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

Annotations already declare readOnlyHint=false, destructiveHint=false, openWorldHint=true and idempotentHint=false, and the description adds nothing on top of them. Notably it never explains that a required idempotency_key is needed for retry safety — a real tension with idempotentHint=false — nor that workspace_id becomes required for this creation call, both of which are material behaviors for a write tool.

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. It is efficient, but the brevity is partly under-specification rather than disciplined compression.

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 13-parameter, nested-object creation tool with an openWorld hint and no output schema, a single sentence is insufficient. An agent is left without guidance on the mandatory idempotency_key, workspace_id requirements, linking constraints, or what a successful creation returns.

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 85%, so the schema already carries most parameter meaning and a baseline of 3 applies. The description contributes at most a weak nod to workspace scoping ('in the workspace') and says nothing about the undocumented idempotency_key, the linked_idea_id/linked_post_id mutual exclusion, or required vs optional fields.

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') with the workspace scope, which is enough for an agent to know what the tool produces. It does not, however, distinguish itself from the many other create_* siblings or say anything about the task's relation to posts/ideas.

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?

The description offers no when-to-use guidance, no prerequisites, and never names an alternative (e.g., create_post, create_idea, or update_task once the task exists). The agent must infer usage purely from the name.

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