+# TODO
+
+## Custom game prompt
+
+- Keep the default prompt (`prompt.txt`) as the base for every game.
+- Add an optional **per-game custom prompt** in the UI that merges with the default (custom rules layered on top of shared instructions, not a full replacement unless explicitly chosen).
+- Surface this in settings / project setup so each game folder can carry its own tone, terminology notes, or content warnings without forking the global prompt.
+
+## Batch history tab
+
+- Add a **Batch** tab (or dedicated panel) in the GUI to manage past Anthropic batch runs saved locally.
+- Persist batch metadata locally (batch id, submit time, file set, status, cost estimate, etc.) alongside existing `log/batch_*.json` artifacts (`batch_state.json`, `batch_results.json`, `batch_requests.json`).
+- Actions:
+  - **List batches** — browse all batches the tool has submitted or tracked for this project.
+  - **Redownload** — fetch results again from Anthropic for a completed batch (e.g. after a crash before consume, or to recover results). **Not in sketch yet.**
+  - **Cancel batch** — cancel an in-flight batch where the API allows it (`in_progress` → `canceling` → `ended`).
+  - **Usage / cost** — sum real billed tokens from batch results (input, output, cache read/write, thinking).
+  - Resume / link into the existing collect → submit → consume flow when a batch is still pending or fetched but not consumed.
+
+### Sketch: CLI batch manager (adapt for DazedMTLTool)
+
+Reference from sibling tooling (`batches.py`). Port to this repo using `_get_anthropic_client()` / `fetchTranslationBatches()` in `util/translation.py` and `log/batch_state.json` (maps to sketch's `tl/_batch_state.json`).
+
+```python
+#!/usr/bin/env python3
+# -*- coding: utf-8 -*-
+"""
+batches.py — list and cancel Anthropic Message Batches (the ones DazedMTLTool
+submits). Handy when a run is stuck polling or you submitted by mistake.
+
+    set ANTHROPIC_API_KEY=sk-...   # or key= in .env
+
+    python tooling/batches.py                 # list recent batches (default)
+    python tooling/batches.py list --limit 50
+    python tooling/batches.py cancel <batch_id> [<batch_id> ...]
+    python tooling/batches.py cancel --all     # cancel every in-progress batch
+    python tooling/batches.py cancel --mine    # cancel batch(es) in log/batch_state.json
+    python tooling/batches.py usage [batch_id] # real billed tokens + estimated cost
+
+    # TODO: redownload <batch_id>  — re-fetch results into log/batch_results.json
+
+Only an in-progress batch can be cancelled; cancellation finishes any in-flight
+requests (in_progress -> canceling -> ended). Already-ended batches can't be
+cancelled.
