A PRD Builder Slash Command for Claude Code (TDD + Spec-Driven + Recursive Testing)

@agentic.jamesCapturedClaude Code / Skills

Exact instruction

Create a custom slash command in Claude Code (.claude/commands/) that takes a project name as an $ARGUMENTS variable.
Have the command generate a PRD that doubles as agent instructions: define test suite + success criteria first, then implementation.
Instruct the agent to run tests and git commit after every significant feature.
Instruct the agent to re-test prior features after each new feature lands (regression check).
Reserve a section in the PRD for the agent to leave itself notes for future sessions.

Suggested prompt

Before implementing any feature, first design the test suite and success criteria for it. After implementing, run unit/integration tests, commit if they pass, then re-run tests for previously implemented features to catch regressions. Leave a 'Notes to future self' section at the bottom of this doc and update it as you go.

Adopt?

Yes: This is a more rigorous version of spec-driven development applicable to Claude Code. Worth building a custom slash command that bakes in test-first + commit-after-each-feature + regression re-testing discipline, similar to what's described here.
