ingest_realtime_webhook

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

It discloses a key behavioral trait: it verifies webhook authenticity via HMAC-SHA256. However, it does not explain what happens on invalid signatures, retries, idempotency, or other operational behaviors, which is a gap given there are no annotations to cover the safety profile.

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 concise: two sentences, front-loaded with purpose and key detail. It wastes no words and is easy to scan.

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?

The output schema exists to describe returns, and the description covers core purpose, destination, and authentication. It lacks details like failure handling or parameter specifics, but it provides enough for an agent to locate and invoke the tool correctly. It is more complete than typical descriptions in this set.

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?

The description indirectly clarifies parameters: event_type is the kind of event, source_platform might be CMS/email/social, payload_json is the event data, and hmac_signature is the auth key mentioned in HMAC-SHA256. Yet it does not explicitly map these, leaving room for misinterpretation, especially with 0% schema coverage.

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 clearly identifies the tool's function: it ingests high-velocity real-time events (CMS, email opens, social mentions) into the Hot Tier. This specific verb-resource pair and the real-time vs batch distinction differentiate it from sibling tools like ingest_batch_api_poll.

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 implies the tool is for real-time webhook ingestion ('high-velocity, real-time events') and verifies authenticity, which gives context for when to use it. However, it does not explicitly mention alternatives, exclusions, or when not to use it, leaving some ambiguity.

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