# Project Session Manager

Project Session Manager automates isolated development environments using git worktrees and tmux sessions for reviewing PRs, fixing issues, and building features. It supports GitHub and Jira project references, aliases, and attach/kill/status session commands.

**Install:**

```bash
npx degit https://github.com/Yeachan-Heo/oh-my-claudecode/tree/main/skills/project-session-manager ~/.claude/skills/project-session-manager
```

## README

# 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

| 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.

## 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.

| Type | Public ID (`psm attach`/`kill`) | Tmux Session (`tmux attach -t`) | Worktree Dir |
|------|---------------------------------|---------------------------------|--------------|
| PR Review | `omc:pr-123` | `psm_omc_pr-123` | `~/.psm/worktrees/omc/pr-123` |
| Issue Fix | `omc:issue-42` | `psm_omc_issue-42` | `~/.psm/worktrees/omc/issue-42` |
| Feature | `omc:feat-auth` | `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:
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**:
   ```bash
   # 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
   ```

2. **Fetch PR info**:
   ```bash
   gh pr view <pr_number> --repo <repo> --json number,title,author,headRefName,baseRefName,body,files,url
   ```

3. **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
   ```

4. **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"
   ```

5. **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
   ```

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

7. **Create tmux session** (tmux-safe name; `:`/`.` are translated to `_`):
   ```bash
   tmux new-session -d -s "psm_${project_alias}_pr-$pr_number" -c "$worktree_path"
   ```

8. **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
   ```

9. **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)

2. **Fetch issue info**:
   ```bash
   gh issue view <issue_number> --repo <repo> --json number,title,body,labels,url
   ```

3. **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
   ```

4. **Create worktree**:
   ```bash
   worktree_path="$HOME/.psm/worktrees/$project_alias/issue-$issue_number"
   git worktree add "$worktree_path" "$branch_name"
   ```

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

6. **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**:

1. **Resolve project** (from alias or path)

2. **Create feature branch**:
   ```bash
   cd "$local_path"
   git fetch origin main
   branch_name="feature/$feature_name"
   git checkout -b "$branch_name" origin/main
   ```

3. **Create worktree**:
   ```bash
   worktree_path="$HOME/.psm/worktrees/$project_alias/feat-$feature_name"
   git worktree add "$worktree_path" "$branch_name"
   ```

4. **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**:

1. **Read sessions registry**:
   ```bash
   cat ~/.psm/sessions.json 2>/dev/null || echo '{"sessions":{}}'
   ```

2. **Check tmux sessions**:
   ```bash
   tmux list-sessions -F "#{session_name}" 2>/dev/null | grep "^psm_"
   ```

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

4. **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`

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

3. **Attach**:
   ```bash
   tmux attach -t "psm_${session_id//[.:]/_}"
   ```

### Subcommand: `kill <session>`

**Purpose**: Kill session and cleanup

**Steps**:

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

2. **Remove worktree**:
   ```bash
   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
   ```

3. **Update registry**:
   ```bash
   # Remove from sessions.json
   ```

### Subcommand: `cleanup`

**Purpose**: Clean up merged PRs and closed issues

**Steps**:

1. **Read all sessions**

2. **For each PR session, check if merged**:
   ```bash
   gh pr view <pr_number> --repo <repo> --json merged,state
   ```

3. **For each issue session, check if closed**:
   ```bash
   gh issue view <issue_number> --repo <repo> --json closed,state
   ```

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

5. **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:
   ```bash
   tmux display-message -p "#{session_name}" 2>/dev/null
   # or check if cwd is inside a worktree
   ```

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

3. **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

```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

```
~/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
```
