Urantia Papers

Full-Text Search

search.fulltext

Read-onlyIdempotent

Keyword search across all paragraphs of the Urantia Papers. Mode "auto" (default): a reference such as "68:6.3", "103:2", "Paper 68", or a bare number such as "68" (0 to 196) gives those paragraphs; otherwise the exact phrase first, then every word, then (when few) typo fixes and most of the words. Each result has match (reference, exact, all, near, most); meta.didYouMean gives the fixed query and meta.see names another work the query names. Other modes: "and" (all words), "or" (any word), "phrase" (exact phrase).

Input Schema

Name	Required	Description	Default
`q`	No	Alias for `query` (REST compatibility).
`lang`	No	Language to search. "es" searches the Spanish text (words match with or without accents; "documento 1" is a reference) and gives Spanish rows. Default "eng".	eng
`page`	No	Page number (0-indexed)
`type`	No	Search mode: auto, phrase, and, or	auto
`limit`	No	Results per page (1-100)
`query`	No	Search query. Example: "nature of God"
`part_id`	No	Filter to a specific part ID (1-4)
`paper_id`	No	Filter to a specific paper ID
`include_entities`	No	Include entity mentions
`include_bible_parallels`	No	Include the top-10 Bible verses semantically nearest to each result (Urantia → Bible).
`include_urantia_parallels`	No	Include the top-10 most-similar OTHER Urantia paragraphs for each result.

A4/5.0

Behavior5/5

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

Annotations already cover readOnly/idempotent/non-destructive, yet the description still discloses substantive behavior: the auto-mode fallback ladder (reference → exact phrase → every word → typo fixes → most words) and the set of possible `match` values plus `meta.didYouMean` and `meta.see` signals. That tells an agent how aggressively results were relaxed and how to interpret a partial match.

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 in the first clause, followed by mode semantics in a compact two-sentence block; nothing is filler. It is dense with inline code identifiers and quoted examples, which slows scanning slightly for an 11-parameter tool.

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 an output schema present, the description need not enumerate return values, and it covers the hardest part (mode semantics and match relaxation). It is silent on the include_* enrichment flags and the part_id/paper_id filters, but those are self-documenting in the schema and not essential to correct invocation.

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

Parameters4/5

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

Schema coverage is 100%, so the baseline is 3; the description earns more by explaining what `type: auto` actually resolves to and by showing that the query accepts structured references ("68:6.3", "103:2", "Paper 68", bare "68") alongside free text. The schema's own mode description is just a bare enum list, so this adds real meaning.

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?

States a specific verb and resource ("Keyword search across all paragraphs of the Urantia Papers"), which implicitly separates it from the sibling search.semantic tool. It never names the sibling explicitly, so the keyword-vs-semantic distinction is left to inference.

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

Usage Guidelines3/5

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

The description gives strong guidance on how to pick a mode (auto/and/or/phrase) and what auto does, but says nothing about when to use this tool rather than search.semantic or works.search. Usage relative to alternatives is only implied by the word "keyword".

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