justsisyphus 9d815a5697 feat(skill-mcp): add auto-reconnect retry on "Not connected" errors
- Added withOperationRetry<T>() helper method that retries operations up to 3 times
- Catches "Not connected" errors (case-insensitive)
- Cleans up stale client before retry
- Modified callTool, readResource, getPrompt to use retry logic
- Added tests for retry behavior (3 new test cases)

before the headers assertion.

stranger2904 0169035f0f test: mock StreamableHTTPClientTransport for faster, deterministic tests
Add mocks for HTTP transport to avoid real network calls during tests.
This addresses reviewer feedback about test reliability:
- Tests are now faster (no network latency)
- Tests are deterministic across environments
- Test intent is clearer (unit testing error handling logic)

The mock throws immediately with a controlled error message,
allowing tests to validate error handling without network dependencies.

stranger2904 7ec6d202ee feat(skill-mcp): add HTTP transport support for remote MCP servers
Add support for connecting to remote MCP servers via HTTP in addition to
the existing stdio (local process) connections. This enables skills to
use cloud-hosted MCP servers and aggregated MCP gateways.

## Changes

- Extend SkillMcpManager to detect connection type from config:
  - Explicit `type: "http"` or `type: "sse"` → HTTP connection
  - Explicit `type: "stdio"` → stdio connection
  - Infer from `url` field → HTTP connection
  - Infer from `command` field → stdio connection

- Add StreamableHTTPClientTransport from MCP SDK for HTTP connections
  - Supports custom headers for authentication (e.g., API keys)
  - Proper error handling with helpful hints

- Maintain full backward compatibility with existing stdio configurations

## Usage

```yaml
# HTTP connection (new)
mcp:
  remote-server:
    url: https://mcp.example.com/mcp
    headers:
      Authorization: Bearer ${API_KEY}

# stdio connection (existing, unchanged)
mcp:
  local-server:
    command: npx
    args: [-y, @some/mcp-server]
```

## Tests

Added comprehensive tests for:
- Connection type detection (explicit type vs inferred)
- HTTP URL validation and error messages
- Headers configuration
- Backward compatibility with stdio configs

Sisyphus 70510a549d fix(skill-mcp-manager): filter npm/pnpm/yarn env vars that break MCP servers (#459)
When running in pnpm projects, the .npmrc configuration propagates as
NPM_CONFIG_* environment variables to child processes. This can cause
MCP servers to fail due to registry/proxy conflicts or case sensitivity
issues between uppercase and lowercase variants.

This fix adds a createCleanMcpEnvironment function that filters out:
- NPM_CONFIG_* and npm_config_* (npm/pnpm config)
- YARN_* (yarn config)
- PNPM_* (pnpm config)
- NO_UPDATE_NOTIFIER

Fixes #456

YeonGyu-Kim fbb921c5c2 fix(skill-mcp-manager): prevent memory leaks from orphaned MCP processes (#453)
* fix(skill-mcp-manager): prevent memory leaks from orphaned MCP processes

- Close transport on connection failure to prevent zombie processes
- Add process exit handlers (SIGINT/SIGTERM) for graceful cleanup
- Use pendingConnections Map to prevent duplicate client spawns

Fixes #361

* fix(ci): replace deprecated rhysd/actionlint-action with direct installation

rhysd/actionlint-action repository was removed/archived.
Use official actionlint download script instead.

* fix(skill-mcp-manager): add transport.close() and idle timeout to fix memory leaks

Previously, disconnectSession() and disconnectAll() only called client.close() but NOT transport.close().
StdioClientTransport spawns child processes for MCP servers, and without transport.close(), these
processes remained orphaned and accumulated memory (6GB leak reported).

Changes:
- Added missing transport.close() calls in disconnectSession() and disconnectAll()
- Added idle timeout mechanism (5-minute timeout) with lastUsedAt tracking
- Added cleanup timer that runs every 60 seconds to remove idle clients
- Made signal handlers (SIGINT, SIGTERM, SIGBREAK) async to properly await cleanup
- Ensure proper cleanup order: clear from map first, then close client, then close transport

* fix(ci): pin actionlint download script to v1.7.10 for supply chain security

- Pin to specific release tag instead of 'main' branch
- Prevents potential supply chain attacks from upstream compromises

- Always merge parent process.env when spawning MCP child processes
- Overlay config.env on top if present (for skill-specific overrides)
- Fixes issue where skills without explicit env: block started with zero environment variables
- Adds 2 tests for env inheritance behavior
