nanoclaw-fleet: Skill for Claude Code

.claude/skills/debug/SKILL.md

debug is a skill for Claude Code from thmtz/nanoclaw-fleet. It costs 40 tokens per session (2,931 once invoked), scanned D, a copy of debug, MIT.

A troubleshooting skill for NanoClaw's container-based agent system. Containers are isolated environments where the agent runs; the guide covers their logs, credentials, environment variables, and mounted files.

In plain words
What is it for?
Investigating container startup failures, session-resumption problems, missing files, authentication errors, and relevant NanoClaw logs.
Why use it?
It helps locate whether a failure comes from the host application, the container, authentication, or an incorrect file mount.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is thmtz/nanoclaw-fleet's own configuration. It tells Claude Code how to work on nanoclaw-fleet itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything nanoclaw-fleet configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /home/node/.claude/.

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 1mo 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

    │ spawns container                      │ runs Claude Agent SDK
    │ with volume mounts                   │ with MCP servers

    ├── data/v2-sessions/{group}/.claude-shared/ ──> /home/node/.claude/ (per-group)
    └── (mount-allowlist) extra dirs ──> /workspace/extra/*

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

Enabling Debug Logging

Set LOG_LEVEL=debug for verbose output:

# For development
LOG_LEVEL=debug pnpm 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

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.

debug is a skill published in the GitHub repository thmtz/nanoclaw-fleet (5 stars, last pushed 5mo ago), licensed MIT. It adds 40 tokens to every session and 2,931 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it D with 2 findings (asks for root, recursive force delete). It is 92% identical to debug, differing in 85 lines, and is treated as a copy.
