 ## Development Guidelines
 
+### Recommended Development Setup
+
+**Development via Podman (Recommended)**: This repository is designed to be developed inside a Podman container for consistency and reproducibility. See README.md for complete container setup instructions.
+
+- Run `podman compose up --build` to start development
+- Run commands in the container with `podman compose exec app <command>`
+- This keeps your host environment clean and ensures reproducible builds
+
 ### Commands
+
+#### Local Development (with Podman - Recommended)
+- `podman compose up --build`: Start development container with auto-rebuild
+- `podman compose up -d`: Start development container in background
+- `podman compose exec app npm run dev`: Start dev server inside container
+- `podman compose exec app npm run build`: Build inside container
+
+#### Direct Commands (without Podman)
 - `npm install`: Install dependencies
 - `npm run dev`: Start local development server at `localhost:4321`
 - `npm run build`: Build production site to `./dist/`

----
-name: commit-message-generator
-description: Generate appropriate commit messages based on Git diffs
----
-
-## Prerequisites
-- This Skill retrieves Git diffs and suggests meaningful commit messages
-- Message format should follow Conventional Commits
-- Commit messages should have a one-line Conventional Commits header, an optional blank second line, and from the third line onward include a bulleted list summarizing the changes
-- Commit messages should be in English
-- **Never perform Git commit or Git push**
-
-## Steps
-1. Run `git status` to check modified files
-2. Retrieve diffs with `git diff` or `git diff --cached`
-3. Analyze the diff content and determine if changes should be split into multiple commits
-4. For each logical group of changes:
-   - List the target files
-   - Generate a message in English compliant with Conventional Commits
-   - Suggest the command: `git add <files> && git commit -m "<message>"`
-5. If changes are extensive and should be split, provide:
-   - Rationale for the split
-   - Multiple commit suggestions with their respective target files and messages
-
-## Commit Splitting Guidelines
-- Split commits when changes span multiple logical concerns (e.g., feature + refactoring)
-- Group related files that serve the same purpose
-- Keep each commit focused on a single, atomic change
-
-## Notes
-- **This Skill must never execute `git commit` or `git push`**
-- Only suggest commands; execution is entirely at user's discretion
-- Users must explicitly perform commits and pushes themselves

+title: 'How to Select Sessions When Starting the agent-shell ACP Client Running on Emacs'
+pubDate: 2026-03-01
+author: 'Nakahara Daisuke'
+tags: ["Emacs"]
+---
+
+I recently returned to Emacs, motivated by CLI-type AI tools like [GitHub Copilot CLI](https://github.com/github/copilot-cli).
+
+Copilot CLI supports ACP (Agentic Communication Protocol), which enables communication between AI agents and editors ([GitHub official documentation](https://docs.github.com/en/copilot/reference/acp-server)).
+And [agent-shell](https://github.com/xenodium/agent-shell) is an ACP client that runs on Emacs.
+
+agent-shell can be started with `M-x agent-shell`.
+By default, starting agent-shell creates a new session. However, with the following configuration change, you can choose to create a new session or select from past sessions when starting. I'll introduce this configuration.
+
+## Prerequisites
+
+```shellsession
+$ emacs --version
+GNU Emacs 30.2
+Development version 636f166cfc86 on HEAD branch; build date 2025-12-14.
+Copyright (C) 2025 Free Software Foundation, Inc.
+GNU Emacs comes with ABSOLUTELY NO WARRANTY.
+You may redistribute copies of GNU Emacs
+under the terms of the GNU General Public License.
+For more information about these matters, see the file named COPYING.
+```
+
+This article assumes the use of Copilot CLI.
+
+```shellsession
+$ copilot --version
+GitHub Copilot CLI 0.0.420.
+Run 'copilot update' to check for updates.
+```
+
+After starting Emacs, the result of running `M-x agent-shell-version` is as follows:
+
+```
+agent-shell v0.43.1
+```
+
+## Method
+
+Set the value of `agent-shell-session-strategy` to `prompt`.
+Here is an example configuration in `init.el`:
+
+```emacs-lisp
+(use-package agent-shell
+  :custom
+  (agent-shell-session-strategy 'prompt)
+  :ensure t)
+```
+
+With this configuration, you can create a new session or select from history in the minibuffer. Selecting a new session behaves the same as the default behavior, but selecting a past session allows you to resume work in that session's context. This enables you to efficiently manage multiple different projects and tasks.
