A free, open-source Claude Code plugin: one working method and 41 skills, each ending in a PASS or FAIL script gate. - What are Claude Code skills? A skill is a folder with a SKILL.md file of instructions, plus any scripts it needs. Claude Code reads each skill's description and loads the skill when a task matches it. - What is a gate? A script at the end of a skill that checks the result and prints PASS or FAIL. On FAIL, the skill makes one fix and runs the gate again. - The method: analyse, find the skill, plan, execute, gate, review. - Skill groups: method and agents (9), QA and Jira (5), documents and writing (6), audio and video (3), bundled with the kit (17). - How is it different from anthropics/skills? Anthropic's repository is its public collection of Agent Skills. NJ-Kit is an independent kit built around one working method, and every one of its skills ends in a PASS or FAIL script. Both can be installed together. - Arabic: Arabic and English are both first-class, right-to-left included, with an Arabic proofreading skill. - Licence and price: MIT, free. - NJ-Narration (`nj-narration`, in the plugin since 2.0.2): a skill that scouts a narrator voice from a character brief, engineers it once, and heals noise before or after a line without cutting words; PASS or FAIL gates; ships no voices and no audio samples ## Related - [Nader Alzghoul, QA Automation Engineer](https://nj-burrito.github.io/): the author - [Profile-Wrap](https://nj-burrito.github.io/Profile-Wrap/): open-source LinkedIn post manager - [QA-Wrap](https://nj-burrito.github.io/QA-Wrap/): browser extension that turns a test session into a bug report
