What's on the bench.
Ab Test Setup
When the user wants to plan, design, or implement an A/B test or experiment. Also use when the user mentions "A/B test," "split test," "experiment," "test this change," "variant copy," "multivariate test," "hypothesis," "conversion experiment," "statistical significance," or "test this." For tracking implementation, see analytics-tracking.
Cs Markdown HTML Orchestrator
Density-first markdown-to-HTML converter. Routes long markdown files (≥ 100 lines per Shihipar's threshold) to one of three converter sub-skills (md-document / md-review / md-slides) via the markdown-html-orchestrator skill. Refuses below threshold or when the design-system isn't onboarded. Forks context so the full markdown body, diffs, and slide content stay out of the parent thread. Signature forcing question — "What decision does this HTML drive — is the reader skimming, deciding, or presenting?"
Cs Md Review
Convert a markdown PR writeup or code review (with ```diff blocks and > [!BLOCKER]/[!MAJOR]/[!MINOR]/[!NIT] severity callouts) into a single-file 2-column HTML review. Top jump-nav lists every finding by severity. Diff on the left, severity-tagged annotation cards on the right, mandatory named reviewer footer. Refuses without --reviewer (a code review must name a human) or if no diff hunks present.
Cs Md Document
Convert long-form markdown (specs, RFCs, reports, plans, explainers) into a single-file interactive HTML document. Runs the md-document pipeline (parser → renderer → injector) with the user's design-system tokens. Sticky TOC, search filter, code-copy buttons, scrollspy, WCAG-AA palette. Refuses input < 100 lines (Shihipar) or unfinished onboarding. Output is a single .html file (Google Fonts + Prism.js CDN as the only externals).
Cs Grill Markdown HTML
Matt-Pocock-style forcing-question grill for markdown-html conversions. Walks 5 cited-canon questions (purpose, line-count threshold, design-system onboarding, output path, doctype confidence) one at a time with a recommended answer. Run before /cs:markdown-html when you want clarity about what the HTML is for, not just a route to the closest sub-skill.
Cs Design System
Run the one-time markdown-html design-system onboarding wizard. Captures brand primary/accent (HEX) + heading/body Google Fonts + design style (editorial/technical/minimal/playful) + default output directory + syntax theme + TOC behavior + optional logo/company. WCAG-AA validates body-text contrast; refuses if it fails. Stores at ~/.config/markdown-html/design-system.json (or project-scoped with --scope project). Every converter reads this config via config_loader.py before rendering.
Md Review
Converts a markdown PR writeup or code review (one with ```diff fenced blocks and severity-tagged > [!BLOCKER]/[!MAJOR]/[!MINOR]/[!NIT] callouts) into a single-file 2-column HTML review — unified-diff on the left, severity-tagged annotation cards on the right, top jump-nav listing every finding, mandatory named reviewer footer. Triggers when the markdown-html-orchestrator classifies an input as REVIEW, or when invoked directly via /cs:md-review. Refuses without explicit --reviewer (a code review must name a human), refuses if no diff hunks present (route to md-document instead), and refuses to encode severity in color only (every badge ships color + icon + aria-label per WCAG 1.4.1). Use after orchestrator routing.
Md Document
Converts long-form markdown (specs, RFCs, reports, plans, explainers) into a single-file, lightly-interactive HTML document with sticky TOC, scrollspy, search filter, code-copy buttons, and design-system-driven brand tokens. Triggers when the markdown-html-orchestrator classifies an input as DOCUMENT, or when invoked directly via /cs:md-document. Reads the design-system config via config_loader.py and inlines the user's 12 derived CSS custom properties; refuses to render if onboarding hasn't run. Single-file output — Google Fonts + Prism.js CDN are the only externals; no framework runtime, no build step. Use after orchestrator routing or after design-system onboarding is confirmed.
Markdown HTML Orchestrator
Use when a user wants to convert any markdown file in their Claude project into a single-file, lightly-interactive HTML — long-form documents (specs, plans, RFCs, reports, explainers), code reviews with diffs and severity-tagged annotations, or slide decks. Triggers on "convert this markdown to HTML", "make this an HTML file", "turn this into an interactive document", "render this report as HTML", "PR writeup as HTML", "slides from this markdown". Forks context to route to one of three converter sub-skills (md-document, md-review, md-slides) based on a deterministic doctype classifier, after the user has run the design-system onboarding once. Refuses if input is under 100 lines (per Shihipar — markdown still wins below the threshold) or design-system isn't onboarded. Distinct from Anthropic's official Playground plugin (which is interactive prompt-tuning controls with sliders/knobs/prompt-copy-back) and from marketing/landing/ (which is a landing-page generator).
SaaS Metrics Coach
SaaS financial health advisor. Use when a user shares revenue or customer numbers, or mentions ARR, MRR, churn, LTV, CAC, NRR, or asks how their SaaS business is doing.
Business Investment Advisor
Business investment analysis and capital allocation advisor. Use when evaluating whether to invest in equipment, real estate, a new business, hiring, technology, or any capital expenditure. Also use for ROI calculations, IRR, NPV, payback period, build vs buy decisions, lease vs buy analysis, vendor evaluation, or deciding where to allocate limited budget for maximum return.
Cs Skill Author
Skill-author persona. Forcing-question interrogator before any new-skill commit. Runs Matt Pocock's 6-item review checklist as a 6-question gate. Refuses to accept skills with stale time-bound claims, vague descriptions, missing "Use when" triggers, or SKILL.md > 100 lines without progressive disclosure.
Cs Write A Skill
/cs:write-a-skill <name-or-description> — Author a new agent skill with Matt Pocock's 3-phase workflow (Gather → Draft → Review). Runs 6 review-checklist items + 3 validator tools as a gate. Use when starting a new skill in this repo.
Cs Workflow Architect
Workflow-architect persona. Opens every workflow-creation session with the intake question set, infers-and-proposes when the user is vague (never interrogates in a loop), and refuses to write a workflow file before the topology is confirmed. Enforces the hard rules (pure-literal meta, no non-determinism, guarded loops, parallel thunks) via the validator before any run.
Cs Workflow Build
/cs:workflow-build <task-description> — Design and write a deterministic Claude Code workflow (.js). Opens with intake questions, infers-and-proposes a topology when the request is vague, then scaffolds + validates the file. Use when building or running a custom Claude Code workflow.
Cs Scraping Architect
Use when the user wants to scrape a website, crawl docs, extract data from PDFs/Excel/CSV/HTML, parse an API response into a dataset, or debug a brittle scraping script. Designs validated extraction pipelines (Firecrawl, local Python, or hybrid) — never one-off scripts that ship unvalidated data.
Cs Scrape
Route, extract, and validate a scraping job (URL or local file) via the universal-scraping-architect skill — refuses to deliver unvalidated data.
Wiki Linter
Dispatched sub-agent that runs a periodic health check on an LLM Wiki vault. Runs mechanical checks via scripts (orphans, broken links, stale pages, missing frontmatter, duplicate titles, log gaps), does semantic checks (contradictions, stale claims, cross-reference gaps, concepts missing their own page), and produces a markdown report with suggested actions. Spawn weekly, after batch ingests, or when the user says "check the wiki" / "lint my wiki" / "audit the vault".
Wiki Librarian
Dispatched sub-agent that answers queries against an LLM Wiki vault. Reads index.md first, drills into 3-10 relevant pages across categories, synthesizes an answer with inline [[wikilink]] citations, and offers to file the answer back into the wiki as a new comparison or synthesis page. Spawn when the user asks a substantive question the wiki might answer, says "what does the wiki say about X", "compare A and B across my sources", or wants to explore a topic.
Wiki Ingestor
Dispatched sub-agent that ingests a new source into an LLM Wiki vault. Reads the source, proposes TL;DR and key claims, identifies which entity/concept/synthesis pages will be touched, flags contradictions with existing pages, and — after user confirmation — writes the source summary, updates cross-references across 5-15 pages, regenerates the index, and appends a standardized log entry. Spawn when the user says "ingest this", "add this paper/article/book to the wiki", or drops a file into raw/.
Wiki Lint
Run a health check on the LLM Wiki vault — mechanical checks (orphans, broken links, stale pages, missing frontmatter, log gap, duplicates) plus semantic checks (contradictions, cross-reference gaps, concepts missing their own page). Outputs a markdown report with suggested actions. Usage /wiki-lint [--stale-days N] [--log-gap-days N]
Wiki Ingest
Ingest a source file from raw/ into the LLM Wiki — read, discuss, write summary page, update cross-references across 5-15 pages, regenerate index, append to log. Usage /wiki-ingest <path-to-source>
Karpathy Reviewer
Reviews staged git changes against Karpathy's 4 coding principles. Runs complexity_checker on changed files, diff_surgeon on the diff, and produces a verdict with specific fix recommendations. Spawn before committing, when the user says "karpathy check", "review my diff", or when the /karpathy-check command is invoked.
Cs Handoff Author
Conversation-handoff author. Compacts the current session into a markdown handoff for a fresh agent. Tailors content to next-session focus. Refuses to duplicate content from PRDs/plans/ADRs/issues/commits — references them by path or URL instead. Recommends specific skills for the next session.
