CoinRithm Agent Trading

Resolve symbol -> coinId

resolve_symbol

Read-only

Resolve a human symbol / slug / name (e.g. 'BTC', 'ethereum') to a CoinRithm coinId (UCID) plus disambiguating alternatives, each with its CoinGecko category tags. Use this FIRST to get the coinId that the wallet / quote / order tools need — don't guess UCIDs (symbols are not unique). Paper trading only (virtual mUSD). Fills follow paper_execution_v1 with a disclosed execution cost; see executionModel in quote/trade results.

TDQS

A4.3/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, openWorldHint, and destructiveHint=false, so the safety profile is covered. The description adds genuine context beyond that: paper trading only (virtual mUSD), fills follow paper_execution_v1 with a disclosed execution cost, and executionModel appears in quote/trade results. Some of that execution detail belongs more to the trade tools than to a resolver, but the environment constraint is useful.

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, followed by usage routing, then environment notes — a sensible order with minimal waste. The trailing sentence about paper_execution_v1 and execution cost is slightly tangential for a pure resolution tool, trimming it to a 4.

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?

An output schema exists, so return values needn't be re-explained, and the description covers purpose, usage ordering, and environment. The only soft spot is that the execution-cost sentence is more relevant to downstream quote/trade calls, but it does no harm.

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 both `q` and `agentTrace` (with its nested fields) are already documented in the schema. The description's format examples ('BTC', 'ethereum') restate what the schema provides, adding little beyond the baseline.

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?

Specific verb+resource: 'Resolve a human symbol / slug / name ... to a CoinRithm coinId (UCID) plus disambiguating alternatives, each with its CoinGecko category tags.' It clearly names its output and its role relative to the wallet/quote/order tools, so an agent can distinguish it from siblings without opening the schema.

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

Usage Guidelines5/5

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

'Use this FIRST to get the coinId that the wallet / quote / order tools need — don't guess UCIDs (symbols are not unique)' gives explicit ordering, names the dependent tools, and states an exclusion (don't guess). Nothing about when to invoke is left to inference.

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