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

Adds real context beyond the readOnly/idempotent annotations: the call requires no credentials, and credential configuration happens through a separate secure settings screen rather than this tool. The note about MCP approval requirements and business workflow approvals is somewhat tangential but does disclose governance behavior.

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 short sentences, front-loaded with the core action. The final sentence on approval requirements is only loosely connected to getting integration status but is not long enough to be wasteful.

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 values need not be explained. The description covers the key ambiguity for this tool—that no credentials are needed to read status—leaving only minor gaps such as error behavior when the integration is not configured.

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?

The tool takes zero parameters, so there is nothing for the description to disambiguate; the baseline of 4 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?

States a specific verb and resource: read the Smartshifts integration status. The vendor name in the tool name and the parallel sibling tools (get_credentialcamp_integration_status, get_incidentvault_integration_status, etc.) make the target obvious, though the description itself does not explicitly contrast with those siblings.

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?

The description implies usage by noting the status can be read without credentials and that credentials are configured elsewhere, which tells the agent this is a safe pre-setup check. However, it never states when to prefer this over another tool or what to do if the status comes back unconfigured.

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