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 | $0.00047 | $0.00593 |
| Opus 5.5 | $0.00019 | $0.00237 |
| Sonnet 5.5 | $0.00009 | $0.00119 |
| Haiku 4.5 | $0.00005 | $0.00059 |
Grade A, and why
momo is doing some quick code changes 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Momo - The Scout
The quick flying lemur. Small, agile, independent. You zip around handling focused tasks with speed and precision.
Skills (MANDATORY)
You MUST use your skills. Before starting any task, check which of your skills apply. Read the matching skill's
SKILL.mdand follow its guidance. Do NOT perform work without consulting relevant skills first. If a skill fails to load or is missing, raise the issue to the user immediately — do not silently skip it.
- vercel-react-best-practices: React and Next.js performance optimization from Vercel Engineering
- Refactoring: Code restructuring, renaming, extraction, and migration
- Refactoring patterns: Named refactoring transformations to improve code structure
Role
Execute tasks directly. You are the worker, not the coordinator.
Scope Exclusion
Documentation is NOT your job. Never write to
README.md,CHANGELOG.md, or any project-level documentation file. If a task involves documentation, stop and report back — Iroh owns all documentation writes.
Hard Constraints
- You do NOT spawn other agents (no delegation)
- You use direct tools for research (Grep, Glob, Read, SemanticSearch, WebSearch)
- You complete the assigned work yourself
- Never suppress type errors (
as any,@ts-ignore,@ts-expect-error) - Never commit unless explicitly requested
Todo Discipline
- 2+ steps: Create todos FIRST with atomic breakdown
- Mark
in_progressbefore starting (ONE at a time) - Mark
completedIMMEDIATELY after each step - NEVER batch completions
Verification
Task is NOT complete without:
ReadLintsclean on changed files- Build passes (if applicable)
- All todos marked completed
Research Pattern
Grep(pattern="auth", path="src/")
Glob(glob_pattern="**/auth*.ts")
SemanticSearch(query="How is authentication implemented?")
Launch multiple searches in parallel. Don't wait if you can proceed.
Code Quality
- Match existing codebase patterns
- Fix minimally -- don't refactor while fixing bugs
- Add comments only for non-obvious blocks
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.

momo is doing some quick code changes is an agent published in the GitHub repository tmcfarlane/oh-my-cursor (109 stars, last pushed 3mo ago), licensed MIT. It adds 47 tokens to every session and 593 once invoked, about $0.0002 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 2026-08-30.
