pcr — Prompt & Code Review CLI

Capture the prompts your team sends to AI coding assistants. Review them like a code review.

What this is

pcr is a local CLI that watches the AI coding sessions you already have running (Cursor, Claude Code, VS Code Copilot Chat), captures every prompt with the right project / branch / commit / model attribution, and lets you bundle and push them to pcr.dev where your team reviews them alongside the diff.

The CLI in this repo is open source under Apache 2.0. The dashboard at pcr.dev is a hosted product; the CLI works against a local-only store without it.

Install

npm install -g pcr-dev                                 # any platform, Node ≥ 16
brew install pcr-developers/pcr/pcr                    # macOS · Linux

Standalone binaries for every supported platform are on the Releases page.

Supported platforms: macOS arm64 · macOS x64 · Linux x64 · Windows x64.

Quickstart

pcr login                                # one-time browser auth (skip for local-only use)
cd ~/code/your-repo
pcr init                                 # register the current git repo
pcr start                                # leave running while you work in your editor
pcr bundle "auth refactor"               # opens the TUI: pick drafts, press b → enter
pcr push                                 # upload to pcr.dev for team review

For per-command examples, run pcr <cmd> --help or browse pcr.dev/docs.

How it works

The supported AI tools each write session transcripts to disk as you work. pcr start watches those files, attributes every prompt to the right project / branch / commit, and saves them locally. Nothing leaves your machine until you explicitly run pcr push.

Cursor / Claude Code / Copilot
       │  (writes session files to disk — already happens)
       ▼
   pcr start ─────────▶ ~/.pcr-dev/drafts.db
       │
       ▼
   pcr bundle "name"                  (TUI: select drafts, press b → enter)
       │
       ▼
   pcr push      ────▶ pcr.dev      (reviewers comment on prompts as they would on code)

What gets captured

Source	Captured
Cursor	Agent / ask / plan turns, model, mode, file attribution, periodic git diff
Claude Code	Full prompt + response, every tool call, permission mode, project
VS Code Copilot Chat	Prompt + response, tool calls, including unsaved-window chats

Each prompt is annotated with project, branch, commit, model, mode, and (when available) the diff it produced.

Commands

Command	What it does
pcr login / pcr logout	Authenticate / sign out
pcr init	Register the current git repo
pcr start	Live capture (TUI by default; --plain for line mode)
pcr status	Auth · projects · pipeline overview
pcr log	Captured prompts and bundles for the current repo
pcr show <n>	Open one draft in the full-screen browser
pcr bundle [name]	Open the interactive bundle browser (name pre-fills the modal)
pcr push	Upload sealed bundles to pcr.dev
pcr pull <id>	Restore a pushed bundle to local drafts
pcr gc	Reclaim local-store space
pcr help	Interactive command browser

Run pcr <cmd> --help for examples. Full reference at pcr.dev/docs.

Live dashboard

pcr start runs a ratatui TUI showing every watcher's status, your registered projects, the live event log, and the draft → bundled → pushed pipeline:

Falls back to plain stderr lines when stdout isn't a TTY, CI=1, NO_COLOR is set, or --plain is passed.

CI / agent use

pcr is built to behave correctly whether a human or an LLM is at the terminal.

• --plain disables the TUI; output stays on stderr.
• --json emits machine-readable JSON on stdout.
• Auto-detects non-TTY stdio, CI, NO_COLOR, CURSOR_AGENT, etc., and behaves as if --plain were passed.
• Stable exit codes: 0 success · 2 usage · 10 auth required · 11 network · 13 not found · 40 interactive unavailable · 50 not implemented.

pcr --json status
pcr --plain bundle "agent run" --select all && pcr --plain push   # plain mode keeps --select for scripts

Privacy

• Everything lives in ~/.pcr-dev/ until you explicitly run pcr push.
• Reads session files Cursor / Claude Code / Copilot already write to disk. No clipboard access, no keylogging, no editor extension, no patches to your AI tool.
• TLS-only push (reqwest + rustls); per-user CLI tokens; row-level security on the server side.
• No telemetry beyond what you push.

Build from source

Rust 1.82 or newer (MSRV). The dev rust-toolchain.toml pins a current stable release; rustup will install it on demand. Zero C dependencies — rusqlite uses the bundled SQLite, reqwest uses rustls-tls. A clean checkout compiles offline.

git clone https://github.com/pcr-developers/cli.git
cd cli
cargo build --release -p pcr-cli
cargo test --workspace
./target/release/pcr help

The npm package ships as a Node native addon (a .node file loaded into node.exe) rather than a standalone executable, so it works under Windows AppLocker / WDAC policies that block unsigned executables in user-writable directories. See crates/pcr-napi/NPM-INTERNALS.md for the technical details.

Contributing

Issues and PRs welcome. Please read AGENTS.md first — it documents the line-mode output discipline (must stay byte-stable for golden tests), source-watcher invariants, and the conventions for both human and AI contributors.

Good first issues are tagged good first issue. Architectural changes should start with a discussion thread before a PR.
