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

No annotations exist, so the description must carry the safety profile — and it does, stating 'Read-only' explicitly and adding the valuable disclosure that 'Tokens are never returned', which prevents agents from expecting secrets. It stops short of saying whether the list is workspace-scoped to the caller's permissions or what happens when no integrations exist.

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 dense sentence plus two short clauses; the resource and returned fields are front-loaded and nothing is redundant. Every phrase (including the token exclusion) contributes information.

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?

With no output schema, the description usefully sketches the return shape (status, account, sync settings, counters), which is what an agent needs to decide to call it. Minor gap: no mention of provider coverage limits beyond the two named examples, so it's unclear whether other CRMs could appear.

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 and the schema is an empty object, so there is nothing for the description to disambiguate. Baseline 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?

Names the resource precisely ('External CRM connections of the workspace') and enumerates the returned fields (status, account, sync settings, counters). It distinguishes itself implicitly from connect/disconnect/get_crm_integration by being the plural enumerator, though it never names those siblings explicitly.

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?

Usage is implied by the plural listing framing, and 'Read-only' signals this is a safe inspection call. But with a sibling get_crm_integration in the toolset, the description gives no guidance on when to list all vs. fetch a single integration.

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