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

With no annotations, the description carries the full burden and does disclose one important behavioral trait: cross-account access is rejected, implying an authorization boundary. It says nothing about whether the memory must be published vs. draft, what error behavior looks like, or what 'details' includes, so significant transparency gaps remain.

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 short sentences with the core purpose front-loaded and the access constraint second — nothing wasted. It is arguably too terse for the information an agent needs, but there is no filler or 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?

A simple single-parameter read tool with no output schema, so the description needn't explain return values. However, with no annotations and no schema descriptions, the definition leaves the agent without guidance on where memory_id comes from or what happens on a rejected cross-account request.

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 0% and the single memory_id parameter is an undocumented string. The description adds only indirect meaning by implying the ID must refer to a memory owned by the connected account; it gives no format, example, or sourcing guidance (e.g., obtain from get_my_memories).

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 gives a specific verb and resource ('Get details of one memory'), which is clearly distinct from the listing sibling get_my_memories and the mutation siblings like publish_memory. It stops short of naming any sibling explicitly, so an agent must infer the distinction from the singular 'one memory' phrasing.

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?

Usage context is implied by 'owned by the connected account' and 'Cross-account access is rejected', which tells the agent this only works for its own memories. There is no explicit statement of when to prefer this over get_my_memories or search, and no prerequisite guidance beyond the ownership constraint.

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