usage

# /usage — Cost Summary Show usage costs in the OpenClaw-compatible format. Works from CLI or messaging channels. ## Output format (matches OpenClaw exactly) ``` 💸 Usage cost Session <cost> · <tokens> tokens Today <cost> Last 30d <cost> ``` ## Subcommands - `/usage` — show the cost summary (default) - `/usage tokens` — compact token display - `/usage full` — verbose token + cost - `/usage cost` — same as default ## Steps 1. **Detect surface** (CLI vs messaging channel). 2. **Try to read session cost data** from Claude Code's session store: ```bash ls ~/.claude/projects/*/\*.jsonl 2>/dev/null | head -3 ``` NOTE: Claude Code stores session data in `~/.claude/projects/<slug>/*.jsonl`. The plugin cannot reliably read these because: - The session slug depends on the current cwd - The format is internal to Claude Code - Token counts per session are not always available to skills 3. **Fall back to estimate from memory/dreams**: - Call `agent_status` MCP tool → get file/chunk counts - Bash: `du -sh memory/ | awk '{print $1}'` → memory dir size - Bash: `wc -l memory/.dreams/events.jsonl 2>/dev/null | awk '{print $1}'` → event count 4. **Build the response** in OpenClaw format: ### When cost data is available ``` 💸 Usage cost Session $0.42 · 125k tokens Today $1.23 Last 30d $34.56 ``` ### When cost data is NOT available (most likely case) ``` 💸 Usage cost Session n/a (run native /cost or /usage in CLI for tokens) Today n/a Last 30d n/a ...
