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

Annotations already cover readOnly/idempotent/non-destructive, so the bar is lower, but the description adds real value: a hard cap of 50 rows and the pagination rule to reuse an unchanged cursor with the same limit. The caveat about what the records do NOT represent is also useful disambiguation.

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 tight sentences, front-loaded with the core action, then scope caveat, then pagination. No filler; every sentence earns its place.

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?

An output schema exists, so return values need not be explained, and annotations carry the safety profile. The description covers scope boundaries and pagination adequately; only the limit default/range and cursor format remain unaddressed.

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 touches the limit ('at most 50 rows') and cursor ('reuse an unchanged cursor with the same limit'), but omits the default of 25, the 1-50 bounds, and the cursor format, leaving gaps the schema does not fill.

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 (Read) and resource (saved manual monitoring records, with entered amount and entry APY), and sharpens scope by saying these records do not establish balances, current value or realised earnings. That negative scoping helps distinguish it from valuation-oriented siblings, though no sibling is named 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?

Usage is implied by 'your saved manual monitoring records' and the exclusion of balance/current-value data, which hints at the right context. However, it never says when to prefer this over sibling list tools (list_wallets, list_notebook_entries) or what prerequisites exist.

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