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

Annotations already declare readOnlyHint=true, so the safety profile is covered; the description still adds real behavioral context that executions are organisation objects, that no cluster is needed to read one, and that organisation-scoped executions (registry syncs, chart reads) have none. It omits pagination, result size, and error-excerpt truncation behavior. Note a tension with the schema, which marks cluster_id required while the description says some executions need no cluster.

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 sentences, front-loaded with what is returned, then when to use it, then the scoping nuance. No filler and each sentence carries distinct 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?

No output schema exists, so the description correctly enumerates the return payload (steps, statuses, error excerpts) itself, and it covers the org-vs-cluster scoping the caller needs. For a two-param read tool this is 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?

Schema coverage is 100%, so the baseline is 3; however the description adds meaning about cluster_id's relevance by explaining that organisation-scoped executions have no cluster at all, which is not stated in the schema. It leaves the conflict with the required cluster_id unresolved, which caps this below 5.

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?

Specific verb ('Get') plus resource ('full details for a specific execution') and an explicit content inventory (all steps, statuses, error excerpts). This clearly separates it from list_recent_executions, get_execution_trends, and wait_for_execution.

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?

States a concrete trigger: 'when you have an execution_id from list_recent_executions and need to drill into the failing step.' It names the upstream tool that supplies the required id, which is strong routing context, though it gives no explicit when-not-to-use or mention of sibling detail tools.

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