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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the bar is lower. The description adds genuinely useful context beyond that: newest-first ordering, the exact status vocabulary (received/planned/fixed/shipped/declined/duplicate), and that replies are attached to each item. It omits pagination behavior, which keeps it from a 5.

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 that leads with the verb and resource, with zero filler. The mid-sentence parenthetical about unowned AIs breaks the flow slightly, but every clause conveys distinct information (scope, sort order, return fields).

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 steps in to describe the returned shape (per-item status plus any reply), which is exactly what an agent needs. For a one-param, read-only list tool, nothing material is missing.

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?

Only one optional parameter (limit) and schema description coverage is 100%, so the schema already carries the semantics. The description adds nothing about the limit's behavior (default, cap, or paging), 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?

States a specific verb (List) and a precisely scoped resource: reports/feedback/ideas *sent* by the user and their AIs, or by an unowned AI. Sibling tools like get_feedback (single item) and send_feedback are implicitly distinguished by the 'sent' scope. Sorting (newest first) and returned fields (status, reply) are included in the same sentence.

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?

Usage is implied by the 'sent' framing and the ownership clause, but the description never explicitly says when to use this versus get_feedback or send_feedback. No exclusions or prerequisites are stated, so the agent must infer that this is the enumeration counterpart to the retrieval tool.

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