Remote Cloud Environment

Setup notes and caveats for developing Kandev in ephemeral cloud VMs (Cursor Cloud, Codex, GitHub Codespaces, or similar sandboxed environments).

Runtime requirements

• mise — mise.toml at the repo root pins the developer toolchain (Go 1.26, Node.js 24, pnpm 9.15.9, golangci-lint 2.9.0, go-licenses 1.6.0, pre-commit, etc.).
• gcc / sqlite headers — required for CGO (SQLite FTS5). scripts/bootstrap-dev-env installs these on common Linux/macOS package managers when it has permission.
• Azure Repos PR creation (optional) — only needed when testing worktree.create_pr against Azure remotes outside the published Docker image:
  • Azure CLI (az) on PATH
  • DevOps extension: az extension add --name azure-devops
  • Auth: az login or export AZURE_DEVOPS_EXT_PAT=<pat>
  • The ghcr.io/kdlbs/kandev image ships gh, az, and the azure-devops extension preinstalled (see root Dockerfile).
  • Host routing table: apps/backend/internal/agentctl/AGENTS.md.

Provider prepare scripts should do auth + clone first, then run the shared bootstrap from the repo root:

scripts/bootstrap-dev-env

For E2E-capable environments:

scripts/bootstrap-dev-env --with-e2e

Generated files before typecheck

Before running make typecheck, you must generate two files that are gitignored:

node apps/web/scripts/generate-release-notes.mjs
node apps/web/scripts/generate-changelog.mjs

Without these, tsc fails with missing module errors for @/generated/release-notes.json and @/generated/changelog.json.

Running dev mode

make dev from the repo root builds the backend and starts both the Go backend (port 38429) and Vite frontend (port 37429). The CLI launcher sets KANDEV_DEBUG_DEV_MODE=true which activates the dev profile from profiles.yaml, enabling mock agent and other dev conveniences. No external services (database, message queue, Docker) are needed — SQLite is embedded and the event bus runs in-memory.

Key commands

All documented in the root Makefile:

• make dev — build + start backend + web (dev mode)
• make test — backend (Go) + web (vitest) + CLI tests
• make lint — golangci-lint + ESLint
• make typecheck — TypeScript type-checking across all apps
• make fmt — format all code (run before lint to avoid false positives)
• make test-e2e — Playwright E2E tests (requires make build-backend && make build-web first). Uses e2e/playwright.config.ts. 1000+ specs.

Firecracker / cloud-VM caveats

These apply to Cursor Cloud, Codex, and similar Firecracker-backed sandboxes:

• tool PATH: scripts/bootstrap-dev-env activates mise for its own process. New shells should run eval "$(mise activate bash)" or use a shell profile that activates mise so node, pnpm, go, golangci-lint, and pre-commit resolve from the pinned toolchain.
• First page load: make dev compiles pages on first visit via Turbopack — expect ~25 s for the initial load.
• CLI test flake: src/ports.test.ts > isPortInUse > returns false within the timeout when the host black-holes packets fails because 192.0.2.1 behaves differently inside Firecracker. This is a known environment-specific flake, not a code issue.
• Playwright browser installation: playwright install chromium hangs during zip extraction (Node.js io_uring incompatibility with the Firecracker kernel). Workaround: scripts/install-playwright-browsers.sh runs the install with a timeout, then falls back to extracting the already-downloaded zips with unzip. scripts/bootstrap-dev-env --with-e2e calls this automatically. System deps can be installed via playwright install-deps chromium.
