LogicStamp: Deterministic Context for AI-Assisted Development

The Problem: Why LLMs Struggle with Real Codebases

LLMs are bad at understanding real codebases.

The way we provide context today is fragmented, lossy, and hard to reason about:

  • Pasted files - incomplete, out of context
  • Partial trees - missing critical relationships
  • Large snapshots - overwhelming, hard to navigate
  • Vague summaries - imprecise, unreliable

This approach solved part of the problem, but the real breakthrough came when I wired deterministic context into a live AI workflow using the Model Context Protocol (MCP).


The Current State: What's Broken

Most AI-assisted coding workflows rely on some variation of:

  • Pasting files or partial code into chat
  • Including entire folder snapshots
  • "Just include the folder" assumptions
  • Implicit assumptions about project structure

This breaks down quickly:

  • Context gets truncated - important details are lost
  • Relationships are lost - component dependencies become unclear
  • Results vary between runs - non-deterministic behavior
  • CI/automation becomes impossible - no stable foundation

You can often feel that the model is missing something - but you can't point to a stable, inspectable source of truth for what it actually knows about your codebase.


The Solution: Structured Context Instead of Snapshots

Instead of snapshots, I wanted structured context.

So I built LogicStamp, a CLI that statically analyzes a React/TypeScript project and produces deterministic, machine-readable context bundles.

Rather than shipping raw files, it extracts structure:

  • Components - with their contracts and APIs
  • Hooks - dependencies and state management
  • Props - type signatures and relationships
  • Dependencies - explicit component graphs
  • Relationships - how pieces connect

The output is JSON, designed to be:

  • Stable across runs - deterministic output
  • Machine-readable - structured data, not prose
  • Human-inspectable - clear, organized format

From CLI to Workflow: The MCP Integration

A CLI alone still leaves one question unanswered:

How does an AI assistant actually consume this context?

That's where LogicStamp MCP comes in.

The Workflow

┌─────────────────┐
│  AI Assistant   │
│  (Claude/Cursor)│
└────────┬────────┘
         │
         │ Queries via MCP
         │
         ▼
┌─────────────────┐
│  LogicStamp MCP │
│     Server      │
└────────┬────────┘
         │
         │ Invokes CLI
         │
         ▼
┌─────────────────┐

└────────┬────────┘

         ▼
┌─────────────────┐
│ Context Bundles │
│   (JSON)        │
└─────────────────┘

The MCP server invokes the LogicStamp CLI on demand.

The CLI statically analyzes the codebase and generates deterministic context bundles.

The MCP then exposes that structured context to AI tools at runtime.

Instead of pasting files, the model queries explicit, regenerated structure.


What This Enables: The Full Workflow Benefits

Once context is deterministic and queryable:

Reproducibility

  • Results become reproducible - same input, same output
  • Workflows don't drift - consistent behavior over time

Inspectability

  • AI behavior becomes inspectable - you can see exactly what context was used
  • Stable source of truth - no guessing what the model knows

Automation

  • CI pipelines become possible - automated testing of AI workflows
  • Tools stop relying on implicit assumptions - explicit contracts instead

Better Understanding

  • The model no longer guesses - it consumes structured data
  • Relationships are explicit - dependency graphs, not assumptions

What LogicStamp Does: End-to-End

Zero-Config CLI

stamp context          # Generate context bundles
stamp context style    # Include style metadata (Tailwind, SCSS, etc.)
Enter fullscreen mode Exit fullscreen mode

Static Analysis

  • Uses TypeScript AST for accurate parsing
  • Extracts component contracts, props, hooks, dependencies
  • Builds explicit dependency graphs

Deterministic Output

  • Stable JSON format
  • Consistent across runs
  • Version-controlled friendly

AI-Ready Context Bundles

  • Optimized for LLM consumption
  • Structured, not prose
  • Complete component contracts

MCP Server Integration

  • Exposes context to AI tools at runtime
  • On-demand regeneration
  • Query-based access

No magic, no agents, no memory tricks - just structure and contracts.


Why Deterministic Context Matters

When context is deterministic:

For Development

  • Results are reproducible - same question, same answer
  • Workflows don't drift - consistent behavior over time
  • Debugging becomes possible - you can inspect what the model saw

For Automation

  • CI pipelines can reason about structure - automated testing of AI workflows
  • Version control becomes meaningful - track changes to structure, not just code
  • Integration becomes reliable - stable APIs for tooling

For AI

  • AI becomes a consumer of systems - structured data, not guessing
  • No more implicit assumptions - explicit contracts
  • Better understanding - complete picture, not fragments

Even outside of AI, having a stable structural representation of a codebase turns out to be useful in surprising places:

  • Documentation generation
  • Architecture analysis
  • Dependency tracking
  • Refactoring support

Open Source
