Add a pnpm workspace with a `packages/installer` package (`@sentry/ai`)
that provides a single CLI for installing the Sentry plugin into any
supported AI coding assistant: Claude Code, Codex, Cursor, and Grok.
The CLI (built on citty) exposes an `install` subcommand. By default it
shows an interactive selector pre-selecting the detected agents;
`--no-interactive`/`--yes` skips the prompt and installs every detected
agent — used for CI and unattended runs.
Each agent is a self-contained harness implementing a common strategy
interface — detect, isInstalled, canInstall, install — so adding a new
agent is just another module. System access (shell, fs, platform,
homedir) is injected through a SystemDeps seam, keeping every harness
unit-testable without side effects.
Behavior:
- Already-installed agents update in place rather than erroring or
no-opping: Cursor pulls, Grok/Claude use their update commands, Codex
re-adds (idempotent; it has no update command).
- Claude refreshes its marketplace index before installing, since a fresh
CLI ships a stale index that cannot resolve the plugin.
- canInstall gates prerequisites (Cursor needs git) and reports a clear
skip instead of a cryptic failure.
- One agent failing does not abort the rest, and the CLI exits non-zero
if any selected agent failed or was blocked.
- Cross-platform: binary detection uses where/which per OS, Cursor is
located via its per-OS install path, and git paths are quoted for
Windows spaces.
Distribution:
- rolldown bundles the npm package (deps external).
- fossilize builds standalone Node SEA binaries; --hole-punch drops
non-English ICU data to cut the download ~30%.
CI:
- A smoke-test matrix (Linux, macOS, Windows) installs the real agent
CLIs and runs the installer non-interactively, asserting the plugin
lands for every detected agent.
