intelligent-terminal: Instructions file for Claude Code

.github/instructions/hooks.instructions.md

intelligent-terminal hooks.instructions.md is an instructions file for Claude Code, GitHub Copilot from microsoft/intelligent-terminal. It costs 5,380 tokens per session, scanned D, original, MIT.

Guidance for creating hooks: small commands or scripts that run at defined points in an agent session. It covers their configuration, event matching, input, output, and exit codes.

In plain words
What is it for?
Authoring hooks that inspect or control tool use, registering them for lifecycle events, and providing shell or PowerShell implementations.
Why use it?
It helps hooks stay predictable, quick, and clear about their side effects. It also shows how to organize hook configuration and scripts in a repository.

Written for Claude Code and GitHub Copilot: PreToolUse hook event, but also a Copilot instructions file. Also seen: reads .claude/ paths; mentions subagents; mentions Claude Code.

This is microsoft/intelligent-terminal's own configuration. It tells Claude Code and GitHub Copilot how to work on intelligent-terminal itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything intelligent-terminal configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is "bash": "python3 ./.github/hooks/scripts/check.py",.

About the project

Intelligent Terminal is an experimental fork of Windows Terminal that adds native support for AI agents through the Agent Client Protocol. It is for Windows users who want to manage compatible agent command-line tools alongside terminal tabs, profiles, themes, shells, and keyboard shortcuts, and the catalogue entries provide instructions, skills, hooks, and a plugin for working with it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade D, and why

intelligent-terminal hooks.instructions.md scanned grade D with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

How it starts

The opening of the file, as written. The whole thing — 598 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Hook Authoring Guidelines

Hooks are small, deterministic commands or scripts that run at specific lifecycle events. An awesome hook does one clear job, runs quickly, and makes its side effects explicit.

Folder Structure

A GitHub Copilot hook lives in .github/hooks/ inside your repository:

.github/
└── hooks/
    ├── block-dangerous-commands.json   ← hook config (which event, which script, options)
    └── scripts/
        ├── block-dangerous-commands.sh  ← Bash implementation
        └── block-dangerous-commands.ps1 ← PowerShell implementation (optional if Bash-only)

You can have multiple .json files — each one registers hooks for one or more events. The host loads all of them.

The Config File

Each .json file maps events to an array of hook entries.

  • Command hooks (type: "command"): run a local script. The host passes event JSON on stdin, your script responds through exit code and stdout.

Config example

{
  "version": 1,
  "hooks": {
    "preToolUse": [
      {
        "matcher": "bash",
        "type": "command",
        "bash": "./.github/hooks/scripts/block-dangerous-commands.sh",
        "powershell": "./.github/hooks/scripts/block-dangerous-commands.ps1",
        "cwd": ".",
        "timeoutSec": 5,
        "env": {
          "BLOCK_MODE": "deny"
        }
      }
    ]
  }
}

Config fields

Field Required What it does
type yes "command" for scripts
matcher no Host-level filter — hook only fires when the tool name matches this value (e.g. "bash", "powershell", "edit", "create"). Locally verified working in Copilot CLI v1.0.36; not yet used in repo hook samples.
bash one or both Command line invoked on Unix / Bash-capable hosts
powershell one or both Command line invoked on Windows / PowerShell-capable hosts
cwd no Working directory, relative to repo root
timeoutSec no Max seconds before the host kills the process (default 30)
env no Extra process environment variables passed to the script

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

intelligent-terminal hooks.instructions.md is an instructions file published in the GitHub repository microsoft/intelligent-terminal (2,074 stars, last pushed today), licensed MIT. It adds 5,380 tokens to every session, about $0.0215 per session on Opus 5.5. A static security scan graded it D with 2 findings (reads agent configuration directories, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
