Eight hand-authored Claude Code skills, free under MIT. The gateway tier from the Skill Locker catalog.
| Skill | What it does |
|---|---|
| Anti-Slop Checker | Detects AI-sounding phrases and patterns in any text and rewrites them to sound human. Context-calibrated for different registers (academic, legal, SaaS, ESL). |
| 3-Minute Email | Writes ready-to-send emails under 150 words from any situation description — picks the right framework (cold, follow-up, apology, request), enforces the ask, kills the throat-clearing. |
| 60-Second Bio | Generates platform-correct short bios (LinkedIn, X, Instagram, speaker intro, About page) from minimal input. Different rules for each platform. |
| Content Idea Machine | 20 specific, scroll-stopping content ideas with hooks, format recommendations, and a 5-day calendar — engineered for diversity across 5 content pillars, not 20 versions of the same idea. |
| Meeting Debrief | Extracts structured debriefs from messy meeting notes. Built around the one distinction summarisation tools fudge: decisions vs discussion. |
| Flashcard Generator | Turns any notes, article, or chapter into spaced-repetition flashcards optimised for long-term retention — not just question/answer pairs. |
| Sleep Optimisation Plan | Diagnoses your specific sleep problem and builds a prioritised protocol that targets the root cause — not generic "avoid screens before bed" advice. |
| Personal Brand Architect | Builds a complete positioning system — who you're for, what you stand for, and how to say it — not surface-level "just be authentic" advice. |
The last three are deliberately from non-developer domains (learning, health, personal brand) that the free/OSS Claude-skill ecosystem barely covers — so you can see the kind of skill the paid catalogue focuses on, not just the commodity ones.
Each skill includes its full SKILL.md and a versions/ directory showing iteration history.
| Skill | Paste this into Claude Code |
|---|---|
| Anti-Slop Checker | "Check this for AI tells and make it sound human: [paste your text]" |
| 3-Minute Email | "Write a follow-up email to a client who hasn't replied in a week about the project proposal." |
| 60-Second Bio | "Write me a LinkedIn bio — freelance UX designer, 8 years, ex-agency, now solo, working with fintech startups." |
| Content Idea Machine | "Give me 20 content ideas about [your topic] with hooks and a 5-day posting calendar." |
| Meeting Debrief | "Turn these messy meeting notes into decisions, action items, and owners: [paste notes]" |
| Flashcard Generator | "Make spaced-repetition flashcards from these notes: [paste notes or a chapter]" |
| Sleep Optimisation Plan | "I wake at 3am most nights and can't get back to sleep — build me a plan." |
| Personal Brand Architect | "Help me build my personal-brand positioning. I'm a [role] who wants to be known for [topic]." |
/plugin marketplace add miniminer-droid/skill-locker-free
/plugin install skill-locker-free@skill-locker-freeThat's it. The skills register automatically and trigger when relevant.
Each skills/*/SKILL.md file is a complete, installable Claude Code skill. To install one:
mkdir -p ~/.claude/skills/<skill-name>
cp plugins/skill-locker-free/skills/<skill-name>/SKILL.md ~/.claude/skills/<skill-name>/SKILL.mdRestart Claude Code if it's running. The skill triggers automatically when a relevant prompt appears.
Three reasons.
One: if the free skills are good, they're the most credible evidence that the paid skills (288 more across 33 pillars on skilllocker.ai) are also good. The free tier IS the proof of the bar.
Two: the Claude skills ecosystem is dominated by free open-source skills already. Holding the free tier closed would be both ungenerous and bad strategy. Free here, paid for the rest.
Three: these skills have been through real Karpathy-loop improvement cycles. They're not first drafts. Putting them under MIT means anyone can read the SKILL.md to see how a polished skill is structured, fork them to adapt to their own context, and learn from the iteration history in versions/.
Each skill went through this loop:
Look at skills/anti-slop-checker/versions/ for a concrete example of what each iteration added (ESL register handling, academic register calibration, etc.).
If these are useful, the paid Skill Locker catalog has 288 more across:
Open catalog dataset: skilllocker.ai/skills.json. Lifetime updates on every paid purchase.
MIT — read, use, fork, adapt, learn from. See LICENSE.
The catalog metadata at skilllocker.ai/skills.json is also free to read and build on. The paid SKILL.md files (the other 288) stay gated behind purchase, but the catalog identity and these 8 free skills are open.
~30 seconds. Free. No account. Every finding cites a rule and a line of evidence.
