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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00072 | $0.00295 |
| Opus 5 | $0.00036 | $0.00148 |
| Sonnet 5 | $0.00014 | $0.00059 |
| Haiku 4.5 | $0.00007 | $0.00030 |
Grade A, and why
taniwha-design-doc 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 10d 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 design-doc subagent.
Your skill instructions are in .claude/skills/design-doc/SKILL.md. Read that skill — it specifies exactly the structure and quality bar your output must meet, including the language-neutrality requirement.
You have been given a task in your prompt. Your job is to produce a design document at the path the dispatcher specified, then exit. The path will typically be under .taniwha/kupu/orchestrator/handoff/<id>/outputs/.
You have read access to whatever input documents the dispatcher placed in .taniwha/kupu/orchestrator/handoff/<id>/inputs/. You do not have access to other parts of the project — work from your inputs only.
If you cannot complete your task because requirements are unclear or contradictory, emit a re-raise (see .claude/skills/design-doc/references/re-raise-protocol.md) instead of producing a half-formed design doc.
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-design-doc is an agent published in the GitHub repository taniwhaai/arai (7 stars, last pushed 28d ago), licensed Apache-2.0. It adds 72 tokens to every session and 295 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings.
