cal_setup_api

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

No annotations are provided, so the description carries the full burden of behavioral disclosure — and it discloses nothing. It does not state whether the tool writes files, modifies project config, stores the api_key somewhere (a security-relevant fact for a setup tool handling credentials), or requires any prerequisites before invocation.

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 six-word description ('Set up calendar API integration') nearly restates the tool name cal_setup_api, so this reads as under-specification rather than disciplined conciseness. The sentence is structurally fine but its entire content could be inferred from the name, meaning it earns no incremental value.

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 2 parameters, one undocumented, no output schema, and no annotations, the description is far from complete. An agent cannot correctly call this tool without knowing which calendar service is targeted, what the api_key is for, where the directory is used, and what side effects the setup produces.

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 only 50%: the directory parameter is documented but api_key has no description. The description adds nothing about either parameter — it never mentions which calendar provider the api_key belongs to, what format it takes, where the directory points, or what the tool does with these values.

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 names a domain (calendar) and a generic action (set up API integration), which is more than a tautology but still vague about what 'set up' concretely entails — credential exchange, SDK install, config file creation, or code generation. It does not define how it differs from adjacent siblings like cal_add_sync, cal_generate_ui, or oauth_setup_providers.

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 when-to-use guidance, no exclusions, and no mention of alternatives. With over 400 siblings including directly adjacent calendar tools (cal_add_sync, cal_generate_ui) and overlap-prone setup tools (oauth_setup_providers, auth_generate_oauth), the agent receives zero routing help for choosing this tool over its neighbors.

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