toggl_create_time_entry

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

With no annotations, the description must disclose behavioral traits, but it only states 'create'. It fails to mention authorization requirements, side effects, whether the entry is immediately persisted, or any constraints like time format. This is insufficient for a creation tool.

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 (one sentence), but this brevity comes at the cost of critical detail. It is front-loaded with the core action, but lacks structure that would benefit an agent (e.g., bullet points, required fields note).

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 no output schema and no parameter descriptions, the description should provide a complete picture of the tool's usage, but it omits essential behavioral and semantic details. It is inadequate for an agent to use correctly without external knowledge.

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 0%, yet the description adds no meaning to any of the 6 parameters (e.g., workspace_id, start, api_key). The agent gains no insight into parameter roles, formats, or dependencies, forcing reliance on the bare 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 clearly states the action ('create') and the resource ('new Toggl time entry'), with an explicit verb and resource that distinguishes it from sibling tools like toggl_time_entries (which lists entries) and toggl_projects.

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 guidance is provided on when to use this tool versus alternatives, such as updating or deleting entries, or prerequisites like having a valid workspace_id. The description lacks any context for appropriate usage.

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