# HERO — Anti-OverDefense

A short block of text pasted into a coding agent's configuration file that names four shapes of unnecessary defensive behavior, hashing, edge-case handling, rubric-chasing and overbuilding, so a developer can call out which one just happened instead of arguing about vibes.

HERO stands for Hashing, Edge cases, Rubrics and Overbuild, four repeated patterns the project's author observed in coding-agent responses where an agent builds elaborate safeguards around a feature instead of finishing the feature itself. Rather than a tool to install, HERO is a short contract, provided in English and Chinese, meant to be pasted into an agent's own configuration file, alongside per-host notes for where to paste it in Claude Code, Codex, Antigravity, Cursor, GitHub Copilot, Windsurf and Gemini CLI.

A cases folder documents specific observed instances, what was asked, what the agent did, and why it was disproportionate, meant to be quoted back at an agent that argues its own behavior was reasonable rather than pasted into its configuration. An examples folder collects unrelated AGENTS.md and CLAUDE.md files that other contributors adapted for their own projects, shared to show the approach rather than as ready-made HERO variants.
