set_operation_mode

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

With no annotations, the description carries full burden and does well: it explains the concrete behavioral consequence of autonomous mode (tool chaining without per-tool confirmation) and the important exception that confirm_auto_apply still requires explicit user confirmation. This is meaningful state-changing context. It does not, however, state whether the mode persists across sessions, who may set it, or whether the change is reversible.

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?

Front-loaded statement of purpose followed by a concise consequence clause. Two short paragraphs, each earning its place. No redundancy.

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?

Given one required enum-like parameter and an output schema that presumably returns the resulting mode, the description covers the essential behavior an agent needs. Missing only persistence/permission details and any rollback semantics. Sufficient for correct invocation.

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% and the schema documents the mode parameter with its two allowed values. The description adds conceptual meaning ('supervised' vs 'autonomous' with behavioral effects) but no format or syntax detail beyond the schema. Baseline 3 is appropriate.

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+resource (switch operation modes) and enumerates the two modes. Does not name any sibling tool to differentiate from, but no sibling performs the same function, so confusion risk is low. Clear but without explicit sibling differentiation.

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?

Implies when the switch matters by explaining what autonomous mode enables, but gives no explicit rule for when to call this tool vs simply proceeding. The conditional nature of the tool's effect is described, not its invocation context.

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