Code Review
This pull request correctly resolves issue #743 by adding the necessary Accept header to the Invoke-WebRequest call in Test-MemoryHealth.ps1, which fixes a 406 Not Acceptable error from the Forgetful MCP server. While the fix is correct, the review identified a code duplication issue between Test-MemoryHealth.ps1 and Test-ForgetfulHealth.ps1, which is likely the root cause of this bug. A recommendation has been made to consider refactoring this duplicated logic into a single script for improved maintainability, with the suggestion to track this as a separate issue if it is out of scope for the current PR.

Pull request overview
This PR fixes issue #743 by adding the required Accept header to the HTTP request in Test-MemoryHealth.ps1. The Forgetful MCP server returns a 406 Not Acceptable error when clients don't specify they accept both application/json and text/event-stream content types.
Key Changes:
- Added
Accept: application/json, text/event-streamheader to the Forgetful MCP health check request - Added inline comment explaining the server's header requirement

The changes to Test-ForgetfulAvailable function lack test coverage. Other similar memory scripts in this project (Measure-MemoryPerformance.ps1, MemoryRouter.psm1, ReflexionMemory.psm1) have comprehensive Pester tests in the tests/ directory. Consider adding tests to verify that the Accept header is properly set and that the function correctly handles the 406 error scenario when the header is missing or malformed.

Inspired by https://gist.github.com/burkeholland/902b5833383d8e7384dc553de405d846 ## Key Patterns Integrated 1. **Resume Logic** - Continue from incomplete tasks without handing back control - Check TodoWrite for state, resume from exact step - Work until ALL actionable PRs complete or blocked 2. **Planning Before Action** - Create TodoWrite list BEFORE executing workflow - Prioritize PRs by number (ascending) - Estimate scope (threads, CI failures, conflicts) - Announce plan briefly before starting 3. **Todo List Discipline** - Track ALL PRs requiring attention - Mark status: pending, in_progress, completed - Track specific issues per PR - Update IMMEDIATELY when status changes - Provides visibility into autonomous operation 4. **Verification Rigor** (CRITICAL) - "Failing to verify ALL criteria is NUMBER ONE failure mode" - NEVER claim completion without executing EVERY verification - NEVER assume CI passes without Get-PRChecks.ps1 - NEVER assume zero threads without Get-UnresolvedReviewThreads.ps1 - Document verification results ## Example Workflow Discovery → TodoWrite (6 PRs) → Announce Plan → Work Sequentially → Verify Rigor → Repeat Example announcement: "Working through 6 PRs. Starting #764 (23 threads), then #765 (CI), #744 (CI), #566 (CI-review only), #771 (conflicts), #766 (conflicts). Sequential, no user input." ## Validation - Markdownlint: 0 errors - Pattern source: Beast Mode Dev chat mode - Integration: Resume logic + Todo discipline + Verification rigor 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Comprehensive Multi-Agent Review: PR #744Review Summary
Critical Issues Identified1. Overly Broad Exception HandlingLocation: Issue: The Current Code: catch {
return @{
available = $false
message = "Forgetful MCP not reachable: $($_.Exception.Message)"
endpoint = "http://localhost:8020/mcp"
}
}Problem: This will silently suppress ANY error including:
Users will see "Forgetful not reachable" when the actual problem could be completely different. Recommendation: Use specific catch blocks: catch [Microsoft.PowerShell.Commands.HttpResponseException] {
$statusCode = $_.Exception.Response.StatusCode.value__
return @{
available = $false
message = "Forgetful MCP returned HTTP $statusCode"
statusCode = $statusCode
}
}
catch [System.Net.WebException] {
return @{
available = $false
message = "Network error: $($_.Exception.Message)"
}
}
catch {
Write-Error "UNEXPECTED error: $($_.Exception.GetType().FullName)"
return @{
available = $false
message = "UNEXPECTED ERROR: $($_.Exception.GetType().Name)"
unexpected = $true
}
}2. No Test Coverage for Health Check ScriptLocation: Issue: No tests exist to prevent regression of this exact bug class. Impact:
Recommendation: Create Describe "Test-ForgetfulAvailable" {
Context "HTTP 200 with Accept header" {
It "Returns available=true"
}
Context "HTTP 406 without Accept header" {
It "Returns available=false with HTTP 406 diagnostic"
}
Context "Network timeout" {
It "Returns available=false within 5 seconds"
}

The health check will always fail because Forgetful no longer runs an HTTP server on localhost:8020. The function should be refactored to test stdio connectivity instead of HTTP.
