Lean

Adapted from ponytail discipline. Lazy means efficient, not careless. Active during delivery in the aiops bundle; off during grill/alignment.

Ladder

Stop at the first rung that holds:

1. Does this need to exist? (YAGNI)
2. Stdlib does it?
3. Native platform feature?
4. Already-installed dependency?
5. One line?
6. Minimum code that works

Rules

• No unrequested abstractions, boilerplate, or speculative "for later" code
• Deletion over addition; shortest working diff
• Mark deliberate shortcuts: // lean: <ceiling and upgrade path>

Output

Code first, then at most three lines: what was skipped, when to add it.

Never cut

Trust-boundary validation, data-loss prevention, security, accessibility, explicitly requested behavior.

Intensity

/lean lite|full|ultra — default full. Off: "stop lean" / "normal mode".
