Agent Skills: Setup — Prerequisites & MCP Configuration

Setup — Prerequisites & MCP Configuration

Install CLI tools, authenticate to GitHub/GitLab, and configure the mcp-atlassian Jira integration for OpenCode.

Prerequisites

• Linux with apt package manager
• bash and curl available
• Internet access (for apt packages and uv installer)

Trigger

User says: "setup", "install prerequisites", "configure jira", or similar.

Important — interactive skill only. This skill requires user interaction (auth prompts, Jira credentials). It must not be called as a sub-step from autonomous skill pipelines (fast-meeting, issue-review, etc.) — doing so will stall the pipeline waiting for input that will never arrive.

Workflow

Phase 1 — Install CLI tools

Run the bundled script to install missing tools (idempotent — skips already-installed ones):

bash "$(dirname "$0")/reference/setup.sh"

The script installs (via apt if not already present):

• gh — GitHub CLI
• glab — GitLab CLI
• jq — JSON processor
• uvx — via the official uv installer (curl -LsSf https://astral.sh/uv/install.sh | sh)

After running, inform the user of what was installed vs. already present.

Phase 2 — CLI Authentication

Check and authenticate each CLI:

gh auth status 2>&1

• Show the full output to the user (current logged-in account, token scopes, etc.)
• If not authenticated → tell the user: "Run gh auth login and follow the prompts."
• Do NOT run gh auth login automatically (requires interactive input).

glab auth status 2>&1

• Show the full output to the user (GitLab instance, current user, token validity, etc.)
• If not authenticated → tell the user: "Run glab auth login and follow the prompts."
• Do NOT run glab auth login automatically.

Phase 3 — Configure mcp-atlassian for Jira

Step 3.1 — Check if uvx is available:

uvx --version 2>&1 || ~/.local/bin/uvx --version 2>&1

If not found, remind the user to restart their shell or source ~/.bashrc / ~/.profile after the Phase 1 script ran.

Step 3.2 — Read existing OpenCode config:

Use the Read tool to read ~/.config/opencode/opencode.json.

• If the file does not exist, treat it as {}.
• If mcp.mcp-atlassian is already present → confirm to the user and skip the rest of Phase 3.

Step 3.3 — Gather credentials (if not already configured):

Ask the user these two questions in a single message:

1. Jira URL — default https://jira.dedalus.com/ (Server/Data Center). Press Enter to accept.
2. Jira Personal Access Token (PAT) — steps to generate one:
   • Log in to your Jira instance
   • Go to Profile → Personal Access Tokens
   • Click Create token, give it a name, set an expiry
   • Copy the token and paste it here

For Jira Cloud users: use JIRA_USERNAME (your email) + JIRA_API_TOKEN (from https://id.atlassian.com/manage-profile/security/api-tokens) instead of a PAT.

Step 3.4 — Write the config:

Merge the mcp-atlassian block into ~/.config/opencode/opencode.json, preserving any existing content. Use the Write tool to write the final JSON.

For Server/Data Center (default):

{
  "mcp": {
    "mcp-atlassian": {
      "type": "local",
      "command": ["uvx", "mcp-atlassian"],
      "environment": {
        "JIRA_URL": "<jira-url>",
        "JIRA_PERSONAL_TOKEN": "<pat>"
      },
      "enabled": true
    }
  }
}

For Cloud (if user specifies):

{
  "mcp": {
    "mcp-atlassian": {
      "type": "local",
      "command": ["uvx", "mcp-atlassian"],
      "environment": {
        "JIRA_URL": "<jira-url>",
        "JIRA_USERNAME": "<email>",
        "JIRA_API_TOKEN": "<api-token>"
      },
      "enabled": true
    }
  }
}

Step 3.5 — Secure the config file:

chmod 600 ~/.config/opencode/opencode.json

Phase 4 — Summary

Print a clear summary table:

| Component | Status | |-----------|--------| | gh | installed / already ok | | glab | installed / already ok | | jq | installed / already ok | | uvx | installed / already ok | | gh auth | authenticated / action needed | | glab auth | authenticated / action needed | | mcp-atlassian | configured / already ok / skipped |

End with: "Restart OpenCode to load the new MCP configuration."
