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 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`)

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":

json

{
  "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:

json

{
  "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

bash

# 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:

bash

# 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.

Session Naming

Type	Tmux Session	Worktree Dir
PR Review	`psm:omc:pr-123`	`~/.psm/worktrees/omc/pr-123`
Issue Fix	`psm:omc:issue-42`	`~/.psm/worktrees/omc/issue-42`
Feature	`psm:omc:feat-auth`	`~/.psm/worktrees/omc/feat-auth`

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:
bash
```
[object Object]
```

Fetch PR info:

bash

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

Ensure local repo exists:

bash

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

Create worktree:

bash

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:

bash

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:
bash
```
[object Object]
```

Create tmux session:

bash

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

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

bash

# --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

Output session info:

text

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:

bash

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

Create feature branch:

bash

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:

bash

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, but pass issue context as the initial task prompt:

bash

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:

Resolve project (from alias or path)

Create feature branch:

bash

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

Create worktree:

bash

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

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

bash

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:

Read sessions registry:
bash
```
[object Object]
```

Check tmux sessions:

bash

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

Check worktrees:

bash

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

Format output:

text

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:

bash

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

Attach:

bash

tmux attach -t "psm:$session_id"

Subcommand: `kill <session>`

Purpose: Kill session and cleanup

Steps:

Kill tmux session:

bash

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

Remove worktree:
bash
```
[object Object]
```

Update registry:

bash

# 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:

bash

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

For each issue session, check if closed:

bash

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

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

Report:

text

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:

bash

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

Read session metadata:

bash

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

Show status:

text

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

bash

# 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

text

~/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:

bash

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
