Implementation Execution
Overview
Execute development tasks from the task list against the specification and constitution. Produces code, tests, and configuration artifacts with progressive validation. Independent tasks execute in parallel; dependent tasks execute sequentially respecting the dependency graph.
When to Use
- After task list is approved and analysis confirms readiness
- When implementing feature code against a specification
- When running per-task tests during implementation
- When validating implementation against specification requirements
Key Principle
Every line of code must trace back to a specification requirement. Code quality must meet constitution standards. Tests must verify acceptance criteria from the task definition.
Process
- Prepare environment - Scaffold directories and configuration
- Execute independent tasks - Parallel execution for tasks without dependencies
- Execute dependent tasks - Sequential execution respecting dependency graph
- Run per-task tests - Verify each task's acceptance criteria
- Validate against spec - Check requirement coverage and story satisfaction
- Run integration tests - Cross-component testing
- Human review - Approve implementation before quality checklist

Recommended Agent Skills
Expand your agent's capabilities with these related and highly-rated skills.
gsd-tools
Central utility skill for GSD operations. Provides config parsing, slug generation, timestamps, path operations, and orchestrates calls to other specialized skills. Acts as the unified entry point that the original gsd-tools.cjs provided via its lib/ modules (commands, config, core, init).
model-profile-resolution
Resolve model profile (quality/balanced/budget) at orchestration start and map agents to specific models. Enables cost/quality tradeoffs by selecting appropriate AI models for each agent role.
verification-suite
Plan structure validation, phase completeness checks, reference integrity verification, and artifact existence confirmation. Provides the structured verification layer ensuring GSD artifacts are well-formed and complete.
state-management
STATE.md reading, writing, and field-level updates. Provides cross-session state persistence via .planning/STATE.md with structured fields for current task, completed phases, blockers, decisions, and quick tasks.
git-integration
Git commit patterns, formats, and conventions for GSD methodology. Provides atomic commits per task, structured commit messages, planning file commits, branch management, and milestone tag operations.
frontmatter-parsing
YAML frontmatter parsing and manipulation for .planning/ documents. Provides read, write, update, query, and validation operations on frontmatter blocks in GSD markdown artifacts.
