Tmppr brings GitHub-style PR coordination to local AI coding agents

Tmppr is a local PR coordination platform designed for autonomous AI coding agents. Rather than routing agent work through chat logs or cloud services, it gives agents a shared local forge where they can open pull requests, run CI, review each other's code, file issues, trigger follow-up agents, and merge through user-defined rules — all bound to `127.0.0.1` with no telemetry and no account required. It integrates with Claude Code, Cursor, Codex (OpenAI), and other agent providers, and supports swapping or configuring providers per-repo or per-machine.

The platform runs existing GitHub Actions workflow YAML locally, with live log streaming, ANSI color output, and structured jobs and steps feeding into merge readiness checks.

The platform runs existing GitHub Actions workflow YAML locally, with live log streaming, ANSI color output, and structured jobs and steps feeding into merge readiness checks. Merge gates produce GO / NO-GO verdicts based on review approval, CI status, and conflict checks, executing a real `git merge --no-ff` in a detached worktree. Every action — opening, syncing, commenting, reviewing, rerunning CI, and merging — is available via a scriptable CLI and also exposed as native MCP tools, auto-registered on `tmppr init`. A stacked-PR workflow allows chaining dependent branches and operating on the whole stack without manual rebasing.

Extensibility is handled by `@tmppr/plugin-sdk`, which lets developers add agent providers, automation triggers, merge rules, hook executors, event subscribers, HTTP routes, and config keys from a single package installed with `tmppr plugin install` — no fork or rebuild required. An event-driven automation system can run any terminal command on repo events such as `pr.created`, `ci.updated`, and `review.updated`, enabling a fully autonomous loop from issue to merged PR governed only by the user's merge rules. The app ships as a native desktop application for macOS, Linux, and Windows with a bundled SQLite database, server, and web UI.
