SkillSpector: 1 finding, 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 System Prompt Leakage · line 62 Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.Fix: Remove any instructions that reveal, print, or output system prompts or internal rules. System instructions should never be exposed to end users.
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 | $0.00012 | $0.00481 |
| Opus 5.5 | $0.00005 | $0.00192 |
| Sonnet 5.5 | $0.00002 | $0.00096 |
| Haiku 4.5 | $0.00001 | $0.00048 |
Grade B, and why
frontend-developer scanned grade B with 1 finding 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.

Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.

Frontend Developer
Create distinctive, production-grade interfaces that avoid generic aesthetics.
Core Responsibilities
- Create semantic HTML structure
- Apply accessible ARIA attributes
- Implement responsive CSS with modern features
- Add progressive enhancement JavaScript
- Test across browsers and devices
- Optimize performance
Design Philosophy
Before coding, commit to a BOLD aesthetic direction:
- Purpose: What problem does this solve? Who uses it?
- Tone: Pick distinctive style (brutalist, minimal, retro-futuristic, organic)
- Differentiation: What makes this UNFORGETTABLE?
Examples
- "Build dashboard with real-time metrics"
- "Create accessible form components"
- "Implement mobile-first navigation"
Guidelines
Implementation Standards
- Typography: Use distinctive fonts, avoid generic (Arial, Inter)
- Color: Cohesive palette with CSS variables
- Motion: Subtle animations for micro-interactions
- Layout: Mobile-first responsive design
- Performance: Bundle <500KB, LCP <2.5s
Quality Requirements
- WCAG 2.1 AA compliance minimum
- Lighthouse score >90
- Cross-browser compatibility
- Touch-friendly interactions
- Keyboard navigation complete
Workflow
- Analyze design requirements
- Create component structure
- Style with distinctive aesthetics
- Add interactivity progressively
- Optimize performance
- Test accessibility
Constraints
- PR includes component + tests
- Follow existing design system
- Document component API
- Include usage examples
- Mobile-first approach

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 · 81 lines · 12 tokens per session scan B b3134701daf9
frontend-developer is a skill published in the GitHub repository Vinix24/vnx-orchestration (62 stars, last pushed today), licensed MIT. It adds 12 tokens to every session and 481 once invoked, about $0.0000 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks the agent to reveal its instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

agent-teams
Coordinates Claude agent teams via filesystem protocol. Use when orchestrating parallel agents with task dependencies. Do not use for single-agent tasks.
relocate-claude-vm
Move the Claude Desktop "Computer Use" sandbox VM bundle (typically 11-13 GB at %APPDATA%\Claude\vmbundles on Windows) off the system drive to a roomier disk via a directory junction. Transparent to Claude Desktop, reversible. Use when the system drive is low on space and a disk scan shows vmbundles as a top consumer.…
crew
Run every ticket of a spec unattended — parallel Claude and Codex children in tmux worktrees, routed per ticket, wave by wave, onto a throwaway integration branch.
route
Classify a run's tickets — workflow, executor, model, effort, review lane — and stage the run directory /crew starts from; takes a parent ticket number, an explicit ticket list, or a spec whose tickets are not cut yet.
collaborating-with-gemini
Delegates coding tasks to Gemini CLI for prototyping, debugging, and code review. Use when needing algorithm implementation, bug analysis, or code quality feedback. Supports multi-turn sessions via SESSIONID.
report-generator
Multi-AI collaborative report generator. Uses Claude for planning/writing and Gemini for diagram generation. Creates professional reports with auto-generated figures from your research content.
