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

The readOnlyHint annotation already establishes that this is a non-mutating read, and the description adds essentially no behavioral context beyond that: no indication of what 'status' comprises (health, version, sync state), no pagination or volume characteristics, and no noted failure modes when an addon is absent.

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?

A single front-loaded sentence with no filler or repetition. It is efficient, though the brevity comes at the cost of the sibling differentiation and usage context noted elsewhere.

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-only tool with full schema coverage and an explicit readOnlyHint, the Ankra-managed scope and cluster targeting are covered. What is missing is any clarity on what 'status' returns and how this differs from the many other addon read tools, leaving the agent to guess between near-duplicate options.

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 description coverage is 100%, and the schema already explains both cluster_id (with a pointer to list_clusters) and the optional addon_name default behavior. The description contributes nothing beyond what the schema states, so the baseline 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 gives a clear verb+resource ('Get status of installed addons/applications') scoped to a cluster, which is more specific than a tautology. However, it does not distinguish itself from close siblings such as get_addon_details, get_addon_configuration, get_addon_settings, or list_addons, so an agent cannot tell from the text which of these reports 'status'.

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?

There is no when-to-use guidance, no prerequisites, and no named alternatives despite a dense cluster of addon-related read tools. The agent must infer the use case purely from the tool name.

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