Repomix

Repomix is a skill for Claude Code, Codex from sergei-aronsen/claude-code-toolkit. It costs 73 tokens per session (1,844 once invoked), scanned A, original, MIT.

A repository-packing tool that combines a whole local or remote codebase into one XML, Markdown, or JSON file for AI review.

In plain words
What is it for?
Use it for architecture reviews, full-codebase audits, cross-repository handoffs, comparing remote branches, or giving an AI context about an entire repository.
Why use it?
It avoids sending many separate files when an AI needs a broad view of the project. Optional compression keeps module signatures while leaving out function bodies.

Token cost

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.

Security

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 4d 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.

Repomix Skill

Load this skill when packing repositories for AI consumption — local or remote. Repomix bundles a codebase into a single XML/Markdown/JSON file, with optional tree-sitter compression that keeps signatures and drops bodies.


Rule

REPOMIX IS FOR BREADTH, NOT DEPTH.

It gives an LLM a wide signatures-level view of the whole codebase. It is not a substitute for reading one file carefully or grepping for one function. Use the right tool for the job.


When To Use Repomix

Task Tool Why
Find one function definition find-function or Grep Repomix overshoots — 1000 files for 1 symbol
Read a specific file Read Direct, exact, no subprocess
Open exploration over 2-3 files Explore agent Built-in budget control
Architectural review across the whole repo Repomix --compress Signatures of every module, fits LLM context
Hand the codebase to ChatGPT / web Claude / Gemini Repomix → clipboard One file, formatted for LLMs
Compare two upstream revisions Repomix --remote --remote-branch No clone needed
Council needs full-codebase context brain --pack (automatic in v6.23+) Already wired in
Attach codebase to a GitHub issue / PR Repomix --style markdown Renders nicely on GitHub

If the task isn't on the "use" rows above — pick a sharper tool.


How To Invoke

From inside Claude Code

/pack                                    # current repo, defaults
/pack --remote yamadashy/repomix         # remote
/pack --include "src/**" --format md     # subset + markdown
/pack --to clipboard                     # copy, don't write a file

The /pack command is the supported entry point. It writes to .claude/scratchpad/pack-<timestamp>.<ext>.

From your shell

# Pack this repo

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.
