Deconnected builds one evidence graph across frontend code, API routes, backend modules, workers, Docker services, SQL/ORM references and database tables. It helps identify safe extraction seams, probable legacy elements and refactoring risks before code is moved or removed.

Deconnected is intentionally conservative. A missing reference is evidence for investigation, not automatic permission to delete a table, endpoint or module.

Capabilities

• static scanning of Python, JavaScript, TypeScript, SQL, PHP, Go, Java and Kotlin files;
• Python route, import, table and embedded-SQL analysis with LibCST;
• SQL table extraction with sqlglot and a lower-confidence fallback parser;
• Docker Compose and Dockerfile dependency scanning;
• optional database-schema reflection through SQLAlchemy;
• import and correlation of TestQL runtime topology;
• table usage classification from static, runtime and test evidence;
• extraction-candidate discovery from graph cohesion and boundary edges;
• optional integrations with code2llm, code2logic, redup, regix, vallm and toonic;
• constrained refactoring plans, optional LiteLLM/OpenRouter refinement and isolated Claude Code execution;
• patch-scope policy, forbidden-operation checks, repository snapshots and validation reports.

Requirements

• Python 3.10 or newer;
• Git for isolated refactoring simulations;
• optional Docker/TestQL/runtime services when those integrations are used;
• optional claude executable for Claude Code execution.

Installation

Core package and development tools:

python -m pip install -e ".[dev]"

Browser and TestQL support:

python -m pip install -e ".[dev,gui,testql]"
playwright install chromium

LiteLLM/OpenRouter planning:

python -m pip install -e ".[dev,llm]"

Full optional ecosystem:

python -m pip install -e ".[dev,gui,testql,ecosystem,llm]"

External ecosystem packages are optional adapters. A missing adapter does not block the core scan.

Quick start

1. Build an evidence graph

deconnected scan . --out .deconnected/graph.json

With a TestQL topology and reflected database schema:

deconnected scan . \
  --testql-topology .testql/topology.json \
  --database-url "$DATABASE_URL" \
  --out .deconnected/graph.json

2. Inspect usage and extraction candidates

deconnected report .deconnected/graph.json
deconnected table-usage .deconnected/graph.json
deconnected classify-tables .deconnected/graph.json
deconnected seams .deconnected/graph.json

Machine-readable table classifications:

deconnected classify-tables .deconnected/graph.json --json-output

3. Create frontend checks from TestQL topology

deconnected generate-frontend-tests \
  .testql/topology.json \
  --out .deconnected/generated-web.testql.toon.yaml

4. Create a constrained refactoring plan

deconnected plan-refactor \
  .deconnected/graph.json \
  "extract protocol audit feature" \
  --out .deconnected/refactor-plan.json

5. Verify or simulate the plan

deconnected verify-refactor . .deconnected/refactor-plan.json

Claude Code simulation inside an isolated worktree:

deconnected simulate-refactor \
  . \
  .deconnected/refactor-plan.json \
  --keep-worktree

Table classifications

• actively_used — runtime SQL evidence exists;
• statically_reachable — reachable from a GUI/API/job/service entrypoint and referenced outside tests;
• statically_referenced — referenced, but no complete entrypoint path was proven;
• test_only — discovered references are limited to tests;
• probable_legacy — no static, runtime or test evidence was found.

probable_legacy is a review candidate. Before deletion, verify migrations, production traffic, external consumers, scheduled jobs, manual scripts, backups and rollback procedures.

LLM-assisted planning with LiteLLM/OpenRouter

Set the provider key supported by the selected LiteLLM model. For OpenRouter:

export OPENROUTER_API_KEY="..."

Generate and refine a plan:

deconnected plan-refactor \
  .deconnected/graph.json \
  "split protocol audit into a bounded package" \
  --provider litellm \
  --model openrouter/deepseek/deepseek-chat \
  --out .deconnected/refactor-plan.json

The deterministic plan is created first. The model may refine it, but the returned object must validate against the RefactorPlan Pydantic schema.

Current limitation: CLI budget parameters are not exposed yet. BudgetPolicy exists in the Python API and uses conservative defaults.

Claude Code execution

The Claude Code adapter runs claude -p with a restricted tool list:

Read, Glob, Grep, Edit,
Bash(pytest:*), Bash(npm test:*), Bash(git diff:*), Bash(ruff:*)

The simulation:

1. refuses plans with blockers;
2. creates an isolated Git worktree and branch;
3. asks Claude Code to apply only the approved plan;
4. records snapshots before and after;
5. evaluates changed paths and forbidden operations;
6. runs the validation matrix only when policy passes;
7. saves the binary Git patch and reports.

The current branch is not edited directly.

Refactoring artifacts

Each simulation writes to:

.deconnected/runs/<plan-id>/

Artifacts:

agent-result.json
policy.json
snapshot-before.json
snapshot-after.json
snapshot-diff.json
verification.json
patch.diff

See docs/ARTIFACTS.md for field-level interpretation.

Optional ecosystem integrations

Check availability:

deconnected integrations

Run installed analyzers:

deconnected ecosystem-scan . \
  --target http://localhost:8100 \
  --tools testql,code2llm,redup,regix,vallm,toonic \
  --out .deconnected/ecosystem

The command writes .deconnected/ecosystem/manifest.json with availability, status and produced artifacts.

Safety model

Default assumptions:

• no automatic database table drops;
• no remote pushes;
• no Git history rewriting;
• no direct work on the current branch;
• every plan contains allowed_paths and forbidden_operations;
• a scope or policy violation blocks acceptance;
• tests passing cannot override a blocked patch policy;
• a patch is retained for review even when blocked.

Development

Run the complete test suite:

PYTHONPATH=src pytest -q

Compile Python sources:

python -m compileall src

Lint:

ruff check src tests

Status

Version 0.6.1 is an experimental refactoring-analysis tool. Review generated plans and patches before merging. Database-destructive changes and public API changes require explicit human approval outside the current automated flow.
