repo_summarize_repository

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

With no annotations provided, the description bears full responsibility for disclosing behavioral traits. It only mentions that the summary is 'concise' and 'high-level', which gives minimal insight into output scope. It does not disclose whether the tool reads files, depends on prior indexing, has side effects, or requires permissions. The lack of safety or limitation information makes this insufficient.

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, focused sentence that immediately states the tool's purpose. There is no redundant information, making it appropriately concise and well-structured.

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?

The tool is simple with one parameter and no output schema, but the description lacks essential context for an agent to use it effectively. It does not explain what the summary contains, how it is generated, or when to prefer it over sibling tools. This is inadequate given the crowded repo_* toolset and absence of usage guidance.

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 schema already provides a clear description for the single 'path' parameter ('Absolute path to the repository root directory'), covering 100% of parameters. The tool description does not add extra parameter semantics beyond what the schema provides, so the baseline of 3 applies.

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's action: 'Get a concise high-level technical summary of the repository.' This specifies the verb ('Get') and resource ('technical summary of the repository'), making the purpose clear. However, it does not differentiate from sibling tools like 'repo_explain_project' or 'repo_explain_architecture', which could also provide summaries, so it lacks sibling differentiation.

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. There is no mention of specific scenarios, prerequisites, or exclusions. Sibling tools like 'repo_analyze_repository' and 'repo_explain_project' are not referenced, leaving the agent without direction on selection.

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