rec-praxis-rlm

Procedural Memory + REPL Context for Autonomous AI Agents

A Python package that provides persistent procedural memory and safe code execution capabilities for DSPy 3.0 autonomous agents, enabling experience-based learning and programmatic document manipulation.

Features

• Procedural Memory: Store and retrieve agent experiences with hybrid similarity scoring (environmental + goal embeddings)
• FAISS Indexing: 10-100x faster retrieval at scale (>10k experiences)
• RLM Context: Programmatic document inspection (grep, peek, head, tail) with ReDoS protection
• Safe Code Execution: Sandboxed Python REPL with AST validation and restricted builtins
• DSPy 3.0 Integration: Autonomous planning with ReAct agents and integrated tools
• MLflow Observability: Automatic tracing and experiment tracking
• Production Ready: 99.38% test coverage, comprehensive error handling, backward-compatible storage versioning

Quick Start

Installation

# Basic installation
pip install rec-praxis-rlm

# With all optional dependencies (FAISS, OpenAI, async support)
pip install rec-praxis-rlm[all]

# Development installation
pip install rec-praxis-rlm[dev]

Example 1: Procedural Memory

from rec_praxis_rlm.memory import ProceduralMemory, Experience
from rec_praxis_rlm.config import MemoryConfig

# Initialize memory
config = MemoryConfig(storage_path="./agent_memory.jsonl")
memory = ProceduralMemory(config)

# Store experiences
memory.store(Experience(
    env_features=["web_scraping", "python", "beautifulsoup"],
    goal="extract product prices from e-commerce site",
    action="Used BeautifulSoup with CSS selectors for price elements",
    result="Successfully extracted 1000 prices with 99% accuracy",
    success=True
))

# Recall similar experiences
experiences = memory.recall(
    env_features=["web_scraping", "python"],
    goal="extract data from website",
    top_k=5
)

for exp in experiences:
    print(f"Similarity: {exp.similarity_score:.2f}")
    print(f"Action: {exp.action}")
    print(f"Result: {exp.result}\n")

Example 2: RLM Context for Document Inspection

from rec_praxis_rlm.rlm import RLMContext
from rec_praxis_rlm.config import ReplConfig

# Initialize context
config = ReplConfig()
context = RLMContext(config)

# Add documents
with open("application.log", "r") as f:
    context.add_document("app_log", f.read())

# Search for patterns
matches = context.grep(r"ERROR.*database", doc_id="app_log")
for match in matches:
    print(f"Line {match.line_number}: {match.match_text}")
    print(f"Context: ...{match.context_before}{match.match_text}{match.context_after}...")

# Extract specific ranges
error_section = context.peek("app_log", start_char=1000, end_char=2000)

# Get first/last N lines
recent_logs = context.tail("app_log", n_lines=50)

Example 3: Safe Code Execution

from rec_praxis_rlm.rlm import RLMContext

context = RLMContext()

# Execute safe code
result = context.safe_exec("""
total = 0
for i in range(10):
    total += i * 2
total
""")

if result.success:
    print(f"Output: {result.output}")
    print(f"Execution time: {result.execution_time_seconds:.3f}s")
else:
    print(f"Error: {result.error}")

# Prohibited operations are blocked
result = context.safe_exec("import os; os.system('rm -rf /')")
# Result: ExecutionError - Import statements not allowed

Example 4: Autonomous Planning with DSPy

from rec_praxis_rlm.dspy_agent import PraxisRLMPlanner
from rec_praxis_rlm.memory import ProceduralMemory
from rec_praxis_rlm.config import PlannerConfig, MemoryConfig

# Initialize memory and planner
memory = ProceduralMemory(MemoryConfig())
planner = PraxisRLMPlanner(
    memory=memory,
    config=PlannerConfig(lm_model="openai/gpt-4o-mini")
)

# Add context for document inspection
from rec_praxis_rlm.rlm import RLMContext
context = RLMContext()
context.add_document("logs", open("server.log").read())
planner.add_context(context, "server_logs")

# Autonomous planning
answer = planner.plan(
    goal="Analyze server errors and suggest fixes",
    env_features=["production", "high_traffic", "database"]
)
print(answer)

Security

Sandboxed Code Execution

The SafeExecutor provides multiple layers of security:

1. AST Validation: Blocks imports, eval, exec, file I/O, network access
2. Restricted Builtins: Only safe functions allowed (configurable)
3. Execution Timeout: Prevents infinite loops
4. Output Limiting: Prevents memory exhaustion
5. Code Hashing: Audit trail for all executed code

Blocked operations:

• All imports (import, from ... import)
• Dangerous builtins (eval, exec, __import__, compile, open)
• File system access
• Network access
• Privileged attributes (__class__, __globals__, __dict__)

ReDoS Protection

The DocumentSearcher validates regex patterns to prevent Regular Expression Denial of Service attacks:

• Pattern length limits (<500 chars)
• Nested quantifier detection ((a+)+)
• Excessive wildcard detection (>3 instances of .* or .+)
• Overlapping alternation warnings

Advanced Features

Async Support

import asyncio
from rec_praxis_rlm.memory import ProceduralMemory
from rec_praxis_rlm.rlm import RLMContext

async def main():
    memory = ProceduralMemory(config)
    context = RLMContext(config)

    # Async memory recall
    experiences = await memory.arecall(
        env_features=["python"],
        goal="debug error"
    )

    # Async code execution
    result = await context.asafe_exec("sum(range(1000000))")

asyncio.run(main())

Custom Embedding Providers

from rec_praxis_rlm.embeddings import APIEmbedding
from rec_praxis_rlm.memory import ProceduralMemory

# Use OpenAI embeddings
embedding_provider = APIEmbedding(
    api_provider="openai",
    api_key="sk-...",
    model_name="text-embedding-3-small"
)

memory = ProceduralMemory(
    config,
    embedding_provider=embedding_provider
)

Memory Maintenance

# Compact memory (remove old/low-value experiences)
memory.compact(max_size=1000, min_similarity=0.7)

# Recompute embeddings (after changing embedding model)
new_provider = SentenceTransformerEmbedding("new-model")
memory.recompute_embeddings(new_provider)

Custom Metrics

from rec_praxis_rlm.metrics import memory_retrieval_quality, SemanticF1Score

# Memory retrieval quality metric
score = memory_retrieval_quality(
    example={"env_features": [...], "goal": "...", "expected_success_rate": 0.8},
    prediction=retrieved_experiences
)

# Semantic F1 scoring for DSPy optimization
f1_metric = SemanticF1Score(relevance_threshold=0.7)
score = f1_metric(example, prediction)

MLflow Integration

from rec_praxis_rlm.telemetry import setup_mlflow_tracing

# Enable automatic MLflow tracing
setup_mlflow_tracing(experiment_name="my-agent-experiment")

# All DSPy operations are now traced automatically
planner = PraxisRLMPlanner(memory, config)
result = planner.plan(goal="...", env_features=[...])

# View traces in MLflow UI
# mlflow ui --port 5000
