Before Growing Hermes Agent: Creating Synthetic Support Triage Scenarios
As a preparatory step before delegating support triage to Hermes Agent, I built three evaluation scenarios using synthetic data—fixing decision criteria and safety constraints in advance without relying on real customer data.
Observing the Sakana Fugu API with Langfuse: Understanding Hidden Costs in Multi-Agent Systems
A hands-on report instrumenting Sakana Fugu's OpenAI-compatible API with Langfuse, measuring how latency, token consumption, and TTFT change across Level 1–3 tasks.
Eve's TUI vs HTTP Event Streams: A Side-by-Side Look at Tool Calling
A hands-on log comparing how the same weather tool call looks in Vercel's Eve agent framework when observed from the TUI versus the HTTP API, separating the developer-friendly display from the integration-friendly event stream.
Observing the Black Box of a Multi-Agent API with Sakana Fugu and Langfuse
I subscribed to Sakana Fugu to understand its nature as an OpenAI-compatible API and to plan how to observe its black-box cooperative reasoning from the outside.
Streaming Flue Observe Events to Langfuse: Monitoring an Issue Triage Agent
An experiment log where I redact Flue 1.0 Beta observe events before sending them to Langfuse, tracking the issue triage workflow's runId, model, and results.
Observing Eve TUI Execution and Tool Calls with Langfuse
A hands-on comparison of two ways to send Eve tool-calling executions to Langfuse as trace/span/generation data.
Building a Tool-Calling Agent with Vercel's Eve and Running It from the TUI
A follow-up to my first look: adding tools and evals to Eve, configuring models via the Vercel AI Gateway, invoking tools from the TUI, and exploring the info and eval commands.
Moving Issue Triage into CI: Running a Flue Workflow from GitHub Actions
A verification log of dry-running a GitHub Issue triage workflow built with Flue 1.0 Beta from GitHub Actions' issues.opened, instead of a persistent webhook server.
Building a GitHub Issue Triage Agent with Flue 1.0 Beta
An experimental log of building a triage agent with Flue 1.0 Beta's Agent, Skill, and Workflow features that returns structured severity, reproducibility, and label suggestions for GitHub issues.
A Quick Look at Eve, Vercel's New Agent Framework
A quick validation log of running Vercel's open-source agent framework Eve locally through init, dev startup, and the first session.
Before Using Flue: Figuring Out What This Framework Actually Is
A rough summary of how Flue thinks about harnesses, agents, workflows, skills, tools, sandboxes, and persistence — before actually running anything.
