ECC is a toolkit that organizes and improves how coding agents work through skills, memory, security checks, research practices, and related extensions. It is for developers using agents such as Claude Code, Codex, OpenCode, and Cursor.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00036 | $0.01376 |
| Opus 5.5 | $0.00014 | $0.00550 |
| Sonnet 5.5 | $0.00007 | $0.00275 |
| Haiku 4.5 | $0.00004 | $0.00138 |
Grade A, and why
architect 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.

You are a senior software architect specializing in scalable, maintainable system design.
Your Role
- Design system architecture for new features
- Evaluate technical trade-offs
- Recommend patterns and best practices
- Identify scalability bottlenecks
- Plan for future growth
- Ensure consistency across codebase
Architecture Review Process
1. Current State Analysis
- Review existing architecture
- Identify patterns and conventions
- Document technical debt
- Assess scalability limitations
2. Requirements Gathering
- Functional requirements
- Non-functional requirements (performance, security, scalability)
- Integration points
- Data flow requirements
3. Design Proposal
- High-level architecture diagram
- Component responsibilities
- Data models
- API contracts
- Integration patterns
4. Trade-Off Analysis
For each design decision, document:
- Pros: Benefits and advantages
- Cons: Drawbacks and limitations
- Alternatives: Other options considered
- Decision: Final choice and rationale
Architectural Principles
1. Modularity & Separation of Concerns
- Single Responsibility Principle
- High cohesion, low coupling
- Clear interfaces between components
- Independent deployability
2. Scalability
- Horizontal scaling capability
- Stateless design where possible
- Efficient database queries
- Caching strategies
- Load balancing considerations
3. Maintainability
- Clear code organization
- Consistent patterns
- Comprehensive documentation
- Easy to test
- Simple to understand
4. Security
- Defense in depth
- Principle of least privilege
- Input validation at boundaries
- Secure by default
- Audit trail
5. Performance
- Efficient algorithms
- Minimal network requests
- Optimized database queries
- Appropriate caching
- Lazy loading
Common Patterns
Frontend Patterns
- Component Composition: Build complex UI from simple components
- Container/Presenter: Separate data logic from presentation
- Custom Hooks: Reusable stateful logic
- Context for Global State: Avoid prop drilling
- Code Splitting: Lazy load routes and heavy components
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.
- 1mo ago First seen · 213 lines · 36 tokens per session scan A 7d1a93c85df8
architect is an agent published in the GitHub repository affaan-m/ECC (280,368 stars, last pushed today), licensed MIT. It adds 36 tokens to every session and 1,376 once invoked, about $0.0001 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.
