An incident summary alone is not a regression test.https://www.useshifu.com/blog/context-handoff-planning-reviewhttps://www.useshifu.com/blog/context-handoff-planning-reviewFri, 06 Nov 2026 02:17:22 GMTUse one compact change record that evolves from problem and constraints to implementation decisions and verification evidence. Give each field an owner and an update trigger so the reviewer receives current understanding rather than a second reconstruction task.https://www.useshifu.com/blog/agents-md-or-task-contexthttps://www.useshifu.com/blog/agents-md-or-task-contextThu, 05 Nov 2026 04:40:40 GMTPut durable, broadly applicable guidance in project instructions. Keep changing decisions, current implementation state, and task-specific evidence in a checked brief with sources. Verify instruction discovery in the tool you actually use.https://www.useshifu.com/blog/retrieval-optimization-we-heldhttps://www.useshifu.com/blog/retrieval-optimization-we-heldThu, 05 Nov 2026 04:40:40 GMTOur candidate found the required records, but so did the baseline. Complete-task estimated cost rose, and one held-out caller answer became less useful. We retained the baseline because the candidate did not pass the gates defined for this study.https://www.useshifu.com/blog/give-agent-review-briefhttps://www.useshifu.com/blog/give-agent-review-briefWed, 04 Nov 2026 02:18:03 GMTGive the reviewer the problem, current behavior, applicable constraints, sources, and open questions before asking for findings. Then ask it to connect each finding to a concrete failure and a verification step.https://www.useshifu.com/blog/building-context-into-blog-postshttps://www.useshifu.com/blog/building-context-into-blog-postsWed, 04 Nov 2026 02:18:03 GMTWe used Shifu to recover relevant product history, checked it against current project evidence, and turned the results into article briefs. The useful part was the connection between a source, an editorial choice, and a claim we could support.https://www.useshifu.com/blog/recover-architecture-decisionshttps://www.useshifu.com/blog/recover-architecture-decisionsTue, 03 Nov 2026 02:12:43 GMTRecover a decision as a choice, reason, scope, status, and source. Check what still applies before handing it to an agent; a plausible historical explanation is not the current contract.https://www.useshifu.com/blog/summary-important-detailhttps://www.useshifu.com/blog/summary-important-detailTue, 03 Nov 2026 02:12:43 GMTA summary can preserve the topic while losing the condition that changes the next action. Check whether scope, current status, and verification survive—not only whether the output sounds faithful.https://www.useshifu.com/blog/measure-context-reconstructionhttps://www.useshifu.com/blog/measure-context-reconstructionMon, 02 Nov 2026 02:06:32 GMTMeasure the whole change, including context preparation and correction after coding. Compare similar work with a clear definition of completion, and keep faster-looking activity separate from a useful outcome.https://www.useshifu.com/blog/review-problem-not-only-diffhttps://www.useshifu.com/blog/review-problem-not-only-diffMon, 02 Nov 2026 02:06:32 GMTA diff shows a change. To judge whether it is the right change, a reviewer also needs the intended behavior, the constraints that must survive, and evidence for the checks that matter.https://www.useshifu.com/blog/claude-code-memory-contexthttps://www.useshifu.com/blog/claude-code-memory-contextSun, 01 Nov 2026 09:09:27 GMTUse project instructions for rules that should travel with ordinary tasks, native memory for inspectable learnings, and a task brief for the decisions and exceptions this change depends on. Start by checking what Claude actually loaded.https://www.useshifu.com/blog/why-context-enginehttps://www.useshifu.com/blog/why-context-engineSun, 01 Nov 2026 09:09:27 GMTWe are building Shifu so that decisions, constraints, and reasoning from earlier work can help the next task. The useful unit is an applicable piece of understanding with evidence—not merely a saved conversation.
