gstack

Open Pstack is an unofficial, plugin-based workflow kit that brings Lauren Tan's pstack to Claude Code and Codex. It gives coding agents engineering rules, task-specific workflows, focused skills, and small local tools rather than providing a new model or hosted service. Its main poteto-mode workflow reads a task, selects an appropriate workflow, learns how the existing system works, compares designs when needed, favors small changes, and can use multiple models to challenge important decisions. It runs the code and checks behavior as a user would instead of stopping at passing tests, then can continue through review and continuous integration to prepare a pull request. Additional skills cover system explanation, architectural decisions, competing implementations, design interrogation, verification-skill creation and maintenance, pull-request supervision, and reflection. The repository supports installation as a Claude Code or Codex plugin and shares the same skill set between those applications. It is distributed under the MIT license and tracks the upstream pstack project while adapting its skills for Claude Code and Codex.

Skills for Real Engineers is an open-source collection of small, composable agent skills by Matt Pocock for disciplined software development with Claude Code, Codex, and other coding agents. The skills support requirements clarification, project-language setup, test-driven development, debugging, code review, specification, planning, triage, and codebase surveys. The collection includes skills such as `/grill-me` and `/grill-with-docs`, which question the user about a proposed change before implementation, and a setup skill that configures an issue tracker, ticket labels, and documentation storage for a repository. It can be installed as a managed Claude Code plugin or copied into a project as editable files through the `skills` installer; the skills are intended to work with any model and can be adapted by the user.

Everything Claude Code is a Claude Code plugin and toolkit containing configurable agents, skills, slash commands, rules, hooks, contexts, MCP server configurations, scripts, and tests for AI-assisted software development. Its agents delegate tasks such as planning, code review, security review, testing, and build-error resolution. Skills define workflows including test-driven development, security review, continuous learning, and verification; hooks run on Claude Code tool or session events to load and save context, suggest compaction, and evaluate sessions; and rules provide persistent guidance for security, coding style, testing, Git workflow, delegation, and performance. Node.js scripts support Windows, macOS, and Linux and detect a project's preferred package manager from environment settings, project configuration, package.json, lock files, or global configuration. The repository can be installed as a Claude Code plugin or copied into Claude configuration directories manually. It includes a Node.js test suite and is distributed under the MIT license.

Cangjie Skill is an open-source pipeline that distills methodologies from books, long-form videos, podcasts, interviews, and courses into callable AI Agent Skills rather than summaries. The resulting skills package evidence, examples, executable steps, and usage boundaries so coding agents can invoke the extracted methodology. Its capability-bundle workflow extracts stable capability cards and metadata before compiling installable output. It supports a single router-style Skill or a compact pack containing a router and promoted standalone Skills. The unified local toolchain includes diagnostics, compilation, output replanning, incremental updates, repair, rollback, evaluation, and benchmarking, while content-addressed preprocessing, source diffs, impact analysis, transactional patches, snapshots, and edit detection support controlled evolution. The repository also provides a standalone installation package for DeepSeek Harness.

Agent Skills is an open-source collection of engineering workflows for AI coding agents, developed by Addy Osmani. It packages senior-engineering practices into skills covering the development lifecycle: defining specifications, planning, incremental implementation, testing and debugging, constraints, code review, web-performance auditing, code simplification, and shipping. Slash commands such as /spec, /plan, /build, /test, /review, and /ship activate the corresponding workflows, while skills can also activate automatically based on the work being performed. The /build workflow can generate a plan and implement its tasks in an approved pass, while retaining test-driven verification, individual commits, and pauses for failures or risky steps. It can be installed with the skills CLI or integrated into supported coding agents including Claude Code, Cursor, Codex, Copilot, and Cline.
