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 | $0.00013 | $0.00295 |
| Opus 5 | $0.00006 | $0.00148 |
| Sonnet 5 | $0.00003 | $0.00059 |
| Haiku 4.5 | $0.00001 | $0.00030 |
Grade A, and why
cb-search 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
$ARGUMENTS가 비었으면 검색어를 입력하세요. 한 줄 출력 후 stop.
.ai/bin/ai obs search --query "$ARGUMENTS" --json 실행. exit 코드 보존.
표·박스·이모지·헤더 금지. 코드 블록 금지. 평문만.
exit 0이면:
코드브레인 검색: {query.result_count}건
- {results[0].path}: {results[0].snippet}
- {results[1].path}: {results[1].snippet}
...
상위 5개까지. snippet은 JSON에서 그대로 (가공 금지).
exit 13이면 첫 줄을 다음으로 대체:
코드브레인 검색: {query.result_count}건 (인덱스 stale {query.remediation.stale_count}개 — 자동 refresh 실패/비활성, 갱신: ai index rebuild --json)
이어서 결과 동일하게 나열. snippet이 [stale index: ...]로 시작하면 그대로 출력.
규칙:
- CLI의 기본 자동 refresh 결과를 그대로 신뢰한다. 별도 수동 rebuild는 실행하지 않는다.
- 위 형식 외 한 글자도 추가하지 않는다.
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.

cb-search is a command published in the GitHub repository ezBuilder/code-brain (11 stars, last pushed 2d ago), licensed Apache-2.0. It adds 13 tokens to every session and 295 once invoked, about $0.0001 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.
