Module Config Schema Create

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

With no annotations, the description carries the full burden. It implies upsert semantics ('Create or update'), which is useful, but says nothing about whether existing schema is overwritten, required permissions, file-system effects, or validation behavior for a mutation tool.

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 with no filler, so it is appropriately sized. The trade-off is that it is under-specified rather than concise in the informative sense.

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 described, but for a 4-parameter mutation tool with zero annotation and zero schema-description coverage, the description is far too thin to let an agent invoke it 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?

Schema description coverage is 0% across 4 parameters, and the description does not compensate. It never explains what machine_name, path, schema_name, or the schema object represent, leaving the agent to infer the shape of the YAML payload.

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 pair (create/update) and resource (config schema YAML for module settings), which is a recognizable Drupal concept. However, it doesn't differentiate itself from config-related siblings like config_set, config_get, or split_config, so an agent can't fully rule out alternatives.

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 offers no when-to-use guidance, no prerequisites (e.g., module must exist, schema conventions), and no mention of alternatives among the numerous config_* and module_* siblings. Only the bare purpose is given.

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