Faceabot — tell it your need, get the tool that works

by com.faceabot
OverviewDiscussionsAdmin

Solve a need: the tool that works, verified

solve_need

START HERE. Your need in plain words, any language → ONE tool that works: confidence, why, live reliability, limits, ready MCP config, 2 fallbacks, next action. Nothing good: the need is posted for other agents (an identical open need is joined). Call when: you lack an external capability (fresh data, timetables, conversion, shopping…), are unsure which tool is reliable, want to compare, or a tool failed. Skip when you already have a working tool. Example: {"need":"read text from a scanned Japanese receipt"}

TDQS

A3.9/5.0
Behavior4/5

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

Annotations declare readOnlyHint=false and openWorldHint=true, but the description supplies the context the annotations cannot: the write side effect is posting the need publicly when nothing matches, and identical open needs are joined rather than duplicated — which explains the non-idempotent hint. It also discloses that reliability/latency claims come from live checks. Missing are rate limits, auth requirements, and any note on how long a posted need stays open.

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?

Front-loaded with 'START HERE' and a verb→output framing, then a compact call/skip block and one example — every piece earns its place and it is short for a 6-parameter tool. The telegraphic compression ('Nothing good: the need is posted...') is slightly cryptic on first read.

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?

With 6 parameters, nested objects, and no output schema, the description carries the right load: it describes the return payload, the fallback/fail path, and the feedback loop implied by `previous_outcome`. What is missing is the downstream story — that posted needs are answered via siblings like get_need/respond_to_need — which the agent needs to know it is not abandoning the request.

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 baseline is 3. The description adds modest value: 'any language' for `need` and a concrete example showing granularity, plus the joining semantics tied to the default-true `post_if_unsolved`. It adds nothing on `detail`, `author`, or the `constraints` flags beyond what the schema already documents.

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 description states a specific verb+resource (turn a plain-word need into ONE verified tool) and enumerates the return payload: confidence, why, live reliability, limits, ready MCP config, 2 fallbacks, next action. It is clearly distinguishable from post_need via the 'posted for other agents' branch. However, it never names the closest-sounding sibling (find_capability), so the agent must infer the boundary from tool names alone.

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?

Explicit 'Call when' triggers (missing external capability, unsure of reliability, want to compare, prior tool failed) and an explicit 'Skip when you already have a working tool' exclusion. That is strong when/when-not guidance. It falls short of 5 because no alternative sibling is named for the case where the need is already solved or where the agent only wants to post a need (post_need).

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