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

Beyond the annotations, the description discloses substantial behavior: ordering by episode publication date, preserving hedges, showing both older and newer positions, and never judging. This gives the agent a strong mental model of what the tool will return and how it handles temporal inconsistencies.

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?

The purpose is front-loaded and every sentence contributes behavioral value. Minor redundancy exists in mentioning 'episode publication date' twice and in the illustrative 2023 example, which could be tightened without losing meaning.

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 adequately explains what the agent can expect: attributed and dated positions in chronological order, including both reversals and re-assertions. No critical calling information is missing, and the two-parameter schema is fully covered.

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 100%, so the baseline is 3. The description mostly restates the schema's person identity constraint and the optional debate narrowing, adding no deeper parameter semantics such as value formats or edge cases.

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 states exactly what the tool does: it traces one speaker's positions over time, ordered by episode publication date and optionally filtered to one debate. It also distinguishes itself from siblings by emphasizing chronological evolution, reversals, and non-judgmental presentation.

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 description clearly conveys when to use this tool: when an agent needs a chronological view of a single person's views, including these reversals or re-assertions. It does not explicitly name alternative sibling tools or exclusion conditions, so it falls just short of full routing guidance.

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