blueprint

Project Blueprint

Parameters

Extract these parameters from the user's input:

Parameter	Required	Default	Description
PRD_NAME	No	-	PRD name to create (omit for default charter + main PRD flow)
EXTRA_CONTEXT	No	""	Additional context provided by the user

Environment values (resolve via shell):

• RP1_ROOT: !rp1 agent-tools rp1-root-dir (extract data.root from JSON response)

STATE-MACHINE

stateDiagram-v2
    [*] --> detect
    detect --> charter : needs_charter
    detect --> prd : charter_exists
    charter --> prd : charter_complete
    prd --> [*] : done

On each phase transition, report via:

rp1 agent-tools work update \
  --project "$(pwd)" \
  --feature {FEATURE_ID} \
  --workflow blueprint \
  --run-id {RUN_ID} \
  --step {CURRENT_STATE} \
  --status started

• Generate RUN_ID as a UUID at workflow start; use FEATURE_ID = "blueprint" or derive from PRD_NAME if provided

State Progression Protocol:

1. Report each --step with --status started when you enter that state
2. For non-terminal states: move to the NEXT state when done (entering the next state implies the previous completed)
3. For terminal states (those with → [*] transitions): report --status completed when the step's work finishes
4. On error, transition to the appropriate failure state in the graph

Example sequence (with charter):

--step detect --status started    # entering detect phase
--step charter --status started   # needs charter, entering charter phase
--step prd --status started       # charter done, entering prd phase
--step prd --status completed     # prd done, workflow complete

§CTX

Doc Hierarchy:

1. Charter ({{$RP1_ROOT}}/context/charter.md) - Project-level: problem/context, users, business rationale, scope guardrails, success criteria
2. PRDs ({{$RP1_ROOT}}/work/prds/<name>.md) - Surface-specific: overview, in/out scope, requirements, dependencies, timeline. Inherit from charter, link back, no duplication.

§PROC

Step 1: Mode Detection

Read {{$RP1_ROOT}}/context/charter.md:

Condition	Mode	Message
Not exist	CREATE	"Starting new charter creation. I'll guide you through defining your project vision."
Exists + has ## Scratch Pad	RESUME	"Resuming interrupted charter session. I'll continue from where you left off."
Exists + no scratch pad	UPDATE	"Updating existing charter. I'll ask focused questions about changes you want to make."

Step 2: Initialize Scratch Pad

CREATE - Write charter.md:

# Project Charter: [To Be Determined]

**Version**: 1.0.0
**Status**: Draft
**Created**: {YYYY-MM-DD}

## Scratch Pad

<!-- Interview state - will be removed upon completion -->
<!-- Mode: CREATE -->
<!-- Started: {ISO timestamp} -->

<!-- End scratch pad -->

UPDATE - Edit: append scratch pad after last line:

## Scratch Pad

<!-- Interview state - will be removed upon completion -->
<!-- Mode: UPDATE -->
<!-- Started: {ISO timestamp} -->

<!-- End scratch pad -->

RESUME - No init (scratch pad exists).

Step 3: Charter Interview Loop

question_number = 0 loop:

1. {% dispatch_agent "rp1-dev:charter-interviewer" %} CHARTER_PATH={{$RP1_ROOT}}/context/charter.md, MODE={mode}, RP1_ROOT={{$RP1_ROOT}} {% enddispatch_agent %}

2. Parse JSON response

3. Handle by type:

   next_question: question_number = metadata.question_number topic = map_gap_to_topic(metadata.gaps_remaining[0]) answer = {% ask_user "response.next_question" %} Edit charter.md (insert before <!-- End scratch pad -->): ### Q{N}: {topic} **Asked**: {question} **Answer**: {answer} continue

   success: Write charter sections from response.charter_content Remove "## Scratch Pad" section entirely Update status to "Complete" Output: "Charter complete! Proceeding to PRD creation..." break -> Step 4

   skip: question_number = metadata.question_number topic = from message Edit charter.md: ### Q{N}: {topic} **Skipped**: {message} continue

   error: Output: "Charter interview encountered an error. Scratch pad state preserved for retry." Preserve scratch pad, EXIT (no PRD)

Topic Map:

Gap	Topic
problem	Problem & Context
users	Target Users
value_prop	Value Proposition
scope	Scope
success	Success Criteria
(Q1 CREATE)	Brain Dump

Scratch Pad Edits:

• Insert Q&A: old_string: <!-- End scratch pad --> -> prepend entry
• Remove: match ## Scratch Pad through <!-- End scratch pad -->, replace w/ empty

Step 4: PRD Creation

4.1 PRD Name

PRD_NAME = PRD_NAME || "main"

4.2 Init PRD

Create {{$RP1_ROOT}}/work/prds/{PRD_NAME}.md:

# PRD: {PRD_NAME}

**Charter**: [Project Charter]({{$RP1_ROOT}}/context/charter.md)
**Version**: 1.0.0
**Status**: Draft
**Created**: {YYYY-MM-DD}

## Scratch Pad

<!-- Mode: CREATE -->
<!-- Section: 1 -->
<!-- Started: {timestamp} -->

### Q&A History

<!-- End scratch pad -->

4.3 PRD Loop

PRD_PATH = {{$RP1_ROOT}}/work/prds/{PRD_NAME}.md question_count = 0

loop: {% dispatch_agent "rp1-dev:blueprint-wizard" %} PRD_NAME={PRD_NAME}, EXTRA_CONTEXT={EXTRA_CONTEXT}, RP1_ROOT={{$RP1_ROOT}} {% enddispatch_agent %}

Parse JSON response

next_question | validate: answer = {% ask_user "response.next_question" %} question_count++ Edit PRD (insert before <!-- End scratch pad -->): #### S{section}: {topic} **Asked**: {question} **Answer**: {answer} continue

section_complete: Update section marker: <!-- Section: {N} --> -> <!-- Section: {N+1} --> Write section content to PRD above scratch pad continue

uncertainty: guess = {% ask_user "response.message" %} Add: **Assumption**: {guess} continue

success: Write PRD w/ response.prd_content (removes scratch pad) Output: "PRD created at {PRD_PATH}" break

error: Output: "PRD creation error: {message}" If metadata.missing == "charter": Output: "Please run /blueprint without arguments to create the charter first." break

4.4 Success Output

PRD created!

Created:
- {{$RP1_ROOT}}/work/prds/{PRD_NAME}.md

Next Steps:
- Create features: /rp1-dev:build <feature-id>
- Add more surfaces: /rp1-dev:blueprint mobile-app

§USAGE

Default (charter + main PRD): /rp1-dev:blueprint

Named PRD (requires charter): /rp1-dev:blueprint mobile-app

§NEXT

• /rp1-dev:build <feature-id> - Build specific features
• Features can associate w/ parent PRD for context inheritance
