Build self-improving agent skills with cognee

## Quick overview A self-improving loop for agent skills, powered by the cognee Verified Node. When a skill's review scores below your threshold, it proposes a rewrite, and you approve the before/after diff before it's applied. No code required. ## How it works 1. Execute your workflow. 2. Set the demo inputs (skill name, dataset name, skill procedure markdown, review task text, and the score threshold). 3. Ingest the skill into cognee. 4. Cognee reviews the skill’s performance and returns a JSON with a score and gaps. 5. If the score is below the threshold, the workflow requests a cognee improvement proposal for the skill. 6. The workflow retrieves the full proposal from cognee and builds a human-readable before/after diff. 7. If the proposal is approved, the workflow applies the improvement in cognee, fetches the updated skill, and outputs the updated procedure and diff. ## Setup 1. Create a cognee API credential in n8n and use it in all cognee nodes (Ingest Skill, Review Skill, Propose Improvement, Get Proposal, Apply Improvement, Get Skill). Information for the credential (URL and API key) can be found in your Cognee Cloud account. 2. Update the skill parameters (skill_name, dataset_name, skill_markdown, task_text, score_threshold, and approved) to match your use case. 3. Ensure the referenced cognee dataset name exists so the skill can be stored and retrieved consistently.

Orchestrate multi-agent energy optimization with OpenAI GPT and Claude

## Quick Overview This workflow runs manually to orchestrate multi-agent analysis for a thermodynamic system, using OpenAI and Anthropic models to interpret sensor inputs, optimize energy usage, plan and execute tasks, validate results, and send an HTTP alert if validation fails. ## How it works 1. Starts when you manually trigger the workflow with initial system state, temperature, energy budget, and a task queue. 2. Uses OpenAI (GPT-5-mini) to analyze the provided sensor context, detect anomalies, and output structured sensor readings with confidence scores. 3. Uses OpenAI (GPT-5-mini) plus a calculator and custom energy-analysis code tool to compute efficiency/entropy metrics and propose an optimized energy allocation. 4. Uses OpenAI (GPT-5-mini) to build an execution plan and energy estimate for the queued tasks based on the optimized budget and sensor state. 5. Uses Anthropic (Claude Sonnet) to execute the planned task sequence within the estimated energy limit and return structured outcomes and actual energy usage. 6. Uses Anthropic (Claude Sonnet) to validate thermodynamic compliance by comparing planned vs. actual energy and generating recommendations. 7. If validation passes, compiles a final system report and returns the final system state; if validation fails, generates recalibration parameters and posts a JSON alert to an external webhook endpoint. ## Setup 1. Add credentials for OpenAI (Chat) and Anthropic (Chat) so the Perception, Energy Optimization, Planning, Execution, Validation, and Recalibration agents can run. 2. Replace the placeholder alert webhook URL in the HTTP Request step and configure HTTP Header Auth credentials for the target alerting endpoint. 3. Provide the required input fields on trigger (systemState, temperature, energyBudget, and taskQueue) or adjust the prompts to match your data structure. 4. If your execution step needs real environment context, add or connect a node that supplies the referenced environment data (the workflow currently references “Fetch Environment Data” but does not include it).

Optimize maritime routes and disruption response with OpenAI and Slack

## Quick Overview This workflow runs every 15 minutes to pull vessel telemetry/AIS data, enrich it with port and weather context, and use OpenAI to detect disruptions, simulate route alternatives, and generate an executive briefing that requires human approval before notifying teams in Slack. ## How it works 1. Runs every 15 minutes on a schedule. 2. Fetches fleet vessel telemetry and AIS data from a configured HTTP API. 3. Retrieves weather forecast and port congestion context for each vessel/route from a second HTTP API. 4. Uses OpenAI to analyze telemetry against historical baselines and classify any operational anomalies with severity and confidence. 5. Uses OpenAI to aggregate anomaly, weather, and port context into risk factors, urgency, and an action category. 6. Uses OpenAI to simulate 2–3 routing and speed options, estimating cost, emissions, fuel, duration, and weather risk, and selects a recommended route. 7. Generates an executive briefing with compliance and master-authority notes, pauses for human approval via an n8n form, and then posts the decision and recommendation to a Slack channel. ## Setup 1. Add OpenAI API credentials for the three OpenAI chat model steps. 2. Configure HTTP Header Auth credentials and replace the placeholder URLs and query parameters for your AIS/telemetry API and your weather/port API. 3. Ensure the upstream APIs return the fields referenced in the prompts (for example position, speed, fuel consumption, historical baselines, forecast, and port congestion). 4. Connect a Slack OAuth2 credential and select the target channel for posting the approved briefing. 5. Test the approval form step in n8n and confirm who will receive and complete approvals before enabling the workflow.
