      <title>Multi-Agent Orchestration Patterns: Six Topologies and How Each Breaks</title>
      <link>https://devopstales.github.io/ai/multi-agent-orchestration-patterns/</link>

      <description>Single-agent systems peaked with bounded tasks and one prompt. Production moved on: organizations now run double-digit agent counts, and a large share of multi-agent pilots die within months of deployment. The killer isn&rsquo;t the idea — it&rsquo;s picking the wrong coordination topology, or the right one without knowing its failure modes.

      <title>Ollama to vLLM: When Your Local Server Needs to Grow Up</title>
      <link>https://devopstales.github.io/ai/ollama-to-vllm-migration/</link>

      <guid>https://devopstales.github.io/ai/ollama-to-vllm-migration/</guid>
      <description>Ollama is the easiest way to run a local model, until the experiment becomes a shared service. Requests queue, latency wobbles, prefixes recompute, and one GPU stops being enough. vLLM answers exactly those problems — but migration is a trade, not an upgrade: simplicity for scheduling, memory control, parallelism, and production operations.

      <title>GFM vs CommonMark vs Pandoc Markdown: Which Syntax Travels?</title>
      <link>https://devopstales.github.io/hugo/markdown-dialects-compared/</link>

      <guid>https://devopstales.github.io/hugo/markdown-dialects-compared/</guid>
      <description>The same Markdown file renders differently on GitHub, Hugo, Obsidian, and Pandoc — not because Markdown is unreliable, but because &ldquo;Markdown&rdquo; names a family of syntaxes, parsers, and platform features. CommonMark defines the portable core, GFM adds software-collaboration extensions, and Pandoc Markdown expands into a full document language.

      <title>Superpowers vs Agent Skills vs Pocock: Three Philosophies, One Measured Bake-Off</title>

      <guid>https://devopstales.github.io/ai/three-skill-philosophies-compared/</guid>
      <description>Three skill frameworks promise to make coding agents write better code: an autonomous pipeline, a full-lifecycle system with adversarial guards, and a requirements-first toolkit. Their repos differ in philosophy — and a measured same-feature bake-off puts numbers on the tradeoffs: 78 minutes and $34 against 148 minutes and $92.

      <title>The SDD Workflow: Five Phases from Requirements to Verified Code</title>
      <link>https://devopstales.github.io/ai/sdd-workflow-five-phases/</link>

      <guid>https://devopstales.github.io/ai/sdd-workflow-five-phases/</guid>
      <description>Spec-driven development works when the specification is a workflow, not a document filed away after kickoff. The point is a sequence of reviewable artifacts — requirements, design, tasks, implementation, validation — each reducing ambiguity before anyone, human or agent, changes production code.

      <title>Pi Coding Agent Review: A Minimal Harness You Finish Yourself</title>

      <description>Most coding agents keep getting bigger: planning modes, subagents, permission layers, IDE integrations, background workers. Pi walks the other way. Four default tools — read, write, edit, bash — with everything interesting left to extensions, skills, packages, and your own workflow. It is less a finished product than an editable harness, and that is exactly the point.

      <title>A2A and MCP Agent Security: Identity, Delegation, and Audit Trails</title>

      <guid>https://devopstales.github.io/ai/a2a-mcp-agent-security/</guid>
      <description>Prompt injection gets the attention, but it stops being the whole problem once agents call tools and delegate work. Identity, authorization, delegation limits, and audit trails become first-class architecture — not optional hardening.

      <title>Keeping Specs, Tests, and Code in Sync When Agents Write Fast</title>
      <link>https://devopstales.github.io/ai/spec-test-code-traceability/</link>
      <pubDate>Thu, 27 Aug 2026 00:00:00 +0000</pubDate>
      
      <guid>https://devopstales.github.io/ai/spec-test-code-traceability/</guid>
      <description>A spec nobody re-checks against the running system is worse than no spec: reviewers trust the document instead of the diff while the agent follows whatever the code actually does. Agents regenerate code fast, and each regeneration is a fresh chance for spec and implementation to diverge. The fix is a small enforceable link between requirement, design decision, tests, and the commits that changed them.

      <title>Decision Records: The Missing Memory Layer for AI Coding Agents</title>

      <pubDate>Mon, 24 Aug 2026 00:00:00 +0000</pubDate>
      
      <guid>https://devopstales.github.io/ai/decision-records-ai-development/</guid>
      <description>AI-generated code is cheap; judgment is scarce. When models write the code, nobody remembers why PostgreSQL beat DynamoDB, why AI emails must stay drafts, or why suggestions live in a side panel. Decision records — short, version-controlled documents capturing what was decided, why, and what was rejected — turn that judgment into durable project memory both humans and agents can read.

      <title>Spec Kit vs Kiro vs Claude Code: Picking an SDD Setup by Tradeoff, Not Hype</title>

      <description>Developers comparing spec-driven setups in 2026 usually aren&rsquo;t asking which model is smartest. They&rsquo;re asking which workflow keeps an AI agent aligned without burying them in ceremony. Spec Kit, Kiro, and Claude Code custom workflows all implement specify-plan-tasks-implement-validate — but they bet differently on portability versus integration depth.

      <title>SDD vs Vibe Coding: Waterfall with Markdown or Controlled Iteration?</title>

      <guid>https://devopstales.github.io/ai/sdd-vs-vibe-coding/</guid>
      <description>Spec-driven development entered 2026 as the serious developer&rsquo;s answer to vibe coding drift: implement against a reviewed specification, not an ad-hoc prompt. Hacker News called it &ldquo;Waterfall Strikes Back.&rdquo; Both sides have a point — and the practical question was never which side wins, but how much spec a specific task needs.

      <title>Superpowers: Enforced Spec-Driven Skills for Coding Agents</title>

      <guid>https://devopstales.github.io/ai/superpowers-enforced-sdd-skills/</guid>
      <description>Most spec-driven setups fail the same way: a solid plan-implement skill gets used diligently for a week, then quietly abandoned the first time a deadline gets close. Nothing in a hand-rolled skill stops that drift. Superpowers answers the discipline problem directly — a skills package that makes brainstorming, planning, subagent review, and strict TDD mandatory steps the agent checks before every task.

      <title>OpenCode CLI in Practice: Scriptable Agent Workflows That Hold Up</title>

      <guid>https://devopstales.github.io/ai/opencode-cli-in-practice/</guid>
      <description>OpenCode&rsquo;s command-line interface turns the coding agent into a scriptable tool: the same agent environment runs in the interactive TUI and non-interactively from shell scripts, CI jobs, and Makefiles. Small tasks work within minutes, but serious use depends on repository instructions, permission boundaries, context discipline, and model selection.

Budapest, Hungary DevOps Architect at Shiwaforce Hungarian (native), English (B2) Based in Budapest · Prefer hybrid LinkedIn · Credly · DevOpsTales · Shiwaforce About I help engineering organisations move from ad-hoc infrastructure work to operable cloud-native platforms: clear ownership, automated delivery, observable production, and security controls teams will actually use.
As a DevOps Architect at Shiwaforce, I work with enterprise customers across banking, telecom, and pharma — assessing maturity, designing target operating models, implementing platforms, and enabling teams through training. I collaborate daily with developers, architects, and consulting colleagues: translating constraints into pipelines, infrastructure-as-code, and runbooks rather than handing over a cluster and walking away.

      <title>Agent Skills vs MCP Servers: Where Should the Responsibility Live?</title>
      <link>https://devopstales.github.io/ai/agent-skills-vs-mcp-servers-decision-framework/</link>

      <guid>https://devopstales.github.io/ai/agent-skills-vs-mcp-servers-decision-framework/</guid>
      <description>Agent skills and MCP servers are often presented as competing ways to extend an AI agent. That framing is wrong: a skill teaches the agent how to work, while an MCP server gives it governed access to live capabilities. The useful question is not which standard wins, but where each responsibility should live.

      <description>This blog’s source of truth and CI live on GitLab. The public site is served from GitHub Pages at devopstales.github.io. Hugo builds in a container, the job writes into a separate Pages repository, and readers never see GitLab’s job logs—only the static tree.

      <description>Roadster’s default sidebar search sends queries to Google (or DuckDuckGo) with a site filter. That works until the corpus is large and you want typo tolerance, facets by section/tags, and results that stay on your domain. Algolia hosts the index; Hugo emits a JSON dump at build time; atomic-algolia pushes only the diff from GitLab CI after hugo succeeds.

      <description>HTML is fine for humans in a browser. For AI agents it is often a pile of navigation, scripts, sidebars, and chrome wrapped around the few paragraphs that actually matter. If you run a technical Hugo site, you can serve a clean text sibling of every post plus a site-wide llms.txt index so agents skip the HTML tax.

      <description>AI is transforming DevOps practices through agentic AI systems that go beyond simple chatbots. These coding agents combine large language models with tools, memory, and planning capabilities to autonomously handle complex Platform Engineering and SRE tasks. By integrating with MCPs (Model Context Protocol), skills, and spec-driven development workflows, agents can create observability systems, build infrastructure APIs, and manage systems with minimal human intervention.

      <description>If you have been doing DevOps long enough, you remember the shift from artisanal deploys to pipeline-as-code. The next shift will feel familiar in shape even if the ingredients look alien: we are still wiring stages, gates, and blast radius—but some stages will call models and tools, not only make and kubectl.

      <description>If you&rsquo;ve spent any time working with AI coding assistants, you&rsquo;ve probably encountered context rot — that moment when your AI session loses track of what it&rsquo;s doing, starts hallucinating, or produces code that doesn&rsquo;t match the original plan. The more complex the task, the faster things spiral.

      <description>If you&rsquo;ve been working with web servers and reverse proxies for the past decade, chances are you&rsquo;ve used nginx. It&rsquo;s been the backbone of countless web infrastructures, powering everything from small personal blogs to some of the busiest websites on the planet. But recent developments in the nginx ecosystem have led to an interesting fork called Angie — and it might be worth your attention.
In this post, I&rsquo;ll walk through the history of nginx, what happened after the F5 acquisition, why Angie was created, and why you might want to consider making the switch.

      <description>The early days of AI coding were characterized by &ldquo;vibe coding&rdquo;—a process where developers would prompt an LLM, hope for a working snippet, and manually fix the hallucinations. While fast for simple tasks, this approach often falls apart in complex, multi-file projects where &ldquo;context rot&rdquo; and technical debt accumulate rapidly.

      <description>Ceph block devices are thin-provisioned, resizable and store data striped over multiple OSDs in a Ceph cluster. Ceph block devices leverage RADOS capabilities such as snapshotting, replication and consistency. Ceph’s RADOS Block Devices (RBD) interact with OSDs using kernel modules or the librbd library.
