## When to Use

Use `DeleteProjectNote` only when:

- the user explicitly wants a note deleted,
- the note was created by mistake,
- the note is duplicate/noise,
- the note contains incorrect/sensitive information that should not remain,
- deletion is clearly better than editing.

---

## Recommended Workflow

```text
1. GetProjectNote.
2. Confirm the note content and Project association.
3. Ask for explicit confirmation if the user has not already confirmed deletion.
4. Run DeleteProjectNote.
5. Optionally create a new Project Note explaining the deletion, if appropriate.
```

---

## Delete vs Edit

Prefer `EditProjectNote` when the note should be corrected.

Use `DeleteProjectNote` when the note should no longer exist.

| Need | Correct Operation |
|---|---|
| Fix typo or add missing ID | `EditProjectNote` |
| Correct wrong context | `EditProjectNote` or create a clarifying note |
| Remove duplicate note | `DeleteProjectNote` |
| Remove note created by mistake | `DeleteProjectNote` |

---

## Warning

Deleting notes can remove useful history for future AI/MCP interactions.

Important:

```text
Do not delete Project Notes casually.
```

---

## Final AI/MCP Instruction

Use `DeleteProjectNote` only after reviewing the note and confirming deletion is intended. Prefer editing or adding clarifying notes when preserving history is better.
