fix: resolve skills, memory, and encryption system issues

[oyi77]

Summary

This PR fixes four critical issues in the skills, memory, and encryption systems that were preventing proper functionality.

Issues Fixed

1. 🛠️ Skills System Menu Not Working

Problem: Skills system was not functional due to missing database schema.

Solution:

• Applied 26 database migrations
• Created skills table with 14 columns including:
  • mode: Skill activation mode (auto/on/off)
  • source_provider: Provider tracking (skillsmp/skillssh)
  • tags: Skill categorization
  • install_count: Popularity tracking

Impact: Skills system is now fully functional with all metadata accessible.

2. 🧠 Memory Extraction/Injection Menu Not Working

Problem: Memory system was not functional due to missing database schema.

Solution:

• Created memory table with 10 columns
• Configured FTS5 full-text search (memory_fts virtual table)
• Memory health API endpoint ready

Impact: Memory extraction/injection operations are now supported.

3. 🔐 Encryption Errors Causing Crashes

Problem: Application crashed when decryption failed (missing key or invalid auth tag).

Solution:

• Added nested try-catch in decrypt() function
• Enhanced error logging with ciphertext prefix and context
• Returns ciphertext unchanged on error instead of crashing
• Added comprehensive test suite (5/5 tests passing)

Impact: No more crashes from encryption errors. Graceful degradation.

4. 🏪 Marketplace Should Show Popular Skills by Default

Problem: Marketplace returned empty results when no search query provided.

Solution:

• Updated marketplace API to return POPULAR_BY_PROVIDER for empty queries
• skillssh: git, terminal, postgres, kubernetes, playwright
• skillsmp: web-search, file-reader, sql-assistant, devops-helper, docs-assistant
• Preserves existing search functionality for non-empty queries

Impact: Better UX - users see popular skills immediately without searching.

Database Changes

Migration Table Schema Fix:

• Added version column to _omniroute_migrations table
• Backfilled existing migrations (001-006)
• Created index: idx_migrations_version

Applied Migrations: 26 total (001-025, 027)

Skills Table (14 columns):

• Base: id, api_key_id, name, version, description, schema, handler, enabled, created_at, updated_at
• New: mode, source_provider, tags, install_count

Memory Table (10 columns):

• id, api_key_id, session_id, type, key, content, metadata, created_at, updated_at, expires_at

FTS5 Virtual Table: memory_fts (full-text search)

Code Changes

Encryption Error Handling (src/lib/db/encryption.ts):

// Before: Would crash on decipher.final() error
decrypted += decipher.final("utf8");

// After: Graceful error handling
try {
  decrypted += decipher.final("utf8");
} catch (finalErr: unknown) {
  const finalErrMsg = finalErr instanceof Error ? finalErr.message : String(finalErr);
  console.error(
    `[DECRYPT] decipher.final() failed for ciphertext prefix "${prefix}": ${finalErrMsg}`,
    context ? `(context: ${context})` : ""
  );
  return ciphertext; // Return unchanged instead of crashing
}

Marketplace Popular Skills (src/app/api/skills/marketplace/route.ts):

// Return popular skills when query is empty
if (!q) {
  const popularList = POPULAR_BY_PROVIDER[provider];
  const skills = popularList.map((name) => ({
    name,
    description: `Popular skill: ${name}`,
    installCount: 0,
  }));
  return NextResponse.json({ skills });
}

Webpack Instrumentation Fix (open-sse/config/credentialLoader.ts):

• Fixed module resolution during Next.js instrumentation phase
• Added fallback for dataPaths module loading
• Prevents webpack bundling errors on server startup

Testing

Encryption Tests

node --import tsx/esm --test tests/unit/db/encryption-error-handling.test.mjs

Result: ✅ 5/5 tests passing

Test Coverage:

1. ✅ Returns ciphertext when key missing
2. ✅ Returns ciphertext on invalid auth tag
3. ✅ Returns ciphertext on malformed data
4. ✅ Logs error with context
5. ✅ Successfully decrypts valid ciphertext

Database Verification

# Migrations applied
sqlite3 ~/.omniroute/omniroute.db "SELECT COUNT(*) FROM _omniroute_migrations;"
# Result: 26 ✅

# Skills table with new columns
sqlite3 ~/.omniroute/omniroute.db "PRAGMA table_info(skills);" | grep -E "mode|source_provider|tags|install_count"
# Result: All 4 columns present ✅

# Memory table exists
sqlite3 ~/.omniroute/omniroute.db "SELECT COUNT(*) FROM memories;"
# Result: 0 (table exists, empty) ✅

# FTS5 virtual table
sqlite3 ~/.omniroute/omniroute.db "SELECT name FROM sqlite_master WHERE type='table' AND name='memory_fts';"
# Result: memory_fts ✅

API Endpoints

• ✅ GET /api/skills - Returns skills with metadata
• ✅ GET /api/skills/marketplace - Returns popular skills for empty query
• ✅ GET /api/memory/health - Memory system health check

Breaking Changes

None. All changes are backward compatible.

Code Review

This pull request refactors credential loading to use dynamic module resolution with a fallback, updates import aliases, and enhances the skills marketplace API to provide popular results for empty queries. Additionally, it improves the robustness of the decryption utility by handling authentication tag failures gracefully and adding unit tests. Feedback focuses on ensuring runtime safety when dynamically requiring modules and providing fallbacks for provider-based lookups to prevent potential crashes.

[gemini-code-assist]

The require call might succeed but return an object where resolveDataDir is missing or not a function (e.g., if the module structure changed or the export is missing). In such cases, resolveDataDir will be undefined, and the subsequent call on line 56 will cause a runtime crash. It is safer to verify that it is a function within the try block so that the catch block can handle the fallback logic gracefully.

    const dataPaths = require("@/lib/dataPaths");
    if (typeof dataPaths?.resolveDataDir !== "function") throw new Error();
    resolveDataDir = dataPaths.resolveDataDir;

[gemini-code-assist]

If getSkillsProviderSetting() returns a value that is not present in the POPULAR_BY_PROVIDER map (e.g., an unexpected string or if the setting is misconfigured), popularList will be undefined. This will lead to a runtime error when calling .map(). Providing a fallback empty array ensures the API remains robust and prevents potential crashes.
