Three Engines

Observe. Learn. Verify.

Observes

Context Engine

4-layer retrieval with PageRank-scored dependency graphs, tree-sitter AST, and dynamic token budgets. Knows what matters before you ask.

 Learns

Prompt Engine

Loads your constitution and custom prompts. Hashes, versions, and A/B-tests prompt variants so every generation improves over time.

 Verifies

Verify Engine

Syntax guard, parallel deterministic tools, diff-only filter, AI fix, two-stage review. Catches problems before they reach your PR.
