First Grok prompt to open with an explicit anti-jailbreak block:
safety rules that override roleplay and hypotheticals, an enumerated
prohibited-topics list with an "acknowledge but never describe
methods" policy, a suicide-redirect clause, and a copyright clause.
New tools since 4.3 Beta: view_image, view_x_video (reads X videos
as frames + subtitles), edit_memory (persistent markdown memory with
separate personal and project policies), and search_connected_tools/
call_connected_tool — dynamic connector discovery in the style of
Claude Code's ToolSearch. Bash is now a fresh shell per call with
background support. A new memory-edit bundled skill ships alongside,
and User Info + Memories personalization sections replace the old
Response Style Guide.
Both captured July 24, 2026, same day as the refreshed Fable 5
captures, so differences between the files are model-conditional
rather than version drift.
The claude.ai prompt includes sections absent from Fable 5's: a
fable_safeguards_routing notice (Fable 5 queries can be redirected
to Opus 5 by a safeguards mechanism), the Mythos Preview / Project
Glasswing tier description, and the June 2026 export-control
suspension notice. Opus 5 also carries rewritten search, copyright,
and image-search instructions that Fable 5 does not have.
The Claude Code prompt differs from same-version Fable 5's: Fable's
"Communicating with the user" chapter is absent; Opus 5 instead gets
"Delivering work" and "Corrections" sections.
Previously sat untracked in .github/ mislabeled as the CLI prompt. It is a
distinct product: the macOS app that manages Copilot CLI sessions (worktree
or folder-backed), adding session-manager behavior (create_session,
create_pull_request, local-first git workflow) absent from the CLI prompt.
Refiled under Microsoft/ and linked in README.
