00z.ai is an open-source coding harness with premium skills updated inside release builds. AI skills are integrated into the harness and generated on the fly for your development tasks. Skills provide reusable instructions, examples, and checks for everyday development and maintenance. The details below explain how that guidance fits the workflow.
One-shot, in-context learning
Provide a task-specific procedure and worked example through skills.md. The model uses that guidance in context; this does not train or change its weights.
Integrated into the harness
Generate AI skills on the fly from the spec, codebase, and development task, including API integration instructions. Keep guidance portable across compatible local or hosted models rather than tied to a single provider.
Continuous skill improvement
Evaluate results against spec-defined acceptance checks, revise the skill, and rerun representative tasks. Keep improvements backed by evidence; one example does not guarantee reliable results on every model.
Account access
The checkout below covers the account features listed here. It is not a license fee for the open-source harness. Model licenses, local compute, and third-party API usage are not included.

00z.ai is an open-source coding harness with premium skills updated inside release builds. AI skills are integrated into the harness and generated on the fly for your development tasks. Each skill brings reusable instructions, examples, and checks into the development workflow.
What does one-shot learning with skills.md mean?
A skill supplies reusable instructions, a worked example, and checks that a model can apply in context to a spec-derived task. This is not model fine-tuning or a guarantee that one example will solve every task. Review generated work and test it against the spec.
How do skills improve over time?
The harness integrates premium skills updated inside release builds and generates task-specific AI skills on the fly. Evaluate a skill on representative tasks with spec-defined acceptance checks, inspect failures, revise the instructions or examples, and rerun the checks. Compare correctness and regressions before adopting a revision. Improvement should be measured, not assumed from more generations.
Who is 00z.ai for?
It is for developers, product teams, and people turning real workflows into applications. The focus is on making requirements actionable and preserving context through feature development, bug fixes, and ongoing maintenance.
Can skills work with open-weights models and APIs?
The harness approach keeps skills as readable guidance for compatible open-weights and API-backed models, including skills for using external APIs. Model capabilities, tool support, credentials, and infrastructure still matter. A portable skill does not make every model or API interchangeable.
