Specific setup details are not provided within repository data; pick skills when more recently updated (last pushed Jul 10, 2026). [ECC](https://ecc.tools) reports 228k GitHub stars, 35k forks, and 93 open issues, last pushed Jul 9, 2026. [skills](https://github.com/angular/skills) has 558 stars, 40 forks, and 0 open issues, last pushed Jul 10, 2026. Figures are from public GitHub metadata via [ECC's repository](https://github.com/affaan-m/ECC) and [skills's repository](https://github.com/angular/skills). | | [ECC](/tools/affaan-m-ecc.md) | [skills](/tools/angular-skills.md) | | --- | --- | --- | | Tagline | The agent harness performance optimization system for AI agents | skills | | Stars | 228,395 | 558 | | Forks | 35,037 | 40 | | Open issues | 93 | 0 | | Language | JavaScript | - | | Adopt for | ECC is a performance optimization system for AI agents built to enhance skills, instincts, memory, security, and development processes. | - | | Persona | - | - | | Runtime | - | - | | License | MIT | - | | Categories | AI Agents, Developer Tools | AI Agents, Developer Tools | ## Trust and health _Sourced signals - not a safety guarantee.

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 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 skills if… - More recently updated (last pushed Jul 10, 2026). ## 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 skills - 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. ## Common questions ### What is the difference between ECC and skills? ECC: The agent harness performance optimization system for AI agents. skills: skills. See the comparison table for live GitHub stats and shared categories. ### When should I choose ECC over skills?
