clickup_stop_time_tracking

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

With no annotations, the description carries the full burden. It discloses the return outcome ('Returns the completed time entry details') and that description/tags are applied to the entry, which is real added context, but says nothing about failure modes (no active timer), idempotency, or permission requirements for a mutation.

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?

Three short sentences, zero waste, with the core action front-loaded followed by accepted inputs and return behavior in a logical order.

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?

Adequate for a simple mutation: it covers action, inputs, and return value without an output schema needing further explanation. However, edge-case behavior (no running timer, behavior of tags on the completed entry) is left unstated for a no-annotation tool.

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 all three parameters are already documented in the schema, making 3 the baseline. The description's mention of 'description and tags' merely restates two schema fields and adds no semantics for workspace_id.

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?

States a specific verb and resource ('Stop the currently running time tracker') with scope ('currently running'), which cleanly separates it from clickup_start_time_tracking and clickup_add_time_entry. The follow-on sentences add what it accepts and what it returns.

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?

Usage is implied by 'currently running' – the agent can infer this applies only when a timer is active – but there is no explicit when-to-use, no mention of what happens if no timer is running, and no named alternatives such as add_time_entry for manual logging.

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