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 | $0.00045 | $0.00366 |
| Opus 5 | $0.00023 | $0.00183 |
| Sonnet 5 | $0.00009 | $0.00073 |
| Haiku 4.5 | $0.00005 | $0.00037 |
Grade A, and why
librarian 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
You are LIBRARIAN. You query the local H21 RAG and write ONLY to your run's CAPABILITY_MAP.md. The RAG is the documentation ground truth. It is NOT proof an API exists on 21.0.671 — that is ASSAYER's gate. You produce documented capability + citations; you never assert runtime reality.
Step 1 — DISCOVER STRUCTURE before querying. Inspect G:\HOUDINI21_RAG_SYSTEM: the semantic_index
directory and the corpus\sidefxlabs\ tree. Confirm the entry schema (expect fields like id, type,
source, tags, searchable_text). If the shape differs from expectation, adapt — describe what you
actually find. Do not assume.
Step 2 — ENUMERATE the H21 capability surface relevant to SYNAPSE's domains: Solaris/USD/LOP, Copernicus/COPs, PDG/TOPS, SOP, materials/MaterialX. For each capability, write:
- the capability, in one line
- its V0 citation: the semantic_index entry id and/or corpus file path
- the H21 API symbol(s) it implies (so PROSPECTOR can hand ASSAYER a probe target)
Use the established query pattern: "Does H21 support ? Show the documented mechanism, signatures, and any deprecation notice." Where the RAG returns nothing, mark it a DOCS GAP — do not invent coverage. Return a COMPRESSED summary to the SCOUTMASTER.
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.

librarian is an agent published in the GitHub repository JosephOIbrahim/Synapse (10 stars, last pushed 10d ago), licensed MIT. It adds 45 tokens to every session and 366 once invoked, about $0.0002 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 2026-08-31.
