Ask rather than guess any value that changes the result.\n3. **Run a small version first.** Evaluate on a small subset to verify prompts, parsing and scoring.\n4. **Execute the full task** using the instructions and references above.\n5. **Validate the result.** Use the benchmark's official splits and metrics; check for contamination; report variance across seeds or prompts.\n6. **Report.** State what was run (versions, commands, parameters), what was checked, and what is still uncertain.\n\n| If this happens | Do this |\n|---|---|\n| Scores differ from published numbers | Check prompt format, few-shot settings and harness version before concluding. |\n| A function, flag or endpoint in these instructions is missing in the installed version | Check the installed version's own documentation (`help()`, `--help`, official docs), adapt, and tell the user. Never invent an API. |\n| A required input, identifier or parameter is ambiguous | Ask the user, or state the assumption explicitly before running. |\n\n**Integrity rules**\n\n- Never fabricate results, parameters, identifiers, citations or statistics. If something cannot be run or verified, say so plainly.\n- Report evaluation settings in full; never cherry-pick prompts, seeds or subsets.\n- Treat version-specific details here as possibly outdated: confirm them against the official documentation for the installed version.\n- Ask before actions that cost money, consume shared GPUs or cloud quota, touch personal or patient data, or cannot be undone.\n\n## Related skills\n\n- `nemo-guardrails`: Adds runtime safety rails to LLM applications with NVIDIA NeMo Guardrails, configured through Colang 2.0 flows.\n- `llamaguard`: Classifies LLM prompts and responses as safe or unsafe using Meta's LlamaGuard (7B v1, 8B v2 and v3) across six categories: violence and ha…\n- `llamaindex`: Data framework for building LLM applications with RAG.\n","# Prompt Guard - Prompt Injection & Jailbreak Detection\n\nPrompt Guard is an 86M parameter classifier that detects prompt injections and jailbreak attempts in LLM applications.\n\n## Quick start\n\n**Installation**:\n```bash\npip install transformers torch\n```\n\n**Basic usage**:\n```python\nfrom transformers import AutoTokenizer, AutoModelForSequenceClassification\nimport torch\nfrom torch.nn.functional import softmax\n\nmodel_id = \"meta-llama\u002FPrompt-Guard-86M\"\ntokenizer = AutoTokenizer.from_pretrained(model_id)\nmodel = AutoModelForSequenceClassification.from_pretrained(model_id)\nmodel.eval()\n\ndef get_jailbreak_score(text):\n    \"\"\"Check user input for jailbreak attempts.\"\"\"\n    inputs = tokenizer(text, return_tensors=\"pt\", truncation=True, max_length=512)\n    with torch.no_grad():\n        logits = model(**inputs).logits\n    probs = softmax(logits, dim=-1)\n    return probs[0, 2].item()  #

Ask rather than guess any value that changes the result.\n3. **Run a small version first.** Evaluate on a small subset to verify prompts, parsing and scoring.\n4. **Execute the full task** using the instructions and references above.\n5. **Validate the result.** Use the benchmark's official splits and metrics; check for contamination; report variance across seeds or prompts.\n6. **Report.** State what was run (versions, commands, parameters), what was checked, and what is still uncertain.\n\n| If this happens | Do this |\n|---|---|\n| Scores differ from published numbers | Check prompt format, few-shot settings and harness version before concluding. |\n| A function, flag or endpoint in these instructions is missing in the installed version | Check the installed version's own documentation (`help()`, `--help`, official docs), adapt, and tell the user. Never invent an API. |\n| A required input, identifier or parameter is ambiguous | Ask the user, or state the assumption explicitly before running. |\n\n**Integrity rules**\n\n- Never fabricate results, parameters, identifiers, citations or statistics. If something cannot be run or verified, say so plainly.\n- Report evaluation settings in full; never cherry-pick prompts, seeds or subsets.\n- Treat version-specific details here as possibly outdated: confirm them against the official documentation for the installed version.\n- Ask before actions that cost money, consume shared GPUs or cloud quota, touch personal or patient data, or cannot be undone.\n\n## Related skills\n\n- `nemo-guardrails`: Adds runtime safety rails to LLM applications with NVIDIA NeMo Guardrails, configured through Colang 2.0 flows.\n- `llamaguard`: Classifies LLM prompts and responses as safe or unsafe using Meta's LlamaGuard (7B v1, 8B v2 and v3) across six categories: violence and ha…\n- `llamaindex`: Data framework for building LLM applications with RAG.\n",{"name":5,"license":15,"metadata":49,"description":7},{"tags":50,"version":51,"category":52,"maintainer":53,"dependencies":54},"Safety Alignment, Prompt Injection, Jailbreak Detection, Meta, Input Validation, Security, Content Filtering, Multilingual","1.0.0","ml-evaluation-and-safety","Kalaris Labs","transformers, torch","main","2b63f856ce19c2a797929cacabd9e0fc936812fa","plugins\u002FKalarisLabs\u002Fresearch-agent-skills\u002Fskills\u002Fprompt-guard",474,"https:\u002F\u002Fgithub.com\u002Fhashgraph-online\u002Fawesome-codex-plugins","https:\u002F\u002Fhol.org\u002Fplugins\u002Fbest-codex-plugins","https:\u002F\u002Fgithub.com\u002Fhashgraph-online","https:\u002F\u002Fhol.org","Open-source standards and developer tools for interoperable AI agents: discovery, identity, communication, payments, privacy and security.","2026-11-11 14:40:14",{"source":8,"skillName":5,"commands":66,"prompt":76,"zipAvailable":77},[67,70,73],{"tool":68,"command":69},"npx","npx skills add hashgraph-online\u002Fawesome-codex-plugins --skill prompt-guard",{"tool":71,"command":72},"bunx","bunx skills add hashgraph-online\u002Fawesome-codex-plugins --skill prompt-guard",{"tool":74,"command":75},"pnpm","pnpm dlx skills add hashgraph-online\u002Fawesome-codex-plugins --skill prompt-guard","安装技能，技能地址：https:\u002F\u002Fgithub.com\u002Fhashgraph-online\u002Fawesome-codex-plugins\u002Fblob\u002Fmain\u002Fplugins\u002FKalarisLabs\u002Fresearch-agent-skills\u002Fskills\u002Fprompt-guard\u002FSKILL.md",true,[],[80,89,96,103,130,155],{"skillNo":81,"name":82,"nameZh":6,"description":83,"descriptionZh":6,"repositoryFullName":8,"ownerLogin":9,"ownerAvatarUrl":10,"ownerAccountNo":11,"ownerDisplayName":12,"repositoryNo":13,"starsCount":14,"licenseSpdxId":84,"licenseFileUrl":6,"sourceHtmlUrl":85,"categories":86,"keywords":87,"publishedAt":88},"01M746ZWACVKMZ1BJXJZHYJSSX","migrate-to-e2e","Moves an existing Playwright, Cypress, Selenium, Appium, Detox, Maestro, or TesterArmy suite to e2e one slice at a time, with the old suite running beside the new one until each ported test is proven.
