moai-adk: Skill for Claude Code

.claude/skills/moai-workflow-spec/SKILL.md

moai-workflow-spec is a skill for Claude Code from modu-ai/moai-adk. It costs 44 tokens per session (4,328 once invoked), scanned A, original, Apache-2.0.

A workflow for writing software requirements as SPEC documents, including expected behavior, acceptance criteria, and implementation plans. It uses GEARS notation, while keeping older EARS documents readable.

In plain words
What is it for?
It helps define features, document assumptions, write acceptance criteria, and connect planning with implementation and synchronization.
Why use it?
It turns vague requests into clearer requirements that can be checked before and during development.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: names the AskUserQuestion tool; mentions Claude Code.

This is modu-ai/moai-adk's own configuration. It tells Claude Code how to work on moai-adk 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 moai-adk configures →

About the project

MoAI-ADK is a Go-based harness that organizes and verifies Claude Code work across planning, implementation, synchronization, and review stages. Developers use it to structure agentic coding tasks, apply quality gates, and route work across language models, while the catalogue entries extend its workflow with skills, hooks, commands, MCP servers, instructions, and settings.

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

moai-workflow-spec 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.

SPEC Workflow Management

Quick Reference

SPEC Workflow Orchestration using GEARS notation (current) — backed by the EARS legacy backward-compatibility window — for systematic requirement definition and Plan-Run-Sync workflow integration.

Lint behavior canonicalized per the GEARS migration policy.

Core Capabilities:

  • GEARS-Format Specifications (current): Five requirement patterns with the unified compound clause [Where ...][While ...][When ...] The <subject> shall <behavior> and a generalized <subject> (any noun, not only "the system")
  • EARS Legacy Reference: All EARS patterns preserved per the lint engine's backward-compatibility policy to keep pre-v3 SPECs (those authored before GEARS became canonical) readable
  • Requirement Clarification: Four-step systematic process with assumption analysis
  • SPEC Document Templates: Standardized 3-file structure (spec.md / plan.md / acceptance.md)
  • Plan-Run-Sync Integration: Seamless workflow connection
  • Parallel Development: Git Worktree-based SPEC isolation
  • Quality Gates: TRUST 5 framework validation

GEARS Five Patterns (current notation):

Pattern GEARS form (current) EARS form (legacy) Notes
Ubiquitous "The shall " "The system shall " <subject> may be any noun: system, component, service, agent, function, artifact
Event-driven "When , the shall " "WHEN , the system shall " Unchanged trigger semantics
State-driven "While , the shall " "WHILE , the system shall " Unchanged — promoted as a first-class pattern
Capability gate "Where <capability / feature flag / static config>, the shall " "WHERE , the system shall " Reframed — represents capability gate / feature flag / static config (no longer "Optional")
Event-detected (replaces IF/THEN) "When , the shall " IF <condition> THEN <action> [DEPRECATED — use WHEN ] The IF/THEN modality was removed; describe the same intent as a detected event

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.
