set_debug

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

With no annotations provided, the description carries the full behavioral burden, and it discloses nothing: not whether debug mode persists, what it changes (logging verbosity, console capture), whether it is safe or reversible, or who can call it. A mutation-style setter with zero disclosed behavior.

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?

Extremely short and front-loaded with no wasted words, but the brevity reflects under-specification rather than efficiency. It is appropriately sized only because it says almost nothing.

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?

The tool is structurally simple (one boolean), but with no annotations and no output schema, the description should at least explain the observable effect of toggling debug mode and its persistence. That is entirely absent, leaving the agent unable to predict the call's consequences.

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 0% and the description says nothing about the single 'enabled' boolean beyond what the name implies. Booleans are largely self-documenting, which prevents a 1, but the description adds no value over 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?

States a verb ('Set') and resource ('debug mode'), which is more than a tautology, but it doesn't distinguish itself from siblings like set_config or console_logs, nor does it say what debug mode governs. The purpose is inferable but thin.

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?

No indication of when to enable debug mode, what it affects, or how it relates to set_config or console_logs. The agent gets no context for choosing this tool over the config setter.

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