Ln 629 Lifecycle Auditor

levnikolaevich/claude-code-skills
313 installs533 stars
Summary

This is an L3 worker that audits your application's lifecycle management, checking bootstrap sequences, shutdown handlers, signal handling, and health probes. It reads from a core contract spec and calculates a compliance score out of 10 for medium priority lifecycle concerns. You'd reach for this when you need a structured assessment of how your app starts up, shuts down, and responds to system signals. It's part of a larger audit framework (note the ln-* sibling references), so it assumes you're working within that ecosystem. The compliance scoring is nice for tracking improvements over time, though the real value is in catching missing graceful shutdown logic before it bites you in production.

improve

shadcn/improve

Survey any codebase as a senior advisor and produce prioritized, self-contained implementation plans for OTHER models/agents to execute. Strictly read-only on source code — never implements, fixes, or refactors anything itself. Use when asked to audit a codebase, find improvement opportunities (bugs, security, performance, test coverage, tech debt, migrations, DX), suggest features or where to take the project next (roadmap, product direction), or generate handoff plans for another agent to implement.
