The shared files are fetched from sneak/prompts dd4027b, with this repository's own entries after the shared content in .gitignore, .editorconfig and .dockerignore. Lint and tests are Dockerfile phases (golangci-lint v2.14.0, Debian Go 1.24.13) that the build stage depends on, and the Makefile targets call the script/ entrypoints. make fmt also formats Markdown with prettier. Fixes for the new lint findings: the auth cookie is always Secure, an IRC connection's relay goroutine stops when the connection closes, and repeated strings are constants. Model: opus-5-5
