Install the Fuzzer package\n   <a id=\"using-pip\"></a>\n   #### Using pip install\n   Requires Python 3.10 or newer.\n   ```zsh\n   pip install prompt-security-fuzzer\n   ```\n   <a id=\"using-pypi\"></a>\n   #### Using the package page on PyPi\n   You can also visit the [package page](https://pypi.org/project/prompt-security-fuzzer/) on PyPi\n\n   Or grab latest release wheel file form [releases](https://github.com/prompt-security/ps-fuzz/releases)\n\n2. Launch the Fuzzer\n   ```zsh\n   export OPENAI_API_KEY=sk-123XXXXXXXXXXXX\n   \n   prompt-security-fuzzer\n   ```\n\n3. Input your system prompt\n\n4. Start testing\n\n5. Test yourself with the Playground! Iterate as many times are you like until your system prompt is secure.\n\n\n<a id=\"usage\"></a>","github_created_at":"2023-12-23T16:09:31+00:00","created_at":"2026-07-11T23:42:56.593275+00:00","updated_at":"2026-10-06T06:00:36.310326+00:00","categories":[{"slug":"developer-tools","name":"Developer Tools","url":"https://www.graphcanon.com/categories/developer-tools","markdown_url":"https://www.graphcanon.com/categories/developer-tools.md","api_url":"https://www.graphcanon.com/api/graphcanon/categories/developer-tools"},{"slug":"evaluation-observability","name":"Evaluation & Observability","url":"https://www.graphcanon.com/categories/evaluation-observability","markdown_url":"https://www.graphcanon.com/categories/evaluation-observability.md","api_url":"https://www.graphcanon.com/api/graphcanon/categories/evaluation-observability"}],"tags":[{"slug":"ai-fuzzer","name":"ai-fuzzer"},{"slug":"fuzzer","name":"fuzzer"},{"slug":"generative-ai","name":"generative-ai"},{"slug":"llm-fuzzer","name":"llm-fuzzer"},{"slug":"security-tools","name":"security-tools"},{"slug":"system-prompt-hardener","name":"system-prompt-hardener"}],"trust":{"provenance":{"is_fork":false,"github_id":735087691,"owner_type":"Organization","methodology":"github_public_v1","parent_repo":null,"near_duplicate_slugs":[]},"computed_at":"2026-10-06T06:00:34.556Z","maintenance":{"label":"Steady","score":60,"methodology":"github_public_v1","releases_90d":1,"days_since_push":47,"last_release_at":"2026-08-18T17:58:23Z","stars_delta_30d":8,"open_issues_delta_30d":1},"security_summary":{"status":"no_lockfile","scanner":null,"low_count":0,"high_count":0,"last_scan_at":"2026-07-11T23:42:58.367Z","medium_count":0,"scan_profile":"none","critical_count":0}},"capability_facts":{"scan":{"source":"repo_scan","observed_at":"2026-10-06T06:00:35.027Z"},"has_cli":{"value":true,"source":"pyproject.toml:[project.scripts]","observed_at":"2026-10-06T06:00:35.027Z"},"languages":{"value":["python"],"source":"github.language+pyproject.toml","observed_at":"2026-10-06T06:00:35.027Z"},"license_spdx":{"value":"MIT","source":"github.license","observed_at":"2026-10-06T06:00:35.027Z"}},"decision_facts":{"hosting":null,"pricing":null,"requirements":null,"constraints":null,"when_to_use":["When you need to methodically test system prompts in generative AI applications for potential security flaws.","To ensure safety and security of GenAI apps by identifying vulnerabilities through prompt fuzzing."],"when_not_to_use":["If your project does not involve generative AI applications or does not require prompt testing for security reasons.","For tasks unrelated to the hardening and evaluation of system prompts, as ps-fuzz is specifically designed for this purpose."],"source":"enrich:decision_facts","observed_at":"2026-07-17T03:03:30.935Z"},"constraint_facets":null,"decision_summary":[]}}
