simplify-and-harden
Post-completion self-review for coding agents that runs simplify, harden, re-verification, and micro-documentation passes on non-trivial code or high-impact configuration changes. Use when a task is complete in a general agent session and you want a bounded quality and security sweep before signaling done. For CI pipeline execution, use simplify-and-harden-ci.

What this skill does
Agent Skill: Simplify & Harden Install For CI-only execution, use: Fallback using the Agent Skills CLI: Metadata Field Value --------------- -------------------------------- Skill ID simplify-and-harden Version 0.1.0 Trigger Post-completion hook Author Peter Skøtt Pedersen Category Code Quality / Security Priority Recommended Rationale and Philosophy When a coding agent completes a task, it holds peak contextual understanding of the problem, the solution, and the tradeoffs it made along the way. This context degrades immediately -- the next task wipes the slate. Simplify & Harden exploits that peak context window to perform two focused review passes before the agent moves on. Most agents solve the ticket and stop. This skill turns "done" into "done well." The operating philosophy is a deliberate "fresh eyes" self-review before moving on: carefully re-read all newly written code and all existing code modified in the task, and look hard for obvious bugs, errors, confusing logic, brittle assumptions, naming issues, and missed hardening opportunities. The goal is not to expand scope or rewrite the solution -- it is to use peak context to perform a disciplined first review pass while the agent still remembers the intent behind every change. Best Use with Independent Review This skill is a post-completion self-pass and does not replace an independent review pass. Recommended flow: 1. Implement the task. 2. Run Simplify & Harden to clean, harden, and document non-obvious decisions. 3. Run an independent review pass for severity-ordered findings. 4. Merge only after both passes are addressed. If the two disagree, treat the independent review findings as the external gate and either fix or explicitly waive findings. …
