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

Annotations indicate readOnlyHint=true, and the description confirms 'No auth required.' It goes beyond annotations by detailing the return structure, explaining the scaffold flag meaning placeholder data, and noting that public_url may be null for unpublished items. No contradictions with annotations.

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 richly packed but efficiently structured: purpose first, then differentiation, auth, parameters with examples, and expected return format. Every sentence adds unique value without repetition, making it both comprehensive and easy to parse.

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?

Despite having no output schema, the description fully documents the return shape and edge cases (scaffold, unpublished presentations). Combined with the thorough parameter and usage details, the tool is completely understandable without further references.

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 100%, and the description adds context beyond the schema: examples for series values ('VCN'|'ClawCamp'|'Talk'), default/max for limit and its application scope, and an explicit note about case-insensitive filtering. This fully compensates for any lack of deeper semantics.

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 'List the public archive of presentations given at Immersive Commons events...', specifying the verb and resource. It explicitly differentiates from sibling tools ic_resources_list and ic_presentations_get, making the tool's unique purpose unmistakable.

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 provides explicit guidance: when to use (listing public presentations), when not to (not for rooms, not for detail), and alternatives (ic_resources_list, ic_presentations_get). It also notes that no authentication is required and that results are grouped by series.

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