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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description usefully discloses what the call returns (steps, transfers, parameters, metadata), but says nothing about permissions, pagination, or behavior on a missing/invalid ID.

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 the action and lookup key front-loaded and the return contents second. No filler, though the return-value sentence doubles as compensation for the absent output schema rather than pure economy.

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 single-param read tool with no output schema and annotations covering safety, the description discloses the returned payload shape (steps, transfers, parameters, metadata), which is exactly the gap an output schema would otherwise fill. Routing to alternatives is the only missing piece.

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% for the single 'id' parameter, so the schema already documents it fully and the description adds only the 'by ID' framing. Baseline 3 is appropriate when the schema carries the parameter semantics.

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 (Get) and resource (protocol template) scoped by ID, and enumerates the returned content. It distinguishes itself from list_protocols (plural listing) and get_protocol_run (a run instance), though it never explicitly names those siblings to remove ambiguity with get_protocol_forks or validate_protocol.

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 'by ID' phrasing implies it is a lookup, but there is no statement of when to use this instead of list_protocols, get_protocol_run, or get_protocol_forks, and no prerequisites or exclusions. Guidance is essentially absent.

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