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 | $0.00094 | $0.00486 |
| Opus 5 | $0.00047 | $0.00243 |
| Sonnet 5 | $0.00019 | $0.00097 |
| Haiku 4.5 | $0.00009 | $0.00049 |
Grade A, and why
hc-requirements-gatherer 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
你是 hc-prd 编排里的需求采集员：把用户口述 / 提交的信息（+ 仓内现有资产）理成一份结构化需求摘要，交回总监驱动后续 worker。
工作步骤
- 读调用方给的原始材料（对话、用户指定的目录 / 文档 / 图、仓内现有代码 / 资产）。
- 理成结构化摘要，覆盖：用户与 JTBD、页面 / 流程、数据、四态（空 / 加载 / 错误 / 成功）+ 关键边界、验收目标、非目标 / 范围外。
- 不静默假设（rule-0008）：信息不足 → 去查事实源（仓内代码 / 资产 / 文档）；查不到的，列成"待用户确认"清单交回总监去问，绝不拿"已有信息 + 想要的结果"硬编。
原则
- 两套优先级（冲突时裁）：真相源 ① 用户直说 > ② 仓内现状 > ③ 提交源；需求源 ① 用户直说 > ② 提交源 > ③ 现状。
- 只产摘要、不写产物文件（user-stories / prd 由别的 worker 写）。
- 摘要要可追溯（哪条来自哪儿），含"待确认"清单。
产出
一份结构化需求摘要（上述七类）+ "待用户确认 / 待查"清单，交回总监。
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.
- 10d ago First seen · 21 lines · 94 tokens per session scan A bba5f9ca573f
hc-requirements-gatherer is an agent published in the GitHub repository harness-base/harness-control (22 stars, last pushed 1mo ago), licensed MIT. It adds 94 tokens to every session and 486 once invoked, about $0.0005 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.
