They are the ones designed around a specific objective — with the right tools, system prompt, skills, memory model, and operating environment.Thu, 23 Apr 2026 00:00:00 GMTaiagentsharness-engineeringhttps://fitrakacamarga.exe.xyz/blog/why-i-built-my-own-data-pipeline-tool/https://fitrakacamarga.exe.xyz/blog/why-i-built-my-own-data-pipeline-tool/After a decade building data infrastructure — from data scientist to CTO — I got tired of stitching together 5+ tools that don't talk to each other. So I built Seeknal — one CLI for pipelines, features, metrics, and AI analysis.Tue, 21 Apr 2026 00:00:00 GMTdatapipelinesstartup
