Bug Report

Feature Area: agents skill CLI — skill refresh / MCP sync
Severity: Critical — agents skill refresh silently does nothing for MCP-backed skills
Found by: UAT Testing (tool-router-mcp-adapter area)

What Was Tested

Code-level analysis of src/cleveragents/cli/commands/skill.py — specifically the refresh command (lines 916–1132) and its MCP sync behavior.

Expected Behavior (from spec)

The agents skill refresh command should:

Re-enumerate available tools from connected MCP servers
Update the skill's tool list with any new/removed tools from the MCP server
Report the sync status accurately

Actual Behavior

The refresh command contains a TODO stub that does nothing for MCP-backed skills:

# Check for MCP servers
has_mcp = len(skill.mcp_servers) > 0
mcp_status = "synced" if has_mcp else "n/a"

# For MCP skills, we would sync here if MCP adapter was available
# Currently, we just mark as refreshed
if has_mcp:
    # TODO: When MCP adapter integration is available, call
    # mcp_adapter.refresh_tools() for each server
    pass

The command then reports mcp_status = "synced" even though no actual sync occurred. Users running agents skill refresh local/my-mcp-skill will see a success message claiming MCP servers are "synced" when in reality no connection was made and no tools were refreshed.

Code Location

Bug: src/cleveragents/cli/commands/skill.py, lines 1017–1025 (TODO stub in refresh command)

Impact

Silent data staleness: MCP-backed skills never get updated tool lists after initial registration
Misleading output: The command reports mcp_status: synced when no sync occurred
User trust: Users cannot rely on agents skill refresh to pick up new tools from MCP servers
This is a v3.3.0 milestone deliverable (MCP adapter + skill management)

Fix

Implement actual MCP sync in the refresh command:

if has_mcp:
    from cleveragents.mcp.adapter import MCPToolAdapter, MCPServerConfig
    for mcp_server in skill.mcp_servers:
        config = MCPServerConfig(
            name=mcp_server.server,
            transport=mcp_server.transport or "stdio",
            command=mcp_server.command,
            url=mcp_server.url,
        )
        adapter = MCPToolAdapter(config=config)
        try:
            adapter.connect()
            tools = adapter.discover_tools()
            # Update skill's tool list with discovered tools
            adapter.disconnect()
            mcp_status = "synced"
        except Exception as e:
            mcp_errors.append(f"{skill.name}/{mcp_server.server}: {e}")
            mcp_status = "failed"

Metadata

Commit Message: fix(skill): implement MCP tool sync in agents skill refresh command
Branch: fix/skill-refresh-mcp-sync

Subtasks

Remove the TODO stub and implement actual MCP adapter connection in refresh
Connect to each MCP server listed in the skill's mcp_servers
Discover tools and update the skill's tool list
Report accurate sync status (synced/failed) per server
Add unit tests for MCP sync in refresh command
Handle connection failures gracefully (partial sync)

Definition of Done

agents skill refresh <name> actually connects to MCP servers and re-enumerates tools
Sync status accurately reflects whether the connection succeeded
Failed MCP connections are reported as errors, not silently ignored
All existing tests pass

Issue triaged by project owner:

State: Verified
Priority: High — (adjusting from Critical) agents skill refresh MCP sync is a silent no-op stub. Users who run this command to refresh MCP tool discovery get no error and no result — the command silently does nothing.
Milestone: v3.2.0 — skill management is a core v3.2.0 feature
Story Points: 3 — M — requires implementing the MCP sync logic in the skill refresh command
MoSCoW: Should Have — skill refresh is documented functionality. The workaround is to re-register the skill, but the command should work as documented.
Parent Epic: Needs linking to the skills/MCP epic

Triage Rationale: A silent no-op stub is a spec compliance gap. Users expect skill refresh to update MCP tool discovery. The fix requires implementing the actual MCP sync logic.
