comet-tweakA skill your agent uses when 用户要进行可收敛为单一 OpenSpec change 的轻量或中等变更,且不需要完整设计;也用于恢复 tweak workflow。
Comet Tweak is an agent skill from rpamis/comet. Use when 用户要进行可收敛为单一 OpenSpec change 的轻量或中等变更,且不需要完整设计;也用于恢复 tweak workflow。
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. The repository describes itself as: Comet: agent skill harness for turning ideas into evaluated workflows. The licence is MIT.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit c28e724. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
nodemvnnpmFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Comet Tweak loads about 1.6k tokens when it runs. Until then it costs about 22 tokens; SKILL.md has 558 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/comet-tweak/SKILL.md (or your agent's skills folder).Tweak 是 Comet 五阶段能力的预设工作流,不是独立的平行流程。它串联 OpenSpec 的核心流程,复用 open、build、verify、archive 能力,仅跳过 Superpowers brainstorming 和完整 plan。
适用于串联 OpenSpec 的轻量改动,例如配置调整、文档或 prompt 优化,以及需 spec 驱动(含 delta spec)但不需要完整 /comet 深度设计流程的中等变更。delta spec 在 tweak 中是一等公民正常产物,需要 delta spec 本身不构成升级理由。
适用条件(必须全部满足):
不适用:如变更过程中命中质变信号(见「升级判定」章节),由用户决定是否升级为完整 /comet 流程。
精简版 OpenSpec 产物必须使用触发本次工作流的用户请求语言。
执行链路:open → OpenSpec apply → verify → archive。Tweak 为每个阶段提供默认决策:精简开启、通过 OpenSpec apply 直接构建、按规模与 delta spec 判定验证轻重、验证通过后进入归档前最终确认。
开始前按 comet/reference/scripts.md 定位 Comet 脚本(定位 comet-env.mjs);从任意入口恢复时先按 comet/reference/context-recovery.md 确认 phase/workflow。
复用 Comet open 能力创建 change,但使用 tweak 默认值:不执行 openspec-explore 长探索,直接进入精简 change 创建。
立即执行: 使用 Skill 工具加载 openspec-new-change 技能。禁止跳过此步骤。
技能加载后,按其指引创建精简版产物:
proposal.md — 变更动机 + 目标 + 范围design.md — 简短实现说明(无需方案对比)tasks.md — 任务清单(建议控制在合理规模,数量本身不触发升级,见「升级判定」)delta spec(可选)— 若变更影响已有 spec 的验收场景,作为正常产物创建(仅含 ## MODIFIED Requirements 或 ## ADDED Requirements)。delta spec 是 OpenSpec brownfield 改动的核心产物,需要 delta spec 本身不构成升级理由初始化 Comet 状态文件:
node "$COMET_STATE" init <name> tweak初始化后验证状态:
node "$COMET_STATE" check <name> open阶段守卫完成 open → build 过渡:
node "$COMET_GUARD" <change-name> open --apply使用 tweak 默认值:build_mode: direct。跳过 Superpowers brainstorming 和 writing-plans,改由 OpenSpec 的 apply action 执行当前 change 的 tasks。
<IMPORTANT>
这条 apply 路径只属于 tweak。完整 `/comet` 或 `workflow: full` 不得套用 tweak 的 `openspec-apply-change` 构建路径;full 仍必须先通过 `/comet-design` 生成 Design Doc,再由 `/comet-build` 通过 Superpowers `writing-plans`、执行方式选择和对应执行技能完成构建。
</IMPORTANT>
继续或开始修改前,按 comet/reference/dirty-worktree.md 协议处理未提交改动。若归因后发现命中质变信号或文件数 tripwire,按本文件「升级判定」处理。
立即执行: 使用 Skill 工具加载 openspec-apply-change 技能。禁止跳过此步骤。
技能加载后,以当前 <change-name> 作为输入,按 openspec-apply-change 的指引执行 OpenSpec apply 流程:
openspec status --change "<name>" --json,确认 schema 和任务 artifactopenspec instructions apply --change "<name>" --json,读取 OpenSpec 返回的 apply 指令、contextFiles、任务进度和动态 instructionmvn spotless:apply、npm run format 等)openspec-apply-change 规则将对应 task 勾选为完成tweak: <简述变更>执行 tweak 期间,只要运行程序、测试、构建或手动验证时出现崩溃、异常行为、测试失败或构建失败,必须使用 Skill 工具加载 Superpowers systematic-debugging 技能。在完成根因调查前,不得提出或实施源码修复。
具体调查、最小失败测试、修复验证和保持当前 change 验证闭环的要求,按 comet/reference/debug-gate.md 执行。
升级判定检查:build 全程持续判断,并在 build→verify 守卫执行前做一次集中复核。判定采用三层分工(详见「升级判定」章节):质变信号靠 agent 语义识别、文件数仅作提示交用户拍板、scale 脚本仅管验证轻重。命中质变信号或文件数超提示阈值时,不得自行升级或自行判定可继续,必须按 comet/reference/decision-point.md 暂停并把决策权交给用户:继续 tweak 轻量流程,还是升级为完整 /comet。
运行阶段守卫完成 build → verify 过渡:
node "$COMET_GUARD" <change-name> build --apply状态文件自动更新为 phase: verify、verify_result: pending,然后进入验证。
复用 /comet-verify,由 comet-verify 的规模评估决定轻量或完整验证。
立即执行: 使用 Skill 工具加载 comet-verify 技能。禁止跳过此步骤。
带 delta spec 的验证分流:tweak 接受 delta spec 作为正常产物。若本次 change 创建了 delta spec,进入 comet-verify 前显式设置完整验证模式,走 OpenSpec 原生验证(openspec-verify-change)以覆盖 delta spec 一致性:
node "$COMET_STATE" set <change-name> verify_mode full无 delta spec 的 tweak 通常满足轻量验证条件(≤ 3 tasks、改动文件数低于 scale 阈值),由 comet-verify 的规模评估选择轻量验证路径(6 项快速检查)。若用户希望增加审查,可在验证前运行 node "$COMET_STATE" set <name> review_mode standard 或 thorough。
验证通过后,按 /comet-verify 的规则将 .comet.yaml 的 verify_result 记录为 pass,归档前不得跳过该状态。验证通过后仍必须进入 /comet-archive 的归档前最终确认,不得自动运行归档脚本。
复用 /comet-archive。归档前必须满足 .comet.yaml 中 verify_result: pass,并等待 /comet-archive 的归档前最终确认。
立即执行: 使用 Skill 工具加载 comet-archive 技能进行归档。禁止跳过此步骤。
<IMPORTANT>
Tweak 流程默认 **一次性连续执行**。调用 `/comet-tweak` 后,agent 在 tweak 自有步骤间自动推进,不主动停顿。**例外**:若 `auto_transition: false`,则在每个 phase 边界(build/verify/archive 之间)停下,由用户手动运行下一阶段命令——此时连续执行降级为逐阶段手动推进,详见下方「自动衔接下一阶段」。但无论 `auto_transition` 取何值,以下情况都必须暂停等待用户确认:
/comet 流程执行顺序:快速开启 → 构建(含升级判定检查)→ 验证 → 归档 → 完成
每个阶段完成后立即进入下一阶段。阶段内部仍必须按上文要求调用对应 Comet/OpenSpec/Superpowers skill,被调用的 skill 如有自己的用户决策点,按该 skill 规则执行。
</IMPORTANT>
tweak 的升级判定只决定是否从轻量预设转为 full;delta spec 本身不是升级理由,文件数不自动升级,comet-state scale 只决定验证轻重。
若由 /comet 入口传入 intent frame,tweak 在 build 前只复核 risk_signal 和升级信号:新增 capability、public API、schema 变更、跨模块协调或深层架构问题。命中时进入现有升级决策点;delta spec 仍是 tweak 的正常产物,不因存在 delta spec 自动升级;不得重新实现入口意图识别。
持续检查以下质变信号:跨模块协调修改、需要新增 capability、数据库 schema 变更、引入新的 public API、触及深层架构问题;以及 tweak 特有信号:需要拆分为多个 OpenSpec changes。命中任一信号时,agent 不得自行升级或自行判定可继续。
文件数 tripwire 仅作提示:改动文件数超过提示阈值(如 > 6 个文件)时,也交给用户决定继续 tweak 还是升级 full;文件数多不等于质变。tweak 常伴随 delta spec 或配置调整,波及面天然比 bug 修复宽,故提示阈值高于 hotfix。
命中质变信号或文件数 tripwire 时,必须按 comet/reference/decision-point.md 的协议暂停并等待用户明确选择。不得直接进入 /comet-design,不得自动补充 Design Doc。
用户选择升级(选项 B)后,使用状态机合法的升级通道,单条命令完成预设流程 → full 转换并回退到 design 阶段:
node "$COMET_STATE" transition <name> preset-escalate该命令原子地把 workflow/classic_profile 置为 full、phase 回退到 design、清空 design_doc(满足 comet-design 入口要求)。然后在当前 change 基础上补充 Design Doc:立即使用 Skill 工具加载 comet-design skill,后续正常走完整流程。
用户选择继续(选项 A)时,继续 tweak 流程,并记录用户确认继续的原因。
node "$COMET_GUARD" <change-name> build --apply,verify → archive 前按 /comet-verify 规则运行 node "$COMET_GUARD" <change-name> verify --apply按 comet/reference/auto-transition.md 执行。关键命令:
node "$COMET_STATE" next <name>NEXT: auto → 调用 SKILL 指向的 skill 继续 tweak 流程(phase: build 返回 comet-tweak,verify 返回 comet-verify,archive 返回 comet-archive)NEXT: manual → 不要调用下一 skill,按 HINT 提示用户手动运行 /<SKILL>NEXT: done → 流程已完成,无需继续© rpamis, MIT.

Run `npx skills add rpamis/comet --skill comet-tweak -a claude-code`. Or copy the skill folder (eval/local/skills/benchmarks/040-beta/comet-tweak in rpamis/comet) into .claude/skills/comet-tweak in your project. Claude Code loads it when a task matches its description.
Run `npx skills add rpamis/comet --skill comet-tweak -a codex`. Or copy the skill folder (eval/local/skills/benchmarks/040-beta/comet-tweak in rpamis/comet) into .agents/skills/comet-tweak in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add rpamis/comet --skill comet-tweak -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/comet-tweak, .gemini/skills/comet-tweak, .github/skills/comet-tweak and .opencode/skills/comet-tweak in your project.
Going by SKILL.md and its folder, Comet Tweak needs the command-line tools its instructions call (node, mvn and npm).
SKILL.md contains no URLs. Its commands use npm, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Comet Tweak is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.6k tokens (SKILL.md is roughly 6.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
