> Dynamic multi-repo and monorepo awareness for Claude Code. Analyze workspace topology, track API contracts, and maintain cross-repo context.
When you have separate frontend/backend repos (or monorepo with multiple apps), Claude Code operates in isolation. It doesn't know:
This leads to:
Instead of static manifests that get stale, Claude dynamically analyzes the workspace and generates context artifacts that stay fresh through hooks.

Determine workspace structure:
markdown## Discovery Checklist 1. [ ] Identify workspace root 2. [ ] Classify workspace type (monorepo/multi-repo/hybrid/single) 3. [ ] List all modules/apps/packages 4. [ ] Detect tech stack per module 5. [ ] Identify entry points per module
Module Detection Pattern:
workspace-root/
├── apps/ → Application modules
│ ├── web/ → Frontend app
│ └── api/ → Backend app
├── packages/ → Shared packages
│ ├── ui/ → Component library
│ ├── types/ → Shared types
│ └── db/ → Database layer
├── services/ → Microservices
└── libs/ → Internal librariesFor each module, map:
1. Internal Dependencies
bash# TypeScript/JavaScript grep -r "from ['\"]@" --include="*.ts" --include="*.tsx" | head -50 grep -r "workspace:" package.json # Python grep -r "from \." --include="*.py" | head -50
2. API Relationships
bash# Find API calls grep -rE "fetch|axios|httpx|requests\." --include="*.ts" --include="*.py" | \ grep -E "/api|localhost|127\.0\.0\.1" | head -30
3. Database Connections
bash# Find DB access patterns grep -rE "prisma|drizzle|sqlalchemy|sequelize|typeorm" --include="*.ts" --include="*.py"
Identify and parse API contracts:
| Contract Type | Detection | Extraction | |---------------|-----------|------------| | OpenAPI | openapi.json, swagger.yaml, /docs endpoint | Parse paths, schemas | | GraphQL | schema.graphql, .gql, /graphql endpoint | Parse types, queries, mutations | | tRPC | trpc router files, @trpc/ imports | Parse router definitions | | Protobuf | .proto files | Parse services, messages | | TypeScript | Shared .d.ts, exported interfaces | Parse exported types | | Pydantic | schemas/, models/ with BaseModel | Parse model definitions | | Zod | schemas/ with z.object | Parse schema definitions |
Contract Source Priority:
Identify files Claude MUST know about for each context:
| Category | Detection Pattern | Token Priority | |----------|-------------------|----------------| | Route definitions | **/routes/**, **/api/**, @app.get, @router | HIGH | | Type definitions | **/types/**, *.d.ts, schemas/, models/ | HIGH | | Config | .env.example, config/, settings.py | MEDIUM | | Entry points | main.ts, index.ts, app.py, server.py | MEDIUM | | API clients | **/api/client*, **/lib/api* | HIGH | | Database schema | schema/, migrations/, prisma/schema.prisma | MEDIUM | | Tests | __tests__/, *_test.py, *.spec.ts | LOW (on-demand) |

markdown## Multi-Repo Access Protocol WHEN accessing files from another repo: 1. Use relative paths from workspace root 2. Read-only access (never modify other repos) 3. Cache contract files locally in _project_specs/workspace/cache/ 4. Log cross-repo reads in decisions.md BEFORE making cross-repo changes: 1. Document the change in BOTH repos' decisions.md 2. Create linked todos in BOTH repos 3. Implement in dependency order (shared → backend → frontend)

workspace.md calls existing-repo.md analysis for each module:
markdown## Module Analysis Delegation For each module in workspace: 1. Run existing-repo analysis on that module 2. Extract: tech stack, conventions, guardrails status 3. Aggregate into TOPOLOGY.md 4. Don't duplicate - reference existing-repo output
markdown## Session State Integration Workspace context files are part of session state: - TOPOLOGY.md → structural context (rarely changes) - CONTRACTS.md → API context (check freshness each session) - KEY_FILES.md → loading guidance (static reference) On session start: 1. Load _project_specs/workspace/*.md into context 2. Check contract freshness 3. Advise if sync needed
markdown## Cross-Repo Review Checks When reviewing code that touches contracts: 1. Check if change affects other modules 2. Verify contract consistency 3. Flag if CONTRACTS.md needs update 4. Warn about breaking changes Add to review output: ### 🔗 Cross-Repo Impact - [ ] This change affects: apps/web (API client) - [ ] Contract update needed: Yes - [ ] Breaking change: No
