SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Turning an approved technical plan into working code requires disciplined execution: reading the full plan, tracking progress across phases, verifying each step, and handling mismatches between the plan and the actual codebase. This Skill operationalizes that process so plans stored in thoughts/shared/plans are implemented completely and consistently. ## Core Features & Use Cases - Plan-Driven Implementation: Reads a plan file from thoughts/shared/plans, checks existing checkmarks, and implements each phase in order. - Verification Loop: Runs the plan's success criteria (such as make check test) after each phase and checks off completed items directly in the plan file. - Mismatch Handling: Stops and presents a structured issue report (expected vs. found) when reality diverges from the plan, and supports resuming from the first unchecked item. - Use Case: After a planning stage produces thoughts/shared/plans/add-auth.md, invoke this Skill to implement all phases consecutively, updating checkboxes as work completes. ## Quick Start Ask the agent to run ff_implement_plan on the plan file at thoughts/shared/plans/your-plan.md and implement all remaining phases.

FAQPage Schema
How do I implement a technical plan with an AI coding agent?▼

Provide the path to a plan file in thoughts/shared/plans and invoke the ff_implement_plan command. The agent reads the full plan and referenced files, implements each phase in order, runs the success criteria checks, and checks off completed items in the plan.

How do I resume a partially completed implementation plan?▼

Re-run the command with the same plan path. The agent trusts existing checkmarks, picks up from the first unchecked item, and only re-verifies earlier work if something appears inconsistent.

What happens when the codebase does not match the plan?▼

The agent stops and presents a structured mismatch report showing the phase, what the plan expected, what was actually found, and why it matters, then asks how to proceed rather than guessing.

Does the implementation skill run tests automatically?▼

Yes. After each phase it runs the plan's success criteria, typically covered by make check test, fixes any failures, and only then moves to the next phase without pausing for confirmation.

When should I not use plan-based implementation?▼

Avoid it when no approved plan exists yet, since the command requires a plan path, or when changes are trivial enough that writing a phased plan adds unnecessary overhead.
