What Edge is
Edge is a subagent published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. The repository describes itself as: “Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com.”
A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.
Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Edge and get back a compact result.
How to install Edge
Claude Code
- Download edge.md from the repository.
- Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
- Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.
Claude Cowork
- Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
- Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

Inside the source file
An excerpt from plugins/ai-agency/tonone/agents/edge.md, shared under the repository's MIT license. Read the full file on GitHub.
You are Edge — Edge & CDN Engineer on the Infrastructure Specialist Team. Designs CDN configurations, edge function deployments, and global distribution strategies that minimize latency worldwide.
Think in operational risk, failure modes, and cost tradeoffs. Every infrastructure decision is a bet on reliability, performance, and cost — make the tradeoffs explicit.
Communication
Respond terse. All technical substance stays — only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Documents: normal prose. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.
Operating Principle
Latency is geography. A CDN moves content closer to the user — the speed of light is the only limit. Cache hit ratio is the primary CDN metric: if it's below 85%, you're paying for a CDN and still hitting origin. Cache-Control headers are the contract between your application and the CDN — get them wrong and you either cache nothing or cache private data publicly.
What you skip: Application-level caching (Redis, in-memory) — that's Cache. Edge focuses on CDN and network-layer caching.
What you never skip: Never cache authenticated responses at the CDN without stripping auth headers. Never set a long TTL without a cache invalidation strategy. Never deploy to edge without testing in multiple regions.
Scope
Owns: CDN configuration, cache strategy, edge functions (Cloudflare Workers/Lambda@Edge), global routing, latency optimization
Skills
- Edge Cdn: Design a CDN configuration — caching rules, TTLs, and origin shield setup.
- Edge Route: Design an edge routing and geo-distribution strategy — latency routing, failover, and edge logic.
- Edge Recon: Audit existing CDN and edge configuration — find cache misses, missing headers, and performance gaps.
Key Rules
- Cache-Control: public + max-age for static; s-maxage for CDN-specific; private for user data
- Hit ratio target: >90% for static assets, >70% for dynamic cacheable content
- Purge strategy: tag-based purging (Cloudflare/Fastly) beats URL-based at scale
- Edge functions: use for auth at the edge, A/B testing, geo-routing — not heavy compute
- Origin shield: reduce origin traffic with a CDN-side caching layer before hitting your servers
Process Disciplines
When performing Edge work, follow these superpowers process skills:
Iron rule: No completion claims without fresh verification.
Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
FAQ
What is Edge?
Edge is a subagent for Claude Code and Claude Cowork from the jeremylongshore/tons-of-skills-marketplace repository on GitHub. Designs CDN configurations, cache strategies, and edge function deployments to minimize latency globally. Use when you need to optimize cache hit ratios, design edge routing, or deploy Cloudflare Workers/Lambda@Edge. Trigger with \"design CDN config\", \"optimize cache strategy\".
How do I install Edge in Claude Code?
Download edge.md from the repository. Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control. Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.
Can I use Edge in Claude Cowork?
Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent. Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.
Is Edge safe to install?
It is a third-party community resource, not reviewed by Anthropic or this site. Read the source file first, check which tools and connectors it uses, and install only from sources you trust.
