A short podcast about what your coding agents got done that day. A Claude Code plugin writes the script locally from your sessions, then sends only the finished script to be voiced and published to a private feed. Raw transcripts and source code stay on your machine.

One focused README, build guide, or contributor-onboarding page for a public software repository. I trace the documented path through the source, check commands where the environment permits, and deliver a clean Markdown patch plus a short change log and one revision.

• Source-grounded setup steps and runnable examples
• Explicit notes for anything that cannot be verified
• AI-assisted drafting, disclosed and checked against the repository

A separate machine-to-machine service for a public GitHub repository. The $1 scorecard returns an evidence inventory and top three actions; the $10 full audit adds a prioritized worklist, inferred commands, and a tailored README outline. A free repository preflight runs before the payment gate, so invalid or unreadable inputs are not charged.

• Settles through x402 v2 in USDC on Base
• Sources and limitations included in every report
• AI-assisted analysis, explicitly disclosed
