[{"type":"text","text":"## claude-mem plugin built and deployed to marketplace\n*Source: claude-mem://observation/10605*\n\n**Complete build pipeline executed: React viewer, worker service, search server, hooks compiled and synced to Claude marketplace directory**\n\nThe claude-mem plugin underwent a complete build and deployment cycle. The build system compiled all components including the React-based viewer UI, a CommonJS worker service, an ES module search server, and six specialized hooks for different lifecycle events (context, new session, save, summary, cleanup, and user messages). All compiled outputs were placed in the plugin/scripts/ directory. The build process then used rsync to synchronize the entire project to the Claude marketplace directory at ~/.claude/plugins/marketplaces/thedotmack/, transferring thousands of files including all node_modules dependencies. This deployment makes version 6.0.9 of the plugin available through the Claude marketplace with all required dependencies installed.\n\n---\nType: change | Facts: Build process compiled 6 hooks: context-hook, new-hook, save-hook, summary-hook, cleanup-hook, user-message-hook; Worker service built as worker-service.cjs (1337.16 KB) and search server as search-server.mjs (331.02 KB); React viewer built with bundled JavaScript, HTML template, font assets, and 4 SVG icon files; Plugin synced via rsync to ~/.claude/plugins/marketplaces/thedotmack/ with 11,751 files transferred; Package version 6.0.9 deployed with dependencies auto-installed in marketplace directory | Concepts: what-changed, how-it-works | Files: scripts/build-hooks.js, package.json, plugin/scripts/worker-service.cjs, plugin/scripts/search-server.mjs, plugin/scripts/context-hook.js, plugin/scripts/new-hook.js, plugin/scripts/save-hook.js, plugin/scripts/summary-hook.js, plugin/scripts/cleanup-hook.js, plugin/scripts/user-message-hook.js, plugin/ui/viewer-bundle.js, plugin/ui/viewer.html\n\n---\nDate: 11/17/2025, 9:03:34 PM\n\n---\n\n## Session Context Review for Endless Mode Phase 3\n*Source: claude-mem://observation/10554*\n\n**Reviewing progress on Phase 3 endless mode implementation with PreToolUse hook and SKIP_TOOLS optimization.**\n\nA context review was initiated to understand the current state of the endless mode implementation. Phase 3 work includes a PreToolUse hook with SKIP_TOOLS optimization that was created in a previous session (#S1937) but remains unbuilt and untested. This discovery phase aims to gather full observations from prior work to determine the next steps needed to complete the endless mode feature.\n\n---\nType: discovery | Facts: Session #S1937 previously created a PreToolUse hook with SKIP_TOOLS optimization; The PreToolUse hook has not yet been built or tested; Work is currently in Phase 3 of an endless mode implementation; Project located at /Users/alexnewman/Scripts/claude-mem | Concepts: how-it-works, what-changed\n\n---\nDate: 11/17/2025, 7:30:21 PM\n\n---\n\n## Added PreToolUse hook to lifecycle configuration\n*Source: claude-mem://observation/10541*\n\n**New PreToolUse hook executes pre-tool-use-hook.js before any tool is invoked by Claude.**\n\nA new PreToolUse lifecycle hook was added to the claude-mem plugin configuration to enable capturing state before tools are executed. This complements the existing PostToolUse hook that runs save-hook.js after tool execution. By adding pre-tool-use-hook.js with the same wildcard matcher and timeout settings as PostToolUse, the system can now monitor and potentially intercept or prepare for tool invocations before they occur. This creates a complete before/after hook pattern for tool usage tracking.\n\n---\nType: feature | Facts: Added PreToolUse hook section to plugin/hooks/hooks.json before the existing PostToolUse hook; PreToolUse hook runs pre-tool-use-hook.js script with 120s timeout; PreToolUse hook uses matcher \"*\" to trigger on all tool invocations; The hook system now captures both before and after states of tool usage | Concepts: what-changed, pattern, why-it-exists | Files: plugin/hooks/hooks.json\n\n---\nDate: 11/17/2025, 7:16:47 PM\n\n---\n\n## PreToolUse Hook Implementation for Transcript Transformation\n*Source: claude-mem://observation/10540*\n\n**Created hook that transforms previous tool results into observation references before each tool execution.**\n\nA new PreToolUse hook was implemented to handle the transformation of tool results into observation references in the transcript. The hook executes before each tool use, ensuring that the previous tool's result has already been written to the transcript file. It searches the transcript backwards to find the most recent tool_result that hasn't been transformed yet (identified by not containing \"[Observation #\"). When found, it sends a synchronous POST request to the worker's transform endpoint with the tool_use_id. If the worker successfully creates an observation, the hook modifies the transcript file in-place, replacing the full tool result content with a compact reference like \"[Observation #123: Title]\". The implementation elegantly handles edge cases: first tool use (no previous tool), already-transformed results, disabled endless mode, and worker failures—all by simply returning success and continuing. This design fulfills the architectural decision to consolidate logic in PreToolUse while avoiding YAGNI violations.\n\n---\nType: feature | Facts: Pre-tool-use hook processes the PREVIOUS tool's result, guaranteeing it's already in transcript; Hook searches transcript backwards to find most recent untransformed tool_result entry; Transformed tool_result content becomes compact reference format: \"[Observation #ID: Title]\"; Hook communicates with worker via POST to /sessions/{id}/observations/transform endpoint; SKIP_TOOLS set filters out low-value tools: ListMcpResourcesTool, SlashCommand, Skill, TodoWrite, AskUserQuestion; Hook gracefully handles first tool use case by checking if previousTool is null; Transformation only occurs when EndlessModeConfig.enabled is true and transcript_path exists; Worker returns ObservationEndpointResponse with status: queued, completed, or timeout | Concepts: how-it-works, pattern, problem-solution | Files: src/hooks/pre-tool-use-hook.ts\n\n---\nDate: 11/17/2025, 7:16:07 PM\n\n---\n\n## Moving All Logic to PreToolUse Hook\n*Source: claude-mem://observation/10538*\n\n**Decision to implement all functionality in PreToolUse hook to guarantee previous tool use is available.**\n\nA new architectural decision was made to consolidate all functionality into the PreToolUse hook. This approach was chosen because PreToolUse guarantees that the previous tool use will be available in the context, which is essential for the intended functionality. The decision explicitly avoids over-engineering (YAGNI - You Aren't Gonna Need It) while acknowledging that the first tool use scenario may require smart handling since there would be no previous tool use at that point. This represents a simplification of the architecture by using a single hook point rather than distributing logic across multiple hooks.\n\n---\nType: decision | Facts: All logic will be moved to the PreToolUse hook instead of other lifecycle hooks; PreToolUse hook guarantees that the previous tool use is in context; The approach avoids YAGNI (You Aren't Gonna Need It) principle violations; Special handling may be needed for the first tool use edge case | Concepts: pattern, why-it-exists, trade-off\n\n---\nDate: 11/17/2025, 7:13:35 PM"}]
