devcontainer_configure

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 says 'Configure' which implies a mutation, but it does not explain side effects (e.g., overwriting devcontainer.json, applying secrets, starting services), whether changes are reversible, authentication requirements beyond a vague API key parameter, or any pro-plan restrictions beyond the ambiguous '(Pro)' marker.

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 one concise sentence, but the parenthetical '(Pro)' consumes space without explaining what 'Pro' requires. The core content is front-loaded and efficient.

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 tool with 4 optional parameters and 100% schema coverage, the description is mostly adequate. It lacks: what 'advanced' implies, whether files are generated/updated in place, any relationship to devcontainer_generate's output, and why the API key is required. However, the parameter schema compensates for configurability details.

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 explains each parameter (volumes, env_files, compose_services). The description adds a high-level semantic framing: these parameters relate to 'Docker Compose, networking, and secrets', which helps an agent map the parameters to the intended feature areas.

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 states a clear verb ('Configure') and resource ('advanced devcontainer features'), and lists specific feature areas (Docker Compose, networking, secrets). It is distinguishable from sibling tools like devcontainer_generate or devcontainer_add_extensions, though it doesn't explicitly contrast itself with 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?

The description implies usage for advanced devcontainer configuration but provides no explicit guidance on when to use this tool vs devcontainer_generate, devcontainer_add_extensions, or other configuration tools. The '(Pro)' suffix hints at availability/pricing but not usage context.

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