skillshare-implement-feature

1Implement a feature following TDD workflow. $ARGUMENTS is a spec file path (e.g., `specs/my-feature.md`) or a plain-text feature description.

3**Scope**: This skill writes Go code and tests. It does NOT update website docs (use `update-docs` after) or CHANGELOG (use `changelog` after).
4 
5Before acting, run `python3 scripts/ai-context.py cli-development testing`. Those topics are the source of truth for repository patterns, execution boundaries and verification; this skill retains the TDD orchestration.

7## Workflow
8 
9### Step 1: Understand Requirements
10 
11If $ARGUMENTS is a file path:
121. Read the spec file
132. Extract acceptance criteria and edge cases
143. Identify affected packages
15 
16If $ARGUMENTS is a description:
171. Search existing code for related functionality
182. Identify the right package to extend
193. Ask the user only if ambiguity would materially change scope or public interfaces
20 
21### Step 2: Identify Affected Files
22 
23List all files that will be created or modified:
24 
25```bash
26# Typical pattern for a new command
27cmd/skillshare/<command>.go          # Command handler
28cmd/skillshare/<command>_project.go  # Project-mode handler (if dual-mode)
29internal/<package>/<feature>.go      # Core logic
30tests/integration/<command>_test.go  # Integration test
31```
32 
33Display the file list and continue.
34 
35### Step 3: Write Failing Tests First (RED)
36 
37Write integration tests using `testutil.Sandbox`:
38 
39```go
40func TestFeature_BasicCase(t *testing.T) {
41    sb := testutil.NewSandbox(t)
