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

Annotations provide only destructiveHint=true, so the description carries the remaining burden and adds almost nothing: it does not say that creating a conversation may email the customer/recipients, whether it is idempotent, what happens on duplicate subject, or what auth scope is required. For a write tool with side effects (outbound notification), that is a real gap.

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?

Two short, front-loaded sentences with no filler; the core action leads and the REST endpoint trails. The 'POST /conversations' fragment is mildly redundant for an agent but harmless and occasionally useful.

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 9 parameters, 100% schema coverage and no output schema, the schema side is covered, but the description omits the return value (presumably the created conversation/id) that an agent needs to chain a follow-up call. Nothing on side effects or failure modes either.

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 description coverage is 100%, including the status enum mapping and which fields are required, so the baseline of 3 applies. The description adds no parameter-level detail beyond noting the message is the 'first message', which the schema already implies.

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+resource ('Create a new conversation') and disambiguates the domain term by equating it with 'support ticket'. It also notes the tool creates the first message in the same call, which cleanly separates it from reamaze_reply_conversation and reamaze_create_contact.

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?

No when-to-use guidance is given: nothing tells the agent to prefer this over reamaze_reply_conversation when a conversation already exists, nor any prerequisite (e.g. the channel slug must already exist, customer may need to exist). Usage is only inferable from the name.

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