Introduce Agent Prompt Category as a standalone DocType for organizing and grouping prompt templates. Supports hierarchical categories via parent_category self-link, with icon and color fields for UI display. This is the first step toward treating prompts as first-class reusable artifacts in HUF, preparing for prompt marketplace and library UX. https://claude.ai/code/session_01CotwQ8srHPD1MozVfF3RFM
Introduce Agent Prompt as a first-class reusable artifact in HUF. Implements the immutable version model (Git-like) where each update creates a new row linked via previous_version. Key design decisions: - prompt_group: shared identifier across all versions of a lineage - forked_from: tracks lineage when prompts are forked/copied - is_latest: marks the current head version in each lineage - visibility: Public/App/Private for future marketplace support - is_system: protects HUF-managed prompts from user edits - slug: URL-friendly identifier, auto-generated from title - autoname: hash - supports immutable versioning without name conflicts This model supports version pinning, prompt marketplace, cross-app reuse, diffing, and audit trails. https://claude.ai/code/session_01CotwQ8srHPD1MozVfF3RFM
Add prompt template support to Agent with backward-compatible defaults: - prompt_mode: Select (Local/Template), defaults to "Local" - agent_prompt: Link to Agent Prompt (visible in Template mode) - prompt_version_locked: lock agent to a specific template version - template_version_at_attach: records version at time of attachment - copied_from_prompt: hidden traceability link for detach operations Existing behavior is preserved: all current agents default to "Local" mode and continue using the instructions field directly. The instructions field gains depends_on for Local mode but remains functional for all backend reads. Validation updated to support both modes: Template mode requires agent_prompt link, Local mode requires instructions text. https://claude.ai/code/session_01CotwQ8srHPD1MozVfF3RFM
Add prompt_resolver.py as the single source of truth for resolving an agent's effective prompt. All backend paths (sync runs, streaming, triggers, orchestration) now go through resolve_prompt() instead of reading agent_doc.instructions directly. Resolution rules: - Local mode: returns agent_doc.instructions (backward compatible) - Template mode (unlocked): loads prompt_body from linked Agent Prompt - Template mode (locked): walks the version lineage via prompt_group to find the exact version matching template_version_at_attach Also updates AgentManager.create_agent() and Agent.generate_default_plan() to use resolve_prompt() for consistent behavior. https://claude.ai/code/session_01CotwQ8srHPD1MozVfF3RFM
Add prompt_api.py with server-side operations for the prompt template lifecycle: - create_new_version: immutable versioning — marks old as not-latest, creates new row, auto-updates unlocked agents - fork_prompt: creates independent copy with forked_from lineage - detach_from_template: copies resolved prompt to local, records copied_from_prompt for traceability - save_as_template: creates Agent Prompt from agent's local instructions - attach_template: switches agent to Template mode with optional version locking - get_version_history: returns full version lineage via prompt_group All methods are @frappe.whitelist() and follow Frappe patterns for permissions and error handling. https://claude.ai/code/session_01CotwQ8srHPD1MozVfF3RFM
Update remaining places that read agent_doc.instructions directly to use resolve_prompt() instead: - agent_scheduler.py: scheduled agent runs now resolve templates - orchestrator.py: plan recreation uses resolved prompt - agent.py on_update: detect prompt changes from template switches - agent.py after_insert: pass resolved prompt to orchestration This ensures agents in Template mode work correctly across all execution paths: sync runs, streaming, scheduled triggers, and orchestration planning. https://claude.ai/code/session_01CotwQ8srHPD1MozVfF3RFM

Summary
Introduces a comprehensive prompt template management system for agents, enabling reusable prompt templates with versioning, forking, and flexible prompt mode switching between local and template-based approaches.
Key Changes
New DocTypes
Agent Prompt: Immutable versioned prompt templates with support for:
previous_versionandprompt_groupfieldsAgent Prompt Category: Hierarchical categorization for prompt templates with icon and color support
