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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states that disabling tracing preserves the log for inspection via 'get_trace,' which adds some context about post-operation behavior. However, it doesn't cover critical aspects such as whether this requires specific permissions, if it's reversible, potential side effects, or error conditions, making it insufficient for a mutation tool with zero annotation coverage.

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 appropriately sized and front-loaded, starting with the core purpose in the first sentence, followed by additional context and parameter details. Every sentence earns its place by providing essential information without redundancy, making it efficient and well-structured.

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?

Given the tool's complexity as a mutation tool with no annotations and no output schema, the description is minimally adequate. It covers the purpose and parameter semantics but lacks details on behavioral traits, return values, or error handling. This leaves gaps in completeness, though it meets a basic threshold for a single-parameter tool.

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 description includes an 'Args' section that documents the single parameter 'session_id,' adding meaning beyond the input schema, which has 0% description coverage. This compensates well for the schema's lack of descriptions, as it clarifies the parameter's purpose. Since there's only one parameter, the baseline is high, and the description fully addresses it.

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 clearly states the tool's purpose with 'Disable execution tracing,' which is a specific verb+resource combination. It distinguishes itself from siblings like 'enable_trace' by indicating an opposite action, though it doesn't explicitly differentiate from all related tools like 'save_trace' or 'get_trace' beyond mentioning the latter. This makes it clear but not fully sibling-differentiated.

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 description implies usage by mentioning that 'The trace log is preserved for inspection via get_trace,' suggesting this tool is used to stop tracing while keeping logs accessible. However, it lacks explicit guidance on when to use this versus alternatives like 'enable_trace' or 'save_trace,' and doesn't specify prerequisites or exclusions, leaving usage context somewhat inferred.

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