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

No annotations are provided, so the description carries the full burden. It discloses that the operation is a mutation that can record optional agent traceability, but says nothing about whether an existing baseline is overwritten, whether the action is reversible, or what permissions are required.

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 short sentences, front-loaded with the core action and effect, with no wasted words. It is well sized for what it chooses to say.

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 14-parameter mutation with a nested traceability object, no annotations, and no output schema, this description is far too thin. It omits baseline-replacement semantics and essentially all parameter meaning, so an agent could invoke it but not confidently.

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?

With 14 parameters and 0% schema description coverage, the description must compensate and does not. It only alludes to the traceability fields ('agent traceability'), leaving runId, envClass, and the ten-plus traceability parameters undocumented beyond their names.

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 (promote) plus resource (a performance run) and its effect (becomes the baseline for an environment class), which is enough to separate it from siblings like compare-perf-to-baseline, get-perf-run, and list-perf-baselines. No sibling is named explicitly, so it stops short of 5.

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 when-to-use or when-not-to-use guidance and no mention of alternatives such as compare-perf-to-baseline. The purpose implies its use case but nothing tells the agent under what conditions selecting a baseline is appropriate.

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