phase-1-schema is a skill for Claude Code from ww-w-ai/bkit-claude-code. It costs 28 tokens per session (996 once invoked), scanned A, original, Apache-2.0.

A project vocabulary and data-model planning workflow that defines business terms, the things in the system, and how those things relate.

In plain words
What is it for?
It helps create a glossary, identify entities such as users or payments, map relationships, and document a data schema.
Why use it?
It prevents teams and coding agents from using different words or misunderstanding the shape of the data.

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

phase-1-schema 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 4d 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.

Phase 1: Schema/Terminology Definition

Define terminology and data structures used throughout the project

Purpose

Unify the language of the project. Ensure all team members (or AI) communicate using the same terms and clearly understand data structures.

What to Do in This Phase

  1. Build Glossary: Map business terms + global standards
  2. Identify Entities: Determine what "things" exist
  3. Define Relationships: Relationships between entities
  4. Design Schema: Define data structures

Glossary

Why is it Needed?

Explaining business terms to Claude Code every time is tedious. Creating a glossary allows:

  • Claude to automatically reference for context understanding
  • Team communication consistency
  • Reduced onboarding time for new team members/AI

Term Categories

Category Description Example
Business Terms Internal proprietary terms "Caddy" (golf booking assistant)
Global Standards Industry common or technical standard terms "OAuth", "REST API"
Mapping Business ↔ Global correspondence "Member" = User, "Payment" = Payment

Glossary Template

## Business Terms (Internal Terms)

| Term | English | Definition | Global Standard Mapping |
|------|---------|------------|------------------------|
| Caddy | Caddy | AI assistant that helps book golf rounds | Booking Assistant |
| Round | Round | One 18-hole golf play | Session, Booking |
| Green Fee | Green Fee | Golf course usage fee | Usage Fee |

## Global Standards

| Term | Definition | Reference |
|------|------------|-----------|
| OAuth 2.0 | Authentication protocol | RFC 6749 |
| REST | API architecture style | - |
| UUID | Universal Unique Identifier | RFC 4122 |

## Term Usage Rules

1. Use **English** in code (`Caddy`, `Round`)
2. Use **local language** in UI/docs (Caddy, Round)
3. API responses prioritize **global standards** (`booking_assistant`)

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.
