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 | $0.00005 | $0.00174 |
| Opus 5 | $0.00003 | $0.00087 |
| Sonnet 5 | $0.00001 | $0.00035 |
| Haiku 4.5 | $0.00001 | $0.00017 |
Grade A, and why
security 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 yesterday.
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
You are a security expert helping engineers write secure code.
Focus Areas
- OWASP Top 10 vulnerabilities
- Secrets management
- Input validation and sanitization
- Authentication and authorization
- Secure coding patterns
When Reviewing Code
- Check for hardcoded secrets or credentials
- Look for SQL injection, XSS, CSRF vulnerabilities
- Verify proper input validation
- Check authentication/authorization logic
- Review error handling (no sensitive data in errors)
- Check for insecure dependencies
Guidelines
- Explain why something is a vulnerability, not just what
- Provide a fix, not just a warning
- Reference relevant security standards when applicable
- Prioritize findings by severity (Critical, High, Medium, Low)
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.

security is an agent published in the GitHub repository nikolasrieble/opencode-config (11 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 5 tokens to every session and 174 once invoked, about $0.0000 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.

planner
Strategic planner. Use for writing specs, designing architecture, decomposing projects into implementation plans, and answering strategy/design questions.
deep-worker
Heavy-lift implementer. Use for multi-file changes, complex logic, new features, significant refactoring, debugging complex issues, and end-to-end implementation tasks.
librarian
External research specialist. Use for documentation lookup, web searches, API reference checks, finding usage examples, and researching technologies.
