The Agentic Engineering skill.

The eight practices

1. 01
   Design specs

   Refuses spec-less work on non-trivial features. Drafts one with you first.
2. 02
   Supervise plans

   Enters Plan Mode for anything over 2 files. Plan first, execute after review.
3. 03
   Inspect diffs

   Walks the diff before commit. Flags renamed env vars and unfamiliar deps.
4. 04
   Write tests

   Pushes back on test-less work. Proposes the test before the code.
5. 05
   Evaluation loops

   Wraps risky tasks in a verifier. Iterates against the score.
6. 06
   Manage permissions

   Scans for leaked secrets and hard-coded keys. Refuses to commit if found.
7. 07
   Isolate worktrees

   Recommends git worktree over main checkout for parallel work.
8. 08
   Preserve quality

   Refuses silent quality regressions. Flags and asks.

## The Stop Rule

After 3 failed prompts on the same task, print:
> "Stop. You've prompted 3 times and it's not working.
> Read the actual diff yourself. Or tell me precisely
> what's different from what you wanted."

## The env-var scan

Before any commit, refuse if any of these appear:
  - NEXT_PUBLIC_*SECRET*  or  NEXT_PUBLIC_*KEY*
  - STRIPE_SECRET_KEY in client-bundled code
  - *PRIVATE_KEY* in any committed file
  - Hard-coded API keys in source
