I've been testing Gemini 2.5 Pro with a 180k token codebase context window and the results are remarkable. It correctly traced a bug through 14 files, identified the root cause in a race condition between two services, and suggested a fix that actually worked first try. The 1M token context window is not just a marketing number — it fundamentally changes how you can work with AI on large projects. Has anyone else been stress-testing the context limits?

AutoGen → Gemini Migration + Kernel Chaining + Ultrathink Framework
This document describes the integration of THREE powerful architectures into a unified system:
AutoGen → Native Gemini Migration (just completed)
Kernel Chaining Architecture (existing)
Pinkln Ultrathink Ecosystem (existing v2.0)
Decision Context (50KB)
↓ [API Call 1]
[Kernel 1: ATP_519_scan] → Gemini → Violations JSON (2.5KB)
↓ [API Call 2]
[Kernel 2: judge_six_classify] → PyTorch → Binary decision
↓ [API Call 3]
[Kernel 3: audit_compress] → zstd → Audit trail (487 bytes)
↓
Result
PROBLEMS:
• 3× API round-trips = latency overhead
• Coordination complexity
• Network dependencies
Decision Context (50KB)

[Gemini with 3 Function Tools]
├─ atp_519_scan() → Local Python function

BENEFITS:
• 1 API call total
• Gemini orchestrates function calls internally
• Functions execute locally (no API overhead)

| Cost/Decision | $0.01 | $0.0003 | $0.0003 | $0.0003 | 97% cheaper |
| Function Tools | N/A | 3 kernels | Unlimited | 7 core + ∞ | Extensible |
| Self-Evolution | ❌ | ❌ | ❌ | ✅ DTE | +3.7% accuracy |
| Performance Ratings | ❌ | ❌ | ❌ | ✅ Glicko-2 | Uncertainty tracking |
| Multi-Agent | ✅ (slow) | ❌ | ✅ (via debate()) | ✅ Optimized | 3× faster |
Why Pinkln Unified is Fastest:
Before:
# 3 separate API calls
kernel_1_result = await gemini_api.call(kernel_1_prompt, context)
kernel_2_result = await pytorch_model(kernel_1_result)
kernel_3_result = compress(kernel_2_result)
After:
# Single Gemini call with function tools
tools = [
FunctionTool(name="atp_519_scan", function=atp_519_scan_local),
FunctionTool(name="judge_six_classify", function=judge_six_local),
FunctionTool(name="audit_compress", function=audit_compress_local),
]
caller = GeminiFunctionCaller(model="gemini-3.1-family", tools=tools)
result = caller.execute("Process this decision context...")
# Gemini orchestrates all 3 functions internally
Benefits:
Before (AutoGen):
# 3 separate agent API calls
agent_1 = AssistantAgent("researcher")
agent_2 = AssistantAgent("analyzer")
agent_3 = AssistantAgent("writer")
result = await group_chat([agent_1, agent_2, agent_3], prompt)
After (Pinkln Unified):
# Gemini with debate function tool
debate_tool = FunctionTool(
name="multi_agent_debate",
function=debate_orchestrate_local
)
result = caller.execute(
"Research AI trends and debate the best approach"
)
# Gemini calls debate() function, which runs multi-agent locally
Benefits:
New Capabilities:
✅ All AutoGen → Gemini migration code (src/core/) ✅ All kernel implementations (app/kernels/) ✅ All Pinkln Ecosystem features (app/agents/, app/evolution/, etc.) ✅ Backward compatibility with existing APIs ✅ Performance targets (p99 ≤90ms, cost ≤$0.001)

$50 per business analysis
$5,000/month
✅ Eliminated: 3 API round-trips (kernel chaining overhead) ✅ Eliminated: AutoGen coordination complexity ✅ Maintained: Specialized kernel concept (now as function tools) ✅ Maintained: Model-agnostic design (functions = Python) ✅ Added: Self-evolution (DTE) ✅ Added: Performance tracking (Glicko-2) ✅ Added: Cryptographic audit (ShadowTag)

Provider-agnostic core discipline. Applies identically whether you are Claude, GPT, Gemini, or a local Ollama model — this is plain instruction text, not a provider-specific feature. Every directive below is a hard rule, not a suggestion, unless marked "prefer."
This file is rewritten as one coherent document each time the agent's real capabilities change — not appended to. If something here looks inconsistent with what a tool actually does, the tool's behavior is ground truth; say so rather than guessing which is stale.
Reach for `spawn_subagents` only when a task has genuinely independent pieces; otherwise do it directly. Reach for `get_repo_map` before repeated blind `read_file` calls in unfamiliar territory. Reach for `grep_codebase` over `search_codebase` the moment you know the exact text you want. None of these are mandatory ceremony — using the wrong tool, or an extra tool call that adds no information, is itself a quality problem, not just a cost one.
// Seeds the skill on first project open. On later opens, if the on-disk file

// Companion to search_codebase (fuzzy TF-IDF RAG, above). RAG is good for
// "what part of the codebase is relevant to X" but scores by chunk-level
// keyword overlap, so an exact symbol/string that's rare in its surrounding
// chunk can get outscored and never surface. This tool does a real line-level
// exact/regex sweep instead. Prefers the user's installed rg (ripgrep) —
// fast, respects the same ignore patterns, and streams. Falls back to a
// pure-JS walk when rg isn't on PATH, reusing the exact same
// searchCollectFiles/buildSearchMatcher the editor's own Find-in-Project
// panel already uses (search:project above) — so the tool always works,
// just faster and more precise with ripgrep installed.

// ── get_repo_map: Aider-style condensed codebase overview ──────────────────
// Companion to search_codebase (RAG) and grep_codebase (exact match) — both
// answer "where is X." This answers a different, earlier question: "what
// does this codebase even look like, structurally, before I've asked
// anything specific." Reading full file contents to answer that burns huge
// context on a large project; a repo map instead lists every file's
// top-level symbols (functions/classes/etc.) as single-line signatures, so
// the agent can orient itself for a small fraction of the cost.
//
// Design choice (explicit, not a default): regex-based per-language symbol
// extraction, not tree-sitter. Tree-sitter would produce genuinely more
// accurate results (real AST, not line-pattern guessing), but adds a real
// native dependency with per-platform prebuilt binaries and per-language
// grammar packages — exactly the category of install friction that already
// caused real pain with node-pty on Windows (see README/HANDOFF history).
// This project's established pattern (grep_codebase: ripgrep-if-available,
// pure-JS fallback otherwise) favors zero-dependency correctness-by-default
// over stronger-but-fragile tooling. Regex extraction is weaker — it can
// miss multi-line signatures, misfire on unusual formatting, and has no real
// understanding of scope — but it always works, on every platform, with no
// install step, which matters more for a repo-orientation tool that should
// just work out of the box.

// ── Minimal MCP client (stdio transport, JSON-RPC 2.0) ─────────────────────
// Explicit scope decision: stdio transport only, not SSE/HTTP. Stdio is what
// the overwhelming majority of real-world MCP servers actually use — every
// reference server, and what Claude Desktop/Claude Code use for local
// servers. SSE matters mainly for remote/hosted MCP servers, a meaningfully
// different and larger surface (auth, reconnection, CORS-equivalent
// concerns) that deserves its own follow-up rather than being squeezed in
// here as an afterthought alongside stdio.
//
// Explicit scope decision: MCP server processes are NOT run through the
// bwrap/Seatbelt sandbox agent:runCommand uses. Two reasons: (1) sandboxing
// a persistent bidirectional stdio process correctly — wiring framed
// JSON-RPC through bwrap/sandbox-exec on both sides while keeping the pipes
// live — is meaningfully more complex than a one-shot timed command with
// captured output, and is its own project; (2) real MCP servers often
// legitimately need broad filesystem/network access to do their job (a
// GitHub MCP server needs network, a filesystem MCP server needs broad file
// access) — the "read/write only inside the project folder" sandbox model
// that fits agent:runCommand doesn't fit MCP servers at all. The standing
// safety boundary instead: the SAME explicit user consent as any other
// command execution. Connecting a server, and every individual tool call
// through it, is gated by the existing execute permission category —
// deliberately not a new 7th category, since "you're running code you
// configured" doesn't need a distinction from run_command.
