — per the rubric's simple-skill exception this scores 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.

The description is exemplary: it states concrete capabilities in third person, provides an explicit "Use this whenever..." clause with natural trigger phrases including the workflow-file path, and occupies a distinct niche (GitHub Actions cost control for a specific project). It matches the strongest good_overall_examples in structure and quality.

DimensionReasoningScore

Specificity

"avoid redundant runs, cancel superseded ones, and pick the narrowest CI path for the change" lists multiple concrete actions (prevention, cancellation, path selection) that comprehensively cover the CI-cost niche, matching the anchor-5 example of specific concrete actions with comprehensive coverage.

5 / 5

Completeness

Explicitly answers "what" (avoid redundant runs, cancel superseded ones, pick the narrowest CI path) and "when" ("Use this whenever you are about to push repeatedly, re-run a workflow, touch `.github/workflows/`, or someone asks why CI is slow, queued or expensive") with concrete trigger phrases, matching the anchor-5 example structure.

5 / 5

Trigger Term Quality

Triggers cover natural user phrasing — "push repeatedly", "re-run a workflow", "why CI is slow, queued or expensive" — plus the file-path equivalent ".github/workflows/" and synonyms (slow/queued/expensive), giving comprehensive coverage including synonyms.

5 / 5

Distinctiveness Conflict Risk

Scoped to "GitHub Actions spend down on Meshtastic-Android" with CI-specific triggers — a clear niche with distinct triggers that no other skill would claim, so conflict risk is minimal.
