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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and closed-world scope, so the safety profile is covered. The description adds real value by disclosing the payload shape (full flows JSON tree with rules, destinations, rotation), which matters since there is no output schema. It does not mention behavior for a missing 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?

One dense sentence with no wasted wording, and the key content (full flows JSON tree) is front-loaded. It is arguably too terse to hint at any caveats, but nothing is 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 simple single-entity read with full parameter documentation and rich safety annotations, the description covers the essential gap, which is what the response contains. Only error/not-found behavior and payload size expectations are missing.

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 carries the semantics. The description adds nothing about the id format or its relation to the JSON structure, so the 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?

The description uses a specific verb and resource (one flow scheme) and explicitly says it returns the full flows JSON tree containing rules, destinations and rotation. That distinguishes it from list_flow_schemes, though the sibling is not named.

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?

Usage is only implied: fetching a single scheme by id, as opposed to the plural list tool or update_flow_scheme. There is no explicit statement of when to prefer this over list_flow_schemes or apply_flow_scheme.

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