About this skill

Effective Harnesses is a skill in liangdabiao/exa-research-mcp-skill (110 stars). Its SKILL.md is about 417 tokens, with 11 other files in the folder. No licence found.

Requirements

  • Pre-approved tools (allowed-tools): Read, Glob, Grep, Edit, Write, Bash, Task, AskUserQuestion

Workflow steps

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

  1. 检查当前目录是否存在 feature_list.json
  2. 读取 git log 了解项目历史
  3. 读取进度文件了解当前状态
  4. 选择最高优先级的未完成 feature
  5. 运行 init.sh 启动开发服务器
  6. 验证基础功能未被破坏

What it can do on your machine

Read from SKILL.md and the folder at commit 6a345be. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Glob
    • Grep
    • Edit
    • Write
    • Bash
    • Task
    • AskUserQuestion

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • npm

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

  • Network

    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.

  • 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

Effective Harnesses loads about 417 tokens when it runs. Until then it costs about 15 tokens; SKILL.md has 98 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~15
When it runs · the whole SKILL.md, loaded when a task matches
~417

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.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Glob, Grep, Edit, Write, Bash, Task, AskUserQuestion

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 98 words (~417 tokens).
