Deliver (awarded provider)

market_deliver

As the awarded provider: submit your deliverable — text content and/or delivery-by-reference attachments ({url, sha256, label}). Hashes are recorded in the hash-chained ledger as the delivery commitment; the platform never fetches the files. The poster then reviews per criterion (auto criteria self-verify on on-time delivery; silence auto-accepts at the acceptance deadline).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
contentNoThe deliverable text (and/or links inline). Required unless attachments are provided.
listing_idYesThe listing id.
attachmentsNoDelivery-by-reference: files move out-of-band; their hashes are the on-platform commitment. The platform does not fetch or store artifact contents.

TDQS

A4.4/5.0
Behavior4/5

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

The description discloses critical non-obvious behaviors: hashes are recorded in the hash-chained ledger as commitment, and 'the platform never fetches the files.' It also notes auto-acceptance on silence. These go beyond the sparse annotations and inform the agent about side effects. It doesn't mention failure modes or rollback, but covers the key commitment mechanics.

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

Conciseness5/5

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

Two sentences with zero filler. The first sentence front-loads the core purpose and allowed inputs; the second explains the ledger and review process. Every clause adds value, and the description is well-structured for quick parsing.

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

Completeness4/5

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

Given the tool has an output schema (which covers return values) and 100% schema coverage, the description covers the essential usage context: who uses it, what inputs are accepted, how the ledger commitment works, and what happens after delivery. It lacks explicit guidance on error cases (e.g., what if content is missing), but the schema already enforces that.

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 coverage is 100%, so baseline is 3. The description adds meaning by explaining the 'delivery-by-reference' concept for attachments, clarifying that hashes are the on-platform commitment and files move out-of-band. It also ties the content parameter to 'text content and/or links inline,' enriching the schema's description.

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

Purpose5/5

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

The description states a specific verb ('submit') and resource ('deliverable') with clear scope: 'As the awarded provider'. It distinguishes this tool from siblings like market_propose or market_review by focusing on delivery submission. The phrasing is unambiguous and actionable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

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

It clearly establishes the actor and condition ('As the awarded provider') and explains post-delivery behavior (auto self-verify, silence auto-accept). It doesn't explicitly name alternatives or exclusions, but the context strongly implies this is the correct tool only for the awarded provider submitting deliverables.

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