Session Saver Claude Code mod: Claude Code session resume notes with /park

Session Saver is a community mod by Hamza Zafar (hamzafer), part of his claude-code-mods collection. It handles the Claude Code session resume problem: you come back to a session and no longer remember where it stood. The mod does three things:

• Names untitled sessions. After your second turn, if the session has no custom title, it asks Haiku for a two-to-four word name such as ship-mods and renames the session through the separate unpause tool, so unpause list shows a name instead of a bare id.
• /park [note] saves where you left off and the next step, plus any note you type.
• Shows the note on resume. A resumed session gets a green ↩ Last time (2h ago): … line above the prompt and an 8-second toast. The line goes away when you type.

The install block above adds the author's marketplace and installs the plugin from it. Automatic naming needs the unpause tool from the author's other repository; everything else works without it. Restart Claude Code or run /reload-plugins afterwards.

The plugin is one function-hooks module, hooks/register.tsx, plus hooks/bands.ts, a shared helper that lets several band mods stack above the prompt. On turn.complete it counts turns and starts naming once. This is from register.tsx:

if ((await $.session.turns()) >= NAME_AFTER_TURNS && !(await $.store.get(`named:${id}`))) {
  await $.store.set(`named:${id}`, true) // one try per session, whatever happens
  void autoname($, id).catch(() => {})
}

autoname runs unpause list --json, leaves the session alone if it already has a custom_title, and otherwise renames it. /park and the last-asked fallback are stored per session id in the plugin's store (park:<id> and last:<id>). On session.start, and on classic.SessionStart with the resume source, the mod loads the note, toasts it and renders it in the AbovePrompt slot. The prompt.submit hook only reads your text; it ignores engine-wrapped prompts such as task notifications and returns the prompt unchanged.

There are no settings. The summary model (haiku) and the number of turns before naming (2) are constants at the top of register.tsx, so changing them means forking the plugin. The line above the prompt follows the band order file at <config dir>/claude-code-mods/bands.json if you use the author's checklist CLI; without that file it simply draws above other mods. The order is read once per session.

We read every file the plugin loads: plugin.json, hooks/hooks.json, hooks/register.tsx, hooks/bands.ts, the types file and the tests. There is no package.json, no bundled or minified code and no binaries. Findings:

• Network: none in the plugin code. The only model traffic is $.model.complete to Haiku, with the conversation excerpts described in the FAQ.
• Processes: $.process.run only for unpause list --json and unpause rename <id> <name>, as argv arrays with a 20-second timeout. The name is lowercased and reduced to a-z0-9- first. unpause is not bundled and we did not audit it.
• File writes: none directly. Notes live in the plugin store ($.store) and Claude Code state atoms. It reads CLAUDE_CONFIG_DIR and HOME, and reads the band order file if it exists. It does not touch settings.json, shell files or LaunchAgents.
• Daemons, secrets, telemetry: none.
• Prompt influence: it injects nothing into prompts or tool results. The /park summary prompt wraps the transcript in tags and asks for JSON only; the reply is parsed and trimmed to 80 and 60 characters before being shown.
• Gating hooks: prompt.submit and classic.SessionStart always call next. validate notes that neither has a .catch.
• License: MIT, with a LICENSE file at the repository root.

claude plugin validate reported no errors and one non-blocking warning (no plugin icon). claude plugin test ran the author's 8 tests on 2.1.307: 8 pass, 0 fail.

We tested commit 5c925b0 on Claude Code 2.1.307. If nothing seems to happen:

• No session name: check that unpause is on your PATH. Naming is tried once per session and failures are silent.
• No note on resume: you need to have typed something or run /park in the earlier session, and the session must be resumed with the same id.
• /park says "no AI summary": the model call was not answered, and the reason is shown in brackets. The fallback "you asked: …" line is saved instead.
• /park command missing: if Claude Code already has a command with that name, registration is refused and the mod starts without it.
