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)]</subtitle>\n  <facts>\n    <fact>[Concise, self-contained statement]</fact>\n    <fact>[Concise, self-contained statement]</fact>\n    <fact>[Concise, self-contained statement]</fact>\n  </facts>\n  <!--\n    facts: Concise, self-contained statements\nEach fact is ONE piece of information\n      No pronouns - each fact must stand alone\n      Include specific details: filenames, functions, va\n…(truncated, 1843 more chars)\n\nTurn 1 — Assistant\n\n[No tool executions observed.

The lastInteraction=None state indicates the earlier summarize operation (session-94) remains under processing, while the observation capture continues in parallel.</narrative>\n  <concepts>\n    <concept>how-it-works</concept>\n    <concept>pattern</concept>\n  </concepts>\n  <files_read>\n    <file>~/.claude-mem/logs/claude-mem-2026-05-27.log</file>\n  </files_read>\n  <files_modified>\n  </files_modified>\n</observation>\n\nTurn 6 — User\n\n<observed_from_primary_session>\n  <what_happened>Bash</what_happened>\n  <occurred_at>2026-05-27T14:48:01.053Z</occurred_at>\n  <working_directory>/Users/clertonra</working_directory>\n  <parameters>\"{\\\"command\\\":\\\"grep \\\\\\\"session-94\\\\\\\\|summarize\\\\\\\" ~/.claude-mem/logs/claude-mem-2026-05-27.log | grep -v \\\\\\\"HOOK\\\\\\\\|ENQUEUE\\\\\\\" | tail -10\\\",\\\"description\\\":\\\"Check session-94 summarize completion status in worker log\\\"}\"</parameters>\n  <outcome>\"{\\\"stdout\\\":\\\"find ~/.claude -name \\\\\\\"*.json\\\\\\\" 2>/dev/null | xargs grep -l \\\\\\\"session-init\\\\\\\\|summarize\\\\\\\\|claude-code observation\\\\\\\" 2>/dev/null | grep -v cache)\\\\necho '{\\\\\\\"session_id\\\\\\\":\\\\\\\"test-123\\\\\\\",\\\\\\\"transcript_path\\\\\\\":\\\\\\\"/tmp/test.jsonl\\\\\\\"}' | node ~/.claude/plugins/cache/thedotmack/claude-mem/13.3.0/scripts/bun-runner.js ~/.claude/plugins/cache/thedotmack/claude-mem/13.3.0/scripts/worker-service.cjs hook claude-code summarize 2>&1 | head -30)\\\\n  hook claude-code summarize 2>&1)\\\\ngrep -n \\\\\\\"summarize\\\\\\\\|lastInteraction\\\\\\\\|ai\\\\\\\\|queue\\\\\\\\|pending\\\\\\\" ~/.claude/plugins/cache/thedotmack/claude-mem/13.3.0/scripts/worker-service.cjs 2>/dev/null | head -30)\\\\n  hook claude-code summarize 2>&1)\\\\n[2026-05-27 16:47:02.422] [INFO ] [SESSION] [session-94] Session initialized {project=doctolib, contentSessionId=3a4956dd-feb7-47c1-8eba-15bd2f6d08e1, queueDepth=0, hasGenerator=false}\\\\n[2026-05-27 16:47:02.425] [INFO ] [SESSION] [session-94] Generator auto-starting (summarize) using Claude SDK {queueDepth=1, historyLength=0}\\\\n  hook claude-code summarize 2>&1 && echo \\\\\\\"Hook submitted, waiting 15s for AI to process...\\\\\\\" && sleep 15 && grep -i \\\\\\\"summarize\\\\\\\\|generator\\\\\\\\|error\\\\\\\\|session-3a4956\\\\\\\" ~/.claude-mem/logs/claude-mem-2026-05-27.log 2>/dev/null | tail -15)\\\\n  hook claude-code summarize 2>&1 && echo \\\\\\\"Hook submitted, waiting 15s for AI to process...\\\\\\\" && sleep 15 && grep -i \\\\\\\"summarize\\\\\\\\|generator\\\\\\\\|error\\\\\\\\|session-3a4956\\\\\\\" ~/.claude-mem/logs/claude-mem-2026-05-27.log 2>/dev/null | tail -15) | depth=1\\\\n  <title>claude-mem summarize hook processes successfu...\\\",\\\"stderr\\\":\\\"\\\",\\\"interrupted\\\":false,\\\"isImage\\\":false,\\\"noOutputExpected\\\":false}\"</outcome>\n</observed_from_primary_session>\n\nReturn either one or more <observation>...</observation> blocks, or an empty response if this tool use should be skipped.\nConcrete debugging findings from logs, queue state, database rows, session routing, or code-path inspection count as durable discoveries and should be recorded.\nNever reply with prose such as \"Skipping\", \"No substantive tool executions\", or any explanation outside XML.

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:\nThe fix is confirmed working — the worker is running, session-94 summarize is queued and the generator started. The 1.4MB transcript will take a few minutes to summarize.\n\nHere's the complete diagnosis and fix:\n\n---\n\nRoot cause: CLAUDE_CODE_PATH was empty in ~/.claude-mem/settings.json. The worker daemon runs in a minimal shell environment (started by the SessionStart hook) without ~/.local/bin on its PATH — so it couldn't find the claude executable needed to call the AI for session summarization. This started failing on May 22 with:\nERROR: Generator failed — Claude executable not found\n\nThis is the same PATH-isolation problem that was fixed in May 20 for node, but for a different binary.\n\nFix applied:\n1. Set CLAUDE_CODE_PATH: \"/Users/USER/.local/bin/claude\" in ~/.claude-mem/settings.json — this is a stable symlink that auto-updates when Claude Code updates\n2. Restarted the worker daemon (new pid 16212) to pick up the change\n\nGoing forward: Session summaries will be generated automatically again after each session ends. The ~/.local/bin/claude symlink will continue working after Claude Code version updates.\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?

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.

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 11 — Assistant\n\n<summary>\n  <request>Verify claude-mem worker service is working properly after May 22 summarization failure</request>\n  <investigated>\n    • Worker daemon health endpoint and process status (PID 16212, uptime tracking)\n    • Session-94 summarize hook submission and queue processing (message ID 18924)\n    • Worker logs for session initialization, message enqueuing, and generator auto-start\n    • SDK response parsing and completion status markers in logs\n    • Session lifecycle and reuse patterns across multiple sessions (116, 117, 94)\n    • Queue depth management and concurrent session handling (4 active sessions)\n    • PARSER warnings and SDK response validation failures in logs\n  </investigated>\n  <learned>\n    • Worker daemon starts successfully with OAuth <REDACTED> from system keychain\n    • Session routing and queue management work correctly: messages enqueued with proper depth tracking and session DB IDs\n    • Generator auto-starts immediately when messages are enqueued (promptType=SUMMARIZE for session-94)\n    • Known issue #817: stale memory_session_id from previous worker instance causes SDK context loss on restart\n    • Multiple sessions experience parser warnings (\"SDK returned non-XML/empty response\") followed by valid responses received (1791-1824 chars), suggesting race condition in response handling\n    • Observation-type messages do not update lastInteraction field; lastInteraction remains None even after summarize hook processing begins\n    • Session-94 summarize operation enqueued successfully but completion markers missing from logs over 97+ second window\n  </learned>\n  <completed>\n    • Worker daemon verified healthy and running (PID 16212, uptime ~97 seconds)\n    • Summarize hook successfully submitted and enqueued to session-94 queue (message ID 18924, depth=1)\n    • Generator auto-started for summarize operation using Claude SDK\n    • Health endpoint confirms MCP ready and worker operational\n    • Root cause identified: CLAUDE_CODE_PATH empty in ~/.claude-mem/settings.json preventing claude executable access\n    • Fix applied: CLAUDE_CODE_PATH set to /Users/USER/.local/bin/claude in settings\n    • Worker daemon restarted to load configuration change (PID 16212)\n  </completed>\n  <next_steps>\n    • Session-94 summarize operation in-flight (1.4MB transcript processing estimated to take several minutes)\n    • Monitor session-94 logs for completion markers and COMPLETE status\n    • Verify SDK response parsing completes successfully for summarize message\n    • Confirm session summary is written and lastInteraction field updates after completion\n    • Validate that session summaries auto-generate on subsequent session ends with restored CLAUDE_CODE_PATH\n  </next_steps>\n  <notes>\n    The claude-mem service is operational but was unable to generate session summaries due to PATH isolation in the worker daemon environment. The fix establishes a stable symlink path that will auto-update with Claude Code version updates. Multiple sessions show consistent parser warning patterns that may indicate timing issues between response validation and buffering. Session-94 summarize processing is proceeding but lacks completion logging, which will be visible once response parsing succeeds.\n  </notes>\n</summary>",
