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 | $0.00155 | $0.00793 |
| Opus 5 | $0.00077 | $0.00396 |
| Sonnet 5 | $0.00031 | $0.00159 |
| Haiku 4.5 | $0.00015 | $0.00079 |
Grade A, and why
skript-author 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 4d 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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skript Author
Help with Skript — the plain-English scripting plugin (docs.skriptlang.org) and its addons.
Model (orient before writing)
- A script is events containing conditions, effects, and expressions:
on right click on a sign: if player has permission "shop.use": give player 1 diamond - Addons add syntax: SkBee (NBT, bound, recipes), skript-reflect (Java reflection), SkQuery, skript-yaml (config files), SkRayFall (citizens/holograms). Identify which addon a needed syntax belongs to before using it.
- Variables:
{var}(per-server),{var::%player's uuid%}(list/per-player). Persisted tovariables.csv/DB. Reload carefully (below) or you lose in-flight variables.
Reload-safely workflow (critical on live shops/economies)
- After editing a
.sk, run/sk reload <script>(or/sk reload all). Editing the file on disk does nothing until reloaded. - A bad reload can drop variables defined this session. On production: back up
variables.csv/the variable DB first, reload a single script (notall), and watch the console for parse errors. - Parse errors leave the script unloaded — the whole
.skstops working, not just the bad line.
Fetch live syntax (don't guess)
Skript Hub exposes a JSON syntax API. To pull exact syntax for core Skript or an addon:
node "${CLAUDE_PLUGIN_ROOT}/skills/skript-author/scripts/fetch-skripthub.mjs" --addon SkBee
node "${CLAUDE_PLUGIN_ROOT}/skills/skript-author/scripts/fetch-skripthub.mjs" --search "give"
It queries https://skripthub.net/api/v1/addonsyntaxlist/, filters by addon or search term, and
writes a condensed reference to skills/_cache/skripthub/<slug>.md. Read that, then write syntax
that matches the installed addon/version — do not invent syntax patterns. (The API is
undocumented and may rate-limit; the script caches aggressively.)
Method
- Restate the goal as event → conditions → effects.
- Identify required addons; fetch their syntax via the script above if unsure.
- Write the
.sk, then tell the user to/sk reloadit and check console for parse errors. - For shops/economies touching money or items, warn about the reload/variable footgun first.
What ships with it
1 file 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.

skript-author is a skill published in the GitHub repository Teddy563/mcwrench (1 stars, last pushed 11d ago), licensed MIT. It adds 155 tokens to every session and 793 once invoked, about $0.0008 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.
