session-source-fork

Fine to try.

Use when authoring a rig spec member or `rig expand` payload that needs to start a new managed seat from a prior runtime conversation source — `session_source: { mode: fork, ref: { kind, value } }`. v1 supports `mode: fork` with `ref.kind: native_id` for Claude and Codex. The new seat persists a NEW post-fork token; the parent token is NEVER written onto the new seat. NOT for restoring an existing seat or for artifact-backed mental-model rebuild.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'session-source-fork' ] || [ -L ~/.agents/skills/'session-source-fork' ]; then echo 'A skill folder named session-source-fork already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/mvschwarz/openrig' "$d" && git -C "$d" checkout --quiet 'd9292d5b0464c242a4c8d8da4bda7c42bce0b564' -- 'packages/daemon/specs/agents/shared/skills/core/session-source-fork' && mkdir -p ~/.agents/skills && cp -R "$d"/'packages/daemon/specs/agents/shared/skills/core/session-source-fork' ~/.agents/skills/'session-source-fork' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'session-source-fork' ~/.claude/skills/'session-source-fork' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
