set_debug_pause

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

Annotations already declare a non-destructive mutating, open-world operation, and the description is consistent with that (it toggles runtime state only). The line 'Captures do not change pause state' adds genuine behavioral context about interaction with sibling capture tools, but prerequisites (active session, whether pausing halts the target process) are unstated.

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 short sentences, front-loaded with the core action; nothing is redundant. The second sentence is slightly cryptic in isolation ('captures' is undefined) but does carry real information.

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?

With no output schema and only annotations for the safety profile, the description should cover session prerequisites and the boolean's semantics; it covers neither fully. It is minimally adequate for a simple two-parameter toggle but leaves the caller to guess preconditions and polarity.

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 only 50%: sessionId is documented but the required boolean 'paused' has no description. The description says 'pause or resume' but never states the polarity (paused=true means pause, false means resume), which is exactly what an agent needs for the one required parameter.

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 pair ('pause or resume') and resource ('the live debug session'), which is enough to distinguish it from siblings like step_frames, capture_screenshot, and start_debug_session. No explicit sibling callout, but the resource and scope are unambiguous.

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 'live debug session', but the description never says the session must already be running, nor when to prefer this over step_frames or capture tools. There is no exclusion or alternative named.

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