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

Annotations already establish the safety profile (non-readonly, non-destructive, non-idempotent, closed-world), so the bar is lower. The description adds genuine context beyond them: a two-step draft/commit flow via confirm:true and the system-set createdBy=manual attribute. It omits permission requirements and failure behavior, keeping it from a 5.

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?

Three compact fragments, zero filler, with the core action and the commit mechanism front-loaded. Every clause carries information the schema does not.

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?

For a simple 4-param create tool with no output schema, the description is adequate but leaves loose ends: what farmId identifies, what state the note is in without confirm:true, and how it relates to list_farm_notes. A little more detail would make the write flow unambiguous.

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 0%, so the description must carry the load. It clarifies the expected date format (YYYY-MM-DD) and the commit role of confirm, but leaves farmId and content semantics to inference, so it only partially compensates for the gap.

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 ('Create') and resource ('Farm Note'), making it distinguishable from update_farm_note, delete_farm_note, and get_farm_note by name alone. It does not explicitly contrast itself with those siblings, so it falls short of a 5.

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?

No statement of when to use this versus update_farm_note or the other note tools, and no prerequisites or exclusions. The only usage-adjacent detail is the confirm:true commit gate, which is behavioral rather than routing guidance.

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