Import Existing AI Config

Convert existing target-specific AI configuration files into universal-ai-config templates. The user must specify which target to import from.

Usage

The user should specify the source target: claude, copilot, or cursor.

Import Process

1. Identify Source Files

Scan the target's config directory for existing configuration files:

Claude (.claude/):

• Instructions: .claude/rules/*.md — each file has description and optional paths frontmatter
• Skills: .claude/skills/*/SKILL.md — skill directories with frontmatter (name, description, allowed-tools, model, context, agent, disable-model-invocation, user-invocable, argument-hint, hooks). Skill directories may also contain extra supporting files (references, examples, scripts) alongside SKILL.md.
• Agents: .claude/agents/*.md — agent files with frontmatter (name, description, tools, disallowedTools, permissionMode, skills, hooks, memory, model)
• Hooks: .claude/settings.json → hooks key — JSON with PascalCase event names (SessionStart, SessionEnd, UserPromptSubmit, PreToolUse, PostToolUse, PostToolUseFailure, Stop, SubagentStart, SubagentStop, PreCompact, PermissionRequest, Notification)
• MCP: .mcp.json — JSON with mcpServers wrapper containing server configs (type, command, args, env, url, headers)
• Commands (deprecated): .claude/commands/*.md — single-file slash commands with optional frontmatter (description, allowed-tools, argument-hint, model). May include subdirectories for namespacing (e.g. .claude/commands/frontend/component.md — command name is component). Body may use $ARGUMENTS placeholder, ! prefix for bash execution, and @ prefix for file references.

Copilot (.github/):

• Instructions: .github/copilot-instructions.md (always-apply) and .github/instructions/*.instructions.md (with applyTo frontmatter)
• Skills: .github/skills/*/SKILL.md — skill directories with frontmatter (name, description, license, compatibility, metadata). May contain extra supporting files alongside SKILL.md.
• Agents: .github/agents/*.agent.md — agent files with frontmatter (name, description, tools, model, target, mcp-servers, handoffs)
• Hooks: .github/hooks/hooks.json — JSON with version field and camelCase event names (sessionStart, sessionEnd, userPromptSubmitted, preToolUse, postToolUse, errorOccurred)
• MCP: .vscode/mcp.json — JSON with servers wrapper (not mcpServers), may include inputs array for interactive secret prompts

Cursor (.cursor/):

• Instructions: .cursor/rules/*.mdc or .cursor/rules/*.md — with description, globs, alwaysApply frontmatter
• Skills: .cursor/skills/*/SKILL.md — skill directories with frontmatter (name, description, license, compatibility, metadata, disable-model-invocation). May contain extra supporting files alongside SKILL.md.
• Hooks: .cursor/hooks.json — JSON with version field and camelCase event names (sessionStart, sessionEnd, beforeSubmitPrompt, preToolUse, postToolUse, postToolUseFailure, stop, subagentStart, subagentStop, preCompact, plus Cursor-specific events like beforeShellExecution, afterFileEdit)
• MCP: .cursor/mcp.json — JSON with mcpServers wrapper, omits type field (Cursor infers transport from command vs url)
• Note: Cursor does not have agents

2. Convert to Universal Format

For each file found, convert it to a universal-ai-config template:

Frontmatter mapping (target-specific → universal):

Claude	Copilot	Cursor	Universal
paths	applyTo	globs	globs
(no paths field)	(copilot-instructions.md)	alwaysApply: true	alwaysApply: true
disable-model-invocation	—	disable-model-invocation	disableAutoInvocation
user-invocable	—	—	userInvocable
allowed-tools	—	—	allowedTools
context: fork	—	—	forkContext: true
agent	—	—	subagentType
argument-hint	—	—	argumentHint
hooks	—	—	hooks
(commands: manual-only)	—	—	disableAutoInvocation
—	excludeAgent	—	excludeAgent
—	license	license	license
—	compatibility	compatibility	compatibility
—	metadata	metadata	metadata
—	target	—	target

Hook event mapping (target-specific → universal):

Claude	Copilot	Cursor	Universal
SessionStart	sessionStart	sessionStart	sessionStart
SessionEnd	sessionEnd	sessionEnd	sessionEnd
UserPromptSubmit	userPromptSubmitted	beforeSubmitPrompt	userPromptSubmit
PreToolUse	preToolUse	preToolUse	preToolUse
PostToolUse	postToolUse	postToolUse	postToolUse
PostToolUseFailure	—	postToolUseFailure	postToolUseFailure
Stop	—	stop	stop
SubagentStart	—	subagentStart	subagentStart
SubagentStop	—	subagentStop	subagentStop
PreCompact	—	preCompact	preCompact
PermissionRequest	—	—	permissionRequest
Notification	—	—	notification
—	errorOccurred	—	errorOccurred

Cursor-specific events (e.g. beforeShellExecution, afterFileEdit) should be preserved as-is — they pass through to Cursor and are dropped for other targets.

Hook handler field mapping:

Claude	Copilot	Cursor	Universal
command	bash	command	command
timeout	timeoutSec	timeout	timeout
matcher (in parent group)	—	matcher	matcher

MCP server conversion (target-specific → universal):

The universal MCP format uses mcpServers as the wrapper key, with each server having type, command, args, env, url, and headers fields.

Source	Conversion
Claude .mcp.json	Copy mcpServers as-is (already matches universal format)
Copilot .vscode/mcp.json	Rename servers → mcpServers, add type field if missing, copy inputs
Cursor .cursor/mcp.json	Copy mcpServers, add type: "stdio" for servers with command (Cursor omits it)

3. Write Universal Templates

For each converted file:

1. Use the same base name as the source file (e.g. .claude/rules/coding-style.md → <%= instructionTemplatePath('coding-style') %>)
2. Write the universal frontmatter and body content. Copy and paste the body content, instead of trying to use EJS include() or something equivalent, because the source files will be deleted afterwards.
3. If a template with the same name already exists, overwrite it (the import represents the latest version)

File placement:

• Instructions → <%= instructionTemplatePath('{name}') %>
• Skills → <%= skillTemplatePath('{name}') %>
• Agents → <%= agentTemplatePath('{name}') %>
• Hooks → <%= hookTemplatePath('{source-name}') %>
• MCP → <%= mcpTemplatePath('{source-name}') %>
• Commands → <%= skillTemplatePath('{name}') %> (commands convert to skills)

4. Handle Special Cases

• Claude hooks: Extract the hooks key from .claude/settings.json. Flatten the nested matcher group structure into individual handlers with matcher fields.
• Copilot always-apply: Convert .github/copilot-instructions.md to an instruction with alwaysApply: true.
• Copilot hook bash field: Convert to universal command field.
• Copilot hook timeoutSec field: Convert to universal timeout field (both use seconds).
• Cursor .mdc files: Read as regular markdown (the .mdc extension is just a convention).
• Copilot MCP servers key: Rename to mcpServers in the universal template.
• Copilot MCP inputs array: Preserve as-is — it's included in Copilot output only, ignored by Claude/Cursor.
• Cursor MCP missing type: Add "type": "stdio" for servers with command, or "type": "sse" for servers with url.
• MCP env var references: Leave ${ENV_VAR} syntax as-is — it's passed through to generated output. If values look like they could be config variables, consider converting to {{varName}} syntax and adding a variables entry in the config file.
• Fields that only exist for one target: Preserve them as-is. They'll be passed through to matching targets and ignored by others.
• Skill extra files: When importing skill directories, copy all files in the directory — not just SKILL.md. Extra files (references, examples, scripts, data) should be placed in the same relative paths within the universal template's skill directory (e.g. .claude/skills/my-skill/references/example.md → <%= skillTemplatePath('my-skill') %>/../references/example.md, i.e. skills/my-skill/references/example.md in the templates dir). During generation, .md extra files are rendered through EJS (with access to target, config, path helpers), while non- files are copied as-is.

5. Verify

After importing, run uac generate targeting all configured targets and compare the generated output against the original source files to ensure the conversion is accurate.

Report to the user:

• How many files were imported per type
• Any files that couldn't be converted (with reasons)
• Whether the generated output matches the originals
