Use when asked to run the Friday/weekly research digest or "Engineering Radar" that searches (Exa first, then SearXNG fallback), filters out anything previously included, ranks items by novelty/relevance/authority/impact, and produces a concise per-repo report with links. Also persists history/policy for future runs. - Author: Mistake Knot - Repository: mistakeknot/Derkhan - Version: 20260130202106 - Stars: 0 - Forks: 0 - Last Updated: 2026-02-06 - Source: https://github.com/mistakeknot/Derkhan - Web: https://mule.run/skillshub/@@mistakeknot/Derkhan~derkhan:20260130202106 --- --- name: derkhan description: Weekly engineering research radar for a set of active repos.

Also persists history/policy for future runs. --- # Derkhan Run the weekly Engineering Radar from the skill repo in `/projects/Derkhan`. ## Quick start Generate a report and append included items to history: ```bash node /projects/Derkhan/derkhan/scripts/run_weekly_radar.mjs ``` Dry-run (no history write): ```bash node /projects/Derkhan/derkhan/scripts/run_weekly_radar.mjs --dry-run ``` Limit to specific repos: ```bash node /projects/Derkhan/derkhan/scripts/run_weekly_radar.mjs --repos moltbot,Autarch ``` ## Behavior - Exa-first search via MCP (requires `mcporter` configured for `exa`). - SearXNG JSON fallback for repos with weak Exa coverage. - "Freshness" is defined as **new-since-last-included** (deduped by normalized URL) using `state/history.jsonl`. - Current scoring policy lives in `state/policy.json` (auto-created on first run). See `references/policy_schema.md`. ## Notes If Exa calls fail, verify: ```bash mcporter list exa # if missing: mcporter config add exa https://mcp.exa.ai/mcp ```
