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

readOnlyHint=true already tells the agent this is a safe read, so the description's contribution is minimal. It adds the raw endpoint path, which hints at a single-record lookup, but says nothing about the returned shape, error behavior for a missing/invalid GUID, or authorization scope.

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?

Two terse sentences with no waste and the core action stated first. The terseness borders on under-specification, but nothing is padded or buried.

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?

With no output schema, the description carries responsibility for at least sketching what a fetched account record contains, and it does not. For a one-parameter read tool this is a significant omission, leaving the agent to guess at the payload.

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 coverage is 100% and the single `id` parameter is fully documented in the schema, including UUID format and the note that it comes from a preceding read. The description adds no parameter meaning beyond that, so the baseline 3 applies.

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 pairs a generic verb ("Read") with an ambiguous object ("the selected record"), which only becomes concrete through the REST path GET /v1/accounts/{id}. The resource is inferable from the endpoint and the title, but the description itself never says "account" and never distinguishes this from siblings like servicemonster_get_account_profile.

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 when-to-use guidance is given, and nothing distinguishes this single-account fetch from servicemonster_get_account_profile or the list_accounts variant. The only implicit signal is the {id} path parameter, which the agent must decode itself.

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