repovine

Repository context assembled and conveyed to coding agents.

The repository knowledge layer

A repository-agnostic core. Across supported languages, frameworks, and infrastructure formats, repovine normalizes repository structure into one queryable model.

Contract boundaries by design. The graph connects repository units through shared code, template, and runtime contracts. These boundaries support repository-scale navigation, dependency impact, runtime flow, and configuration.

Versioned knowledge with explicit ownership. Version-controlled annotations attach intent, invariants, risks, and operational knowledge to graph nodes. Agents and developers author them; repovine checks freshness and structural consistency against repository state.

Together, these layers support intent-driven, context-compiled, contract-verified development. Task intent guides MCP context assembly, and observable claims are checked against repository state.

Checkout-local by design. The live graph and indexes are built from each checkout's working tree and run in memory. Configuration and authored knowledge travel through Git. No database is required.

Benchmarks. Across correctness and restraint tasks drawn from public software repositories, 90% of Repovine runs passed their case-specific diff gate, compared with 10.6% of baseline runs. Explore the results.

Quick start

Start in an existing repository:

npx repovine setup claude # or codex, cursor, all

setup connects the selected client to repovine, adds repovine skills, hooks, and instructions, and builds the repository graph.

The graph model

repovine deterministically derives a graph of cross-unit contracts from repository state. Source and infrastructure plugins translate stack-specific structures into the same vocabulary of packages, modules, exported symbols, templates, runtime resources, and their relationships—so navigation, dependency impact, runtime flow, and configuration work consistently across supported stacks. Explore the design rationale.

How it works

The engine and MCP provide the base workflow. Interactive clients use it directly. For explicit protocol runs, Delivery Protocol adds a structured assignment → result → compliance contract around the same workflow.

Client

In clients such as Claude Code, Codex, or Cursor, the agent uses repovine MCP directly while the developer stays in the loop.

graph LR
  SRC["sources"] --> S1["Stage 1: gather facts"]
  S1 --> S2["Stage 2: build graph"]
  S2 --> ANN["versioned annotations on graph nodes"]
  A["agents and developers"] --> ANN
  S2 --> S3["Stage 3: build search index"]
  ANN --> S3
  S3 --> MCP["MCP tools"]
  ANN --> MCP
  MCP -->|"bounded context"| C["Cursor, Claude Code, or Codex"]

Stage	Input	Output
Stage 1: gather facts	sources	exports, imports, env names, routes, infra
Stage 2: build graph	facts	packages → modules → symbols; infra/template/domain edges
annotations	graph + agent/developer writes	versioned intent, invariants, risks, side effects, and operational constraints
Stage 3: build search index	graph + annotations	token index; optional embeddings to assist fuzzy search
MCP	graph + annotations + index	bounded graph and annotation query results

Delivery Protocol

Delivery Protocol defines the assignment → structured result → compliance report contract. Core owns the schemas, projections, and validators that ground the protocol in observable repository state.

The agent uses MCP to access repository context while it works. The repovine CLI validates the assignment and result and produces the compliance report.

graph LR
  IN["assignment"] --> AV["assignment validation"]
  AV --> A["agent"]
  A <-->|"repository context during the run"| MCP["repovine MCP"]
  A --> R["structured result"]
  AV -->|"validated assignment"| V["repovine compliance validation"]
  R --> V
  S["observable repository state + recorded context"] --> V
  V --> OUT["compliance report"]

repovine validates schema conformance, assignment linkage, and claims it can recompute from the graph, annotations, recorded MCP context, and an optional revision delta. The compliance report covers protocol conformance and repository grounding; behavioral correctness and merge readiness are outside the protocol's scope.

The runnable LangGraph harness demo applies the protocol in an end-to-end agent workflow. Its orchestration topology, sandbox, retries, worktree isolation, and provider behavior are demo-specific implementation choices. See the Delivery Protocol integration guide.

MCP tools

Each tool returns a scoped, structured response.

Query tools, with typical questions for a large repository:

Group	Example question	Tools
Navigate	where is authentication? what is inside the billing package?	search_context, map_context, inspect_node
Runtime	what are the entrypoints? how does an order flow through services?	get_entrypoints, trace_flow
Contracts & config	which consumers are affected by an API change? which environment variables does the worker read?	analyze_dependencies, get_config_surface
Architecture	are there boundary violations or god modules?	analyze_architecture

Maintenance tools service the graph and annotations:

Group	Purpose	Tools
Memory	which nodes are annotated or stale?	get_annotation_status, write_annotation, merge_annotations, validate_annotations, get_annotation_merge_status
Sync	rebuild and check the graph	refresh_context, get_build_status, get_context_session_quality
Domains	tune the domain config	suggest_domains_config
Declines	dismiss reviewed advisory items	decline_advisory (kind: domains-config | carrier-link-gaps)

Setup and CLI

setup adds the following repovine integrations to the workspace while preserving existing configuration and project specialists:

Integration	Included
MCP server	the repovine MCP tools
Skills	repovine-workflow, repovine-annotations, repovine-refresh, repovine-review, repovine-status
Subagents	repovine-repo-explorer, repovine-annotation-writer, repovine-architecture-auditor, repovine-code-reviewer
Hooks	pre-edit boundary notice, post-edit stale-graph notice, session-start "MCP first" reminder
Instructions	AGENTS.md (Cursor uses .cursor/rules)

Command	Goal
npx repovine	run the stdio MCP server outside an IDE/CLI client
npx repovine setup cursor (or claude/codex/all)	add the integrations above, then build the graph
npx repovine build	build the graph
npx repovine status	graph / config / annotation health
npx repovine doctor	diagnose the workspace integration
npx repovine clear	remove repovine-managed workspace files
npx repovine --version · --help	version / help
npx repovine delivery --help	harness/CI Delivery Protocol commands: descriptor, manifests, run brief, validation, and compliance
npx repovine agents --help	harness/CI utilities for repository roles, deterministic orientation, and context-session quality

STDIO is the only supported MCP transport in v1. For remote, devcontainer, WSL, VM, or devbox use, launch the repovine subprocess inside that environment so it runs in the checkout being analyzed.

Supported stacks

Area	Support
Languages	First-class support: TypeScript (JS/JSX via the TS toolchain, needs tsconfig.json); Python partial (backend routes + server-rendered templates)
Frameworks	React, Next.js, Nuxt, SvelteKit, Angular, NestJS, serverless monorepos; Vue/Svelte single-file components (script blocks only)
IaC	Partial, expanding coverage: SAM/CloudFormation, Terraform, Kubernetes, Helm, Dockerfile, docker-compose, Vercel

IaC parsers turn infra files into runtime-resource nodes plus links to the code and images behind them. They cover selected resources and relationships rather than complete format schemas. Coverage is under active development, and extending the existing extractors is a contribution area. Design detail: DESIGN.md.

Requires Node.js 22+ and one indexable root: tsconfig.json, pyproject.toml/setup.py (needs python3), or IaC files. Repositories with supported IaC files can be indexed without a source project; the graph contains infrastructure modules and runtime resources, but no code modules.

Repository files

File / dir	Git	Role
repovine.config.json	commit	main config: graph build and MCP output
repovine.domains.json	commit	logical organization of the repository graph
repovine.annots.json	commit	semantic annotation memory
.repovine/	ignore	local engine cache and workspace state

Defaults work for most TypeScript repositories. Config reference: docs/workspace-files.md.

Status

Preview (0.1.0), usable today and open to contributions. The graph schema and @repovine/plugin-sdk still change.

Contribute

repovine's plugin architecture provides two public producer surfaces for extending language and infrastructure coverage, both exposed by @repovine/plugin-sdk:

Plugin	What it adds
Language source producer	a language: source files → modules, imports, exports, semantic hints
IaC parser	an infra format: files → runtime-resource nodes and links

Built-in and third-party producers share the same public plugin contracts; core validates their output and owns graph identities and ontology. See the plugin guide and runnable Go source plugin, IaC plugin, and other examples.
