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

Annotations declare readOnlyHint=false, idempotentHint=true and destructiveHint=false, and the description adds genuinely useful material beyond them: the hard operating limits (bounded signal processing, 8 channels, 4096 samples/channel). However it never explains the non-read-only nature of the call, cost implications of max_total_price, or idempotency-key behavior, so it leaves behavior partially undisclosed.

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?

The Problem/Input/Result/Limits layout is compact and front-loads the purpose, but the truncated '....' and run-on field list make it read like clipped boilerplate rather than a deliberately structured description.

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?

An output schema exists, so return values need not be restated, and the description does cover problem, inputs, result and operating limits. Still missing are the cost/pricing model, idempotency semantics, and whether this is a synchronous call or a job submission, which matters for a mutation-flagged tool in a job-oriented sibling set.

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 request object is opaque (free-form additionalProperties), so the description's enumeration of request internals (operations, fixture, objective, maximum operations, maximum equivalence) is real added value. But the three other required top-level parameters (schema_version, idempotency_key, max_total_price) are never explained, and the trailing '....' suggests the list is truncated.

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 ('Optimize this supported Wave pipeline') plus the optimization target ('operation-count objective and equivalence rule'), and it lists what comes in and out. It distinguishes itself loosely from verification siblings like wave_verify_wave_pipeline_v1 by framing itself as optimization, though it never names the alternative explicitly.

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 guidance, no prerequisites, and no mention of alternatives such as wave_verify_wave_pipeline_v1 or run_wave_job. The 'supported Wave pipeline' phrasing implies a precondition but never states it, leaving selection entirely to inference.

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