appwrite_create_subscriber

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

No annotations provided, so description carries full burden of behavioral disclosure. Fails to specify if this is idempotent, what happens if the subscriber already exists, or the relationship between subscriber_id and target_id parameters. No mention of auth requirements or rate limits.

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?

Brief single sentence, but the '[UNIFIED]' prefix appears to be metadata noise rather than descriptive content. While not verbose, the extreme brevity is inappropriate given zero schema documentation and lack of annotations.

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?

Insufficient for a creation tool with 4 undocumented parameters and no output schema. Lacks explanation of return values, error conditions, or the entity relationships (particularly the distinction between subscriber_id and target_id which is critical for correct invocation).

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 has 0% description coverage with 4 required parameters. Description only implicitly maps 'topic' and 'subscriber' to topic_id and subscriber_id, leaving 'site' and 'target_id' completely unexplained. Doesn't clarify parameter formats or constraints.

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 the basic action clearly with 'Add a subscriber to a topic' - specific verb and resource. However, lacks differentiation from sibling `appwrite_create_topic` (which creates the topic itself) and doesn't clarify what constitutes a 'subscriber' in the Appwrite context (user, endpoint, device?).

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 on when to use this tool versus alternatives, prerequisites (e.g., does the topic need to exist first?), or failure modes. The '[UNIFIED]' prefix suggests a specific architectural pattern but provides no actionable context for the agent.

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