A documentation lookup workflow for external libraries, software development kits, frameworks, application programming interfaces, and packages.

Use it to find the right library documentation and verify APIs, configuration keys, command-line options, versions, and code examples.

It checks version-specific reference material before suggesting code, reducing the risk of using made-up or outdated names, settings, flags, or examples.

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.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00054	$0.00274
Opus 5.5	$0.00022	$0.00110
Sonnet 5.5	$0.00011	$0.00055
Haiku 4.5	$0.00005	$0.00027

Security

Grade A, and why

oz 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 2mo 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

Oz Documentation Workflow

Use Oz first for external libraries, SDKs, APIs, frameworks, and packages.

Workflow:

Call resolve-library-id to find the exact Oz library ID.
Call get-library-docs with the resolved library ID and the user's topic.
If the user asks for a version, pass the version explicitly.
Use the returned documentation as the source of truth.
If Oz has no matching library, lacks the requested version, or returns insufficient context, then fall back to Context7, official docs, source repositories, or web search.

Reliability rules:

Do not hallucinate APIs, config keys, versions, CLI flags, or behavior.
If docs are missing or unclear, say that and fetch another authoritative source.
Stop calling Oz once enough context has been retrieved.
Do not repeatedly call tools with near-duplicate topics unless the first result was insufficient.
Prefer exact identifiers from Oz snippets: function names, env vars, routes, package names, error codes, config keys.

Changes

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.
