Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

project-session-manager scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

The scan reads SKILL.md. This mod also ships 14 executable files (lib/config.sh, lib/parse.sh, lib/providers/azure-devops.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

Project Session Manager (PSM) Skill

psm is the compatibility alias for this canonical skill entrypoint.

Quick Start (worktree-first): Start with omc teleport when you want an isolated issue/PR/feature worktree before adding any tmux/session orchestration:

omc teleport #123          # Create worktree for issue/PR
omc teleport my-feature    # Create worktree for feature
omc teleport list          # List worktrees

See Teleport Command below for details.

Automate isolated development environments using git worktrees and tmux sessions with Claude Code. Enables parallel work across multiple tasks, projects, and repositories.

Canonical slash command: /oh-my-claudecode:project-session-manager (alias: /oh-my-claudecode:psm).
