Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00104 | $0.00433 |
| Opus 5.5 | $0.00042 | $0.00173 |
| Sonnet 5.5 | $0.00021 | $0.00087 |
| Haiku 4.5 | $0.00010 | $0.00043 |
Grade A, and why
lua-opinionated-guide 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 1mo 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.
What it actually says
Lua Opinionated Guidelines (Performance Tuning)
A performance overlay on lua-guide. Apply lua-guide for all Lua fundamentals: module pattern, local variables, metatables, coroutines, input validation, error handling, string building, idioms. This skill adds only hot-path tuning: the tunings especially benefit LuaJIT, and the same principles still help vanilla Lua 5.4.
Requirements
- LuaJIT 2.1 (these tunings especially target JIT compilation) or Lua ≥ 5.4 (principles still apply).
Essentials
- Foundation - All Lua fundamentals live in lua-guide; this skill adds hot-path performance tuning on top
- Simple hot loops - Iterate dense arrays with a plain numeric for-loop; don't over-engineer with unrolling or FFI, see references/jit-friendly-tables.md
- Cache lookups - Hoist repeated global/module-table lookups into locals on hot paths, see references/cache-lookups.md
Gotchas
- Apply hot-path tuning only where profiling shows a need: don't over-engineer with FFI arrays or SIMD-style tricks beyond what was asked
Progressive disclosure
- Read references/jit-friendly-tables.md - Load when optimizing hot paths or improving JIT performance
- Read references/cache-lookups.md - Load when reducing table access overhead in performance-critical code
What ships with it
6 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.
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.

lua-opinionated-guide is a skill published in the GitHub repository xonovex/platform (6 stars, last pushed 5d ago), licensed MIT. It adds 104 tokens to every session and 433 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-09-08.
