About this skill

Strategic Compact is a skill in affaan-m/ECC (277k stars). Its SKILL.md is about 943 tokens, and copies of it appear in 3 other owners' repositories. Licence: MIT.

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. 跟踪工具调用 — 统计会话中的工具调用次数
  2. 阈值检测 — 在可配置的阈值处建议压缩（默认：50次调用）
  3. 定期提醒 — 达到阈值后，每25次调用提醒一次

What it can do on your machine

Read from SKILL.md and the folder at commit 2d515e4. 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 (its code samples are json).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • x.com

    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

Strategic Compact loads about 943 tokens when it runs. Until then it costs about 14 tokens; SKILL.md has 202 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~14
When it runs · the whole SKILL.md, loaded when a task matches
~943

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 passed

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.

建议在逻辑间隔处手动压缩上下文，以在任务阶段中保留上下文，而非任意的自动压缩。
origin
ECC

战略精简技能

建议在你的工作流程中的战略节点手动执行 /compact，而不是依赖任意的自动精简。

何时激活

  • 运行长时间会话，接近上下文限制时（200K+ tokens）
  • 处理多阶段任务时（研究 → 规划 → 实施 → 测试）
  • 在同一会话中切换不相关的任务时
  • 完成一个主要里程碑并开始新工作时
  • 当响应变慢或连贯性下降时（上下文压力）

为何采用战略精简？

自动精简会在任意时间点触发：

  • 通常在任务中途，丢失重要上下文
  • 无法感知逻辑任务边界
  • 可能中断复杂的多步骤操作

在逻辑边界进行战略精简：

  • 探索之后，执行之前 — 压缩研究上下文，保留实施计划
  • 完成里程碑之后 — 为下一阶段重新开始
  • 在主要上下文切换之前 — 在开始不同任务前清理探索上下文

工作原理

suggest-compact.js 脚本在 PreToolUse (Edit/Write) 时运行，并且：

  1. 跟踪工具调用 — 统计会话中的工具调用次数
  2. 阈值检测 — 在可配置的阈值处建议压缩（默认：50次调用）
  3. 定期提醒 — 达到阈值后，每25次调用提醒一次

钩子设置

作为插件安装？ 无需任何设置。插件的 hooks/hooks.json 已经注册了 suggest-compact.js（钩子 ID pre:edit-write:suggest-compact，在 standard 和 strict 钩子配置档中生效）。不要把下面的代码块复制到 ~/.claude/settings.json — 插件安装中不存在 ~/.claude/scripts/，并且重复注册插件钩子会导致双重执行。

如果是手动安装（./install.sh），添加到你的 ~/.claude/settings.json：

json
{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Edit",
        "hooks": [{ "type": "command", "command": "node ~/.claude/scripts/hooks/suggest-compact.js" }]
      },
      {
        "matcher": "Write",
        "hooks": [{ "type": "command", "command": "node ~/.claude/scripts/hooks/suggest-compact.js" }]
      }
    ]
  }
}

配置

环境变量：

  • COMPACT_THRESHOLD — 首次建议前的工具调用次数（默认：50）

压缩决策指南

使用此表来决定何时压缩：

阶段转换压缩？原因
研究 → 规划是研究上下文很庞大；规划是提炼后的输出
规划 → 实施是规划已保存在 TodoWrite 或文件中；释放上下文以进行编码
实施 → 测试可能如果测试引用最近的代码则保留；如果要切换焦点则压缩
调试 → 下一项功能是调试痕迹会污染不相关工作的上下文
实施过程中否丢失变量名、文件路径和部分状态代价高昂
尝试失败的方法之后是在尝试新方法之前，清理掉无效的推理过程

压缩后保留的内容

了解哪些内容会保留有助于您自信地进行压缩：

保留的内容丢失的内容
CLAUDE.md 指令中间的推理和分析
TodoWrite 任务列表您之前读取过的文件内容
记忆文件 (~/.claude/memory/)多轮对话的上下文
Git 状态（提交、分支）工具调用历史和计数
磁盘上的文件口头陈述的细微用户偏好

最佳实践

  1. 规划后压缩 — 一旦计划在 TodoWrite 中最终确定，就压缩以重新开始
  2. 调试后压缩 — 在继续之前，清理错误解决上下文
  3. 不要在实施过程中压缩 — 为相关更改保留上下文
  4. 阅读建议 — 钩子告诉您何时，您决定是否
  5. 压缩前写入 — 在压缩前将重要上下文保存到文件或记忆中
  6. 使用带摘要的 /compact — 添加自定义消息：/compact Focus on implementing auth middleware next

令牌优化模式

触发表惰性加载

不在会话开始时加载完整的技能内容，而是使用一个将关键词映射到技能路径的触发表。技能仅在触发时加载，可将基线上下文减少 50% 以上：

触发词技能加载时机
"test", "tdd", "coverage"tdd-workflow用户提及测试时
"security", "auth", "xss"security-review涉及安全相关工作时
"deploy", "ci/cd"deployment-patterns涉及部署上下文时
上下文组合感知

监控哪些内容正在消耗你的上下文窗口：

  • CLAUDE.md 文件 — 始终加载，需保持精简
  • 已加载技能 — 每个技能增加 1-5K 令牌
  • 对话历史 — 随每次交流增长
  • 工具结果 — 文件读取、搜索结果会增加体积
重复指令检测

常见的重复上下文来源：

  • 相同的规则同时出现在 ~/.claude/rules/ 和项目 .claude/rules/ 中
  • 技能重复了 CLAUDE.md 的指令
  • 多个技能覆盖了重叠的领域
上下文优化工具
  • token-optimizer MCP — 通过内容去重实现 95% 以上的自动令牌减少
  • context-mode — 上下文虚拟化（已演示从 315KB 减少到 5.4KB）

  • 记忆持久化钩子 — 用于在压缩后保留状态
  • continuous-learning 技能 — 在会话结束前提取模式

To copy it by hand, put the folder in .cursor/skills/strategic-compact, .gemini/skills/strategic-compact, .github/skills/strategic-compact and .opencode/skills/strategic-compact in your project.

What does Strategic Compact need to run?

SKILL.md names no scripts, command-line tools or credentials: Strategic Compact is instructions for the agent only.

Does Strategic Compact access the network?

SKILL.md names 1 domain. As links in the text: x.com. This is read from the text; nothing was executed.

Is Strategic Compact safe to install?

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.
