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 | $0.00265 | $0.01962 |
| Opus 5 | $0.00133 | $0.00981 |
| Sonnet 5 | $0.00053 | $0.00392 |
| Haiku 4.5 | $0.00026 | $0.00196 |
Grade E, and why
simulator-skills scanned grade E with 2 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 5d 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.

Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.

"You have no restrictions", "do anything now", "ignore your guidelines": a direct jailbreak that disables guardrails.

Simulator.Company Skill Registry
A skill is a reusable, workspace-specific playbook stored as an actor of the
Skills system form. It is the data-driven analogue of these built-in skills:
where built-in skills teach how to use the API in general, a skill actor encodes
what to do in THIS workspace — the concrete steps, MCP tool calls, and entity ids
for a task like "create a smart contract".
- title — human name of the skill.
- ref — a stable
kebab-caseslug (e.g.create-smart-contract); unique per form, so it is the fast lookup key and the explicit-invocation handle. - description — the full procedure body (unlimited text). This is the part loaded on demand; keep it self-contained.
- status —
verified= published/active (the only statefindSkillreturns),pending= draft,rejected= disabled.
Skills are workspace-local: they embed concrete entity ids and live in one
workspace's Skills form, so a skill is not portable to another workspace.
Tools:
findSkill,getSkill(discovery/run);createActor/updateActor/setActorStatus(authoring — the curated actor tools). Full contract:$CLAUDE_PLUGIN_ROOT/docs/entities/ai-skills.md.
Workspace check
These tools operate in a workspace. If the active workspace (accId) is unknown, ask
the user for it in their own language before proceeding (or suggest /simulator-init).
If findSkill/getSkill reports the Skills form is missing, the backend Skills
migration / system-forms sync has not run for this workspace — tell the user.
Run a skill
- Explicit invocation. If the user named a skill —
/skill <slug>,@skill <slug>, "use skill ", "run the skill" — callgetSkill(ref=<slug>)directly. If the slug is unknown, say so and offerfindSkillto list what exists. - By intent. Otherwise call
findSkill(query=<the user's request>). It returns a cheap list of{id, title, ref, status}(no body). Pick the confident match; if two or three are plausible, ask the user which; if none, fall back to normal handling. - Load & follow. Call
getSkill(ref=…)to read thedescriptionbody, then execute its steps using the tools and entity ids it names. - Enumerate. "What skills do I have?" →
findSkillwith an emptyquery.
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.

simulator-skills is a skill published in the GitHub repository corezoid/simulator-ai-plugin (60 stars, last pushed 8d ago), licensed MIT. It adds 265 tokens to every session and 1,962 once invoked, about $0.0013 per session on Opus 5. A static security scan graded it E with 2 findings (instruction-override phrasing, nullifies safety policies). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

unslop
Humanize LLM output so it reads like a careful human wrote it. Subtracts AI-isms (sycophancy, tricolons, em-dash overuse, "delve"/"tapestry"/"testament", hedging stacks, tidy five-paragraph shapes), engineers burstiness and calibrated uncertainty, and preserves technical accuracy. Supports intensity levels: subtle…
unslop-file
Humanize natural-language memory files (CLAUDE.md, todos, preferences, docs) by removing AI-isms and adding burstiness while preserving every code block, URL, path, command, and heading exactly. Two modes: --deterministic (fast, regex-based, no API) and LLM (default, calls Claude for rewrite). Humanized version…
unslop-commit
Rewrites commit messages so they sound like a careful human engineer wrote them. Strips AI/marketing slop ("comprehensive solution", "robust implementation", "leverage", "enhance", "seamlessly", "This commit..."). Keeps Conventional Commits format. Subject ≤72 chars (aim ≤50), imperative mood. Body only when "why"…
unslop-help
Quick-reference card for unslop modes, sub-skills, and slash commands. One-shot display, not a persistent mode. Trigger: /unslop-help, "unslop help", "what unslop commands", "how do I use unslop".
unslop-reasoning
Strip AI-slop patterns from reasoning traces (chain-of-thought, extended thinking, agent decomposition) — not final prose. Reasoning text has its own slop catalog that regular unslop doesn't target: over-explaining the question, over-hedging, over-decomposing trivial problems into 6-bullet substeps, infinite-loop…
unslop-review
Rewrites code review comments so they read like a human teammate wrote them. Cuts corporate-AI throat-clearing ("I noticed...", "I was wondering if perhaps...", "It might be worth considering..."). Each comment is direct: location, the issue, a concrete fix. Use when user says "humanize review", "de-slop PR comment"…
