add_dialer_suppression

Idempotent

Add a number to the workspace suppression list: no campaign will ever dial it (optionally until expires_at).

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A3.5/5.0
Behavior3/5

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

Annotations already declare idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds real value by disclosing the durable, workspace-wide effect of the entry, but it omits what happens on duplicate submission, whether an existing suppression can be removed, and any permission requirements.

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?

A single sentence that front-loads the action and follows immediately with the consequence. No filler, though the parenthetical about expires_at is slightly awkwardly placed at the end.

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 a simple four-parameter create tool with full schema coverage, annotations, and no output schema, the description covers the essentials: what it adds, the scope (workspace), and the permanence option. It falls short only on duplicate handling and reversal, which an agent running a suppression workflow might reasonably need.

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 description coverage is 100%, so phone, reason, purpose, and expires_at are all documented in the schema already. The description's mention of "optionally until expires_at" restates the schema's "omit for permanent" without adding new format or constraint detail, so baseline 3 applies.

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 names a specific verb and resource ("Add a number to the workspace suppression list") and states the concrete consequence ("no campaign will ever dial it"). That effect cleanly distinguishes it from contact-adding siblings such as add_dialer_contacts, though no sibling is named explicitly.

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?

The context of use is implied by the suppression effect and the optional expires_at, so an agent can infer this is a do-not-call tool. However, there is no explicit when-to-use guidance, no mention of when to prefer permanent vs. expiring suppression, and no pointer to any alternative or follow-up tool.

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