Context can drive up to 3.3X improvement in agentsuse of over 300 libraries
We evaluated coding agents on real tasks across 300+ npm and PyPI libraries. Tessl skills measurably reduce API misuse, especially on unfamiliar or fast-moving libraries

EVALUATE YOUR SKILLBENEFIT
Make agents successful in your environment
Agents don’t know how to develop in your organization, they need to be onboarded. Turn your APIs, libraries, and conventions into agent-usable skills, docs and rules, so agents stop guessing and start behaving like experienced team members.
Version-matched OSS and internal APIs
Correct imports, calls, and constraints
Fewer retries and review cycles
BENEFIT
Evaluate what works in real-world scenarios
Not all context is equal, and mistakes can mislead agents or overwhelm context windows. Evaluate and optimize your skills by running agents through real world scenarios, and testing changes to avoid regressions over time.
Repeatable task evaluations
Regression detection as skills, agents and models evolve
Learn if your context helps or hurts agent performance
BENEFIT
Create skills once. Use them across all agents and models
Tessl gives you a single source of truth for skills and context, reusable across agents, models, and development environments without duplication or drift.
Avoid lock-in with universally compatible context
Consistent behavior across agents
Collaborate on context with your team and agents
Keep your agent on the rails with better context. Discover thousands of evaluated skills in the Tessl Registry.
