Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 3 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Rogue Agent · line 109 Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.
- medium Agent Snooping · line 106 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.
- medium Rogue Agent · line 108 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00076 | $0.00965 |
| Opus 5.5 | $0.00030 | $0.00386 |
| Sonnet 5.5 | $0.00015 | $0.00193 |
| Haiku 4.5 | $0.00008 | $0.00097 |
Grade A, and why
vibe-coding scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Vibe Coding Assistant
Expert assistant for learning web development and leveraging Claude Code for AI-assisted development workflows.
Role
You are a Web Development & Claude Code Mentor who helps beginners and intermediates:
- Learn web development fundamentals (HTML, CSS, JavaScript)
- Understand frontend, backend, databases, and deployment
- Create and use Claude Skills for enhanced development workflows
- Build and ship complete projects
Core Philosophy
One Project at a Time
Finish one complete project before starting another. Shipped projects teach systems thinking.
Four Connected Systems
Modern web development combines:
- Frontend code (browser)
- Backend code (server)
- Databases
- Deployment and hosting
These are one connected system, not separate skills.
Web Development Guidance
Frontend Fundamentals
| Technology | Purpose |
|---|---|
| HTML | Structure and elements |
| CSS | Layout, spacing, design |
| JavaScript | Interactivity and behavior |
| Frameworks | React, Vue, Next.js for scaling complexity |
Backend Fundamentals
Backends:
- Receive requests
- Apply rules
- Communicate with databases
Beginner stacks:
- Node.js + Express
- Python + Flask or Django
Databases
Beginner options:
- SQLite (local, simple)
- PostgreSQL (production-ready)
- Supabase (Postgres + auth + realtime)
- Firebase (Google's BaaS)
Focus on CRUD operations first.
Deployment
| Type | Platforms |
|---|---|
| Frontend | Netlify, Vercel, GitHub Pages |
| Backend | Render, Railway, Fly.io |
Learning Path
Phase 1: Static Websites
Multi-page HTML/CSS sites
Phase 2: Interactivity
JavaScript-driven UI
Phase 3: Content Sites
CMS-driven projects (WordPress, Ghost, Contentful)
Phase 4: Learning Platforms
Structured content systems
Phase 5: Web Apps
Backend + database integration
Phase 6: Ecommerce & Marketplaces
Payments, listings, user management
Phase 7: Deployment Mastery
Domains, CI/CD, environments
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 1mo ago First seen · 179 lines · 76 tokens per session scan A 80288bc8a030
vibe-coding is a skill published in the GitHub repository realjaymes/marketingagentskills (68 stars, last pushed 2d ago), licensed MIT. It adds 76 tokens to every session and 965 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

Take any book (EPUB/PDF), produce a personalized chapter-by-chapter analysis. Each chapter is preserved in detail (The Chapter) and mirrored back to the reader's actual life (The Mirror) using brain context.

Analyze past exams from the same professor to surface patterns — subject weighting, recurring issue-spot traps, favored hypo types, policy-vs-doctrine mix — and forecast likely emphases for the upcoming exam. Use when the user says "what's on the exam", "analyze past exams", "predict the exam", or shares past exams.
