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

Annotations already declare destructiveHint=true, idempotentHint=false and readOnlyHint=false, so the safety profile is covered and "Remove" merely restates it. The description adds no extra context such as whether the deletion is permanent, what happens if the file name doesn't exist, or whether other files are affected — which is the kind of detail that would raise this above baseline.

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 with zero wasted words. It is efficient, though its brevity borders on under-specification rather than optimal conciseness.

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?

For a simple two-required-parameter destructive tool, the definition plus annotations cover the essentials. However, a mutation tool with no output schema should say something about confirmation, missing-file behavior, or irreversibility, none of which appear here.

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 both testId and name documented inline, so the baseline is 3. The description adds nothing about name matching semantics (exact vs case-sensitive), but it isn't required to given full schema coverage.

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 ("Remove") and a scoped resource ("one of a test's files"), which distinguishes it from delete_test (whole test) and add_test_file (the inverse operation). It falls short of 5 only because it doesn't explicitly name the boundary against those siblings.

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?

No when-to-use or when-not-to-use guidance, no mention of prerequisites (e.g., whether the test must not be running), and no alternatives named. The agent must infer that this is the per-file deletion counterpart to delete_test and add_test_file.

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