The */5 in the cron example inside the JSDoc block comment was parsed as end-of-comment, causing a SyntaxError. Replaced with a reference to install.sh. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

/**
|
|
* Claude Usage Fetcher (Standalone)
|
|
*
|
|
* Fetches token usage from claude.ai API using a session key.
|
|
* Designed to run as a cron job on headless servers.
|
|
*
|
|
* Session key source (checked in order):
|
|
* 1. CLAUDE_SESSION_KEY env var
|
|
* 2. ~/.config/claude-statusline/session-key (plain text file)
|
|
*
|
|
* To get your session key:
|
|
* 1. Log into claude.ai in any browser
|
|
* 2. Open DevTools → Application → Cookies → claude.ai
|
|
* 3. Copy the value of the "sessionKey" cookie
|
|
* 4. Save it: echo "sk-ant-..." > ~/.config/claude-statusline/session-key
|
|
*
|
|
* Output: Writes JSON to $CLAUDE_USAGE_CACHE or /tmp/claude_usage.json
|
|
*
|
|
* Cron: every 5 min (see install.sh or README for crontab line)
