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.

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

The skill is highly actionable with a real bundled script and clean reference structure, but the body is longer than it needs to be due to repeated examples and overlapping sections, and its validation workflow lacks a structured feedback loop for a batch file-writing operation.

Suggestions

Collapse the three near-identical use cases into one example plus a short list of variations, and remove the duplication between "What the Script Does" and the Resources script description.

Merge the overlapping "Important Principles" and "Best Practices" sections to cut redundant guidance on temp directories and file-count verification.

Add an explicit validate→fix→retry feedback loop to the Validation Workflow (e.g., if the file count or structure check fails, diagnose via the Troubleshooting section and re-run) to earn full workflow-clarity credit for this batch operation.

Dimension	Reasoning	Score
Conciseness	The 310-line body is padded: three use cases re-run the same command with different paths, "What the Script Does" duplicates the Resources script description, and "Important Principles" overlaps "Best Practices". It is mostly actionable rather than abstract, so it sits above score 1 but does not earn the lean score-3 anchor.	2 / 3
Actionability	Fully executable `python3 scripts/unmix_repomix.py "<input>" "<output>"` commands with parameters and copy-paste examples, a real bundled script, and concrete troubleshooting fixes match the copy-paste-ready anchor.	3 / 3
Workflow Clarity	There is a clear extract-then-validate sequence with a Validation Workflow section and a temp-first safety checkpoint, but no explicit validate→fix→retry feedback loop; per the batch-operation scoring note this caps workflow clarity at 2 rather than 3.	2 / 3
Progressive Disclosure	The body is a clear overview with well-signaled one-level-deep references ("Refer to references/repomix-format.md", "Refer to references/validation-workflow.md"), both of which exist as real bundle files, plus a Resources section for navigation.	3 / 3
	Total	10 / 12 Passed

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.

The description is concise, third-person, specific, and clearly separates what the skill does from when to activate it. It hits all four anchors at the top level with no vague fluff or over-claims.

Dimension	Reasoning	Score
Specificity	"Extracts files from repomix-packed repositories, restoring original directory structures from XML/Markdown/JSON formats" lists multiple specific concrete actions (extract, restore structure, three named formats), matching the multiple-concrete-actions anchor.	3 / 3
Completeness	It states both the what ("Extracts files… restoring original directory structures") and an explicit when ("Activates when users need to…"), satisfying the explicit-triggers anchor.	3 / 3
Trigger Term Quality	"unmix repomix files, extract packed repositories, restore file structures from repomix output, or reverse the repomix packing process" gives good coverage of natural terms a user would say, not jargon.	3 / 3
Distinctiveness Conflict Risk	Repomix is a clear niche and the triggers are specific to repomix output, making it unlikely to fire for unrelated skills.	3 / 3
	Total	12 / 12 Passed
