Prime Radiant

streamlinear: the first Prime Radiant repo

Week of December 22, 2025 · Dec 22, 2025–Dec 28, 2025 · published Dec 28, 2025

This is where the company’s public record starts: the week prime-radiant-inc’s first repository, streamlinear, landed — a Model Context Protocol tool that hands an agent a clean interface to Linear. Around it, the obra ecosystem kept moving, with superpowers cutting two releases and outside contributors landing fixes across half a dozen repos.

prime-radiant-inc/streamlinear

A Model Context Protocol tool that gives a coding agent a clean interface to Linear.

14 commits

Fourteen commits from a standing start — the repo’s first commit through a working, npx-installable MCP tool. The arc: a searchIssues fix (use term, not query), a discoverability pass (me/help actions, better errors, and teams/states baked into the tool description at startup so an agent sees them without a round-trip), and npx packaging — a pre-commit hook that auto-builds and commits dist/, plus a bin field and shebang. Sole contributor: Jesse Vincent.

obra/superpowers

An agentic skills framework and software-development methodology.

10 commits 2 PRs +1,626 −31

Ten commits and two releases (v4.0.2, v4.0.3). The work sharpened the framework’s edges: slash commands made user-only via disable-model-invocation, agent-model inheritance fixed, git check-ignore adopted for worktree gitignore verification, and guidance added to the writing-skills and using-superpowers skills (automation-over-documentation, stronger handling of explicit skill requests). Jesse Vincent drove it; outside contributors egornomic and mycarrysun each landed a commit.

Also shipped

2 commits 1 PR +28 −4
