# ADR-0008: Use Anthropic Canonical Messages With Provider Adapters
|

|
## Context
|
|
|
|
AirCoding needs provider flexibility while preserving a stable internal representation for prompts, tools, messages, context compaction, and session persistence.
|
|
|
|
## Decision
|
|
|
|
Use Anthropic canonical content blocks internally. ContextAssembler emits Anthropic canonical messages. Provider adapters convert at the LLM boundary to Anthropic, OpenAI, OpenRouter, ollama, or compatible endpoints.
|
|
|
|
Provider capability matrix controls whether a model can satisfy the task and whether conversion is lossless, lossy, or unsupported.
|
|
|
|
## Consequences
|
|
|
|
- Same-provider model switching has low conversion cost.
|
|
- Cross-provider differences are localized to adapters.
|
|
- Unsupported required features block before model call.
|
|
- Tool/result/message persistence remains stable across providers.
