Landing Page Copy (AIDA) + Edit
v1.0.1runcastle
A mixed-provider copy pipeline: a Claude Code writer turns your product brief into full AIDA-structured landing page copy, then a Codex editor cuts fluff, makes claims concrete, and tightens headlines on the same warm branch, looping until it ships.
Launch Thread Writer + Critic
v1.0.1runcastle
A Claude Code writer drafts an X/Twitter launch thread from your product brief, then a Codex critic tears it apart post-by-post — hook, clarity, specificity, CTA — rewriting the weak posts on the same warm branch until the thread is ready to ship.
Literature Review Builder
v1.0.1runcastle
Reads a sources.md list of papers, fetches each one, and builds a structured literature review — per-source summary of question, method, finding, and limitation — then synthesizes the themes, disagreements, and open gaps across the whole set.
Newsletter Digest Builder
v1.0.1runcastle
Reads a links.md list of URLs, fetches each one inside the sandbox, and has a Claude Code agent write a ready-to-send newsletter digest — a tight 2–3 sentence summary of every link, why it matters to your readers, and the source link, all assembled into a single markdown issue.
Blog Post Pipeline
v1.0.1runcastle
Turn a single topic into a publish-ready blog post through three sequential Claude Code passes on one warm branch: an Opus strategist outlines the angle and keywords, a Sonnet writer drafts the full post, and an Opus editor tightens the prose and optimises it for search.
Refactor with Adversarial Review
v1.0.1runcastle
A Claude Code agent performs a refactor, a hard `npm test` gate proves nothing broke, then a Codex reviewer adversarially audits the change on the same warm branch — hunting regressions, weak tests, and shortcuts — fixing and looping until it approves.
Deep Research Report
v1.0.1runcastle
Fans out a searcher per sub-question to fetch and note public web sources, then an Opus synthesizer writes a fully cited report, then a Codex fact-checker adversarially verifies every claim against the notes and loops until the report holds up.
