 - Onboarding: resolve CLI entrypoint when running via `npx` so gateway daemon install works without a build step.
 - Linux: auto-attempt lingering during onboarding (try without sudo, fallback to sudo) and prompt on install/restart to keep the gateway alive after logout/idle. Thanks @tobiasbischoff for PR #237.
 - TUI: migrate key handling to the updated pi-tui Key matcher API.
+- Logging: redact sensitive tokens in verbose tool summaries by default (configurable patterns).
 - macOS: prefer gateway config reads/writes in local mode (fall back to disk if the gateway is unavailable).
 - macOS: local gateway now connects via tailnet IP when bind mode is `tailnet`/`auto`.
 - macOS: Connections settings now use a custom sidebar to avoid toolbar toggle issues, with rounded styling and full-width row hit targets.

+## Tool summary redaction
+
+Verbose tool summaries (e.g. `🛠️ bash: ...`) can mask sensitive tokens before they hit the
+console stream. This is **tools-only** and does not alter file logs.
+
+- `logging.redactSensitive`: `off` | `tools` (default: `tools`)
+- `logging.redactPatterns`: array of regex strings (overrides defaults)
+  - Use raw regex strings (auto `gi`), or `/pattern/flags` if you need custom flags.
+  - Matches are masked by keeping the first 6 + last 4 chars (length >= 18), otherwise `***`.
+  - Defaults cover common key assignments, CLI flags, JSON fields, bearer headers, PEM blocks, and popular token prefixes.
