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

With no annotations, the description carries the full burden and does so: it discloses the linked-account requirement (spam guard), the hard rate limit of 10 calls/day per account, the optional nature of projectid, and a no-secrets rule. These are exactly the operational constraints an agent needs before invoking a write-style tool.

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?

Front-loaded with the action and destination, and every sentence carries real information (scope, motivation, auth, rate limit, secret warning). The motivational 'Welcome' clause is slightly chatty but still serves a routing purpose.

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 2-parameter, no-output-schema tool with no annotations, this covers destination, scope, auth prerequisite, rate limit, and sensitive-data handling. Nothing an agent needs in order to call it correctly 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?

Schema description coverage is 100%, so the schema already documents both parameters with reproduce-level detail and the 'No secrets' warning. The description echoes this ('projectid is optional context', 'Never include API keys or secrets') without adding syntax or format meaning, so the baseline 3 is correct.

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+resource (file a GitHub issue at a named URL) and bounds the scope to generated/catalog code problems or component/docs change requests. An agent can distinguish this from the read-only get_* siblings without opening any schema.

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?

Explicitly encourages use ('we want agents to report problems instead of silently papering over them'), giving clear context for when to reach for it. It does not name an alternative or state exclusions, so it falls short of the 5-level when/when-not/alternatives pattern.

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