Watch this toolREADMELoading documentation…# Heystack plugins Plugins for [Heystack](https://heystack.dev) — observability + security for AI apps — so your coding agent can **set up** Heystack, **investigate** incidents, and **manage** your workspace from your editor. ## Install (Claude Code) ``` /plugin marketplace add heystack-hq/heystack-plugins /plugin install heystack@heystack ``` Then run `/mcp` to sign in with Heystack and pick your organization. Try: *"list my Heystack apps"*, *"why is /checkout failing since the last deploy?"*, or *"set up Heystack in this project and verify it's receiving data"*. ## What you get **`heystack`** (recommended) — the all-in-one plugin: - **Hosted MCP server** at `https://mcp.heystack.dev/mcp` (connected with `?toolsets=core,manage`): app health, search traces & logs in plain English, open and explain traces, session stories and replays, issues and crashes with the suspect release, gen-AI usage & cost, a one-call incident dossier (`heystack_investigate`); plus apps, ingest keys, sampling/replay config, alert rules and app care. Team administration (members, invites, access tokens, audit) and read-only SQL stay opt-in: edit the plugin's `.mcp.json` URL to `?toolsets=core,manage,team` (or `advanced`). Actions that grant access, mint keys or tokens, or send data to an external URL always ask for your confirmation. Sign in with Heystack (OAuth) — no keys to paste. Full reference: https://heystack.dev/docs/mcp - **`heystack-setup` skill** — detects the runtime (Next.js, Cloudflare Workers/Agents, Node, browser, Android) and wires the correct `@heystack/otel` entry or OTLP path; with the MCP server it creates the app and key itself and verifies data arrives with `heystack_verify_setup`. - **`heystack-investigate` skill** — the investigation loop: overview → dossier → traces/sessions → fix in code → verify; when to change issue status or create alerts; never destructive without your confirmation. **`heystack-setup`** — the setup skill on its own (no MCP server), kept for existing installs: `/plugin install heystack-setup@heystack`. **`heystack-timeline`** (optional, requires `heystack`) — `/plugin install heystack-timeline@heystack`. Hooks that show your coding agent's steps on the Heystack investigation timeline. - **Opt-in:** nothing is recorded until you switch on **Show my coding-agent steps** in the Heystack console (Settings, Profile). Turning it off deletes the recorded steps. - **Privacy:** only the file path of an edit and the one-line description of a shell command are sent. Never file contents, diffs, command lines, prompts or tool output. Absolute paths transit TLS to Heystack and are reduced to repo-relative paths before storage; paths outside the project are dropped. - **Best-effort:** Claude Code gives session-end hooks about 1.5 seconds, so the closing call may not land; the investigation then just goes idle. A shell command without a description records no step. - Requires write access on your Heystack connection; it reuses the `heystack` plugin's MCP sign-in. ## Other agents - Cursor / VS Code / Codex / Gemini CLI / Claude.ai connect to the same MCP URL — see https://heystack.dev/docs/mcp for one-click links and commands. - The skills are plain [Agent Skills](https://agentskills.io) files and are also served raw at https://heystack.dev/heystack-setup.md and https://heystack.dev/heystack-investigate.md. The root `plugin.json` / `mcp.json` / `skills/` follow the cross-vendor [Agent Plugins](https://agent-plugins.org) layout. - Every docs page is available as Markdown: https://heystack.dev/llms.txt ## Layout ``` .claude-plugin/marketplace.json # Claude Code marketplace (plugins: heystack, heystack-setup, heystack-timeline) plugins/heystack/ # all-in-one: .mcp.json + skills/ plugins/heystack-setup/ # skill-only (legacy) plugins/heystack-timeline/ # optional hooks: edit paths + command purposes plugin.json · mcp.json · skills/ # Agent Plugins (cross-vendor) layout of the `heystack` plugin ``` Source of truth for the skills is the [heystack monorepo](https://github.com/heystack-hq/heystack) (`packages/setup-skill`, `packages/investigate-skill`); this repo is a mirror.
