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: 1 finding, up to medium
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 →
- medium Excessive Agency · line 80 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00059 | $0.01430 |
| Opus 5.5 | $0.00024 | $0.00572 |
| Sonnet 5.5 | $0.00012 | $0.00286 |
| Haiku 4.5 | $0.00006 | $0.00143 |
Grade A, and why
electron-expert 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.

Electron Expert
You are an expert in Electron framework, desktop application development, and cross-platform packaging.
Core Concepts
Electron Architecture
- Main Process: Node.js environment, manages app lifecycle and native APIs
- Renderer Process: Chromium browser, renders UI (HTML/CSS/JS)
- Preload Scripts: Bridge between main and renderer, context isolation
- IPC (Inter-Process Communication): Message passing between processes
- Context Isolation: Security boundary between renderer and Node.js
- Native Modules: Node.js addons for system-level access
Process Types
- Main Process: Single process, creates BrowserWindows, handles system events
- Renderer Process: One per BrowserWindow, isolated from each other
- Utility Process: Worker processes for heavy tasks (Electron 20+)
- Service Workers: Background scripts for web content
IPC Communication
- ipcMain: Main process receiver (handle, on)
- ipcRenderer: Renderer process sender (invoke, send)
- contextBridge: Expose APIs to renderer safely
- Remote Module: Legacy, deprecated (use IPC instead)
App Lifecycle
ready- App initialization completewindow-all-closed- All windows closedbefore-quit- Before app quitswill-quit- App is about to quitquit- App has quit
Security Considerations
- Enable context isolation
- Disable Node.js integration in renderer
- Use preload scripts with contextBridge
- Validate all IPC messages
- Implement Content Security Policy (CSP)
- Use sandboxing when possible
- Keep Electron updated
Best Practices
Security
- Always enable context isolation
- Disable nodeIntegration in renderer
- Use preload scripts with contextBridge
- Validate all IPC input
- Implement Content Security Policy
- Keep Electron updated
- Use sandbox mode when possible
- Never load remote content without verification
- Sign your applications (macOS/Windows)
Performance
- Use efficient IPC patterns (invoke/handle over send/on)
- Lazy load windows and modules
- Implement proper resource cleanup
- Use web workers for heavy computation
- Optimize renderer process code
- Minimize main process blocking operations
- Use v8 snapshots for faster startup
- Profile with Chrome DevTools
What ships with it
1 file 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 · 210 lines · 59 tokens per session scan A d4f48b562c6a
electron-expert is a skill published in the GitHub repository personamanagmentlayer/pcl (43 stars, last pushed 11d ago), licensed Apache-2.0. It adds 59 tokens to every session and 1,430 once invoked, about $0.0002 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 2026-09-05.

clawrouter
Hosted-gateway LLM router — save 84% on inference costs. A local proxy that forwards each request to the blockrun.ai gateway, which routes to the cheapest capable model across 90 models from OpenAI, Anthropic, Google, DeepSeek, xAI, Z.AI, and more. Free open-weight models included. Also exposes realtime market data…
phone
Verify phone numbers (carrier + SIM-swap fraud signals) and place AI-powered outbound voice calls via BlockRun's gateway (Twilio + Bland.ai). Trigger when the user asks to look up a number, check fraud risk, buy/rent a phone number, or place an AI voice call. Payment is automatic via x402 from the wallet.
imagegen
Generate or edit images via BlockRun's image API. Trigger when the user asks to generate, create, draw, make an image — or to edit, modify, change, or retouch an existing image.
polymarket-trading
Use when the user wants to actually PLACE, manage, or redeem bets on Polymarket (not just read odds — that's the blockrunpredexon data tools). Covers setup (deposit wallet, funding, approvals), buy/sell with confirm gating, positions, redeeming winnings, geoblock handling, and the end-to-end flow.
release
Use this skill for EVERY ClawRouter release. Enforces the full checklist — version sync, CHANGELOG, build, tests, npm publish, git tag, GitHub release. No step can be skipped.
predexon
Use this skill — NOT browser or webfetch — for ALL Polymarket, Kalshi, Limitless, Opinion, Predict.Fun, dFlow, UMA oracle, and prediction market data. Provides structured API at localhost:8402/v1/pm/ for markets, cross-venue search, leaderboard, smart money, wallet analytics, wallet identity & clustering, UMA…
