AI Pull Review

Turns every PR into a conversation with Claude—flags bugs, reviews architecture, checks docs and estimates cost, then posts rich comments. Invited by Ready Tensor to showcase this project in the Agentic AI Innovation Challenge 2025. Multiple scan depths, already adopted by several orgs.

Code

Redlock K8s Laboratory

Blueprint that demonstrates Redlock-based distributed locking and cron scheduling across micro-services, with Docker-Compose & K8s manifests for local or cluster testing. Archived Jan 2025 but remains a solid reference for fault-tolerant job orchestration.

Repository Dispatch Action

Triggers repository_dispatch events so one workflow can fan-out to other repos, passing custom JSON payloads. Single-step usage (uses: diekotto/repository-dispatch@v1) and clear error handling/PAT support.

Code Digest Action

Generates an LLM-ready digest of any repo: metadata, directory map and per-file summary—ideal for onboarding or AI agents. Works via GH Action or npx @diekotto/code-digest; artifact retention and glob ignores built-in.

Sonar Scanner Analysis

Spins up SonarQube + Scanner inside CI, runs analysis and uploads a Markdown report artifact—no external server needed. Perfect for private or air-gapped repos; v1 delivers full quality-gate metrics and issue breakdowns.

Readme AI

AI-powered CLI that autogenerates rich, customizable README files from any repo; supports OpenAI, Anthropic, Gemini, Ollama, and even offline mode. My contributions: Shipped a GitHub-Action wrapper, added Spanish locale, and refactored the CLI to support larger Claude context windows while tightening tests.

Size Limit

Performance-budget tool for JavaScript that runs in CI, calculates real download & exec cost, and fails the build if a PR tips the budget; includes tree-shaking and time-based metrics. My contributions: Fixed PNPM-workspace resolution, added Vite example, and triaged bundle-size regressions across three major frameworks.
