Use when the user wants to build, fix, tweak, refactor, add or modify any code, component or feature.'
 ---
 
-# Quick Dev New Preview Workflow
+```
+python render.py
+```
 
-**Goal:** Turn user intent into a hardened, reviewable artifact.
-
-**CRITICAL:** If a step says "read fully and follow step-XX", you read and follow step-XX. No exceptions.
-
-## READY FOR DEVELOPMENT STANDARD
-
-A specification is "Ready for Development" when:
-
-- **Actionable**: Every task has a file path and specific action.
-- **Logical**: Tasks ordered by dependency.
-- **Testable**: All ACs use Given/When/Then.
-- **Complete**: No placeholders or TBDs.
-
-## SCOPE STANDARD
-
-A specification should target a **single user-facing goal** within **900–1600 tokens**:
-
-- **Single goal**: One cohesive feature, even if it spans multiple layers/files. Multi-goal means >=2 **top-level independent shippable deliverables** — each could be reviewed, tested, and merged as a separate PR without breaking the others. Never count surface verbs, "and" conjunctions, or noun phrases. Never split cross-layer implementation details inside one user goal.
-  - Split: "add dark mode toggle AND refactor auth to JWT AND build admin dashboard"
-  - Don't split: "add validation and display errors" / "support drag-and-drop AND paste AND retry"
-- **900–1600 tokens**: Optimal range for LLM consumption. Below 900 risks ambiguity; above 1600 risks context-rot in implementation agents.
-- **Neither limit is a gate.** Both are proposals with user override.
-
-## Conventions
-
-- Bare paths (e.g. `step-01-clarify-and-route.md`) resolve from the skill root.
-- `{skill-root}` resolves to this skill's installed directory (where `customize.toml` lives).
-- `{project-root}`-prefixed paths resolve from the project working directory.
-- `{skill-name}` resolves to the skill directory's basename.
-
-## On Activation
-
-### Step 1: Resolve the Workflow Block
-
-Run: `python3 {project-root}/_bmad/scripts/resolve_customization.py --skill {skill-root} --key workflow`
-
-**If the script fails**, resolve the `workflow` block yourself by reading these three files in base → team → user order and applying the same structural merge rules as the resolver:
-
-1. `{skill-root}/customize.toml` — defaults
-2. `{project-root}/_bmad/custom/{skill-name}.toml` — team overrides
-3. `{project-root}/_bmad/custom/{skill-name}.user.toml` — personal overrides
-
-Any missing file is skipped. Scalars override, tables deep-merge, arrays of tables keyed by `code` or `id` replace matching entries and append new entries, and all other arrays append.
-
-### Step 2: Execute Prepend Steps
-
-Execute each entry in `{workflow.activation_steps_prepend}` in order before proceeding.
-
-### Step 3: Load Persistent Facts
-
-Treat every entry in `{workflow.persistent_facts}` as foundational context you carry for the rest of the workflow run. Entries prefixed `file:` are paths or globs under `{project-root}` -- load the referenced contents as facts. All other entries are facts verbatim.
-
-### Step 4: Load Config
-
-Load config from `{project-root}/_bmad/bmm/config.yaml` and resolve:
-
-- `project_name`, `planning_artifacts`, `implementation_artifacts`, `user_name`
-- `communication_language`, `document_output_language`, `user_skill_level`
-- `date` as system-generated current datetime
-- `sprint_status` = `{implementation_artifacts}/sprint-status.yaml`
-- `project_context` = `**/project-context.md` (load if exists)
-- CLAUDE.md / memory files (load if exist)
-- YOU MUST ALWAYS SPEAK OUTPUT in your Agent communication style with the config `{communication_language}`
-- Language MUST be tailored to `{user_skill_level}`
-- Generate all documents in `{document_output_language}`
-
-### Step 5: Greet the User
-
-Greet `{user_name}`, speaking in `{communication_language}`.
-
-### Step 6: Execute Append Steps
-
-Execute each entry in `{workflow.activation_steps_append}` in order.
-
-Activation is complete. Begin the workflow below.
-
-## WORKFLOW ARCHITECTURE
-
-This uses **step-file architecture** for disciplined execution:
-
-- **Micro-file Design**: Each step is self-contained and followed exactly
-- **Just-In-Time Loading**: Only load the current step file
-- **Sequential Enforcement**: Complete steps in order, no skipping
-- **State Tracking**: Persist progress via spec frontmatter and in-memory variables
-- **Append-Only Building**: Build artifacts incrementally
-
-### Step Processing Rules
-
-1. **READ COMPLETELY**: Read the entire step file before acting
-2. **FOLLOW SEQUENCE**: Execute sections in order
-3. **WAIT FOR INPUT**: Halt at checkpoints and wait for human
-4. **LOAD NEXT**: When directed, read fully and follow the next step file
-
-### Critical Rules (NO EXCEPTIONS)
-
-- **NEVER** load multiple step files simultaneously
-- **ALWAYS** read entire step file before execution
-- **NEVER** skip steps or optimize the sequence
-- **ALWAYS** follow the exact instructions in the step file
-- **ALWAYS** halt at checkpoints and wait for human input
-
-## FIRST STEP
-
-Read fully and follow: `./step-01-clarify-and-route.md` to begin the workflow.
+Then follow the instruction it prints to stdout.
