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.

What it costs to keep this loaded
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 | $0.00035 | $0.00649 |
| Opus 5 | $0.00017 | $0.00324 |
| Sonnet 5 | $0.00007 | $0.00130 |
| Haiku 4.5 | $0.00003 | $0.00065 |
Grade A, and why
monorepo-management 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 9d 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.

Monorepo Management
Table of Contents
Overview
Establish scalable monorepo structures that support multiple interdependent packages while maintaining build efficiency, dependency management, and deployment coordination.
When to Use
- Multi-package projects
- Shared libraries across services
- Microservices architecture
- Plugin-based systems
- Multi-app platforms (web + mobile)
- Workspace dependency management
- Scaled team development
Quick Start
Minimal working example:
{
"name": "monorepo-root",
"version": "1.0.0",
"private": true,
"workspaces": ["packages/*", "apps/*"],
"devDependencies": {
"lerna": "^7.0.0",
"turbo": "^1.10.0"
},
"scripts": {
"lint": "npm run lint -r",
"test": "npm run test -r",
"build": "npm run build -r",
"clean": "npm run clean -r"
}
}

Best Practices
✅ DO
- Use workspace protocols for dependencies
- Implement shared tsconfig for consistency
- Cache build outputs in CI/CD
- Filter packages in CI to avoid unnecessary builds
- Hoist common dependencies
- Document workspace structure
- Use consistent versioning strategy
- Implement pre-commit hooks across workspace
- Test cross-package dependencies
- Version packages independently when appropriate

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.

monorepo-management is a skill published in the GitHub repository aj-geddes/useful-ai-prompts (338 stars, last pushed 6mo ago), licensed MIT. It adds 35 tokens to every session and 649 once invoked, about $0.0002 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 2026-09-03.
