The Builder agent can edit existing notes in your vault without rewriting them from scratch. It uses a unified diff patch system that modifies only the specific lines that need to change, leaving the rest of the file untouched.
Example prompts
Update the note "Project Kickoff" to add a section on risks and mitigation.
In the note "Python Functions", fix the code example in the "Lambda" section to include a practical use case.
Rename the heading "Overview" to "Executive Summary" in the note "Q3 Strategy".
How patches are applied
- The Planner reads your vault structure to locate the note.
- The Builder applies a
patch_vault_file directive — only the changed lines are modified.
- The Critic reviews the result and either approves it or sends it back for revision.
- The Audit Log records the before and after SHA256 hash of the file so you can verify exactly what changed.
For destructive changes — deleting entire notes or major rewrites — back up your vault first. Use the Audit Log (accessible from the sidebar) to review recent changes and their before/after checksums.
Deleting notes
You can also ask agents to delete files from your vault:
Delete the note "Draft - Unused Ideas" from the vault.
deleted status. The operation is not reversible through the app, so make sure you no longer need the file before asking for a deletion.
