delimit_repo_config_validate

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

With no annotations, the description discloses side effects (read-only), remote handling (shallow clone to tempdir), and the internal backend call. Missing details about prerequisites or failure behavior, but the output schema likely covers return values. Overall good transparency.

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 well-structured with sections, no redundant sentences, and front-loaded with the core purpose. Every sentence contributes value, and it is concise given the information conveyed.

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 single parameter (fully described) and output schema, the description covers usage, side effects, and sibling differentiation. Minor gaps: no mention of experimental status's implications or potential error cases, but overall complete for a validation tool.

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 describes the 'target' parameter with 100% coverage. The description adds context about accepting local path, 'owner/repo', or GitHub URL, but this mirrors the schema. No significant new meaning added beyond schema.

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 'Validate repository configuration files' and specifies structural validity checks. It distinguishes from siblings by contrasting with delimit_repo_config_audit (policy compliance) and delimit_repo_analyze (full analysis).

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?

Explicitly provides 'When to use' (pre-merge check) and 'When NOT to use' with alternative tools (delimit_repo_config_audit and delimit_repo_analyze). Also includes a sibling contrast sentence.

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