deploy_release_active

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

No annotations provided, so description must carry behavioral burden. It mentions the null return case and that canonical SDK errors are preserved. However, it does not disclose required permissions, data freshness, or any potential side effects. Adequate but not exhaustive.

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?

Three concise sentences covering action, edge case, usage, and error behavior. Front-loaded with the core purpose. No redundant information.

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 simple read tool with 2 parameters and no output schema, the description covers the core function, null case, and usage context. It lacks details on response structure beyond release_id, but given the low complexity, it is reasonably 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?

Input schema has 100% description coverage for both parameters. The description adds no additional meaning beyond what the schema provides (e.g., 'project_id' and 'site_limit' are already documented). Baseline score of 3 applies.

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 'Fetch the current-live release inventory for a project' with a specific verb and resource. It also explains the null case when no release is active and provides workflow context ('Use this before deploy diffs'), distinguishing it from sibling tools like deploy_release_diff.

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 says 'Use this before deploy diffs to understand what is currently serving', giving clear context for when to invoke. Lacks explicit when-not-to-use or alternative tool references, but the guidance is actionable.

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