Module reference 

The query_syntax texts (spec/surface/README.md §4; 5.1): the manual (QUERY_SYNTAX, { section: "all" }), its chapters (query_syntax_section, one per ## heading of QUERY_SYNTAX_SECTIONS) and the card (QUERY_SYNTAX_CARD, what {} returns). A condensed distillation of docs/query-language.md. Byte for byte the reference’s packages/core/src/mcp/reference.ts — tests below compare every text with it when the monorepo is present, and others parse every example the texts show.

Constants

QUERY_SYNTAX

The agent-facing OQX syntax reference the query_syntax tool returns for { section: "all" } (and for {} through 5.0).

QUERY_SYNTAX_CARD

The card query_syntax {} returns (5.1): the grammar skeleton, the names rule and the engine names per kind, the handles, the consumers, follow in two lines, the examples agents reach for first, the chapter names. Byte for byte the reference’s QUERY_SYNTAX_CARD (a test below compares the two).

QUERY_SYNTAX_SECTIONS

The manual’s chapters (spec/surface §4 query_syntax, 5.1): one (slug, heading) per ## heading of QUERY_SYNTAX, in order — the section argument’s names. Byte for byte the reference’s QUERY_SYNTAX_SECTIONS (a test below checks every pair against its source).

QUERY_SYNTAX_SECTION_NAMES

The section names a caller may pass: every slug, then all (the whole manual).

Functions

query_syntax_section

One chapter of the manual (5.1): the lines from ## <heading> up to (not including) the next ## heading or the end, trailing blank lines dropped, one trailing newline. "all" is the whole manual; an unknown slug is None. The reference’s querySyntaxSection, rule for rule.
