feat: optimize MCP tool descriptions for 65-70% token reduction

- Reduced average description length from 250-450 to 93-129 chars
- Documentation tools now average 129 chars per description
- Management tools average just 93 chars per description
- Moved detailed documentation to tools_documentation() system
- Only 2 tools exceed 200 chars (necessarily verbose)

Also includes search_nodes improvements:
- Fixed primary node ranking (webhook, HTTP Request now appear first)
- Fixed FUZZY mode threshold for better typo tolerance
- Removed unnecessary searchInfo messages
- Fixed HTTP node type case sensitivity issue

This significantly improves AI agent performance by reducing context usage
while preserving all essential information.

+## [2.7.11] - 2025-07-10
+
+### Enhanced
+- **Token Efficiency**: Significantly reduced MCP tool description lengths for better AI agent performance
+  - Documentation tools: Average 129 chars (down from ~250-450)
+  - Management tools: Average 93 chars (down from ~200-400)
+  - Overall token reduction: ~65-70%
+  - Moved detailed documentation to `tools_documentation()` system
+  - Only 2 tools exceed 200 chars (list_nodes: 204, n8n_update_partial_workflow: 284)
+  - Preserved all essential information while removing redundancy
+
+### Fixed
+- **search_nodes Tool**: Major improvements to search functionality for AI agents
+  - Primary nodes (webhook, httpRequest) now appear first in search results instead of being buried
+  - Fixed issue where searching "webhook" returned specialized triggers instead of the main Webhook node
+  - Fixed issue where searching "http call" didn't prioritize HTTP Request node
+  - Fixed FUZZY mode returning no results for typos like "slak" (lowered threshold from 300 to 200)
+  - Removed unnecessary searchInfo messages that appeared on every search
+  - Fixed HTTP node type comparison case sensitivity issue
+  - Implemented relevance-based ranking with special boosting for primary nodes
+
+### Added
+- **FTS5 Full-Text Search**: Added SQLite FTS5 support for faster and more intelligent node searching
+  - Automatic fallback to LIKE queries if FTS5 is unavailable
+  - Supports advanced search modes: OR (default), AND (all terms required), FUZZY (typo-tolerant)
+  - Significantly improves search performance for large databases
+  - FUZZY mode now uses edit distance (Levenshtein) for better typo tolerance

+# Token Efficiency Improvements Summary
+
+## Overview
+Made all MCP tool descriptions concise and token-efficient while preserving essential information.
+
+## Key Improvements
+
+### Before vs After Examples
+
+1. **search_nodes**
+   - Before: ~350 chars with verbose explanation
+   - After: 165 chars
+   - `Search nodes by keywords. Modes: OR (any word), AND (all words), FUZZY (typos OK). Primary nodes ranked first. Examples: "webhook"→Webhook, "http call"→HTTP Request.`
+
+2. **get_node_info**
+   - Before: ~450 chars with warnings about size
+   - After: 174 chars
+   - `Get FULL node schema (100KB+). TIP: Use get_node_essentials first! Returns all properties/operations/credentials. Prefix required: "nodes-base.httpRequest" not "httpRequest".`
+
+3. **validate_node_minimal**
+   - Before: ~350 chars explaining what it doesn't do
+   - After: 102 chars
+   - `Fast check for missing required fields only. No warnings/suggestions. Returns: list of missing fields.`
+
+4. **get_property_dependencies**
+   - Before: ~400 chars with full example
+   - After: 131 chars
+   - `Shows property dependencies and visibility rules. Example: sendBody=true reveals body fields. Test visibility with optional config.`
+
+## Statistics
+
+### Documentation Tools (22 tools)
+- Average description length: **129 characters**
+- Total characters: 2,836
+- Tools over 200 chars: 1 (list_nodes at 204)
+
+### Management Tools (17 tools)
+- Average description length: **93 characters**
+- Total characters: 1,578
+- Tools over 200 chars: 1 (n8n_update_partial_workflow at 284)
+
+## Strategy Used
+
+1. **Remove redundancy**: Eliminated repeated information available in parameter descriptions
+2. **Use abbreviations**: "vs" instead of "versus", "&" instead of "and" where appropriate
+3. **Compact examples**: `"webhook"→Webhook` instead of verbose explanations
+4. **Direct language**: "Fast check" instead of "Quick validation that only checks"
+5. **Move details to documentation**: Complex tools reference `tools_documentation()` for full details
+6. **Essential info only**: Focus on what the tool does, not how it works internally
+
+## Special Cases
+
+### n8n_update_partial_workflow
+This tool's description is necessarily longer (284 chars) because:
+- Lists all 13 operation types
+- Critical for users to know available operations
+- Directs to full documentation for details
+
+### Complex Documentation Preserved
+For tools like `n8n_update_partial_workflow`, detailed documentation was moved to `tools-documentation.ts` rather than deleted, ensuring users can still access comprehensive information when needed.
+
+## Impact
+- **Token savings**: ~65-70% reduction in description tokens
+- **Faster AI responses**: Less context used for tool descriptions
+- **Better UX**: Clearer, more scannable tool list
+- **Maintained functionality**: All essential information preserved

-PARAMETERS:
-• id (required) - Workflow ID to update
-• operations (required) - Array of operations to apply (max 5)
-• validateOnly (optional) - Test operations without applying (default: false)
-
-TRANSACTIONAL UPDATES (v2.7.0+):
-• Maximum 5 operations per request for reliability
-• Two-pass processing: nodes first, then connections/metadata
-• Add nodes and connect them in the same request
-• Operations can be in any order - engine handles dependencies
-
-IMPORTANT NOTES:
-• Operations are atomic - all succeed or all fail
-• Use validateOnly: true to test before applying
-• Node references use NAME, not ID (except in node definition)
-• updateNode with nested paths: use dot notation like "parameters.values[0]"
-• All nodes require: id, name, type, typeVersion, position, parameters
-
