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 | $0.00049 | $0.00643 |
| Opus 5.5 | $0.00020 | $0.00257 |
| Sonnet 5.5 | $0.00010 | $0.00129 |
| Haiku 4.5 | $0.00005 | $0.00064 |
Grade A, and why
safe-ops 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 1mo 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Safe Ops
Make the safe path easy. Check authority, preview material effects, execute the named operation, and read back the result. No ritual approval loops.
One authorization policy
- A clear request naming an operation and a resolvable target authorizes that scope. "Commit and push this branch" and "open the PR" do not need another generic "proceed?". Show a compact preview and continue.
- A review, diagnosis or QA request does not authorize publishing or fixing. "Ship it" does not silently authorize merge, tag, deploy or database changes.
- Ask when the action/target is ambiguous, blast radius exceeds the request, or new evidence materially changes the risk. Do not turn an inferred goal into authority for a remote mutation.
- Destructive/history-rewriting actions require approval of the exact preview: targets, old/new state, losses, recovery and its limits. An earlier explicit approval of that unchanged preview remains valid.
- Higher-priority and environment-specific gates still apply, including production restrictions and the user's exact-diff approval for global Codex instructions/configuration/skills. Unknown environment = production. Never infer ST/PROD write authorization from local-development permission.
Risk, proportional ceremony
| Level | Typical action | Handling |
|---|---|---|
| L1 | Status, diff, bounded read-only query | Proceed within read-access rules |
| L2 | Authorized local commit, topic-branch fast-forward push | Short preview, execute, read back |
| L3 | Shared branch push/merge, PR publication, infrastructure/API writes | Verify named target, effects and existing authorization; ask only if missing |
| L4 | Force push, hard reset, destructive deletion, schema/data loss | Exact reviewed preview, explicit approval and recovery plan |
A topic push can trigger CI or preview deployment; discover meaningful side effects before treating it as L2. "Reversible" does not mean cost-free.
References
The policy above is canonical. Read only the relevant domain; "confirm" in a recipe means establish authorization under this policy, not automatically ask again. Examples are not authority.
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.

safe-ops is a skill published in the GitHub repository CassioRoos/godfly-skills (1 stars, last pushed yesterday), licensed MIT. It adds 49 tokens to every session and 643 once invoked, about $0.0002 per session on Opus 5.5. 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.
