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

With no annotations provided, the description carries the full burden of behavioral disclosure but offers minimal information. While 'submit' implies a write operation, the description does not confirm whether this creates a persistent record, what validation occurs, or whether the operation is idempotent or destructive. The notation '16w' is also unexplained (width?), creating potential confusion.

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 extremely concise with only two sentences and no filler. The core action is front-loaded in the first sentence. Minor deduction because the '16w' abbreviation in the second sentence assumes contextual knowledge without explanation, potentially requiring the agent to infer that 'w' means width and maps to the 'size' enum values.

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?

Given the 100% schema coverage and 6 parameters, the description provides adequate context for the size parameter's implications. However, for a mutation tool with no output schema and no annotations indicating destructive/write behavior, the description should explicitly confirm the creation/submission side effects rather than leaving them implied by the verb alone.

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 100%, establishing a baseline of 3. The description adds valuable semantic context beyond the schema by specifying the dimensional mapping of size tiers (16x8, 32x16, 64x32), which helps the agent understand the 'art' parameter constraints. However, it uses '16w' terminology while the schema expects '16', creating slight friction.

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 states the verb (Submit) and resource (ASCII art), making the core function unambiguous. However, it does not explicitly differentiate from siblings like 'banner' (which might generate art) or 'convert' (which might transform existing art), leaving some ambiguity about when to prefer this over creation alternatives.

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 provided on when to use this tool versus alternatives like 'convert' or 'banner', nor are prerequisites (e.g., valid ASCII characters only) or exclusion criteria mentioned. The agent must infer usage solely from the action verb.

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