index_repository

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It mentions 'verbose terminal debugging logs' which hints at output verbosity, but does not clarify if indexing is destructive, idempotent, or requires network access. Important traits like side effects or safety constraints are omitted.

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 sentence, highly concise and front-loaded with the main action. However, it is so brief that it sacrifices necessary details, which slightly reduces effectiveness. It earns full marks for structure but not for completeness.

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 the tool's simplicity (one parameter, no nested objects) and the existence of an output schema, the description should still cover parameter semantics and usage context. The lack of parameter explanation and usage guidance makes it incomplete for an agent to use reliably.

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?

The input schema has 0% description coverage (no parameter descriptions), yet the tool description does not compensate by explaining the 'repo_path' parameter. The agent is left without any guidance on what constitutes a valid path (e.g., absolute vs relative, local vs remote), making correct invocation difficult.

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 verb 'indexes' and the resource 'repository folder', making the primary action obvious. It includes an extra behavioral detail about verbose logs. However, it does not explicitly differentiate from sibling tools like 'search_codebase' or 'list_indexed_repositories' beyond the verb, but the verb itself is distinct enough.

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 versus alternatives such as 'search_codebase' or 'delete_repository'. It does not mention prerequisites, expected context, or conditions under which indexing is appropriate, leaving the agent to infer usage without support.

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