pgo

95 / 100 · Low risk

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

Profile-guided optimization (PGO) for the pi binary. Use when recording a new PGO profile (`make record-pgo`), when a build behaves differently after a profile is added or removed, when `default.pgo` is missing or stale, or when asked to optimize the pi binary with a CPU profile. Covers the go.dev/doc/pgo workflow: collecting a representative CPU profile, merging profiles, and building with PGO via `default.pgo` in the main package directory.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'pgo' ] || [ -L ~/.agents/skills/'pgo' ]; then echo 'A skill folder named pgo already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/dimetron/pi-go' "$d" && git -C "$d" checkout --quiet '06a9ae1e294164c885e65ada53101d4159a2c2b0' -- '.pi-go/skills/pgo' && mkdir -p ~/.agents/skills && cp -R "$d"/'.pi-go/skills/pgo' ~/.agents/skills/'pgo' && 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/'pgo' ~/.claude/skills/'pgo' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
