assistant

Shared GPT + classifier + regressor inference gateway for persona monitor tasks.

The "warm pond" — /assistant can autonomously evolve its inference stack via /assistant-lab (self-improvement workbench: create-*, *-lab, model factory) while /monitor-skills provides observability across the skill ecosystem.

Prompt Iteration Rule (NON-NEGOTIABLE)

All system prompts for /assistant models MUST be iterated through /prompt-lab before being baked into training data via /create-gpt. NEVER hand-craft system prompts in Python strings.

• New model prompt → /prompt-lab eval against ground truth first
• Prompt plateau (80-90% shadow agreement) → /prompt-lab compare across variants
• Model retraining → validate prompt with /prompt-lab find-minimum before /create-gpt

Tier Cascade

Tier	Method	Cost	Latency	Created By
0	Heuristic (regex/keyword/schema)	free	microseconds	hand-coded
0.5	Classifier (DistilBERT/sklearn)	free	5-25ms	/create-classifier
0.75	Regressor (sklearn/XGB)	free	5-10ms	/create-regressor
1.5	Shared GPT (Qwen3-0.6B GGUF)	free	~200ms	/create-gpt
2	scillm (DeepSeek V3.2 via Chutes)	$0.12/1K	2-5s	persona teacher

Model Lifecycle (Warm Pond)

Tier 2 persona teacher creates labels
    ↓ harvest.py extracts shadow.jsonl
    ↓
ModelFactory.auto_improve(task)
    ↓ reads shadow agreement rate
    ├─ >= 90%: promote (shadow_mode → false)
    ├─ 80-90%: plateau → /prompt-lab redesign
    ├─ 70-80%: /create-gpt or /create-classifier retrain
    └─ < 70%: aggressive retrain + architecture change
    ↓
/gpt-lab benchmark or /classifier-lab evaluate
    ↓ passing? → promote to registry
    ↓
/monitor-skills detects drift or health issues
    ↓
/assistant-lab auto-improve (diagnose → train → eval → promote)

Usage

# Validate data through tier cascade
./run.sh validate --task qra-assessor --scope brandon_bailey --input '{"question":"...", "answer":"..."}'

# Classify text
./run.sh classify --task bridge-tagger --text "satellite vulnerability assessment"

# Register a new model
./run.sh register --task NAME --model-path PATH --type gpt|classifier --threshold 0.85

# Show registered models, hit rates, tier distribution
./run.sh status

# Run synthetic input through all tiers
./run.sh self-test

# Extract tier-2 escalations as training data
./run.sh harvest --since 24h

Python API

from assistant import validate, classify

# Validate with 4-tier cascade
result = validate(
    input_data={"question": "What is CWE-79?", "answer": "Cross-site scripting..."},
    task="qra-assessor",
    scope="brandon_bailey",
)
print(result.tier, result.confidence, result.result)

# Classify with 3-tier cascade
result = classify(
    text="satellite vulnerability assessment",
    task="bridge-tagger",
)
print(result.prediction, result.confidence, result.source)

Contract

• Input: Task-specific dict (validators) or text string (classifiers)
• Output: GatewayResult or ClassifyResult with tier, confidence, latency
• Dependencies: loguru, typer; optional: llama-cpp-python, torch, joblib
• Metrics: Appends JSONL to ~/.pi/assistant/metrics.jsonl

Model Factory

# Check what models a task needs
./run.sh factory needs --task stress-test-grader

# Train a GPT from harvested teacher labels
./run.sh factory train-gpt --task stress-test-grader

# Evaluate via /gpt-lab
./run.sh factory evaluate --task stress-test-grader --type gpt

# Promote a passing model (disables shadow mode)
./run.sh factory promote --task stress-test-grader --type gpt

# Autonomous improvement loop (decide + train + eval + promote)
./run.sh factory auto-improve --task stress-test-grader

from model_factory import ModelFactory

factory = ModelFactory()
result = factory.auto_improve("stress-test-grader")
# → reads shadow agreement, trains/evals/promotes as needed

Key Behaviors

1. Lazy model loading: Weights loaded on first call, cached in-process
2. Memory injection: Recalls from persona scope, prepends to GPT system prompt
3. Passthrough mode: Falls directly to scillm if no local model exists
4. Shadow mode: Tasks with "shadow_mode": true run local model AND scillm in parallel, log disagreements to shadow.jsonl, return the teacher (scillm) result. Enables safe ramp-up of new student models.
5. Harvest: Nightly extraction of tier-2 escalations as teacher labels
6. Model Factory: Via /assistant-lab, autonomously trains, evaluates, and promotes models when shadow mode shows a task needs improvement
7. Warm Pond: /monitor-skills watches the ecosystem (observability), /assistant-lab fixes problems (self-improvement). Together they form the warm pond where /assistant evolves.

Common Mistakes

WRONG: Hand-crafting system prompts in Python strings

SYSTEM_PROMPT = "You are a QRA validator. Check if the answer is correct..."

RIGHT: Iterate prompts through /prompt-lab before baking into training data

.pi/skills/prompt-lab/run.sh eval --prompt qra_validator_v1 --model deepseek
# Only after prompt-lab validation → create training data

WRONG: Training with insufficient data (< 200 samples per class)

./run.sh factory train-gpt --task sparta-intent  # 50 samples, 12 classes = 4/class!

RIGHT: Stay at Tier 2 and harvest more teacher labels first

./run.sh harvest --since 7d  # accumulate shadow labels
./run.sh status              # check sample counts before training

WRONG: Skipping shadow mode and promoting untested models

./run.sh factory promote --task stress-test-grader  # no shadow comparison!

RIGHT: Run shadow mode, verify agreement rate, then promote

./run.sh factory auto-improve --task stress-test-grader
# auto-improve reads shadow agreement rate and decides
