BlockVectra: multi-chain RPC & Data API

OverviewDiscussionsAdmin

Search Documentation

search_docs
Read-only

Find documentation by topic or task keywords when the page path is unknown. Searches page titles, navigation titles, relative paths, and page summaries, returning titles, relative paths, and summaries. Read a result with read_doc using its path and the same lang; use read_doc directly for a known path or list_docs to browse the documentation catalog. Omit lang for English; limit is 1-20 (default 5). If no results match, try broader keywords or browse list_docs. Available without an API key.

Input Schema

NameRequiredDescriptionDefault
langNoPublished documentation language (case-insensitive, e.g. zh-hant or zh-Hant). Omit for English; unavailable languages return an error.
limitNoMaximum number of search results to return (1-20, default 5).
queryYesKeywords to search for in documentation titles, navigation titles, paths, and summaries.

  13. First observed

TDQS

A4.4/5.0
Behavior4/5

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

Annotations already declare readOnlyHint and openWorldHint=false, but the description adds real value beyond them: it states the tool works without an API key, lists what it returns (titles, relative paths, summaries), and prescribes recovery when nothing matches. It doesn't discuss pagination or ranking, which keeps it from a 5.

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 purpose and routing before operational details, and every sentence carries information (search scope, handoff, defaults, fallback, auth). It is dense and slightly run-on across topics but wastes little.

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

Completeness5/5

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

For a three-parameter search tool with an output schema, the description covers everything an agent needs: purpose, search fields, routing to siblings, language/limit handling, failure recovery, and API-key requirement. Nothing material is left ambiguous.

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 coverage is 100% and the schema already documents lang's default (omit for English), the enum, and the limit range (1-20, default 5). The description largely restates these, adding no syntax or semantic detail 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.

Purpose5/5

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

States a specific verb (Find/Searches) and resource (documentation), and explicitly scopes it to the case where the page path is unknown. It names which fields are searched and clearly differentiates itself from read_doc and list_docs.

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?

Gives explicit routing: use read_doc for a known path, list_docs to browse, and this tool when the path is unknown. It even covers the no-results fallback (broaden keywords or use list_docs), so an agent never has to infer the alternative.

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