Spec Execution

Overview

Executes a feature specification through 6 iterative phases with quality-gated convergence. Each phase builds on the previous, with improvement cycles triggered when quality falls below threshold.

Six Phases

Phase 1: Implementation

  • Read specification for requirements and architecture
  • Implement each requirement following project conventions
  • Add type definitions and JSDoc documentation
  • Implement error handling for all failure modes

Phase 2: Test Writing

  • Write unit tests for each module/function
  • Write integration tests for API boundaries
  • Cover all acceptance criteria from the specification
  • Test edge cases and error paths

Phase 3: Code Review

  • Verify all requirements are implemented
  • Check acceptance criteria are tested
  • Review architecture adherence
  • Assess code quality

Phase 4: Iterative Improvement

  • Address review findings
  • Fix failing tests
  • Resolve architecture deviations
  • Re-verify quality (convergence loop, max 3 cycles)

Phase 5: Atomic Commit

  • Group changes into logical atomic commits
  • Descriptive messages following project conventions
  • Separate production, test, and config changes
  • Include specification reference

Phase 6: Progress Tracking

  • Requirement completion percentage
  • Test coverage summary
  • Quality score report
  • Remaining work identification

Quality Gate

Quality threshold defaults to 80. If not met after max improvement cycles, a human breakpoint is triggered for review.

When to Use

  • /spec:execute [file]
    slash command
  • After spec creation when ready to implement
