Email results look promising; repository results do not yet. An indication from a lab test, not production evidence.</description><pubDate>Thu, 22 Oct 2026 00:00:00 GMT</pubDate></item><item><title>New on AI SW Factory: token cost fundamentals for coding agents</title><link>https://mellicci.dev/writing/token-cost-fundamentals-course</link><guid isPermaLink="true">https://mellicci.dev/writing/token-cost-fundamentals-course</guid><description>A free, ten-page module on what a coding agent costs to run and why, built from four mechanics (re-reading, caching, expiry and generation) and ending with a controlled cost experiment you can run on your own work.</description><pubDate>Thu, 22 Oct 2026 00:00:00 GMT</pubDate></item><item><title>Token cost: is it cheaper to let an agent manage Kubernetes with CLI or MCP?</title><link>https://mellicci.dev/writing/cli-or-mcp-kubernetes-agent-token-cost</link><guid isPermaLink="true">https://mellicci.dev/writing/cli-or-mcp-kubernetes-agent-token-cost</guid><description>Four hypotheses tested in 40 measured agent runs across five Kubernetes operations (incident repair, a failed rollout, a capacity change, a memory fix and a Helm lifecycle), each evaluated per session with Agent Tokenwatch against independently verified success.</description><pubDate>Sat, 03 Oct 2026 00:00:00 GMT</pubDate></item></channel></rss>
