From d65bc701dafbe985152a915627c69981aa6d5c19 Mon Sep 17 00:00:00 2001 From: tegwick Date: Sun, 29 Mar 2026 17:46:46 +0200 Subject: [PATCH] feat(token-tracking): record AI token consumption per task (CUST-WP-0029) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduces end-to-end token consumption tracking so agent work is visible as a cost/effort metric alongside tasks and workplans. - Migration o2j3k4l5m6n7: token_events table with FK indexes on task_id, workstream_id, repo_id, created_at - ORM model, Pydantic schemas (TokenEventCreate, TokenEventRead with computed tokens_total, TokenSummary) - Router: POST /token-events/, GET /token-events/ (7 filters), GET /token-events/summary/ (task|workstream|repo|commit|release scope) - MCP tools: record_token_event, get_token_summary (formatted table) - update_task_status enriched with optional tokens_in/tokens_out passthrough — one call creates status update + token event - Dashboard token-cost.md page: by-repo bar, by-workplan table, by-model bar, top-10 tasks by tokens - ralph-workplan skill updated with token reporting guidance and per-task heuristics for estimating counts - Tests: test_token_events.py + test_token_passthrough.py (182 pass) Co-Authored-By: Claude Sonnet 4.6 --- state-hub/api/main.py | 2 + state-hub/api/models/__init__.py | 2 +
