GiDev Server Operations

Directive knowledge for GiDev server-specific operations: worktrees, tmux, Caddy routing, and dev tooling.

When to Use This Skill

Load this skill when you need to:

• Create or manage git worktrees
• Work with tmux sessions
• Configure Caddy routing for dev URLs
• Use start-work/stop-work scripts
• Understand port allocation
• Query the project registry

For AWS/DNS/credentials: Use af-environment-infrastructure instead.

Quick Reference

Key Locations

Port Allocation Formula

ISSUE_NUM="${ISSUE_KEY##*-}"           # Extract number from JCN-123
MAIN_PORT=$((PORT_BASE + ISSUE_NUM))   # Main app
STORYBOOK_PORT=$((PORT_BASE + 3000 + ISSUE_NUM))  # Storybook
TEST_REPORT_PORT=$((PORT_BASE + 6000 + ISSUE_NUM)) # Test reports

Project Port Bases

Rules

Worktree Rules (MUST)

1. MUST use start-work to create worktrees. Never manually create worktrees - the script handles port allocation, Caddy config, and tmux.

2. MUST use stop-work to clean up. It removes Caddy configs, kills processes, and deletes the worktree properly.

3. MUST NOT switch branches in a worktree. Each worktree is dedicated to one issue. Ask user permission before any git checkout or git switch.

Caddy Rules (MUST)

4. MUST use http:// prefix in Caddy configs. Traffic comes through Cloudflare Tunnel which handles HTTPS:

   caddyCopy

   http://jcn-4.gaininsight.co.uk {
       reverse_proxy localhost:23004
   }
   

5. MUST reload Caddy after config changes:

   bashCopy

   sudo caddy reload --config /etc/caddy/Caddyfile
   

Permission Rules (SHOULD)

6. SHOULD run fix-permissions if encountering permission errors. Worktrees need correct ownership for shared access.

7. SHOULD use project-registry to check project config before making assumptions.

Workflows

Workflow: Start Work on an Issue

When: Beginning work on a Linear issue

Command:

start-work {project} {ISSUE-KEY}
# Example: start-work juncan JCN-4

What happens:

1. Creates worktree at /srv/worktrees/{project}/{ISSUE-KEY}
2. Allocates ports based on issue number
3. Creates Caddy configs for main app, storybook, test reports
4. Creates tmux session named {ISSUE-KEY}
5. Generates PORT_INFO.md with allocated ports
6. Runs .start-work-hooks if present

After starting:

tmux attach -t JCN-4   # Attach to session
cat PORT_INFO.md       # See allocated ports

Workflow: Stop Work on an Issue

When: Finished with an issue or need to clean up

Command:

stop-work {ISSUE-KEY}
# Example: stop-work JCN-4

What happens:

1. Runs .stop-work-hooks if present (cleanup, sandbox deletion)
2. Kills tmux session
3. Removes Caddy configs
4. Deletes worktree

Workflow: Fix Permission Issues

When: Encountering "permission denied" errors in worktrees

Command:

fix-permissions
# Or for specific worktree:
fix-permissions /srv/worktrees/juncan/JCN-4

Workflow: Query Project Configuration

When: Need to know project settings

Commands:

project-registry list              # List all projects
project-registry juncan            # Show project config
project-registry juncan aws        # Show AWS accounts
project-registry accounts          # List all AWS accounts
project-registry validate          # Validate registry file

Common Pitfalls

Essential Reading

Remember:

1. Use start-work/stop-work, not manual worktree commands
2. Caddy configs use http:// (Cloudflare handles HTTPS)
3. Don't switch branches in worktrees without permission
4. Run fix-permissions for ownership issues
