Fastest path to a verified first run

Start with quickstart, pick the right mode, and then use generated references for commands, tools, workflows, extension, and skill packs.

Quickstart
first-run
npx opendevbrowser
opendevbrowser launch
opendevbrowser snapshot
opendevbrowser click "ref:submit"

Install and bootstrap

Choose the installation route that matches your operating model.

npx path

Best for first runs, local trials, and CI smoke checks.

npx opendevbrowser

npm global

Install once for repeated local workflows and shell scripts.

npm install -g opendevbrowser

manual package

Use for pre-release first-run simulation from a local tarball.

npm pack && npm install /path/to/opendevbrowser-<version>.tgz

First-run walkthrough

Three steps to complete an end-to-end run with explicit verification.

Step 1

Install runtime and extension prerequisites for the mode you need (managed, extension, or cdpConnect).

Step 2

Start daemon, verify extension handshake status, then launch/connect and capture a baseline snapshot before actions.

Step 3

Execute actions/workflows, then verify status, diagnostics, cookie policy results, and cleanup state for deterministic completion.

Command discovery and parity

Keep installed CLI help output aligned with the canonical docs references.

Help inventory

Use both command forms during onboarding validation to confirm parity:

npx opendevbrowser --help npx opendevbrowser help

First-run checklist

Follow the full local-package onboarding checklist for daemon, extension, and first-task verification.

Open Docs Index

Annotation

Capture UI notes, element context, and structured payloads for implementation handoff.

What it does

Annotate live interfaces, attach comments to selected elements, and export payloads plus screenshots for reproducible review.

How to run it

Run the annotate command in managed or extension mode, then validate screenshots and annotation payloads in output artifacts.

Troubleshooting preview

Operational friction is documented with explicit checks and recovery commands.

Readiness checks first

Start with status, handshake, and mode checks before executing actions or workflows.

Deterministic recovery

Follow command-level recovery sequences to isolate auth, relay, and target failures quickly.

Auth and cookie controls

Workflow runs can explicitly control session cookie behavior per execution.

No-auth runs

Use `--use-cookies=false` or policy `off` for open browsing and deal-hunting runs that do not require login.

Mixed runs

Use policy `auto` to attempt cookie injection and continue when cookies are unavailable or rejected.

Strict auth runs

Use policy `required`; failures return explicit `auth_required` with structured `cookieDiagnostics` details.

Community and support links

Use docs, repository issues, and release records for support workflows.

Repository

Source code, issues, and releases for implementation truth.

CLI reference

Command-level behavior, flags, and examples from canonical docs.

Troubleshooting

Recovery patterns, diagnostics, and mode-specific operational checks.
