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

No annotations are provided, so the description carries full burden for behavioral disclosure. While 'upload, delete, or modify' implies mutation capabilities, it doesn't specify permissions required, whether operations are reversible, rate limits, or what happens on success/failure. For a tool with multiple actions including destructive ones, this is a significant gap in safety and operational context.

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 extremely concise at three words, front-loaded with the core actions. There's no wasted text, though it could benefit from slightly more context given the tool's complexity. Every word earns its place by listing the key operations.

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 (multiple actions including destructive operations), lack of annotations, and no output schema, the description is incomplete. It doesn't address behavioral traits, usage context, or return values, leaving significant gaps for an AI agent to understand when and how to invoke it safely and effectively.

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 description coverage is 100%, so the schema already documents all three parameters with their types, enums, and requirements. The description adds no additional meaning about parameters beyond what's in the schema (e.g., it doesn't explain what 'modify' entails or how 'count' differs from other actions). Baseline 3 is appropriate when schema does the heavy lifting.

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 'Upload, delete, or modify activities' clearly states the tool's purpose with specific verbs (upload, delete, modify) and resource (activities). However, it doesn't distinguish this tool from its siblings like 'get_activities' or 'create_running_workout', leaving ambiguity about its specific role versus other activity-related tools.

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 provides no guidance on when to use this tool versus alternatives. With siblings like 'get_activities' (for retrieval), 'create_running_workout' (for specific creation), and 'update_health_data' (for modifications), there's no indication of when this multi-action tool is preferred over more specialized ones or what prerequisites might be needed.

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