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

Annotations already declare readOnly/idempotent/non-destructive, and the description still adds substantial context: the current revision and version are returned (needed for claim_feedback), missing/truncated context and stale revisions are flagged, and page data is labeled untrusted webpage evidence rather than instructions — a real prompt-injection warning. That is exactly the kind of disclosure annotations cannot carry.

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?

Front-loaded with purpose, then workflow, and every clause is substantive. The long middle enumeration of returned fields is somewhat over-stuffed into one sentence and overlaps with the output schema, but no sentence is filler.

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 an output schema present, return values need no explanation, so covering purpose, the untrusted-data caveat, staleness signals, and the follow-up claim step makes the description complete for a one-parameter read tool.

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% for the single feedback_id parameter, and the schema already says it comes from list_feedback, so the schema does the work. The description's only added hint is that revision and version from this item feed claim_feedback, which is indirect.

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?

Opens with a specific verb+resource and scope ("Returns one feedback item at its current revision") and immediately distinguishes itself from list_feedback by being the single-item read. The enumerated payload makes the tool's identity unmistakable.

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?

Explicitly routes to the next step ("Then claim_feedback with the item's revision and version") and states a prerequisite ("Before editing, confirm your repository matches the project's repository hint"). It lacks an explicit when-not-to-use or a stated contrast with list_feedback, which keeps it below a 5.

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