Write minimal implementation to make failing tests pass. Use this agent when the craft skill dispatches an implementation task from a yak with agent-type 'agent-impl'. The agent writes implementation ONLY — never modifies test files. Applies a YAGNI simplification pass after tests pass. Reports GREEN gate status.

Execute non-TDD phase tasks like schema migrations, infrastructure setup, or configuration. Use this agent when the craft skill dispatches a task from a yak with agent-type 'no-test'. The agent executes the task as described and verifies the acceptance gate.

Fix implementation after validation finds failures. Use this agent when the craft skill creates a remediation yak with agent-type 'agent-remediate'. The agent fixes implementation code ONLY — never modifies test files. Receives failure output from the validation agent. Escalates to user after 2 failed attempts.

Write failing tests for a TDD phase. Use this agent when the craft skill dispatches a test-writing task from a yak with agent-type 'agent-test'. The agent writes tests ONLY — never implementation code. It receives a self-contained task context with file paths, test spec, and test command. Reports RED gate FAIL if tests pass immediately.

Run the full test suite and report results without modifying any files. Use this agent when the craft skill dispatches a validation task from a yak with agent-type 'agent-validate'. The agent runs tests, type-checks, and linting — all must exit 0 for the VALIDATE gate to pass. Reports only, never fixes.

Guides writing minimal Architecture Decision Records (ADRs). Use when recording architectural decisions, documenting design choices, capturing technical decisions with context and alternatives, or when user mentions ADR, architecture decision, or decision record.

Implement phase of RPI methodology. Executes a task-graph-driven implementation using isolated agents with strict RED/GREEN/VALIDATE gate enforcement. Use when executing an implementation plan from the draft skill.

Creates architecture diagrams using LikeC4 (structural C4, dynamic flows) or Mermaid (data flow diagrams). Use when creating C4 diagrams, architecture diagrams, sequence diagrams, data flow diagrams, or any system visualization.

Draft phase of RPI methodology. Consumes research artifact or topic and produces compact implementation plan with test specs and Agent Context blocks. Activates naturally inside plan mode for non-trivial work, or invoke explicitly with /draft. Use after research or to start planning a non-trivial feature.

Architectural guidance for hexagonal (ports and adapters) patterns. Does not generate files — use scaffold for project generation. Use when designing application structure, separating domain from infrastructure, creating testable boundaries, or when user mentions ports, adapters, hexagonal, or clean architecture.
