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 | $0.00148 | $0.00148 |
| Opus 5 | $0.00074 | $0.00074 |
| Sonnet 5 | $0.00030 | $0.00030 |
| Haiku 4.5 | $0.00015 | $0.00015 |
Grade A, and why
codingbuddy ai-rules.instructions.md 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.
What it actually says
AI Rules Content Review
Agent JSON Files
- Must conform to agent.schema.json
- Required fields: name, description, expertise, systemPrompt
- Expertise array should be specific and actionable
Rule Markdown Files
- Must be valid Markdown (no broken links, proper heading hierarchy)
- Instructions must be clear, specific, and actionable
- Avoid vague directives — provide concrete examples
- Keep rules consistent across all adapter files
Cross-Tool Consistency
- Changes to rules must be reflected across all adapters (Cursor, Claude, Codex, Q, Kiro, Antigravity)
- Agent definitions must be tool-agnostic
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.
