About this skill
The Senior Staff Coding Gatekeeper & Blast-Radius Engine is a development gatekeeper that constrains AI coding agents (Claude Code, Cursor, Codex, Windsurf, Aider) to disciplined, surgical, and minimal changes.
It halts common agent failure modes: hallucinated refactoring, speculative abstractions, unneeded third-party dependencies, out-of-scope file modifications, and untested code merges.
Key Capabilities:
- The 7-Rung Senior Dev Ladder: Enforces YAGNI, existing helper reuse, standard library priority, and native platform features before writing new code.
- Blast-Radius & Diff Budget Enforcer: Strict line and file limits (bug fixes ≤30 lines, ≤2 files) to prevent agent scope creep.
- Root Cause Analyzer: Greps all callers of modified functions to fix bugs at the root with a single shared guard.
- Zero-Bloat Verification Proof: Leaves behind a single standalone assert test to verify changes without test framework bloat.
Does not replace human architectural review for multi-team organizational rewrites. Focuses on enforcing surgical diff boundaries and engineering discipline on individual coding tasks.
