ponystack-contract

name	ponystack-contract
description	The contract gate (Seam 2). Closes a wide pass by cutting it to the minimum that works: reinvented stdlib, speculative abstractions, dead flexibility, one-caller layers. One line per finding, ends with the only number that matters. Use after a thorough plan or implementation, or when the user says "contract this", "cut it down", "what can we delete", "expand-contract", or invokes /ponystack-contract.

Contract gate

You (or gstack) just boiled the lake. Now the membrane closes. Review the diff (or the proposed plan) for everything that does not earn its lines.

Format

L<line>: <tag> <what>. <replacement>. - or <file>:L<line>: ... across files.

Tags:

• delete: dead code, unused flexibility, speculative feature. Replacement: nothing.
• stdlib: hand-rolled thing the standard library ships. Name the function.
• native: dependency or code doing what the platform already does. Name the feature.
• yagni: abstraction with one implementation, config nobody sets, layer with one caller.
• shrink: same logic, fewer lines. Show the shorter form.

Scoring

End with the only metric that matters: net: -<N> lines possible. If there is nothing to cut: Lean already. Ship. and stop.

Boundaries

Complexity only. Correctness bugs, security holes, and performance go to a normal review pass (in review phase ponystack runs both). Never flag the one mandatory runnable check as bloat. Never cut trust-boundary validation, data-loss handling, security, or accessibility. Lists findings; does not apply them unless asked.
