- Mark as experimental (not just unofficial)
- Add region and safeSearch tool parameters (from DDG schema)
- Add plugin config example for region/safeSearch defaults
- Document auto-detection order (100 = last)
- Note SafeSearch defaults to moderate
- Verified against extensions/duckduckgo/src/
- Apply normalizeEnvVarKey({ portable: true }) before security
filtering, matching the established pattern in env-vars.ts.
Rejects non-portable key names (spaces, special chars) that
would produce invalid plist/systemd syntax.
- Isolate existing tests from the developer's real ~/.openclaw/.env
by providing a temp HOME directory, preventing flaky failures
when the test machine has a populated .env file.
When building the gateway install plan, read and parse
~/.openclaw/.env (or $OPENCLAW_STATE_DIR/.env) and merge those
key-value pairs into the service environment at the lowest
priority — below config env vars, auth-profile refs, and the
core service environment (HOME, PATH, OPENCLAW_*).
This ensures that user-defined secrets stored in .env (e.g.
BRAVE_API_KEY, OPENROUTER_API_KEY, DISCORD_BOT_TOKEN) are
embedded in the LaunchAgent plist (macOS), systemd unit (Linux),
and Scheduled Task (Windows) at install time, rather than
relying solely on the gateway process loading them via
dotenv.config() at startup.
Previously, on macOS the LaunchAgent plist never included .env
vars, which meant:
- launchctl print did not show user secrets (hard to debug)
- Child processes spawned before dotenv loaded had no access
- If the same key existed in both .env and the plist, the stale
plist value won via dotenv override:false semantics
Dangerous host env vars (NODE_OPTIONS, LD_PRELOAD, etc.) are
filtered using the same security policy applied to config env
vars.
