cjm-capability-primitives 0.0.4

The dep-light primitives library for the cjm capability ecosystem — defines the shared cross-task result DTOs (data nouns) that tool capabilities emit and task adapters, workflow cores, and the composition layer all consume, so a pure-compute tool capability depends only on its task's data noun, never on the adapter machinery.

Module Overview

Detailed documentation for each module in the project:

Transcription Result (transcription.ipynb)

Standardized result DTO for the transcription task — the data noun tool capabilities emit and task adapters / workflow cores consume, wire-registered so results cross the worker boundary typed.

Import

from cjm_capability_primitives.transcription import (
    TranscriptionResult
)

Classes

@dataclass
class TranscriptionResult:
    "Standardized output for all transcription plugins."
    
    text: str  # The transcribed text
    confidence: Optional[float]  # Overall confidence (0.0 to 1.0)
    segments: Optional[List[Dict[str, Any]]]  # Timestamped segments
    metadata: Dict[str, Any] = field(...)  # Additional metadata

VAD Result (vad.ipynb)

Standardized result DTO for the voice-activity-detection task — the data noun VAD tool capabilities emit and task adapters / workflow cores consume, wire-registered so results cross the worker boundary typed.

Import

from cjm_capability_primitives.vad import (
    TimeRange,
    VADResult
)

Classes

@dataclass
class TimeRange:
    "A temporal segment within an audio source (the VAD speech/silence span)."
    
    start: float  # Start time in seconds
    end: float  # End time in seconds
    label: str = 'speech'  # Segment type (e.g. 'speech')
    confidence: Optional[float]  # Detection confidence (0.0 to 1.0)
    payload: Dict[str, Any] = field(...)  # Extra data (reserved)
    
    def to_dict(self) -> Dict[str, Any]:  # Serialized representation
        "Convert to dictionary for JSON serialization."

@dataclass
class VADResult:
    "Standardized output for voice-activity-detection capabilities."
    
    ranges: List[TimeRange]  # Detected speech segments, sorted by start
    metadata: Dict[str, Any] = field(...)  # Global VAD stats (duration, sample_rate, total_speech, ...)
    
    def from_dict(
        "Reconstruct from a wire payload, re-typing nested TimeRanges.

`ranges` holds typed `TimeRange` objects, so the substrate's typed wire
envelope (stage 2) reconstructs them host-side here rather than leaving
bare dicts (which would break attribute access like `r.start`)."
