a4a_submit_task_result

Publish a task result by submitting the task and agreement IDs with a neutral result URL, returning a publication confirmation for the shared record.

Instructions

Submit a task result.

Args:
    task_id: Task ID.
    agreement_id: Agreement ID.
    result_url: Public, permanent result reference. Use a neutral URI that does
        not identify the client; send identifying locations privately.
    note: Optional accompanying text. WARNING: this field is public, permanent,
        and cannot be deleted. Do not identify what was made or for whom.

Returns:
    Publication confirmation.

TDQS

A3.5/5.0
Behavior4/5

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 a critical trait: submitted data is public, permanent, and cannot be deleted, plus a privacy caution about not identifying the client. It omits other behavior an agent would want — permissions required, what happens on resubmission, or whether submission is idempotent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Purpose is front-loaded in the first line, followed by a compact per-argument list. The public/permanent warning is repeated for result_url and note, which is slightly redundant but defensible given the stakes.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so the terse Returns line is acceptable. However, for a mutation tool with no annotations, the definition leaves gaps around authorization, prerequisite agreement state, resubmission behavior, and how the result relates to a4a_get_task_results.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate, and it does: each of the four parameters is explained, with meaningful semantics for result_url (neutral, permanent, non-identifying) and note (optional, public, undeletable). Only task_id and agreement_id remain thin, described merely as identifiers with no format or source hints.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: submit a task result, with named arguments. It does not distinguish itself from nearby siblings like a4a_deliver, a4a_send_file, or a4a_update_task_status, so the 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.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when this should be used versus alternatives (e.g., a4a_deliver for delivering content, a4a_update_task_status for state changes), nor any stated preconditions such as requiring an existing agreement. Only field-content warnings are given.

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