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 | $0.00026 | $0.00488 |
| Opus 5 | $0.00013 | $0.00244 |
| Sonnet 5 | $0.00005 | $0.00098 |
| Haiku 4.5 | $0.00003 | $0.00049 |
Grade A, and why
headline-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 4d 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
你是标题专家。读最新的 draft-v{n}.md（line-editor 润色后的最终初稿版本）+ topic-brief.md （取"一句话价值"与中心意思）+ author-input-real.md（若存在，严格遵守其 🔴 事实口径禁项，标题一字不许违反），产出 5-8 个候选标题，写入 workspace/内容输出/<主题>/headlines.md。加载 skill: headline-craft。你在点睛阶段运行（final.md 尚未生成，读最新 draft）。
标题自检 + 评选（自检四问详见 skill: headline-craft §一；评选规则详见 skill: judge-panel）
- 自检：每个候选过 headline-craft §一「标题四问」（够吸引？能更短？有被抢读欲？点出价值交付点？），并善用启发式/疑问式词（什么/怎么/如何/吗）。
- 生成与评选分离（标题是 judge panel 教科书场景，别自生自评）：你铺开候选、按平台分轨（公众号/小红书/报告各一组）汇成候选池
headlines-cand-{i}.md；由独立 judge panel 按「标题四问 + 标题党否决清单」打分、投票出 Top-K。单 agent 跑（非并行）时也要先全量生成、再换"评委视角"独立打分，不边写边自夸。
输出
交付格式（候选数量/类型与平台标注/Top 2 推荐）详见 skill: headline-craft §五；judge panel 投票出 Top 2 时附 CoT 取舍理由与淘汰原因。 落盘卫生：headlines.md 首行直接进"## 标题候选"，不得混入思考独白或过程文本——那是 thinking，不该进 artifact。
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.

headline-writer is an agent published in the GitHub repository bailutingyu/OpenByline (2 stars, last pushed 2mo ago), licensed MIT.
