Add broadcast

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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses the key idempotent no-op behavior, which is the main operational nuance an agent needs. Return values and error cases are not covered, but the tool is simple enough that this is a reasonable level of transparency.

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

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

The description is a single short sentence with the action and target front-loaded. The no-op clause adds important behavioral information without any unnecessary padding.

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

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

For a one-string-parameter tool with no output schema and no annotations, the description covers the core action, scope, and duplicate behavior. Parameter meaning and return/error behavior are implicit, but the tool is simple enough that no major contextual gap remains.

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

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

The schema has one required string `name` with 0% description coverage. The tool description implies that `name` identifies the broadcast message being added, but it does not explicitly state constraints, formatting, or uniqueness rules. It adds enough meaning to connect the parameter to the action, but does not fully compensate for the schema gap.

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

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

Description uses a specific verb ('Add') and a concrete resource ('broadcast message to the project'), and the no-op clause distinguishes it from other add_* siblings by describing duplicate behavior. It is immediately clear what this tool does and how it differs from related tools.

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

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

There is no explicit when-to-use or when-not-to-use statement, nor a named alternative. The wording 'to the project' and 'no-op if it already exists' implies this is the broadcast-specific add operation and is safe to call repeatedly, but the choice among add_* sibling tools is left to inference.

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