Quick Start

# 1. Install for your AI tool
ptk init -g                     # Claude Code / Copilot (default)
ptk init -g --gemini            # Gemini CLI
ptk init -g --codex             # Codex (OpenAI)
ptk init -g --agent cursor      # Cursor
ptk init --agent windsurf       # Windsurf
ptk init --agent cline          # Cline / Roo Code

# 2. Restart your AI tool, then test
git status  # Automatically rewritten to ptk git status

The hook transparently rewrites Bash commands (e.g., git status -> ptk git status) before execution. Claude never sees the rewrite, it just gets compressed output.

Important: the hook only runs on Bash tool calls. Claude Code built-in tools like Read, Grep, and Glob do not pass through the Bash hook, so they are not auto-rewritten. To get PTK's compact output for those workflows, use shell commands (cat/head/tail, rg/grep, find) or call ptk read, ptk grep, or ptk find directly.

Windows / PowerShell agents: run ptk hooks init --shell powershell (or ptk hooks hook claude --shell powershell) to configure the PowerShell hookCommand. The generated snippet evaluates $Env:CMD, routes it through ptk rewrite, and writes the rewritten command only when PTK supports it; otherwise it prints the original command. Restart the agent after installing so the new hook takes effect.

How It Works

  Without ptk:                                    With ptk:

  Claude  --git status-->  shell  -->  git         Claude  --git status-->  PTK  -->  git
    ^                                   |            ^                      |          |
    |        ~2,000 tokens (raw)        |            |   ~200 tokens        | filter   |
    +-----------------------------------+            +------- (filtered) ---+----------+

Four strategies applied per command type:

1. Smart Filtering - Removes noise (comments, whitespace, boilerplate)
2. Grouping - Aggregates similar items (files by directory, errors by type)
3. Truncation - Keeps relevant context, cuts redundancy
4. Deduplication - Collapses repeated log lines with counts

Auto-Rewrite Hook

The most effective way to use ptk. The hook transparently intercepts Bash commands and rewrites them to ptk equivalents before execution.

Result: 100% ptk adoption across all conversations and subagents, zero token overhead.

Scope note: this only applies to Bash tool calls. Claude Code built-in tools such as Read, Grep, and Glob bypass the hook, so use shell commands or explicit ptk commands when you want PTK filtering there.

Setup

ptk init -g                 # Install hook + PTK.md (recommended)
ptk init -g --opencode      # OpenCode plugin (instead of Claude Code)
ptk init -g --auto-patch    # Non-interactive (CI/CD)
ptk init -g --hook-only     # Hook only, no PTK.md
ptk init --show             # Verify installation

After install, restart Claude Code.

Supported AI Tools

PTK supports 10 AI coding tools. Each integration transparently rewrites shell commands to ptk equivalents for 60-90% token savings.

| Jules (Google Cloud) | ptk init --agent jules | .julesrules + ptk-setup.sh | | Baton | ptk init --agent baton | Alias for Jules integration | | Cursor | ptk init -g --agent cursor | preToolUse hook (bash/ps1) | | Gemini CLI | ptk init -g --gemini | BeforeTool hook (bash/ps1) | | Codex | ptk init -g --codex | AGENTS.md + PTK.md instructions | | Windsurf | ptk init --agent windsurf | .windsurfrules (project-scoped) | | Cline / Roo Code | ptk init --agent cline | .clinerules (project-scoped) | | Claude Code | ptk init -g | PreToolUse hook (bash) | | GitHub Copilot | ptk init -g --copilot | PreToolUse hook (json/prompt) | | PowerShell Agents | ptk init --shell powershell | Unified PowerShell hook |

Claude Code (default)

ptk init -g                 # Install hook + PTK.md
ptk init -g --auto-patch    # Non-interactive (CI/CD)
ptk init --show             # Verify installation
ptk init -g --uninstall     # Remove

GitHub Copilot (VS Code + CLI)

ptk init -g --copilot         # Install hook + instructions

Creates .github/hooks/ptk-rewrite.json (PreToolUse hook) and .github/copilot-instructions.md (prompt-level awareness).

The hook (ptk hook copilot) auto-detects the format:

• VS Code Copilot Chat: transparent rewrite via updatedInput (same as Claude Code)
• Copilot CLI: deny-with-suggestion (CLI does not support updatedInput yet — see copilot-cli#2013)

Cursor

ptk init -g --agent cursor

Creates ~/.cursor/hooks/ptk-rewrite.sh + patches ~/.cursor/hooks.json with preToolUse matcher. Works with both Cursor editor and cursor-agent CLI.

Gemini CLI

ptk init -g --gemini
ptk init -g --gemini --uninstall

Creates ~/.gemini/hooks/ptk-hook-gemini.sh + patches ~/.gemini/settings.json with BeforeTool hook.

Codex (OpenAI)

ptk init -g --codex          # ~/.codex/PTK.md + ~/.codex/AGENTS.md
ptk init --codex             # ./PTK.md + ./AGENTS.md in the current directory
ptk hook codex -g            # same as global install above

Creates PTK.md (usage + examples for Bash and PowerShell) and patches AGENTS.md with an @PTK.md reference, matching the RTK Codex flow. Legacy <!-- rtk-instructions --> blocks and @RTK.md lines in AGENTS.md are migrated away on install. Restart Codex CLI after installing.

Windsurf

ptk init --agent windsurf

Creates .windsurfrules in the current project. Cascade reads rules and prefixes commands with ptk.

Cline / Roo Code

ptk init --agent cline

Creates .clinerules in the current project. Cline reads rules and prefixes commands with ptk.

OpenCode

ptk init -g --opencode

Creates ~/.config/opencode/plugins/ptk.ts. Uses tool.execute.before hook.

OpenClaw

openclaw plugins install ./openclaw

Plugin in openclaw/ directory. Uses before_tool_call hook, delegates to ptk rewrite.

Mistral Vibe (planned)

Blocked on upstream BeforeToolCallback support (mistral-vibe#531, PR #533). Tracked in #800.

Configuration

Config File

~/.config/ptk/config.toml (macOS: ~/Library/Application Support/ptk/config.toml):

[tracking]
database_path = "/path/to/custom.db"  # default: ~/.local/share/ptk/history.db

[hooks]
exclude_commands = ["curl", "playwright"]  # skip rewrite for these

[tee]
enabled = true          # save raw output on failure (default: true)
mode = "failures"       # "failures", "always", or "never"
max_files = 20          # rotation limit

Tee: Full Output Recovery

When a command fails, PTK saves the full unfiltered output so the LLM can read it without re-executing:

FAILED: 2/15 tests
[full output: ~/.local/share/ptk/tee/1707753600_cargo_test.log]

Uninstall

ptk init -g --uninstall     # Remove hook, PTK.md, settings.json entry
cargo uninstall ptk          # Remove binary
brew uninstall ptk           # If installed via Homebrew

Privacy & Telemetry

PTK collects anonymous, aggregate usage metrics once per day, enabled by default. This helps prioritize development. See opt-out options below.

What is collected:

• Device hash (salted SHA-256 — per-user random salt stored locally, not reversible)
• PTK version, OS, architecture
• Command count (last 24h) and top command names (e.g. "git", "cargo" — no arguments, no file paths)
• Token savings percentage

What is NOT collected: source code, file paths, command arguments, secrets, environment variables, or any personally identifiable information.

Opt-out (any of these):

# Environment variable
export PTK_TELEMETRY_DISABLED=1
