plan-phase
Produce an executable plan for a bounded slice or phase.
Best use case
plan-phase is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Produce an executable plan for a bounded slice or phase.
Teams using plan-phase should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Purpose Create a plan that an executor can implement without reinterpretation. # Read First - `.agents/AGENTS.md` - `.agents/workflows/plan-phase.md` # Use When - Work is broader than trivial - Tests, scope, or verification need explicit sequencing # Output - Bounded plan with test-first execution path # Prohibitions - No implementation before planning when the work is non-trivial
