Set a nested home catalog value

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

Annotations already declare readOnlyHint=false and destructiveHint=false, so no contradiction. The description adds that it supports dry_run and snapshots previous state before write, and that revert is possible. However, it doesn't mention any side effects like audit entries beyond the dry_run note in the schema, or what state changes are irreversible. With annotations covering the mutation hint, the description adds useful context but could say more about the snapshot mechanism.

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 short and front-loaded with the deprecation warning, which is good. But it packs multiple ideas (deprecation, set operation, dry_run, snapshot, revert) in two sentences, which could be more readable. Every sentence earns its place, but the length is marginal for the guidance it gives.

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 that it's a deprecated tool with a replacement, the description covers deprecation, usage, and basic behavior enough for an agent to know to prefer the alternative. However, it does not explain the exact dot-path syntax or the interaction with profile_id/platform, which are critical for a correct call if the agent does use it. It's adequate but not complete given the 5 parameters and no output schema.

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 only 20%, so the description must compensate, but it only mentions the 'path' and 'value' implicitly via 'dot path' and 'value' in the text. It does not explain the format of 'path' (e.g., dot notation) beyond that phrase, nor does it describe 'platform', 'profile_id', or 'dry_run' semantics beyond what the schema provides. Since the description is brief, it adds minimal value, and with 5 parameters it should do better.

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 sets a nested value by dot path inside the home catalog settings blob, with a deprecated status and an explicit replacement. It distinguishes from nuvio_update_home_catalog_settings by naming it as the successor, but it does not explain why this tool exists separately or what edge cases it covers, so it's clear but not fully distinct.

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?

It explicitly tells the agent to use nuvio_update_home_catalog_settings instead, and it mentions the dry_run capability and revert path via nuvio_undo. This is exceptional guidance for a deprecated tool: when to use (during migration) and when not to (prefer replacement).

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