simulator-reactions

simulator-reactions is a skill for Claude Code, Codex from corezoid/simulator-ai-plugin. It costs 174 tokens per session (2,374 once invoked), scanned A, original, MIT.

A specialist for reactions attached to Simulator.Company actors, including comments, events, approvals, ratings, and threaded replies. It explains how to identify the parent actor and the individual reaction.

In plain words
What is it for?
Use it to create, read, reply to, update, delete, pin, or mark reactions as read, and to retrieve reaction statistics.
Why use it?
It helps avoid confusing the actor that owns a discussion with the specific reaction being changed, read, pinned, or deleted.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

simulator-reactions 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 — 179 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Curated tool names (v2 server): createReaction, updateReaction, deleteReaction, getReactions, getReactionsStats, markReactionsRead, getPinnedReactions, togglePinnedReaction. Call them by these exact names.

Simulator.Company Reactions Specialist

Reactions are the comments / events / approvals / ratings that live under an actor. They are themselves actors, organised as a hierarchical (threaded) tree, so a reaction can reply to another reaction.

Relationship to the other skills

  • simulator-actors — the actor's own data fields (a reaction is about an actor, not its data).
  • simulator-attachments — files attached to a reaction or actor (a reaction can carry attachments).
  • simulator-graph — graph structure (links/layers), unrelated to reactions.

The one rule that trips everyone up: actorId vs reactionId

Every reaction path is addressed by the parent (root) actor, while the reaction's own id travels separately:

  • actorId (path) = the parent actor whose reaction tree you are working in.
  • reactionId (body, on update/delete/pin) = the specific reaction to act on.
  • parentId (on create) = the reaction you are replying to (omit for a top-level comment).

The tools expose these as distinct arguments, so you never collide the two.

Workspace context

Reactions are addressed by actorId (a UUID), so no accId is needed. Make sure you have the target actor's UUID (use simulator-actors / searchActors to find it) before commenting.


Comment on an actor

createReaction(
  type="comment",                 # everyday note; other types: view, rating, sign, ds, done, reject, freeze; ai = agent reply (see below)
  actorId="<parent actor UUID>",
  description="Looks good to me",  # the comment text
  notify=true)                     # default true; set false to post quietly

Reply in a thread — pass the parent reaction's id as parentId:

createReaction(type="comment", actorId="<parent actor UUID>",
  description="Agreed", parentId="<reaction UUID being replied to>")

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.
