search_tickersFuzzy lookup: returns free-subset rows whose ticker symbol or company name contains the query (case-insensitive). For structured filter/rank, use get_screen_data instead.
| Name | Required | Description | Default |
|---|---|---|---|
| query | Yes | Substring to match against ticker symbol or company name. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint and openWorldHint, and the description adds behavioral details beyond those: case-insensitive substring matching and returning rows that contain the query. The phrase 'free-subset rows' is somewhat vague but does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two concise sentences, front-loaded with the primary action and followed by a useful alternative reference. No wasted words.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a single-parameter search tool with read-only annotations and no output schema, the description covers the core behavior and provides an alternative. The 'free-subset' phrase introduces minor ambiguity but does not undermine overall completeness.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%; the only parameter 'query' is fully described in the schema. The description does not add meaning beyond the schema, so the baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('lookup') and resource ('tickers'), clearly stating it matches by symbol or company name via fuzzy substring. It also explicitly distinguishes itself from get_screen_data, making its purpose unambiguous.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description clearly indicates a use case (fuzzy lookup) and explicitly recommends an alternative (get_screen_data) for structured filter/rank. However, it does not contrast with list_tickers, leaving a slight ambiguity for when to use each sibling.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Each tool has a clearly distinct purpose: get_rr_score provides detailed analysis for a specific ticker, get_screen_data offers filterable/rankable cross-sectional data, list_tickers simply enumerates all symbols, and search_tickers performs fuzzy lookup. There is no functional overlap between these operations.
All four tools follow a consistent verb_noun snake_case pattern: get_, get_, list_, search_. The naming is uniform and predictable, making it easy for an agent to infer the action and resource for each tool.
Four tools is well-scoped for a specialized analytics server. The set covers the essential operations—single-asset deep dive, screening, directory listing, and search—without unnecessary bloat or missing core functionality.
The tool surface is complete for the stated domain of free-subset precious-metals analytics. Users can discover the universe (list_tickers), locate specific companies (search_tickers), get detailed 9-factor scores (get_rr_score), and perform structured screening (get_screen_data). No obvious gaps or dead ends are apparent.
