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 | $0.00278 | $0.00278 |
| Opus 5 | $0.00139 | $0.00139 |
| Sonnet 5 | $0.00056 | $0.00056 |
| Haiku 4.5 | $0.00028 | $0.00028 |
Grade A, and why
code-airlock AGENTS.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 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.
What it actually says
Agent Instructions
This repo is code-airlock: a small Bash wrapper around Docker Sandboxes for running coding agents in disposable microVMs.
Working Rules
- Keep the tool dependency-light. Do not add package managers, build systems, or new runtime dependencies unless explicitly requested.
- Prefer small, reviewable Bash changes in
code-airlock. - Keep docs in
README.mdaligned with script behavior. - Do not change security defaults casually. Explain any change to network policy, credential handling, clone mode, or sandbox deletion behavior.
- Do not push to GitHub or publish releases unless explicitly asked.
Verification
After editing the wrapper, run:
bash -n code-airlock
shellcheck code-airlock
./code-airlock help
For docs-only changes, at least check for stale command names:
rg -n "claude-sbx|code-airlock|sbx " README.md code-airlock sandbox.conf.example AGENTS.md
Sandbox Workflow
The agent works in Docker Sandboxes clone mode. Commit any finished edits inside the sandbox so the host can retrieve them with:
code-airlock fetch
code-airlock diff
code-airlock merge
If work is not committed in the sandbox, it will not come back through the normal fetch/diff/merge workflow.
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.

code-airlock AGENTS.md is an instructions file published in the GitHub repository Trivo25/code-airlock (20 stars, last pushed 1mo ago), licensed MIT. It adds 278 tokens to every session, about $0.0014 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.
