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

Annotations already cover readOnly, idempotent, non-destructive and closed-world; the description adds the meaningful separate point that 'Nothing is stored', which clarifies persistence rather than mere read-safety. Because there is no output schema, the description also carries the return-value burden, and it does say what comes back. It doesn't cover edge cases such as invalid or incomplete answer sets.

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?

One tightly packed sentence with the action, the input provenance, and the return contents front-loaded; every clause earns its place and nothing is repeated.

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 single-parameter, read-only tool with no output schema, the description supplies what the agent needs: input shape, upstream tool, return contents, and the no-storage guarantee. Minor gap on behavior with malformed answer sets.

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 schema parameter description already states '9 answer letters, a to d, one per question in the order of get_pm_title_fit_questions, as a list or as one string.' The tool description essentially restates this, adding the count and provenance but no new syntax or format details. 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?

States a specific verb (scores) and resource (the 9 title fit answers), then names the exact output (closest title among PM, PgM, TPgM plus what hiring managers look for). It explicitly distinguishes itself from the sibling get_pm_title_fit_questions as the scoring counterpart to that tool.

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 dependency is spelled out: answers must be 'as returned by get_pm_title_fit_questions', so an agent knows this is the second step after fetching the questions. No explicit exclusions or when-not-to-use guidance is given, but for a single-purpose scorer the context is clear.

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