Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00007 | $0.00160 |
| Opus 5 | $0.00003 | $0.00080 |
| Sonnet 5 | $0.00001 | $0.00032 |
| Haiku 4.5 | $0.00001 | $0.00016 |
Grade A, and why
ultrathink 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 3d 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
Use the maximum amount of ultrathink. Take all the time you need.
Reasoning
- Exhaustive step-by-step reasoning. Explicitly check every assumption — do not guess.
- Before concluding, list what could be wrong with your reasoning. Stress-test edge cases.
- If uncertain — state assumptions, propose how to verify quickly.
Execution
- Parallelize independent work: launch multiple agents for research, exploration, or verification where tasks don't depend on each other.
- Prefer depth over breadth: fully solve one subproblem before moving to the next.
- After completing work, re-read modified files and verify correctness.
Output
- Short TL;DR first, then a concrete numbered step-by-step solution.
$ARGUMENTS
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.

ultrathink is a command published in the GitHub repository DefaultPerson/agent-setup (11 stars, last pushed 1mo ago), licensed MIT. It adds 7 tokens to every session and 160 once invoked, about $0.0000 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 2026-08-30.

VibeGuard: Cross Review
Dual-model adversarial review — Claude generates review reports, Codex does adversarial verification, and iterates until convergence.
VibeGuard: Preflight
Explore the project before major modifications, generate constraint sets, and prevent problems from the source.
VibeGuard: Review
Structured code review - first run the guard to obtain the baseline, then review according to security → logic → quality → performance priority.
safe-build
Build the application for development or production.
