Bulk Update Test Manager Test Case Instances

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

The description discloses critical behavioral traits: including status resets all steps to 'Skipped', environment_id and remarks are silently ignored, and that the action is real and persistent. No annotations are provided, so the description fully bears this burden.

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 long but each sentence adds value. It is front-loaded with purpose and usage, then covers constraints and dangers. Minor redundancy in the danger warning could be tightened, but overall 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?

For a complex tool with no output schema and nested objects, the description covers what the tool does, when to use it, parameter details, side effects (step reset), and unsupported fields. It even warns against speculative calls. This is highly complete.

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?

Despite 0% schema coverage in the description, it adds significant meaning: explains the id comes from tm.get_testCaseInstancesByTestRunId's 'Instance ID' field, status values are enums, assignee is a user ID from tm.get_organizationUsers, and each instance needs at least one of status or assignee. This goes well beyond the 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 the tool updates multiple test case instances in a single call, setting status and/or assignee per instance. It distinguishes from sibling tools like tm.update_testCaseInstance by noting that environment_id and remarks are not supported here.

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 explicitly recommends using this tool over calling tm.update_testCaseInstance repeatedly for batch updates. It also tells when not to use it (for environment_id/remarks) and directs to tm.update_testCaseInstance instead.

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