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

Adds substantial behavior beyond the annotations: what the response contains, the one-time nature of the file link, expiry, the fact that repeated calls replay already-picked-up content marked with its first pickup time, and the important constraint that it never grants permissions. However, the annotations declare readOnlyHint=false while the description frames this purely as retrieval, and it never explains what state changes (if any) when content is picked up.

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?

Purpose and trigger are front-loaded in the first two sentences, which is the right ordering. The tail is long and runs into display/presentation rules ('show it exactly as received ... anything of your own goes after it, marked as yours') that are useful but make the definition dense and semi-colon heavy.

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 carries the return-value burden and does it reasonably: it names the payload (items, full document text, download link) and the expiry/replay semantics. What is missing is the shape of the returned payload and what happens when nothing has ever been sent, so an agent still has to discover the response structure empirically.

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 input schema has zero parameters, so the baseline is 4; there is no parameter meaning to add, and the description correctly implies a no-argument call by describing call-time conditions instead of inputs.

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 ('pick up context ... sent from another of their AI apps through Oyeh') and enumerates what comes back: items and a document's full text, plus a one-time download link. It is clearly distinct from the sending side (send_context), but it never names a sibling, so the boundary with context_status or take_back_context is left to inference.

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?

Gives concrete trigger conditions: 'Call it when your person asks, or after they say yes when an answer shows context_waiting,' and clarifies that repeat calls are legitimate because already-picked-up content is returned until it expires. It does not say when NOT to call it or point at context_status/take_back_context as alternatives, so the routing is implied rather than explicit.

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