How It Works

A disciplined workflow from planning to knowledge capture.

Plan

Brainstorm your approach. Coding Friend explores the codebase, identifies patterns, and writes a structured plan.

terminal

$ /cf-plan Build a REST API with auth

Creating implementation plan...

Exploring codebase...
Identifying patterns...
Designing approach...

Plan written to docs/plans/rest-api-auth.md

Implement

Write code with TDD enforced. Every feature starts with a failing test, then implementation, then refactor.

terminal

$ Write the auth middleware

cf-tdd activated

RED: Writing failing test...
  auth.test.ts: should reject invalid tokens

GREEN: Implementing...
  auth.middleware.ts: JWT validation

REFACTOR: Cleaning up...
  All tests passing (3/3)

Review

Multi-layer code review runs in a separate subagent. Checks security, performance, style, and test coverage.

terminal

$ /cf-review src/auth/

Code Review (forked subagent)

Security: No injection vulnerabilities
Performance: Token caching recommended
Style: Consistent with codebase
Tests: 100% branch coverage

2 suggestions, 0 issues

Ship

One command to verify, commit, push, and create a pull request. Smart conventional commits included.

terminal

$ /cf-ship Add JWT auth middleware

Verification: All tests passing (12/12)
Commit: feat(auth): add JWT middleware
Push: origin/feat/jwt-auth
PR: #42 created

https://github.com/.../pull/42

Learn

Capture what you learned from the session. Generate docs, host as a website, or integrate with other LLM clients.

terminal

$ /cf-learn

Extracting knowledge...

JWT Authentication Patterns
  Token validation flow
  Middleware composition
  Error handling strategies

Saved to docs/learn/Web_Dev/jwt-auth.md
Host with: cf host

Smart Statusline

Always know what's happening. Your terminal statusline, upgraded with real-time project context.
