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).

Commands

Command	Description	Example
`review <ref>`	PR review session	`/psm review omc#123`
`fix <ref>`	Issue fix session	`/psm fix omc#42`
`feature <proj> <name>`	Feature development	`/psm feature omc add-webhooks`
`list [project]`	List active sessions	`/psm list`
`attach <session>`	Attach to session	`/psm attach omc:pr-123`
`kill <session>`	Kill session	`/psm kill omc:pr-123`
`cleanup`	Clean merged/closed	`/psm cleanup`
`status`	Current session info	`/psm status`

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:

Provider	CLI Required	Reference Formats	Commands
GitHub (default)	`gh`	`owner/repo#123`, `alias#123`, GitHub URLs	review, fix, feature
Jira	`jira`	`PROJ-123` (if PROJ configured), `alias#123`	fix, feature

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": "git@gitlab.internal: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.

Implementation Protocol

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

Parse Arguments

Parse {{ARGUMENTS}} to determine:

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

Subcommand: `review <ref>`

Purpose: Create PR review session

Steps:

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

Fetch PR info:

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

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

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"

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

Update sessions registry:
```
# Add to ~/.psm/sessions.json
```

Create tmux session:

tmux new-session -d -s "psm:$project_alias:pr-$pr_number" -c "$worktree_path"

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

tmux send-keys -t "psm:$project_alias:pr-$pr_number" "claude" Enter

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

Subcommand: `fix <ref>`

Purpose: Create issue fix session

Steps:

Resolve reference (same as review)

Fetch issue info:

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

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

Create worktree:

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

Create session metadata (similar to review, type="fix")
Update registry, create tmux, launch claude (same as review)

Subcommand: `feature <project> <name>`

Purpose: Start feature development

Steps:

Resolve project (from alias or path)

Create feature branch:

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

Create worktree:

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

Create session, tmux, launch claude (same pattern)

Subcommand: `list [project]`

Purpose: List active sessions

Steps:

Read sessions registry:

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

Check tmux sessions:

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

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

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:

Parse session ID: project:type-number

Verify session exists:

tmux has-session -t "psm:$session_id" 2>/dev/null

Attach:
```
tmux attach -t "psm:$session_id"
```

Subcommand: `kill <session>`

Purpose: Kill session and cleanup

Steps:

Kill tmux session:

tmux kill-session -t "psm:$session_id" 2>/dev/null

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

Update registry:
```
# Remove from sessions.json
```

Subcommand: `cleanup`

Purpose: Clean up merged PRs and closed issues

Steps:

Read all sessions

For each PR session, check if merged:

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

For each issue session, check if closed:

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

Clean up merged/closed sessions:
- Kill tmux session
- Remove worktree
- Update registry

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:

Detect current session from tmux or cwd:

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

Read session metadata:
```
cat .psm-session.json 2>/dev/null
```

Show status:

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

Error Handling

Error	Resolution
Worktree exists	Offer: attach, recreate, or abort
PR not found	Verify URL/number, check permissions
No tmux	Warn and skip session creation
No gh CLI	Error with install instructions

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

Flag	Description	Default
`--worktree`	Create worktree (default, kept for compatibility)	`true`
`--path <path>`	Custom worktree root directory	`~/Workspace/omc-worktrees/`
`--base <branch>`	Base branch to create from	`main`
`--json`	Output as JSON	`false`

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

Feature	PSM	Teleport
Git worktree	Yes	Yes
Tmux session	Yes	No
Claude Code launch	Yes	No
Session registry	Yes	No
Auto-cleanup	Yes	No
Project aliases	Yes	No (uses current repo)

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
