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

With no annotations, the description carries the full burden and does disclose the read-only scope, the URL-approval flow, and the drop behavior of disconnect. It could add consequences of disconnect or whether reconnection requires a fresh URL, but the core behavioral traits are present.

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 main behavior is front-loaded, but the purchase_scaffold sentence is grammatically confusing and the overall structure mixes tool behavior, user instructions, and workflow context without clear separation. It is not bloated enough for a 2, but not crisp enough for a 4.

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?

For a single-optional-param tool with no annotations and no output schema, the description covers the connect flow, disconnect behavior, and a follow-up scaffold step. It could mention verifying via get_github or the exact return shape, but an agent has enough context to invoke it correctly.

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 coverage is 100%, so the baseline is 3. The description repeats 'disconnect: true drops the connection' but adds no meaning beyond what the schema already states; the schema already documents the omit-to-mint-URL behavior.

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 concrete behavior: it returns a GitHub App install URL to grant read access to one repo, and 'disconnect: true drops the connection.' This maps clearly to the title. It does not explicitly differentiate itself from get_github, and the purchase_scaffold sentence adds noise, so it is not a full 5.

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 description gives usable context: prefer signing in on botkelp.com first, and after approval use purchase_scaffold with the provided template_files. It does not enumerate exclusions or explicitly compare with get_github, but the workflow is clear enough for selecting this tool.

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