Summarize Directory

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

Annotations already indicate readOnlyHint=true and destructiveHint=false. The description adds valuable context beyond annotations by stating that tool 'samples' the tree and identifies 'dominant file types' and 'likely entry files', implying a heuristic or sampling approach. No contradictions with annotations.

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 a single, front-loaded sentence that efficiently conveys the core purpose. However, it could be slightly more structured (e.g., listing key aspects) without increasing length.

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 no output schema and 6 parameters, the description provides adequate high-level context but lacks detail on parameter behavior and return values. Annotations cover safety and idempotency, but the description does not fully compensate for the missing schema descriptions.

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 schema description coverage at 0%, the description must compensate by explaining parameters, but it does not mention any of the six parameters (e.g., recursive, max_entries, output_format). The description's mention of 'sampling' and 'entry files' hint at output_format but falls short of providing meaningful parameter semantics.

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 uses the specific verb 'Summarize' with the resource 'a repository directory' and lists key outputs (tree structure, dominant file types, likely entry files). This clearly distinguishes it from sibling tools like gitlab_list_repository_tree (which lists entries without summarization) and gitlab_get_file (which reads file contents).

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 obtaining a high-level summary of a directory, but it does not explicitly state when to use this tool versus alternatives (e.g., gitlab_list_repository_tree for full listing, gitlab_get_file for specific files). No exclusion criteria or prerequisites are mentioned.

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