Current adapter does not support ${description}

Error message

Current adapter does not support ${description}

What it means

The requested debug action needs a DAP capability (e.g. disassembly, conditional breakpoints, restart) that the connected adapter did not advertise as `true` in its DAP Capabilities response. requireCapability checks `dapSessionManager.getCapabilities()[capability] !== true` after confirming an active session exists. The tool fails fast instead of sending a request the adapter would reject or mishandle.

Solutions

1. Use an adapter/runtime that supports the capability (e.g. for disassembly use an adapter that reports supportsDisassembleRequest).
2. Drop or replace the unsupported action with one the adapter advertises.
3. Upgrade the adapter binary/config in the workspace DAP adapter config to a version that supports the feature.
4. Read the session capabilities snapshot and branch your automation on it before issuing the action.

Example fix

// before
debugTool({ action: "disassemble", memory_reference: "0x1000" }) // debugpy lacks support
// after
debugTool({ action: "stack_trace" }) // pick an action the adapter supports, or attach with a capable adapter

const caps = await debugTool({ action: "snapshot" }); // snapshot exposes adapter capabilities
if (!caps.capabilities?.supportsDisassembleRequest) {
  // skip disassemble or switch adapter
}

function supports(cap: Record<string, unknown> | undefined, key: string): cap is Record<string, unknown> {
  return !!cap && cap[key] === true;
}

try {
  return await debugTool({ action: "disassemble", memory_reference });
} catch (e) {
  if (String(e).startsWith("Current adapter does not support")) {
    return null; // feature unsupported by this adapter
  }
  throw e;
}

When it happens

Trigger: Calling an action gated behind a capability (requireCapability call sites in execute) — e.g. disassemble, restart, or other feature-specific actions — against an adapter whose capabilities response reports the feature as false or omits it.

Common situations: Using disassemble with debugpy (no disassembly support); expecting restart-frame behavior on adapters that don't implement it; an older adapter version lacking a newer DAP feature; attaching to a runtime with limited DAP support.
