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

With no annotations, the description must carry the behavioral burden. It discloses that the operation appends rather than rewrites, which is a key behavioral trait. However, it doesn't explain side effects, idempotency, or what happens to existing data beyond the append nature. Minimal but non-zero transparency.

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?

Very concise: two short sentences with no filler. The key behavioral trait is front-loaded. Could be slightly more explicit about parameters, but structure is efficient.

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 tool with 4 parameters, no annotations, and an output schema, the description is too sparse. It doesn't explain how to provide the required parameters or what the output represents. The agent would need to inspect the schema deeply and still lack context on usage semantics.

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 0%, so the description must compensate. It mentions 'bounds' which maps to start/stop, but gives no explanation of the required 'effort' and 'interval' parameters. The agent cannot infer how to specify which interval to correct or what effort context is needed.

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 ('Correct') and resource ('an interval's bounds'), and adds a distinguishing behavioral trait ('Appends; never rewrites'). This clearly separates it from sibling tools that start, slice, or record actions, though it doesn't name alternatives explicitly.

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?

No explicit guidance on when to use this tool versus alternatives. It implies use when bounds need correcting, but doesn't state conditions, exclusions, or mention sibling tools. The agent is left to infer the appropriate context.

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