set_default_project_dir

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

Annotations indicate readOnlyHint=false (write operation) and destructiveHint=false. The description adds that confirm=true is required, implying a safety mechanism. It also specifies that the tool modifies projectDir.json. However, it does not disclose whether it overwrites values, requires permissions, or handles invalid directories.

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 extremely concise: one sentence plus a parenthetical note and a requirement. It is front-loaded with the main action and wastes no words. Every element earns its place.

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 there is no output schema, no parameter descriptions, and the tool modifies a configuration file, the description lacks completeness. It does not explain return values, error scenarios, or preconditions (e.g., existing projectDir.json). An agent would need more context for safe invocation.

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%, so the description must compensate. It adds meaning by stating confirm=true is needed, which is a constraint on the confirm parameter. However, it does not explain the 'directory' parameter format (e.g., path, relative, absolute) or the effect of confirm=false. The description is insufficient for an agent to use parameters correctly.

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 sets the default folder for new projects (projectDir.json). The verb 'Setzt' (sets) combined with the resource 'Standardordner' makes the action unambiguous. The mention of confirm=true needed distinguishes it from get_default_project_dir, though not 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?

The description provides no guidance on when to use this tool vs alternatives like get_default_project_dir. It only mentions that confirm=true is required, which is a prerequisite but not a usage guideline. No scenarios or exclusions are given.

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