usage-snaplisted

# usage:snap Show how much the current (or specified) task has consumed so far. ## Trigger - "usage snap" - "usage check" - "얼마나 썼나" - "토큰 사용량" ## Parameters - **taskId** (optional): Specific task ID. If omitted, shows all active tasks. ## Procedure ### 1. Load tasks ```bash cat "$HOME/.claude/usage-tracker/tasks.json" ``` Filter to active tasks (status = "active"). If taskId specified, filter to that one. ### 2. Query ccusage for each task's sessions For each task, get session data: ```bash ccusage session --since {task.startedAt as YYYYMMDD} --json --breakdown ``` Parse the JSON output. Match sessions by sessionId from the task's sessions array. **Matching logic:** - ccusage sessions have `sessionId` field (project path based, e.g., `-Users-nhn-git-project-aetherion-spec-guide`) - Task sessions have `id` field (UUID, e.g., `ebedca79-...`) - Match: task session `id` should appear as a JSONL filename under the ccusage session's project path - For simplicity: aggregate ALL ccusage sessions whose `sessionId` matches any of the task's binding projects ### 3. Calculate metrics For each task: - **Total tokens**: sum of totalTokens across matched sessions - **Total cost**: sum of totalCost - **Input/Output/Cache breakdown** - **Session count**: number of sessions - **Duration**: startedAt to now - **Cost per day**: totalCost / days active ### 4.
