* feat: add domain management system with support for multiple domain profiles
- Introduced DomainManager class for loading and managing domain profiles.
- Added support for a default domain ('code') and fallback mechanisms.
- Implemented domain configuration validation and error handling.
- Created types for domain configuration, observation types, and concepts.
- Added new directory for domain profiles and ensured its existence.
- Updated SettingsDefaultsManager to include CLAUDE_MEM_DOMAIN setting.
* Refactor domain management to mode management
- Removed DomainManager class and replaced it with ModeManager for better clarity and functionality.
- Updated types from DomainConfig to ModeConfig and DomainPrompts to ModePrompts.
- Changed references from domains to modes in the settings and paths.
- Ensured backward compatibility by maintaining the fallback mechanism to the 'code' mode.
* feat: add migration 008 to support mode-agnostic observations and refactor service layer references in documentation
* feat: add new modes for code development and email investigation with detailed observation types and concepts
* Refactor observation parsing and prompt generation to incorporate mode-specific configurations
- Updated `parseObservations` function to use 'observation' as a universal fallback type instead of 'change', utilizing active mode's valid observation types.
- Modified `buildInitPrompt` and `buildContinuationPrompt` functions to accept a `ModeConfig` parameter, allowing for dynamic prompt content based on the active mode.
- Enhanced `ModePrompts` interface to include additional guidance for observers, such as recording focus and skip guidance.
- Adjusted the SDKAgent to load the active mode and pass it to prompt generation functions, ensuring prompts are tailored to the current mode's context.
* fix: correct mode prompt injection to preserve exact wording and type list visibility
- Add script to extract prompts from main branch prompts.ts into code.yaml
- Fix prompts.ts to show type list in XML template (e.g., "[ bugfix | feature | ... ]")
- Keep 'change' as fallback type in parser.ts (maintain backwards compatibility)
- Regenerate code.yaml with exact wording from original hardcoded prompts
- Build succeeds with no TypeScript errors
* fix: update ModeManager to load JSON mode files and improve validation
- Changed ModeManager to load mode configurations from JSON files instead of YAML.
- Removed the requirement for an "observation" type and updated validation to require at least one observation type.
- Updated fallback behavior in the parser to use the first type from the active mode's type list.
- Added comprehensive tests for mode loading, prompt injection, and parser integration, ensuring correct behavior across different modes.
- Introduced new mode JSON files for "Code Development" and "Email Investigation" with detailed observation types and prompts.
* Add mode configuration loading and update licensing information for Ragtime
- Implemented loading of mode configuration in WorkerService before database initialization.
- Added PolyForm Noncommercial License 1.0.0 to Ragtime directory.
- Created README.md for Ragtime with licensing details and usage guidelines.
* fix: add datasets directory to .gitignore to prevent accidental commits
* refactor: remove unused plugin package.json file
* chore: add package.json for claude-mem plugin with version 7.4.5
* refactor: remove outdated tests and improve error handling
- Deleted tests for ChromaSync error handling, smart install, strip memory tags, and user prompt tag stripping due to redundancy or outdated logic.
- Removed vitest configuration as it is no longer needed.
- Added a comprehensive implementation plan for fixing the modes system, addressing critical issues and improving functionality.
- Created a detailed test analysis report highlighting the quality and effectiveness of the current test suite, identifying areas for improvement.

* refactor: remove parser regression tests to streamline codebase
* docs: update CLAUDE.md to clarify test management and changelog generation
* refactor: remove migration008 for mode-agnostic observations
* Refactor observation type handling to use ModeManager for icons and emojis
- Removed direct mappings of observation types to icons and work emojis in context-generator, FormattingService, SearchManager, and TimelineService.
- Integrated ModeManager to dynamically retrieve icons and emojis based on the active mode.
- Improved maintainability by centralizing the logic for observation type representation.
* Refactor observation metadata constants and update context generator
- Removed the explicit declaration of OBSERVATION_TYPES and OBSERVATION_CONCEPTS from observation-metadata.ts.
- Introduced fallback default strings for DEFAULT_OBSERVATION_TYPES_STRING and DEFAULT_OBSERVATION_CONCEPTS_STRING.
- Updated context-generator.ts to utilize observation types and concepts from ModeManager instead of constants.
* refactor: remove intermediate error handling from hooks (Phase 1)
Apply "fail fast" error handling strategy - errors propagate and crash loud
instead of being caught, wrapped, and re-thrown at intermediate layers.
Changes:
- Remove try/catch around fetch calls in all hooks - let errors throw
- Add try/catch ONLY around JSON.parse at entry points
- Delete error-handler.ts and hook-error-handler.ts (no longer needed)
- Update worker-utils.ts: functions now throw instead of returning null
- Update transcript-parser.ts: throw on missing path, empty file, malformed JSON
- Remove all handleWorkerError, handleFetchError imports
Philosophy: If something breaks, we KNOW it broke. No silent failures.

* refactor: remove error swallowing from SQLite services (Phase 3)
Apply "fail fast" error handling strategy to database layer.
SessionStore.ts migrations:
- ensureWorkerPortColumn(): Remove outer try/catch, let it throw
- ensurePromptTrackingColumns(): Remove outer try/catch, let it throw
- removeSessionSummariesUniqueConstraint(): Keep inner transaction
rollback, remove outer catch
- addObservationHierarchicalFields(): Remove outer try/catch
- makeObservationsTextNullable(): Keep inner transaction rollback,
remove outer catch
- createUserPromptsTable(): Keep inner transaction rollback, remove
outer catch
- getFilesForSession(): Remove try/catch around JSON.parse
SessionSearch.ts:
- ensureFTSTables(): Remove try/catch, let it throw
Philosophy: Migration errors that are swallowed mean we think the
database is fine when it's not. Keep only inner transaction rollback
try/catch blocks.

* fix: Move summary prompts to mode files for multilingual support
Summary prompts were hardcoded in English in prompts.ts, breaking
multilingual support. Now properly mode-based:
- Added summary_instruction, summary_context_label,
summary_format_instruction, summary_footer to code.json
- Updated buildSummaryPrompt() to use mode fields instead of hardcoded text
- Added summary_footer with language instructions to all 10 language modes
- Language modes keep English prompts + language requirement footer
This fixes the gaslighting where we claimed full multilingual support
but summaries were still generated in English.

- Smart Install - Cached dependency checker (pre-hook script, not a lifecycle hook)
- Worker Service - HTTP API on port 37777 with web viewer UI and 10 search endpoints, managed by Bun
- SQLite Database - Stores sessions, observations, summaries
- mem-search Skill - Natural language queries with progressive disclosure
- Chroma Vector Database - Hybrid semantic + keyword search for intelligent context retrieval
See Architecture Overview for details.
mem-search Skill
Claude-Mem provides intelligent search through the mem-search skill that auto-invokes when you ask about past work:
How It Works:
- Just ask naturally: "What did we do last session?" or "Did we fix this bug before?"
- Claude automatically invokes the mem-search skill to find relevant context
Available Search Operations:
- Search Observations - Full-text search across observations
- Search Sessions - Full-text search across session summaries
- Search Prompts - Search raw user requests
- By Concept - Find by concept tags (discovery, problem-solution, pattern, etc.)
- By File - Find observations referencing specific files
- By Type - Find by type (decision, bugfix, feature, refactor, discovery, change)
- Recent Context - Get recent session context for a project
- Timeline - Get unified timeline of context around a specific point in time
- Timeline by Query - Search for observations and get timeline context around best match
- API Help - Get search API documentation
Example Natural Language Queries:
"What bugs did we fix last session?"
"How did we implement authentication?"
"What changes were made to worker-service.ts?"
"Show me recent work on this project"
"What was happening when we added the viewer UI?"
See Search Tools Guide for detailed examples.
Beta Features
Claude-Mem offers a beta channel with experimental features like Endless Mode (biomimetic memory architecture for extended sessions). Switch between stable and beta versions from the web viewer UI at http://localhost:37777 → Settings.
