Agent OS

Agent OS (by Builder Methods) is a system for injecting codebase standards and writing better specs for spec-driven development. You drive it with slash commands: /plan-product lays out the product, /shape-spec turns a feature into a spec.

/plan-product writes committed markdown under agent-os/product/:

  • agent-os/product/mission.md
  • agent-os/product/roadmap.md
  • agent-os/product/tech-stack.md

/shape-spec (run in plan mode) gathers requirements into a spec doc. Both phases are pause points for PlanBridge.

Manual

Section titled “Manual”

After /plan-product, review the product docs:

/planbridge-open agent-os/product/mission.md
/planbridge-open agent-os/product/roadmap.md

After /shape-spec, review the spec it just wrote:

/planbridge-open the spec you just wrote

The agent revises the spec from your inline comments before any code is written.

Automatic

Section titled “Automatic”

To review each artifact without asking, append a snippet to your global agent instructions:

Terminal window
echo '
## Agent OS + PlanBridge


After `/plan-product` writes the product docs under `agent-os/product/`, or `/shape-spec` writes a spec, run `/planbridge-open` on the file instead of asking me to review it as text. Treat the returned annotations as my review feedback and revise before coding.
