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 | $0.00049 | $0.01352 |
| Opus 5 | $0.00024 | $0.00676 |
| Sonnet 5 | $0.00010 | $0.00270 |
| Haiku 4.5 | $0.00005 | $0.00135 |
Grade A, and why
claude-code 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Code Delegation
Delegate coding work to Claude Code, Anthropic's autonomous coding agent CLI.
Setup (once): npm install -g @anthropic-ai/claude-code && claude auth login · verify with claude auth status / claude doctor. CI token: claude setup-token. Full auth/install variants → references/flags.md.
Platform check (before running anything): detect the OS first. All shell examples in this skill are POSIX (bash). Linux/macOS run them as-is. On Windows, run Claude Code natively in PowerShell/Git Bash for print and background modes, but interactive tmux orchestration requires WSL. Shell-syntax translation table (quoting, env vars, piping, paths) → references/platforms.md.
Mode Selection (decide FIRST)
| Task shape | Mode | Why |
|---|---|---|
| One-shot task: fix bug, add feature, review diff, extract data | Print -p ← default |
No PTY, no dialogs, structured output |
| Multi-turn iterate: refactor → review → fix → test; needs slash commands | Interactive tmux → references/interactive-tmux.md |
Full REPL, requires dialog handling |
| Long-running, shouldn't block; large fan-out supervision | Background --bg |
Native supervision via claude agents |
| High-stakes PR review | claude ultrareview [pr#] |
Cloud multi-agent, exit-code driven (uploads diff to cloud — never on branches with secrets) |
Do NOT hand-roll tmux fan-outs for parallel work — prefer --bg + claude agents --json --all.
Print Mode (the 90% path)
terminal(command="claude -p 'Fix the auth bug in src/auth.py' \
--allowedTools 'Read,Edit' --max-turns 10 --output-format json",
workdir="/path/to/project", timeout=180)
Always set: workdir · --max-turns (5–10; print-mode only) · --allowedTools (least privilege: Read,Edit,Write,Bash, patterns like Bash(git *)).
JSON result fields: result (text) · session_id (for resume) · subtype (success | error_max_turns | error_budget) · total_cost_usd · num_turns · structured_output (with --json-schema).
What ships with it
5 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.

claude-code is a skill published in the GitHub repository XiaomiMiMo/MiMo-Code (12,904 stars, last pushed 2d ago), licensed MIT. It adds 49 tokens to every session and 1,352 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.
