Stop timer

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

With no annotations, the description carries the full behavioral burden, and it explicitly discloses config-driven behavior: honoring entry_method rounding (end only), include_seconds, and overlap.on_conflict. It could also state what happens when no timer is running, but the disclosed specifics are concrete and useful beyond the schema.

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 front-loaded sentences with no filler: the main action first, followed by config-driven behavior and one environment-specific requirement. 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 stop-action with fully documented parameters, this description plus schema is nearly complete. It lacks a note about the no-running-timer edge case and the expected return value, but those are minor given the clarity of the description.

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 coverage is 100%, so the baseline is 3, but the description adds inter-parameter meaning by tying entry_method to rounding-on-stop and overlap.conflict behavior. The config_root note also clarifies when this parameter is relevant for user-scoped MCP setups.

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 first sentence uses a specific verb and resource ('Stops the currently running timer'), which clearly distinguishes it from siblings like clockify_start_timer and clockify_get_running_timer. This is not a vague restatement of the title.

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 phrase 'currently running timer' provides clear context for when to invoke this tool. It does not explicitly name alternatives or when-not conditions, but the context is strong enough to qualify as 'clear context, no exclusions'.

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