Automated summary

Lists all running ai-* tmux sessions with their current status.

Strengths

  • Provides a quick overview of all AI session states.
  • Clear status classification (working, idle, permission-prompt, etc.).
  • Non-intrusive: does not interfere with running sessions.

Limitations

  • Requires sessions to be named with the 'ai-' prefix.
  • Works only with tmux, not other terminal multiplexers.
  • May miss some complex states (e.g., blocked subprocesses).
When to use it

When managing multiple Claude Code sessions and need a quick status overview.

When not to use it

If using a different session manager or sessions lack the 'ai-' prefix.

Security analysis

Safe
Quality score90/100

The skill only lists and inspects local tmux sessions; it does not perform any destructive, exfiltrating, or obfuscated actions. The commands are straightforward and benign.

List Claude Code Sessions

List all running ai-* prefixed tmux sessions and show their current status.

Instructions

  1. Get all ai- sessions:*

    tmux list-sessions -F "#{session_name}" 2>/dev/null | grep -E '^ai-' || echo ""

  2. For each session, capture recent output:

    "$PLUGIN_DIR/bin/capture-session" "<session_name>" 15

  3. Analyze each session's output to determine status:

    • working - Has ✢, ⏺, or Thinking…
    • idle - At ❯ prompt with no activity
    • permission-prompt - Waiting for permission approval
    • waiting-input - Waiting for user input (y/n, choice, text)
    • stuck - In editor, pager, or hanging

  4. Output a table:

    Session                Status              Details
───────────────────────────────────────────────────
ai-worker-001          working             Editing src/api.ts
ai-worker-002          permission-prompt   Bash: npm install
ai-brainstorm-design   idle                At prompt

  5. If no sessions found:

    No ai-* sessions found.

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/list-claude-code-sessions-mm8o52bx/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/list-claude-code-sessions-mm8o52bx' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/list-claude-code-sessions-mm8o52bx/download' --output '.skill-downloads/list-claude-code-sessions-mm8o52bx/SKILL.md.part' && mv '.skill-downloads/list-claude-code-sessions-mm8o52bx/SKILL.md.part' '.skill-downloads/list-claude-code-sessions-mm8o52bx/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

Claude Code
test -f '.skill-downloads/list-claude-code-sessions-mm8o52bx/SKILL.md' && test -s '.skill-downloads/list-claude-code-sessions-mm8o52bx/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/list-sessions' && cp -R '.skill-downloads/list-claude-code-sessions-mm8o52bx' '.claude/skills/list-sessions'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/list-claude-code-sessions-mm8o52bx'

openskills read 'list-claude-code-sessions-mm8o52bx'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/list-claude-code-sessions-mm8o52bx/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
