break-loop

Deep post-fix bug analysis across five dimensions: root cause categorization, fix failure analysis, prevention mechanisms, systematic expansion, and knowledge capture. Updates .trellis/spec/ guides with lessons learned to prevent recurring bugs. Use when a debugging session completes, after fixing a tricky bug, when the same class of bug keeps recurring, or when you want to capture debugging insights into project documentation.

Quality

Content

68%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 well-structured, actionable analysis framework whose tables, output template, and named file targets give Claude concrete direction. The main weakness is the post-analysis workflow: the batch spec updates and commit proceed with no validation or verification steps, and a few checklist items remain vague.

Suggestions

Add validation checkpoints to the 'After Analysis' workflow: verify the target guide file exists before editing, review the git diff of spec changes, and confirm the template sync actually copied the updated files before committing.

Make vague checklist items concrete — replace 'Update check skills if needed' and 'Create issue record (if applicable)' with specific locations, formats, and decision criteria for when each applies.

Trim the 'Core Philosophy' section to the single guiding quote and remove the intro sentence that duplicates the description, saving tokens without losing guidance.

DimensionReasoningScore

Conciseness

The body is dominated by dense, instructive tables and checklists that earn their tokens, assuming Claude's competence throughout. Minor over-explanation could be trimmed: the 'Core Philosophy' section ('30 minutes of analysis saves 30 hours of future debugging', the three-levels list) is motivational padding, and the intro line restates the description's trigger.

4 / 5

Actionability

Guidance is mostly concrete and executable for an instruction-only skill: a full output-format template, category tables with examples, and specific file targets ('cross-layer-thinking-guide.md', 'sync to src/templates/markdown/spec/'). Minor gaps remain, e.g. 'Update check skills if needed' and 'Create issue record (if applicable)' give no location, format, or criteria.

4 / 5

Workflow Clarity

The sequence is present and ordered (analyze 5 dimensions, emit the formatted output, update guides, sync templates, commit), but there are no validation checkpoints anywhere: no check that a target guide file exists before editing, no diff review before 'Commit the spec updates', and no verify step after syncing. Since the immediate actions batch-update multiple spec files and commit, the missing feedback loop caps this at 3.

3 / 5

Progressive Disclosure

The skill is a single well-organized file with clear section headers (Analysis Framework, Output Format, Immediate Actions) and compact tables; nothing clearly belongs in a separate reference file. It does not earn a 5 because the under-50-line exception does not apply (~125 lines) and the .trellis path references are operational targets rather than well-signaled bundle references.

Description

83%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.

A strong description that explicitly states what the skill does (five named analysis dimensions plus spec updates) and when to use it, with natural trigger phrasing. Its only flaws are a second-person trigger clause ('when you want to capture debugging insights') and a few missing synonyms like 'postmortem' that keep trigger coverage from being comprehensive.

DimensionReasoningScore

Specificity

The description enumerates five concrete analysis dimensions ('root cause categorization, fix failure analysis, prevention mechanisms, systematic expansion, and knowledge capture') plus a concrete artifact ('Updates .trellis/spec/ guides with lessons learned'), which is comprehensive coverage matching the 5 anchor. However, the trigger clause 'when you want to capture debugging insights' uses second-person voice, incurring the mandated 1-point penalty.

4 / 5

Completeness

It clearly answers both questions: the 'what' is explicit ('Deep post-fix bug analysis across five dimensions... Updates .trellis/spec/ guides') and the 'when' is explicit with concrete trigger phrases ('Use when a debugging session completes, after fixing a tricky bug, when the same class of bug keeps recurring'). This matches the 5 anchor exactly.

5 / 5

Trigger Term Quality

Natural user phrases are present ('a debugging session completes', 'after fixing a tricky bug', 'the same class of bug keeps recurring'), giving good keyword coverage. A few natural terms users would say are missing, such as 'postmortem', 'retrospective', or 'root cause analysis', so it does not reach comprehensive synonym coverage.

4 / 5

Distinctiveness Conflict Risk

The post-fix retrospective niche is mostly distinct with a clear temporal boundary ('Use when a debugging session completes'). Minor overlap risk remains with general debugging skills via 'when the same class of bug keeps recurring', which a user might also say mid-debugging, so it sits between the 4 and 5 anchors.
