buildx_bake

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

The description discloses the return format (dict with returncode, stdout, stderr, truncated) and lists parameters with explanations. While annotations have no destructiveHint, the description correctly implies non-destructive behavior (build operation). It adds behavioral context beyond annotations, though side effects like local image creation are not explicitly stated.

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 description is well-structured with a clear purpose statement, parameter list in arg-style, and return type. It is slightly lengthy but each sentence adds value. The parameter explanations are concise and informative.

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?

Given 10 parameters, no output schema, and sparse annotations, the description covers parameters and return format adequately but lacks details on how targets and files interact, or how compose-specific behaviors work. Some gaps remain for a tool with this complexity.

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 0% schema description coverage, the description provides meaningful explanations for all 10 parameters, including defaults and usage (e.g., 'Bake targets to build (default: the `default` group)'). This compensates for the lack of schema descriptions.

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 clearly states the tool builds multiple targets defined in a bake file, specifying support for HCL, JSON, or compose formats. This distinguishes it from sibling tools like buildx_build (single build) and compose_build (single compose service).

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?

The description implies usage for multi-target builds using bake files but does not explicitly state when to use this tool over alternatives like buildx_build or compose_build. No exclusion criteria or when-not-to-use guidance is provided.

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