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

Annotations already declare readOnlyHint, idempotentHint, and closed-world, so the safety profile is covered. Beyond that, the description adds genuine value: results are returned 'in order', each entry carries the target element and page path, and only the reporter's actions are included. It stops short of explaining result count, truncation, or how pagination via the cursor behaves.

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 tight sentence with zero filler, and the most decision-relevant content (what the data is) comes first. The fragmentary, verbless construction costs a small amount of clarity but wastes no reader attention.

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 only three parameters, full schema coverage, and no output schema, the description carries the burden of describing return content and does so adequately by naming the event types, their ordering, and their payload fields. Missing pieces are secondary: no mention of pagination semantics or result limits, and no guidance on how this differs from the other replay-inspection tools.

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%, with recording, limit, and cursor all documented in-schema including the share-link-or-id format. The description adds no parameter-level detail, 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?

The description names a specific resource — clicks, inputs and navigations captured during a recording — plus two concrete fields per entry (target element, page path) and an ordering guarantee. It implicitly distinguishes itself from the log/network/frame siblings by naming interaction data, though it is written as a noun phrase with no verb such as 'List' or 'Get'.

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?

There is no explicit when-to-use, when-not-to-use, or alternative routing. The phrase 'the reporter performed' narrows the scope to one user, which hints at a replay-investigation use case, but with seven sibling tools the agent gets no help deciding between this and get_console_logs, get_network_requests, or get_frames.

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