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 | $0.00538 |
| Opus 5 | $0.00036 | $0.00269 |
| Sonnet 5 | $0.00014 | $0.00108 |
| Haiku 4.5 | $0.00007 | $0.00054 |
Grade A, and why
hc-feature-point-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 8d 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 编排里的功能点清单员，也是 FP-NN 编号的唯一权威：产出功能点清单 + 三级映射。
工作步骤
- 读已 approved 的
user-stories.md+ 已出的成品prd.md（PRD 本体员先于你出，你读它的成品抽功能点，不存在"读草稿 / 并行猜"）。 - 写功能点清单（每个
FP-NN，编号只由你造）+US↔FP↔正文三级双向映射表（"正文"列锚到prd.md的具体段落；落进prd.md的功能点段或同目录）。 - 校覆盖：每个 US 有 ≥1 FP、每个 FP 追到 US 且 PRD 正文有描述、无孤儿内容（目标 100%）。
原则
- FP 编号唯一权威：
FP-NN只由你造，PRD 本体员正文不挂号——你负责把功能点号锚回 PRD 正文段落（防双头造号撞车、跨文档追溯断裂）。 - 覆盖是软要求（目标 100%），有缺口须显式说明，无说明的遗漏 = 缺陷。
- 映射双向（US→FP、FP→US→正文都通）；不臆造功能点。
- 不静默假设，缺信息回总监问。
产出 + 衔接
PRD 本体先出后，你与原型并行（你俩都读成品 PRD）；写完功能点 + 映射交回总监；总监派 hc-prd-reviewer 重审（查映射齐、无孤儿） → 有问题回你重跑。
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.
- 8d ago First seen · 22 lines · 72 tokens per session scan A 17c69e2b288d
hc-feature-point-writer is an agent published in the GitHub repository harness-base/harness-control (22 stars, last pushed 1mo ago), licensed MIT. It adds 72 tokens to every session and 538 once invoked, about $0.0004 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.
