Sonamu Framework Skills

Claude Code skill for developing projects with the Sonamu framework.

CRITICAL: Ask one question at a time

MUST ask questions one at a time. NEVER overwhelm users with multiple questions.

MUST DO

• One question → wait for user response → next question
• Keep questions concise
• Present choices clearly when options are available

NEVER DO

• List multiple questions at once
• Ask questions alongside long explanations
• Output a checklist of confirmation items all at once

Development Flow

PHASE 0: Project creation and initial setup  (create project → identify domains → auth generate → Users sequence setup)
PHASE 1: Domain logic documentation          (write contract/{domain}/*.contract.md per domain → user confirmation)
PHASE 2: Entity design                       (design with user confirmation)
PHASE 3: Entity creation and migration       (entity.json + migration + cone + scaffolding)
PHASE 4: Testing and API implementation      (contract → Claim → AC → implement, repeat)
PHASE 5: Fixture generation                  (generate with LLM after user approval)
PHASE 6: Frontend development                (proceed in batches with user confirmation)

Full details: see .claude/workflow/project_init.md

Starting Point Determination

Begin from the PHASE that matches the user's instruction. Do not always start from PHASE 0.

User instruction	Starting PHASE	Prerequisites to verify
"Create a new project"	PHASE 0	—
"Write contract" / "Analyze domain"	PHASE 1	Domain list identified
"Add entity" / "Create entity"	PHASE 2	Project exists, dev server running, read contract/*/.contract.md, PHASE 1 complete
"Write tests" / "Implement API"	PHASE 4	entity.json exists, migration complete, scaffolding complete
"Generate fixtures"	PHASE 5	Tests passing, cone.note exists
"Develop frontend"	PHASE 6	API implementation complete, contract/*/.contract.md reviewed

Mid-entry rules:

1. If contract/**/*.contract.md and skills/project/architecture.md exist, read them first.
2. Verify prerequisites for the target PHASE.
3. If prerequisites are not met, inform the user and begin from the required step.
4. Within a PHASE, follow the numbered steps in .claude/workflow/project_init.md in order. Do not skip any step or merge steps on your own judgment.

Project Document System

CRITICAL: Read these before starting any task

Before starting any project task, always read the following documents.

contract/
└── {domain}/
    └── {domain}.contract.md  # PHASE 1: domain rules + decision rationale (permanent; update alongside code changes)

.claude/skills/project/
└── architecture.md      # entity design + system architecture

tmp/claims/              # in-progress Claim YAML (discard after completion)

Code is the ground truth. *.contract.md records the rationale behind code decisions — it is not a spec that precedes the code. When code and *.contract.md conflict, the code takes precedence.

Domain *.contract.md

Documents domain rules in a cohesive form and captures decision rationale that cannot be inferred from code alone.

# {Domain} Business Logic

## Rules

- Refunds allowed only within 7 days of payment [Rationale: PG provider policy]
- Order status transitions: pending → confirmed → shipped → completed

## Workflow

1. ...

Two development paths:

• New: write *.contract.md → Claim → AC (test name) → implement (TDD)
• Change: modify code → register Claim → verify/update *.contract.md (record change rationale)

Update rules:

• When code changes, check affected domain rules and update *.contract.md together
• Record the reason and decision rationale — this keeps *.contract.md alive

architecture.md

When: designing entities or discussing system architecture Content: entity structure and relationships, database schema, system component structure

Safe after compacting

Documents are persisted as files, so project context is preserved even when the conversation is compacted.
