nauro-core
Shared pure-Python library for the Nauro ecosystem. Provides parsing, validation, context assembly, and constants used by both the Nauro CLI and the remote MCP server.
Installation
pip install nauro-core
What's inside
decision_model: the PydanticDecisionmodel plus compiled regexes andparse_decision/format_decisionfor the Nauro markdown protocol (decision titles, metadata fields, section headers)constants: limits, thresholds, valid values, file paths shared across all Nauro surfacesparsing: pure markdown→data helpers such asextract_stack_summaryanddecisions_summary_lines(decision parsing lives indecision_model.parse_decision, which returns a validatedDecision)context:build_l0/build_l1/build_l2context assembly from pre-loaded files and parsed decisionsvalidation: structural screening, hash dedup, and BM25 retrieval of related decisions
Design principles
- No I/O: no filesystem, no network; callers inject pre-loaded data. Runtime dependencies are compute-only (BM25, parsing, validation); embeddings are an optional extra (
nauro-core[embeddings]) - Function injection: callers pass pre-loaded data (
files: dict[str, str],decisions: list[dict]); nauro-core never reads files or calls APIs - Import isolation: enforced via
import-linter, so nauro-core cannot import fromnauroormcp_server
Usage
from nauro_core import parse_decision, build_l0, compute_hash
# Parse a decision markdown file
decision = parse_decision(markdown_content, "042-use-s3.md")
# Build L0 context from pre-loaded files
context = build_l0(files={"state.md": state, "stack.md": stack}, decisions=decisions)
# Check for duplicate decisions
hash_val = compute_hash(title="Use S3 for storage", rationale="...")
