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:

```bash

omc teleport #123 # Create worktree for issue/PR

omc teleport my-feature # Create worktree for feature

omc teleport list # List worktrees

```

See [Teleport Command](#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).

Commands

Project References

Supported formats:

• Alias: omc#123 (requires ~/.psm/projects.json)
• Full: owner/repo#123
• URL: https://github.com/owner/repo/pull/123
• Current: #123 (uses current directory's repo)

Configuration

Project Aliases (~/.psm/projects.json)

{
  "aliases": {
    "omc": {
      "repo": "Yeachan-Heo/oh-my-claudecode",
      "local": "~/Workspace/oh-my-claudecode",
      "default_base": "main"
    }
  },
  "defaults": {
    "worktree_root": "~/.psm/worktrees",
    "cleanup_after_days": 14
  }
}

Providers

PSM supports multiple issue tracking providers:

Jira Configuration

To use Jira, add an alias with jira_project and provider: "jira":

{
  "aliases": {
    "mywork": {
      "jira_project": "MYPROJ",
      "repo": "mycompany/my-project",
      "local": "~/Workspace/my-project",
      "default_base": "develop",
      "provider": "jira"
    }
  }
}

Important: The repo field is still required for cloning the git repository. Jira tracks issues, but you work in a git repo.

For non-GitHub repos, use clone_url instead:

{
  "aliases": {
    "private": {
      "jira_project": "PRIV",
      "clone_url": "[email protected]:team/repo.git",
      "local": "~/Workspace/repo",
      "provider": "jira"
    }
  }
}

Jira Reference Detection

PSM only recognizes PROJ-123 format as Jira when PROJ is explicitly configured as a jira_project in your aliases. This prevents false positives from branch names like FIX-123.

Jira Examples

# Fix a Jira issue (MYPROJ must be configured)
psm fix MYPROJ-123

# Fix using alias (recommended)
psm fix mywork#123

# Feature development (works same as GitHub)
psm feature mywork add-webhooks

# Note: 'psm review' is not supported for Jira (no PR concept)
# Use 'psm fix' for Jira issues

Jira CLI Setup

Install the Jira CLI:

# macOS
brew install ankitpokhrel/jira-cli/jira-cli

# Linux
# See: https://github.com/ankitpokhrel/jira-cli#installation

# Configure (interactive)
jira init

The Jira CLI handles authentication separately from PSM.

Directory Structure

~/.psm/
├── projects.json       # Project aliases
├── sessions.json       # Active session registry
└── worktrees/          # Worktree storage
    └── <project>/
        └── <type>-<id>/

Session Naming

The public session ID (colon form, e.g. omc:pr-123) is the human-facing

identifier stored in sessions.json and used with psm attach/psm kill. tmux

reserves : and . for its session:window.pane target syntax and silently

rewrites them, so the actual tmux session name uses a tmux-safe form where

those characters become _ (issue #3528). PSM translates the public ID to the

tmux-safe name at every tmux boundary; attach directly with the tmux-safe name.

Implementation Protocol

When the user invokes a PSM command, follow this protocol:

Parse Arguments

Parse {{ARGUMENTS}} to determine:

1. Subcommand: review, fix, feature, list, attach, kill, cleanup, status
2. Reference: project#number, URL, or session ID
3. Options: --branch, --base, --no-claude, --no-tmux, etc.

Subcommand: review <ref>

Purpose: Create PR review session

Steps:

1. Resolve reference:

   # Read project aliases
   cat ~/.psm/projects.json 2>/dev/null || echo '{"aliases":{}}'

   # Parse ref format: alias#num, owner/repo#num, or URL
   # Extract: project_alias, repo (owner/repo), pr_number, local_path

1. Fetch PR info:

   gh pr view <pr_number> --repo <repo> --json number,title,author,headRefName,baseRefName,body,files,url

1. Ensure local repo exists:

   # If local path doesn't exist, clone
   if [[ ! -d "$local_path" ]]; then
     git clone "https://github.com/$repo.git" "$local_path"
   fi

1. Create worktree:

   worktree_path="$HOME/.psm/worktrees/$project_alias/pr-$pr_number"

   # Fetch PR branch
   cd "$local_path"
   git fetch origin "pull/$pr_number/head:pr-$pr_number-review"

   # Create worktree
   git worktree add "$worktree_path" "pr-$pr_number-review"

1. Create session metadata:

   cat > "$worktree_path/.psm-session.json" << EOF
   {
     "id": "$project_alias:pr-$pr_number",
     "type": "review",
     "project": "$project_alias",
     "ref": "pr-$pr_number",
     "branch": "<head_branch>",
     "base": "<base_branch>",
     "created_at": "$(date -Iseconds)",
     "tmux_session": "psm_${project_alias}_pr-$pr_number",
     "worktree_path": "$worktree_path",
     "source_repo": "$local_path",
     "github": {
       "pr_number": $pr_number,
       "pr_title": "<title>",
       "pr_author": "<author>",
       "pr_url": "<url>"
     },
     "state": "active"
   }
   EOF

1. Update sessions registry:

   # Add to ~/.psm/sessions.json

1. Create tmux session (tmux-safe name; :/. are translated to _):

   tmux new-session -d -s "psm_${project_alias}_pr-$pr_number" -c "$worktree_path"

1. Launch Claude Code (unless --no-claude):

   # --dangerously-skip-permissions prevents the "Do you trust this directory?" prompt
   # and repeated tool-approval prompts from stalling the session (issue #2508).
   tmux send-keys -t "psm_${project_alias}_pr-$pr_number" "claude --dangerously-skip-permissions" Enter

   # After claude boots (PSM_CLAUDE_STARTUP_DELAY, default 5s), deliver the task.
   # Use -l (literal) so special characters are not misinterpreted by tmux.
   sleep "${PSM_CLAUDE_STARTUP_DELAY:-5}"
   tmux send-keys -t "psm_${project_alias}_pr-$pr_number" -l \
     "Review PR #$pr_number: \"$pr_title\" by @$pr_author ($head_branch → $base_branch). URL: $pr_url." Enter

1. Output session info:

   Session ready!

     ID: omc:pr-123
     Worktree: ~/.psm/worktrees/omc/pr-123
     Tmux: psm_omc_pr-123

   To attach: tmux attach -t psm_omc_pr-123   (or: psm attach omc:pr-123)

Subcommand: fix <ref>

Purpose: Create issue fix session

Steps:

1. Resolve reference (same as review)

1. Fetch issue info:

   gh issue view <issue_number> --repo <repo> --json number,title,body,labels,url

1. Create feature branch:

   cd "$local_path"
   git fetch origin main
   branch_name="fix/$issue_number-$(echo "$title" | tr ' ' '-' | tr '[:upper:]' '[:lower:]' | head -c 30)"
   git checkout -b "$branch_name" origin/main

1. Create worktree:

   worktree_path="$HOME/.psm/worktrees/$project_alias/issue-$issue_number"
   git worktree add "$worktree_path" "$branch_name"

1. Create session metadata (similar to review, type="fix")

1. Update registry, create tmux, launch claude:

Same as review, but pass issue context as the initial task prompt:

   tmux send-keys -t "psm_${project_alias}_issue-$issue_number" "claude --dangerously-skip-permissions" Enter
   # After claude boots, deliver the task (see PSM_CLAUDE_STARTUP_DELAY):
   tmux send-keys -t "psm_${project_alias}_issue-$issue_number" -l \
     "Fix issue #$issue_number: \"$issue_title\". URL: $issue_url. Branch: $branch_name." Enter

Subcommand: feature <project> <name>

Purpose: Start feature development

Steps:

1. Resolve project (from alias or path)

1. Create feature branch:

   cd "$local_path"
   git fetch origin main
   branch_name="feature/$feature_name"
   git checkout -b "$branch_name" origin/main

1. Create worktree:

   worktree_path="$HOME/.psm/worktrees/$project_alias/feat-$feature_name"
   git worktree add "$worktree_path" "$branch_name"

1. Create session, tmux, launch claude with feature context as initial prompt:

   tmux send-keys -t "psm_${project_alias}_feat-$feature_name" "claude --dangerously-skip-permissions" Enter
   tmux send-keys -t "psm_${project_alias}_feat-$feature_name" -l \
     "Implement feature \"$feature_name\" for project $project. Branch: $branch_name." Enter

Subcommand: list [project]

Purpose: List active sessions

Steps:

1. Read sessions registry:

   cat ~/.psm/sessions.json 2>/dev/null || echo '{"sessions":{}}'

1. Check tmux sessions:

   tmux list-sessions -F "#{session_name}" 2>/dev/null | grep "^psm_"

1. Check worktrees:

   ls -la ~/.psm/worktrees/*/ 2>/dev/null

1. Format output:

   Active PSM Sessions:

   ID                 | Type    | Status   | Worktree
   -------------------|---------|----------|---------------------------
   omc:pr-123        | review  | active   | ~/.psm/worktrees/omc/pr-123
   omc:issue-42      | fix     | detached | ~/.psm/worktrees/omc/issue-42

Subcommand: attach <session>

Purpose: Attach to existing session

Steps:

1. Parse session ID: project:type-number

1. Verify session exists:

   tmux has-session -t "psm_${session_id//[.:]/_}" 2>/dev/null   # translate public id to tmux-safe name

1. Attach:

   tmux attach -t "psm_${session_id//[.:]/_}"

Subcommand: kill <session>

Purpose: Kill session and cleanup

Steps:

1. Kill tmux session:

   tmux kill-session -t "psm_${session_id//[.:]/_}" 2>/dev/null

1. Remove worktree:

   worktree_path=$(jq -r ".sessions[\"$session_id\"].worktree" ~/.psm/sessions.json)
   source_repo=$(jq -r ".sessions[\"$session_id\"].source_repo" ~/.psm/sessions.json)

   cd "$source_repo"
   git worktree remove "$worktree_path" --force

1. Update registry:

   # Remove from sessions.json

Subcommand: cleanup

Purpose: Clean up merged PRs and closed issues

Steps:

1. Read all sessions

1. For each PR session, check if merged:

   gh pr view <pr_number> --repo <repo> --json merged,state

1. For each issue session, check if closed:

   gh issue view <issue_number> --repo <repo> --json closed,state

1. Clean up merged/closed sessions:

• Kill tmux session
• Remove worktree
• Update registry

1. Report:

   Cleanup complete:
     Removed: omc:pr-123 (merged)
     Removed: omc:issue-42 (closed)
     Kept: omc:feat-auth (active)

Subcommand: status

Purpose: Show current session info

Steps:

1. Detect current session from tmux or cwd:

   tmux display-message -p "#{session_name}" 2>/dev/null
   # or check if cwd is inside a worktree

1. Read session metadata:

   cat .psm-session.json 2>/dev/null

1. Show status:

   Current Session: omc:pr-123
   Type: review
   PR: #123 - Add webhook support
   Branch: feature/webhooks
   Created: 2 hours ago

Error Handling

Teleport Command

The omc teleport command provides a lightweight alternative to full PSM sessions. It creates git worktrees without tmux session management — ideal for quick, isolated development.

Usage

# Create worktree for an issue or PR
omc teleport #123
omc teleport owner/repo#123
omc teleport https://github.com/owner/repo/issues/42

# Create worktree for a feature
omc teleport my-feature

# List existing worktrees
omc teleport list

# Remove a worktree
omc teleport remove issue/my-repo-123
omc teleport remove --force feat/my-repo-my-feature

Options

Worktree Layout

~/Workspace/omc-worktrees/
├── issue/
│   └── my-repo-123/        # Issue worktrees
├── pr/
│   └── my-repo-456/        # PR review worktrees
└── feat/
    └── my-repo-my-feature/ # Feature worktrees

PSM vs Teleport

Use PSM for full managed sessions. Use teleport for quick worktree creation.

Requirements

Required:

• git - Version control (with worktree support v2.5+)
• jq - JSON parsing
• tmux - Session management (optional, but recommended)

Optional (per provider):

• gh - GitHub CLI (for GitHub workflows)
• jira - Jira CLI (for Jira workflows)

Initialization

On first run, create default config:

mkdir -p ~/.psm/worktrees ~/.psm/logs

# Create default projects.json if not exists
if [[ ! -f ~/.psm/projects.json ]]; then
  cat > ~/.psm/projects.json << 'EOF'
{
  "aliases": {
    "omc": {
      "repo": "Yeachan-Heo/oh-my-claudecode",
      "local": "~/Workspace/oh-my-claudecode",
      "default_base": "main"
    }
  },
  "defaults": {
    "worktree_root": "~/.psm/worktrees",
    "cleanup_after_days": 14,
    "auto_cleanup_merged": true
  }
}
EOF
fi

# Create sessions.json if not exists
if [[ ! -f ~/.psm/sessions.json ]]; then
  echo '{"version":1,"sessions":{},"stats":{"total_created":0,"total_cleaned":0}}' > ~/.psm/sessions.json
fi
