connect_clockwork

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

No annotations are provided, so the description carries the full behavioral burden. It discloses that the tool verifies API reachability and authentication, and that it caches the connection for later calls. This is meaningful operational detail, though it does not cover error behavior or cache lifetime.

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?

Two sentences with no wasted words. The primary action and verification behavior are front-loaded, and the note about sibling tools earning its place by preventing unnecessary connect calls.

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 zero-required-parameter setup tool with fully documented schema, the description covers purpose, verification, caching, and the alternative invocation pattern. It does not explicitly describe the case when no parameters are provided, but the param descriptions already reference environment/local storage fallback.

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 schema already documents all four parameters at 100% coverage, so the baseline is 3. The description groups the parameters and notes they are shared with sibling tools, which is useful cross-tool context, but it does not add deeper meaning about format, precedence, or edge cases beyond the schema.

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 opens with a specific verb and resource: 'Connect to a Clockwork application', and immediately clarifies the optional password aspect. It clearly distinguishes this tool from the sibling data-retrieval tools by framing it as the connection-setup action.

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?

It states that the connection is cached for subsequent calls and that all other tools accept the same parameters directly, giving the agent a clear alternative. It does not explicitly spell out when to choose connect_clockwork over direct parameter passing, but the caching benefit is strongly implied.

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