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.

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 | $0.00043 | $0.01528 |
| Opus 5 | $0.00022 | $0.00764 |
| Sonnet 5 | $0.00009 | $0.00306 |
| Haiku 4.5 | $0.00004 | $0.00153 |
Grade A, and why
ck: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 2d 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 — 249 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repomix Skill
Repomix packs entire repositories into single, AI-friendly files. Perfect for feeding codebases to LLMs like Codex, ChatGPT, and Gemini.
When to Use
Use when:
- Packaging codebases for AI analysis
- Creating repository snapshots for LLM context
- Analyzing third-party libraries
- Preparing for security audits
- Generating documentation context
- Investigating bugs across large codebases
- Creating AI-friendly code representations
Quick Start
Check Installation
repomix --version
Install
# npm
npm install -g repomix
# Homebrew (macOS/Linux)
brew install repomix
Basic Usage
# Package current directory (generates repomix-output.xml)
repomix
# Specify output format
repomix --style markdown
repomix --style json
# Package remote repository
npx repomix --remote owner/repo
# Custom output with filters
repomix --include "src/**/*.ts" --remove-comments -o output.md
Core Capabilities
Repository Packaging
- AI-optimized formatting with clear separators
- Multiple output formats: XML, Markdown, JSON, Plain text
- Git-aware processing (respects .gitignore)
- Token counting for LLM context management
- Security checks for sensitive information
Remote Repository Support
Process remote repositories without cloning:
# Shorthand
npx repomix --remote yamadashy/repomix
# Full URL
npx repomix --remote https://github.com/owner/repo
# Specific commit
npx repomix --remote https://github.com/owner/repo/commit/hash
Comment Removal
Strip comments from supported languages (HTML, CSS, JavaScript, TypeScript, Vue, Svelte, Python, PHP, Ruby, C, C#, Java, Go, Rust, Swift, Kotlin, Dart, Shell, YAML):
repomix --remove-comments
Common Use Cases
Code Review Preparation
# Package feature branch for AI review
repomix --include "src/**/*.ts" --remove-comments -o review.md --style markdown
Security Audit
# Package third-party library
npx repomix --remote vendor/library --style xml -o audit.xml
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 2d ago First seen · 249 lines · 43 tokens per session scan A f00ad398bfc1
ck:repomix is a skill published in the GitHub repository manhvann/codexkit (88 stars, last pushed 4d ago), licensed MIT. It adds 43 tokens to every session and 1,528 once invoked, about $0.0002 per session on Opus 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.
