It is now used to denote at least four different things — budget, working set, retrieval surface, and the agent's effective horizon — and the conflation is producing bad engineering decisions. A taxonomy, with the cases each definition should be reserved for. https://substratics.com/calendar/#upcoming-heading substratics-cal-2026-05-01-metric-survives-gaming Fri, 01 May 2026 00:00:00 +0000 Silas Quorum The Operators Measurement Following "Why Your Agent ROI Number Is Wrong," the next question: which measurements degrade least under Goodhart pressure when teams are explicitly rewarded for moving them? A working answer, drawn from three operator interviews, with the limits stated. https://substratics.com/calendar/#upcoming-heading substratics-cal-2026-05-05-tool-return-provenance Tue, 05 May 2026 00:00:00 +0000 Silas Quorum The Substrate Security & Advisories Every tool an agent calls returns data the agent treats as testimony. There is no common metadata convention for marking that testimony's source, freshness, or trust class. What partial conventions exist, where they conflict, and what an interim agent-side discipline looks like. https://substratics.com/calendar/#upcoming-heading substratics-cal-2026-05-08-onboarding-coworker Fri, 08 May 2026 00:00:00 +0000 Silas Quorum The Operators Governance & Community Most teams onboard agents the way they onboard tools: credentials, scope, done. The teams getting durable performance onboard them the way they onboard people: shadowing, graduated scope, named sponsor, review cadence. Why the second pattern produces results the first does not. https://substratics.com/calendar/#upcoming-heading substratics-cal-2026-05-12-retrieval-layer Tue, 12 May 2026 00:00:00 +0000 Silas Quorum The Substrate Context Engineering Prompt engineering moved from string-crafting to retrieval design somewhere in the last twelve months and most teams have not noticed. What the shift is, why prompt-engineering literature has gone quiet, and what discipline has replaced it where it has been replaced well. https://substratics.com/calendar/#upcoming-heading substratics-cal-2026-05-15-reviewing-pr Fri, 15 May 2026 00:00:00 +0000 Silas Quorum The Operators Practice A field manual for the human who has to approve work an agent did. Not a checklist — an account of the cognitive moves that distinguish review from rubber-stamp, with the failure modes named. First piece in the new Practice beat. https://substratics.com/calendar/#upcoming-heading substratics-cal-2026-05-19-substrate-slot Tue, 19 May 2026 00:00:00 +0000 Silas Quorum The Substrate Security & Advisories Held open for a real disclosure or technique landing in the prior two weeks. If nothing warrants treatment, falls back to a planned Context Engineering piece on eval-suite drift. https://substratics.com/calendar/#upcoming-heading substratics-cal-2026-05-22-coworker-case-files Fri, 22 May 2026 00:00:00 +0000 Silas Quorum The Operators Case Files Three operators, each running agent coworkers in production for ~90 days, on what changed about their team that they did not predict. Not a vendor case study — anonymized, structured around the surprises, not the wins.
