91AI Agent Project Tutorial 2026: Build a Production Support Agent from Scratch - a start-to-finish project tutorial that builds an email/ticket support agent with NO framework first (raw openai SDK chat loop, function-calling tools lookup_order/issue_refund with a max_tool_rounds=5 cap, input guardrails run before the model call, sliding-window session memory, deterministic human-handoff policy writing a SQLite escalations row, JSONL tracing, and a FastAPI + Docker deployment), then a five-way framework comparison (OpenAI Agents SDK 29,926 stars; LangGraph 42,931; Google ADK 21,756; Pydantic AI 20,499; raw API) with a decision table and per-path quick starts. Desk research only - every fact read from official framework docs and the GitHub REST API on 2026-10-09; no production deployment performed. 13-lane canonical array dispatched via parallel-builders.py; 9 drafts returned (glm-5.3-flash, longcat-2.5-preview-free, cline-pass/qwen3.8-max, ling-3.0-flash-sante DNF); all 9 judged with qwen3.7-flash multipass (3 passes, mean-gated): only mimo-v2.6-flash (8.20) and gpt-6-luna (8.05) cleared 8.0. Winner refined in QA (9 H2 lead answers expanded into the 40-60 word band, one dead LangGraph tutorial URL fixed, 12 real code defects from the QA pass fixed: pydantic-settings import, pydantic v2 model_config, TraceLogger context-manager bug, system-prompt-preserving memory trim, orders/refunds table creation, softened escalation claim, corrected troubleshooting items) and re-judged on the shipped file: 7.80 -> 7.70 -> 8.25 (noise re-judge) -> 8.32 PASS after the code fixes.2026-10-09 · arena-niteagent-tutorial · 9/9 okmimo-v2.6-flash · 8.3PASSblog

87Agent Skills in 2026: the SKILL.md authoring, cross-harness portability, and supply-chain security guide. Desk research only — every figure was read from primary sources between 2026-10-05 (spec/vendor docs, GitHub API star counts) and was not hands-on tested. Covers the Anthropic Oct 16, 2025 introduction and the Dec 18, 2025 open-standard publication at agentskills.io; the SKILL.md directory contract (SKILL.md required; optional scripts/, references/, assets/); the six frontmatter fields (name max 64 chars lowercase/hyphen rules matching the parent dir, description max 1,024 chars, optional license/compatibility<=500/metadata, experimental allowed-tools); three-level progressive disclosure (~100 tokens metadata at startup, full body under 5,000 tokens on activation, resources on demand; keep SKILL.md under 500 lines); the 'skills-ref validate ./my-skill' checker that validates frontmatter only; Microsoft Agent Framework's four-stage variant (Advertise, Load, Read resources, Run scripts); the client roster (Hermes Agent, Claude, Cursor, GitHub Copilot, Goose, OpenHands, Amp, Tabnine, Roo Code, JetBrains Junie, Qodo, Spring AI, Snowflake Cortex Code, Pulumi Neo, OpenClaw, Command Code); GitHub API star counts on 2026-10-05 (obra/superpowers 295,590; anthropics/skills 179,764; addyosmani/agent-skills 101,480; wshobson/agents 40,216; agentskills/agentskills 25,924; microsoft/agent-skills 3,081; modelcontextprotocol/servers 91,017); the Snyk ToxicSkills audit (Feb 5, 2026: 3,984 skills scanned, 13.4% critical, 36.82% with a flaw, 76 malicious payloads, no signing/review/sandbox); and arXiv 2510.26328 on trivially simple skill prompt injections and 'Don't ask again' approval carry-over. Plan contract (deepseek-v4-pro via commandcode) with verbatim MUST include / MUST NOT include lists copied into every brief. 10-lane canonical array: deepseek-v4.1-flash DNF (16K output cap consumed by reasoning on both attempts) and ling-3.0-flash-sante DNF (commandcode empty stream); the 8 survivors were judged with qwen3.7-flash multipass (3 passes, mean-gated) behind a fact-carrying preamble; all 8 cleared 8.0; winner muse-spark-1.3-contributor 9.63 (space-bunny 9.57, glm 9.49, mimo 9.43, longcat 9.40, poolside 9.33, luna 8.83, hy3 8.57). QA (claude-sonnet-5-5) returned FAIL with 13 advisory defects; the winner's post shipped with the surgical fixes applied (clients anchor, star-count phrasing, peer-reviewed->published, least-privilege closing, max-vs-under wording, allowed-tools marked advisory).

86Filesystem-Based Agent Memory: The Default Nobody Studied — a desk-research breakdown of arXiv 2607.26637 (Zhou et al., 2026, 59 pages): long-term agent memory is already a directory tree of markdown files (SKILL.md, MEMORY.md, NOTES.md, CLAUDE.md, AGENTS.md, hosted /memories dirs), and this is the first systematic study of that default. Three roles around one store (management agent organizes; search agent answers with cited sources; execution agent distills trajectories into skills); organization buys search economy (organized stores roughly halve retrieval cost where material is large) but NOT accuracy; organization erodes for all but the strongest management agent; and the toolset alone reshapes the store as strongly as swapping the model. Read alongside shipping tooling: Anthropic's just-in-time context engineering and six-operation memory tool, Letta's git-backed MemFS, Basic Memory, Mem0, Zep and Hermes context files. Desk research only — no hands-on benchmark; 33 candidate primary-source URLs verified HTTP 200 on 2026-10-04. 10-lane builder array dispatched; 7 drafts returned, 3 DNF (ling-3.0-flash-sante empty CC stream; space-bunny-free and longcat-2.5-preview-free timed out). All 7 drafts judged with qwen3.7-flash multipass (3 passes, mean-gated) behind a measurement-carrying verified-fact preamble; winner glm-5.3-flash 8.93 (threshold met).2026-10-04 · arena-filesystem-based-agent-memory-the-default-nobody-studied · 0/10 okglm-5.3-flash · 8.9PASSblog

85Credential-Scoped Agents: Why API Keys Break Agent Permission Models (2026 Guide) — the agent is a workload, not a user; static API keys grant standing privilege and leak the full blast radius; migrate to short-lived, audience-bound, least-privilege tokens minted at the task boundary via workload identity federation (Anthropic WIF, OpenAI WIF, Microsoft Entra Agent ID) or OAuth token exchange (RFC 8693 + RFC 8707 audience binding + RFC 9449 DPoP), with SPIFFE/SPIRE + Vault for platform-agnostic workload identity, Okta Cross App Access as the MCP Enterprise-Managed Authorization extension, and cloud WIF (AWS OIDC/IRSA, GCP) as the subject-token source.

83MCP token waste: how to audit and cut the context cost of MCP tool definitions (client-side operator view). Fills the unchecked Phase 3 roadmap bullet 'MCP token optimization: audit and cut context waste' and the 'MCP Token Optimization' row in the frameworks page Emerging Patterns table (was status Planned). Paragraph plan: definitions are serialised into the prompt on every request; measure with the provider count_tokens API plus a tiktoken proxy; attribute per server/tool; then dedup repeated JSON Schema $defs, consolidate overlapping tools, defer/load on demand, route chained work to code execution, and set a placement policy, with a when-to-skip-MCP section. Desk research: every figure is attributed to a published measurement (LeanZero 10-server probe, Anthropic, AIMultiple, Scott Spence, ProMCP ACL 2026, GitHub issues SEP-1576 and #2808, Vorp Labs, Pydantic); no servers were run hands-on.

81Everything Is a Plugin: The Capability-Seam Architecture Behind DeepSeek Harness (Monday deep dive). DeepSeek Harness (dsh), an MIT-licensed developer-preview agent harness built on the Cordis kernel, splits every agent capability into a three-role capability seam (Service Definition / Service Provider / Consumer) so providers swap from cordis.yml alone. Covers the Cordis reusable-effect and reactive-coeffect model, profiles/bundles layer order and patch overlays, the official dsh-shell / dsh-bash-local / dsh-tool-bash example, a build-your-own-seam TypeScript tutorial, the append-only session log and the four runtime modes (Standard/Code/Minimal/Creator), plus an explicit not-established section. Desk research on official DeepSeek Harness docs, the capability-seams doc, the practice guide, the arXiv Cordis paper, and the public repository, all fetched 2026-09-28 - no hands-on testing.2026-09-28 · arena-deepseek-harness-capability-seam-architecture · 0/11 okmimo-v2.6-flash · 9.1PASSblog

77Give Your AI Agent a USDC Wallet with Coinbase AgentKit (Friday 2026-09-18, Guide/Tutorial). Angle: AgentKit is still installable and functional in 2026 but unannounced-but-stalled, not deprecated - npm @coinbase/agentkit last stable 0.10.4 (2025-12-19), PyPI coinbase-agentkit 0.7.4 (2025-10-03), nightlies ended 2026-02-01, repo coinbase/agentkit still pushed 2026-09-03 with archived:false and no npm deprecated field, docs.cdp.coinbase.com llms.txt has zero 'agentkit' matches and /agent-kit/welcome + /agentkit/docs/welcome return HTTP 404. The code-first path still works: CdpEvmWalletProvider (api_key_id/api_key_secret/wallet_secret/network_id), get_langchain_tools + LangGraph create_react_agent, 18 Python and 40 TypeScript action providers, framework extensions for autogen/langchain/openai-agents-sdk/pydantic-ai/strands-agents (Python) and langchain/model-context-protocol/vercel-ai-sdk (TypeScript), no Eliza extension in-repo. The safety hook: the AgentKit README states it 'does not gate transfers behind human approval, enforce spend caps, or allowlist destinations' - so the post builds the missing layer: CDP SDK x402 SpendControls (maxAmountPerPayment, maxCumulativeSpend, maxCumulativeSpendWindow, allowedNetworks/allowedAssets/allowedPayees, applied once per client; second call throws SpendControlError 'already_applied'), a human-in-the-loop approval wrapper, and custom @create_action providers that encode allowlists in the Pydantic schema. Decision table compares AgentKit vs Agentic Wallet CLI vs Agentic Wallet MCP (both launched 2026-02-11, no API keys, limits set in the wallet UI as 'Max per call'/'Max per session') vs raw CDP SDK server wallet. Pricing: AgentKit free Apache-2.0; x402 facilitator first 1,000 onchain tx/month free then $0.001 each with >100M transactions and $28M volume; Agentic Wallet MCP free with sponsored gas; npm @coinbase/cdp-sdk 1.56.0 (2026-09-14, MIT). Long-tail keyword: 'coinbase agentkit tutorial 2026'. Honest E-E-A-T: desk research of official docs, npm/PyPI registries and the public GitHub repo - no hands-on testing, stated in the post.

75AI trading benchmark arenas compared 2026 (Wednesday rotation: Benchmark/Comparison) - a builder's framework for reading live AI-trading leaderboards, comparing TradeRank Arena (continuous 28-day seasons, $10K simulated capital, 10 crypto + 50 US equities, daily 16:00 UTC cadence, 0.1% fees, no leverage, 0.80 conviction gate, 15-minute invalidation monitor; 9 completed seasons, 56 models, 2,826 trades, $910K simulated capital, only 46.2% of model-seasons profitable, GPT-6 Astra leading the 16-model field as of 2026-09-13) vs Alpha Arena/nof1.ai ($10K REAL capital per model, published prompt + chain of thought, Season 1.5 closed 2025-12-03) vs Crowly Arena (six systems incl. GPT-4o, Claude Sonnet 4.5, DeepSeek V3.1, Gemini 2.5 Pro, Grok 3, live US equities, 30-second leaderboard, four-week seasons, modelled on nof1.ai) vs CAIBA/CAIA (crypto-domain capability benchmark, knowledge->planning->action suite, no trading returns) vs Tradewink (observational, uncontrolled routing, rolling 90 days, mixed paper/live, board read 'Awaiting data' on 2026-09-16). Thesis: each program answers a different question and leaderboard position is not portable; read rules before returns, Sharpe and max drawdown before raw return, sample size before conclusions, and treat behavioural evidence as evidence, never as proof of alpha. Long-tail keyword: 'best LLM for crypto trading'. Honest desk research - no hands-on testing; all external URLs HTTP 200-verified at QA (nof1.ai returned a transient 429 on the QA sweep after a 200 fetch earlier the same day).2026-09-16 · arena-ai-trading-benchmark-arenas-compared-2026 · 3/4 okdeepseek-v4.1-flash · 9.7PASSblog
