+# PPTX Translation
+
+Translate `.pptx` files between Chinese and English. Covers the full pipeline: extraction → translation → review → write-back.
+
+## Workflow
+
+### 1. Extract strings to YAML
+
+Run `scripts/extract.py original.pptx strings.yaml`. Produces YAML with entries:
+
+```yaml
+- slide: 1
+  shape: 0
+  run: 0
+  kind: title
+  zh: 开启生命的富足
+  en: ""
+```
+
+- `slide` — 1-based slide number
+- `shape` — 0-based shape index within slide
+- `run` — 0-based paragraph index within text frame (or computed index for tables)
+- `kind` — `title` | `subtitle` | `center_title` | `body` | `table` | `notes`
+- `zh` — source text
+- `en` — translation target (initially empty)
+
+Table `run` index formula: `num_rows * col + row`. Reverse with `row = run % num_rows`, `col = run // num_rows`.
+
+Speaker notes use `shape: -1`.
+
+### 2. Translate
+
+**Do NOT call external translation APIs.** Translate directly — the agent IS the model. The user corrects this: "Why do you call external models to do it? You can do it yourself!"
+
+Fill in the `en` field for every entry. Batch if needed, but translate in your response, not via API calls.
+
+Terminology guidance for Buddhist/gratitude content:
+- 感恩=gratitude, 缘起=dependent origination, 众生=sentient beings
+- 因缘=causes and conditions, 三宝=Three Jewels, 福报=merit/blessings
+- 座上=formal practice, 座下=daily life practice, 共修=group practice
+- 上报四重恩=repaying the four great kindnesses
+
+### 3. Quality review
+
+Scan for:
+- Terminology consistency (same zh term → same en term throughout)
+- Ellipsis convention — English uses 3 dots `...`, zh may use 6
+- Buddhist term accuracy
+- Missing translations
+- Overly literal renderings
+
+### 4. Write back with layout fixes
+
+Run `scripts/build.py strings.yaml original.pptx translated.pptx`.
+
+The script:
+- Replaces text in matching paragraphs (clears all runs, sets first run)
+- Replaces table cell text (using row/col from computed index)
+- Reduces font size by 18% (`FONT_SCALE = 0.82`) on all translated shapes and tables
+- Sets `auto_size = TEXT_TO_FIT_SHAPE` on text frames to handle overflow
+- English text is ~1.3–1.5× longer than Chinese — font shrink + auto-fit handles most cases
+
+## Alternate scripts
+
+The absorbed `pptx-translation` skill had alternate script names: `extract_pptx.py` and `build_pptx.py`. These are functionally equivalent to `extract.py` and `build.py` with minor formatting differences (docstrings, variable naming). If the primary scripts fail, the alternates are available in the archive at `~/.hermes/skills/.archive/pptx-translation/scripts/`.
+
+## Pitfalls
+
+- "run" in the YAML is actually the **paragraph index** within a text frame, not the OOXML text-run index. python-pptx iterates paragraphs, not runs.
+- Font shrink only applies to runs that have an explicit `font.size` — inherited sizes from paragraph/layout defaults are skipped.
+- After write-back, verify with `python -m markitdown translated.pptx` to check text landed correctly.
+- Tables: font shrink is applied per-cell text frame. Each cell is its own text frame.
+- markitdown may fail with `ModuleNotFoundError: dotenv` — run `pip install python-dotenv` first.
+
+## Scripts
+
+- `scripts/extract.py` — extract strings from PPTX to YAML
+- `scripts/build.py` — write translations back with font shrink + auto-fit
