CCO Doctor

When the user runs /cco-doctor or reports the plugin "isn't working", run a quick health check.

How to use

Standard run (fast — under 1s):

node ${CLAUDE_PLUGIN_ROOT}/src/doctor.js

With test suite (slower — runs all unit tests):

node ${CLAUDE_PLUGIN_ROOT}/src/doctor.js --tests

What it checks

• Plugin manifest and package.json exist
• Versions are in sync (plugin.json and package.json)
• hooks.json is valid JSON with all expected event types
• All hook scripts present in src/
• Data directory ~/.claude-context-optimizer/ is writable
• patterns.json size is reasonable
• Global stats file is parseable
• User config has sane model + budget for the chosen model
• Node version meets the >=18 requirement

Presentation

Translate the doctor output into plain language. If anything is fail, walk the user through the fix:

• versions out of sync → npm run sync-version
• patterns.json too big → /cco-clean
• budget > model window → /cco-budget set <smaller> or pick a 1M-context model (e.g. opus-4.8)
• node too old → upgrade Node

If everything is pass, confirm "плагин в порядке, текущая версия Х.Y.Z" and stop.
