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 | $0.00053 | $0.00700 |
| Opus 5 | $0.00026 | $0.00350 |
| Sonnet 5 | $0.00011 | $0.00140 |
| Haiku 4.5 | $0.00005 | $0.00070 |
Grade A, and why
debug 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 2d 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.
This is a copy
100% identical to debug — 0 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.
How it starts
The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/debug
If you see unfamiliar placeholders or need to check which tools are connected, see CONNECTORS.md.
Run a structured debugging session to find and fix issues systematically.

How It Works
┌─────────────────────────────────────────────────────────────────┐
│ DEBUG │
├─────────────────────────────────────────────────────────────────┤
│ Step 1: REPRODUCE │
│ ✓ Understand the expected vs. actual behavior │
│ ✓ Identify exact reproduction steps │
│ ✓ Determine scope (when did it start? who is affected?) │
│ │
│ Step 2: ISOLATE │
│ ✓ Narrow down the component, service, or code path │
│ ✓ Check recent changes (deploys, config changes, dependencies) │
│ ✓ Review logs and error messages │
│ │
│ Step 3: DIAGNOSE │
│ ✓ Form hypotheses and test them │
│ ✓ Trace the code path │
│ ✓ Identify root cause (not just symptoms) │
│ │
│ Step 4: FIX │
│ ✓ Propose a fix with explanation │
│ ✓ Consider side effects and edge cases │
│ ✓ Suggest tests to prevent regression │

What I Need From You
Tell me about the problem. Any of these help:
- Error message or stack trace
- Steps to reproduce
- What changed recently
- Logs or screenshots
- Expected vs. actual behavior
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.

debug is a skill published in the GitHub repository openyak/openyak (703 stars, last pushed 5d ago), licensed Apache-2.0. It adds 53 tokens to every session and 700 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to debug, differing in 0 lines, and is treated as a copy.

One-click deploy a user's pre-built app/artifact into their OWN AWS account and get a global public HTTPS link (Vercel-like), with a default TTL and promote-to-persistent. Use when the user says "deploy this", "ship this demo", "give me a public link", "share this externally", or "deploy to AWS".

Look at your OWN front-end change before claiming it works -- navigate the loopback URL of a dev server or pod you started, screenshot the surface you changed, read the image to judge it, and embed it in chat.
