Run a full architecture decision session for a given problem

Decomposes a large worldbuilding task into a sequenced plan with concrete steps, target files, verification criteria, and dependency order. Use before building a new civilization, designing a planet, or any task spanning more than 3 files. Triggers on "plan this", "break this down", "how should we approach", "build plan for", or "what is the sequence". Does NOT write content — produces the plan on

Runs a mandatory completion checklist before declaring any worldbuilding task finished. Catches missing frontmatter, broken cross-references, unlinked glossary terms, and deferral language. Use after writing any content, before reporting task complete, or when user says "is this done", "verify", "check my work", or "completion check". Does NOT write content — only verifies.

Writes new science files following academic prose standards: third-person voice, present tense for laws, in-universe terminology, consistent equation formatting, citation format. Use when creating new physics, chemistry, biology, or science files, expanding existing science content, or when user says "write", "create", "draft", "formalize", or "derive" in a science context. Does NOT write civiliza

Generates a WRITING.md file with YAML tokens for prose consistency — voice, tense, forbidden words, citation format, equation format, locked spellings — paired with usage rationale. Use when establishing prose standards, updating style rules, or when user says "WRITING.md", "style guide", "prose standards", "writing tokens", "voice", "style system", or "writing rules". Does NOT write content — gen

Writes new worldbuilding content: civilizations, characters, locations, factions, events, languages, or narrative elements. Use when creating new entries, expanding existing ones, or when user says "create", "write", "add", "flesh out", "build", or "expand" for any non-science content. Does NOT write science files — use /writing-science for that.

Generate properly formatted Markdown from unstructured notes, scratch text, transcripts, or rough drafts. Use when the user wants content rewritten into cleaner Markdown without inventing new information.

Apply when producing any markdown artifact for someone else (or future-you) to read — READMEs, analysis documents, Confluence pages, status reports, troubleshooting write-ups, skill content, conversation summaries, ticket descriptions, post-mortems, snapshots of system state, or any document that contains concrete current-state values. Defines the "snapshot + reproducer" rule (every static value m

Read, analyze, create, edit, repair, format, or validate spreadsheet files such as .xlsx, .xlsm, .csv, and .tsv. Use when the user provides a spreadsheet file, asks for native Excel output, needs formulas/pivots/financial-model formatting, or needs format-preserving edits. Do not use for ordinary Markdown tables or quick tabular prose unless spreadsheet file output is required.

Model product UI actions from user intent questions after a meaningful outcome, completion, created resource, imported data, uploaded file, synced integration, report, deployment, automation, review state, handoff, or workflow milestone. Use when deciding which actions to show, hide, group, name, prioritize, defer, or place across outcome, item, selection, continuation, navigation, recovery, and a
