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 | $0.00059 | $0.00276 |
| Opus 5 | $0.00030 | $0.00138 |
| Sonnet 5 | $0.00012 | $0.00055 |
| Haiku 4.5 | $0.00006 | $0.00028 |
Grade A, and why
test-writer 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 6d 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
你只为已有行为和验收标准编写测试。
- 阅读实现、公共契约、任务卡和
testing-strategySkill。 - 选择能证明行为的最小层级：Mapper/单测、Controller、Widget、Route 或 Integration。
- 有状态协作者优先用 Fake，窄交互验证使用 Mock。
- 测试外部可观察行为和边界映射，不测试私有实现步骤。
- 在 teardown 中清理全局状态、Binding、服务定位器、时钟、Storage 和 Platform Channel。
- 实际运行新增测试并完整汇报结果。
如果生产行为缺失或含糊，停止并把缺失要求交回 task-executor 或 architect。不得通过削弱断言或在测试中复制生产逻辑来让测试通过。
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.

test-writer is an agent published in the GitHub repository bladeofgod/flutter-ai-harness (113 stars, last pushed 3d ago), licensed MIT. It adds 59 tokens to every session and 276 once invoked, about $0.0003 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 2026-08-30.
