AI Backend Codebase Inventory

Backend codebases hide their shape behind file structure. The team thinks they have 30 routes; the codebase has 47. The middleware chain is undocumented. Auth coverage is inconsistent. Data model relationships are not in any one place.

The /spine-recon skill maps the backend: API routes, middleware chain, authentication, data model, external service dependencies, codebase structure. Assesses code quality and test coverage. Identifies highest-risk areas before changes.

Tonone's /spine-recon skill produces a backend inventory with routes, middleware, auth, data model, dependencies, and risk assessment.

SpineBackend

/spine-recon

Backend reconnaissance: maps all API routes, middleware chain, authentication setup, data model, external service dependencies, and codebase structure. Assesses code quality, test coverage, and identifies the highest-risk areas. Produces a readable inventory before making changes.

SpineBackend

/spine-api

Designs and builds an API contract-first: the interface is defined and agreed before implementation begins. Produces endpoint specs with request and response schemas, validation rules, auth requirements, error codes, and pagination patterns, then implements the full API against that spec.

SpinePlanning

/spine-design

Produces a system design document before implementation begins: component breakdown, data flow diagrams, API contracts between services, failure modes with fallback behavior, and scaling strategy. Written to be reviewed and challenged before any code is written.

ApexPlanning

/apex-takeover

Takes ownership of an inherited or unfamiliar codebase by orchestrating parallel reconnaissance across all 14 specialists simultaneously. Produces a full system map, risk assessment, quick wins list, and recommended roadmap. This is the starting point when joining a project mid-stream.
