State-Driven Development Framework - Terraform for your codebase

terra4mice

State-Driven Development Framework

"Software isn't done when it works. It's done when state converges with spec."

terra4mice applies Terraform's mental model to software development. While Terraform manages infrastructure, terra4mice manages living development.

The Problem

In livecoding, this happens:

1. You implement A
2. B breaks A
3. You workaround with C
4. D becomes a TODO
5. Someone says "it works"
6. Weeks later: D never existed

The system doesn't know:

• Which parts of the spec are complete
• Which parts are mocked
• Which parts only exist in your head

The Solution

SPEC (desired state)  ->  What SHOULD exist (declarative YAML)
STATE (current state) ->  What DOES exist (inferred/marked)
PLAN (diff)           ->  spec - state = work to do
APPLY (execution)     ->  Cycles until convergence

Quick Start

# Install
pip install terra4mice

# With deep AST analysis (optional, Python >=3.10)
pip install terra4mice[ast]

# Initialize in your project
cd my-project
terra4mice init

# See what's missing
terra4mice plan

# Auto-detect codebase state
terra4mice refresh

# List resources in state
terra4mice state list

# Mark something as implemented
terra4mice mark feature.auth_login --files src/auth.py

# CI report (JSON)
terra4mice ci --format json

Commands

terra4mice init

Creates spec and state files:

terra4mice init
# Created: terra4mice.spec.yaml
# Created: terra4mice.state.json

terra4mice plan

Shows what's needed to converge:

$ terra4mice plan

terra4mice will perform the following actions:

  + feature.auth_login
      # Resource declared in spec but not in state
  + feature.auth_refresh
      # Resource declared in spec but not in state
  ~ feature.auth_logout
      # Resource is partially implemented

Plan: 2 to create, 1 to update.

With --verbose, plan shows function-level symbol tracking:

$ terra4mice plan --verbose

  ~ module.inference
      # Resource is partially implemented
      Symbols: 10/12 found
        - format_report (missing)
        - validate_config (missing)

terra4mice refresh

Auto-detects codebase state using multiple strategies:

$ terra4mice refresh

Inference Report
============================================================
IMPLEMENTED (5 resources)
  module.models
    Confidence: [##########] 100%
    Files: src/models.py
    Evidence: Explicit files found, AST analysis: 100% match
    Symbols: 12/12 (100%)

PARTIAL (1 resources)
  feature.auth
    Confidence: [######----] 60%
    Symbols: 5/8 (62%)
    Missing: validate_token, refresh_session, logout_handler

MISSING (2 resources)
  feature.payments
  feature.notifications

Summary
  Convergence: 68.8%

Inference strategies (in priority order):

1. tree-sitter AST (with [ast]) - verifies functions, classes, exports against spec attributes
2. stdlib ast - basic Python analysis
3. Regex - Solidity, TypeScript/JavaScript patterns
4. Heuristic - config/docs file size

terra4mice state list

Lists all resources in state:

$ terra4mice state list

feature.auth_login
feature.auth_refresh
module.payment_processor

terra4mice state show <address>

Shows resource details including symbol-level tracking:

$ terra4mice state show module.inference

# module.inference
type     = "module"
name     = "inference"
status   = "implemented"
files    = ["src/terra4mice/inference.py"]
symbols  = 12 (10 implemented, 2 missing)
  InferenceEngine                     class      lines 94-686 (src/terra4mice/inference.py)
  InferenceEngine.infer_all           method     lines 154-178 (src/terra4mice/inference.py)
  InferenceEngine.infer_resource      method     lines 180-245 (src/terra4mice/inference.py)
  format_inference_report             function   lines 719-787 (src/terra4mice/inference.py)
  validate_config                     function   [MISSING]

terra4mice mark <address>

Marks a resource with a status:

# Mark as implemented
terra4mice mark feature.auth_login --files src/auth.py

# Mark as partial
terra4mice mark feature.auth_refresh --status partial --reason "Missing token rotation"

# Mark as broken
terra4mice mark feature.auth_logout --status broken --reason "Tests failing"

terra4mice apply

Interactive apply loop:

$ terra4mice apply

============================================================
Next: + feature.auth_login
      Resource declared in spec but not in state

Attributes: {'endpoints': ['POST /auth/login']}

Action: [i]mplement, [p]artial, [s]kip, [q]uit? i
Files that implement this: src/auth.py, src/routes/login.py
Marked as implemented: feature.auth_login

terra4mice diff

Compare two state snapshots to see what changed:

$ terra4mice diff --old state.json.bak

terra4mice diff
==================================================
  Old: state.json.bak (serial 5)
  New: terra4mice.state.json (serial 8)

Upgraded (3):
  module.inference: partial -> implemented
  module.analyzers: missing -> implemented
  feature.ci: partial -> implemented

Convergence: 45.0% -> 78.3% (+33.3%)

# JSON (machine-readable)

attributes:
  class: StateManager              # verified in classes
  functions: [load, save, list]    # verified in defined functions
  entities: [Resource, State]      # verified in classes/interfaces/types/enums
  exports: [WorkerRatingModal]     # verified in exports (TS/JS)
  imports: [useState, useEffect]   # verified in imports
  commands: [init, plan, refresh]  # substring match in functions
  strategies: [explicit_files]     # substring match in functions+classes

Supported languages: Python, TypeScript/TSX, JavaScript, Solidity.

Roadmap

Phase	Status	Description
1 - MVP CLI	DONE	init, plan, refresh, state, mark, apply, ci, diff
2 - tree-sitter AST	DONE	Multi-language deep analysis, spec attribute verification, symbol tracking
3 - Multi-AI Contexts	PLANNED	Track which AI (Claude, Codex, Kimi) has context on what
4 - CI/CD Integration	DONE	GitHub Action, PR comments, convergence badges
5 - Apply Runner	PLANNED	Interactive apply loop, agent integration
6 - Ecosystem Rollout	PLANNED	Deploy across Ultravioleta DAO projects

Phase 3: Multi-AI Context Tracking (Next)

When multiple AIs work on the same project, each carries its own isolated context. Phase 3 adds a context registry to know which AI has context on what:

terra4mice contexts list
# AGENT          RESOURCE              LAST SEEN    STATUS
# claude-code    module.inference      2min ago     active
# codex          feature.auth_login    1hr ago      stale
# kimi-2.5       feature.frontend      30min ago    active

terra4mice mark module.auth implemented --agent=codex
terra4mice contexts sync --from=claude-code --to=codex

Philosophy

1. State before intention - What exists, not what we want
2. Evidence before perception - Tests, not "I think it works"
3. Convergence before speed - Better slow and correct
4. Clarity before heroism - Visible plan, not magic

Definition of Done

A project is complete when:

$ terra4mice plan

No changes. State matches spec.

Nothing else.
