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. 'Get' implies a read-only operation, but the description doesn't specify whether this requires authentication, what the return format looks like, whether there are rate limits, or what happens if the batch doesn't exist. For a tool with zero annotation coverage, this minimal description leaves critical behavioral aspects undocumented.

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 extremely concise (5 words) but borders on under-specification rather than effective conciseness. While it's front-loaded with the core action, it lacks the necessary detail to be genuinely helpful. The single sentence structure is simple but incomplete.

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 implied by 'synthetics_ci_batch' (likely involving CI/CD synthetic testing batches), the description is inadequate. With no annotations, no output schema, and a minimal description, an agent cannot understand what this tool actually returns or how to use it effectively. The description should explain what constitutes a 'batch' and what 'updated details' include.

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 tool has 0 parameters with 100% schema description coverage, so the schema already fully documents the parameter situation. The description doesn't need to compensate for any parameter gaps. A baseline of 4 is appropriate since there are no parameters to explain, though the description could theoretically mention that no parameters are required.

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 'Get a batch's updated details' is vague and tautological - it essentially restates the tool name 'get_synthetics_ci_batch' without specifying what a 'batch' is or what 'updated details' include. While it indicates a retrieval operation, it lacks specificity about the resource domain (synthetics CI) and doesn't distinguish this tool from other get_* tools in the sibling list.

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 zero guidance on when to use this tool versus alternatives. There are numerous other get_* tools in the sibling list (including get_synthetics_test_results_v1, get_synthetics_tests, etc.), but no indication of when this specific batch retrieval tool is appropriate versus other synthetics-related retrieval tools.

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