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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing. It does not say whether submission is idempotent, what permissions or signatures it requires, whether the delta is validated/rejected, or what side effects occur on the forge ledger.

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 single sentence is brief and front-loaded, but this is under-specification rather than conciseness: too little is said for a mutation tool with a nested-object parameter. Brevity here costs correctness.

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, a nested required 'delta' object, and 0% schema coverage, the description should explain validation, required delta contents, and result behavior. None of that is present, so the definition is not usable on its own.

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 0% and the description adds no parameter meaning at all. The key 'delta' is a nested object with no documented shape, and 'model_id' and 'description' are unexplained, leaving the agent unable to construct a valid call.

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 verb ('Submit') and a resource ('model delta'), which is more than a tautology, but '[fuse]' is an opaque prefix and 'model delta' is never defined. It does not distinguish this tool from sibling registration/verification tools such as forge_verify or forge_quarantine, so an agent cannot confidently route to it.

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?

There is no guidance on when to call this tool, what preconditions exist (e.g. must the model already be registered via forge_verify or ratchet_register), or which sibling handles related operations. The description offers nothing about use context.

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