-The repo manages configuration for two coding agents and a skill library they share. Neither agent binary is installed by chezmoi: `.chezmoidata/packages.yaml` lists no agent CLIs, so install Claude Code and omp yourself. topgrade runs `omp update` as a custom command.
+The repo manages the agent skill library only. Claude Code (`~/.claude`) and omp (`~/.omp`) configs are not in this repo, and no agent CLI is installed by chezmoi. topgrade runs `omp update` as a custom command.

 ## Shell entry points
 
 - `ai` (fish function) opens a `gum choose` picker over `claude`, `opencode`, `codex`, `hermes`, and `fractal`. Picking `claude` runs `claude --dangerously-skip-permissions`; the others run the binary of the same name. See [fish](/shell/fish).
 - <kbd>Ctrl</kbd> <kbd>A</kbd> runs [`omp-session`](/shell/scripts#omp-session) from the fish and zsh prompt: on the default branch it resumes a session written in the last 3 hours, else opens the `omp-sessions` television cable; on any other branch it resumes that branch's newest session or starts a new one. `tv agents` still lists every installed agent CLI ([television](/tools/television#agents)).
-- `launch_omp_livediff_overlay` and `lc-elir` are omp helpers in `~/.local/bin`; see [omp](/ai/omp#shell-integration) and [scripts](/shell/scripts).
+- <kbd>Ctrl</kbd> <kbd>N</kbd> starts a new omp session from the fish and zsh prompt, skipping every resume rule. Inside the `omp-sessions` cable, <kbd>ctrl-n</kbd> does the same instead of resuming the selected session.
+- `launch_omp_livediff_overlay` and `lc-elir` are omp helpers in `~/.local/bin`; see [scripts](/shell/scripts).
