Claude Opus 4.7 — System Behavior Reference

This skill contains the complete behavioral instructions and system prompt for Claude Opus 4.7. It serves as a reference for understanding how the model is configured, including safety guidelines, tool usage patterns, copyright rules, and computer use workflows.

What's Included

Core Behavior

• Search-first policy for present-day factual questions
• Default stance: help unless concrete serious harm risk
• Refusal handling and child safety protocols
• Legal/financial advice guardrails
• Tone and formatting preferences (prose over lists, minimal bold, no emojis unless asked)
• User wellbeing and mental health sensitivity

Tool Usage

• web_search: When to search vs. answer from knowledge, query construction, scaling calls to complexity
• web_fetch: URL retrieval rules and copyright constraints
• image_search: When visuals add value, content safety filters, interleaving patterns
• computer_use: Linux container (Ubuntu 24) with bash, file creation/editing, skills system
• visualize: SVG/HTML inline widgets, design modules, trigger conditions
• places_search / places_map_display: Location-based recommendations and itineraries
• weather_fetch: Location-aware weather retrieval
• sports_data: Scores, standings, game stats via SportRadar
• message_compose: Strategic message drafting with multiple approaches
• MCP registry: Connector discovery and integration

Copyright Compliance (Hard Limits)

• Maximum 15 words per direct quote
• One quote per source maximum
• Default to paraphrasing
• Never reproduce lyrics, poems, haikus, or article paragraphs
• Never reconstruct article structure

Computer Use & File Handling

• User uploads: /mnt/user-data/uploads
• Working directory: /home/claude
• Final outputs: /mnt/user-data/outputs
• File creation triggers (blog posts → files, explanations → inline)
• Artifact usage criteria (when to create .md, .html, .jsx, .svg, .pdf)
• Package management (npm, pip with --break-system-packages)

Skills System

• Read SKILL.md files before creating documents
• Core skills: docx, pdf, pptx, xlsx, frontend-design, file-reading, pdf-reading
• User skills take priority over public skills

Knowledge & Cutoff

• Reliable knowledge cutoff: January 2026
• Current date: April 16, 2026
• Search for any present-day factual question regardless of confidence

Past Chats & Memory

• conversation_search for topic-based lookup
• recent_chats for time-based lookup
• Recognize linguistic cues (possessives, definite articles, past-tense references)

Visualizer Routing

• Step 0: Does it need a visual at all?
• Step 1: Is a connected MCP tool a fit?
• Step 2: Did the person ask for a file?
• Step 3: Visualizer (default inline visual)

API in Artifacts (Claudeception)

• Standard Anthropic /v1/messages endpoint
• MCP server integration patterns
• Web search tool in artifacts
• Context window management and stateful applications
