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 | $0.00950 | $0.00950 |
| Opus 5 | $0.00475 | $0.00475 |
| Sonnet 5 | $0.00190 | $0.00190 |
| Haiku 4.5 | $0.00095 | $0.00095 |
Grade A, and why
shannot CLAUDE.md 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 today.
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 — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Overview
Shannot is a sandboxed system administration tool for LLM agents using PyPy sandbox architecture with syscall-level virtualization.
Key Facts:
- Python 3.11+ host code, Python 3.6 sandboxed code
- Zero runtime dependencies (stdlib only)
- Test directory is
test/(nottests/)
CLI Commands
# Core workflow
shannot run SCRIPT # Execute Python script in sandbox
shannot approve [SESSION] # Interactive approval TUI
shannot status # Check runtime and pending sessions
# Setup (interactive menu or subcommands)
shannot setup # Interactive setup menu
shannot setup runtime # Install PyPy 3.6 stdlib
shannot setup remote add NAME # Add SSH remote target
shannot setup remote list # List configured remotes
shannot setup remote test NAME # Test SSH connection
shannot setup mcp install # Install MCP integration
Key Options: --target NAME, --dry-run, --color/--no-color
Development Commands

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.

shannot CLAUDE.md is an instructions file published in the GitHub repository corv89/shannot (25 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 950 tokens to every session, about $0.0047 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 2026-09-01.
