ensure_coverage_setup

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

No annotations provided. Description only says 'ensure' without disclosing side effects (e.g., installing dependencies, modifying workspace). Bar is high without annotations; this falls short.

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?

Single sentence, front-loaded with purpose. No unnecessary words, but could expand slightly without losing conciseness.

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 4 parameters, no output schema, and no annotations, the description is too brief. Does not explain what 'coverage commands' or 'dependencies' means, nor success/failure criteria. Incomplete for a setup 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?

Schema coverage is 50% with descriptions for two parameters, but the description adds no parameter-level meaning. The optional parameters preferredRunner and preferredCoverageProvider are unexplained beyond their names.

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 it ensures the target workspace has runnable coverage commands and dependencies. The verb 'ensure' plus specific resource and outcome distinguish it from sibling tools like fetch_uncovered_code (data retrieval) or improve_test_coverage_orchestrator (improvement).

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 on when to use this vs alternatives. Missing context about prerequisites, idempotency, or when setup is needed. Sibling tools exist but no differentiation.

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