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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=false, so the safety profile is covered. The description adds the useful default-payload behavior (counts unless explicitly requested) and flags that receipt references have no download resolver, which is genuine behavioral context. It stops short of describing return shape, size, or error behavior.

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?

Three tight sentences with the core purpose front-loaded and no filler. The final sentence about legacy links versus opaque receipt references is dense and slightly cryptic, but it is short and carries information not stated elsewhere in plain prose.

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 the work of telling the agent what comes back (status, timing, outcome, counts, artifacts, receipts) and that optional detail requires flags. That is enough for a single-required-param read tool; only return format details like pagination or size limits are absent.

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%, so all five parameters including the mandatory `context` analytics field are already documented in the schema. The description restates the default-count behavior for include_logs/include_artifacts and the receipt-link semantics, but adds no syntax or constraint detail beyond what the schema provides. Baseline 3 is appropriate.

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 verb and resource ('Get a test execution') and enumerates what is retrieved: status, timing, and outcome. An agent can immediately tell this apart from write/run siblings such as run_tests or trigger_framework_run, though it does not explicitly distinguish itself from adjacent read tools like get_framework_run or k6_report.

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 describing default versus requested behavior ('Log entries and artifact paths are counted by default and returned only when explicitly requested'), which tells the agent the cheap path. However, no alternative tool is named and there is no explicit when-to-use / when-not-to-use guidance.

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