perf-tuning

97 / 100 · Low risk

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

By vamseeachanta/workspace-hub (GitHub) · coding · 20 stars · scanned at commit 188b078

Diagnose local machine slowness and apply CPU/IO/governor tuning. Use when work feels slow on ace-linux-1 / ace-linux-2 — Hermes lagging, git operations taking minutes, builds dragging, Claude Code feeling sluggish. Runs perf-bench.sh, identifies the dominant bottleneck (CPU governor, filesystem driver, NUMA, memory pressure, I/O contention), and applies fixes from the perf-tuning runbook.

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/'perf-tuning' ] || [ -L ~/.agents/skills/'perf-tuning' ]; then echo 'A skill folder named perf-tuning already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/vamseeachanta/workspace-hub' "$d" && git -C "$d" checkout --quiet '188b0785ec3a3723c741c69f0b4f9d34fa113aaa' -- '.agents/skills/operations/devops/perf-tuning' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/operations/devops/perf-tuning' ~/.agents/skills/'perf-tuning' && 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/'perf-tuning' ~/.claude/skills/'perf-tuning' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
