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 2mo 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"
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.
