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

With no annotations, the description carries the full behavioral burden. It helpfully discloses that the call is free, requires no key, and is idempotent, and it lists returned content, but it does not clarify side effects, whether any state is created or modified, or what happens when agent_id is supplied.

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?

The description is front-loaded with 'START HERE' and packs the key facts into a compact paragraph. Some terminology ('Atomadic control surface', 'proves the superpowers') is promotional and could be tighter, but overall it is appropriately sized and structured.

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?

There is no output schema or annotations, so the description does most of the explanatory work. It lists the main return items and notes that the call is free, keyless, and idempotent, which is enough for an agent to invoke it correctly, though it leaves the exact 'control surface' concept and state effects vague.

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%, and the single optional agent_id parameter is fully documented in the schema. The description adds no additional meaning about how agent_id affects onboarding tracking, so the baseline of 3 is appropriate.

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 states a specific action ('Initialize your Atomadic control surface') and enumerates what the call returns (setup steps, runnable demo, recon links, bootstrap). It is clearly an onboarding entry point, though the term 'Atomadic control surface' is opaque and it does not explicitly name or contrast with any sibling tool.

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 opening 'START HERE' gives strong contextual guidance for when to use the tool, and 'Idempotent — re-call anytime to re-check' clarifies repeat usage. It does not provide when-not-to-use conditions or name alternatives, but the usage context is clear.

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