stop_session

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

Description claims read-only, stateless, and no side effects, which contradicts the action implied by the tool name 'stop_session' (a state-changing operation). Annotations are absent, so description carries full burden but misleads.

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?

Description is lengthy with repetitive sections; the first sentence is concise but followed by irrelevant bulk (Behavior, When to use/not, Behavioral Transparency) that should have been tailored to the tool.

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?

Lacks crucial details like how the session is stopped, effects on timers, or output structure despite having an output schema; entirely incomplete for a state-changing 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?

Parameter descriptions in the 'Args' section are generic ('The completed to analyze or process') and add no meaningful context beyond the schema; with 0% schema description coverage, this fails to compensate.

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?

First sentence clearly states 'Stop the current Pomodoro session', but subsequent text describes a read-only analysis tool, creating confusion about the actual purpose.

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?

When-to-use and when-not-to-use sections are about analysis/classification, irrelevant to stopping a session; no guidance relative to sibling tools.

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