get_personal_records

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

With no annotations, the description must carry the behavioral burden. It clearly indicates a read operation and that filtering is optional, but it does not disclose output format, pagination, ordering, or error behavior. This is acceptable but not rich.

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, front-loaded sentence conveys the action, resource, and optionality without wasted words. The parenthetical expansion of 'PRs' adds clarity without bloat.

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 tool with one optional parameter and no output schema, the description is sufficient to invoke correctly: it explains what is returned and when the filter applies. It could add return-shape details, but none are strictly required for correct use.

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 exerciseId parameter is already described as 'Exercise definition ID to filter by.' The description's 'filtered by exercise' adds no meaningful detail beyond the schema, so it sits at the baseline.

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 names a specific verb ('Get') and a distinct resource ('personal records') and clarifies the optional exercise filter. No sibling tool targets personal records, so the tool is unambiguously distinguishable from the rest of the API.

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 phrase 'optionally filtered by exercise' gives clear context: call this when retrieving PRs, with or without an exercise restriction. It does not mention exclusions or alternatives, but none are needed given no similar sibling tool.

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