WOZCODE Savings Benchmark

Runs a head-to-head benchmark of WOZCODE vs vanilla Claude Code on your own repo and reports cost, turn, and time savings.

Dev & CodingIntermediate★ 209⑂ 25AI score 8/10Last updated: Aug 17, 2026

What it does

  • Fires on phrases like "compare woz", "benchmark woz", "woz vs claude", "how much does woz save", or the /woz-benchmark command.
  • Validates the target first: directory exists, is a git repo, and has a clean working tree — otherwise it stops with fix instructions.
  • Collects 2–10 real coding tasks (plus optional environment setup commands) in a single short prompt and writes a temporary YAML config to /tmp/woz-benchmark-<timestamp>.yaml, defaulting to the opus model.
  • Executes benchmark.js with --user-env so each prompt runs twice (WOZCODE and vanilla), with git reset --hard restoring the repo between runs.
  • Relays the full report and prepends a savings summary computed from the totals.

Who it's for

  • Existing WOZCODE plugin users who are logged in.
  • Teams that need hard numbers (cost, turns, wall time) to justify a tool decision.
  • Developers who want agent performance measured on their actual codebase rather than synthetic tasks.

Example uses

  1. "how much does woz save?" → hand it a repo path and three refactor/bugfix tasks, get a comparison report.
  2. Run /woz-benchmark and include DB seed commands so data-dependent projects are benchmarked fairly.
  3. Point it at a repo with uncommitted work — it halts immediately and tells you to commit or stash first.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/WithWoz/wozcode-plugin/HEAD/codex/wozcode/skills/woz-benchmark/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the codex/wozcode/skills/woz-benchmark folder from the GitHub repo WithWoz/wozcode-plugin into my ~/.claude/skills/woz-benchmark/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/WithWoz/wozcode-plugin.git && mkdir -p ~/.claude/skills && cp -r wozcode-plugin/codex/wozcode/skills/woz-benchmark ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/WithWoz/wozcode-plugin.git
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy the skill: cp -r wozcode-plugin/codex/wozcode/skills/woz-benchmark ~/.claude/skills/
  5. This skill depends on the WOZCODE plugin's benchmark.js. Install the plugin at ~/.codex/plugins/wozcode (or $CODEX_HOME/plugins/wozcode) per the repo README and log in to WOZCODE.
  6. Restart Claude Code, then type "benchmark woz" or /woz-benchmark.
  7. Make sure your benchmark target is a clean git repo — check with git status before starting, since runs use git reset --hard.
