Show live Claude Code sessions as a process tree, grouped by shared ancestor chain up to launchd. Covers both CLI sessions and Claude Desktop agent mode. Use this skill when asked about the process tree, ancestor lineage, which terminal or tmux window a Claude session is running in, or what's currently running. Trigger phrases: "process tree", "what's running", "lineage", "ancestor chain", "which terminal is my claude in", "tmux tree", "claude process tree", "session lineage". macOS-only: on other platforms the command prints "unsupported" and exits 0.

omnisess ps
Show live Claude Code sessions as a process tree with ancestor lineage.
Usage
omnisess ps
JSON output (machine-readable, includes full ancestor chain with command args):
omnisess ps --json
Instructions
- Check that the
omnisessbinary is available:
if ! command -v omnisess &>/dev/null; then
echo "omnisess not found. Install it with:"
echo " go install github.com/psacc/omnisess@latest"
exit 1
fi
- Run the command:
omnisess ps "$@"
Notes
- macOS-only. On other platforms the command prints
omnisess ps: unsupported on this platform (macOS only)and exits 0. - Detects CLI Claude sessions (launched from a terminal, tmux, etc.) and Claude Desktop agent-mode sessions.
- Tree is rooted at shared ancestors (typically
/sbin/launchdandtmux) so you can see which terminal, tmux pane, or desktop app hosts each session.

Classify agent skills by usage tier (Keep / Borderline / Archive / Unknown) using Claude Code session JSONL transcripts as the signal source. Read-only — never modifies skills, sessions, or any file on disk. Use this skill when asked to audit skills, find unused skills, classify skills, check which skills get used, produce a skill usage report, or prune skills. Trigger phrases: "audit skills", "find unused skills", "classify skills", "which skills do I use", "skill usage report", "prune skills", "what skills are unused", "skills I can remove", "trim my skill list". Output is a recommendation (Keep / Borderline / Archive) — acting on it is always a manual step.
