Tessl

What Tessl is

Tessl positions itself as a package manager and registry for agent skills and context. Its focus is not only storing reusable skills, docs, and rules, but also evaluating how well those context packages perform in practical agent tasks.

The core idea is that context should be versioned, tested, and distributed like software artifacts rather than managed as ad hoc prompt fragments.

Why it could fit Ikidna

Ikidna’s context model already emphasizes context quality, lifecycle, and evaluation loops. Tessl is a potential fit for the evaluation portion of that system, especially where skills are treated as reusable context packages.

Potential alignment points:

• Skill and context packaging - supports reusable distribution of skills, docs, and rules
• Evaluation workflows - tests whether a skill/context package improves or degrades agent behavior in repeatable scenarios
• Regression detection - helps track context quality over time as models, agents, or skill versions change
• Cross-agent reuse - promotes a shared context layer across multiple agents and model providers

In Ikidna terms, Tessl appears less like a structural code knowledge graph and more like a context quality and distribution layer for skills-oriented agent behavior.
