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

analyze-crash 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 9d 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.

Origin

This is a copy

92% identical to analyze-crash — 9 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Analyze Crash Log

Launches the crash-analyzer agent to parse crash reports and identify the root cause.

What It Does

The agent will:

  1. Parse the crash report (JSON .ips or text .crash format)
  2. Extract key fields (exception type, codes, crashed thread, frames)
  3. Check symbolication status
  4. Categorize by crash pattern (null pointer, Swift runtime, watchdog, jetsam, etc.)
  5. Generate actionable analysis with specific next steps

Crash Sources

Provide crashes via:

  • Pasted text -- Copy/paste the crash report directly
  • File path -- ~/Library/Logs/DiagnosticReports/MyApp.ips
  • Xcode export -- Copied from Organizer

Crash Log Locations

# macOS/iOS Simulator crash logs
~/Library/Logs/DiagnosticReports/*.ips

# Device crash logs (after sync)
~/Library/Logs/CrashReporter/MobileDevice/<DeviceName>/

Prefer Natural Language?

  • "Analyze this crash log"
  • "Here's a crash from TestFlight, what's wrong?"
  • "Parse this .ips file"
  • "Why did my app crash?"

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.
