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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered without the description. The description only adds mild scope context (removal happens within the calling user's own lists), which is useful but thin; it says nothing about whether the underlying company/job data survives or how failures are reported.

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?

One short, front-loaded sentence with no filler or redundancy. Nothing could be trimmed without losing the core action.

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 two-parameter mutation with full annotation coverage and no output schema, the description is minimally adequate: the action and scope are clear. It stops short on identifier formats and on the recovery/discovery path (using list_lists to obtain list_id), which a caller genuinely needs.

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%, so the description carries the full burden and largely fails: it never clarifies whether "company" expects a name, slug, or ID, nor what list_id format is valid. "Startup" in the description also mismatches the schema parameter name "company", creating mild terminology drift.

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?

Specific verb ("Remove") plus resource ("a startup") and target container ("one of the user's lists"), so the action is unambiguous. It does not explicitly name add_to_list as the inverse sibling, but the verb pair makes the distinction obvious.

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?

No when-to-use guidance, no prerequisites, and no mention of the obvious alternative add_to_list or of list_lists (to discover list_id). The agent must infer the workflow entirely from the name.

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