bible-to-hld-gather

bible-to-hld-gather is a skill for Claude Code from GoogilyBoogily/googilyboogily-claude-power-tools. It costs 40 tokens per session (2,110 once invoked), scanned A, original, MIT.

A guided preparation process for turning a completed Game Design Bible into high-level design documents, which describe how game features should be built.

In plain words
What is it for?
It loads the bible, lets the user select features, gathers engine and codebase details, and prepares context for generating feature designs.
Why use it?
It helps connect design decisions to technical constraints before implementation starts.

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

bible-to-hld-gather 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 9d 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.

Bible-to-HLD — Context Gathering

Gather all context needed to generate game-development-aware High Level Design documents from a completed Game Design Bible. This skill runs an interactive session to load the bible, present a feature inventory for selection, gather technical context, dispatch research, and compile a structured context file that bible-to-hld-generate consumes.

Input

$ARGUMENTS — bible directory path and optional flags:

  • --features f1,f2,... — comma-separated feature names to skip interactive selection
  • --codebase <path> — path to existing game codebase for technical context

Parse Arguments

Extract from $ARGUMENTS:

  • Bible Directory: First non-flag argument (default: docs/game-design-bible/)
  • Features: --features f1,f2,... — comma-separated list (bypasses Phase 2 interactive selection)
  • Codebase Path: --codebase <path> — path to existing game codebase

Source Integrity Rules

  1. Cite bible sources — every design claim in the context file must trace back to a specific bible section. If no source exists, flag it in Open Questions.
  2. Never invent game design details — if the bible doesn't specify something, leave it as an open question. HLDs translate design into architecture; they do not create new design.
  3. Technical context must come from Phase 3 — engine, platform, and codebase details come only from the Technical Landscape gathered in Phase 3, not from assumptions.

Phase 1: Load Bible Context

Step 1: Validate Bible Exists

Use Glob to check for <bible-dir>/INDEX.md. If it does not exist:

  • Inform the user: "No Game Design Bible found at <bible-dir>. Create one first with /game-design-bible:bible:create."
  • STOP

Step 2: Read Core Bible Files

Read these files — they provide the foundation for every HLD:

  1. <bible-dir>/INDEX.md — check phase completion status
  2. <bible-dir>/DESIGN-PILLARS.md — the supreme court for all design decisions
  3. <bible-dir>/01-core-loop/core-loop.md — the fundamental gameplay loop

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.
