# list\_evidence\_catalog — List the org's canonical evidence catalog

List the org's canonical evidence catalog

List the org's canonical evidence catalog

## What it does

List the organization's canonical evidence-line definitions (across all models) — each a reusable line with its authored BxQL — so the agent can reuse established lines of evidence.

**When to use:** you need the org's library of evidence lines + the BxQL that defines each; you're assembling evidence and want to reuse a canonical definition rather than invent one.

**When NOT to use:** you want ONE model's evidence lines with their weights — use get\_reasoning\_model; you want the org's query-building instructions — use get\_ql\_instructions.

**Parameters:** none.

**Returns:** An object { entries, count }. Each entry is { displayName, description, category, bxql, usageCount } where bxql is the authored BxQL defining the line and usageCount is how many of the org's models use a line with this definition.

## Parameters

*No parameters.*

## Response

```ts
{
  entries: Array<{
    displayName: string;
    description: string | null;
    category: string | null;
    bxql: string | null;
    usageCount: number | null;
  }>;
  count: number;
}
```

## Example

```json
// list_evidence_catalog({})
{}
```

Response (arrays truncated):
