verify

92 / 100 · Low risk

Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Verify that a code change actually does what it's supposed to by exercising it end-to-end and observing behavior — drive the affected flow, not just tests or typecheck. Run before committing nontrivial changes; bootstraps this repo's project verify skill if none exists yet. Don't invoke it on a diff that only touches tests, docs, or other code with no runtime surface to drive (a change to product source always has one) — there's nothing to observe.

Works with any agent that supports SKILL.md skills.

Install

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

if [ -e ~/.agents/skills/'verify' ] || [ -L ~/.agents/skills/'verify' ]; then echo 'A skill folder named verify already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/asgeirtj/system_prompts_leaks' "$d" && git -C "$d" checkout --quiet '2209631d6d3da737c22159ed03c5127734b187f3' -- 'Anthropic/claude-code/skills/verify' && mkdir -p ~/.agents/skills && cp -R "$d"/'Anthropic/claude-code/skills/verify' ~/.agents/skills/'verify' && 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/'verify' ~/.claude/skills/'verify' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
