note_get

Fetch a single note by its unique ID to test object-level authorization. Use this tool to identify BOLA/IDOR vulnerabilities in multi-tenant applications.

Instructions

Get one note by id.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

TDQS

C2.4/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'Get one note by id' and does not mention whether the operation is read-only, what permissions or token scopes are required, whether errors are thrown for missing notes, or what the response contains.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and front-loaded with the core action, which is good. However, it is under-specified even as a minimal viable definition; a single terse sentence does not provide enough surrounding structure or context to be genuinely helpful.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with no annotations, no output schema, and two required parameters that are completely undocumented, the description is not complete enough. It fails to explain token usage, return values, error behavior, or how this tool differs from its many similarly named siblings.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

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 for the undocumented parameters. It does not mention 'token' at all and only indirectly implies 'id' through 'by id.' The agent receives no added meaning about token purpose, id format, or relationships between the parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb ('Get'), the resource ('one note'), and the selection criterion ('by id'). This distinguishes it from tools like note_list and note_batch_get, though it does not explicitly name those alternatives.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no guidance on when to use this tool versus closely related siblings such as note_get_by_query, note_get_scoped, note_batch_get, or note_search. The intended use is only implicitly 'when you need a single note by its id,' but no exclusions or alternatives are stated.

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