Eco Audit

Audit this machine's Claude Code configuration for token waste - effort level, oversized CLAUDE.md files, MCP servers, tool-output caps, env keys that do nothing, startup skill load - and print the exact settings.json edit that fixes each finding. Read-only; it never writes settings. Use when the user asks why their usage or bill is high, or wants a config, context or startup-cost checkup, in any language.

Eco audit - read-only configuration audit

Run this once, from the user's project directory:

node "${CLAUDE_PLUGIN_ROOT}/scripts/audit.mjs" $ARGUMENTS

Then:

The script's table and settings diff are already on the user's screen as the command's output. Do not reprint them - repeating output the user can already see is exactly the waste this plugin exists to remove. Never re-summarise, re-sort or re-word the rows either: the numbers and the "est" labels are the product, and a paraphrase of them is a worse product.
Add at most 3 lines of your own: which finding to fix first, and why.
Never apply the diff here. Applying it is /eco setup, which shows the diff and waits for the user to confirm. Say so and stop.
If ${CLAUDE_PLUGIN_ROOT} did not expand (the path still contains that literal text), this is a personal or project install rather than a plugin: run audit.mjs from this skill's own directory - the installer stages it there - and if it is missing, scripts/audit.mjs in the claude-code-eco checkout.
