What it does

The repository, listed here as sol-simplify, now carries the name frontier-simplify. Its core is a single Markdown skill file for coding agents such as Claude Code and Codex. It targets the habit of agents building their own gates, registries, validators and checklists, and asks the agent to keep only process that serves a real obligation, marking anything it keeps with a removal condition. Two further skills are described. One audits an existing repository for this kind of overhead and only reports, changing no files. The other is an optional review runner that preserves review findings, checks repairs against them and limits automatic attempts to three per pull request. The runner needs Bash, Git and Python 3.9 or later, plus Codex or Claude Code for live reviews. Installation is through the Codex or Claude Code plugin marketplaces, or by copying the file into a skills or rules folder. The author's benchmark figures are tied to specific model runs, and the page says effectiveness has to be measured per model.
