MemPalace v3.3.3 Fixes Claude Code Plugin Install and Save Reliability

MemPalace v3.3.3 is a maintenance release focused on reliability for Claude Code integrations, transcript persistence, and metadata handling at scale. The update fixes a packaging regression that broke fresh installs, restores visibility into silent save failures, and improves hook and search behavior across different platforms and project layouts.

What Changed

The most important fix in v3.3.3 addresses an install regression affecting the mempalace-mcp console script. In v3.3.2, the Claude plugin configuration referenced a command that was not actually installed by pip, creating a broken out-of-the-box setup for fresh users. This release brings pyproject.toml and the Claude plugin definition back into alignment so the expected binary is installed correctly.

Another notable improvement restores visibility around silent-save failures triggered by a Claude Code 2.1.114 client regression. Production transcript saves had been failing without clear user feedback, and this release resolves that issue so save behavior is surfaced properly again.

For larger deployments, MemPalace now paginates metadata fetches on the status path. That prevents large palaces from exceeding SQLite variable limits, which should improve reliability for users managing bigger memory stores.

v3.3.3 also tightens plugin hook execution across platform and directory-layout differences. The hook runner now resolves more reliably on Windows and on some macOS plugin directory layouts that previously broke. Shell hook execution was improved as well, with proper python3 resolution and support for a MEMPAL_PYTHON override path.

The release includes several memory-organization fixes too. The optional wing parameter was added to diary read/write tools, and the stop hook can now derive a per-project wing from the Claude Code transcript path. That prevents diary entries from unrelated projects from collapsing into the same default wing. Search handling was also relaxed so empty-string values for optional wing and room filters are treated as no filter instead of causing validation errors.

Finally, the transcript-path wing derivation logic was broadened to handle more Claude Code project folder naming patterns, reducing edge-case failures in multi-project setups.

Why It Matters

This release matters because it improves the day-to-day trustworthiness of MemPalace in real AI-assisted development workflows. The install fix removes a high-friction onboarding failure for Claude Code users, while the save visibility and hook-resolution fixes reduce silent breakage that can undermine confidence in memory tooling.

For teams or power users running larger palaces and multiple concurrent projects, the pagination and wing-isolation improvements are especially useful. They make the system more resilient at scale and help preserve cleaner project boundaries in stored notes and diary entries.

Overall, MemPalace v3.3.3 is less about new headline features and more about making the existing Claude Code memory workflow safer, more portable, and more dependable.
