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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00016 | $0.00194 |
| Opus 5.5 | $0.00006 | $0.00078 |
| Sonnet 5.5 | $0.00003 | $0.00039 |
| Haiku 4.5 | $0.00002 | $0.00019 |
Grade A, and why
registry-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 8d 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
Registry Search
Search the registry before authoring a new reusable package. Read a
candidate's source (pcb list -m -json <module-url>@<version> reports its
dir) for its public API; do not infer IO or config names from a search result.
Prefer a reusable module that matches the need, then a component with its
support circuitry, then a primitive. Instantiate the chosen .zen entrypoint
with Module() and follow zener-language for dependencies; do not hand-edit
pcb.toml.
Discover or clone other boards only when the user explicitly asks, and clone them outside the current checkout.
If no suitable package exists or one needs a fix, use librarian in a registry
checkout; from board work, prepare a librarian-dispatch request.
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.

registry-search is a skill published in the GitHub repository diodeinc/pcb (466 stars, last pushed today), licensed MIT. It adds 16 tokens to every session and 194 once invoked, about $0.0001 per session on Opus 5.5. 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.
