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.

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 | $0.00032 | $0.05270 |
| Opus 5 | $0.00016 | $0.02635 |
| Sonnet 5 | $0.00006 | $0.01054 |
| Haiku 4.5 | $0.00003 | $0.00527 |
Grade A, and why
comet-open 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.
How it starts
The opening of the file, as written. The whole thing — 290 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Comet 阶段 1:开启(Open)
开始或恢复前必须先读取并执行 comet-classic/reference/classic-layout.md;本文件中的 OpenSpec CLI 调用必须使用 adapter,文件路径必须使用该协议绑定的 <classic-*> 逻辑根。
前置条件
- 无活跃 change,或用户希望创建新 change
步骤
0. 输出语言约束
传递给 OpenSpec 的所有提问和产物要求都必须包含解析后的 Comet 产物语言,并使用 en、zh-CN 这类规范化 ID。.comet.yaml 尚不存在时依次读取项目 .comet/config.yaml 和全局 ~/.comet/config.yaml 的 classic.language;change 初始化后使用 comet state get <name> language 读取。没有配置语言时才回退到当前用户请求语言。生成的 proposal.md、design.md、tasks.md 必须以该语言为主语言。
0a. 当前 change 绑定
恢复已有 change 时先检查 <classic-change-dir>/.comet.yaml:
- 状态文件存在且可解析:先运行
comet classic workspace resolve <change-name> --json,进入返回的projectRoot后再选择 change - 状态文件缺失但 change 目录有效:先使用所选隔离方式准备工作区,再进入返回的
projectRoot运行comet state init <change-name> full --isolation <selected-isolation>,最后选择 change - 状态文件格式异常:停止并报告解析错误;从版本控制、备份或可验证产物人工修复后再继续,不得用
state set覆盖损坏文件
comet classic workspace resolve <change-name> --json
# 进入返回的 projectRoot
comet state select <change-name>
创建新 change 时,必须先完成 .comet.yaml 初始化,再立即运行同一命令;状态文件不存在前不得伪造选择。
0b. Open 前工作区决策与准备
创建 Classic change 时读取 comet-classic/reference/workspace.md。工作区决策必须在创建 OpenSpec artifacts 和 .comet.yaml 之前完成,不能推迟到 Build:
- 用户明确表达并行意图时直接使用
worktree,确保在创建 OpenSpec 和 state 前准备好独立工作区 - 未指定隔离方式时按参考文档处理:需要决策时展示合法的
current、branch、worktree选项,推荐只作说明 - 用户选择的
current或branch仍表示串行方式,不得把它描述为适合同时会话
新 change 在运行 OpenSpec new 前准备工作区:
comet classic workspace prepare <name> --isolation <current|branch|worktree> --json
# 进入返回的 projectRoot;后续 OpenSpec、state 和产物写入都必须在该目录执行
准备命令会复用已登记且分支匹配的 Worktree;分支仍存在但登记的 Worktree 已被移除时会重建。只有分支已重命名、被用户接管或无法确认归属时,才暂停请求显式 rebind。
0c. OpenSpec 兼容性检查
在任何 OpenSpec 状态或指令命令前运行:
comet classic openspec -- --version
本流程要求 OpenSpec >= 1.5.0。版本低于 1.5.0、无法解析版本、命令不可用或返回非零退出码时立即停止,并提示运行 npm install -g @fission-ai/openspec@latest 后重试;不得继续使用缺少 applyRequires、artifactPaths、changeRoot 或 resolvedOutputPath 契约的旧 CLI。
1. 探索想法与需求澄清
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 4d ago First seen · 290 lines · 32 tokens per session scan A 7dbbbe5446cf
comet-open is a skill published in the GitHub repository rpamis/comet (2,902 stars, last pushed 2d ago), licensed MIT. It adds 32 tokens to every session and 5,270 once invoked, about $0.0002 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.
