centrex_delete_contact

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

With no annotations, the description identifies the operation as destructive and notes a config requirement. It could be more explicit about irreversibility or side effects, but the core behavioral trait is conveyed.

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?

Two concise sentences, front-loaded with the action and followed by a critical prerequisite. No unnecessary words.

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 simple delete operation with one parameter and no output schema, the description is adequate. It covers the action and a key prerequisite. Could add a note about immediacy or confirmation.

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 only parameter (contact_id) is already fully described in the schema (100% coverage). The tool description adds no additional meaning beyond what the schema provides.

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?

Clearly states the action (delete) and resource (contact from Centrex CRM). Distinguishes from sibling tools like centrex_create_contact and centrex_list_contacts.

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?

Explicitly mentions the required config flag (CENTREX_ALLOW_DESTRUCTIVE_OPERATIONS=true), providing a clear prerequisite. However, it does not mention alternative actions or when not to use.

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