feat: Complete Skill #5 - n8n Node Configuration (ALL 5 SKILLS COMPLETE!)
Implements operation-aware node configuration with progressive discovery.
Completes the final skill in the 5-skill n8n meta-skill collection.
Files created:
- 4 evaluations testing dependencies, operations, conditional fields, tool selection
- SKILL.md (692 lines) - Configuration workflow, progressive discovery, patterns
- DEPENDENCIES.md (671 lines) - displayOptions mechanism, dependency patterns
- OPERATION_PATTERNS.md (783 lines) - 20+ nodes with common configurations
- README.md (380 lines) - Skill metadata with usage statistics
Key features:
- Operation-aware configuration (resource + operation = requirements)
- Property dependencies (displayOptions show/hide rules)
- Progressive discovery (essentials → dependencies → info)
- Configuration workflow (identify → discover → configure → validate → iterate)
- 4 common node patterns (resource/operation, HTTP, database, conditional)
- Tool selection guide (get_node_essentials 91.7% success rate)
- Dependency troubleshooting (field visibility, conditional requirements)
- 20+ node configuration examples with gotchas
Progressive discovery strategy:
1. get_node_essentials (91.7% success, 18s avg from search)
2. get_property_dependencies (when dependencies unclear)
3. get_node_info (only when necessary, full schema)
Property dependency patterns:
- Boolean toggle (sendBody → body)
- Resource/operation cascade (different ops → different fields)
- Type-specific config (string vs number conditions)
- Method-specific fields (GET vs POST)
Common node patterns covered:
- HTTP Request (GET/POST/PUT/DELETE with auth, query, body)
- Webhook (basic/auth/response, $json.body gotcha)
- Slack (post/update/create channel)
- Gmail (send/get with filters)
- Postgres (query/insert/update with parameters)
- Set (fixed values/mapping with types)
- Code (per-item/all-items, no expressions!)
- IF (string/number/boolean, unary vs binary)
- Switch (rules with fallback)
- OpenAI (chat completion with system prompt)
- Schedule (daily/interval/cron with timezone)
Key insights:
- 91.7% configurations succeed with essentials only
- Average 56 seconds between configuration edits (iterative)
- 9,835 essentials calls vs fewer full schema calls
- 18 seconds average from node search to essentials
- Different operations = different requirements (always check!)
Top 5 gotchas documented:
1. Webhook data under $json.body (not $json)
2. POST needs sendBody: true
3. Slack channel format (#name for public)
4. SQL parameterized queries (prevent injection)
5. Schedule timezone must be explicit (DST handling)
displayOptions mechanism:
- show: Field appears when conditions match
- hide: Field disappears when conditions match
- AND logic: All conditions must match
- OR logic: Any value matches
- Nested: Parent value controls child structure
Total: ~2,526 lines across 8 files
Based on analysis of 38,287 workflow updates and 9,835 essentials calls.
