Semaphore Uncut: Recent Episodes
Semaphore CI
In this podcast, Semaphore’s co-founder Darko Fabijan discusses the themes surrounding impact-driven software, and how we can support a culture of innovation in the world’s leading software companies.Building greater software, for global impact.
Flaky test data is now accessible through the sem-ai API, and this week also brings a skill that uses that data to fix the tests automatically.
Flaky test data is now generally available through the API. You can query your flakiest tests programmatically, sorted by number of disruptions, with failure timestamps and logs included. Find it on github.
A new sem-ai skill can identify and fix flaky tests end-to-end. The agent pulls the highest-disruption tests, gathers failure context, determines the root cause, and writes a fix. It then verifies the result, first by running tests locally, and if that’s not possible, by spinning up Semaphore test boxes to run the test across multiple machines in parallel. Running the test repeatedly across machines is especially important for flaky tests, since a single passing run isn’t enough to confirm a fix. Benchmarking on a real open source project with Claude Opus on high effort showed a cost of $1 to $1.50 per fix.
Four existing skills were improved with additional examples. Agents were occasionally not following skill instructions due to a lack of examples. Adding concrete examples improves adherence and makes sem-ai’s output more consistent across runs.
What’s Coming
User and organization management will be added to the API in an upcoming release. The team is also continuing to refine skills and commands based on usage patterns.

Here’s an update on what our engineering team has been shipping in sem-ai and what’s coming up next.
Codex marketplace support is live.A few issues were blocking some users from getting sem-ai working on Codex. Those are now fixed. If you tried it before and hit a wall, it’s worth giving it another shot.
Task creation got faster.We cleaned up some unnecessary API calls that were causing hiccups. You can now create and manage tasks on your projects entirely through the CLI, exactly where your agent already lives.
sem-ai plugin submitted to the Claude marketplace.We’re in review. We’ll share more once it’s through.
On the horizon:The team is working on full platform management through sem-ai. Members, organizations, and everything else currently in the Semaphore UI will be accessible directly through the CLI.
Also shipped: Show/hide skipped blocks in the workflow editor is now generally available. If you work with complex pipelines, it makes reading results a lot cleaner.

We’ve been talking a lot recently about AI-native developer workflows and where CICD is heading. This week, we shared one of our most exciting demos yet: a look at how SEMai is changing the way developers interact with CICD systems.
In the demo, Marcos starts with a completely clean repository: no CI configuration, no GitHub Actions workflows, nothing.
Then, inside Claude Code, he runs a single command:
/sem-ai init
From there, sem-ai analyzes the repository, detects the tech stack, and generates a tailored CICD pipeline automatically.
It recommends:
-
Linting
-
Security scanning
-
Matrix testing
-
Pipeline topology improvements
But the most interesting part comes afterward.
Marcos tells the agent:
“Work until the pipeline is green.”
The system monitors the pipeline, analyzes failures, applies fixes, reruns workflows, and eventually gets the build passing successfully while summarizing everything it changed along the way.
Nick also shares lessons learned while building the onboarding experience itself, including why slash commands became critical for reliable agent workflows and how improving contextual skills dramatically increased success rates.
This is what we mean when we talk about AI-native CICD:not AI bolted onto existing tooling, but a fundamentally different developer experience built around collaboration between developers and agents.
In the full demo, Marko, Marcos, and Nick walk through:
-
AI-assisted CICD onboarding
-
Slash command workflows
-
Self-healing pipelines
-
Pipeline optimization
-
The evolution of SEMai skills and agent context
We’re excited about where this is heading and look forward to sharing more soon.

Developers are increasingly working inside AI-powered coding tools like Claude Code, Cursor, and Codex.
The workflow is changing.
Instead of constantly switching between dashboards, logs, terminals, and configuration files, developers are starting to collaborate directly with coding agents using natural language.
We think CI/CD should evolve alongside that shift.
Today, we’re introducing Semaphore for AI Agents — a new open-source CLI and agentic interface designed to make Semaphore fully accessible from AI coding agents.
This is the first step toward what we call the AI-native Semaphore experience.
What is Semaphore for AI Agents?
Semaphore for AI Agents gives coding assistants a structured way to interact with Semaphore.
Instead of manually navigating CI/CD systems, developers can simply ask:
-
“Why is my CI failing?”
-
“What tests are flaky?”
-
“Show me the critical path in this pipeline.”
-
“Summarize the health of this project.”
And their coding agent can retrieve, analyze, and act on that information directly through Semaphore.
The first release includes:
-
Pipeline diagnostics
-
Flaky test detection
-
Critical path analysis
-
Organization-wide CI/CD insights
-
MCP support
-
Claude Code integrations
-
Remote execution workflows on Semaphore infrastructure
We also demonstrate how developers can provision ephemeral machines for agent-driven workflows, remote testing, and scalable execution.
Built for Agentic Workflows
Semaphore for AI Agents was designed specifically for AI-native development workflows.
The project ships with:
-
Agent-oriented commands
-
Structured JSON outputs
-
Claude Code skills
-
Generic agent skills
-
A local MCP server
This allows coding assistants to interact directly with Semaphore while developers stay inside their coding environment.
Fully Open Source
Semaphore for AI Agents is fully open source.
Developers can inspect how it works, extend workflows, contribute new commands, and build their own automations.
We believe AI-powered developer tooling should remain transparent, inspectable, and developer-controlled.
This Is Just the Beginning
Semaphore for AI Agents is the foundation for a broader direction we’re building toward at Semaphore:
-
Developers define intent
-
Agents handle repetitive execution
-
Semaphore provides the infrastructure and orchestration layer
Over the coming weeks, we’ll continue shipping new workflows, MCP capabilities, testing automation, and scalable agent execution features.
Watch the Demo
We recorded a full walkthrough showing:
-
CI/CD debugging workflows
-
MCP integrations
-
Claude Code usage
-
Organization-wide insights
-
Remote execution on Semaphore infrastructure

Modern development teams don’t all build on the same stack and they should not have to.
Today, we are expanding Semaphore’s capabilities to better support teams building on the Microsoft ecosystem, with first class support for the .NET framework and Microsoft Edge in CI pipelines.
This marks an important step toward making Semaphore a truly flexible platform for all developers, regardless of their technology choices.
Supporting More Developers, Where They Work
Until now, Semaphore has primarily focused on Linux native tooling and ecosystems. With this update, we are extending that foundation to support developers working with the Microsoft stack.
This includes:
-
.NET SDK support for building and compiling applications in CI
-
Microsoft Edge browser support for running end to end and UI tests
-
Full compatibility within Semaphore pipelines running on Linux
By enabling these tools, teams can now build, test, and validate .NET applications directly within Semaphore, without workarounds or custom environments.
Built on a Familiar, Reliable Foundation
This new support is already available in production, as part of our latest updates (see the changelog), and works on our latest Ubuntu 24.04 image.
You can learn more about the environment here.
By leveraging Linux compatible tooling for the Microsoft ecosystem, we are making it possible to run .NET workloads in the same scalable, reliable CI/CD environment teams already use for other stacks.
This approach keeps things simple:
-
No need to manage separate CI systems
-
No need to maintain custom infrastructure
-
No disruption to existing workflows
Just a consistent, unified pipeline experience.
Why This Matters
As development ecosystems continue to evolve, teams are increasingly working across multiple stacks and technologies.
Supporting .NET is not just about adding another SDK. It is about expanding what developers can do within a single CI/CD platform.
This aligns directly with our broader vision:
-
Reduce friction in software delivery
-
Automate the repetitive work behind building and testing
-
Let developers focus on what actually matters
As outlined in our 2026 product strategy, our goal is to remove unnecessary toil and make the right thing the easy thing inside CI/CD .
Bringing .NET into Semaphore is one more step toward that goal.
What’s Next
We have also prepared a simple demo project showcasing how to build and test a .NET application on Semaphore. You can access it here.
Alongside that, documentation updates and image changes are already available, and we will continue improving the experience based on feedback.
This is just the beginning.
As we continue expanding language and ecosystem support, our focus remains the same. Helping developers ship high quality software faster, with less manual effort.
Happy building!Pete Miloravac Semaphorehttps://semaphore.io

Today we’re introducing an important change to how Semaphore pricing works.
CICD is no longer something that runs occasionally during development. For many teams, it’s now always-on infrastructure that powers software delivery.
To support this shift, we’re introducing a new Semaphore pricing model designed to keep CICD fast, scalable, and affordable as usage grows.
What’s changing
The new model separates compute infrastructure from support and success services, giving teams more transparency and flexibility in how they use Semaphore.
Key updates include:
Lower machine pricing
Semaphore’s fastest runners are now available at significantly reduced prices, starting at $0.0075 per minute.
Our new f1 machines replace the previous e1 and e2 runners, focusing the platform on high-performance compute optimized for CICD workloads.
Usage-based pricing for self-hosted agents
Self-hosted agents are no longer billed per developer seat.Instead, usage is priced purely based on compute time at $0.0025 per minute.
Support and success plans are now separate
Infrastructure pricing now reflects compute consumption only.Teams can choose optional Support and Success plans depending on their operational needs and level of optimization guidance.
A modular approach to CICD
Teams can now combine:
-
Compute infrastructure
-
Support plans for operational reliability
-
Success plans for performance optimization
-
On-demand engineering assistance
This modular model makes it easier to scale Semaphore alongside your CICD usage.
For existing customers
Nothing changes immediately.
You can continue using your current plan as-is, and when you’re ready, you’ll be able to switch to the new pricing structure directly in the app.

We’re preparing a new update for the Semaphore MCP server that will make it easier for developers to connect AI agents and developer tools.
The focus of this update is authentication.
Today, connecting an agent to the MCP server typically requires using a long-lived API token. While this works well, it also means developers need to generate credentials, store them in configuration files, and manage them manually.
In our next release, coming next week, we’re introducing OAuth authentication support for the MCP server.
This will make connecting agents and developer tools significantly simpler.
Instead of generating and storing API tokens, developers will be able to authenticate through a familiar OAuth flow. When configuring an agent, a browser window opens, you log in, and approve access to the MCP server. Once approved, the connection is established automatically.
This approach removes the need to manage long-lived credentials and makes integrations easier to set up.
It also improves compatibility with modern agentic development tools. Some tools have limitations when working with static API tokens, and OAuth removes those barriers.

In this episode of Semaphore Uncut, Jamie Dobson, co-founder and former CEO of Container Solutions, shares a thoughtful perspective on generative AI, developer productivity, and system stability.
The conversation explores why recent research shows engineers feeling happier and more productive with AI tools—while system reliability quietly declines. Jamie explains how AI-generated code can appear correct while introducing subtle long-term risk, and why speed without deep understanding can be dangerous for growing systems.
They also discuss why looking back at the history of computing—from time-sharing to early neural networks—helps demystify today’s AI hype. The episode closes with a reflection on the stories we tell about technology, how humans and machines can work together, and what engineering leaders should be paying attention to next.

In this episode of Semaphore Uncut, Sebastian Gierlinger, VP of Engineering at Storyblok, shares what it really takes to scale a fully remote engineering organization—from early startup days to a 250-person company.
The conversation explores how Storyblok scaled engineering across multiple time zones without losing alignment or delivery speed. Sebastian explains why Scrum stopped working as the team grew, what changed after adopting Shape Up, and how specialization—if left unchecked—can quietly turn into a bottleneck for growing teams.
They also discuss what remote-first organizations need to get right as they scale, from decision-making and trust to execution at speed. The episode closes with a candid look at how AI is already changing day-to-day engineering work—and why scaling engineering is ultimately less about hiring faster and more about designing better systems.

AI agents can reason, but they don’t actually understand your systems. MCP servers fix that by giving your copilots and assistants structured access to your tools, APIs, and CI/CD data. And the best part is that building one is much simpler than most people expect.
In the latest episode of Technical Tips, Tommy walks through how to create a functional MCP server in just a few minutes. He connects it to Semaphore’s API, pulls real project data, and shows how to expose those insights to tools like OpenAI Codex. It’s a straightforward, hands-on demo that finally makes MCP feel practical instead of theoretical.
If you’ve been curious about MCP or you’re trying to make your AI tools genuinely useful in day-to-day engineering work, this is the perfect place to start. You’ll see how an MCP server communicates with AI clients, how to wrap a real API into it, how to test everything using the MCP Inspector, and how easily you can turn your CI/CD workflows into a conversational experience.
By the end, you’ll understand how surprisingly little code it takes to give your AI agents real operational awareness.
