Freelo Start Time Tracking

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

Beyond the annotations, the description reveals that the tool creates a persistent active timer that runs until explicitly stopped. It also implies non-idempotency by describing an ongoing state. It does not mention what happens if a timer is already running, which is a minor gap, but the core behavioral trait is well disclosed.

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 compact sentences with no filler. The first sentence states the primary action and the second describes the lifecycle and names the stopping tool. Every sentence earns its place.

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 simple tool with one optional parameter, an output schema, and clear annotations, the description is nearly complete. It could mention behavior when a timer is already active, but the combination of description, schema, output schema, and sibling context is sufficient for correct invocation.

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 input schema already fully documents the only parameter, taskId, including its optionality and fallback behavior. The description does not add parameter-level detail, so the baseline of 3 applies since schema coverage is 100%.

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 ('Starts real-time time tracking'), the resource (a task), and the resulting behavior (an active timer). It also explicitly names the sibling tool freelo_stop_time_tracking, which distinguishes this tool from its counterpart and clarifies its scope.

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: use this for real-time tracking and stop it with freelo_stop_time_tracking. It does not explicitly mention alternatives like manual work reports or edge cases, but the sibling pairing and real-time framing provide sufficient guidance for when to use it.

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