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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01964 | $0.01964 |
| Opus 5 | $0.00982 | $0.00982 |
| Sonnet 5 | $0.00393 | $0.00393 |
| Haiku 4.5 | $0.00196 | $0.00196 |
Grade A, and why
rpg-marketplace 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 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.
How it starts
The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What this repo is
A Claude Code plugin marketplace (.claude-plugin/marketplace.json), not an application. It ships two plugins that are fundamentally different in kind — don't assume one's conventions apply to the other:
plugins/rpg-vault-guardian— real Node.js code (ESM.mjs) + a test suite. Validates/repairs Obsidian RPG vaults.plugins/rpg-loremaster— pure prompt engineering. No code, no tests: justSKILL.mdfiles,references/*.md, and agent markdown. Nothing here "runs"; it's instructions for the model.
Each plugin has its own .claude-plugin/plugin.json; the root marketplace.json registers both.
Commands
All runnable code lives in rpg-vault-guardian. There is no build step and no linter.
cd plugins/rpg-vault-guardian
npm test # all tests (node --test scripts/test/*.test.mjs)
node --test scripts/test/checks-schema.test.mjs # a single test file
# Run the tools directly (CWD must be a vault root, not this repo):
node scripts/validate.mjs --vault <dir> [--json] [--file <path>] # exit 1 = errors, 2 = broken schema registry
node scripts/init.mjs # scaffold the 14 folders in CWD
node scripts/gen-mocs.mjs --vault <dir> # regenerate _indices/ MOCs
rpg-vault-guardian architecture
scripts/schema.mjs is the single source of truth. It declares ENTITIES (the 12 entity types), COMMON_FIELDS, NON_ENTITY, and IGNORED_TOP. Folder names, required fields, enum values, and which relations may point where all derive from this one object. To add/change an entity type, field, or relation, edit only schema.mjs — folder scaffolding (init), validation, coherence checks, and MOCs all follow automatically. checkSchemaIntegrity() self-validates the registry (relation targets must reference known types; enums must have values), and validate.mjs aborts with exit code 2 if the registry is malformed.
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.

rpg-marketplace CLAUDE.md is an instructions file published in the GitHub repository vstrapasson/rpg-marketplace (2 stars, last pushed 1mo ago), licensed MIT. It adds 1,964 tokens to every session, about $0.0098 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
