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 | $0.00025 | $0.00176 |
| Opus 5 | $0.00013 | $0.00088 |
| Sonnet 5 | $0.00005 | $0.00035 |
| Haiku 4.5 | $0.00003 | $0.00018 |
Grade A, and why
new-test 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 5d 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
Read ${CLAUDE_PLUGIN_ROOT}/skills/test-builder/SKILL.md and follow its
working algorithm from Step 0 (mode first) through Step 7 (review checklist),
consulting the reference files it names at each step.
The user's request: $ARGUMENTS
If the request does not state them, ask for: assessment mode (formative / diagnostic / summative), subject, grade/level, topics, and available administration time — then proceed. Deliver the specification, the matrix, the items each with a validated passport, the checklist report, and the mandatory human-review disclaimer.
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.
