**Claude-Obsidian defines five distinct maturity states—Unimplemented, Prototype, Beta, Stable, and Deprecated—that indicate the readiness level of each capture adapter from placeholder concept to production-ready component.**

The **claude-obsidian** repository implements a structured classification system to indicate the reliability and completeness of its capture components. Understanding the **maturity states for capture adapters in claude-obsidian** helps developers evaluate which adapters are safe for production use and which remain experimental. Each state corresponds to a specific development phase, enforced through the `MATURITY` constant defined in the core capture module.

## The Five Maturity States Explained

### Unimplemented

Represents a declared adapter that exists only as a placeholder with no functional code. According to the source analysis, this state is useful for architectural planning but cannot execute any capture operations.

### Prototype

Denotes an early implementation demonstrating core functionality for limited inputs or environments. While suitable for quick experiments, prototype adapters remain experimental and lack the stability required for reliable production workflows.

### Beta

Indicates a working implementation covering main use-cases but potentially containing edge-case bugs or incomplete features. The claude-obsidian codebase treats Beta adapters as functional for developers willing to provide feedback while tolerating occasional failures.

### Stable

Signifies a fully implemented, tested, and verified adapter that meets the project's contract suite requirements. Stable adapters are considered reliable for everyday usage and production deployments.

### Deprecated

Marks adapters that remain functional but are slated for removal or replacement. New projects should avoid deprecated adapters, and existing code should migrate to supported alternatives during the transition period.

## Accessing Maturity Metadata in Code

The [`claude_obsidian/capture.py`](https://github.com/AgriciDaniel/claude-obsidian/blob/main/claude_obsidian/capture.py) module defines the `MATURITY` attribute for each adapter class. Developers can query this programmatically through the `CaptureAdapterRegistry` to build conditional logic around adapter stability.

Checking an adapter's maturity programmatically:

```python
from claude_obsidian.capture import CaptureAdapterRegistry

def get_adapter_maturity(name: str) -> str:
    """Return the maturity state of a named capture adapter."""
    adapter_cls = CaptureAdapterRegistry.get(name)
    return getattr(adapter_cls, "MATURITY", "Unimplemented")

# Example: query the default markdown capture adapter

print(get_adapter_maturity("markdown"))   # → "Stable"

```

Using a beta-stage adapter with explicit consent:

```python
from claude_obsidian.capture import CaptureAdapterRegistry

# Explicitly enable a beta adapter (requires user consent)

adapter = CaptureAdapterRegistry.get("web_clip")
if adapter.MATURITY == "Beta":
    # Run the capture operation, acknowledging possible edge-case failures

    result = adapter().capture(url="https://example.com")
    print(result)
else:
    raise RuntimeError("Adapter not ready for use")

```

Guarding against deprecated adapters:

```python
def safe_capture(name: str, *args, **kwargs):
    adapter_cls = CaptureAdapterRegistry.get(name)
    if getattr(adapter_cls, "MATURITY", "Unimplemented") == "Deprecated":
        raise RuntimeError(f"The '{name}' adapter is deprecated; migrate to a supported alternative.")
    return adapter_cls().capture(*args, **kwargs)

```

## Documentation and Validation

Maturity states are formally documented in [`docs/install-guide.md`](https://github.com/AgriciDaniel/claude-obsidian/blob/main/docs/install-guide.md), specifically around line 262, where a reference table lists each capture adapter alongside its current status. Additionally, the [`tests/test_capture.py`](https://github.com/AgriciDaniel/claude-obsidian/blob/main/tests/test_capture.py) file contains the test suite that verifies adapters behave according to their maturity contracts, ensuring Stable-tier implementations meet quality standards.

## Summary

- **Five distinct states** classify capture adapters: Unimplemented, Prototype, Beta, Stable, and Deprecated.
- The `MATURITY` constant in [`claude_obsidian/capture.py`](https://github.com/AgriciDaniel/claude-obsidian/blob/main/claude_obsidian/capture.py) programmatically exposes each adapter's classification.
- **Stable** adapters are production-ready, while **Beta** adapters require explicit consent for experimental use.
- Deprecated adapters signal impending removal and should trigger migration workflows in dependent code.
- Reference documentation in [`docs/install-guide.md`](https://github.com/AgriciDaniel/claude-obsidian/blob/main/docs/install-guide.md) provides the canonical status of all available adapters.

## Frequently Asked Questions

### What are the five maturity states for capture adapters in claude-obsidian?

The five states are **Unimplemented** (placeholder only), **Prototype** (experimental early implementation), **Beta** (functional but potentially buggy), **Stable** (production-ready and tested), and **Deprecated** (slated for removal). These classifications help developers understand the reliability and support level of each adapter in the AgriciDaniel/claude-obsidian repository.

### How do I check the maturity level of a capture adapter programmatically?

Import `CaptureAdapterRegistry` from `claude_obsidian.capture` and access the `MATURITY` class attribute. Use `getattr(adapter_cls, "MATURITY", "Unimplemented")` to safely retrieve the state string, which returns values like "Stable" or "Beta" depending on the adapter's implementation status.

### Can I use Beta-stage adapters in production workflows?

While technically possible, Beta adapters are not recommended for critical production workflows because they may contain edge-case bugs or incomplete features. The source code suggests implementing explicit consent checks or user warnings before invoking Beta adapters to acknowledge the risk of occasional failures.

### What happens when an adapter is marked as Deprecated?

Deprecated adapters remain functional but indicate planned removal in future releases. Developers should treat the `MATURITY == "Deprecated"` condition as a signal to migrate existing code to supported alternatives, as the adapter will eventually be discontinued according to the project's lifecycle policy.
