What problem does it solve? Debugging without context often leads to fixes that violate intended behavior. This Skill grounds bug fixes in the feature specification, ensuring code changes match what the spec says the code should do. ## Core Features & Use Cases - Spec-Aware Bug Mapping: Loads spec.md, tasks.md, and constitution.md to map a natural-language bug description to the relevant user story, functional requirement, or acceptance criterion. - Plan-Then-Act Workflow: Presents a proposed fix plan with root cause analysis and waits for explicit user approval before modifying any code. - Guardrails and Escalation: Warns on scope creep (more than 4 files), flags spec conflicts, and hard-blocks fixes that violate constitution principles. - Use Case: A user reports "login link email never arrives in dev mode." The Skill maps the bug to the authentication user story in spec.md, locates the email backend code referenced in completed tasks, proposes a minimal fix, and applies it after approval. ## Quick Start Run /speckit.fixit.run followed by a natural-language description of the bug you want fixed, such as "/speckit.fixit.run the plant list returns duplicates after filtering".
