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

No annotations are provided, so the description carries full burden. It states this is a read operation ('Get'), which implies non-destructive behavior, but doesn't disclose any behavioral traits such as permissions needed, rate limits, response format, or whether it returns cached/live data. The description adds minimal context beyond the basic operation, leaving significant gaps for a tool with no annotation coverage.

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?

The description is a single, efficient sentence that front-loads the core action ('Get current presentation configuration') and adds clarifying details in parentheses. Every word earns its place, with zero waste or redundancy. It's appropriately sized for a simple, parameter-less 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?

Given the tool's simplicity (0 parameters, no annotations, no output schema), the description is adequate as a minimum viable explanation. It covers what the tool does but lacks details on behavioral context, usage guidelines, and output format. For a read-only config tool, this is passable but leaves room for improvement in guiding the agent effectively.

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?

The tool has 0 parameters, and schema description coverage is 100% (since there are no parameters to describe). With no parameters, the baseline is 4, as there's nothing for the description to compensate for. The description doesn't need to add param semantics, and it appropriately focuses on the tool's purpose instead.

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?

The description clearly states the verb ('Get') and resource ('current presentation configuration'), with specific details about what configuration includes ('colors, fonts, instructor info'). It distinguishes from siblings like 'get_template' (templates vs. current config) and 'update_instructor' (read vs. write), though not explicitly named. Purpose is specific but sibling differentiation is implicit rather than explicit.

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 guidance is provided on when to use this tool versus alternatives. The description implies it retrieves current configuration, but it doesn't specify contexts like after setup, before generation, or compared to 'get_template' for templates or 'list_presentations' for presentation lists. Usage is inferred from the purpose alone, with no explicit when/when-not statements.

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