What does it do?
POSH gives developers and their coding agents local, offline copies of the documentation for the exact Ruby gem versions a project uses. Running posh sync inside the project downloads matching docsets, and a free terminal browser lets you search and read them. The paid agent tools add a CLI and a local MCP server, so an agent can look up one method and receive a short Markdown section rather than a whole web page.
Who is it for?
Ruby and Rails developers on macOS or Linux who use coding agents and are tired of those agents guessing at APIs from outdated or wrong-version docs.
When would you use it?
- Upgrading a gem: Sync after bumping Nokogiri or Rails so your agent reads the methods for the version in your lockfile, not an older release.
- Working offline: Search and read synced docs in the terminal on a plane or a weak connection, because lookups never touch the network after a sync.
- Saving agent context: Point an MCP-capable agent at the local server so each lookup returns a half-kilobyte section instead of hundreds of kilobytes of page.
Why pay for it?
Agents burn tokens and make mistakes when they read a full documentation page or the wrong version, and POSH hands them a small slice that matches your project. The maker builds docsets in an isolated machine and scans them for prompt injection, so agents treat the text strictly as data. The terminal reader is free, and the agent tools are a flat subscription with no per-request fees and a 14-day trial.
What should you know?
- Agent tools normally cost €7 a month or €60 a year. With code BLACKFRIDAY2026 they are €4.90 a month or €42 a year, and that rate holds while the subscription continues.
- The Black Friday code is for new subscriptions only and runs until December 2, 2026.
- POSH supports Ruby today, with Python and Go planned, and installs through Homebrew, the AUR or a GitHub release.
