About this codebase
`last30days-skill` is a codebase documentation engine that powers `/last30days`: it ingests user prompts plus source evidence (Reddit, X, arXiv, Techmeme, Digg, Trustpilot, and more), runs an indexing + relevance-scored extraction pipeline, and outputs a renderer-ready “brief” that’s served through an MCP server and consumed by editor/agent hosts as an OpenAI Codex-native plugin. In practice, users invoke it in an agent or editor (e.g., `/last30days Peter Steinberger`) and the system returns meeting-ready intelligence grounded in community-ranked sources.

Code health
This codebase scores 6.3 out of 10 for code health, which we rate fair. It also scores maintainability 6.7 and static performance 9.5 out of 10. The three are scored separately and never blended into one number. Risk is concentrated, as it usually is: 59 of 434 files are git hotspots, and they average 4.1 — which is where the fixes pay off most.

How mvanhorn/last30days-skill works
User prompts enter through the skill scripts in skills/last30days/scripts, which provide command dispatch, onboarding, and local persistence setup. Source-specific collectors and shared engine components in skills/last30days/scripts/lib shape queries, apply relevance rules, handle dates, and support HTTP, logging, schemas, and rendering. skills/last30days/scripts/lib/pipeline.py coordinates the indexing and extraction flow. skills/last30days/scripts/lib/render.py turns collected evidence into a renderer-ready brief. skills/last30days/scripts/lib/env.py manages environment-related setup, while skills/last30days/scripts/lib/youtube_yt.py handles YouTube collection. The Go entry point mcp/cmd/last30days-pp-mcp/main.go registers MCP tools, and mcp/internal/engine/run.go provides the engine runtime used by the MCP server.
AI agent skill that researches any topic across Reddit, X, YouTube, HN, Polymarket, and the web - then synthesizes a grounded summary This page is a map of the mvanhorn/last30days-skill repository, written primarily in Python, rebuilt from the source each time it is indexed. Repowise parses every symbol, computes a dependency graph, scores per-file code health from complexity, duplication, test coverage and churn, mines git history for hotspots and ownership, and lifts the architectural decisions into documentation you can read here or query through MCP.
The codebase has 434 files and 9,497 symbols in 4 modules, led by Python, Go and Shell. Code health is 6.3 out of 10, rated fair.
