tasks_unlink

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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, so safety behavior is carried by structured data. The description adds that the operation targets a 'structured link' specifically, which clarifies scope, but it does not say what happens when the link does not exist (relevant given idempotentHint) or whether removal affects the linked artifact itself.

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 front-loaded sentence with no filler or redundancy. It is efficient, though its brevity contributes to the gaps in usage and behavioral detail rather than being maximally informative.

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 low-complexity, three-required-parameter tool with full schema coverage and annotations, the definition is technically callable. It still lacks the one piece of context an agent most needs — its relationship to tasks_link and the no-op-on-missing-link behavior — so it is adequate but not complete.

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%, including a documented id format and an enumerated set of link kinds, so the schema does the heavy lifting. The description adds no further meaning about the three required parameters, which is acceptable at baseline given the coverage.

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 and resource ("Remove a structured link from an item"), which is unambiguous on its own. However, it never names the obvious counterpart sibling tasks_link, so the agent gets no explicit differentiation between linking and unlinking beyond the verb.

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?

There is no when-to-use statement, no prerequisite information, and no reference to the sibling tasks_link that this tool reverses. The only guidance is the implied inverse of its name, leaving the agent to infer the workflow.

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