What it does

Control CLI is an agent skill from cursor/plugins, published by the product's own GitHub organization. Build or adapt a local harness to drive, inspect, and profile an interactive CLI or TUI without external services. Use for CLI UX checks, startup regressions, memory leaks, hangs, prompt flows, or terminal demos.

Its SKILL.md is about 1.1k 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 Development, covering Performance optimization. It works with tmux. The repository describes itself as: Cursor plugin specification and official plugins.

When your agent uses it

  • Startup regressions
  • Tasks that involve Performance optimization

Example prompts

  • “/control-cli”

Requirements

  • Python 3

Workflow steps

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

  1. Identify the command under test and the smallest reproducible workspace.
  2. Discover existing local harnesses: package scripts, e2e tests, demo recorders, expect scripts, or PTY helpers.
  3. If no harness exists, launch the CLI in an isolated terminal session with deterministic env vars.
  4. Capture the current screen before interacting.
  5. Send one action at a time: text, Enter, arrows, Escape, Ctrl-C, resize.
  6. Wait for a concrete screen pattern or prompt before the next action.
  7. Save the transcript and any profile artifacts.
  8. Kill the session cleanly.

What it can do on your machine

Read from SKILL.md and the folder at commit 9f451cf. 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 bash and python).

    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

Control CLI loads about 1.1k tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 456 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 456 words (~1,084 tokens).

“Use a repeatable local harness to exercise an interactive CLI instead of poking at it manually. First reuse the repo's own test/demo harness if it exists; otherwise assemble a temporary harness from standard local tools.”
