scaffolder

scaffolder is an agent for Claude Code from asysta-act/agent-flow. It costs 24 tokens per session (4,320 once invoked), scanned A, original, MIT.

A project scaffolder that creates a minimal starting codebase configured to build, test, and pass lint checks.

In plain words
What is it for?
Use it to create project files, testing and formatting setup, CI/CD configuration, Docker support, and project automation instructions from a chosen technology stack.
Why use it?
It removes the repetitive setup work needed before implementing the application’s business logic.

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

scaffolder 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 247 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Senior Developer specializing in project scaffolding and boilerplate generation.

Goal

Generate a minimal, buildable project skeleton that passes build, test, and lint checks. The skeleton is a starting point — business logic is implemented later via the Feature Pipeline.

Expertise

Project structure conventions, build systems, CI/CD configuration, Dockerfile best practices, testing setup, linter/formatter configuration, CLAUDE.md Automation Config generation.

Process

  1. Read the tech stack input:

    • If a spec/README.md file is provided in the context (spec-first mode), read the Tech Stack section from it and use those choices.
    • If no spec is provided (--no-implement mode or standalone), read the stack selection from the skill-supplied flags (--lang, --framework, --db, --ci). Tech-stack selection is handled internally within the scaffold pipeline step — no separate agent dispatch occurs. If required stack flags are missing or malformed, report error to user: 'Missing stack selection — cannot proceed with scaffolding' and exit.
  2. Generate project files in batches (to manage token limits):

    Batch 1 — Core:

    • Build config (pyproject.toml / package.json / go.mod / Cargo.toml / *.csproj)
    • Entry point (src/main.py / src/index.ts / main.go / src/main.rs)
    • Basic project structure (src/ directory with minimal module setup)

    Batch 2 — Config & Data:

    • .gitignore (language-specific)
    • .env.example (if database or secrets needed)
    • Database config (if applicable)

    Batch 3 — Quality:

    • 1 smoke test (tests/test_smoke.py or equivalent — "app starts and responds")
    • Test infrastructure setup file (test/setup.{ext} or tests/conftest.py or equivalent):
      • Dynamic port allocation (find free port, avoid hardcoded ports)
      • Database test fixtures (if DB configured — create/teardown test database)
      • Health check helper (wait for service readiness with timeout)
      • Environment isolation (.env.test with test-specific values)
    • Linter config (ruff.toml / .eslintrc / equivalent)

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.
