DAA-Master: Instructions file for Claude Code

CLAUDE.md

DAA-Master CLAUDE.md is an instructions file for Claude Code from gigayaya/DAA-Master. It costs 794 tokens per session, scanned A, original, Apache-2.0.

A set of Markdown instructions for Claude Code that teaches a three-layer structure for end-to-end test automation. It also describes how to generate, review, and organize code in that structure.

In plain words
What is it for?
Use it when building, reviewing, or reorganizing end-to-end tests with separate test, action, and physical layers.
Why use it?
It gives the coding agent consistent project rules and review checks, reducing confusion about where test logic belongs and how parts should fit together.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions AGENTS.md.

This is gigayaya/DAA-Master's own configuration. It tells Claude Code how to work on DAA-Master itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything DAA-Master configures →

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

DAA-Master CLAUDE.md 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 6d 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.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What This Project Is

This is a Claude Code Skills plugin that teaches Claude the Declarative Action Architecture (DAA) — a strict three-layer separation pattern for E2E automation testing. It is not an application; it contains no runnable code, only Markdown-based skill definitions consumed by Claude Code's skill system.

Architecture

The plugin provides four skills, each in its own directory under plugins/DAA-Master/skills/:

Skill Purpose Entry Point
daa-core Foundational principles, naming conventions, anti-pattern catalog SKILL.md
daa-generate Code generation rules per layer (test, action, physical) with pre-output checklist SKILL.md
daa-review Code review checklist (38 items), severity classification (CRITICAL/WARNING/SUGGESTION), report format SKILL.md
daa-architect Project scaffolding templates, scaling patterns (Builder/Adapter/Strategy/Chain), POM migration guide SKILL.md
daa-install Installs DAA knowledge base into a project, updates CLAUDE.md/AGENTS.md/README.md with DAA rule pointers SKILL.md

Each skill directory has a SKILL.md (the entry point with frontmatter metadata) plus supporting .md files for detailed reference. Skills reference each other: daa-generate, daa-review, and daa-architect all require daa-core as prerequisite context.

The DAA Three-Layer Model

All skills revolve around this strict hierarchy — understand it before editing any skill content:

  • Test Layer ("What"): 100% declarative, zero logic/assertions/system calls. Tests read like plain English.
  • Action Layer ("How" + Verification): The core layer. Every action method must self-verify its own success (the "Self-Verification Mandate"). Split into Atomic (single op + verify) and Composite (orchestrate Atomics into business workflows).
  • Physical Layer ("Mechanism"): Pure "dumb" wrapper around system libraries (HTTP client, Playwright, etc.). Zero assertions, zero business logic, 1-2 line methods.

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.
