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

With no annotations, the description itself discloses the mixed read/write behavior, authorization requirements, refusal of group-level widening, and `clear`'s inheritance behavior. It also explains that uncovered tools and operations become hidden and refused with `access_level_denied`, consent requests only the level's scopes, and widening requires new consent.

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 purpose is front-loaded, followed efficiently by operation semantics, scope rules, and enforcement consequences. The dense slash-and-parenthesis notation packs in substantial useful detail but is harder to scan than a short structured list.

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 seven-parameter mixed read/write tool with no annotations or output schema, the description covers most essentials: applicability, operations, returned information, permissions, inheritance, enforcement, and consent effects. The unexplained `_org` parameter and absence of explicit sibling differentiation keep it from being fully 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?

Despite 0% schema description coverage, the text supplies meanings for all `op` values, `name` and `level` for `set`, both `scope` choices, and the scope-specific `org_id` and `group_id` parameters. The `_org` parameter is never explained, while `name`'s role as the connector identifier and the exact parameters expected by `get` and `clear` remain implicit.

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 identifies the resource as access levels for OAuth connectors that declare them, gives zoho/zohodesk and `read`/`full` examples, and enumerates the `get`, `set`, and `clear` operations. It does not explicitly distinguish this tool from related siblings such as `oto_connector` or `oto_connector_activation`.

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?

Operation-specific guidance explains what `get` reports, that `set` uses `name` and `level`, and that `clear` restores the level above. Scope guidance distinguishes org admin from team lead usage and states that groups are restrict-only, although there is no explicit routing to alternative tools for other connector-management tasks.

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