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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is fully covered by structured data. The description adds the useful fact that the set is a fixed catalog tied to a specific decision context, but says nothing about media formats, hosting, or whether anything is returned for a missing asset.

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 sentences, front-loaded with the asset list and closed with the usage condition; every clause earns its place. The enumeration is long but each item is distinct content, not filler.

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, the description compensates by enumerating the actual return contents (videos, gallery, speakers, recap, page, PDFs), which is precisely what an agent needs to judge relevance. For a zero-required-parameter read tool, nothing material is missing.

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?

There is only one optional parameter and schema description coverage is 100%, so the schema already explains 'context' fully. The description adds no parameter-level meaning, which matches the baseline 3 when the schema carries the burden.

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 names a concrete resource (YouTube videos, photo gallery, recap material, the partner page, and two PDFs) scoped to an ELC Conference 2027 partnership decision, so an agent knows exactly what it retrieves. It is distinguishable from siblings like get_partnership_guide or get_audience_and_proof, though the boundary between this catalog and those proof/guide tools is never drawn explicitly.

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?

"Use when someone needs material to show internally" gives one usable trigger condition, which is more than nothing. However it offers no exclusions and never references the sibling tools that also return conference material (get_audience_and_proof, get_conference-info), leaving the agent to guess which one to pick.

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