At a glance

- Starting the Opik local development environment
- SKILL.md covers Quick Start, Modes, URLs and Build Commands, plus 3 more sections
- Calls docker, mvn and npm
- Rebuilding just the backend or frontend after a change
What it does
This skill uses a single dev-runner script that handles full restarts, daily starts without rebuilding, stopping everything, and backend-only restarts for faster iteration, serving the frontend on one local port in standard mode and a different port in backend-only mode, with the backend API and its health check on a fixed port.
An opt-in Platform mode, off by default, runs the Comet EM/Platform stack alongside Opik behind a single-origin nginx proxy for Opik-team members only, auto-detecting sibling comet-backend and comet-react checkouts and building comet-backend under a detected JDK 17 or 21 while Opik itself stays on JDK 25. Troubleshooting commands cover verifying the stack, checking for a port conflict, and a clean stop-then-restart.
When your agent uses it
- Starting the Opik local development environment
- Rebuilding just the backend or frontend after a change
- Running Opik connected to the Comet Platform stack for internal testing
Example prompts
- “Start the Opik dev environment for frontend work.”
- “Rebuild just the backend after my change.”
- “Run Opik in Platform mode connected to comet-backend.”
Requirements
- Docker
- JDK 17/21 for Platform mode, JDK 25 for Opik
What it can do on your machine
Read from SKILL.md and the folder at commit f217a86. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
dockermvnnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use docker and npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Opik Local Dev Environment loads about 734 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 124 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Quick Start
./scripts/dev-runner.sh --restart # First time / full rebuild
./scripts/dev-runner.sh --start # Daily start (no rebuild)
./scripts/dev-runner.sh --stop # Stop everything
./scripts/dev-runner.sh --verify # Check statusModes
| Mode | Command | Frontend | Use When |
|---|---|---|---|
| Standard | --restart | localhost:5174 | Frontend work, full-stack |
| BE-only | --be-only-restart | localhost:5173 | Backend-focused, faster rebuilds |
| Platform (EM) | PLATFORM_ENABLED=true ./scripts/dev-runner.sh --restart | localhost:9100 | Opik-team only: run Opik connected to the Comet Platform |
Platform (EM) mode — Opik-team only
PLATFORM_ENABLED=true runs the Comet EM/Platform stack (comet-backend +
comet-react, auto-detected sibling checkouts) alongside Opik behind a
single-origin nginx proxy, with Opik in comet mode authenticating/resolving
workspaces via comet-backend. Off by default — Standard/BE-only dev is
unaffected. comet-backend builds under a detected JDK 17/21; Opik still uses JDK 25.
PLATFORM_ENABLED=true ./scripts/dev-runner.sh --restart # then also --start/--stop/--verify
