scaffold

A project-structure generator that turns a product requirements document (PRD)—a written description of what the product must do—into a complete code skeleton.

In plain words
What is it for?
Use it to scaffold a full codebase from an existing PRD before implementing the product’s business logic.
Why use it?
It removes the need to manually create the folders, screens, API endpoints, and data structures described in the requirements. It also links the generated structure back to the documented requirements.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

scaffold scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Transmute Scaffold — Stage 3: Project Code Skeleton Generation

Lead a multi-agent code generation project to produce a complete, development-ready project scaffolding from the existing PRD, with full traceability back to PRD specifications, BRD requirements, and the original Business Plan.

Read the detailed guide at ${CLAUDE_SKILL_ROOT}/references/scaffold-detailed-guide.md for the complete teammate instructions, code generation guidelines, rules-templates processing, and coordination protocol.

Critical Framing: Full-Build Approach

This scaffolding covers the COMPLETE product. Every feature, every screen, every API endpoint, every data entity described in the PRD is scaffolded in this pass. There is no "scaffold the MVP now and add more later." The resulting codebase must be architecturally complete so that the Feature Implementation Orchestrator (Stage 5) can fill in business logic systematically across all features.

Prerequisite Checks

Before proceeding, verify ALL of these conditions. Stop with a clear error message if any fail.

  1. Verify ./plancasting/prd/ directory exists and contains markdown files. If missing: STOP — "Stage 3 requires completed PRD. Run Stages 1-2 first."
  2. Verify ./plancasting/brd/ directory exists and contains markdown files. If missing: STOP — "Stage 3 requires completed BRD. Run Stage 1 first."
  3. Verify ./plancasting/tech-stack.md exists. If missing: STOP — "Stage 3 requires plancasting/tech-stack.md. Run Stage 0 first."
  4. Verify spec validation passed: check plancasting/_audits/spec-validation/report.md for PASS or CONDITIONAL PASS. If FAIL or missing: STOP — "Stage 3 requires spec validation. Run Stage 2B first."
  5. Verify credentials: grep -E 'YOUR_.*_HERE|TODO_.*|CHANGE_ME|PLACEHOLDER|^[A-Z_]+=\s*$' .env.local must return no matches.
  6. Validate credential tiers from plancasting/tech-stack.md:
    • Red tier pipeline infrastructure credentials (TRANSMUTER_ANTHROPIC_API_KEY, E2B_API_KEY, SANDBOX_AUTH_TOKEN) must be present. Exception: If plancasting/tech-stack.md indicates a standalone project (no Transmuter platform), pipeline infrastructure credentials (TRANSMUTER_ANTHROPIC_API_KEY, E2B_API_KEY, SANDBOX_AUTH_TOKEN) may be absent — exclude them from validation.
    • Yellow tier product service credentials should be present (WARN if missing — can be added before Stage 5)

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

scaffold is a skill published in the GitHub repository VoxTechnologies/transmute-framework (4 stars, last pushed 1mo ago), licensed MIT. It adds 86 tokens to every session and 3,650 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
