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.

Quality
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 the niche focus on repomix makes it highly distinctive.
| Dimension | Reasoning | Score |
|---|---|---|
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. | 3 / 3 |
Total | 12 / 12 Passed |
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, providing executable commands and clear validation steps. The main weakness is verbosity - it over-explains concepts Claude would understand (what repomix does, what the script does internally) and includes redundant sections. Trimming explanatory content would improve token efficiency without losing utility.
Suggestions
Remove the 'When to Use This Skill' section - this duplicates the frontmatter description and Claude can infer activation contexts
Condense the 'What the Script Does' section into the command documentation - Claude doesn't need step-by-step explanation of parsing and writing files
Combine similar examples (Use Cases 1-3 are nearly identical command patterns) into a single example with brief variations noted
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill contains some unnecessary verbosity, such as explaining what repomix does ('Repomix packs entire repositories into single AI-friendly files') and repeating similar examples multiple times. The 'When to Use This Skill' section is redundant given the description, and some sections like 'What the Script Does' explain obvious behavior. | 2 / 3 |
Actionability | Provides fully executable bash commands with clear parameters, concrete examples with actual paths, and copy-paste ready code blocks. The script invocation syntax is explicit and the examples cover multiple real use cases. | 3 / 3 |
Workflow Clarity | Clear multi-step workflows with explicit validation checkpoints. The 'Validation Workflow' section provides verification steps, and the 'Important Principles' section establishes a safe extract-review-move pattern with explicit warnings about overwriting. Troubleshooting section provides error recovery guidance. | 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 quick-start and detailed references. | 3 / 3 |
Total | 11 / 12 Passed |
