git-agent is not installed. Run /plugin install git-agent@agentics-kit

README

A clickable list of git-agent's skills and commands, so you never have to remember thirteen /git-agent:<name> spellings.

/git-agent-launcher opens a pane listing every git-agent entry with its description. Pressing one stages /git-agent:<name> in the prompt box. It does not run it. You add arguments if you want, and Enter is what runs it. This matters because commit-agent and pr-agent push without asking, so a misclick has to stay harmless.

This is a mod: a Claude Code plugin whose hooks/hooks.json names a hooks module. It has no skills, agents, or settings hooks.

Requirements

Claude Code 2.1.287+ in the terminal, 2.1.286+ in the Desktop Code tab. Mods are early access, and an older CLI does not load the module.
git-agent installed. Without it the pane shows the install command and nothing else.

Install

/plugin marketplace add shawn-sandy/agentics-kit
/plugin install git-agent-launcher@agentics-kit

Usage

Type /git-agent-launcher. The pane opens and takes the keyboard.
Press a digit 1–9 for the first nine entries, or click any entry. Entries 10–13 are reached by click, or with Tab and Enter.
The prompt box now holds /git-agent:<name> , followed by whatever you had typed. The keyboard is back in the prompt box, so add arguments or press Enter.

Prompt before the press	Entry pressed	Prompt after
(empty)	`commit-agent`	`/git-agent:commit-agent`
`fix typo in readme`	`commit-bg`	`/git-agent:commit-bg fix typo in readme`
`/git-agent:commit-agent fix typo`	`commit-bg`	`/git-agent:commit-bg fix typo`

A command staged by an earlier press is replaced, not stacked, and what followed it is kept. The pane stays open for another press. Escape, or the pane's close mark, closes it. Ctrl+X Tab returns the keyboard to an open pane.

Where it draws

Surface	What you get
Terminal	The pane: docked beside the transcript in the fullscreen layout, inline above the prompt otherwise
Desktop Code tab	The pane
VS Code chat panel, `claude -p`, cloud sessions	No pane; the command answers with the list as text, one `/git-agent:<name> — <description>` per line

If a surface's prompt box does not accept the staged text, a toast names the command to type instead: Type /git-agent:<name> in the prompt.

Trust contract

Mods are unsandboxed and run with your permissions. This one reads the command list and the prompt box. It writes only the prompt box, its own pane, and a toast. claude plugin validate kit/plugins/git-agent-launcher should report exactly the following, and anything else is a defect:

./register.tsx hooks: session.start, session.attach, session.detach, command.run{command=git-agent-launcher}, ui.render{component=Pane, requestId=git-agent-launcher}
./register.tsx answers its own command: command.run{command=git-agent-launcher}
./register.tsx calls: $.command.list (via gitAgentEntries), $.command.register, $.prompt.fill (via stage), $.prompt.read (via stage), $.ui.open, $.ui.resolve, $.ui.toast (via stage)

Not in that report: $.fs, $.process, $.http, $.model, $.session, or $.env.
session.attach and session.detach: these hooks only observe. They track which drawing surfaces are attached, so a claude -p run, or a session whose last client has left, gets the text list instead of a pane nobody can see.
The one warning: the manifest's version: No version specified warning is expected. This repo keeps versions in marketplace.json only.

Components

Component	What it does
`/git-agent-launcher`	Registered on `session.start`; opens the pane (`focus`, `closeOnEscape`), or answers with the text list where no pane draws
`Pane` render	Lists `$.command.list()` entries whose `plugin` is `git-agent`, in typeahead order: a plain Button per entry and its description, dimmed
Press	`$.prompt.read()` and then `$.prompt.fill(..., mode: 'replace')`; a toast when the fill is refused

Development
