Create a Custom Adapter

Adapters connect RaiSE to external services. They implement Python Protocol contracts and are discovered via entry points.

Protocol Contracts

RaiSE defines two primary adapter protocols in rai_cli.adapters.protocols:

ProjectManagementAdapter — for issue trackers:

from typing import Protocol, runtime_checkable

@runtime_checkable
class ProjectManagementAdapter(Protocol):
    def create_issue(self, project_key: str, issue: IssueSpec) -> IssueRef: ...
    def get_issue(self, key: str) -> IssueDetail: ...
    def update_issue(self, key: str, fields: dict[str, Any]) -> IssueRef: ...
    def transition_issue(self, key: str, status: str) -> IssueRef: ...
    def search(self, query: str, limit: int = 50) -> list[IssueSummary]: ...
    def health(self) -> AdapterHealth: ...

DocumentationTarget — for docs platforms:

@runtime_checkable
class DocumentationTarget(Protocol):
    def can_publish(self, doc_type: str, metadata: dict[str, Any]) -> bool: ...
    def publish(self, doc_type: str, content: str, metadata: dict[str, Any]) -> PublishResult: ...
    def get_page(self, identifier: str) -> PageContent: ...
    def search(self, query: str, limit: int = 10) -> list[PageSummary]: ...
    def health(self) -> AdapterHealth: ...

Both are @runtime_checkable, so RaiSE verifies compliance with isinstance().

Async-First Architecture

Concrete adapters implement the async variants (AsyncProjectManagementAdapter, AsyncDocumentationTarget). The CLI consumes sync wrappers:

from rai_cli.adapters.sync import SyncPMAdapter

class MyTrackerAsync:
    async def create_issue(self, project_key, issue):
        # Your async implementation
        ...

# CLI consumption
adapter = SyncPMAdapter(MyTrackerAsync())

Entry Point Registration

Register your adapter in pyproject.toml:

[project.entry-points."rai.adapters.pm"]
my-tracker = "my_package.adapter:MyTrackerAdapter"

[project.entry-points."rai.docs.targets"]
my-docs = "my_package.docs:MyDocsTarget"

The entry point group names are stable contracts:

• rai.adapters.pm — project management
• rai.docs.targets — documentation
• rai.governance.schemas — governance schemas
• rai.governance.parsers — governance parsers
• rai.graph.backends — graph storage

Validation

After registration, verify your adapter:

# List all discovered adapters
rai adapter list

# Check Protocol compliance
rai adapter check

# Validate declarative YAML config
rai adapter validate .raise/adapters/my-tracker.yaml

rai adapter check loads every registered entry point and runs isinstance() against the Protocol contract. Failures show which methods are missing.
