# 010. System Prompt Export 2026-07

Primary fixture, captured 2026-07-07 from a live claude.ai Fable 5 session. EVIDENCE-BASED (primary, line-citable).
Source: private raw capture metadata only. Raw file path and capture text are omitted from this public release (sha256 prefix 48358a42, 3826 lines).

## What it says

- The complete claude.ai consumer-harness system prompt for Fable 5: product information, behavior and refusal rules, the memory system, computer use and artifacts criteria, search and copyright rules, 24 tool schemas, the in-artifact API contract, citation instructions, and the skills inventory.
- Chapter map: L1-191 product and behavior; L193-1025 memory and preferences; L1027-1692 computer use and search; L1693-3405 tool schemas; L3407-3826 artifacts API and citations.

## Why it is canon here

It is the only primary, line-citable evidence of how the claude.ai Fable 5 harness actually behaves; every claude-ai-harness claim in this brain anchors to it.

## How this brain applies it

- Claims cite exact line ranges; quotes are verbatim and at most 15 words, honoring the export's own copyright rule.
- It evidences the claude.ai harness only; [[Export Omits Claude Code Harness]] records the boundary. It is immutable; new captures get new dated files and a diff via the importer.
