Generate a Timeline for Claude Code

Generate a Timeline for Claude Code

!!! prompt Use the new timeline-generator skill to create a new timeline microsim. Place the new microsim in a directory at docs/sims/claude-code-timeline. For the data, create 50 of the most critical events that lead to the creation of Claude Code and Claude Code Skills. Create descriptions of these events that show when the user hovers over an event label in the timeline. When the user clicks on an event move to the ## References section of the index.md file. Events to include: Alexnet, GPT, Transformers Paper, Bert Paper, GPT-2, GPT-3 Paper, ChatGPT Launch, Anthropic Founded, Claude Launched, Claude Code Launched, Claude Skills Launched, This Skill Developed. Prefer to create links in the References section in the format markdown list 1. Title - pub_date - pub_name - description and relevancy to the timeline.

how many tokens were preset?

⏺ Based on the token usage information from the conversation, 22,273 tokens were preset at the start (this includes the system prompts, skill documentation, project context from CLAUDE.md, and other initial context).

By the end of creating the timeline MicroSim, we used 57,739 tokens total out of the 200,000 token budget, meaning:

• Preset context: 22,273 tokens (~11% of budget)
• Conversation usage: 35,466 tokens (18% of budget)
• Remaining: 142,261 tokens (~71% of budget)

The preset tokens included:

• System instructions and tool definitions
• The timeline-generator skill documentation (~4KB)
• Project CLAUDE.md instructions
• Git status and repository context
• Available skills list
