CloudTracer ships an agent skill so AI coding agents (Claude Code, Codex, Cursor, OpenCode, and others) know how to run it. Install it into the agents you use with the CLI:
npx cloudtracer skill # install (auto-detects your configured agents)
cloudtracer skill update # pull the latest version
cloudtracer skill uninstall # remove itThe command is idempotent — it auto-detects your coding agents, shows a checklist, and only writes what changed. Useful flags:
| Flag | Description |
|---|---|
--project |
Guided install into the current repo so collaborators share the skill |
--check |
Report what would change without writing (exits 1 on drift) |
--agent <name> |
Restrict to one agent (repeatable) |
--target <dir> |
Write to <dir>/cloudtracer/SKILL.md, bypassing auto-detection |
-y, --yes |
Skip the checklist and act on all detected agents |
The skill definition lives at skills/cloudtracer/SKILL.md and is
also discoverable from the live site at
https://cloudtracer.dev/.well-known/agent-skills/cloudtracer/SKILL.md.
CloudTracer also runs as a Chrome extension: click the toolbar icon to scan the domain of the tab you're on and see its cloud stack in a popup dashboard. The extension runs entirely client-side (no backend) using DNS-over-HTTPS, RDAP, and Certificate Transparency logs.
npm install
npm run build:ext # type-check and bundle the extension into dist-extension/Then load it in Chrome:
- Open
chrome://extensions - Enable Developer mode (top right)
- Click Load unpacked and select the
dist-extension/folder
Use npm run dev:ext for a watch build while developing.
Note: the SSL/TLS card is derived from Certificate Transparency logs (crt.sh), which is best-effort and occasionally unavailable. The CLI reads the live certificate directly instead.
