What it does

Session Manager Driver is an agent skill from bobmatnyc/claude-mpm. Drive the trusty-mpm session manager (binary tm) to spawn, observe, command, and decommission durable tmux-backed Claude Code sessions in isolated workspaces. Wraps the tm session CLI / REST API and provides the spawn → observe → answer → stop/resume/decommission loop. Critically, the DRIVER interprets the raw tmux pane using its own inference — it does NOT depend on the daemon's optional LLM (no OpenRouter key required).

Its SKILL.md is about 3.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Model routing and gateways, REST APIs and Git worktrees. It works with tmux and OpenRouter. The repository describes itself as: Claude Multi-Agent Project Manager — multi-channel orchestration, GitHub-first SDK mode, and plugin system for Claude.

When your agent uses it

  • Tasks that involve Model routing and gateways
  • Tasks that involve REST APIs
  • Tasks that involve Git worktrees

Example prompts

  • “/session-manager-driver”

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. pending_decision is non-null in the activity response, or
  2. raw_pane shows an interactive prompt the structured state missed

What it can do on your machine

Read from SKILL.md and the folder at commit 25203d3. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • jq
    • curl
    • git
    • cargo

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Session Manager Driver loads about 3.9k tokens when it runs. Until then it costs about 113 tokens; SKILL.md has 1,408 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~113
When it runs · the whole SKILL.md, loaded when a task matches
~3.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md
