build_cross_spec_suite
Build Cross-Spec Suite
Assemble the normative requirements for one procedure across a spec AND the specs it normatively references — a procedure like registration or handover is never described in a single document. Returns a cited suite plan; feed the requirement_ids to generate_tests. Args: spec_base: The anchor spec, e.g. "23502" or "38331" keyword: The procedure/topic, e.g. "registration", "handover", "authentication" include_references: Also pull matching clauses from specs this one references (default: True) limit: Max requirements in the plan (default: 20, max: 50)
Read only Idempotent
Input schema 
{'type': 'object', 'title': 'build_cross_spec_suiteArguments', 'required': ['spec_base', 'keyword'], 'properties': {'limit': {'type': 'integer', 'title': 'Limit', 'default': 20}, 'keyword': {'type': 'string', 'title': 'Keyword'}, 'spec_base': {'type': 'string', 'title': 'Spec Base'}, 'include_references': {'type': 'boolean', 'title': 'Include References', 'default': True}}}
Output schema 
{'type': 'object', 'title': 'build_cross_spec_suiteOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
diff_spec_versions
Diff Spec Versions
Diff two versions of a specification at the NORMATIVE level: which requirements were added, removed, or reworded. Not a textual diff — a clause that merely moved page or was recased counts as unchanged. Args: spec_base: Spec identity without the version, e.g. "38331" or "23501" from_version: Older version label, e.g. "j20" (default: the second-newest in the corpus) to_version: Newer version label, e.g. "j30" (default: the newest in the corpus) obligation: Only report changes at this strength — "must", "must_not", "should", "should_not", "may" limit: Max requirements to list per bucket (default: 25)
Read only Idempotent
Input schema 
{'type': 'object', 'title': 'diff_spec_versionsArguments', 'required': ['spec_base'], 'properties': {'limit': {'type': 'integer', 'title': 'Limit', 'default': 25}, 'spec_base': {'type': 'string', 'title': 'Spec Base'}, 'obligation': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'Obligation', 'default': None}, 'to_version': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'To Version', 'default': None}, 'from_version': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'From Version', 'default': None}}}
Output schema 
{'type': 'object', 'title': 'diff_spec_versionsOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
generate_tests
Generate Conformance Tests
Generate a cited, runnable conformance test that verifies one normative requirement. The test is grounded in the requirement sentence plus its surrounding clause from the corpus, and every test cites the spec, section and page it enforces. If the requirement is not testable (boilerplate, scope text), the generator abstains rather than inventing a test. Args: requirement_id: The requirement's id, as shown by get_requirements target: "pytest" for a runnable Python test module, or "gherkin" for a reviewable .feature file (default: pytest)

get_document_content

get_relationship_graph
Get a relationship graph centered on a specification, expanding N hops. Returns JSON with nodes and edges suitable for graph visualization. Each node includes title, series, working group, and reference counts. Each edge includes source, target, reference type, and count. Args: spec_number: Center specification number depth: Number of hops to expand (1-3, default: 1) reference_type: Filter by type - "normative", "informative" (optional)
Input schema

get_requirements
Get Requirements
List normative requirements (RFC 2119 / BCP 14 "shall/should/may" statements) extracted from specifications, each cited back to its source clause.

{'type': 'object', 'title': 'get_requirementsOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
get_rfc_lineage
RFC Lineage
An RFC's revision history. RFCs are immutable — an RFC is never revised, it is obsoleted or updated by a *different* RFC — so this Obsoletes/Updates graph, not a version diff, IS its change history. Use it to find out whether an RFC you depend on has been superseded. Args: rfc: The RFC, e.g. "7231", "rfc7231" or "RFC 7231"
Read only Idempotent
Input schema 
{'type': 'object', 'title': 'get_rfc_lineageArguments', 'required': ['rfc'], 'properties': {'rfc': {'type': 'string', 'title': 'Rfc'}}}
Output schema 
{'type': 'object', 'title': 'get_rfc_lineageOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
get_schema_definitions
Get Schema Definitions
Look up formal, machine-checkable structure defined in the specifications: ASN.1 types (3GPP RRC/NAS message grammars) and JSON Schema / OpenAPI models (5G Service Based Interfaces). Prefer this over prose search when the question is about a message's *structure* — field names, types, ranges, optionality. The definition is returned verbatim from the spec, so it is exact rather than recalled. Args: name: Type or schema name, e.g. "RRCSetup", "MeasConfig", "SmContextCreateData" spec_number: Restrict to a spec, e.g. "38.331" kind: "asn1", "openapi" or "json_schema" limit: Maximum definitions to return (default: 10, max: 25)
Read only Idempotent
Input schema

Output schema 
{'type': 'object', 'title': 'get_schema_definitionsOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
get_series_overview
Get an overview of all specification series with document counts, reference statistics, and working group assignments.
Input schema 
{'type': 'object', 'title': 'get_series_overviewArguments', 'properties': {}}
Output schema 
{'type': 'object', 'title': 'get_series_overviewOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
get_spec_dependents

Output schema 
{'type': 'object', 'title': 'get_spec_dependentsOutput', 'required': ['result'], 'properties': {'result': {'type': 'string', 'title': 'Result'}}}
get_spec_metadata
Get enriched metadata for specifications with filtering. Args: spec_number: Filter by spec number (partial match) series: Filter by series (e.g., "26" for 26.xxx codecs) working_group: Filter by working group (e.g., "SA4") doc_class: Filter by document class - "TS" or "TR" limit: Maximum results (default: 50)
Input schema 
{'type': 'object', 'title': 'get_spec_metadataArguments', 'properties': {'limit': {'type': 'integer', 'title': 'Limit', 'default': 50}, 'series': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'Series', 'default': None}, 'doc_class': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'Doc Class', 'default': None}, 'spec_number': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'Spec Number', 'default': None}, 'working_group': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'title': 'Working Group', 'default': None}}}

get_spec_references
Get all specifications referenced by a given spec. Args: spec_number: Specification number (e.g., "23.501", "26.230") reference_type: Filter by type - "normative", "informative", "inline" (optional)
