push_setup_fcm

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

No annotations are provided, so the description must carry the behavioral burden. It only says 'Generate... integration' and does not disclose side effects, file modifications in the project directory, required credentials, prerequisites, or whether this is a read-only scaffold or a mutating setup operation.

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 a single short sentence with no wasted words and is easy to scan. It is concise, but it is also quite sparse and relies heavily on the tool name to carry meaning.

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 no annotations, no output schema, and only this brief description, the tool is not contextualized enough for reliable use. The agent is not told what files are generated, whether the api_key is required for FCM setup itself or for an enterprise license, or what success looks like after invoking the 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?

Schema description coverage is 100%, so the schema already documents both parameters. The description itself adds no parameter-level meaning, but it does not need to compensate because the schema descriptions for 'directory' and 'api_key' are present and clear enough for the baseline.

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 uses a specific verb and resource: 'Generate Firebase Cloud Messaging integration.' This clearly identifies the tool's core function. However, it does not differentiate it from near-identical siblings like mobilepush_setup_fcm or the broader push_setup_web/push_setup_apns family.

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?

No guidance is given about when to use this tool versus alternatives. The sibling list contains several related setup tools, including mobilepush_setup_fcm, push_setup_web, and push_setup_apns, but the description provides no conditions, exclusions, or routing advice.

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