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

Annotations already declare destructiveHint=true and readOnlyHint=false, but the description adds genuinely non-obvious behavior: creation lands in a disabled state, enablement requires an MCP confirmation step, and the webhook URL is disclosed only once. The one-time URL disclosure is critical for an agent to avoid losing a secret. It stops short of 5 because delete irreversibility and what happens to existing config on edit are not spelled out.

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?

A single dense sentence with zero filler, and the lifecycle ordering is front-loaded. It is slightly telegraphic — 'URL shown once' has no stated subject — but nothing is wasted.

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 7-parameter, destructive, multi-action tool with no output schema and no parameter documentation, the description covers the lifecycle and the one-time URL but leaves the input contract largely unexplained. An agent could pick the right action but would likely mis-populate idempotency_key or input_template.

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?

Schema description coverage is 0% across 7 parameters, so the description carries the full burden and largely fails it. It maps its verbs to the action enum, but says nothing about workspace, idempotency_key (required, 8-128 chars), agent, trigger, name, or the input_template object — an agent has no idea what input_template should contain.

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?

The description names a specific resource (teammate webhook) and enumerates the exact lifecycle verbs that map onto the action enum: create, edit, enable, disable, delete. It is clearly distinct from agent_triggers_list, though it does not name the sibling explicitly, keeping it short of a 5.

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?

Useful implied guidance is embedded in the parentheticals — create produces a disabled webhook and enable requires MCP confirmation — which tells the agent the intended sequence. However, there is no explicit statement of when to pick this over agent_triggers_list or agents_save, and no prerequisites such as required permissions or workspace scoping.

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