Feature RPI

Use this skill for medium and large changes.

Start

Open these first:

• README.md
• docs/TECH_STACK.md
• docs/RPI_METHODOLOGY.md
• AGENTS.md
• one or more of:
  • docs/AGENT_ARCHITECTURE.md
  • docs/ANTI_HALLUCINATION_SOP.md
  • docs/PHASE_REGISTRY.md
  • docs/algorithms.md

Research

• identify the real execution path before editing
• inspect affected interfaces, neighboring modules, and verification points
• capture file paths, constraints, and open risks
• keep reading focused; do not preload unrelated subsystems

Plan

• produce a short numbered plan before editing
• name touched files or areas
• define acceptance criteria and verification commands
• run the gap-check skill if the change affects architecture, scoring, safety, or orchestration

Implement

• make the smallest coherent multi-file change set
• preserve separation of concerns from AGENTS.md
• keep files under the 200-line guideline
• verify iteratively instead of waiting until the end

Verification

• run focused tests or lint/typecheck commands for the touched surface
• if full verification is not possible, state what was or was not run

Stop And Rescope When

• the task crosses into an unexpected subsystem
• the plan assumptions no longer hold
• context is approaching the dumb zone
