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 | $0.00020 | $0.00438 |
| Opus 5.5 | $0.00008 | $0.00175 |
| Sonnet 5.5 | $0.00004 | $0.00088 |
| Haiku 4.5 | $0.00002 | $0.00044 |
Grade A, and why
rpg-impact-ack scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 20d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
rpg-impact-ack — Dismiss one Impact item for this turn
Run against the current vault (CWD must be the vault root). <nota> is the
item's path exactly as the Impact set printed it (e.g. Prep de Sessão.md
or quests/O Resgate.md), with its .md/.html extension; <motivo> is
a short reason, everything after the path.
If the vault's MCP server is running (the mcp__rpg-vault__impact_ack tool is available in this session), call it instead with { nota, motivo }: it answers from the server's live index in one call, with the same result. Otherwise, run the script:
node "${CLAUDE_PLUGIN_ROOT}/scripts/impact-ack.mjs" --vault "$(pwd)" "$ARGUMENTS"
The whole argument line arrives as one string, so the script splits it
right after the note's extension: Prep de Sessão.md nada a mudar becomes
the note Prep de Sessão.md and the reason nada a mudar. Passing the two
as separate quoted arguments ("<nota>" "<motivo>") works too.
This is the local counterpart of impact_ack(nota, motivo) (spec): it
records the dismissal for the Stop hook (hooks/impact-stop-check.mjs),
which treats that item as handled — but only for the rest of this turn.
The same item in a future turn's Impact set is checked again from scratch,
so don't reach for this as a way to permanently silence an item; update the
note instead, or use it only when the item genuinely needs no change.
If impactGate is block, the Stop hook's message already names each
unhandled item and this exact command to dismiss it — use that instead of
guessing the note's path.
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-ack is a command published in the GitHub repository vstrapasson/rpg-marketplace (2 stars, last pushed 20d ago), licensed MIT. It adds 20 tokens to every session and 438 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.
