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. The description adds genuinely new behavioral requirements beyond that: a human-confirmation step and the provenance of valid ids. It doesn't cover edge behavior (e.g., removing a nonexistent id), so not a 5.

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?

Three short sentences, zero filler, with the destructive action and its precondition front-loaded. Every sentence carries actionable information.

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 destructive tool with rich annotations and no output schema, the description covers purpose, id source, and the confirmation guardrail. Nothing an agent needs to invoke it safely 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 coverage is 100% with a single documented string param (24-hex pattern), so the baseline is 3. The description adds real meaning by telling the agent where the savedJobId value comes from (get_saved_jobs), which the schema does not state.

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+resource ("Remove a job from the user's saved list") that is unambiguously the inverse of the sibling save_job, so an agent can route correctly without opening a schema. No vague or tautological phrasing.

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?

Gives concrete usage context: it names get_saved_jobs as the source of valid ids and instructs the agent to confirm with the user first. It lacks an explicit when-not or alternative-tool clause (e.g., how this differs from unstar_listing), which keeps it short of a 5.

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