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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds a behavioral trait annotations cannot express: that this tool is the ordering prerequisite ('Call this first'), which materially affects how an agent sequences its calls. It stops short of saying what 'learn' actually yields, but the output schema exists to cover that.

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 sentences, no filler, with the imperative 'Call this first' placed at the end as the actionable takeaway. The nine-verb enumeration is somewhat list-heavy, but it efficiently communicates the breadth of the lifecycle the tool introduces.

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 an output schema present, the description need not explain return values, and with full annotations the safety profile is covered. What remains is scope and ordering, both supplied. It is slightly thin on what the returned content actually looks like, but nothing required to invoke a zero-arg bootstrap tool is missing.

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 (additionalProperties: false), so there is no parameter semantics burden to carry; baseline 4 applies. The description's verb list describes capability scope rather than arguments, which is appropriate here.

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 frames a specific role: a bootstrap/discovery tool that teaches an agent the StewAI recipe lifecycle, and the enumerated verbs (authenticate, preview, run, commit, etc.) map onto the sibling tools, implicitly positioning this as the meta-entry-point. 'Learn how any MCP agent can...' is slightly soft as a verb, but the scope is unambiguous enough to distinguish it from the operational 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?

'Call this first' is an explicit, actionable sequencing directive that tells the agent exactly when to reach for this tool relative to the run/build/recipe siblings. It does not spell out exclusions or name a specific alternative, but for a zero-arg entry point the guidance is clear.

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