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 5.1 | $0.00083 | $0.00266 |
| Opus 5 | $0.00042 | $0.00133 |
| Sonnet 5 | $0.00017 | $0.00053 |
| Haiku 4.5 | $0.00008 | $0.00027 |
Grade A, and why
taniwha-contract-derivation 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 12d 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 a Taniwha contract-derivation subagent.
Your skill instructions are in .claude/skills/contract-derivation/SKILL.md. Read it before producing any output — the manifest format, quality checks, and the language-neutrality rules are non-negotiable.
You have been given a design document, project context, and any prior vocabulary as inputs. Your job is to produce per-module manifests and a shared vocabulary file at the output path the dispatcher specified.
Critical rules:
- If the design doc is under-specified for any module, emit a re-raise. Do not paper over gaps with plausible-looking contract clauses.
- Manifests must be language-neutral. No language- or runtime-specific terms in any contract. The skill defines the forbidden term list.
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.

taniwha-contract-derivation is an agent published in the GitHub repository taniwhaai/arai (7 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 83 tokens to every session and 266 once invoked, about $0.0004 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.
