Deploy or change a Cloudflare Worker with cf. Review config, preflight, build and dry-run; show the target and change, obtain explicit approval, deploy and verify. Covers versions, secrets, rollback and named modes.
Design and write Cloudflare Durable Objects. SQLite storage, RPC methods, WebSocket hibernation, alarms, class lifecycle (exports or migrations), and testing. Use for stateful coordination, rooms, per-user state, counters, rate limiters.
Migrate a Cloudflare Pages project to Workers with static assets. Convert config, handle _worker.js and Pages Functions, move authored commands to cf, validate with a dry run. Use when a project has pages_build_output_dir or uses wrangler pages deploy.
Use Cloudflare KV, R2 and D1 from a Worker. Binding config, Worker code, cf commands, local vs remote data, D1 migrations. Use when adding or changing storage bindings or schemas.
Build, configure and test a Cloudflare Worker locally with cf (cloudflare.config.ts, typed bindings, static assets, cf dev, vitest). Use when creating or changing Worker code or configuration. Does not deploy; use cloudflare-deploy for that.
Triage and draft GitHub issues with the GitHub MCP tools - search for duplicates, classify and prioritize, and draft a well-formed new issue for the user to approve. Read-only until the user approves a specific create or label action. Use for "triage these…
Review a GitHub pull request with the GitHub MCP tools - read the description, diff, checks and existing discussion, then report findings in chat. Posts nothing to GitHub unless the user asks for that exact post and approves the text. Use for "review this…
Triage Linear issues and claim work with the Linear MCP tools - find the triage queue or your assigned work, check for duplicates and existing owners, set team/priority/labels, and claim an issue (assign to me, move to In Progress) only after confirming…
Write an evidence-based status update from Linear data - summarize what shipped, what is in progress, what is blocked or stale for a project, cycle, or a person's issues, and optionally post it as a Linear project status update after the user approves the…
Audit a page or UI against WCAG 2.2 AA. Runs a static HTML scanner and a contrast calculator, then walks the manual keyboard, zoom, screen-reader-name and form checks the tools cannot do, and reports findings with the criterion, evidence, fix and how to…
Critique a user interface (screenshot, running page, HTML/CSS, mockup or description) and return severity-ranked findings with evidence and a concrete fix for each. Use when the user asks for design feedback, a UI review, "what's wrong with this screen", or a…
Review and rewrite the words in a user interface (buttons, labels, errors, empty states, confirmations, onboarding, notifications) for clarity, tone and consistency. Use when the user asks for UX writing feedback, microcopy, error messages, button text, or a…
Set up a bounded iterate-until-done run with the loop plugin's /loop command. Use when the user wants the same task retried or refined across several replies until a check passes, such as "keep going until the tests pass" or "do this up to 5 times".
Fan six specialist reviewers (general correctness, silent failures, type design, test gaps, comment accuracy, simplification) out over the current diff, a branch, or a PR in parallel, then merge their findings into one deduplicated, ranked report. Use for a…
Write a clear git commit message from the staged changes. Use when the user asks for a commit message, or to summarize what they are about to commit.
Sample skill that proves a DeepSeek Harness bundle imported into Codewhale. Use only when the user is trying the dsh-sample plugin.
Deploy a project to Vercel safely. Preview versus production, project linking, vercel CLI and Git-based flows, promote, rollback. Never deploys without the user's explicit approval. Use for any request to deploy, ship, publish, promote or roll back on Vercel.
Manage Vercel environment variables safely. Environments, vercel env ls/add/update/rm/pull/run, sensitive variables, NEXT_PUBLIC exposure, when changes take effect. Use when adding, rotating, auditing or pulling Vercel env vars.
Debug a failing Vercel deployment or a misbehaving production site. Read build logs and runtime logs with vercel inspect and vercel logs, reproduce builds locally, find missing env vars and Node or output-directory mistakes. Read-only investigation.
Configure a Next.js app for Vercel. next.config versus vercel.json, proxy (renamed from middleware in Next.js 16), images, redirects and headers, function duration and region, caching and static export pitfalls, and local verification. Use when editing…
Build a self-contained web page, dashboard, prototype, calculator or small interactive tool as ONE HTML file (plain HTML/CSS/JS, or React plus Tailwind bundled into a single file), check it, and preview it locally. Use when the user wants a page they can…
Operate desktop apps and isolated browsers on registered computers. Use for tasks that require an app interface, accessibility, screenshots or recording. Use Chromewhale for the user's signed-in Chrome.
Read and act on selected Chrome tabs and frames — their real browser, their logged-in sessions. Use for questions about the current page, filling a form the user is on, following a link they mentioned, or checking what a site actually renders. Not for…
Explain an unfamiliar repository, find where to make a change, and maintain source-cited documentation. Use for repo onboarding, wiki questions, documentation impact, or updating and sharing a WhaleWiki.
Analyze one recorded agent session the way the Whalesong instrument does — signal shape first, computed findings second, exact evidence rows last. Use when the user asks what a session did, why it stalled, looped, errored, or burned tokens.
Render a recorded agent session to audio with Whalesong's deterministic synthesizer and interpret it — hear a loop, a stall, an error storm, or the difference between two runs. Use when the user wants to feel a session's shape, compare runs by ear, or present…
Quantify periodicity in a recorded agent session — dominant onset period in seconds, spectral entropy, autocorrelation lag. Use to prove a poll loop, measure how metronomic retries are, compare cadence between runs, or window into one suspicious stretch.
Sweep recent sessions across every agent CLI recorded in Whalesong and surface the ones worth a look — errors, runaway loops, token blowouts, stalled gaps. Use for "what have my agents been doing", morning reviews, or finding the session that went wrong.
Attach review scores to recorded Whalesong traces and build comparison pairs — mark a session good/bad/regressed, then diff two runs deterministically. Use when evaluating agent changes, reviewing a run after the fact, or building a small eval set.
Look up current Cloudflare documentation (Workers, Pages, KV, R2, D1, Queues, DNS, WAF, platform APIs) through Cloudflare's official remote MCP server. Use when answering Cloudflare questions or writing Cloudflare config.
