CSL v1.0.0
Initial Public Specification
This release marks the first public specification of the Cognitive Specification Language (CSL).
CSL is a domain-specific language (DSL) for specifying AI behavioral architecture independently from implementation.
Rather than treating AI behavior as a monolithic prompt, CSL decomposes behavior into independent architectural layers that can be composed, reasoned about, and implemented across different host languages.
Included
- Foundational Module Layout (FML)
- Five-stage behavioral architecture
- Character specification
- Environment specification
- Decision Synthesis architecture
- Resolver-based composition model
- Confidence scalar
- Python reference host implementation
- Complete documentation
- MPL 2.0 licensing
Scope
This release establishes the architectural specification.
It does not represent a finished ecosystem.
Future work includes:
- Dedicated parser
- Intermediate Representation (IR)
- Additional host language implementations
- Validation tooling
- Static analysis
- Behavioral libraries
Philosophy
CSL prioritizes architectural clarity over implementation complexity.
Behavior should emerge through explicit composition rather than hidden side effects.
Identity remains immutable.
Environment remains descriptive.
Decision Synthesis computes behavior.
Status
Specification Stable
The architecture described in this release is intended to serve as the foundational reference for future CSL development.
Thank you to everyone who takes the time to read, critique, and stress-test the architecture.
