bible

bible is a skill for Claude Code, Codex from emilvaintrub/ShowRunner. It costs 99 tokens per session (579 once invoked), scanned A, original, MIT.

A read-only process for producing a combined document of a repository's architecture and actual capabilities, called the Bible.

In plain words
What is it for?
It helps initialize and synchronize the document from source code, design specifications, shipping reports, and security artifacts, then prepare it for an approved merge.
Why use it?
It separates features that are really implemented from features only promised by specifications or reports, while tying claims to evidence.

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 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.

How it starts

The opening of the file, as written. The whole thing — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Bible

Reconcile intent against reality and render one combined architecture and capabilities document. The Bible writes nothing new about the product: every claim traces to a repository path, interface, or named report.

Load

  1. Read ../core/method.md.
  2. Read the active project's .claude/showrunner/config.md.
  3. Read method.md.
  4. Load ../core/merge.md for merge.
  5. Load templates/bible.md for sync.
  6. Load templates/merge.md for merge readiness.

Route

  • init: infer Bible source bindings (Forge spec, Arc ship reports, Sentry sweep, security, and pen-test outputs, and repository-structure hints for component, data-model, and interface extraction) and fill the Bible config section.
  • sync: at an exact commit, extract components, the data model, and interfaces from the repository; reconcile against the Forge spec, Arc ship reports, and Sentry artifacts; apply the evidence rule and the intent-not-shipped drift gate; batch human-owned framing and ambiguous-evidence questions; then render templates/bible.md to bible.output.path.
  • merge: after a clean sync, required smoke, and explicit approval, reuse the shared two-commit ceremony.

Hard Stops

  • Never edit product code, configuration, schema, or risk memory.
  • Never assert an architectural claim or a capability without a citing repository path, interface, or named report.
  • Never list a spec-promised capability the repository does not implement as shipped; record it under Intent-Not-Shipped instead.
  • Never render from a dirty worktree or a tip that does not match the exact commit being documented.
  • Never restate Sentry's full threat model; Part II's security section is a summary with a pointer to the authoritative security document.
  • Never choose audience framing, what counts as a "capability," or resolve ambiguous evidence on the human's behalf.
  • Never merge without explicit human approval and the shared ceremony.
  • Never import facts or wording from another project.

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.
