pawagent 0.2.2

A Python library for building AI systems that understand pets.

PawAgent

PawAgent is a Python framework for pet understanding from images and short videos.

It provides a reusable analysis stack for:

• Emotion analysis
• Behavior analysis
• Motivation prediction
• Expression rendering
• Pet identity enrollment and verification

PawAgent is a library, not a web service. It is intended to sit underneath a separate runtime or application layer.

Status

• Core media analysis: implemented
• Image and short-video task views: implemented
• Identity verification: implemented
• Real local identity path (maskrcnn + openclip): implemented
• Audio: internal extension path, not a primary user-facing workflow
• Live streaming: out of scope for the current product surface

Why This Project

Most pet-AI demos collapse everything into one opaque caption. PawAgent instead separates:

• direct observations
• second-layer inference
• human-readable rendering

That makes the results easier to cache, explain, reuse, and evaluate.

Core Model

One image or short video produces one unified analysis result:

{
  "emotion": {},
  "behavior": {},
  "motivation": {},
  "expression": {},
  "evidence": []
}

Task-specific agents then read from that shared result instead of re-calling the model.

Result layering:

• First layer: emotion, behavior
• Second layer: motivation
• Expression layer: expression

Feature Matrix

Capability	Image	Short Video	Notes
Emotion	Yes	Yes	First-layer structured result
Behavior	Yes	Yes	Video usually gives stronger behavior cues
Motivation	Yes	Yes	Second-layer inference from emotion + behavior
Expression	Yes	Yes	Stable rendering over structured analysis
Identity	Yes	No	Separate verification pipeline
Audio	Internal	Internal	Not a primary user-facing workflow

Quick Start

Install from PyPI:

pip install pawagent

Install from source for development:

pip install -e .

Run the mock provider:

pawagent analyze-emotion dog.jpg --pet-id pet-1 --pet-name Milo
pawagent analyze-behavior clip.mp4 --pet-id pet-1 --pet-name Milo --modality video
pawagent express-pet dog.jpg --pet-id pet-1 --pet-name Milo --locale zh-CN

Install identity extras:

pip install -e ".[identity]"

Run real local identity verification:

pawagent enroll-identity tests/coconut.jpg --pet-id pet-1 --identity-cropper maskrcnn --identity-embedder openclip
pawagent verify-identity tests/coconut.jpg --pet-id pet-1 --identity-cropper maskrcnn --identity-embedder openclip

CLI Overview

Task-view commands:

pawagent analyze-emotion <source> --modality image|video
pawagent analyze-behavior <source> --modality image|video
pawagent analyze-motivation <source> --modality image|video
pawagent express-pet <source> --modality image|video

Identity commands:

pawagent enroll-identity <source> --pet-id <pet-id>
pawagent verify-identity <source> --pet-id <pet-id>

Example Commands

Image emotion:

pawagent analyze-emotion dog.jpg --pet-id pet-1 --pet-name Milo

Short-video behavior:

pawagent analyze-behavior clip.mp4 --pet-id pet-1 --pet-name Milo --modality video

Localized expression:

pawagent express-pet dog.jpg --pet-id pet-1 --pet-name Milo --locale zh-CN

HEIC input:

pawagent analyze-emotion tests/coconut.heic --pet-id pet-1 --pet-name Coconut

Image Formats

Supported image inputs include:

• JPG
• PNG
• WEBP
• HEIC
• HEIF

HEIC/HEIF inputs are decoded locally before provider upload or identity fingerprinting.

On macOS, PawAgent can fall back to the system sips converter when pillow-heif is unavailable.

Providers

Built-in provider options:

• mock
• openai
• gemini
• gemini-cli
• codex
• claude
• claude-cli

OpenAI

export OPENAI_API_KEY=your_api_key
pawagent --provider openai --openai-model gpt-4.1-mini analyze-emotion dog.jpg --pet-id pet-1 --pet-name Milo

OpenAI Platform API integration uses API keys for server-side model calls.

Gemini

export GEMINI_API_KEY=your_api_key
pawagent --provider gemini --gemini-model gemini-2.5-flash analyze-emotion dog.jpg --pet-id pet-1 --pet-name Milo

Claude

export ANTHROPIC_API_KEY=your_api_key
pawagent --provider claude --claude-model claude-sonnet-4-6 analyze-emotion dog.jpg --pet-id pet-1 --pet-name Milo

Anthropic Claude API integration uses API keys for server-side model calls. Claude's strong vision capabilities make it well-suited for pet image analysis.

Claude CLI

claude
pawagent --provider claude-cli --claude-model claude-sonnet-4-6 analyze-emotion dog.jpg --pet-id pet-1 --pet-name Milo

This provider shells out to the local claude CLI (Claude Code) and reuses its existing login state.

Codex CLI

codex login
pawagent --provider codex --codex-model gpt-5.4 analyze-emotion dog.jpg --pet-id pet-1 --pet-name Milo

This provider shells out to the local codex CLI and reuses its existing login state.

Gemini CLI

gemini
pawagent --provider gemini-cli --gemini-model gemini-2.5-flash analyze-emotion dog.jpg --pet-id pet-1 --pet-name Milo

Identity

Identity is separate from emotion and behavior analysis. It uses its own profile store and should be treated as probabilistic verification, not biometric certainty.

Implementation paths:

• Fallback path: noop cropper + hash embedder
• Intended local path: maskrcnn cropper + openclip embedder

Identity enrollment is append-only. Repeated enroll-identity calls for the same pet-id add new reference views instead of overwriting the profile.

Real Local Identity Notes

• the first openclip run may download files into .pawagent/hf-cache and .pawagent/torch-cache
• a Hugging Face unauthenticated-request warning during first download is expected
• HF_TOKEN is optional for public models and only improves download rate limits
• verification compares against all enrolled references for the target pet-id

Architecture

Task Views
  -> Unified Analysis
  -> Capability Layer (vision / video)
  -> Provider Layer

Supporting layers:
  - Memory / cache
  - Identity
  - Shared models

Key design rules:

• one source item should map to one unified analysis result
• repeated task-view requests should reuse cached analysis
• localized expression may use a lightweight second pass and is cached separately
• identity should never reuse emotion/behavior memory as its source of truth
