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

Annotations already declare destructiveHint=true, idempotentHint=false, and readOnlyHint=false, so the safety profile is largely covered. The description adds one genuinely useful behavioral fact — that MCP approvals are administrator-configurable while business workflow approvals always apply — but says nothing about what the destructive update overwrites, whether omitted fields are cleared, or whether partial updates are supported.

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 with the usage condition front-loaded, so it is not bloated. However, the first sentence is vague filler and the approval boilerplate, while useful, crowds out more important content such as which fields are editable.

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?

This is a destructive mutation with a deep nested schema and two required parameters, yet the description omits the two things an agent most needs: which fields may be updated and how `data` is applied. An output schema exists so return values need not be explained, but the input-side gap is significant.

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% and the nested `data` object exposes roughly twenty fields with no documentation anywhere. The description's only contribution is the phrase "allowed fields," which implies some fields are non-updatable but never identifies which ones, and it does not clarify merge-vs-replace semantics for `data`.

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?

The description names a verb and resource ("Update allowed fields of task"), which is more than a tautology, but "allowed fields" is left undefined and nothing distinguishes it from the many sibling update tools such as update_project_task or update_checklist_item. An agent knows it mutates a task record but not which task entity or field set separates it from its neighbors.

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?

"Use this when working with RetailHardHat tasks records in the connected organization" is a generic scope statement rather than a usage condition. There is no guidance on when to prefer this over update_project_task, update_phase, or update_checklist_item, and no exclusions or prerequisites beyond the boilerplate approval sentence.

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