Fine to try.

How a contest program spends its time limit: input and output, the margin, exact operation counts, compiler pragmas, light random numbers, no allocation in loops, caching and memoisation, the precompute step, and the time-limit ladder. Use when writing or speeding up the solution, and whenever a run exceeds the time limit.

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/'cpp-performance' ] || [ -L ~/.agents/skills/'cpp-performance' ]; then echo 'A skill folder named cpp-performance already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/Leeroo-AI/kapso' "$d" && git -C "$d" checkout --quiet '35f7b9b26a6b3864fdc8c018577d448c2840345b' -- 'src/kapso/harness/bundled/competitive-programming/skills/cpp-performance' && mkdir -p ~/.agents/skills && cp -R "$d"/'src/kapso/harness/bundled/competitive-programming/skills/cpp-performance' ~/.agents/skills/'cpp-performance' && 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/'cpp-performance' ~/.claude/skills/'cpp-performance' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
