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

Annotations already declare the safety profile (readOnlyHint=false, destructiveHint=false, openWorldHint=false, idempotentHint=false). The description adds no behavioral detail beyond that – nothing about what happens after submission, whether a reply is expected, or delivery timing. With annotations carrying the safety burden, a 3 is appropriate.

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 sentences, front-loaded with the core action and then the use cases. There is mild redundancy between "send feedback..." and "Use this to tell us...", but nothing is wasted and the intent is immediately clear.

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 one-shot submission tool with full schema coverage and a complete annotation set, the description is sufficient; no output schema is needed since a feedback send has no meaningful return contract. It could mention that submissions are one-way, but nothing critical is missing.

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 100%, so the schema fully documents the type enum, message, and nested context object. The description adds no parameter-level meaning (e.g., how much detail the context fields need or which fields pair with which type), so the baseline 3 applies.

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?

States a specific verb (send) plus resource (feedback) and the recipient (LinkMCP team), then enumerates the concrete payloads (feature requests, bug reports, help requests). It is unmistakably distinct from every LinkedIn sibling, which all operate on LinkedIn data rather than contacting the team.

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?

"Use this to tell us what is working well, what could be improved, to request new features, or to ask for help" gives clear positive-use context that maps to the enum types. It does not state when-not to use it or name any alternative, but the tool's role is unique among the siblings so ambiguity is low.

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