Implement a feature following TDD workflow. $ARGUMENTS is a spec file path (e.g., `specs/my-feature.md`) or a plain-text feature description. **Scope**: This skill writes Go code and tests. It does NOT update website docs (use `update-docs` after) or CHANGELOG (use `changelog` after). ## Workflow ### Step 1: Understand Requirements If $ARGUMENTS is a file path: 1. Read the spec file 2. Extract acceptance criteria and edge cases 3. Identify affected packages If $ARGUMENTS is a description: 1. Search existing code for related functionality 2. Identify the right package to extend 3. Confirm scope with user before proceeding ### Step 2: Identify Affected Files List all files that will be created or modified: ```bash # Typical pattern for a new command cmd/skillshare/<command>.go # Command handler cmd/skillshare/<command>_project.go # Project-mode handler (if dual-mode) internal/<package>/<feature>.go # Core logic tests/integration/<command>_test.go # Integration test ``` Display the file list and continue. If scope is unclear, ask the user. ### Step 3: Write Failing Tests First (RED) Write integration tests using `testutil.Sandbox`: ```go func TestFeature_BasicCase(t *testing.T) { sb := testutil.NewSandbox(t) defer sb.Cleanup() // Setup sb.CreateSkill("test-skill", map[string]string{ "SKILL.md": "---\nname: test-skill\n---\n# Content", }) // Act result := sb.RunCLI("command", "args...") // Assert result.As...
