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

No annotations are provided, so the description carries full burden for behavioral disclosure. It mentions return values (trust score, grade, security findings) but fails to disclose important traits such as whether the scan is destructive, whether it modifies state, expected duration, rate limits, or if results are cached. The verb 'Trigger' implies a side effect but lacks detail.

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 extremely concise with two short sentences, front-loading the action verb 'Trigger'. Every word serves a purpose; there is no redundancy or filler.

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-parameter tool with no output schema and no annotations, the description adequately states the action and return type. However, it could provide more context about scan duration, whether results are stored, and how it differs from siblings like check_trust. Given the presence of sibling tools, more distinction would improve completeness.

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?

With 100% schema coverage, the schema already documents the single parameter (server_url) sufficiently. The description adds no additional meaning beyond what the schema provides, meeting the baseline expectation but not going beyond.

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 clearly states the tool triggers a live trust scan of an HTTP/HTTPS MCP server and returns trust score, grade, and security findings. It uses a specific verb ('Trigger') and resource ('MCP server'), and distinguishes from siblings like check_trust (likely checking existing trust) and search_registry (searching).

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?

The description implies when to use (to perform a scan) but does not explicitly state when not to use or provide comparisons with siblings like check_trust or get_stats. There is no guidance on prerequisites or frequency limits, leaving the agent to infer context.

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