Emergency Hotfix Workflow
Donchitos/Claude-Code-Game-Studios
Runs an emergency fix process for severe bugs: a severity check, a written hotfix record, and a branch cut from the shipped release rather than main.
Switch Harness workflow mode (full/hotfix/tweak) and development phase (design/build/fix).

What it does
Harness Mode is an agent skill from k1ein-chen/Harness-Starter. Switch Harness workflow mode (full/hotfix/tweak) and development phase (design/build/fix). Use when the user wants to change the current working mode or phase.
Its SKILL.md is about 270 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: 一套成熟完善的开箱即用的 Claude Code Harness Engineering 模板。三层自动化（安全/感知/审查），集成 LSP、OpenSpec SDD 工作流和 AI 一键初始化。新项目和已有项目均可使用。 The licence is MIT.
When your agent uses it
- The user wants to change the current working mode
Example prompts
- “/harness-mode”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- 读取 .claude/.harness-state（不存在则创建默认值 {"phase":"build","mode":"full"}）
- 修改对应的 mode 或 phase 字段
- 更新 since 为当前时间
- 写入文件
- 回显新状态
What it can do on your machine
Read from SKILL.md and the folder at commit c211c43. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Harness Mode loads about 273 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 57 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.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:17
/harness-mode tweak → 微调模式，仅 .env 保护
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.

Harness Mode
管理 .claude/.harness-state，控制 Harness 的行为策略。
支持的命令
切换模式
/harness-mode full → 完整检查，所有规则生效
/harness-mode hotfix → 紧急修复，跳过行数/文件数检查
/harness-mode tweak → 微调模式，仅 .env 保护切换阶段
/harness-phase design → 设计阶段，宽松审查
/harness-phase build → 构建阶段，正常审查
/harness-phase fix → 修复阶段，收紧变更范围检查查看当前状态
/harness-status → 显示当前阶段和模式执行逻辑
当用户输入上述命令时：
- 读取
.claude/.harness-state（不存在则创建默认值{"phase":"build","mode":"full"}） - 修改对应的
mode或phase字段 - 更新
since为当前时间 - 写入文件
- 回显新状态
模式联动：
- 切换到
hotfix模式时，自动将 phase 设为fix - 切换到
tweak模式时，自动将 phase 设为design
示例
用户：/harness-mode hotfix
→ 写入 {"phase":"fix","mode":"hotfix","since":"2026-06-01T12:00:00Z"}
→ 回复：「已切换到热修复模式：阶段=fix, 模式=hotfix。将跳过行数/文件数检查。」
用户：/harness-status
→ 回复：「当前 Harness 状态：阶段=build, 模式=full (since 2026-06-01T10:00:00Z)」

When should I use Harness Mode?
Harness Mode fits situations like: the user wants to change the current working mode.
How do I install Harness Mode in Claude Code?
Run `npx skills add k1ein-chen/Harness-Starter --skill harness-mode -a claude-code`. Or copy the skill folder (.claude/skills/harness-mode in k1ein-chen/Harness-Starter) into .claude/skills/harness-mode in your project. Claude Code loads it when a task matches its description.
How do I install Harness Mode in Codex?

Can I use Harness Mode in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add k1ein-chen/Harness-Starter --skill harness-mode -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/harness-mode, .gemini/skills/harness-mode, .github/skills/harness-mode and .opencode/skills/harness-mode in your project.
What does Harness Mode need to run?
SKILL.md names no scripts, command-line tools or credentials: Harness Mode is instructions for the agent only.
Does Harness Mode access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Harness Mode safe to install?
Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
What licence does Harness Mode use?
Harness Mode is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Harness Mode use?
About 273 tokens (SKILL.md is roughly 1.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Harness Mode?
