- Extracted prompt rendering and formatting utilities from coding-agent to centralized pi-utils package with new API surface (prompt.render, prompt.format, prompt.registerHelper).
- Migrated parseFrontmatter utility from coding-agent to pi-utils package; updated 8 files to import from @oh-my-pi/pi-utils.
- Removed 170-line prompt-format.ts module and consolidated 192 lines of Handlebars helper registrations into pi-utils prompt module.
- Updated 60+ files across coding-agent and typescript-edit-benchmark to use new prompt.render() and prompt.format() API from pi-utils.
- Simplified prompt-templates.ts by delegating core functionality to pi-utils while retaining custom helper registrations (jtdToTypeScript, jsonStringify, etc.).
- Added git branch isolation for autoresearch sessions with automatic branch creation, reuse, and worktree safety checks.
- Added scope definition sections (Files in Scope, Off Limits, Constraints) to autoresearch template for explicit session boundaries.
- Added keybinding matcher utilities for consistent escape/cancel key handling across interactive components.
- Added ASI metadata validation (hypothesis and rollback context) in log_experiment tool for experiment tracking.
- Refactored keybinding logic across 13 components to use centralized matcher functions instead of inline key checks.
- Added task model role configuration enabling dedicated subtask execution with independent model selection.
- Changed default agent model from 'default' to 'pi/task' for independent subtask model configuration.
- Added single-pattern inheritance fallback allowing pi/task agents to inherit session model when unconfigured.
- Refactored model resolution logic into resolveAgentModelPatterns() function with structured fallback handling.
- Added resolveConfiguredModelPatterns() and helper functions for improved model pattern resolution.
- Added streaming text preview during agent specification generation with real-time text delta updates.
- Added `onRequestRender` callback to agent dashboard for async UI re-renders on state changes.
- Improved system prompt preview rendering with text wrapping and line count indicators.
- Enhanced agent creation flow to display generation status hint and reordered spec review before input form.
- Added AI-powered agent creation flow with architect model for generating custom agent specifications from natural language requests.
- Added keyboard shortcuts (N for new agent, R for regenerate) and scope selection (project/user) for agent creation workflow.
- Added model suggestions UI and success/error notices to agent dashboard for improved creation feedback.
- Added system prompts for agent-creation-architect and agent-creation-user roles with 6-step methodology and JSON schema validation.
- Added file persistence with YAML frontmatter for storing agent specifications at project or user scope.
