Copilot CLI

The standalone Copilot CLI supports plugin installation from GitHub repos. Copilot CLI reads the same .claude-plugin/marketplace.json manifest this repo uses, so the marketplace and child-plugin layout works without modification.

TMDL files have a problem with repository-relative paths over 260 characters. Windows' legacy MAX_PATH blocks git clone from writing them unless long path support is enabled at both the OS and git level. Without this, copilot plugin install aborts with Filename too long.

Check useful-stuff/agent-scripts/enable-windows-longpaths.ps1 as an example of a script you can run from an elevated ps environment to enable long paths; there are other routes to do this that you can find online, too... just ask Copilot. A reboot is recommended after the registry change. This is a Windows OS limitation, documented at Maximum Path Length Limitation.

See also the below git config command:

git config --system core.longpaths true

This repository is an Anthropic-format plugin marketplace (a set of plugins), not a single distributable plugin, so the root .claude-plugin/ contains only marketplace.json. Two documented install paths work:

1. Register the marketplace once, then install named child plugins. Example:

copilot plugin marketplace add data-goblin/power-bi-agentic-development
copilot plugin install tabular-editor@power-bi-agentic-development

2. Or install a single plugin directly from its subdirectory, no marketplace registration needed. Example:

copilot plugin install data-goblin/power-bi-agentic-development:plugins/pbip

Both forms are documented in the Copilot CLI plugin reference and the plugins how-to. Inside an interactive Copilot session, /plugin install PLUGIN-NAME@MARKETPLACE-NAME is the equivalent of (1). The bare copilot plugin install data-goblin/power-bi-agentic-development (no qualifier) will not install anything useful, because the root is a marketplace catalog, not a plugin.

Inside Copilot CLI:

/env                    # Loaded instructions, MCP servers, skills, agents, plugins, LSPs, extensions
/plugin list            # Installed plugins
/skills list            # Available skills
/skills info pbip       # Details for a specific skill
/agent                  # Browse installed agents

• Skills load identically; Copilot CLI reads skills/<name>/SKILL.md.
• Agents use the *.agent.md extension required by Copilot CLI's documented convention. Claude Code matches any *.md file in agents/, so the dual extension works in both tools.
• MCP servers load from .mcp.json (plugin root) or .github/mcp.json. The plugins in this repo do not currently ship MCP servers.
• Hooks are registered via hooks.json and reference scripts using ${CLAUDE_PLUGIN_ROOT}. Copilot CLI ≥ 1.0.26 (2026-04-14) sets CLAUDE_PLUGIN_ROOT for plugin hooks (changelog); older builds do not, which causes hook commands to resolve to broken paths. Run copilot update if hooks fail to fire. Native Windows bash users may also hit a separate path-format bug tracked upstream at claude-code#11984.

Overview

The repo contains skills, agents, and hooks.

• Skills teach agents domain knowledge and workflows. They activate automatically based on task context, or can be invoked manually with /skill-name. In Claude Code, skills and commands have coalesced; commands are simply more prescriptive skill workflows.
• Agents are autonomous subprocesses that handle complex, multi-step tasks independently; typically used for review and validation.
• Hooks run automatically after tool use to validate files and catch errors early. They are deterministic; they fire when a specific pattern is matched, not by LLM judgment.

Hook checks can be individually toggled via config files. Set any check to false to disable it:

• plugins/pbip/hooks/config.yaml -- PBIR, TMDL, and report binding validation
• plugins/pbi-desktop/hooks/config.yaml -- DAX references, measure metadata, referential integrity, metadata cache
