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

No annotations provided; description only states that it executes instructions and outputs a summary. It does not disclose whether execution modifies state,what the side effects are, or any required permissions. This is minimal 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?

The description is a single sentence, front-loaded with the main action. It is concise with no wasted words, though it could be slightly more structured for clarity.

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 tool with one parameter and no output schema, the description covers the basic purpose and parameter meaning. However, it lacks details on usage context, state changes, and output format, which are needed for full completeness given the sibling tools.

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?

The single parameter 'count' has a description in the tool description (number of instructions, default 1) which adds meaning beyond the schema's type and default. Schema description coverage was 0%, so the description compensates adequately.

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?

Description clearly states it executes instructions and outputs a summary. The verb 'execute' and resource 'instructions' are specific. It distinguishes from sibling 'run' by mentioning a specific count, though the exact nature of instructions is implicit.

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 guidance on when to use this tool versus alternatives like 'run' or 'add_input'. The description does not mention when to choose step over siblings, leaving the agent to infer usage context.

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