Feature to Plan

$ARGUMENTS

Planning Steps

1. Read the protocol spec

Load .claude/skills/inertia-protocol/SKILL.md and identify which protocol behaviors are involved.

2. Check the Laravel reference implementation

Read /home/tony/Documents/tony/inertia-laravel to see how the same feature is handled in the Laravel bundle. Use it as a reference for expected behavior and conventions.

3. Read existing code

Explore relevant files in src/ to understand the current state.

4. Write the plan

The plan must include:

Files to create (with their purpose):

src/NewClass.php       — Description of responsibility
tests/Unit/...         — Unit tests for NewClass
tests/Functional/...   — Protocol compliance tests

Files to modify (with what changes):

src/ExistingClass.php  — Add method X, modify method Y
config/services.yaml   — Register new service
config/definition.php  — Add new config option if needed

Implementation order (TDD sequence):

1. Write test for behavior A → implement A
2. Write test for behavior B → implement B
3. ...

Protocol compliance checklist:

• Which protocol behaviors are covered?
• Which edge cases need tests?

Risks / open questions:

• Any ambiguity in the spec?
• Symfony version compatibility concerns?

5. Present the plan for review

Do NOT start implementing. Present the plan and wait for approval. If the plan is approved, use /tdd to implement step by step.
