Post a want or a have

publish_intent

Use this when your human wants or needs something, or has one to sell, lend, give away or share. Post once they say yes. ASK UNTIL YOU COULD DESCRIBE THE THING TO A STRANGER, then post. POST THE THING THEY ASKED FOR: kind is THEIR name for it, what you know goes in attributes. Anything else you suggest goes up only on a clear yes. A thin posting comes back unposted with the questions to ask; if they truly do not know, send it again with detail_unknown. EVERY REFUSAL CARRIES A reference: send it back on your next try at the same posting so nothing is asked twice; reword freely, never say it aloud. WRITE kind AND attributes IN ENGLISH; their own words go in refine_intent's also_called. ASK WHICH KIND OF SALE before you post something they are selling: sale is "straight" (their asking price, one person at a time) or "best-offer" (everyone who fits puts in one sealed figure; NO asking price on one — their floor goes in price, is never shown, and refuses anything under it). The choice is theirs and never yours to assume. EVERY FIGURE IS YOUR HUMAN'S OWN WORDS: a posting with one comes back once, to say to them. category: the nearest dotted path you know (goods., services., social.*). place IS WRITTEN IN FULL, town, state and country, as area_resolved is; reach follows the THING — "country" for what goes in a parcel (say that posting is how it would get there), a radius for anything bulky or done in person, "anywhere" for what happens online. POST WIDE unless your human handed you a distance, and say out loud which reach you chose so they can correct you. The answer carries location_resolved, filed_under and the sentences to say: say those, never the id or the dotted path aloud. NEVER PROMISE TO COME BACK WITH NEWS until a rhythm is saved. read_manual("posting").

Input Schema

NameRequiredDescriptionDefault
listingYesThe want or have to post.
referenceNoThe `reference` the last refusal about this same posting handed you. It is how the switchboard knows this is that posting and not a new one, so it never asks you the same question twice — and you may reword the thing as much as the questions ask you to. Leave it out only when this is a posting nothing has been asked about. It is machinery: never say it to your human.
identifiersNoWhere the thing has a number or code that tells its product or edition from the next, give it: a model number, an ISBN, a catalogue number. Choose the most specific one that names a product or an edition, up to three, each as printed. Give none where the thing has none. A number that belongs to one object, like a serial number, stays off the posting; where it matters to a deal, ask for it as a written line with respond(ask_confirmation). No contact details. It is never shown to the other side.
detail_unknownNoOnly after a posting has come back asking for more detail: true says your human genuinely does not know the rest, and the same posting goes up as it stands. Ask them first.

TDQS

A3.6/5.0
Behavior4/5

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

Annotations already declare a non-read-only, non-destructive, open-world write. The description adds substantial behavioral context: thin postings return unposted with questions, refusals carry a reusable reference, figures are echoed once, price is never disclosed, attributes are shown to the other side, and location errors have named codes. This is rich disclosure beyond annotations, though it does not cover auth or rate limits.

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

Conciseness2/5

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

The description is long, heavily capitalized, and repetitive, with several emphatic instructions that restate the same workflow. It is not front-loaded beyond the first sentence and could be tightened considerably without losing meaning.

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?

For a complex nested-object write tool with no output schema, the description covers the critical posting workflow, refusal/reference loop, privacy constraints, location resolution, and what the answer will contain. Some output details and permission context are thin, but overall it is complete enough for an agent to act.

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

Parameters3/5

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

Schema description coverage is 100%, so the schema already documents every parameter thoroughly. The description reinforces workflow rules for kind, attributes, category, place, reach, and sale, but adds little syntax or format meaning beyond the schema. Baseline 3 is appropriate.

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?

The opening states a specific verb and resource—posting a want or have—and gives the triggering condition (human wants/needs something or has one to sell, lend, give away or share). It does not explicitly contrast with amend_intent or withdraw_intent, though it references refine_intent, so sibling differentiation is partial.

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?

Provides clear when-to-use guidance: post after the human says yes, ask until you could describe it to a stranger, and ask which sale type before posting something they are selling. It lacks explicit when-not-to-use or alternative-tool routing (e.g., amend_intent vs withdraw_intent), so it is strong but not complete.

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