This repository is a skill factory for AI coding agents, enabling teams to systematically build, refine, and evaluate reusable agent skills so hard-won prompting and workflow knowledge can become scalable productivity.
Skill Claude CodeCodex
A planning method for turning a large or abstract software idea into a local project direction and a prioritised backlog. A backlog is a list of work still to be done, ordered by importance and dependencies.
Skill Claude CodeCodex
A guided process for turning one unclear software request into a written design and acceptance criteria. It uses evidence from the project, step-by-step questions, and comparisons between possible approaches.
Skill Claude CodeCodex
An independent, evidence-based review process for code changes, commits, or local pull-request differences.
Skill Claude CodeCodex
A code-to-request converter that turns HTTP endpoint code into ready-to-run `curl` commands and raw HTTP/1.1 examples.
Skill Claude CodeCodex
Read-only CLI for exploring PostgreSQL, MySQL, and SQLite databases. Use this skill whenever a task needs reliable database facts, including schema details, sample records, read-only query results, or code-model verification against actual database structure. Do not use for writes, migrations, data fixes, bulk…
Skill Claude CodeCodex
A skill for applying design-review findings after confirming each design decision with the user. It also handles direct fixes and updates the design documentation and readiness status.
Skill Claude CodeCodex
A separate, evidence-based review process for a file named design.md, which usually describes a software design.
Skill Claude CodeCodex
Neural web search for official documentation, API references, and structured source retrieval with text extraction. Use for precise, source-first research when you need high-quality results or extracted page content. For breaking news or real-time sentiment, use grok-search instead.
Skill Claude CodeCodex
Generate git commit messages and submit commits. Use when preparing commit messages, deciding split commits, or running git commit.
Skill Claude CodeCodex
Create and manage git worktrees for isolated parallel work. Use this skill whenever the user mentions worktrees, wants to work on multiple branches simultaneously, needs to test changes without affecting their main working directory, or asks about creating/managing/removing worktrees. Also trigger when users want to…
Skill Claude CodeCodex
Real-time web research and live synthesis with sources. Use when the question depends on freshness, community chatter, X/Twitter dynamics, breaking updates, or broad multi-source summaries. Prefer this over source-first search when you need fast situational awareness. Prefer exa-search instead for official docs, API…
Skill Claude CodeCodex
Fetch Hacker News stories, comments, and users. Use when the user says "Hacker News", "HN", "Y Combinator", "tech news digest", "top stories on HN", or asks to pull/aggregate tech news from HN.
Skill Claude CodeCodex
A generator for a high-level design document, a concise overview of a system intended for human review. It turns a detailed low-level design into a scannable document with diagrams and tables.
Skill Claude CodeCodex
A tool guide for turning Markdown—a plain-text document format—into a standalone HTML web page. The output can include navigation, summaries, highlighted key points, and document checks.
Skill Claude CodeCodex
A decision-support method based on Charlie Munger's mental models and 25 common ways people misjudge situations. Mental models are thinking tools used to examine a problem from different angles.
Skill Claude CodeCodex
A process for revising a PRD, or product requirements document, after a review has identified problems or suggestions.
Skill Claude CodeCodex
Analyze PRD documents for logic gaps, boundary issues, and technical feasibility before development starts. Focus on business logic closure and architectural reasonability, not implementation details.
Skill Claude CodeCodex
A pre-development review for a product requirements document, or PRD—a written description of what a product should do. It checks the business process, missing edge cases, and whether the proposed technical approach is feasible.
Skill Claude CodeCodex
A price-checking tool for products sold by major Chinese online marketplaces, including JD, Taobao, Tmall, and Pinduoduo. It gathers current price information without requiring a marketplace login.
Skill Claude CodeCodex
Guide for creating and optimizing AI agent skills. Use when the user wants to create a new skill, improve an existing skill, review skill quality, or understand skill authoring best practices. Covers skill structure, content guidelines, common patterns, and anti-patterns.
Skill Claude CodeCodex
Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
Skill Claude CodeCodex
Create new AI agent skills from scratch or optimize existing skills through systematic workflows. Use when the user wants to create a new skill, improve an existing skill's quality or performance, run evaluations to test a skill, or optimize a skill's triggering accuracy. Provides step-by-step workflows with…
Skill Claude CodeCodex
A skill for creating new coding-agent skills and auditing or improving existing ones. It works with skill instruction files called SKILL.md and their supporting references or assets.
Skill Claude CodeCodex
A skill for carrying out tasks described in project specification files such as tasks.md and design.md, while recording progress with checkboxes.
