Switch model mid-session preserving thinking blocks. Used by /model command and by BRD §6.2 failover when the primary provider rate-limits or fails.
Six-phase ReAct loop (pre-check, thinking, self-critique, action, tool, post). Activates per-workflow via the thinking_level knob in config/workflows.yaml. Replaces standard ReAct for workflows where independent verification of the reasoning improves outcomes.
Mines completed sessions for repeating {tool sequence → outcome} tuples. Scores by frequency × success_rate × novelty. High-scoring tuples become "instincts" — candidate skill seeds — in instincts/pending/.
Walk-back algorithm for the Spec-Auditor subagent. Given a failure at phase N, identifies the earliest phase whose spec, if tightened, would have prevented the failure. Proposes a surgical amendment.
Sessions stored as trees (not lists). /fork creates a branch from any point; /tree navigates; /branch labels a path; /export produces HTML for review. All branches live in one session file under sessions/<project>/<session_id>.json.
Progressive context refinement for subagents. Don't dump everything; retrieve in passes. Start with a list of file paths and one-line abstracts; load full content only when the abstract proves insufficient.

| description | Generate system architecture and UI mockups. Spawns architect (if not already run) and ui-designer concurrently. |
Orchestrates the design phase by running the architect and ui-designer concurrently. If the architect has already been run (via /architect or /build Phase 2), this skill only spawns the ui-designer for mockups.
/design
Check if specs/design/architecture.md exists and project-manifest.json has populated stack fields.
/architect (full interactive flow). Wait for human approval.After architecture approval, check project type:
api-only: Skip UI mockups. Design phase complete.Spawn ui-designer agent to create interactive mockups in specs/design/mockups/.
Present design summary to human for approval.
