repomix-explorer

Analyze or explore a codebase (remote or local repository) by packing it with the Repomix CLI, then reading and searching the generated output. Use when the user wants a high-level understanding of an unfamiliar or large repo, not a targeted edit. Trigger for: - Structure/overview: "analyze this repo", "what's the structure", "explain this codebase", "what's in vercel/next.js" - Pattern discovery across many files: "find all auth code", "where are the API endpoints", "show me all React components" - Metrics: "how many files/tokens", "largest files", "TypeScript vs JavaScript ratio" - Remote repos: any github.com URL or "owner/repo" the user wants explored DO NOT trigger for: - Editing, refactoring, or writing code in the current project - Reading or searching a known file/path in the local project (use Read or grep directly) - Single-symbol lookups in the local project answerable with one grep - Git operations, running tests, builds, or installs

Quality

Content

56%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 skill body delivers concrete, executable repomix commands and a coherent four-step workflow with error-recovery guidance, but it is noticeably padded and monolithic. Roughly half the file (intent examples, communication style, generic grep recipes, self-verification checklist) duplicates what Claude already knows and should be trimmed or moved to reference files.

Suggestions

Cut the 'User Intent Examples', 'Communication Style', and 'Self-Verification Checklist' sections — they restate the description's triggers and generic behavior Claude already follows, and they drive the conciseness score down.

Move the 'Search Patterns' grep catalog and the five 'Example Workflows' into a single references/ file (e.g. references/patterns.md) and link to it from a short 'Workflow' section, so SKILL.md stays a lean overview.

Add an explicit validation checkpoint in Step 1/Step 2: confirm the repomix command's exit status and that the output file exists (e.g. test -f /tmp/<repo>-analysis.xml) before grepping or reading it, upgrading the workflow from implicit to explicit validation.

DimensionReasoningScore

Conciseness

Several padded sections restate what Claude already knows: the role preamble 'You are an expert code analyst...', ~20 'User Intent Examples' that duplicate the description's triggers, 'Your Responsibilities' items like 'Understand the user's intent from natural language', a 'Communication Style' section advising 'Be concise but comprehensive' and 'Cite sources', generic grep recipes ('grep -iE "error|exception|try.*catch"'), and an 11-item 'Self-Verification Checklist' ('Did you communicate clearly and concisely?'). This matches the 'noticeably verbose; several unnecessary explanations or padded sections' anchor; not 1 because the core command/flag material is genuinely useful and not conceptual filler.

2 / 5

Actionability

Concrete, executable commands throughout: 'npx repomix@latest --remote yamadashy/repomix --output /tmp/repomix-analysis.xml', a flags table ('--compress', '--include "**/*.{ts,tsx}"', '--remote-branch'), and runnable greps. Not 5 because some guidance remains narrative (Example Workflow steps like 'Summarize: "This repository contains [number] files..."' and 'Provide structural overview with ASCII diagram if helpful') rather than copy-paste-ready instructions, leaving minor gaps.

4 / 5

Workflow Clarity

A clear four-step sequence (Pack the Repository -> Check Command Output -> Analyze the Output File -> Provide Insights) with an Error Handling section providing feedback loops ('Command fails' -> verify URL/path/permissions; 'Pattern not found' -> 'Try alternative patterns', 'Suggest broader search'). Not 5 because there is no explicit validation that the pack command actually succeeded (exit status / output file exists) before proceeding to grep, and the Self-Verification Checklist is stylistic self-assessment rather than an operational checkpoint; not 3 because recovery loops and a mid-workflow output check are present.

4 / 5

Progressive Disclosure

The body has good section headers but is a single ~295-line monolith with no references/ or other bundle files at all: content that clearly belongs in separate files is inlined, such as the 'Search Patterns' recipe catalog, five full 'Example Workflows', and the long intent-example lists. This matches the anchor 'content that should be separate is inline' while structure is present; not 4 because essentially all bulk detail lives in SKILL.md rather than being offloaded to well-signaled reference files.

Description

95%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 a strong, complete example: it states exactly what the skill does (pack with Repomix CLI, then read/search the output), when to use it, and when not to, using natural trigger phrases in third-person voice. Minor headroom remains only in enumerating a slightly broader set of concrete actions.

DimensionReasoningScore

Specificity

Quotes: 'Analyze or explore a codebase (remote or local repository) by packing it with the Repomix CLI, then reading and searching the generated output' — names the concrete tool and several specific actions (pack, read, search) plus concrete analysis categories ('find all auth code', 'TypeScript vs JavaScript ratio'). Not 5 because it stops short of a comprehensive action list (e.g., compression, metrics reporting, cleanup are never stated); not 3 because it goes beyond 1-2 generic actions by naming the exact CLI and the output-analysis mechanism.

4 / 5

Completeness

The 'what' is explicit ('packing it with the Repomix CLI, then reading and searching the generated output') and the 'when' is explicit ('Use when the user wants a high-level understanding of an unfamiliar or large repo, not a targeted edit') plus enumerated Trigger for / DO NOT trigger for lists. Both are answered clearly with concrete trigger phrases, matching the top anchor; it cannot be 4 because the 'when' is not merely adequate but exhaustively specified with positive and negative triggers.

5 / 5

Trigger Term Quality

Quotes: "analyze this repo", "what's the structure", "explain this codebase", "find all auth code", "where are the API endpoints", "show me all React components", "how many files/tokens", "largest files", "TypeScript vs JavaScript ratio", plus 'any github.com URL or "owner/repo"'. This is comprehensive natural-phrase coverage with synonyms and URL forms, matching the top anchor; nothing common is missing.

5 / 5

Distinctiveness Conflict Risk

Clear niche (whole-repo packing and exploration via Repomix) with actively disambiguating negative triggers: 'Editing, refactoring, or writing code', 'Reading or searching a known file/path in the local project (use Read or grep directly)', 'Single-symbol lookups... answerable with one grep', 'Git operations, running tests, builds, or installs'. These explicit carve-outs keep conflict risk minimal, matching the top anchor.
