Zephyr: Get Test Cycle Links

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is clear. The description adds that the tool returns issues, web links, and test plans, which provides behavioral context beyond annotations. However, it lacks details on response format, pagination, or error handling, which would enhance 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 a clear header, parameter list, and examples. It is concise and front-loaded with the core purpose. Minor redundancy in the examples (both have same expected output) could be trimmed, but overall it's efficient.

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 presence of an output schema (indicated) and annotations, the description sufficiently covers the tool's functionality. It specifies the types of links returned. However, it does not discuss edge cases like non-existent cycles or limits, but for a simple retrieval tool this is acceptable.

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 100% coverage with a description for the sole parameter. The description includes two detailed examples with sample inputs and expected outputs, which clarifies parameter usage beyond the schema. This adds meaningful value, earning a score above the baseline of 3.

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 starts with a clear verb 'Get' and specifies the exact resource 'all links (issues, web links, and test plans) associated with a test cycle'. This immediately distinguishes it from sibling tools like zephyr_get_test_cycle (gets cycle details) and zephyr_get_test_case_links (links for test cases).

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 implies usage when you need the links of a specific test cycle, but it does not explicitly state when to use this tool versus alternatives (e.g., zephyr_get_test_cycle for cycle metadata, qtm4j_get_linked_requirements_for_test_cycle for requirements). No guidance on when not to use it or prerequisites is provided.

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