Basilisk

Regenerate real product screenshots — either CLI screenshots (actual `basilisk check` output rendered in a Terminal window) or VS Code editor screenshots (the extension showing diagnostics, hover, quick-fix, activity panel). Use when the user asks to regenerate, update, or add marketing/docs screenshots. Requires a target argument, `cli` or `vsix`.

Creates a pull request with a well-structured description after verifying CI passes. Use when the user asks to submit, create, or open a pull request.

Work until acceptance criteria is met. Fix a bug/implement a feature using test-driven development (/fix-bug skill). Use when the user reports a bug, wants to implement a feature, describes unexpected behavior, wants to fix a defect, or says something is broken. Enforces a strict test-first workflow where a failing test must be written and verified before any fix is attempted.

Prepare the Basilisk codebase for CI. Reads the CI workflow, builds a checklist, then loops through fmt/clippy/build/test until every check passes. Use before submitting a PR or when the user wants to ensure CI will pass.

Uses deslop MCP to find the worst duplicate-code offenders in the repo and merge them. Loops until there are no major duplication issues left. Use when the user says "deduplicate", "find duplicates", "remove dead code", "DRY up", or "code dedup".

Audit spec/plan documents against the codebase. Ensures every spec section has implementing code, tests, and matching logic. Use when the user says "check specs", "spec audit", or "verify specs".

Upgrade all dependencies/packages to their latest versions for the detected language(s). Use when the user says "upgrade packages", "update dependencies", "bump versions", "update packages", or "upgrade deps".

Audits a website for SEO, AI search performance, structured data, mobile usability, broken links, and social media cards. Fixes issues found. Use when the user mentions "audit website", "SEO", "fix search ranking", "AI search", "structured data", "social media cards", or "website performance".
