Create a new section only if nothing fits. 2. **Format** — use the existing bullet style: `- [Title](URL) — One-sentence description. (source-context)` 3. **Deduplicate** — if the URL already exists in the file, update the description instead of adding a duplicate. 4. **TODO section** — if the reference is speculative or needs further review, place it under the `## TODO` section at the bottom instead. 5. **No prompting** — do not ask the user whether to add the reference. Just add it. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/matteing) — claim your Tome and manage your conversions.
