Get a broadcast

luca_broadcasts_get
Read-onlyIdempotent

Retrieve a broadcast's full details by ID, with optional workspace ID or slug override. Use it to review broadcast content and settings before drafting replies or reports.

Instructions

Get broadcast detail.

Luca operation: GET /api/broadcasts/{id} Required scopes: broadcasts:read Required OAuth scope: luca:read; data sensitivity: full_content Does not require idempotency. Use workspaceId or workspaceSlug to override the default workspace configured by environment.

TDQS

A3.7/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds genuinely new operational context: required scopes (broadcasts:read, luca:read), a data sensitivity level of full_content, and the workspace-defaulting behavior, which an agent could not infer from annotations or schema.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The definition is short and front-loads the purpose before the operational metadata. "Does not require idempotency" is slightly redundant against idempotentHint=true, but the line-oriented scope/sensitivity block is easy to scan and wastes little space.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For low-complexity single-resource read with an output schema, the description covers purpose, endpoint, auth scopes, sensitivity, and workspace scoping, which is enough to invoke it correctly. Only edge behavior such as not-found or error responses is left unstated, a minor omission given the output schema exists.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 67%: workspaceId and workspaceSlug are already described in the schema, and the description's workspace-override sentence largely restates them while adding the useful fact that a default workspace comes from the environment. The required `id` parameter has no schema description and is only explained implicitly through the path template, so the description does not fully compensate for the gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource ("Get broadcast detail") and backs it with the concrete endpoint GET /api/broadcasts/{id}, so the agent knows exactly which object is fetched. It does not explicitly contrast with the sibling luca_broadcasts_list, so single-vs-many selection is only implied by the word "detail".

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is only implied: needing one broadcast's detail by id selects this over the list tool. The only explicit guidance concerns workspace resolution ("Use workspaceId or workspaceSlug to override the default workspace configured by environment"), which is parameter advice rather than when-to-use vs alternatives or any when-not-to-use exclusion.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
