pylife

a general library for fatigue and reliability

24K 199 43

chaostoolkit

Chaos Engineering Toolkit & Orchestration for Developers

15K 2K 207

surpyval

A Python package for survival analysis. The most flexible survival analysis package available. SurPyval can work with arbitrary combinations of observed, censored, and truncated data. SurPyval can also fit distributions with 'offsets' with ease, for example the three parameter Weibull distribution.

caliper-eval

Run your real agent with and without your skills, MCPs, and rules. See which ones actually help, and what they cost in tokens. Supports Claude Code, Codex, Pi, and Hermes.

5K 209 23

baldur-framework

Self-healing reliability layer for Python — circuit breaker, retry, and fallback behind a single decorator. Framework-agnostic core with Django, FastAPI, Flask, and Celery adapters.

krkn-lib

Chaos and resiliency testing tool for Kubernetes with a focus on improving performance under failure conditions. A CNCF sandbox project.

5K 509 248

failecho-autoreport

When a tool or model call fails, your agent learns what fixed it for other agents, or that nothing has. Plugins for Claude Code and OpenCode, an MCP proxy, a Python wrapper. Open source, metadata only.

avo

Observable AI agent runtime uniting Claude, ChatGPT, and Gemini subscriptions with multi-tier failover down to local Ollama. Replayable SQLite ledger.

failecho-mcp

3K 2 0

fmdtools

System Resilience Modelling, Simulation, and Assessment in Python

3K 60 19

failproofai-sdk

Observability and enforcement for AI agent harnesses. Capture every run and runtime reliability with policy enforcement.

3K 5K 504

redress

Policy-driven failure handling for Python services.

2K 45 2

operon-ai

Biologically Inspired Architectures for EpiAgentic Control

2K 33 3

firstpass

The verification layer for LLM serving — your check runs on every answer before it ships, with a signed, tamper-evident receipt for each decision and a distribution-free bound on wrong answers served. Proof over prediction.

2K 1 1

freshctx

Pre-action evidence revalidation for AI agents. Detect stale reasoning before agents write, send, update, or delete.

2K 4 0

mnfst

Manifest SDK for Python. See every API call your app makes, heal the ones that fail, and know what will break next.

2K 0 0

tracelint

A deterministic linter for agent runs — reads the execution trace and flags structural bugs (ignored errors, schema violations, loops) with evidence. No LLM judge.

2K 11 2

lockstep-evidence

Does what's actually installed match the lockfile? Runtime dependency drift, not a commit-time CVE scan

2K 1 0

gpt-computer-assistant

Build autonomous AI agents in Python.

2K 8K 748

evalint

Lint an LLM eval set: reliability, wrong-answer items, near-duplicates, and droppable cases.
