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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and a closed-world scope, so safety needs no restating. The description still adds real, non-annotation context: tokens are never returned (only the last 4 characters), which ones are server_provided, and whether the server can persist tokens. That is a meaningful security disclosure, though it says nothing about empty-state behavior or when providers appear.

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?

One dense but purposeful sentence covering providers, redacted token, server_provided, storage capability, and the out-of-scope dashboard actions. There is no filler, though the nested parentheses and multiple clauses make it heavier to scan than an ideal front-loaded opening would be.

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?

An output schema exists, so return-shape detail is optional yet the description still characterizes the key fields, and the annotations carry the safety profile. The only remaining gap is that workspace scoping is delegated entirely to the schema, which is adequate for a read-only single-parameter lister.

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?

With a single parameter and 100% schema description coverage, the schema fully explains workspace_id, including defaults for API-key and single-workspace callers. The description never mentions workspace scoping, so it adds nothing beyond the schema; the baseline 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 names the concrete resource (providers such as HubSpot and Calendly connected to this workspace) and enumerates exactly what the listing conveys: label, last four token characters, server_provided flag, and token-storage capability. It is a noun phrase rather than an explicit verb, so the action 'list' is inferred from the name and title, but the content is unmistakable and no sibling in the catalog covers integrations.

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 gives a clear use context and an explicit exclusion: 'Connecting or disconnecting a provider happens in the dForms dashboard; no tool here does it,' which stops an agent from hunting for a connect/disconnect tool. It stops short of stating when to call this versus inspecting providers through other means (e.g., list_hubspot_properties), so it is not a full 5.

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