analyze_repository_patterns

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool is for reading and analyzing, implying a read-only operation, but does not specify if it modifies files, requires specific permissions, handles errors, or provides output details, leaving significant gaps in understanding its behavior.

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, efficient sentence that directly states the tool's purpose without unnecessary words. It is front-loaded with the core action, though it could be slightly more structured by separating key points for clarity.

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 complexity of analyzing repository patterns with no annotations and no output schema, the description is incomplete. It fails to explain what the analysis entails, what output to expect, or how it interacts with sibling tools, making it inadequate for guiding effective use.

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 description coverage is 100%, so the input schema already documents both parameters ('repo_path' and 'pattern_types') with descriptions and defaults. The description adds no additional meaning beyond the schema, such as explaining what 'pattern_types' entail or how analysis is performed, meeting the baseline for high coverage.

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 action ('Read and analyze') and resource ('repository') with specific targets ('existing patterns, formats, and validation rules'), making the purpose evident. However, it does not explicitly differentiate from sibling tools like 'review_and_enhance_code', which might also involve repository analysis, leaving room for ambiguity.

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?

No guidance is provided on when to use this tool versus alternatives. The description lacks context on prerequisites, such as needing a valid repository path, and does not mention sibling tools like 'review_and_enhance_code' for comparison, leaving usage unclear.

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