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

With no annotations, the description carries the full behavioral burden. It usefully discloses that this is a PUBLIC READ and that the cell must be accepted, but it does not explain failure behavior, permissions, rate limits, or what happens if the cell is not accepted.

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 definition is a single compact sentence with the key access mode front-loaded in brackets. The abbreviation 'summary (w)' is slightly cryptic, but there is no wasted verbiage.

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?

This is a simple two-parameter read with full schema coverage, so the core is adequate. However, with no output schema, the description should clarify what the returned 'summary (w)' actually is and whether any post-acceptance state is required.

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 description coverage is 100%, so the schema already documents both 'id' and 'folder'. The description adds only the 'accepted cell' constraint and sidecar context, not parameter-specific format or syntax beyond the schema.

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 states a specific verb+resource: retrieving the summary of an accepted cell from the sidecar database. It is clearer than the bare name 'load', but it does not explicitly distinguish this from sibling read tools like get_knowledge_item or read_map_links.

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?

It gives no when-to-use guidance, no exclusions, and no named alternatives. The phrase 'accepted cell' implies a precondition but does not explain how or when an agent should choose this over related tools.

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