Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

omk-agent 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 11d 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

Trigger Examples

  • "@agent 所有 JSON 操作必须用 jq"
  • "add this as a permanent rule"
  • "enforce: never skip tests"
  • "把这个原则写进规则"
  • "@agent submodule 修改必须走 worktree"

Agent — Distill Top-Level Principle

Capture a principle into knowledge/rules.md as a staged rule.

Input

$ARGUMENTS

Process

  1. If no input provided, ask user: "What principle should I capture?"
  2. Extract: trigger scenario + DO/DON'T action + keywords
  3. Check dedup: grep -iw keywords in knowledge/rules.md and knowledge/episodes.md
    • Already in rules → tell user, skip
    • Already in episodes with same meaning → tell user, suggest upgrading to rule
  4. Determine severity: 🔴 (critical, always inject) or 🟡 (relevant, keyword-matched)
  5. Find or create matching section header ## [keyword1,keyword2] in knowledge/rules.md
  6. Append rule under that section, format: 🔴 N. SUMMARY or 🟡 N. SUMMARY
  7. Cap: max 5 rules per section, max 30 rules total. Warn if approaching limit.
  8. Output: 📝 Captured → rules.md: 'SUMMARY'

Rules

  • Summary must contain actionable DO/DON'T, not narrative
  • Keywords: 1-3 english technical terms, ≥4 chars each, comma-separated
  • Default severity: 🟡 (only use 🔴 for principles that should apply to EVERY conversation)

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.
