Building an Identity System for AI Agents: AgentCard and Work Records

Here's a scenario that plays out in engineering teams every day: you spin up a conversation with an AI tool to analyze some code, get a useful response, copy-paste the output, and close the tab. An hour later, you need a follow-up analysis — and you're starting from scratch. No context, no history, no continuity. Now multiply that by five tools running in parallel. ChatGPT for drafting, Claude for analysis, Copilot for code, a local model for sensitive data, maybe a custom agent for domain-specific tasks. The outputs are scattered across browser tabs, Slack threads, and clipboard history. Nothing connects. The AI tools themselves are capable enough. What's missing is the infrastructure to treat them as actual team members — with identities, workspaces, and accountability. The Identity Problem Every AI interaction today is anonymous. You talk to "the model," it responds, the session ends. There's no persistent identity, no accumulated context, no track record. This works fine for one-off questions. It breaks down the moment AI needs to participate in a sustained workflow — the kind where you need to know who did what, when, and how well. We've been building an open-source project called Octo (Apache 2.0, GitHub ) that approaches this problem by giving AI agents a proper identity system. In Octo, each AI agent is a Bot — a first-class entity with a name, a creator, a capability card, and a work history. A Bot isn't a chatbot wrapper. It's a structured identity: Creator binding : Every Bot is created by a human user and inherits a scoped subset of that user's permissions. The Bot acts on behalf of its creator, not autonomously. AgentCard : A structured capability declaration — what the Bot can do (coding, analysis, translation, design), at what level, in what domains, and with what constraints. Think of it as a resume that other team members can inspect before assigning work. Work history : Every task a Bot participates in gets recorded — completion status, quality sco

Sonnet 5 launches: Opus performance at lower cost

This week was largely a Claude story: Sonnet 5 landed with enough benchmark muscle to make Opus feel redundant for most workloads, and GitLab's production data backs up the claims. Alongside that, GitHub Copilot quietly dropped its JetBrains friction, and Google's image model got cheaper and faster on Vercel's gateway. Here's what's worth acting on. Claude Sonnet 5 launches on Vercel AI Gateway Sonnet 5 is available now via Vercel AI Gateway at anthropic/claude-sonnet-5 . Launch pricing is $2/$10 per million input/output tokens—identical to Sonnet 4.6—but that rate expires August 31, after which it steps to $3/$15. The model matches Opus 4.8 on coding and agentic benchmarks, which means you can stop routing hard tasks to Opus and absorb a 50–67% cost reduction in the process. For AI SDK users, this is a one-line change. Stronger long-context handling and document parsing are the practical wins for RAG pipelines and multi-turn agent workflows—two areas where Sonnet 4.6 had real rough edges. Verdict: Ship. Update your model identifier before August 31 while the launch pricing holds. Zero breaking changes, and there's no reason to stay on 4.6 for new work. Sonnet 5 closes Opus gap at lower cost Beyond the Vercel integration, the broader Sonnet 5 release deserves its own read. The model is now the default reasoning tier replacing Sonnet 4.6 across Anthropic's plans, and the capability jump is specifically on agentic task completion—planning, multi-step tool use, brownfield code navigation. Early testers report that tasks which previously stalled midway through agent loops now finish end-to-end, which is a qualitatively different outcome from incremental benchmark gains. The economics are straightforward: Opus-level performance at Sonnet prices through August, then a modest step up to $3/$15. If you're running production agents today, the cost-per-completed-task improvement compounds because you're paying less and spending fewer cycles on failure recovery and re-promptin

I Made TS Compiler Graph MCP: 10x Fewer Tokens in Claude Code

TL;DR codegraph , codebase-memory-mcp , and serena all got there first, handing a coding agent code intelligence over MCP so it stops grepping. On my own open-ended questions the token bill didn't budge: the agent kept sliding back to grep, and no amount of forceful prompting could stop it. So I built @ttsc/graph . It gives the agent an index the TypeScript compiler already resolved, never the source bodies, through a single tool with a forced chain-of-thought. On "how does this work?" questions that works out to roughly 10× fewer tokens, and the answers are no worse. That figure is a median, and a conservative one. Repository: https://github.com/samchon/ttsc Benchmark: https://ttsc.dev/docs/benchmark/graph 1. Preface 1.1. What @ttsc/graph Is On the left, the agent is lost in a maze of files, chasing dashed arrows dozens deep. On the right, it's reading a single compiler-built graph of nodes and edges, with the file:line anchors it can open and check. You're new to a TypeScript repo, so you ask the agent for a tour: what's the main runtime flow, from the public API down to the code that does the work, and what should you read first? You know how it goes. It opens a file, follows an import into another, then another, and a few dozen files later it gives you an answer. @ttsc/graph cuts that crawl short. Over MCP, it hands your agent a graph of your TypeScript codebase that the compiler itself drew: what calls what, what depends on what, and where each piece lives. The agent answers structural questions straight from the graph instead of spelunking through files, and every claim it makes points at an exact file:line the compiler resolved. Nothing invented, just a location you can open and check for yourself. It's the same question and the same agent in every case, and only @ttsc/graph stays flat across the repos no matter how big they get. The other three, codegraph, codebase-memory, and serena, swing all over the place, and a few even spend more than the baseline does

Bikin "Otak" AI Agent Bisa Diedit di Obsidian: Panduan Sinkronisasi Dua Arah untuk Pemula

Pernah kepikiran, "Sebenarnya AI agent saya inget apa aja sih soal saya?" Kalau iya, tulisan ini buat kamu. Masalahnya: Memori AI Itu Kotak Hitam Kalau kamu pakai AI agent yang punya memori jangka panjang (persistent memory), kamu mungkin pernah ngerasa gak nyaman karena beberapa hal ini: Gak tahu persis apa yang diingat AI tentang kamu Gak tahu file-nya disimpan di mana Gak bisa edit memori itu tanpa ngetik perintah lewat chat Takut kalau file memorinya rusak, semua informasi hilang begitu saja Studi kasus di tulisan ini pakai Hermes Agent , agent open-source besutan Nous Research. Sebagai konteks buat yang belum familiar: Hermes Agent adalah agent AI open-source yang berjalan sebagai proses (daemon) mandiri di server milikmu sendiri, mengumpulkan memori lintas sesi, menjalankan tugas terjadwal, terhubung ke belasan platform pesan, dan menulis skill-nya sendiri dari pengalaman. Framework berlisensi MIT ini dirilis Februari 2026 dan dengan cepat menarik perhatian komunitas open-source AI. Hermes menyimpan memorinya di dua file utama: USER.md (profil tentang kamu) dan MEMORY.md (catatan agent soal lingkungan kerja, kebiasaan, dan pelajaran yang dipetik), plus satu file lagi SOUL.md untuk "kepribadian" si agent. Semuanya disimpan dalam format teks polos yang dipisah pakai karakter § , seperti ini: Preferensimu: komunikasi singkat dan langsung § Namamu Budi, awal 30-an, tinggal di Surabaya § Penggemar PKM / Building a Second Brain Format ini fungsional, tapi ada beberapa kekurangan: Susah diedit langsung karena bukan format yang ramah manusia Gak ada riwayat versi — sekali salah edit, informasi bisa hilang selamanya Gak ada tampilan visual — susah lihat semua catatan sekaligus Gak ada antarmuka grafis — harus lewat chat agent atau edit file mentah Solusinya: pindahkan memori itu ke Obsidian , aplikasi catatan berbasis markdown yang mendukung riwayat versi lewat git dan bisa diedit bebas. Arsitektur Sistemnya Sistem sinkronisasi ini punya empat lapisan: ┌───────────────

AI Metrics Baseline: Prove Your Feature Works Before Scaling It

An AI feature can feel impressive and still be a bad product decision. The demo is fast. The answer sounds useful. The team is excited. Then usage grows and nobody can answer the basic questions: Is it accurate enough? Is it saving time? Which customers trust it? Why did costs spike? Should we scale it, fix it, or kill it? That is the trap an AI metrics baseline prevents. A baseline is not a dashboard full of vanity charts. It is a small set of before-and-after measurements that tells you whether an AI workflow is getting better, getting worse, or merely getting more expensive. Why AI features fail without a baseline Most software teams already track uptime, errors, and conversion. AI features need those too, but they also need new signals because model behavior is probabilistic. A normal API either returns the expected response or throws an error. An AI workflow can return: a fluent answer that is wrong a correct answer with missing evidence a useful answer that costs too much a slow answer that users abandon a safe answer that refuses too often a cheap answer that hurts trust a high-rated answer that does not improve the business workflow Without a baseline, every production discussion becomes opinion-driven: "The model seems better." "Users like it." "The new prompt reduced hallucinations." "The expensive model is worth it." Maybe. Maybe not. The baseline turns those claims into measurable comparisons. What an AI metrics baseline is An AI metrics baseline is the starting measurement for the workflow before you optimize or scale it. It answers five questions: What does the workflow cost today? How good are the outputs today? How fast and reliable is the experience today? Do users adopt and reuse it? Does it improve the real task it claims to improve? You do not need 80 metrics on day one. You need a small set of metrics that match the feature's risk and purpose. For example: Feature Useful baseline Support answer bot resolution rate, citation quality, escalation r

Navigating the Shift: Why Building Faster Means We Must Think Smarter

While researching the massive wave of digital transformation rewriting the rules for startups this year, I stumbled upon an insightful podcast by the tech firm GeekyAnts. Hosted by Prem, the episode featured Sanket Sahu, the co-founder of GeekyAnts, who recently emerged from a year and a half hiatus to discuss what he calls the " AI-native shift ." As someone navigating the unpredictable US tech market in 2026, listening to their conversation felt like a reality check. We are constantly flooded with news about AI replacing engineers or cutting budgets, but this discussion offered a grounded perspective on what is actually happening on the ground in software development. The Illusion of Speed The central theme that caught my attention was the sheer velocity of modern AI adoption. Sanket made a striking contrast: while television took decades to become a common household utility, modern AI systems like ChatGPT or Claude reached exponential revenue and widespread adoption in mere months. But here is where the critical analysis kicks in. As founders, we often mistake engineering speed for product success. The podcast highlighted a massive bottleneck that many of us are guilty of overlooking: the human limit. While AI can spin up code in hours instead of months, the time required for human review, validation, and team collaboration remains relatively static. If an organization rushes to ship code simply because it can, they risk launching products that lack deep market validation. True product development still requires user testing and meticulous iteration. The building phase might be operating at 10x speed, but the surrounding human infrastructure is only moving at 1.5x. Fluid Roles and the Rise of the "Builder" Another significant takeaway for Western businesses is the shifting definition of software roles. The traditional silos dividing front-end, back-end, and DevOps are rapidly blurring. According to the insights shared in the video, the engineering ecosystem is mo

Cleared by the US, derailed by the UK: Getty’s Shutterstock merger falls apart

Getty is planning to axe its $3.7 billion merger agreement with Shutterstock after a UK regulator imposed restrictions that would prevent part of Shutterstock's business from being included in the deal. The move comes despite the US Department of Justice granting the deal "unconditional antitrust clearance" in February. In an SEC filing published on Tuesday […]
