Features Overview

Stellarion provides 44 tools organized into community features (free, open source) and Pro features (license-gated).

Code Analysis

Deep understanding of your codebase structure and quality:

• AI Context — Intent-aware context gathering (explain/modify/debug/test) with token budgeting
• Complexity Analysis — Cyclomatic (test paths) and cognitive (readability) scoring per function
• Impact Prediction — Blast radius analysis before modifying, deleting, or renaming code
• Call Graphs — Function call chains with transitive depth
• Dependency Graphs — File/module import relationships

Search & Navigation

Find and navigate code across languages:

• Symbol Search — Hybrid BM25 + semantic search by name or natural language
• Callers / Callees — Trace call chains in both directions
• Import Search — Find all files importing a module
• Signature Search — Search by parameter count, return type, modifiers
• Entry Points — Find main functions, HTTP handlers, CLI commands
• Graph Traversal — Custom traversal with edge and node type filters

Persistent Memory

AI context that survives across sessions:

• Store insights — debugging strategies, architectural decisions, known issues
• Search memories with BM25 + semantic matching
• Context-aware retrieval — get memories relevant to the file or function you're working on
• Invalidation — mark outdated knowledge without losing history

Architecture Analysis Pro

Tools for architects and team leads:

• Codebase Health — Single-call dashboard with score (0-100), grade (A-F), complexity distribution, test coverage, dependency health
• Tech Debt Report — Prioritized debt items with severity and remediation effort estimates
• Change Risk Assessment — Predict risk of file changes for PR review and CI gates
• Coupling Analysis — Afferent/efferent coupling, instability scores
• Dependency Drift — Detect new dependencies and fan-out changes
• API Surface — Catalog public exports, find unused API surface
