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

Annotations already declare readOnlyHint, destructiveHint=false and openWorldHint=false, so 'Free, read-only' is largely redundant. The description does add useful content-scope context (which topics the snippet covers, that it flags paid tools), but nothing about format, length, or return shape.

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 key deliverable is front-loaded in the first clause, followed by scope and usage guidance. The second sentence is dense with enumerations but each item earns its place; slightly long, though not wasteful.

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?

No output schema exists, so the description must convey what comes back — and it does, describing the snippet's purpose and coverage. It stops short of describing format or how to detect success, which would fully close the gap for a no-arg retrieval tool.

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?

Zero parameters, so per the rubric the baseline is 4. There is no parameter semantics to add meaning to.

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 resource — the paste-able 'Growth (AfterLaunch)' section for CLAUDE.md/AGENTS.md — and enumerates the subject matter it covers. No sibling tool overlaps with this output, so the agent can identify it immediately.

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?

Gives clear usage direction ('Show it to the founder and add it with their say-so') and the context in which it applies (agent setup). It does not name alternatives, but none exist among the siblings for this specific artifact, so the lack of exclusions is minor.

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