log-analyzer

log-analyzer is a skill for Claude Code, Codex from fisker086/AIOps. It costs 19 tokens per session (207 once invoked), scanned A, original, Apache-2.0.

A log-reading tool for turning nginx, syslog, Apache, and application JSON logs into structured information.

In plain words
What is it for?
Use it to parse log entries, filter them by level, time, or pattern, and summarize errors, top IP addresses, and other counts.
Why use it?
It removes the need to inspect large log files line by line or write one-off parsing scripts.

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-analyzer 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.

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.

What it actually says

Log Analyzer Skill

Provides log parsing and analysis capabilities:

  • Parse common log formats: nginx access/error, syslog, Apache, application JSON logs
  • Extract structured fields from log lines
  • Filter logs by level, time range, or pattern
  • Summarize log statistics (error counts, top IPs, etc.)

Use builtin_log_analyzer tool with fields:

  • operation: one of "parse", "filter", "summarize"
  • log_content: the log content to analyze
  • format: (optional) log format hint: "nginx", "syslog", "apache", "json", "auto"
  • filter_level: (optional) for "filter" operation: "debug", "info", "warn", "error", "fatal"

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.
