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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=false, so the write/safety profile is covered. The description adds nothing behavioral beyond restating that it creates — no mention of whether estate_id must pre-exist, validation failures, or what is returned. With annotations doing all the work, the description contributes little.

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 short sentences with zero filler; the action is front-loaded and the usage condition follows immediately. Nothing redundant or padded.

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 full schema coverage and a complete annotation set, the description supplies purpose and a trigger. The main gap is that no output schema exists and the description doesn't say what comes back (e.g., the new task's id), which an agent may need for follow-up calls.

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% and the schema itself documents defaults, the priority scale, enum values, and ordering semantics for after_task_id/blocked_by_task_id. The description adds no parameter meaning at all, 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 and resource ("Create a new task in the estate"), which clearly separates it from read/update siblings like get_tasks, edit_task, and update_task_status. It doesn't explicitly name those siblings or state scope constraints, so it's clear but not maximally differentiating.

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 a concrete trigger condition: "when the user identifies a new requirement or action item that should be tracked." That's real when-to-use guidance. It stops short of when-not-to-use or naming alternatives (e.g., edit_task for existing tasks, get_tasks to check for duplicates).

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