Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00015 | $0.00355 |
| Opus 5.5 | $0.00006 | $0.00142 |
| Sonnet 5.5 | $0.00003 | $0.00071 |
| Haiku 4.5 | $0.00002 | $0.00036 |
Grade A, and why
rpg-impact scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 20d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
rpg-impact — Full Impact set, no server required
Run against the current vault (CWD must be the vault root).
If the vault's MCP server is running (the mcp__rpg-vault__impact_set tool is available in this session), call it instead with { name: "$ARGUMENTS" }: it answers from the server's live index in one call, with the same result. Otherwise, run the script:
node --disable-warning=ExperimentalWarning "${CLAUDE_PLUGIN_ROOT}/scripts/impact.mjs" --vault "$(pwd)" "$ARGUMENTS"
(--disable-warning only silences Node's "SQLite is experimental" banner — the in-memory index this command builds — so it doesn't clutter the output.)
Show the items it lists to the user as-is. Each item is a note, Document or
Mirror, with why it's included — relation (a wikilink or a canonical
## Relações line), mention (the name shows up in the prose without a
link), ambiguous-mention (a short or otherwise ambiguous name — "confirmar",
never a block) or mirror (a Foundry journal copy, also never a block) —
and whether it blocks. If it reports the entity as not found, say so and ask
for the correct name — derived names and aliases: both resolve, so a comma
title's short form (e.g. "Corvina" for "Corvina, a Receptadora") and any
alias work too.
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-impact is a command published in the GitHub repository vstrapasson/rpg-marketplace (2 stars, last pushed 20d ago), licensed MIT. It adds 15 tokens to every session and 355 once invoked, about $0.0001 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 2026-09-28.
