Agent Operating Rules (read first)

Failure taxonomy — classify every failure before acting. Escalate cheapest-first; never skip a rung or repeat one:

• transient (network blip, flaky): retry at most 2×.
• code (your bug, wrong path, bad arg): fix, then retry.
• tool-usage-gated (you called a working tool wrong): fix the call, not the tool. Cheapest fix — try this before assuming the tool is broken. Example: chrome-devtools new_page with isolatedContext opens a cookieless context; instead use list_pages → select_page to drive the existing authenticated tab.
• tooling-gated (the tool's source is genuinely broken): diagnose before fixing — verify it's actually broken (read the code, reproduce). If broken, spawn a fix-it subagent to patch + rebuild it, then retry. Do NOT stop.
• infra (CI runner, emulator boot timeout): report it; do not try to "fix" someone else's infrastructure.
• human-gated (only when no automated path exists): emit ONE precise instruction for the human, mark the task BLOCKED, and continue all other automatable work. Never re-attempt across turns.

Diagnose before fixing: Before patching or replacing any tool, confirm it is actually the cause. Copilot burned 39h assuming chrome-devtools-mcp was broken — it wasn't (it already drives the authenticated default context via browser.defaultBrowserContext()/browser.pages()). A 3-minute diagnostic subagent would have caught this.

Known gated steps:

• Play Console API-access grant to the service account — was the blocker; now granted (publish run 26662900471 succeeded, AAB on internal track, versionCode 19). One-time path if re-needed: Play Console → Setup → API access → link GCP project opencode-mobile-deploy → grant playstore-deploy@opencode-mobile-deploy.iam.gserviceaccount.com Admin/Release-manager.
• Add internal testers (Play Console → Internal testing → Testers): the genuinely human-gated residual. Google's anti-automation blocks CDP-controlled Chrome sign-in, so this UI step needs a human (or a real, non-CDP browser session).

Stop discipline: If a tool returns the same error 3× (or no new artifact/commit is produced across several turns), STOP. Print a BLOCKED summary with the single human action needed. A vague "please do X and let me know" that leaves you idle is worse than a clean stop — don't do it.

Overview

React Native / Expo mobile client for opencode. Connects to an opencode server instance via HTTP + SSE for real-time updates.

Repo: dzianisv/opencode-mobile (standalone, not part of opencode monorepo) Package name: cc.agentlabs.opencode

Key Patterns

• SSE for real-time: The events.ts store connects to /global/event and dispatches to other stores
• Fire-and-forget sends: sendMessage posts to the API but doesn't await response; SSE events drive all UI updates
• Session status: Derived from session.status events (idle/busy/retry) + last part type for status text
• Markdown: react-native-marked wrapped in our own Markdown component with custom CodeBlock (copy button). Designed to be swappable/publishable later.

Style Guide

• Prefer const over let
• Avoid else statements, use early returns
• Prefer single-word variable names
• Avoid try/catch where possible
• Avoid any type
• Use Bun APIs where applicable (for scripts, not in RN runtime)

Running

npm install
npx expo start        # Expo dev server
npx expo run:android  # Android emulator

Connecting

Run opencode serve --hostname 0.0.0.0 --port 4096 on your machine, then add a connection in the app with your machine's local IP and port 4096.

Dev server: 100.108.64.76:4096 (Tailscale, hostname openclaw-dev-1)

Android Emulator (local dev)

IMPORTANT: Do NOT install SDK/AVD on the system disk. Use the external disk.

export ANDROID_HOME=/Volumes/Dzianis-3/macbook2020/android-sdk
export ANDROID_AVD_HOME=/Volumes/Dzianis-3/macbook2020/android-avd
export GRADLE_USER_HOME=/Volumes/Dzianis-3/macbook2020/gradle-cache
export PATH="$ANDROID_HOME/platform-tools:$ANDROID_HOME/emulator:$PATH"

emulator -avd test -no-window -no-audio -no-boot-anim -gpu swiftshader_indirect -no-snapshot -port 5554
adb wait-for-device
# Wait for boot:
timeout 120 bash -c 'while [ "$(adb shell getprop sys.boot_completed 2>/dev/null)" != "1" ]; do sleep 2; done'

SDK location: /Volumes/Dzianis-3/macbook2020/android-sdk (API 34, arm64-v8a system image). AVD location: /Volumes/Dzianis-3/macbook2020/android-avd. Gradle cache: /Volumes/Dzianis-3/macbook2020/gradle-cache (or symlink from /Volumes/GradleCache/gradle-home).

CUA Smoke Test (E2E via Vision LLM)

The script scripts/android-cua-smoke.py drives the emulator via ADB using a vision model loop (screenshot → LLM → action → repeat).

Running locally

source ~/.env.d/azure-openai.env
python3 scripts/android-cua-smoke.py --model gpt-5.4 --include-xml

Azure OpenAI credentials

The correct Azure AI Services endpoint (with actual deployments) is:

• Endpoint: https://info-mjnxtt51-eastus2.cognitiveservices.azure.com
• Env file: ~/.env.d/azure-openai.env
• Available vision models: gpt-5.4, gpt-5.2, gpt-5.1, gpt-4.1

Warning

: The vibe-dev-ai.cognitiveservices.azure.com resource has NO deployments (only a model catalog). Do NOT use it for inference. Always use info-mjnxtt51-eastus2.

API notes for gpt-5.x models

• Use max_completion_tokens (NOT max_tokens) — the older param is rejected.
• Use AzureOpenAI client from the openai Python SDK with api_version="2024-08-01-preview".
• Vision works: pass image_url with data:image/png;base64,... in user message content array.

CI

GitHub Actions workflow: .github/workflows/cua-smoke.yml Secrets required: AZURE_OPENAI_API_KEY, AZURE_OPENAI_ENDPOINT (already set on dzianisv/opencode-mobile).

Triggers: Runs on push to main (with path filters) AND on v* tags (releases).

When to run CUA test

MANDATORY: Run the CUA smoke test before any merge to main or release:

1. Before merging a PR that touches src/**, app/**, or scripts/android-cua-smoke.py
2. After creating a release tag — CI runs it automatically
3. When debugging UI issues — run locally with --include-xml for richer context

If the CUA test fails, do NOT merge or release until fixed.

Secrets Management

All project secrets are stored in Bitwarden vault under folder opencode-mobile.

Use the bitwarden-cli skill to read/write secrets. Quick reference:

# Unlock (needs BW_PASSWORD in env or ~/.bitwarden_credentials)
source ~/.bitwarden_credentials
export BW_SESSION=$(bw unlock --passwordenv BW_PASSWORD --raw)
bw sync --session "$BW_SESSION"

# Get a secret
bw get notes "EXPO_PUBLIC_SENTRY_DSN" --session "$BW_SESSION"

# List all secrets in the folder
FOLDER_ID=$(bw list folders --session "$BW_SESSION" | jq -r '.[] | select(.name=="opencode-mobile") | .id')
bw list items --session "$BW_SESSION" | jq --arg f "$FOLDER_ID" '[.[] | select(.folderId==$f) | {name}]'

Secrets stored in vault:

• EXPO_PUBLIC_SENTRY_DSN — Sentry ingest DSN (embedded in APK at build time)
• SENTRY_AUTH_TOKEN — sentry-cli upload token (source maps, releases)
• SENTRY_ORG — vibetechnologies
• SENTRY_PROJECT — opencode-mobile

These same secrets are set as GitHub Actions secrets on dzianisv/opencode-mobile for CI builds.

Do NOT store secrets in .env files committed to the repo. .env is gitignored — local copy only.

Chrome DevTools (Browser Automation)

The project uses @vibebrowser/chrome-devtools-mcp from github.com/dzianisv/chrome-devtools-mcp. It runs an MCP server over HTTP/SSE, allowing multiple agents to connect remotely.

No --remote-debugging-port needed. The daemon discovers Chrome via --autoConnect (reads DevToolsActivePort file). Port is discovered automatically.

Driving an authenticated session: The daemon connects to your real Chrome profile (authenticated). To act on a logged-in page, use list_pages → select_page on the existing tab. Do not pass isolatedContext to new_page — that opens a cookieless context that cannot see your login. (Verified: the MCP code already uses browser.defaultBrowserContext(); logged-out sessions come from misuse, a profile/--user-data-dir mismatch, or Google's anti-automation block — not a tool bug.)

Local Copilot CLI config (in .github/copilot-mcp.json or IDE MCP settings):

{
  "chrome-devtools": {
    "type": "remote",
    "url": "http://localhost:9333/mcp",
    "enabled": true
  }
}

Starting the daemon:

chrome-devtools start --autoConnect --port 9333

Google Play Console

• Developer account: VIBE TECHNOLOGIES, LLC (ID: 8842655543970815326), Google login vibeteaichnologies@gmail.com. The /u/N/ index is NOT stable — if a console URL bounces to accept-terms/create-developer-account you're on the wrong Google account (e.g. dzianisvv@gmail.com hits a ToS gate); use the developer-account chooser to reach VIBE.
• Rebrand (2026-05-30): package renamed ai.opencode.mobile → cc.agentlabs.opencode. A NEW Play Console app is required (package IDs can't be renamed) — creation NOT yet confirmed (do not record an app ID until verified from a live dashboard URL). First AAB upload for a new app must be MANUAL via UI (Google blocks the Developer API for a new app's first release); CI can publish updates after. CI packageName already = cc.agentlabs.opencode.
• Legacy app (orphaned): ai.opencode.mobile, app ID 4975545755653045321 — published v19 to internal track (run 26662900471), superseded by the rebrand.
• Track: Internal testing (no review required, up to 100 testers)
• Service account: playstore-deploy@opencode-mobile-deploy.iam.gserviceaccount.com (account-level API access already granted)
