system_prompts_leaks
A community-maintained archive documenting the leaked and extracted system prompts of major commercial AI chatbots and coding agents — Claude, ChatGPT, Gemini, Grok, Perplexity, Copilot and others — organized by vendor, model version, tool, and persona, often with diffs between releases.

npm install system_prompts_leaksOur analysis
A curated, frequently-updated documentation repository that collects the (mostly extracted/leaked) system prompts and tool definitions of mainstream AI products, grouped by vendor and model, including official published prompts, raw versions, persona variants, and version-to-version diffs.
When to use system_prompts_leaks
Use it as a reference when studying how production LLMs are actually instructed — for prompt-engineering inspiration, understanding model guardrails and tool-calling conventions, comparing how vendors differ, or tracking how a model's behavior shifts across releases via the diffs.
When not to
It is not a library or framework you import; if you need executable prompt-management tooling, a prompt-testing harness, or an SDK to build agents, use those tools instead. The contents are also unverified and unofficial, so don't treat them as authoritative ground truth.
Strengths
- Extremely broad coverage across nearly every major vendor and model generation
- Well-organized by vendor/model/tool/persona with collapsible historical archives
- Includes diffs between model versions, which is genuinely useful for tracking behavioral drift
- Very active and high-visibility, with frequent updates as new models ship
Trade-offs
- Prompts are extracted/leaked and unverified — accuracy and completeness can't be guaranteed
- Static markdown documentation only; no tooling, API, or automation
- Legally and ethically gray; reproduces proprietary vendor content
- Inherently lags and goes stale as vendors silently change prompts
- The 'JavaScript' language tag is incidental — this is essentially a content repo
Maturity
Mature as a reference resource by virtue of its large following and steady update cadence, but it is a documentation collection rather than software, so 'production-readiness' doesn't really apply — treat entries as informational and potentially outdated.
