Setup skill fixes:
- Run QR auth in foreground with long timeout, not background
- Replace fragile message-based registration with DB group sync lookup
- Personal chats: ask for phone number instead of querying empty DB
- Consolidate trigger word + security model + channel selection into one step
- Remove `timeout` shell command (unavailable on macOS), use Bash tool timeout
- Query 40 groups, display 10 at a time, support name lookup
requiresTrigger support:
- Add requiresTrigger field to RegisteredGroup type and DB schema
- Skip trigger check when requiresTrigger is false (for solo/personal chats)
- Main group still always processes all messages (unchanged)
Agent-browser visibility:
- Append global CLAUDE.md to non-main agent system prompts via SDK
- Add browser tool docs to global and main CLAUDE.md
- Update skill description to be broader (not just "web testing")
- Reference agent-browser.md in root CLAUDE.md key files

Always log detailed input/output/stderr on error (not just in verbose
mode), and stop truncating stderr/stdout in structured log fields.

- Fall back to text result when success subtype has no structured_output
- Treat outputType 'message' without userMessage as 'log' with warning
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Rename status→outputType, responded/silent→message/log for clarity
- Remove scheduled task special-casing: userMessage now sent for all contexts
- Update schema, tool, and CLAUDE.md descriptions to be clear and
non-contradictory about communication mechanisms
- Use full tool name mcp__nanoclaw__send_message in docs
- Change schedule_task target_group to accept JID instead of folder name
- Only show target_group_jid parameter to main group agents
- Add defense-in-depth sanitization and error callback to exec() in shutdown
- Use "user or group" consistently (supports both 1:1 and group chats)

* fix: wire up queue processMessagesFn before recovery to prevent silent message loss
recoverPendingMessages() was called after startMessageLoop(), which meant:
1. Recovery could race with the message loop's first iteration
2. processMessagesFn was set inside startMessageLoop, so recovery
enqueues would fire runForGroup with processMessagesFn still null,
silently skipping message processing
Move setProcessMessagesFn and recoverPendingMessages before startMessageLoop
so the queue is fully wired before any messages are enqueued.

* feat: structured agent output to fix infinite retry on silent responses (#113)
Use Agent SDK's outputFormat with json_schema to get typed responses
from the agent. The agent now returns { status: 'responded' | 'silent',
userMessage?, internalLog? } instead of a plain string. This fixes a
critical bug where a null/empty agent response caused infinite 5-second
retry loops by conflating "nothing to say" with "error".
- Agent runner: add AGENT_RESPONSE_SCHEMA and parse structured_output
- Host: advance lastAgentTimestamp on both responded AND silent status
- GroupQueue: add exponential backoff (5s-80s) with max 5 retries for
actual errors, replacing unbounded fixed-interval retries

- Fix startup recovery running before WhatsApp connects, which could
permanently lose agent responses by advancing lastAgentTimestamp
before sock is initialized
- Add 5s retry on container failure so messages aren't silently dropped
until a new message arrives for the group
- Use `container stop` in shutdown instead of raw SIGTERM to CLI wrapper,
ensuring proper container cleanup
- Replace unnecessary dynamic imports with static imports in processTaskIpc
- Guard JSON.parse of DB-stored last_agent_timestamp against corruption
- Validate MAX_CONCURRENT_CONTAINERS (default 5, min 1, NaN-safe)

Add per-group container locking with global concurrency limit to prevent
concurrent containers for the same group (#89) and cap total containers.
Fix message batching bug where lastAgentTimestamp advanced to trigger
message instead of latest in batch, causing redundant re-processing.
Move router state, sessions, and registered groups from JSON files to
SQLite with automatic one-time migration. Add SIGTERM/SIGINT handlers
with graceful shutdown (SIGTERM -> grace period -> SIGKILL). Add startup

Session type, isScheduledTask flag, ContainerConfig.env, getTaskRunLogs,
GroupQueue.isActive.

WhatsApp reconnections called startMessageLoop/startSchedulerLoop/
startIpcWatcher and setInterval again without stopping the previous

* Fix potential memory DoS via unbounded container output
Add CONTAINER_MAX_OUTPUT_SIZE (default 10MB) to limit accumulated
stdout/stderr from container processes. Without this limit, a malicious
or buggy container could emit huge output leading to host memory
exhaustion.
Changes:
- Add configurable CONTAINER_MAX_OUTPUT_SIZE in config.ts
- Implement size-limited output buffering in runContainerAgent
- Log warnings when truncation occurs
- Include truncation status in container logs

Previously, lastTimestamp was unconditionally advanced after each message,
even if processMessage failed. This caused transient errors to permanently
drop messages since they would never be retried.
Now the cursor only advances after successful processing, implementing
at-least-once delivery semantics. On failure, the loop breaks and the
failed message will be retried on the next poll iteration.

ASSISTANT_NAME was interpolated directly into a regex without escaping.
If the name contained regex metacharacters (e.g., @A.*), the trigger
would match unintended patterns. This adds escapeRegex() to properly
escape special characters before building the TRIGGER_PATTERN.

* Add secure mount allowlist validation
Addresses arbitrary host mount vulnerability by validating additional
mounts against an external allowlist stored at ~/.config/nanoclaw/.
This location is never mounted into containers, making it tamper-proof.
Security measures:
- Allowlist cached in memory (edits require process restart)
- Real path resolution (blocks symlink and .. traversal attacks)
- Blocked patterns for sensitive paths (.ssh, .gnupg, .aws, etc.)
- Non-main groups forced to read-only when nonMainReadOnly is true
- Container path validation prevents /workspace/extra escape
https://claude.ai/code/session_01BPqdNy4EAHHJcdtZ27TXkh
* Add mount allowlist setup to /setup skill
Interactive walkthrough that asks users:
- Whether they want agents to access external directories
- Which directories to allow (with paths)
- Read-write vs read-only for each
- Whether non-main groups should be restricted to read-only
Creates ~/.config/nanoclaw/mount-allowlist.json based on answers.
