Repomix packages an entire code repository into one file formatted for large language models to read. Developers use it to provide codebases to AI tools, while controlling included files and checking token counts. Catalogue add-ons help coding agents work with Repomix.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 7 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00058 | $0.01293 |
| Opus 5.5 | $0.00023 | $0.00517 |
| Sonnet 5.5 | $0.00012 | $0.00259 |
| Haiku 4.5 | $0.00006 | $0.00129 |
Grade A, and why
repomix scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repomix — Codebase Packer & Analyzer
Pack entire codebases into a single, AI-friendly file for analysis. Repomix intelligently collects repository files, respects .gitignore, runs security checks, and generates structured output optimized for LLM consumption.
When to Use
- "Analyze this repo" / "Explore this codebase"
- "What's the structure of facebook/react?"
- "Find all authentication-related code"
- "How many tokens is this project?"
- "Pack this repo for AI analysis"
- "Show me the main components of vercel/next.js"
Quick Reference
Pack a Remote Repository
npx repomix@latest --remote <owner/repo> --output /tmp/<repo-name>-analysis.xml
Always output to a temporary directory (/tmp on Unix, %TEMP% on Windows) for remote repositories to avoid polluting the user's working directory.
Pack a Local Directory
npx repomix@latest [directory] --output /tmp/<name>-analysis.xml
Key Options
| Option | Description |
|---|---|
--style <format> |
Output format: xml (default, recommended), markdown, plain, json |
--compress |
Tree-sitter compression (~70% token reduction) — use for large repos |
--include <patterns> |
Include only matching patterns (e.g., "src/**/*.ts,**/*.md") |
--ignore <patterns> |
Additional ignore patterns |
--output <path> |
Custom output path (default: repomix-output.xml) |
--remote-branch <name> |
Specific branch, tag, or commit (for remote repos) |
Workflow
Step 1: Pack the Repository
Choose the appropriate command based on the target:
# Remote repository (always output to /tmp)
npx repomix@latest --remote yamadashy/repomix --output /tmp/repomix-analysis.xml
# Large remote repo with compression
npx repomix@latest --remote facebook/react --compress --output /tmp/react-analysis.xml
# Local directory
npx repomix@latest ./src --output /tmp/src-analysis.xml
# Specific file types only
npx repomix@latest --include "**/*.{ts,tsx,js,jsx}" --output /tmp/filtered-analysis.xml
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

repomix is a skill published in the GitHub repository yamadashy/repomix (28,851 stars, last pushed 4d ago), licensed MIT. It adds 58 tokens to every session and 1,293 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
