Breaking Changes Python Packages

griffe

Signatures for entire Python programs. Extract the structure, the frame, the skeleton of your project, to generate API documentation or find breaking changes in your API.

dbt-plan

Catch breaking dbt schema changes before dbt run executes them: dropped columns, the downstream models and data tests they break, contract violations. Static analysis of compiled SQL, no warehouse connection. Like terraform plan, for dbt.

since-cutoff

Find which APIs of your pinned Python dependencies changed after your coding model's training cutoff, and give the agent short AGENTS.md / CLAUDE.md notes from a static API diff. No model calls, no API key. CLI, MCP server, Claude Code plugin, GitHub Action.

aexpy

AexPy /eikspai/ is Api EXplorer in PYthon for detecting API breaking changes in Python packages.

comfy-import-guard

Predicts and attributes ComfyUI custom-node import breakage caused by removals in comfy.* internals

jev-oas-sentinel

Catch breaking API behavior hidden in OpenAPI prose with deterministic checks and TypeSafe JEV System One semantic review.

bumpguard-mcp

Guard your dependency bumps: an MCP server that tells your AI agent which parts of YOUR code break when you upgrade a dependency, and verifies AI-written code against the installed API - static analysis, never runs third-party code.

breakproof

No-spec API break gate: fail PRs only on deleted routes, with caller proof. pipx install, 10s demo, GitHub Action included.

mcp-contract

Contract testing for MCP servers: snapshot your tool surface, then fail CI when a change would break the agents that depend on it. Classifies breaking vs additive vs routing (description) changes.

specshift

Detects, classifies, and optionally summarizes breaking changes in OpenAPI/Swagger, GraphQL, and Protobuf/gRPC contracts using AI

willitbreak

Show which breaking API changes in a dependency actually reach your call sites.

semapact

Open-source lifecycle governance for ODCS data contracts: schema evolution, breaking-change detection, version policy, GitOps, and Databricks Unity Catalog integration.

hound-watchdog

🐕 Hound watches the third-party APIs your code depends on and tells you exactly when — and where — a change will break you.

breakwatch

Breakwatch- OpenAPI Breaking Change Detector

delimit

Building your AI organization: shared records and handoffs, plus a merge gate for AI-written code with signed, replayable attestation. Works with Claude Code, Codex, Cursor, and Gemini CLI.
