Deep Plan Skill

Research-validated planning that eliminates the gap between research assumptions and actual code. Orchestrates a 3-phase cycle: Discovery Research → Reality-Check Planning → Plan Verification.

Teams-compatible — works both from the main conversation (R010) and inside Agent Teams members. When used in Teams, the member directly executes the 3-phase workflow without Skill tool invocation.

Usage

/deep-plan <topic-or-issue>
/deep-plan "implement caching layer for API responses"
/deep-plan #325 new authentication system
/deep-plan Rust async runtime migration
