parker2017code.github.io Agent Guidance

Scope

This repo is the root GitHub Pages redirect surface for parker2017code.github.io.
Keep it static and dependency-free unless the user explicitly changes the site purpose.
Preserve links to the TN12 proof lab and Kaspa Explained unless the user asks for different routing.

Codex is the primary agent for this repo. Use AGENTS.md as the durable instruction source.
Claude Code is secondary future compatibility. CLAUDE.md should import this file instead of carrying a separate rule set.
Start substantive work by checking git status --short and reading index.html.
Make the smallest coherent patch. Do not rewrite unrelated files or add dependencies without explicit approval.
Do not change GitHub Pages routing, canonical URLs, redirects, or site links without calling it out before the edit.
After edits, report changed files, commands run, verification result, commit hash, push target, and any remaining risk.
If a check fails, report the exact command and failure. Fix only failures related to the current task unless the user expands scope.
For UI/layout changes, verify desktop and mobile behavior and check link text for overflow.

Cheap check: python3 -m http.server 4178 --bind 127.0.0.1, then request / and confirm it returns 200 OK.
For route changes, inspect the rendered HTML and verify canonical and redirect targets.
