Dockhand Guardrails

Enforce safety policies for infrastructure operations, preventing common mistakes and ensuring best practices across all Dockhand workflows.

Platform Domain Context

IMPORTANT: When working with domains in ANY Dockhand operation, you MUST use the user's actual configured domain, never example placeholders.

How to discover the user's domain:

1. Primary method: Call dns_list_records - the zone shows their platform_domain
2. From apps: Call dokploy_list_apps - app domains reveal the platform domain
3. From certs: Call traefik_check_certs - shows active domains
4. Config location: ~/.config/dockhand/config.json contains "platform_domain": "actual-domain.com"

Always substitute <platform_domain> placeholders with the discovered domain before executing DNS or domain-related operations.

Core Rules

1. No secrets in git - Never commit .env files, passwords, tokens, or API keys. Warn immediately if user attempts to stage sensitive files.

2. Environment-based Terraform workflow:

   • Production: All changes require PR to main branch. Block direct terraform apply on prod.
   • Test environments: Direct apply allowed with confirmed=true.

3. Destructive operation gating - Block dangerous commands without explicit confirmation:

   • terraform destroy
   • docker rm, docker volume rm
   • rm -rf on infrastructure paths
   • Database drops or truncates

4. Backup before modify - Require backup verification before:

   • Database migrations
   • Volume modifications
   • Service downgrades

5. State sync after deploy - Prompt to run state collection after Dokploy deployments to maintain git documentation.

Intervention Triggers

Intervene when user requests:

Enforcement Behavior

• Monitor all tool calls passively
• Block destructive operations on protected branches (main, master, production)
• Require confirmed=true for state-changing MCP tools
• Log audit trail for infrastructure changes via notify_send if configured

Mode-Aware Enforcement

Admin Mode

Full guardrail enforcement via both plugin hooks and MCP server:

• terraform_apply - Requires confirmed=true
• dokploy_redeploy - Requires confirmed=true
• dns_create_record, dns_update_record, dns_delete_record - Require confirmed=true
• ssh_exec - Blocks destructive commands without confirmation

Client Portal Mode

Server-side enforcement only. The remote MCP server scopes access based on the user's portal token:

• Users can only access apps assigned to their account
• Destructive operations require server-side approval
• No direct SSH, Terraform, or raw infrastructure access
• The plugin hooks allow all dockyard_* tool calls through (server enforces permissions)

This skill provides the policy layer; MCP tools provide enforcement.
