name: flutter-mcp-toolkit-intentcall-migration description: >- Migrate Flutter app code from removed MCPCallEntry to AgentCallEntry after the hard cut. Use when upgrading mcp_toolkit, fixing compile errors after a major bump, or running flutter-mcp-toolkit migrate agent-entries.

IntentCall migration — MCPCallEntry → AgentCallEntry

MCPCallEntry is removed from mcp_toolkit. App code must use AgentCallEntry (from intentcall_core, re-exported by mcp_toolkit).

Canonical migration doc: migration_mcp_call_entry_to_agent_call_entry.md

When to use this skill

• dart analyze reports undefined MCPCallEntry after upgrading mcp_toolkit
• User asks to migrate custom tools/resources to the new API
• Before shipping a major mcp_toolkit bump to consumers

CLI (preferred)

# Preview (exit 1 if changes pending)
flutter-mcp-toolkit migrate agent-entries --check lib/

# Apply
flutter-mcp-toolkit migrate agent-entries --write lib/
flutter-mcp-toolkit migrate agent-entries --write --namespace my_app lib/main.dart

Alias: migrate mcp-call-entry (same behavior).

After migration — registration

• MCPToolkitBinding.addEntries(entries: Set<AgentCallEntry>)
• addEntries(entries: { ... }) before bootstrapFlutter(runApp: ...)
• addMcpTool(AgentCallEntry) — still a shortcut for a single entry

Handlers should return AgentResult (AgentResult.success / AgentResult.failure). For legacy MCPCallResult + MCPToolDefinition handlers, use mcpToolkitTool / mcpToolkitResource (see flutter-mcp-toolkit-custom-tools).

Legacy pattern (before — do not ship new code)

// BEFORE (removed in Phase 6b)
final tool = MCPCallEntry.tool(
  handler: (request) async => MCPCallResult(
    message: 'ok',
    parameters: {'n': request['n']},
  ),
  definition: MCPToolDefinition(
    name: 'my_tool',
    description: 'Example',
    inputSchema: {'type': 'object', 'properties': {}},
  ),
);

Target pattern (after)

import 'package:mcp_toolkit/mcp_toolkit.dart';

final tool = AgentCallEntry.tool(
  namespace: 'app',
  name: 'my_tool',
  description: 'Example',
  inputSchema: const {
    'type': 'object',
    'additionalProperties': false,
    'properties': {'n': {'type': 'string'}},
    'required': ['n'],
  },
  handler: (final args) async {
    final n = args['n']?.toString() ?? '';
    return AgentResult.success(
      message: 'ok',
      data: {'n': n},
    );
  },
);

await MCPToolkitBinding.instance.addEntries(entries: {tool});

Platform sync (optional)

After tool surfaces compile:

flutter-mcp-toolkit codegen sync --platform web
flutter-mcp-toolkit codegen sync --platform android,ios,macos --check

See docs/platform-notes/android-oem.md for Xiaomi/Huawei (same shortcuts XML as AOSP).

MCP migrate tool

fmt_migrate_agent_entries is shipped (report-only by default; apply: true to rewrite). CLI equivalent: flutter-mcp-toolkit migrate agent-entries.

Maintainer checklist (in-repo product gate)

1. flutter-mcp-toolkit migrate agent-entries --check on showcase/flutter_test_app/lib
2. make sync-skills after any plugin/skills/ edit
3. cd mcp_server_dart && dart test test/contract/
4. Grep: no MCPCallEntry in skills except this file's BEFORE examples

Hosted IntentCall packages

IntentCall now lives outside this repository. Normal consumer state uses hosted intentcall_* packages.

1. Use hosted intentcall_*: ^0.6.0 dependencies for committed consumer state.
2. Use local path overrides only for deliberate cross-repo development against a local IntentCall checkout.
3. Run flutter pub get and migrate agent-entries --check again after dependency changes.
4. CI: use make check-intentcall-hosted-consumer for hosted mcp_flutter proof; use make check-intentcall-sibling-matrix only for deliberate local IntentCall checkout matrix proof. The historical make check-intentcall-integration target is a compatibility alias for the sibling-matrix lane, not a fresh-adopter hosted gate.
