ContextAtlas features

  • get_symbol_context. Returns a symbol’s type, callers, ADR rationale, and related tests in one MCP call.
  • find_by_intent. Searches code by purpose using full-text search over commits, ADRs, and tests.
  • impact_of_change. Shows structural and historical blast radius before editing a symbol.
  • Persistent atlas.json. A committable artifact stored in the repo so every agent reads the same architectural ground truth.
  • Token reduction. Reduces tokens for architectural queries by 45–72% with no quality regression.
  • Multi-language support. Works with TypeScript, Python, Go, and Ruby.

Syrin - Static Contract Analysis for MCP Servers features

  • First-class budget enforcement. Set dollar limits per agent; stop, warn or switch models when the budget is exceeded.
  • Budget-aware persistent memory. Four memory types with decay, import-rank and token-cost awareness, persisting across sessions.
  • Isolated sandbox execution. Run LLM-generated Python, Bash or JavaScript in subprocesses with timeouts and no shared state.
  • 72+ lifecycle hooks. Typed events fire on every LLM request, tool call, memory read, sandbox exec, etc., for observability.
  • Built-in guardrails. PII redaction, prompt-injection detection, content filtering, fact verification and output length limits.
  • Multi-agent orchestration. Swarm topologies and recursive sub-agent spawning share budget, memory and observability.
  • Agent identity & signing. Each agent has a cryptographic Ed25519 identity; messages are signed to prevent impersonation.
  • Token-Oriented Object Notation (TOON). Compact schema format reduces token usage on tool calls by ~40%.
