What Execute Phase does

Execute Phase runs all plans in a phase using wave-based parallel execution with subagents. It discovers plans, analyzes dependencies, groups them into waves, and collects results while preserving checkpoints and verification gates.

Execute Phase is cataloged under AI Engineering on DirSkills. Execute Phase comes from a repository tagged claude-code, context-engineering, meta-prompting and spec-driven-development.

Documentation

README

Excerpt

Orchestrator stays lean: discover plans, analyze dependencies, group into waves, spawn subagents, collect results. Each subagent loads the full execute-plan context and handles its own plan.

Optional wave filter:

--wave N executes only Wave N for pacing, quota management, or staged rollout
phase verification/completion still only happens when no incomplete plans remain after the selected wave finishes

Flag handling rule:

The optional flags documented below are available behaviors, not implied active behaviors
A flag is active only when its literal token appears in $ARGUMENTS
If a documented flag is absent from $ARGUMENTS, treat it as inactive

This is the opening of the README. Read the full README on GitHub.
