Deterministic Python Packages

navi-sanitize

Deterministic input sanitization for untrusted text — invisible characters, homoglyphs, and encoding tricks, handled before your code sees them. Zero dependencies, no ML. Python 3.12+.

fullbleed

Deterministic HTML/CSS to PDF for Python, Rust, Node.js, C# and browsers. MIT licensed. Reports, invoices, previews and compiled variable-data documents.

pyopenvba

Pure-Python reader/writer for VBA macros embedded in Excel / PowerPoint / Word / Access files. Zero dependencies, deterministic round-trip, safe on protected and signed projects.

parglare

A pure Python LR/GLR parser - https://igor.dejanovic.online/parglare/

wickra-gym

A Gymnasium-compatible, microstructure-aware backtest environment with O(1) steps: precompute the dataset to a fixed feature tensor once, then step() is a pure array index. Deterministic RL rollouts, recomputable byte-for-byte in ten languages.

archkeel

Archkeel checks architecture boundaries and declared changes in AI-assisted code.

wickra-synth

Deterministic synthetic market microstructure — OHLCV, order book, trades and funding from a single seed, byte-identical across ten languages.

sluicer

Turn any web page, or a whole site, into structured data, with no model in the loop: every record a page declares with where each value came from, fields learnt from one example and checked on every page, crawls, feeds and archives.

checkwash

Flags known patterns of weakened tests and CI checks in a Git diff.

bgts-context-engine

Deterministic code-graph context engine for AI coding agents - PostgreSQL + Apache AGE + pgvector, MCP & REST, no LLM in the loop.

calybris

Deterministic proof-carrying decision core with replay verification, WAL, and fixed-point budget proofs

pyshal

Turn your whole lab — hardware and software — into safe, typed, permission-gated tools for an AI agent.

purrdf

PurRDF — one RDF 1.2 engine, one behavior, in Rust, Python, WebAssembly and C. Deterministic BM25 full-text search, exact GeoSPARQL 1.1 and embedding kNN answered from SPARQL, in-process, over one dataset: the three jobs a triple store usually kept PostgreSQL beside it for. Plus native codecs, RDFC-1.0, SHACL, ShEx, entailment and GTS transport.

file-observer

Deterministic file observation for pipelines — one read-only pass over a directory emits a reproducible JSON manifest of every file's type, metadata, structure, and provenance.

detective-spec

Writes the behavioral contract for a Python function — every behavior pinned by a test, every question it cannot answer named

schliff

Deterministic quality scorer for AI agent instruction files — 8-dimension scoring with security, multi-format (SKILL.md, CLAUDE.md, .cursorrules, AGENTS.md), anti-gaming detection, zero dependencies

ailang-lang

AI-first, deterministic programming language for low-maintenance business software development.

cymatix-context

Same query, same answer: deterministic RAG for agents. Local-first: one SQLite knowledge store, no LLM call on the retrieval path, CLI + HTTP + MCP, and a know/miss contract on every response.

packvium

Deterministic 3D cartonization and bin packing for Python. Exact integer geometry, no dependencies.

cks-core

The single source of canonical truth — immutable, verifiable knowledge for humans and AI.

al-falak

Al-Falak is an offline, zero dependency and deterministic python library for Islamic astronomy, starting with precise prayer times and expanding into broader temporal calculations.

easeo

A deterministic SEO metadata library for content platforms. Generate canonical URLs, titles, descriptions, robots directives, Open Graph, Twitter Cards, and JSON-LD from content entities. One Rust core with Python, Node.js, and Rust APIs.

almanac-compute

Deterministic, verifiable ephemeris + geomagnetic computation — the physical numbers LLMs hallucinate, computed correctly and checked against NOAA & JPL.

keyross

Ready-to-use verifiers for your agent loop — official rules compiled into checks your agent must pass before it acts. Pinned, deterministic, replayable.
