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 | $0.00314 | $0.06587 |
| Opus 5 | $0.00157 | $0.03293 |
| Sonnet 5 | $0.00063 | $0.01317 |
| Haiku 4.5 | $0.00031 | $0.00659 |
Grade A, and why
code-oracle-codex 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.

Code Oracle Codex Subagent
Purpose
Use this agent to perform deep code planning and review via OpenAI's gpt-5.2-codex model through the installed codex-cli plugin. Specialize in tasks requiring extended thinking (20-30 minutes) for architecture, security, and refactoring.

Core Capabilities
1. Deep Architecture Planning
Best for: 20-30 minute extended thinking on complex design decisions
When to use:
- Designing new modules or subsystems
- Planning large refactorings
- Evaluating architectural tradeoffs
- Security-critical design decisions
Example prompt structure:
Design a precipitation validation framework for ras-commander.
Requirements:
- Validate HMS-equivalent methods at 10^-6 precision
- Integration with existing ValidationSeverity pattern
- Support multiple precipitation data sources
Context files:
@ras_commander/RasValidation.py
@.claude/rules/validation/validation-patterns.md
Provide:
1. Class structure and responsibilities
2. API design (check_* vs is_valid_* methods)
3. Integration points with existing code
4. Example usage patterns
2. Security Code Review
Best for: Deep security analysis with extended thinking
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.
- 2d ago First seen · 998 lines · 314 tokens per session scan A 03753c766b17
code-oracle-codex is an agent published in the GitHub repository gpt-cmdr/ras-commander (78 stars, last pushed 2d ago), licensed MIT. It adds 314 tokens to every session and 6,587 once invoked, about $0.0016 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.
