Included Skills2

backchainskills/backchain/SKILL.md

Use when an implementation task needs a dependency-aware plan before coding: backward planner / backchain / precondition-first planning, dependency DAGs, elaborating incomplete plans, or scheduler-ready step graphs. Turns a natural-language coding request into a forward draft then backward-chaining enriched DAG with explicit unresolved risks, then directly calls the selected Until Loop to repeat dependency review until two consecutive trivial/no-change reviews.

plan-dispatcherskills/plan-dispatcher/SKILL.md

Use when executing or resuming an agreed dependency graph with one main dispatcher and parallel native workers: claim ready steps, preserve launch state, collect result evidence, verify outcomes, and identify successors. Planning belongs to Backchain or the caller; this skill executes the plan.
