speckit-implement

Automate project implementation by parsing tasks.md into Setup, Tests, Core, Integration, and Polish phases. The system executes dependency-aware task lists sequentially or in parallel, validates checklists, and handles hook execution to reduce manual coordination.

Phased task execution parses task markings to respect sequential and parallel rules, running tests before code. It tracks progress and halts immediately on non-parallel failures to ensure dependency-aware execution integrity throughout the plan.

Yes, you need a spec-kit .specify directory with associated artifacts like plan.md, tasks.md, and contracts. The execution process verifies these required artifacts are present and checks for appropriate ignore files before starting implementation.

Checklist enforcement scans checklist files to compute pass or fail status, pausing for user confirmation if any items are incomplete. This pre-execution validation ensures all checklist criteria are satisfied before phased implementation begins.

Pre-execution and post-execution extension hooks are detected by parsing .specify/extensions.yml. The system surfaces optional versus mandatory hooks without evaluating conditions, executing specified prerequisite scripts to ensure proper project setup.

Implementation halts on non-parallel failures to prevent dependent tasks from executing in an invalid state. The system tracks progress, marks completed tasks in tasks.md, and safely stops execution to avoid compounding errors across phases.
