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

adventure-party 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 10d 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 — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

This is the source repo for Adventure Party (party plugin) — a fantasy-flavored agent-party and experience-system framework for Claude Code, aimed at smart, driven users who weren't full-stack devs before 2024. Everything shipped is markdown (agents, skills, one hook payload) plus a one-command hooks/hooks.json — no runtime code, no build. The repo doubles as its own marketplace (.claude-plugin/marketplace.json).

Dogfooding this repo loads the shipped instructions through the plugin's own SessionStart hook, so the party protocol arrives that way rather than from this file. This project's .claude/ experience files are NOT loaded by anything — read gotchas.md before your first edit, architecture.md before planning or changing how parts fit, decisions.md before choosing between approaches.

Commands

  • Validate manifests (stdlib only — no jq, which is absent on stock macOS/Linux/WSL): python3 -m json.tool .claude-plugin/plugin.json, python3 -m json.tool .claude-plugin/marketplace.json and python3 -m json.tool hooks/hooks.json
  • Validate frontmatter (agents + skills; silence means valid, and a broken description silently unloads the file; needs PyYAML — pip install pyyaml, not bundled with python3 on Debian/Ubuntu): python3 -c "import re,glob,yaml;[yaml.safe_load(re.match(r'^---\n(.*?)\n---\n',open(p,encoding='utf-8').read(),re.S).group(1)) for p in glob.glob('agents/*.md')+glob.glob('skills/*/SKILL.md')]"
  • Check the hook payload against the 9,000 soft budget and the 10,000 character hard cap (past the cap the whole entry is silently relocated to disk; counts code points, so wc -c is wrong here): python3 -c "import sys;n=len(open('hooks/instructions.md',encoding='utf-8').read());print('FAIL' if n>10000 else 'WARN' if n>9000 else 'OK',n,'chars');sys.exit(n>10000)"
  • Hook smoke test (the sentinel phrase is the lantern is lit, in hooks/instructions.md; anything else means the hook didn't inject): claude --plugin-dir . -p 'Quote the sentence containing "lantern" from your instructions, or say NONE.'
  • Dogfood locally: claude --plugin-dir . (agents party:fighter/cleric/wizard/hireling, skills /party:session-zero, /party:long-rest and /party:hire should list)

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.
