All information you need is provided in <observed_from_primary_session> messages. Create observations from what you observe - no investigation needed.\n\nYour job is to monitor a different Claude Code session happening RIGHT NOW, with the goal of creating observations and progress summaries as the work is being done LIVE by the user. You are NOT the one doing the work - you are ONLY observing and recording what is being built, fixed, deployed, or configured in the other session.\n\nSPATIAL AWARENESS: Tool executions include the working directory (tool_cwd) to help you understand:\n- Which repository/project is being worked on\n- Where files are located relative to the project root\n- How to match requested paths to actual execution paths\n\nWHAT TO RECORD\n--------------\nFocus on durable technical signal:\n- What the system NOW DOES differently (new capabilities)\n- What shipped to users/production (features, fixes, configs, docs)\n- Changes in technical domains (auth, data, UI, infra, DevOps, docs)\n- Concrete debugging or investigative findings from logs, traces, queue state, database rows, and code-path inspection\n\nUse verbs like: implemented, fixed, deployed, configured, migrated, optimized, added, refactored, discovered, confirmed, traced\n\n✅ GOOD EXAMPLES (describes what was built or learned):\n- \"Authentication now supports OAuth2 with PKCE flow\"\n- \"Deployment pipeline runs canary releases with auto-rollback\"\n- \"Database indexes optimized for common query patterns\"\n- \"Observation queue for claude-mem session timed out waiting for an agent pool slot\"\n- \"Fallback processing abandoned pending messages after Gemini and OpenRouter returned 404\"\n\n❌ BAD EXAMPLES (describes observation process - DO NOT DO THIS):\n- \"Analyzed authentication implementation and stored findings\"\n- \"Tracked deployment steps and logged outcomes\"\n- \"Monitored database performance and recorded metrics\"\n\nWHEN TO SKIP\n------------\nSkip routine operations:\n- Empty status checks\n- Package installations with no errors\n- Simple file listings with no follow-on finding\n- Repetitive operations you've already documented\n- File related research that comes back empty or not found\n\nIf skipping, return an empty response only. Do not explain the skip in prose.\n\nIMPORTANT: Continue generating observations from tool use messages using the XML structure below.\n\nOUTPUT FORMAT\n-------------\nOutput observations using this XML structure:\n\n<observation>\n  <type>[ bugfix | feature | refactor | change | discovery | decision | security_alert | security_note ]</type>\n  \n  <title>[title: Short title capturing the core action or topic]</title>\n  <subtitle>[subtitle: One sentence explanation (max 24 words)]</subt\n…(truncated, 2227 more chars)\n\nTurn 1 — Assistant\n\n(No observations yet - initial file listings only, work not yet started on bug fix)\n\nTurn 2 — User\n\n<observed_from_primary_session>\n  <what_happened>Write</what_happened>\n  <occurred_at>2026-05-18T10:16:05.896Z</occurred_at>\n  <working_directory>/Users/USER/workspace/doctolib/doctolib</working_directory>\n  <parameters>\"{\\\"file_path\\\":\\\"/Users/USER/Library/CloudStorage/<REDACTED>/My Drive/ai-artifacts/duty/FHIR-2183/plan.html\\\",\\\"content\\\":\\\"<!DOCTYPE html>\\\\n<html lang=\\\\\\\"en\\\\\\\">\\\\n<head>\\\\n  <meta charset=\\\\\\\"UTF-8\\\\\\\" />\\\\n  <meta name=\\\\\\\"viewport\\\\\\\" content=\\\\\\\"width=device-width, initial-scale=1.0\\\\\\\" />\\\\n  <title>FHIR-2183 — Fix Plan</title>\\\\n  <style>\\\\n    , ::before, ::after { box-sizing: border-box;

issue only affects developer/QA testing without page reload</fact>\n    <fact>Design decision: Use isTiConnectorEnabled (intent-based naming, not geography-based) as the selector variable</fact>\n  </facts>\n  <narrative>\nFHIR-2183 is a React Rules of Hooks violation in the ti_connect package. The useTiConnector hook selects between two implementations based on product line: useTiConnectorReal (Germany/EhrGermany) calls 18+ hooks, while useTiConnectorNoop (all others) calls 2 hooks. When AccountContext changes the product line during a session—such as a developer switching countries in QA without a page reload—React re-renders and encounters a different hook count, violating the Rules of Hooks.\n\nThe fix normalizes hook count by always calling useTiConnectorReal with an enabled parameter. When disabled (non-Germany product lines), the enabled flag gates both React Query enabled options and the callTiConnect logic. The callTiConnect function checks enabled at call time: if false, it calls onSuccess(undefined) and returns early, preserving the noop contract without invoking the connector service.\n\nThis is a structural fix with no reload guard or error boundary. The design maintains backward compatibility: disabled product lines still receive undefined from the noop behavior, matching the existing contract.\n  </narrative>\n  <concepts>\n    <concept>why-it-exists</concept>\n    <concept>problem-solution</concept>\n    <concept>pattern</concept>\n    <concept>gotcha</concept>\n  </concepts>\n  <files_read>\n  </files_read>\n  <files_modified>\n  </files_modified>\n</observation>\n\nTurn 3 — User\n\n--- MODE SWITCH: PROGRESS SUMMARY ---\n⚠️ CRITICAL TAG REQUIREMENT — READ CAREFULLY:\n• You MUST wrap your ENTIRE response in <summary>...</summary> tags.\n• Do NOT use <observation> tags. <observation> output will be DISCARDED and cause a system error.\n• The ONLY accepted root tag is <summary>. Any other root tag is a protocol violation.\n\nPROGRESS SUMMARY CHECKPOINT\n===========================\nWrite progress notes of what was done, what was learned, and what's next. This is a checkpoint to capture progress so far. The session is ongoing - you may receive more requests and tool executions after this summary. Write \"next_steps\" as the current trajectory of work (what's actively being worked on or coming up next), not as post-session future work. Always write at least a minimal summary explaining current progress, even if work is still in early stages, so that users see a summary output tied to each request.\n\nClaude's Full Response to User:\nPlan exported to ai-artifacts/duty/FHIR-2183/plan.html.\n\n★ Insight ─────────────────────────────────────\nThe root fix here follows a fundamental React principle: hooks must be called unconditionally and in the same order on every render. The idiomatic solution is never \"choose between two hook implementations\" — it's \"always call one hook and use parameters to control its behavior.\" The enabled flag pattern is exactly how React Query was designed: the hook is always called, but its side effects are gated.\n─────────────────────────────────────────────────\n\nReady to implement? The plan is locked: delete useTiConnectorNoop, add { enabled: boolean } to useTiConnectorReal, rewrite useTiConnector to derive isTiConnectorEnabled from product line variation, and add a disabled-path test block.\n\nRespond in this XML format:\n<summary>\n  <request>[Short title capturing the user's request AND the substance of what was discussed/done]</request>\n  <investigated>[What has been explored so far? What was examined?]</investigated>\n  <learned>[What have you learned about how things work?]</learned>\n  <completed>[What work has been completed so far? What has shipped or changed?]</completed>\n  <next_steps>[What are you actively working on or planning to work on next in this session?]</next_steps>\n  <notes>[Additional insights or observations about the current progress]</notes>\n</summary>\n\nREMINDER: Your response MUST use <summary> as the root tag, NOT <observation>.\nIMPORTANT! DO NOT do any work right now other than generating this next PROGRESS SUMMARY - and remember that you are a memory agent designed to summarize a DIFFERENT claude code session, not this one.\n\nNever reference yourself or your own actions. Do not output anything other than the summary content formatted in the XML structure above. All other output is ignored by the system, and the system has been designed to be smart about token usage. Please spend your tokens wisely on useful summary content.\n\nThank you, this summary will be very useful for keeping track of our progress!\n\nTurn 3 — Assistant\n\n<summary>\n  <request>Fix FHIR-2183: React Rules of Hooks violation in useTiConnector by normalizing hook count with enabled parameter pattern</request>\n  <investigated>Analyzed the useTiConnector hook which conditionally selects between two implementations (useTiConnectorReal with 18+ hooks for Germany vs useTiConnectorNoop with 2 hooks for other product lines); identified that product line changes during a session cause React to encounter different hook counts on re-render</investigated>\n  <learned>Root cause: conditional hook selection violates React's Rules of Hooks — hooks must always be called in the same order on every render.
