repomix-unmixer

Extracts files from repomix-packed repositories, restoring original directory structures from XML/Markdown/JSON formats. Activates when users need to unmix repomix files, extract packed repositories, restore file structures from repomix output, or reverse the repomix packing process.

Discovery

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.

This is an excellent skill description that clearly defines a specific capability (extracting and restoring files from repomix-packed repositories), uses natural trigger terms users would actually say, and explicitly states when to activate. The description is well-structured with both capability and trigger information, and targets a distinct niche that won't conflict with other skills.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: 'Extracts files', 'restoring original directory structures', and specifies formats 'XML/Markdown/JSON formats'. These are concrete, actionable capabilities.

3 / 3

Completeness

Clearly answers both what ('Extracts files from repomix-packed repositories, restoring original directory structures from XML/Markdown/JSON formats') AND when ('Activates when users need to unmix repomix files, extract packed repositories, restore file structures from repomix output, or reverse the repomix packing process').

3 / 3

Trigger Term Quality

Excellent coverage of natural terms users would say: 'repomix', 'unmix repomix files', 'extract packed repositories', 'restore file structures', 'repomix output', 'reverse the repomix packing process'. These are terms users would naturally use when needing this functionality.

3 / 3

Distinctiveness Conflict Risk

Very clear niche focused specifically on repomix files. The term 'repomix' is distinctive and unlikely to conflict with other skills. The specific use case of unpacking/reversing repomix output is unique.

Implementation

85%

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

This is a well-structured skill with excellent actionability and workflow clarity. The main weakness is some verbosity in explanatory sections that Claude doesn't need (explaining what repomix is, listing activation triggers). The progressive disclosure and validation workflows are exemplary.

Suggestions

Remove or significantly condense the 'When to Use This Skill' section - this metadata belongs in frontmatter triggers, not the body

Trim the overview paragraph - Claude doesn't need explanation of what repomix does, just how to unmix it

DimensionReasoningScore

Conciseness

The skill contains some unnecessary verbosity, such as explaining what repomix does ('Repomix packs entire repositories into single AI-friendly files') and overly detailed 'When to Use This Skill' section. The troubleshooting section is thorough but could be more concise.

2 / 3

Actionability

Provides fully executable bash commands with clear parameters, concrete examples with actual paths, and copy-paste ready code blocks. The script usage is well-documented with specific examples.

3 / 3

Workflow Clarity

Clear multi-step workflows with explicit validation checkpoints. The 'Validation Workflow' section provides numbered steps, and the 'Important Principles' section includes feedback loops (extract to temp, review, then move). Destructive operations are properly guarded.

3 / 3

Progressive Disclosure

Well-structured with clear overview, core workflow, use cases, and troubleshooting sections. References to external files (repomix-format.md, validation-workflow.md) are clearly signaled and one level deep. Content is appropriately split between main skill and reference files.
