add_training_note

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

No annotations are supplied, so the description carries the full behavioral burden. 'Adds an entry' hints at append semantics, but it does not say what happens if a note already exists for that date, whether existing content is overwritten or merged, or whether any permissions are needed for this mutation. Return values are covered by the output schema, so that omission is acceptable.

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?

A single sentence with zero waste; the action is front-loaded and the parameter hint follows in parentheses. Nothing is redundant or padded.

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 two-parameter tool with an output schema, the definition covers the essential call mechanics: what it does and how to format the optional date. The remaining gap is behavioral detail about same-date collisions, which is a modest omission for a straightforward note-append tool.

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 compensate. It does well for 'date' by giving the YYYY-MM-DD format and the today-by-default behavior, which the schema only expresses as a null default. The required 'text' parameter gets no explanation of expected content, length, or formatting, leaving half the parameters undocumented.

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 and resource: it adds an entry to the training notes. That is clearly distinct from the sibling read_training_notes, though the description never names that sibling 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?

The write-oriented purpose implies when to use it (recording a note rather than reading notes), but there is no explicit when-to-use or when-not-to-use guidance and no mention of read_training_notes as the counterpart for retrieval.

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