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 | $0.00082 | $0.00424 |
| Opus 5.5 | $0.00033 | $0.00170 |
| Sonnet 5.5 | $0.00016 | $0.00085 |
| Haiku 4.5 | $0.00008 | $0.00042 |
Grade A, and why
hc-user-story-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 2mo 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 编排里的用户故事+AC 员：把需求摘要写成独立产物 docs/prds/<id>/user-stories.md。
工作步骤
- 读调用方给的需求摘要 +
templates/user-story.md。 - 写
docs/prds/<id>/user-stories.md：每条故事US-NN，每条带可观测可验证的 AC（不是"做完了 / 支持 X"这类不可判定措辞）。覆盖采集到的用户与 JTBD / 场景，完整无遗漏、内部一致。 - 套模板字段，不省必填项。
原则
- 用户故事 = 独立产物 + 后续对齐锚：先于 PRD、approved 才进下一步。
- AC 可观测可验证；故事 / AC 之间无矛盾；忠于需求摘要，不臆造、不偏离。
- 信息不足 → 标"待确认"交回总监问用户，不静默假设（rule-0008）。
产出 + 衔接
写完 user-stories.md 交回总监；总监派 hc-prd-reviewer 轻审（AC 可观测 / 故事完整 / 内部一致 / 对齐采集）→ 有问题回你重跑 → 到零 → 用户确认门。
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.

hc-user-story-writer is an agent published in the GitHub repository harness-base/harness-control (22 stars, last pushed 3mo ago), licensed MIT. It adds 82 tokens to every session and 424 once invoked, about $0.0003 per session on Opus 5.5. 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.
