## Decision facts: ECC

- **Hosting:** unknown - ECC requires JavaScript environment and is open-source, licensed under MIT. Specific setup details are not provided within repository data.
- **Pricing:** freemium - Being open source with an MIT license, ECC itself is free to use, but additional features or support might incur costs outside of the core project.
- **Adopt for:** ECC is a performance optimization system for AI agents built to enhance skills, instincts, memory, security, and development processes.

## Choose when

### Choose ECC if…

- ECC is primarily JavaScript; synthadoc is Python.
- License: ECC is MIT, synthadoc is AGPL-3.0.
- ECC requires JavaScript environment and is open-source, licensed under MIT. Specific setup details are not provided within repository data.
- Pricing: Being open source with an MIT license, ECC itself is free to use, but additional features or support might incur costs outside of the core project..
- Tags unique to ECC: ai-agents, anthropic, claude, claude code.
- When you are specifically working with AI agents like Claude Code and Codex that require advanced performance tuning across multiple dimensions such as skills and memory management.

### Choose synthadoc if…

- synthadoc is primarily Python; ECC is JavaScript.
- License: synthadoc is AGPL-3.0, ECC is MIT.
- Tags unique to synthadoc: agent-skills, agentic-ai, cli-tool, domain-adaptation.
- Also covers LLM Frameworks.

## When NOT to use ECC

- For projects focusing solely on traditional software development workflows without AI components, ECC's specialized tools are not necessary.
- In scenarios where you're working with closed-source or proprietary AI systems that do not allow for the same levels of customization as open platforms like those optimized by ECC.

## When NOT to use synthadoc

- AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism.
- Developer Tools: A gateway is overkill when you're pinned to a single provider and model.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
