Open-sourced Claude Code prompts reverse-engineered using Claude

A developer has open-sourced a collection of 26 prompts reverse-engineered from Claude Code's source code using Claude itself. The TypeScript source was briefly available as a public npm package before being taken down, during which time the developer studied every prompt in the codebase and used Claude to help rewrite them from scratch.

Prompt categories and structure

The collection contains:

• 1 system prompt covering identity, safety, code style, tool routing, and output rules
• 11 tool prompts for shell, file read/edit/write, grep, glob, web search/fetch, agent launcher, ask user, and plan mode
• 5 agent prompts: general purpose, code explorer, solution architect, verification specialist, and documentation guide
• 4 memory prompts for conversation summarization, session notes, memory extraction, and consolidation
• 1 coordinator prompt for multi-agent orchestration
• 4 utility prompts for session titles, tool summaries, away recaps, and next action suggestions

Notable implementation details

Several specific patterns emerged from the analysis:

• A dedicated verification agent whose entire job is to try to break implementations before reporting them as done
• 6 specific "rationalization patterns" the system watches for in itself, such as "the code looks correct based on my reading" which triggers the response "reading is not verification, run it"
• The memory system compresses conversations into 9 structured sections while preserving every user message
• The coordinator prompt includes the instruction "never delegate understanding" — requiring agents to prove they understood before handing off work

Legal and technical considerations

Every prompt was independently authored in the developer's own words, with automated originality checks confirming no verbatim matches with the original source. The repository includes a full disclaimer covering nominative fair use, non-affiliation with Anthropic, and a DMCA response policy. Legal consultation was obtained before publishing.
