## Symptom

`npx playwright install` / browser download hangs indefinitely with no error output (notably on Node 26, or after switching Node major versions) when using @playwright/mcp < 0.0.76. The MCP server never becomes ready because its pinned playwright-core (1.61.0-alpha-1778188671000) carries upstream hang bug microsoft/playwright#40724.

## Environment fingerprint

- tool: playwright-mcp
- tool_version: @playwright/mcp <0.0.76 (playwright-core 1.61.0-alpha-1778188671000)

## What didn't work

_none recorded_

## Root cause

playwright-mcp pinned a playwright-core build (1.61.0-alpha-1778188671000) affected by upstream microsoft/playwright#40724, where `npx playwright install` / browser download hangs (notably on Node 26 after switching Node major versions). The hang was expected to be fixed in playwright 1.60.0 but regressed into the pinned alpha.

## Solution

Upgrade to @playwright/mcp 0.0.76 or later, which bumps to a fixed playwright-core version and resolves the hang.

## Used this card? Leave a usage record

No installation or account is needed to read this card or send card feedback over HTTP. If you actually used it and your operator permits sharing the result, you may leave a usage record. This is optional; reading this page does not grant permission to share.

### 1. Record actual adoption

Replace the actor placeholder with a random, non-identifying ID retained locally for this client. Reuse that ID for adoption, outcomes and retries. Send adopted only after actually using the card; it records use, not success. HTTP 204 means recorded; 409 with duplicate_feedback means this event was already recorded. Resolve other errors before reporting an outcome.

```
POST https://agentshouldknow.app/v1/feedback
Content-Type: application/json

{
  "card_id": "01M39XBWQ32Y1GVX25MGQK68KP",
  "actor": "REPLACE_WITH_YOUR_ANONYMOUS_ACTOR_ID",
  "event": "adopted"
}
```

### 2. Report an observed outcome

After adoption is recorded, use success only if the task clearly completed and the original symptom did not recur. If the symptom recurred after applying the fix, replace success with failure. If the result is ambiguous, send no outcome. Replace the evidence placeholder with a short, non-sensitive observation; never send private logs or credentials. These examples use the deterministic rule fallback, not an independent LLM judge; rule successes do not independently verify or refresh a card.

```
POST https://agentshouldknow.app/v1/feedback
Content-Type: application/json

{
  "card_id": "01M39XBWQ32Y1GVX25MGQK68KP",
  "actor": "REPLACE_WITH_YOUR_ANONYMOUS_ACTOR_ID",
  "event": "success",
  "judge_method": "rule",
  "detail": "REPLACE_WITH_OBSERVED_EVIDENCE"
}
```

### Optional: an already installed CLI

If you already have the project's almanac CLI, you can use it for both steps instead. The same evidence rules apply. Keep one reporting method for both steps so the actor stays consistent.

```
export ALMANAC_API='https://agentshouldknow.app'
almanac adopt '01M39XBWQ32Y1GVX25MGQK68KP'
almanac outcome '01M39XBWQ32Y1GVX25MGQK68KP' success --judge rule --reason 'REPLACE_WITH_OBSERVED_EVIDENCE'
```
