debug

A troubleshooting guide for NanoClaw's container system, where the assistant runs in an isolated environment. It explains the host-to-container file mounts, log locations, environment variables, and authentication or session issues.

In plain words
What is it for?
Use it to investigate container startup failures, missing files, authentication problems, broken session resumption, and agent execution errors. It points to host logs and the corresponding container directories.
Why use it?
It gives you a map of where failures can occur when the assistant, container, mounts, or login process stops working. Knowing which side owns a log or file makes diagnosis faster.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade D, and why

debug scanned grade D with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

--dangerously-skip-permissions cannot be used with root/sudo privileges

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

NanoClaw Container Debugging

This guide covers debugging the containerized agent execution system.

Architecture Overview

Host (macOS)                          Container (Linux VM)
─────────────────────────────────────────────────────────────
src/container-runner.ts               container/agent-runner/

    │ spawns container                      │ runs Claude Agent SDK
    │ with volume mounts                   │ with MCP servers
    │                                      │
    ├── data/env/env ──────────────> /workspace/env-dir/env
    ├── groups/{folder} ───────────> /workspace/group
    ├── data/ipc/{folder} ────────> /workspace/ipc
    ├── data/sessions/{folder}/.claude/ ──> /home/node/.claude/ (isolated per-group)
    └── (main only) project root ──> /workspace/project

Important: The container runs as user node with HOME=/home/node. Session files must be mounted to /home/node/.claude/ (not /root/.claude/) for session resumption to work.

Log Locations

Log Location Content
Main app logs logs/nanoclaw.log Host-side WhatsApp, routing, container spawning
Main app errors logs/nanoclaw.error.log Host-side errors
Container run logs groups/{folder}/logs/container-*.log Per-run: input, mounts, stderr, stdout
Claude sessions ~/.claude/projects/ Claude Code session history

Enabling Debug Logging

Set LOG_LEVEL=debug for verbose output:

# For development
LOG_LEVEL=debug npm run dev

# For launchd service (macOS), add to plist EnvironmentVariables:
<key>LOG_LEVEL</key>
<string>debug</string>
# For systemd service (Linux), add to unit [Service] section:
# Environment=LOG_LEVEL=debug

Debug level shows:

  • Full mount configurations
  • Container command arguments
  • Real-time container stderr

Common Issues

1. "Claude Code process exited with code 1"

Check the container log file in groups/{folder}/logs/container-*.log

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Subscribe to this mod's changes

debug is a skill published in the GitHub repository ShinyStar307/nano---Openclaw (5 stars, last pushed 5mo ago), licensed MIT. It adds 40 tokens to every session and 2,933 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it D with 2 findings (asks for root, recursive force delete). It is 92% identical to debug, differing in 32 lines, and is treated as a copy.
