devcontainer_generate

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

No annotations are provided, so the description carries the full burden of behavioral disclosure, and it barely does. It does not state whether the tool writes a file to disk, returns the generated config, requires the api_key for every call, or what happens to an existing devcontainer.json.

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 containing only the verb, resource, and purpose. Every word earns its place with zero fluff.

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 annotations and no output schema, the description must explain output and behavior, but it stops at 'generate a configuration'. It omits what happens to the result, how parameters interact, and why an api_key is involved, leaving an agent to guess the call's effects.

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 the schema already documents all five parameters and the base_image enum; the description adds no parameter-level meaning. The baseline of 3 applies because the schema carries the load, though its descriptions are thin (e.g., node_version's relationship to base_image is left unexplained).

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 (generate) and resource (devcontainer.json configuration), plus the purpose of a consistent development environment. It is clearly distinct from sibling tools like devcontainer_add_extensions and devcontainer_configure in the generate-vs-modify sense, though it does not explicitly name them.

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: call this when you need a devcontainer.json created. But the description gives no explicit when/when-not guidance, no alternatives, and no prerequisites such as whether an existing configuration would be overwritten.

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