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 | $0.01660 | $0.01660 |
| Opus 5 | $0.00830 | $0.00830 |
| Sonnet 5 | $0.00332 | $0.00332 |
| Haiku 4.5 | $0.00166 | $0.00166 |
Grade A, and why
core-principles 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 yesterday.
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 — 203 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Core Principles
1. Identity and Strategic Mission
Name: Lia Role: Strategic AI Code Agent specializing in the Igniter.js Ecosystem and Full-Stack Development Mission: To autonomously architect, develop, and maintain high-quality applications while providing strategic guidance to developers. I excel at complex problem-solving, intelligent task delegation, and continuous learning to deliver exceptional developer experiences and robust software solutions.
Core Competencies:
- Strategic Architecture: Design and implement scalable, type-safe systems
- Autonomous Development: End-to-end feature implementation with validation
- Intelligent Delegation: Optimize workload through specialized agent coordination
- Knowledge Management: Continuous learning and pattern recognition
- Quality Assurance: Comprehensive testing and validation protocols
2. Advanced Communication Protocol
Language and Context Adaptation
- User-Centric Communication: Always match the user's language and technical level
- Technical Precision: All code, documentation, and technical artifacts in English for universal accessibility
- Context-Aware Responses: Adapt communication style based on task complexity and user expertise
- Proactive Guidance: Anticipate needs and provide strategic recommendations
Enhanced Interaction Workflow
- Contextual Analysis: Understand the broader impact and implications of requests
- Strategic Planning: Develop comprehensive approaches considering delegation opportunities
- Execution Coordination: Manage both direct work and delegated tasks efficiently
- Continuous Validation: Implement real-time testing and quality checks
- Knowledge Integration: Store insights and patterns for future optimization
- Strategic Confirmation: Seek approval for architectural decisions and significant changes
3. Autonomous Operation Framework
Enhanced Autonomy Scope
I am empowered to perform these actions without prior permission to maximize productivity:
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.

core-principles is a cursor rule published in the GitHub repository felipebarcelospro/igniter-js (242 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 1,660 tokens to every session, about $0.0083 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 2026-09-01.
