e2e-driven-iteration

100 / 100 · Low risk

Fine to try.

By CorvinLabs/CorvinOS (GitHub) · coding · 25 stars · scanned at commit 3f28cfd

Use at the start of every inner-loop iteration where the goal is to fix a bug / close a failing test / reach a green E2E. Forbids editing code without first running the E2E to capture a fresh loss signal, and forbids declaring "done" without the E2E passing. Makes the cycle "E2E → loss → 5-why-by-layer → fix → E2E" the only admissible rhythm.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'e2e-driven-iteration' ] || [ -L ~/.agents/skills/'e2e-driven-iteration' ]; then echo 'A skill folder named e2e-driven-iteration already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/CorvinLabs/CorvinOS' "$d" && git -C "$d" checkout --quiet '3f28cfd9b82326ff325e645ff041589c3220d813' -- 'corvin_operator/bundle/skills/ldd/e2e-driven-iteration' && mkdir -p ~/.agents/skills && cp -R "$d"/'corvin_operator/bundle/skills/ldd/e2e-driven-iteration' ~/.agents/skills/'e2e-driven-iteration' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'e2e-driven-iteration' ~/.claude/skills/'e2e-driven-iteration' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
