Compare with a Saved Snapshot
compare_with_previousRead-onlyIdempotent
Diff the current session against a previously saved snapshot of the same solution to find added/removed types and methods, optionally narrowed to one type or method.
Instructions
Diff the current session against a previously saved snapshot of the SAME solution - the newest by default, or the N-th previous via snapshotsBack (0=newest saved, 1=the one before, ...). Optionally narrow the diff to a single type and/or method. Returns added/removed types plus, per changed type, added/removed methods and signature changes. Requires a sessionId and at least one earlier save_session; dbPath is optional and defaults to the server's standard config DB when omitted. Name-based, syntactic (no method-body diff).
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| dbPath | No | Optional absolute path to the aicb SQLite DB holding the saved snapshots. Omit to use the server's standard config DB. | |
| typeName | No | Optional: restrict the diff to this type (simple name, case-insensitive). Omit for the whole-solution diff. A simple name ALSO matches the namespace-qualified form the diff renders for a type whose simple name collides in the solution - then the answer spans every type of that name and 'note' says which; pass one of those qualified names to narrow to a single type. Not a substring match: 'MyApi' never matches 'MyApiExtensions'. When a filter EMPTIES a diff that did have changes, 'note' says so and names the axis that missed, because 'isIdentical: true' then describes the filtered view and not the solution. On a diff that was ALREADY empty there is no note and none is owed: 'your filter matched nothing' and 'nothing changed' are the same state there, so a typo'd name and a real one answer identically - check the spelling with find_symbol rather than reading that agreement as confirmation. | |
| sessionId | Yes | The current session_id (the 'after' side of the diff). Also takes an absolute .sln/.slnx/.slnf path, analyzed on first use. | |
| methodName | No | Optional: within that type, restrict to this method name (case-insensitive). Omit for all methods of the type. Same disclosure rule as typeName: if the type matched and this name matches none of its added/removed/signature-changed methods, the type is dropped from the answer and 'note' says which of the two filters came up empty - an empty view here is never evidence that the method is unchanged. | |
| snapshotsBack | No | 0 = newest saved snapshot, 1 = the one before it, etc. (index into the per-solution history, newest first). |
