description

Use this skill when scaffolding a new project or feature from context (PRD, implementation plan, project directory, or free-text description). Transforms context into a deployed Bundle of artifacts via structured Intent extraction and ranked artifact search. Invoked by /scaffold:project and /scaffold:feature commands. Trigger phrases: 'scaffold my project', 'set up my Codex environment', 'create a starter bundle', 'scaffold from my PRD', 'build my artifact bundle', 'feature scaffold', 'scaffold feature'. Requires a seeded local collection (≥20 artifacts) and a running SkillMeat API.

Project Scaffolder Skill

Transforms project context (PRDs, directories, or free text) into a deployed Bundle of Codex artifacts via a five-step pipeline: analyze → curate → preview → confirm → deploy.

Quick Start

Mode	Command	Use When
Project mode	/scaffold:project	Starting a new project; whole-project Bundle needed
Feature mode	/scaffold:feature	Adding a feature to an existing project; avoids re-adding deployed artifacts

Workflow Pipeline

/scaffold:project  OR  /scaffold:feature
         │
         ▼
1. ANALYZE — project-analyzer (Sonnet 4.6)
   • Reads context (PRD path / directory / free text, up to 10K tokens)
   • Emits Intent Set YAML (capabilities, stacks, confidence scores)
         │
         ▼ (if aggregate_confidence < 0.65 OR ≥2 high-priority intents < 0.5 confidence)
2. INTERVIEW — Opus asks ≤3 targeted questions
   • Questions target lowest-confidence high-priority intents
   • Answers fed back to analyzer for a refined Intent Set
         │
         ▼
3. CURATE — artifact-curator (Sonnet 4.6) [Phase 2]
   • Three-leg search: local match, local metadata, marketplace
   • Deterministic ranking: 0.5×semantic + 0.3×metadata + 0.2×marketplace
   • De-duplicates by artifact_uuid; caps at 5 candidates/intent
   • Removes candidates with final_score < 0.3
         │
         ▼
4. PREVIEW — shown to user
   • Table: type | name | source | confidence | intent
   • User can confirm all / remove items / abort
         │
         ▼
5. DEPLOY — on confirmation
   • POST /api/v1/bundles → create Bundle
   • POST /api/v1/bundles/{id}/members → add artifacts (alphabetical: type asc, name asc)
   • skillmeat scaffold --bundle <id> --project <path>  [if deploy target specified]
   • Intent Set YAML persisted alongside Bundle manifest

Subagent Definitions

project-analyzer

• Definition: .Codex/agents/scaffolder/project-analyzer.md
• Model: Sonnet 4.6, permissionMode: plan
• Input: PRD file path, implementation plan path, project directory path, or free-text description
• Processing: Reads context (truncates at 10K tokens with warning); extracts tech stack, frameworks, architectural patterns, domain concepts, required capabilities
• Output: Intent Set YAML with confidence scores per intent and aggregate score
• Invoked: Once per scaffold run, before curator

artifact-curator

• Definition: .Codex/agents/scaffolder/artifact-curator.md
• Model: Sonnet 4.6, permissionMode: plan
• Input: Intent Set YAML (from analyzer)
• Processing: Three-leg search (local match, metadata, marketplace); merge + rank; de-duplicate; filter
• Output: Ranked artifact candidate list with confidence and source intent traceability
• Invoked: After analyzer (and interview, if triggered); Phase 2 full implementation

Quick Reference

scaffold_run_id: "scaf_20260407_abc123"      # unique per run
generated_at: "2026-04-07T14:32:00Z"         # ISO 8601
scope_variant: "whole-project"               # whole-project | feature | artifact-type-scoped
source_summary: "FastAPI + React + PostgreSQL PRD"
intents:
  - id: "int_001"
    capability: "python-backend"             # see CAPABILITY_ENUM in intent_schema.py
    stack: "fastapi"                         # optional
    confidence: 0.95                         # 0.0–1.0
    source: "PRD §2 — Tech Stack"
    priority: high                           # high | medium | low
aggregate_confidence: 0.75                   # weighted mean by priority
interview_triggered: false

Aggregate Confidence Formula

weights: high=1.0, medium=0.6, low=0.3
aggregate = sum(confidence[i] × weight[priority[i]]) / sum(weight[priority[i]])

Interview Trigger

Triggers when:

• aggregate_confidence < 0.65, OR
• count(intents where confidence < 0.5 AND priority == high) >= 2

Generates ≤3 targeted questions (one per lowest-confidence high-priority intent). Pure Python logic: skillmeat/core/scaffolder/interview.py

API Integration

The skill uses only existing stable endpoints:

Leg	Endpoint	Purpose
Semantic search	GET /api/v1/match?q=<capability stack>&limit=10	TF-IDF ranked matches
Metadata search	GET /api/v1/artifacts?tags=<capability>&type=<types>&limit=50	Tag + type filter
Marketplace	GET /api/v1/marketplace/listings?q=<query>&limit=10	Optional (feature flag)
Bundle create	POST /api/v1/bundles	Creates Bundle with scaffold metadata
Bundle members	POST /api/v1/bundles/{id}/members	Adds ranked artifacts

Feature flag: SCAFFOLD_MARKETPLACE_ENABLED (default: true)

Scope Variants

Variant	Command	Behavior
whole-project	/scaffold:project	Full artifact scan; no exclusion of existing artifacts
feature	/scaffold:feature	Reads deployed .Codex/ inventory; excludes already-present artifacts
artifact-type-scoped	Either + --types	Restricts curator search to specified artifact types

Dry-Run Mode

Pass --dry-run to suppress Bundle creation and file writes. Preview is shown; no API writes occur. Useful for evaluating recommendations before committing.

Prerequisites

• SkillMeat API running (skillmeat web dev)
• Collection seeded with ≥20 artifacts for non-trivial results
• For marketplace: SCAFFOLD_MARKETPLACE_ENABLED=true (default)
