Agent Team v2: Self-Improving Closed Loop, Performance Optimization & Deploy Pipeline

[LeftTwixWand]

Summary

Agent team redesign with performance optimization. 88% token reduction for simple tasks via direct agent routing that bypasses CodeOrchestrator.

Agent Team Redesign

• SendToAgent fast path — Thread routes directly to agents, no more AgentSelector + CodeOrchestrator for simple tasks
• DotNet owns all .NET operations — build, run, test, publish with auto-discovery of .csproj/.sln
• Shell scoped to raw CLI only — npm, pip, cargo, scripts
• Aspire agent — typed tools for restart, traces, logs, health (keeps MCP for observability)
• Engineered [Description] attributes on all 15+ interface methods
• Three-layer instructions (Identity → Rules → Reference) for all agents
• Workspace restriction removed — full PC access
• Model tier optimization — FileSystem/Git on Fast (Nano), DotNet on Sonnet, Shell on Haiku

Performance Optimization

• 4KB result truncation in SendToAgent (prevents Thread context bloat)
• 8KB output truncation in GetResponse (prevents all agent context bloat)
• Actionable error messages with agent-specific recovery suggestions
• Non-LLM pre-filters for deterministic build errors in CodeOrchestrator
• Filter LLM wrapper agents from AgentSelector candidates
• Filter orchestrator catalog to selected agents only

Bug Fixes

• RunDotnetAsync 120s timeout — GUI apps no longer block forever
• GetResponseStream [ResponseTimeout] — streaming methods now have 5-min timeout
• StreamResponseCore cancellation — clean handling, not counted as errors
• Per-provider 10s timeout in BuildContextBlock
• Telegram webhook — 5-min CancellationTokenSource instead of CancellationToken.None

Self-Improvement Foundation (partial — deploy via Aspire SDK planned separately)

• SelfImprove tool — Thread coordinates agents to read code, analyze, write fixes, build
• Aspire log monitor — recurring 30-min health check via DurableJobs
• Deploy capability is a TODO — will use Aspire SDK WithCommand("deploy") + ResourceCommandService

Performance Impact

Metric	Before	After
Simple task tokens	~21K+	~3-5K
Simple task time	2+ min	5-20s
Models for simple tasks	Opus 4.6	gpt-5.4-mini + nano
CodeOrchestrator for builds	Always	Never (direct routing)
Stuck on GUI apps	Forever	120s timeout + kill

Test plan

• dotnet build IAW.slnx — 0 errors
• dotnet test test/Core.Tests — 409 passed (2 pre-existing failures)
• Simple task routing verified via Aspire traces (DotNet build, File read, Git status, Aspire health)
• Token usage verified: <5K tokens for simple tasks vs 21K+ before
• No AgentSelector or CodeOrchestrator involvement in simple tasks

Code review

Found 3 issues:

1. TryDeterministicFix returns "add_using_system" but the retry loop only handles "skip" and "retry" -- the action is dead code that falls through to the LLM retry path without applying any fix

IAW/src/Agents/Orchestration/CodeOrchestratorAgent.cs

Lines 542 to 557 in f00dedd

	static string? TryDeterministicFix(string buildOutput)
	{
	if (buildOutput.Contains("CS0246") && buildOutput.Contains("IAW.Agents"))
	return "skip";
	if (buildOutput.Contains("CS0103") && buildOutput.Contains("'Console'"))
	return "add_using_system";
	if (buildOutput.Contains("The process cannot access the file"))
	return "skip";
	if (buildOutput.Contains("timed out"))
	return "retry";
	return null;
	}

2. DotNetAgent.RunAsync reads stdout then stderr sequentially via ReadToEndAsync. If the child process fills the stderr pipe buffer while the parent drains stdout, both deadlock until the 120s timeout fires. Should use Task.WhenAll to read both concurrently.

IAW/src/Agents.CSharp/DotNet/DotNetAgent.cs

Lines 112 to 118 in f00dedd

	try
	{
	var output = await process.StandardOutput.ReadToEndAsync(timeoutCts.Token);
	var error = await process.StandardError.ReadToEndAsync(timeoutCts.Token);
	await process.WaitForExitAsync(timeoutCts.Token);
	sw.Stop();

3. SelfImproveAsync hardcodes E:\IAW as the source path. This is machine-specific and will break in CI or on other developer machines. Should use an environment variable or resolve from AppContext.BaseDirectory.

IAW/src/Agents/Orchestration/ThreadAgent.cs

Lines 114 to 117 in f00dedd

	You must accomplish this by calling SendToAgent multiple times. The IAW source code is at E:\IAW.
	Available agents: FileSystem (read/write files), DotNet (build/test), Git (commit), Aspire (restart to deploy), Roslyn (analyze code).
