Anti Slop is an open-source set of rules and agent skills for AI coding agents that filters generic AI-generated user interfaces, copy, and code without prescribing colors, fonts, layouts, or other visual styles. Its core contains 38 mandatory rules across Hard Gate, Purpose-Gate, and Quality Locks tiers; a Liveliness Toolkit with ENERGY, RHYTHM, and MOTION controls; a Design Read; and a mandatory four-part PASS/FAIL Delivery Gate. Task-specific skills are organized as separate SKILL.md folders and loaded additively, while a project’s DESIGN.md supplies the visual direction. The repository provides installation through the npx antislop-ai picker, the skills.sh-compatible npx skills add command, or a Claude Code marketplace plugin, with support for agents including Claude Code, Codex, Antigravity, OpenCode, Cursor, Gemini CLI, and Hermes.

DevAssure is an AI-powered software testing platform whose O2 agent reads code changes, maps potentially affected application flows, and validates them automatically, including through browser interactions based on plain-English expected behavior. It generates scriptless, self-healing acceptance tests and reports results for pull requests.

Impeccable is an open-source design skill for AI coding agents, developed by pbakaus. It provides a shared design vocabulary with 23 commands, including init, shape, critique, audit, polish, harden, animate, typeset, layout, and live. The init command gathers product and design context into PRODUCT.md and DESIGN.md files, while other commands review, plan, modify, or refine a frontend project. Its CLI and browser extension run 61 deterministic detector rules for common AI-generated frontend design problems without an LLM or API key; it also supports LLM-based critique checks. The live command provides browser-based visual iteration, and the package can be installed from a project root with npx impeccable install.

Abide is an open-source CLI and hook/plugin system that enforces project instructions for coding agents. It compiles AGENTS.md, CLAUDE.md, and other instruction files into a local rubric, then checks each edit and completed turn against the applicable rules. For each check, it sends the rule and changed code to Jev, TypeSafe's decision model, which returns a probability rather than free-form text; violations above the configured threshold produce a repair request for the agent. It supports Claude Code, Codex, and OpenCode, and also provides commands for auditing existing files, checking uncommitted changes, replaying sessions, reporting rule activity, calibrating rules against git history, and measuring latency and cost. The rubric is stored in .abide/rubric.json, while changed lines are sent to TypeSafe under the user's key with zero data retention requested. The project is licensed under MIT.

Procoder is a Go binary that provides commit gates and quality controls for AI coding agents. It checks formatting, tests, linting, secrets, Git and repository hygiene, CI and infrastructure hygiene, and documentation health, while treating unavailable checks as failures. Its tools can be run by the agent, and lifecycle hooks can invoke checks at fixed points; the binary computes and reports findings while the agent reviews and applies changes rather than modifying repository files itself. A lessons loop records escaped bug classes for future checks, and adapters support Claude Code and other agents that use integrations such as AGENTS.md. It has no runtime dependencies and is distributed as a single binary.
