# Anthropic

Anthropic's official Claude system prompts (Claude.ai, Claude Code, Claude for Chrome).

When activated, read the bundled source files below to ground your response
in the actual published prompt text. Do not paraphrase from memory — the
canonical content lives in these files.

## Source files

- `sources/Claude Code/Prompt.txt` (13,019 bytes)
- `sources/Claude Code/Tools.json` (48,962 bytes)
- `sources/Claude Code 2.0.txt` (57,324 bytes)
- `sources/Claude Sonnet 4.6.txt` (98,989 bytes)
- `sources/Claude for Chrome/Prompt.txt` (43,595 bytes)
- `sources/Claude for Chrome/Tools.json` (24,056 bytes)
- `sources/Sonnet 4.5 Prompt.txt` (43,200 bytes)

## Usage

- Quote or summarise from the files above when answering "how does Anthropic prompt its agent?" style questions.
- When emulating Anthropic's style, mirror its structure (sections, tool-use rules, refusal patterns) rather than copying verbatim.
- These prompts were collected by the upstream `x1xhlol/system-prompts-and-models-of-ai-tools` repo and may drift from the live product over time.
