… to fix) Integrated all tools from hypercontext-mcp project including: - 11 advanced-caching tools - 10 api-database tools - 10 build-systems tools - 10 code-analysis tools - 5 configuration tools - 11 dashboard-monitoring tools - 11 file-operations tools - 10 intelligence tools - 7 output-formatting tools - 8 system-operations tools Current state: 1025 TypeScript compilation errors to systematically fix - Import path mismatches (hypercontext uses 'cache'/'tokens', token-optimizer uses 'cache-engine'/'token-counter') - Various type mismatches and missing exports - Unused variables and imports Next: Systematically fix with parallel AI agent teams 🤖 Generated with [Claude Code](https://claude.com/claude-code)
- Ran Prettier on all TypeScript files to fix collapsed formatting - Created AGENT-TEAM-PLAN.md with comprehensive fix strategy - Created baseline unused-imports.txt for Agent Alpha - Fixed formatting in 7 tool files Preparing for systematic error reduction with measurable goals.
Automated script removed unused imports identified by TS6133/TS6192 errors. This is Phase 1 (Agent Alpha) of systematic error reduction plan. Progress: - Total errors: 1025 → 844 (reduction of 181, 17.7% decrease) - TS6133/TS6192 errors: 316 → 144 (reduction of 172, 54.4% of unused imports fixed) - Files modified: 45 tool files - Imports removed: 168 Remaining work: - 144 unused import/variable errors remain (many in files with formatting issues) - Many errors are local variables (_tokenCounter, _metrics) not imports - 32 files have collapsed formatting on line 1 (comment block + import on single line) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
