Specialized Subagents
Role-based delegation: dedicated subagents for planning, coding, review, security audits, and deployment.
Chained Skill Graph
Skills connect into a guarded delivery loop — Brainstorm → Plan → Cook → Review → Ship — with deterministic gates.
Context & Safety Hooks
Just-in-time guardrails: pre-tool hooks prompt for approval before sensitive operations and inject project rules.
Harness-Native Adapters
Deep runtime integration with Claude Code, Codex, and Cursor, with native tool definitions and model routing.
1 · Brainstorm
Exhaust trade-offs, surface edge cases, and define non-goals before touching code.
2 · Advise
Autonomous Fable-tier counsel reframes requirements, surfaces anti-patterns, and scores options.
3 · Plan
Generates verifiable phase contracts, dependency DAGs, and interactive artifacts.
4 · Cook
Tests-first execution, worktree isolation, and zero-breakage modularization.
5 · Code Review
Multi-perspective quality audit, regression tests, and security scans.
6 · Ship
Conventional commit splitting, PR verification, and CI convergence watch.
