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 5.1 | $0.00019 | $0.00115 |
| Opus 5 | $0.00010 | $0.00057 |
| Sonnet 5 | $0.00004 | $0.00023 |
| Haiku 4.5 | $0.00002 | $0.00012 |
Grade A, and why
change-safety 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 9d 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
Change Safety
- Locate the owning module and its nearest tests before editing.
- Describe the intended behavioral change and a verification condition.
- Keep unrelated refactors out of the task unless they block correctness.
- Treat a passing command as evidence only for what that command actually covers.
Record the relevant evidence, decision, and verification result in the working set or handoff. This skill does not grant tools or bypass host permissions.
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.

change-safety is a skill published in the GitHub repository storious/agent-playbook (2 stars, last pushed 9d ago), licensed MIT. It adds 19 tokens to every session and 115 once invoked, about $0.0001 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 2026-08-31.
