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

Annotations already declare the write profile (readOnlyHint=false, destructiveHint=false, openWorldHint=true, idempotentHint=false), so the bar is lower. The description does add genuine value by disclosing the auth requirement ('Needs key or sign-in'), which annotations do not cover, but it says nothing about the existence of an `idem` dedupe key or what a created node returns.

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?

It is short and front-loads the create action, but the trailing ellipsis means a sentence was cut off rather than deliberately kept brief. Brevity here reads as under-specification rather than tight editing.

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?

This is a 7-parameter mutation tool with zero schema descriptions and no output schema, so the description is the only explanatory layer available. It provides nothing about the `idem` idempotency parameter, the `space` scoping, media attachment behavior, or expected response, leaving an agent unable to call it correctly beyond title/text.

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 0% across 7 parameters, so the description must carry the burden and it does not. Only `key` (as 'key or sign-in') is hinted at; `idem`, `tags`, `media`, `space`, `title`, and `text` receive no explanation, leaving the dedupe and space-scoping semantics entirely opaque.

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 ('Create') and resource ('a Trana node'), and enumerates the node kinds (ask, offer, result, design, problem), which tells an agent what domain object is being produced. The sentence is truncated mid-thought ('for people and agents to...'), which leaves the ultimate purpose vague and gives no explicit contrast with siblings like node_edit, node_reply, or trana_post.

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?

Beyond 'Needs key or sign-in' there is no guidance on when to create a node versus posting via trana_post, task_post, space_ask, or replying with node_reply. The enumerated kinds imply some usage but no conditions, prerequisites, or exclusions are spelled out.

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