things_create_task

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

Annotations already declare destructiveHint=true, idempotentHint=false, and readOnlyHint=false; the description reinforces the non-idempotent risk with an explicit duplicate-creation caution, which is valuable context. It also discloses that the created task is read back (relevant since there is no output schema). It stops short of stating permissions or the exact return payload.

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 destination, followed by a single high-value operational caveat. No filler; each clause earns its place.

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 create tool with annotations covering the safety profile, the description covers default behavior, destination override, read-back, and duplicate-avoidance. Missing param-level detail (deadline format, tags/notes semantics) keeps it from being fully complete, but nothing critical to calling it safely is absent.

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% across 6 parameters, so the description must carry the load. It only hints at the project_id/area_id destination choice via 'in Inbox, or a specified project/area' and says nothing about title, tags, notes, or especially the deadline string's expected format. Better than nothing but leaves most parameters undocumented.

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 (create) and resource (task) plus the destination semantics: Inbox by default or a specified project/area. This naturally separates it from the update/move/complete/get/list siblings. It does not explicitly name or contrast a sibling, so it falls just short of the top mark.

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: the default landing spot is Inbox, and a project/area can be targeted instead. It also supplies a when-not rule for a failure mode ('do not retry an ambiguous failure without searching for the created task'), which implicitly routes the agent to a search/get sibling. No explicit alternative tool is named, so not a 5.

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