❓ Questions about NJ-Kit and Claude Code skills · tap to open
A free, open-source Claude Code plugin: one working method and 41 skills. Every skill ends in a script gate that prints PASS or FAIL. MIT licence, by Nader Alzghoul.
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.
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.
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. You can install both. Compare ↑
Any agent that reads SKILL.md files can use the skill folders directly, with no installer. The plugin route is for Claude Code.
No. An independent project by Nader Alzghoul, not affiliated with or endorsed by Anthropic.
Yes. MIT licence.
No. Copy one skill folder into ~/.claude/skills/ and it works on its own.
Yes. Arabic and English are both first-class, RTL included.
Yes. Nothing is tied to one machine.
- ⚙️ Set the variables a skill names:
NJ_PLUGIN_ROOT, JIRA_BASE_URL, PORTAL_URL…
- 🏠 Or keep the defaults under your home folder.
🎙️ NJ-Narration · the right voice, no noise around it
In the plugin since 2.0.2. A skill that picks and cleans a narrator's voice, and prints PASS or FAIL for every step.
- 🎯 Scout a voice that fits the character. Describe age, origin, accent and mood; the skill turns it into numbers and measures licensed voices against them.
- 🛠️ Engineer it once, at the source. The reference clip is cleaned once and every line is voiced once. No re-voicing until one sounds right.
- 🩹 Heal noise without cutting words. Hiss before or after a sentence is removed, and a gate checks the speech itself is untouched.
One example (made-up data, to show the shape of the output; not a real measurement, not a real person):
BRIEF narrator, woman, 40 to 55, calm, British English, dry room
TARGET pitch 165 to 210 Hz, 130 to 150 words a minute, little echo
SOURCES public domain or written consent only, one clip per speaker
REFERENCE CLIP (the one you will clone)
REF-QUALITY FAIL 0.6 s of room tone at the start
# cleaned once, word-safe, then measured again
REF-QUALITY PASS
EACH GENERATED LINE (one take)
TAKE-QUALITY PASS
VOICE-EDGE-NOISE FAIL 1.9 s of hiss after the last word
# cleaned without touching the speech
VOICE-EDGE-NOISE PASS speech samples identical
NEXT the top 3 voices go to your ear. You decide.
Install: the same two lines as NJ-Kit (Plugin ↑). nj-narration is one of the 24 plugin skills; after installing, say "use nj-narration".
Plugin only: /plugin install nj-kit@nj-kit. Any other agent that reads SKILL.md: copy the folder nj-plugin/skills/nj-narration.
Honest note: NJ-Narration ships no voices and no audio samples. It includes no voice engine and picks none for you: you bring a licensed voice and an engine you are allowed to use. The numbers decide what reaches your ear; your ear decides last.
