log-troubleshooting

log-troubleshooting is a skill for Claude Code, Codex from comisai/comis. It costs 89 tokens per session (1,972 once invoked), scanned A, original, Apache-2.0.

A guide and command-line tool for examining daemon logs, which are records of what a background service did. It covers NDJSON logs, where each line is a data record, and Pino's numeric log levels.

In plain words
What is it for?
Use it to troubleshoot daemon failures, slow operations, warnings, and other issues recorded in ~/.comis/logs/.
Why use it?
It turns large, hard-to-scan log files into structured summaries so errors, warnings, timing, and affected modules are easier to investigate.

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 A, and why

log-troubleshooting scanned grade A with 0 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/log-digest.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 181 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Log Troubleshooting

You have read-only access to the daemon logs directory at ~/.comis/logs/.

This skill bundles scripts/log-digest.py -- a Python CLI that parses NDJSON logs and produces structured, context-friendly summaries. Use it as your primary analysis tool. It uses only Python 3 standard library (no pip install needed).

All script paths below are relative to this skill's directory. Resolve them against the directory containing the manifest file shown in <location> (e.g., if <location> is ~/.comis/skills/log-troubleshooting/SKILL.md, then scripts/log-digest.py means ~/.comis/skills/log-troubleshooting/scripts/log-digest.py). Invoke the resolved script by its absolute path while keeping the tool working directory inside the execution workspace. Never set cwd to the skill directory; it is outside workspace bounds. In command examples below, replace each relative scripts/... path with its resolved absolute path.

Quick Start

For most troubleshooting requests, start here:

python3 scripts/log-digest.py ~/.comis/logs/daemon.log

This produces a structured summary: entry count, time range, level distribution, top modules, every error and warning as a compact one-liner, slowest operations ranked by duration, and unique error messages with counts. Read the output and report findings to the user -- this single command answers most "what's wrong?" questions.

Log Location and Rotation

File Description
~/.comis/logs/daemon.log Active log (current session)
~/.comis/logs/daemon.1.log Most recent rotated log
~/.comis/logs/daemon.2.log .. daemon.5.log Older rotated logs

Rotation triggers at 10MB per file, 5 rotated files kept. Start with daemon.log (current) unless investigating a past incident.

Log Format

Each line is a single JSON object (NDJSON / Pino structured logging).

Pino level codes:

Code Name Meaning
10 TRACE Finest granularity, rarely enabled
20 DEBUG Internal steps, tool calls, intermediate state
30 INFO Boundary events: started, stopped, request complete
40 WARN Degraded but functional
50 ERROR Broken functionality
60 FATAL Unrecoverable, daemon cannot continue

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

log-troubleshooting is a skill published in the GitHub repository comisai/comis (5 stars, last pushed 4d ago), licensed Apache-2.0. It adds 89 tokens to every session and 1,972 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
