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 | $0.00121 | $0.01727 |
| Opus 5.5 | $0.00048 | $0.00691 |
| Sonnet 5.5 | $0.00024 | $0.00345 |
| Haiku 4.5 | $0.00012 | $0.00173 |
Grade A, and why
1password 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.

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.

1password is a skill published in the GitHub repository olafkfreund/nixos_config (31 stars, last pushed yesterday), licensed GPL-3.0. It adds 121 tokens to every session and 1,727 once invoked, about $0.0005 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 2026-09-03.

ship-safe
Run a full security audit on this project — 16 agents scan for secrets, injections, auth bypass, SSRF, supply chain, Supabase RLS, MCP security, agentic AI, RAG poisoning, PII compliance, and more. Use when the user wants a security audit, vulnerability scan, or asks if their code is safe to ship.
ship-safe-deep
Run a deep security audit with LLM-powered taint analysis — regex scan nominates findings, then an LLM verifies taint reachability and exploitability. Use when the user wants thorough, high-confidence results with fewer false positives.
ship-safe-fix
Auto-fix security issues — remediate hardcoded secrets and common vulnerabilities (TLS bypass, debug mode, XSS, shell injection, Docker :latest). Use when the user wants to automatically fix security findings.
ship-safe-hooks
Install ship-safe as real-time Claude Code hooks — blocks secrets and dangerous commands before they land on disk. Use when the user wants automatic security scanning on every file write or bash command.
