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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds genuine behavioral context beyond that: what the queue contains (install-based sandbox tests/retests) and what accompanies each entry (reason and date added). It does not mention pagination or result limits.

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?

Two sentences with no filler; the core scope is front-loaded and the second sentence adds usable intent. Slightly more than minimal, but every clause carries information.

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 does reasonably well describing what entries contain (reason, date added). However, it omits any explanation of the status filter, which is the only knob an agent can turn, leaving an incompleteness for a tool whose sole parameter is undocumented.

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 0%, and the description never mentions the single 'status' parameter at all. The enum values 'open' vs 'all' and the 'open' default are left entirely unexplained, so the description fails to compensate for the schema gap on a filter that materially changes the result set.

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 and resource ('List the tools in Agent Tested's public lab queue') and narrows scope to tools awaiting install-based sandbox tests or retests. It is clearly distinct in kind from siblings like get_tool or search_tools, though it does not explicitly name a sibling to differentiate against.

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?

Gives clear positive context for when to use it ('see what is being tested next or to pick a tool for a field report'), which implicitly routes the agent to submit_field_report for the latter case. No explicit exclusions or when-not conditions are stated.

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