This skill should be used when creating plan files, writing Gherkin requirements, or parsing plan file structure. Provides the plan file template and format specifications.

Specification for plan files used by the tommymorgan plugin. Plan files capture feature requirements as Gherkin scenarios with TODO/DONE tracking.
Specification for plan files used by the tommymorgan plugin. Plan files capture feature requirements as Gherkin scenarios with TODO/DONE tracking.
Plan files serve as the single source of truth for feature development:
<!-- TODO --> / <!-- DONE --> comment markersPlan files live in the project's plans directory:
<project>/plans/YYYY-MM-DD-<slug>.md
Where:
<project> is the project path (e.g., apps/web, libs/shared, tools/cli)YYYY-MM-DD is the creation date<slug> is a kebab-case version of the feature nameExample: apps/web/plans/2025-12-15-user-authentication.md
# Feature: <Title>

## User Requirements

Required fields:
**Created**: Date in YYYY-MM-DD format**Goal**: Single sentence describing user-facing outcomeLanguage/framework agnostic Gherkin scenarios describing user-facing behavior.
Rules:
Implementation-specific Gherkin scenarios with actual technology versions.
Rules:
Each scenario has metadata comments:
# Living: <project>/features/<file>.feature::<scenario-name>
# Action: creates|replaces|extends|removes|deprecates
# Status: TODO
# Living updated: NO
Living: Path to the corresponding living specification file, or none (initial implementation) for new features.
Action: Relationship to existing living specs:
creates — New, independent scenarioreplaces — Completely replaces an existing scenarioextends — Adds to an existing scenarioremoves — Deletes an existing scenario from the living specdeprecates — Marks an old scenario as obsoleteStatus: TODO or DONE — matches the <!-- TODO --> / <!-- DONE --> HTML comment marker.
Living updated: NO, YES, or N/A — whether the living spec file has been updated.
Markdown checklist of documentation files affected by the planned changes. Appears after Technical Specifications and before Notes.
## Affected Documentation
- [ ] Update README.md — describe new feature in usage section
- [ ] Update CLAUDE.md — document new commands

## Affected Documentation
No existing documentation is affected by these changes.
Preserve context for future sessions:
Progress is tracked via HTML comment markers above each scenario:
<!-- TODO --> — Scenario not yet implemented<!-- DONE --> — Scenario implemented and verifiedThe status and work commands parse these markers to determine progress.

Plan file validation:
# Feature:<!-- TODO --> or <!-- DONE --> markernpx claudepluginhub tommymorgan/claude-plugins --plugin tommymorganGenerates a TDD-driven implementation plan from a finalized brainstorm-beagle spec. Turns .beagle/concepts/<slug>/spec.md into actionable 2-5 minute tasks with exact file paths and commands, saved to plan.md after user approval.
Generates TDD-ready task specs from feature plans via developer collaboration, drafting test plans and embedding specs into the plan document before coding.
Creates detailed implementation plans from specs for multi-step tasks before coding, with file structure mapping, bite-sized TDD steps, architecture overview, and tech stack.
