Drift Detection Python Packages

alibi-detect

Algorithms for outlier, adversarial and drift detection

ccdrift

A check for silent changes in Claude Code's prompt caching, Haiku use, settings, context and hooks, read from your local session logs

docguard-cli

Audit and enforce canonical project documentation for AI-assisted development. Detect drift, validate specs, and brief agents. Part of the Guard family with TestGuard and WebSec Validator.

contexer

Contexer keeps the important engineering decisions behind your software current and available to every coding agent.

doc-lattice

A deterministic, offline traceability engine for design and production documentation. Tracks derives_from edges across markdown, flags drift when upstream content changes, and gates it in CI.

yigraf

A truth maintenance system for AI coding agents — one graph over code, intent, plan, and the why: every belief justified, anchored to the code it concerns, and flagged when it stops holding. pip install yigraf

mcpsafetywarden

MCP servers expose tools with no information about what they actually do at runtime. mcpsafetywarden sits between your agent and any MCP server, profiling tool behavior, blocking destructive calls, and running active security audits before you trust them in a workflow.

capymoa

CapyMOA does efficient machine learning for data streams in Python. CapyMOA is a toolbox of methods and evaluators for: classification, regression, clustering, anomaly detection, semi-supervised learning, online continual learning, and drift detection for data streams.

replimap

AWS Infrastructure Intelligence Engine — scan brownfield AWS accounts, map every dependency, and turn ClickOps into import-ready Terraform. 100% local.

cognifity-verdict

Open-source LLM observability and drift detection for AI apps

cognifity-verdict-eval

Open-source LLM observability and drift detection for AI apps

cognifity-verdict-inspect

Open-source LLM observability and drift detection for AI apps

vmware-harden

AI-native VMware compliance and baseline enforcement (CIS, vSphere SCG, 等保 2.0, PCI-DSS) — sibling to vmware-* skill family

toolprint

What your agent's tool surface costs, and what it can do. Offline MCP assessment: context cost, capability risk, and definition drift.

frouros

Frouros: an open-source Python library for drift detection in machine learning systems.

mcp-placard

Static analysis and drift detection for MCP servers: enumerate the surface a server exposes to an agent, classify every tool's blast radius (R0-R5), hash it, and fail CI when it escalates. Never invokes a tool.

driftcheck-py

Detect version drift between docs and toolchain files (README vs rust-toolchain.toml etc.)

pycyclops

A toolkit for evaluating and monitoring AI models in clinical settings

popmon

Monitor the stability of a Pandas or Spark dataframe ⚙︎

checkowners

Align CODEOWNERS with reality

hookrecon

Find Stripe payments that never reached your database — read-only CLI, zero install: uvx hookrecon check

servseal

Behavioural attestation for deployed language models: is the model you serve the model you validated? 1 KB/position fingerprints that catch silent sampling filters, quantisation and template bugs.

agentassert-abc

Runtime behavioral contracts for AI agents: define YAML contracts, check adapter outputs, and raise explicit contract violations. Agent Behavioral Contracts (ABC).

fleet-sensor-baseline

Which units differ from their cohort, and what changed on this unit across time. Sits above bmc-sensor-audit, holding the machine list and the capture history, so a sensor that quietly went absent on a few trays in a large rack surfaces as a finding. Exit codes are the CI interface.
