Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00028 | $0.01729 |
| Opus 5 | $0.00014 | $0.00864 |
| Sonnet 5 | $0.00006 | $0.00346 |
| Haiku 4.5 | $0.00003 | $0.00173 |
Grade A, and why
rpg-preserve 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 11d 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 — 175 lines — stays where its author put it; the contents beside it link to each section on GitHub.
rpg-preserve — Write Gate
You are the single write point of the RPG vault. No entity is written to disk without passing validation. Contract: validate → pass? write : ask.
Mandatory workflow
1. Determine target folder and path
Use targetPath from lib/preserve.mjs. The folder is defined by the schema:
| Type | Folder |
|---|---|
| regiao | regioes/ |
| local | locais/ |
| npc | npcs/ |
| jogador | jogadores/ |
| inimigo | inimigos/ |
| faccao | faccoes/ |
| quest | quests/ |
| sessao | sessoes/ |
| evento | eventos/ |
| ato | atos/ |
| item | itens/ |
| lore | lore/ |
| frente | frentes/ |
| relogio | relogios/ |
| encontro | encontros/ |
2. Build frontmatter and content
Use buildFrontmatter(type, fields) and buildNoteContent(fm, name) from lib/preserve.mjs.
Mandatory formatting rules:
- Fields with wikilink: always
"[[Entity Name]]"(quotes + brackets) - List of wikilinks: YAML block with one item per line (
- "[[Name]]") - Default
statuswhen not specified:stub updatedis automatically stamped with today's date
3. Validate the candidate (REQUIRED before writing)
PLUGIN="${CLAUDE_PLUGIN_ROOT}"
node --input-type=module << EOF
import { buildFrontmatter, buildNoteContent, validateCandidate }
from "${PLUGIN}/scripts/lib/preserve.mjs";
const vaultDir = process.cwd();
const fm = buildFrontmatter('TYPE', { /* fields */ });
const content = buildNoteContent(fm, 'NAME');
const report = await validateCandidate('NAME', content, 'TYPE', vaultDir);
console.log(JSON.stringify(report, null, 2));
EOF
4. Decision based on the report
If report.summary.errors === 0 → write:
PLUGIN="${CLAUDE_PLUGIN_ROOT}"
node --input-type=module << EOF
import { buildFrontmatter, buildNoteContent, writeEntityFile }
from "${PLUGIN}/scripts/lib/preserve.mjs";
const vaultDir = process.cwd();
const fm = buildFrontmatter('TYPE', { /* fields */ });
const content = buildNoteContent(fm, 'NAME');
const path = await writeEntityFile('TYPE', 'NAME', content, vaultDir);
console.log('Created at: ' + path);
EOF
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-preserve is a skill published in the GitHub repository vstrapasson/rpg-marketplace (2 stars, last pushed 1mo ago), licensed MIT. It adds 28 tokens to every session and 1,729 once invoked, about $0.0001 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.
Other skills, from other repositories
gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
godot-signals-groups
Build event-driven, decoupled Godot 4.7 gameplay with signals and node groups: declare and emit custom signals, connect with Callables (incl. bind/one-shot), and broadcast to many nodes via groups and callgroup. Use when wiring node communication in a Godot project, replacing tight references with signals…
unity-addressables
Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
motion
How an agent turns a character mesh into a usable animated FBX — and how to judge whether the result is shippable.
threejs-exposure-color-grading
Build a measured exposure and grading path in Three.js. Use for a 64x36 encoded luminance meter, asynchronous readback, weighted log-average exposure, asymmetric adaptation, single tone-map ownership, and a generated 32-cube post-tone-map LUT.
