What it does
Context Budget is an agent skill from affaan-m/ECC. 审核Claude Code上下文窗口在代理、技能、MCP服务器和规则中的消耗情况。识别膨胀、冗余组件，并提供优先的令牌节省建议。
Its SKILL.md is about 710 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, covering Context engineering. It works with Model Context Protocol. The repository describes itself as: The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond. The licence is MIT.
When your agent uses it
- Tasks that involve Context engineering
Example prompts
- “/context-budget”
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.
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
Context Budget loads about 709 tokens when it runs. Until then it costs about 20 tokens; SKILL.md has 148 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 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.

上下文预算
分析 Claude Code 会话中每个已加载组件的令牌开销，并提供可操作的优化建议以回收上下文空间。
使用时机
- 会话性能感觉迟缓或输出质量下降
- 你最近添加了许多技能、代理或 MCP 服务器
- 你想知道实际有多少上下文余量
- 计划添加更多组件，需要知道是否有空间
- 运行
/context-budget命令（本技能为其提供支持）
工作原理
阶段 1：清单
扫描所有组件目录并估算令牌消耗：
代理 (agents/*.md)
- 统计每个文件的行数和令牌数（单词数 × 1.3）
- 提取
description前言长度 - 标记：文件 >200 行（繁重），描述 >30 词（臃肿的前言）
技能 (skills/*/SKILL.md)
- 统计 SKILL.md 的令牌数
- 标记：文件 >400 行
- 检查
.agents/skills/中的重复副本 — 跳过相同副本以避免重复计数
规则 (rules/**/*.md)
- 统计每个文件的令牌数
- 标记：文件 >100 行
- 检测同一语言模块中规则文件之间的内容重叠
MCP 服务器 (.mcp.json 或活动的 MCP 配置)
- 统计配置的服务器数量和工具总数
- 估算模式开销约为每个工具 500 令牌
- 标记：工具数 >20 的服务器，包装简单 CLI 命令的服务器 (
gh,git,npm,supabase,vercel)
CLAUDE.md（项目级 + 用户级）
- 统计 CLAUDE.md 链中每个文件的令牌数
- 标记：合并总数 >300 行
阶段 2：分类
将每个组件归入一个类别：
| 类别 | 标准 | 操作 |
|---|---|---|
| 始终需要 | 在 CLAUDE.md 中被引用，支持活动命令，或匹配当前项目类型 | 保留 |
| 有时需要 | 特定领域（例如语言模式），未在 CLAUDE.md 中引用 | 考虑按需激活 |
| 很少需要 | 无命令引用，内容重叠，或无明显的项目匹配 | 移除或延迟加载 |
阶段 3：检测问题
识别以下问题模式：
- 臃肿的代理描述 — 前言中描述 >30 词，会在每次任务工具调用时加载
- 繁重的代理 — 文件 >200 行，每次生成时都会增加任务工具的上下文
- 冗余组件 — 重复代理逻辑的技能，重复 CLAUDE.md 的规则
- MCP 超额订阅 — >10 个服务器，或包装了可免费使用的 CLI 工具的服务器
- CLAUDE.md 臃肿 — 冗长的解释、过时的部分、本应成为规则的指令
阶段 4：报告
生成上下文预算报告：
上下文预算报告
═══════════════════════════════════════
总预估开销：约 XX,XXX 个词元
上下文模型：Claude Sonnet (200K 窗口)
有效可用上下文：约 XXX,XXX 个词元 (XX%)

示例
基本审计
/context-budget
技能：扫描设置 → 16个代理（12,400个令牌），28个技能（6,200），87个MCP工具（43,500），2个CLAUDE.md（1,200）
标记：3个重型代理，14个MCP服务器（3个可替换为CLI）
最高节省：移除3个MCP服务器 → -27,500个令牌（减少47%开销）详细模式
/context-budget --verbose
技能：完整报告 + 按文件细目显示 planner.md（213 行，1,840 个令牌），
MCP 工具列表及每个工具的大小，重复规则行并排显示扩容前检查
User: 我想再添加5个MCP服务器，有空间吗？
Skill: 当前开销33% → 添加5个服务器（约50个工具）会增加约25,000个tokens → 开销将升至45%
建议：先移除2个可用CLI替代的服务器以保持在40%以下最佳实践
- 令牌估算：对散文使用
words × 1.3，对代码密集型文件使用chars / 4 - MCP 是最大的杠杆：每个工具模式约消耗 500 令牌；一个 30 个工具的服务器开销超过你所有技能的总和
- 代理描述始终加载：即使代理从未被调用，其描述字段也存在于每个任务工具上下文中
- 详细模式用于调试：需要精确定位导致开销的确切文件时使用，而非用于常规审计
- 变更后审计：添加任何代理、技能或 MCP 服务器后运行，以便及早发现增量
