debug_pause

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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it reveals nothing about side effects, reversibility, whether the operation is synchronous or asynchronous, or the resulting debugger state. The schema hints at thread-targeted pausing, yet the description adds no behavioral context beyond the bare act of pausing.

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 words is under-specification rather than conciseness; the single clause is trivially front-loaded but carries almost no information. Consistent with the 'Process' calibration, brevity that omits essential content earns a low score because the sentence does not meaningfully earn 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 control-flow mutation tool with no output schema and no annotations, the description should state the post-condition (execution suspended, where the program stops), how to resume via debug_continue, and what state the session must be in before calling. None of this is present; the agent must reconstruct the entire debug workflow from sibling tool names alone.

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 session_id and thread_id are already documented in the schema and the baseline is 3. The description itself contributes no parameter semantics — it does not mention that pausing can target a stopped thread or that a session_id is required, so it neither compensates nor adds value beyond the 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?

"Pause execution" states a specific verb and resource, so the basic action is identifiable. However, it is nearly a restatement of the tool name, does not clarify whether pausing targets the whole session or a specific thread, and provides no differentiation from the 16 sibling debug tools. The schema exposes a thread_id parameter that implies thread-scoped pausing, but the description is silent on this.

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 no guidance on when to use pause versus alternatives like debug_continue, debug_step_over, or debug_get_pending_events. No prerequisites (e.g., an active or running session), timing conditions, or exclusions are mentioned. An agent receives zero routing information from the text.

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