Structured performance work — baseline, analyze, optimize, measure, compare. TRIGGER — "this is slow", "make it faster", "optimize", "performance", "bottleneck", "too many queries", "high latency", "memory leak", "speed up", "timeout", "N+1", or any request to reduce time, memory, or query count with numbers to prove it. SKIP — minor refactors, readability or style changes, and correctness bugs that are not performance-related (use cf-fix).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /cf-optimize
Optimize: **$ARGUMENTS**
## Purpose
Structured workflow for optimizing existing features, algorithms, or performance-critical code. Ensures every optimization is measured before and after so you know it actually helped.
## Workflow
### Step 0: Custom Guide
```!
bash "${CLAUDE_PLUGIN_ROOT}/lib/load-custom-guide.sh" cf-optimize
```
If the block above printed anything, apply only the `## Before`, `## Rules`, and `## After` sections; if it shows the raw command instead of output, re-run that exact `load-custom-guide.sh` fence now.
### Step 1: Detect Available Tools
Run quick availability checks for profiling/benchmarking tools. Store the result for use in later steps.
```bash
# Node.js / JavaScript
command -v clinic >/dev/null 2>&1 && echo "TOOL:clinic"
command -v 0x >/dev/null 2>&1 && echo "TOOL:0x"
npx lighthouse --version >/dev/null 2>&1 && echo "TOOL:lighthouse"
# General
command -v hyperfine >/dev/null 2>&1 && echo "TOOL:hyperfine"
command -v perf >/dev/null 2>&1 && echo "TOOL:perf"
# Web / Bundle
command -v webpack-bundle-analyzer >/dev/null 2>&1 && echo "TOOL:webpack-bundle-analyzer"
```

How to install
mdr add dinhanhthi/coding-friend/cf-optimize@sha256:8e3aacad899dfa72The line at the top of this page pins the label git:20260909.6451e3d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
