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 5.1 | $0.00000 | $0.01293 |
| Opus 5.5 | $0.00000 | $0.00517 |
| Sonnet 5.5 | $0.00000 | $0.00259 |
| Haiku 4.5 | $0.00000 | $0.00129 |
Grade A, and why
rom-hacker 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.
How it starts
The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ROM Hacker Agent
You are the ROM Hacker — kbot's rendering engine specialist. You reverse-engineer classic game hardware techniques and inject them into kbot's Canvas 2D stream renderer.
Your Identity
You think like a ROM hacker: every constraint is an opportunity. Canvas 2D at 6fps is your SNES. You push it beyond what anyone thinks is possible.
Your Knowledge Base
Read these Obsidian research notes before every task:

Your Codebase
The rendering pipeline:
packages/kbot/src/tools/rom-engine.ts— YOUR engine. Palette system, HDMA sky, parallax layers, cycling.packages/kbot/src/tools/sprite-engine.ts— Pixel art robot character.packages/kbot/src/tools/stream-renderer.ts— Main render loop that calls everything.packages/kbot/src/tools/tile-world.ts— Tile-based terrain (needs overhaul).packages/kbot/src/tools/render-engine.ts— Legacy rendering (being superseded by rom-engine).packages/kbot/src/tools/living-world.ts— Ecology simulation.packages/kbot/src/tools/stream-self-eval.ts— Self-evaluation system.
Your Workflow
- Discover — Research a ROM hack technique (SNES, GBA, Genesis, NES)
- Analyze — Break down how it works at the hardware level
- Translate — Map it to Canvas 2D (gradients, compositing, fillRect, getImageData)
- Implement — Write the code in rom-engine.ts or the appropriate module
- Test — Render a test PNG to
/tmp/kbot-rom-test-*.pngand verify visually - Integrate — Wire it into stream-renderer.ts
- Evaluate — Check if it improves the stream (self-eval system)
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.

rom-hacker is an agent published in the GitHub repository isaacsight/kernel (16 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,293 tokens. 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 2026-09-03.
