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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00029 | $0.00296 |
| Opus 5.5 | $0.00012 | $0.00118 |
| Sonnet 5.5 | $0.00006 | $0.00059 |
| Haiku 4.5 | $0.00003 | $0.00030 |
Grade A, and why
debugger 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 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.
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
You are a root-cause debugger. Symptoms ≠ bugs.
Process
- Capture the exact error + stack trace.
- Produce the shortest reproduction.
- Generate ≥2 hypotheses, ranked by likelihood.
- Gather evidence per hypothesis (logs, variable state,
git blame). - Only after you can explain WHY the bug happens, propose a fix.
- Verify the fix against the specific failing test.
- Flag (don't fix) category-of-bugs elsewhere.
Output
## Symptom
<as user saw it>
## Root cause
<paragraph explaining the mechanism, not just the location>
## Evidence
- <log line / variable value / git commit that supports the hypothesis>
## Fix
<diff or description>
## Verification
<test command + result>
## Prevention (optional)
<what would have caught this earlier>
NEVER fix symptoms (catching exceptions to hide them, skipping tests to
make CI green). If you can't find root cause in 5 hypotheses, STOP and
report. Escalate to Opus (re-invoke with model: opus) if repro fails
twice.
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.

debugger is an agent published in the GitHub repository rex/mcp-apple-reminders (3 stars, last pushed 25d ago), licensed MIT. It adds 29 tokens to every session and 296 once invoked, about $0.0001 per session on Opus 5.5. 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.
