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 C, and why

law-verify scanned grade C with 2 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 11d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/verify.sh, tests/run-tests.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

LAW Verify

Run post-build checks on a compiled LaTeX paper. This is invoked automatically after law-build succeeds.

Checks performed

  1. No emdashes — --- is not allowed in body text
  2. All \ref{} resolve — no "Reference undefined" warnings in log
  3. All \cite{} resolve — no "Citation undefined" warnings in log
  4. No \textbf{} mid-paragraph — only \noindent\textbf{Label.} at paragraph start is allowed
  5. No long dashes in prose — --- (em dash) and -- (en dash) are not allowed; hyphens in compound words are fine
  6. Appendix breadcrumbs — WARNING only if an appendix label has no \cref in main body

How to run

bash scripts/verify.sh [paper_root_directory]

If no directory is given, runs in the current directory.

When to prompt user

After running, if humanizer skill (blader-humanizer) is not installed, tell the user:

The humanizer skill is not installed. Install it with:
  curl -sL "https://www.skillhub.club/api/v1/skills/blader-humanizer/install?agents=opencode&format=sh" | bash

What to do with results

  • If all checks pass: report success
  • If any check FAILs: list each failure with file and line number
  • If any check WARNs: list warnings but do not block
  • Do not attempt to fix issues — the user will fix them
Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
