Ensure Clockify task

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

There are no annotations, so the description carries the full burden. It transparently discloses the main side effect ('or creates it'), which is important, and adds the user-scoped config_root concern. However, it does not describe return behavior, exact-match/duplicate behavior, or failure cases, so the behavioral disclosure is only partial.

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 two focused sentences: the first explains behavior with a useful example, and the second provides configuration guidance. Every sentence adds value, and the main semantics are front-loaded.

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?

The description plus a fully covered schema is sufficient to invoke the tool correctly: required params are clear, config_root usage is clarified, and the find-or-create semantics are stated. It would be stronger with return-shape or sibling-routing details, but nothing essential prevents correct use.

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 parameters are already well documented. The description adds some context about config_root usage, but it mostly reinforces the schema rather than adding significant new parameter meaning. Baseline 3 is appropriate.

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 uses a specific verb phrase: 'Finds a task by name under a project or creates it', which precisely captures the ensure/find-or-create behavior. It also gives a concrete use case ('sync a GitHub label') and is clearly distinct from siblings like list_tasks or ensure_project because list_tasks only lists and ensure_project targets projects, not tasks.

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 gives clear context for when the tool is relevant and specifically instructs when config_root is needed: 'when this MCP is user-scoped'. It does not explicitly name alternate tools or say when not to use it, so it stops short of a full 5.

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