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 real behavior: retry-until-max_attempts then permanent dead state, the required X-Queue-Key header, plus cost ($0.001 via x402) and production endpoint. It omits idempotency, permission requirements, and what happens to job state afterward, but the retry/dead-letter semantics are the key trait an agent needs.

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 core sentence is front-loaded and efficient, but the parenthetical about AYNE playzone, production URL, and price plus the 'By OMENZ' attribution consume roughly half the text. Cost and endpoint have some operational value; the branding does not earn its place.

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 6-parameter mutation tool with no annotations and no output schema, the description covers the behavioral outcome and endpoint/cost but leaves parameter semantics and return behavior largely undefined. It is adequate to recognize the tool's role but not to invoke it confidently without reading the schema.

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 only 17% — only x_queue_key is documented — and the description merely repeats that same header, adding nothing. The other five parameters (retry, reason, item_id, queue_id, worker_id) are unexplained in both places, and with zero required parameters nothing tells the agent which are mandatory to report a failure.

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 names a specific actor and action ('worker reports failure') and states the outcome chain ('job retries until max_attempts, then goes dead'). This distinguishes it in spirit from queue_complete or queue_resolve, but it never names a sibling explicitly, so an agent must infer the boundary.

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?

Usage is implied by the retry/dead-letter outcome, which tells an agent this is the terminal-failure path. However there is no explicit when-to-use versus when-not guidance, and no routing to alternatives such as queue_escalate or queue_complete for non-failure terminations.

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