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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the mutation profile is covered. The description adds the target state ('editable draft'), which tells the agent the review state is discarded, but says nothing about permission requirements, reversibility, or what happens to approvals already collected.

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 twelve-word sentence that front-loads the action and the resulting state. Nothing is padded or redundant.

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 destructive state-transition tool with no output schema, the description covers the essential who/what but not the surrounding conditions: no permissions note, no behaviour for an already-draft deliverable, and no mention of side effects on related approvals. Adequate minimum viable, with clear gaps.

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 single required parameter 'deliverable_id' is never mentioned in the description. With one obvious identifier parameter the omission is less harmful than it would be for a multi-param tool, but the description does not compensate for the documentation gap.

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 ('Return ... to editable draft status') and a specific resource ('review deliverable'), so an agent can tell it apart from approve_consulting_deliverable, submit_consulting_deliverable, and update_consulting_deliverable. It does not name those siblings explicitly, which keeps it short of a 5.

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 qualifier 'unapproved' implies the applicable precondition (the deliverable must currently be in a review state), which is genuine usage guidance. However, there is no statement of when to prefer this over update_consulting_deliverable or what to do if the deliverable is already a draft.

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