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

Annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=false, so the safety profile is carried by structured data. The description adds the key behavioral fact that ownership is *moved* (transferred away, not copied) via 'Move executable ownership', but it does not say what happens to the prior owner, whether the move is reversible, or what authorization the agent_key must satisfy beyond the schema hint.

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 front-loaded sentence with no filler; the transfer action and its target come first. It is efficient, though the compressed jargon ('executable ownership', 'contract family') costs a little immediate comprehension.

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 3-parameter, non-read-only tool with annotations but no output schema, the description covers the core action but omits prerequisites (manager authorization via agent_key), post-assignment state, and any failure conditions. Adequate as a minimum, but an agent must open the schema to understand what it needs.

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 coverage is 100%, so all three parameters are already documented. The description loosely maps 'contract family' to source_bounty_id and 'account you manage' to organization_id/agent_key, but adds no format, constraint, or edge-case detail beyond the schema. 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 ('Move executable ownership') and resource ('one accepted posted contract family') with a target ('a procurement account you manage'), so the assign action is inferable. It does not name or distinguish itself from the closely related siblings procurement_contract_run or contract_recovery, which an agent could plausibly confuse it with.

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?

There is no explicit when-to-use, when-not-to-use, or alternative routing guidance. The phrase 'a procurement account you manage' hints at a prerequisite but never states it as a condition, and nothing tells the agent why to pick this over procurement_contract_run.

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