Browser Trace
Capture a full DevTools-protocol trace of any browser automation — CDP firehose, screenshots, and DOM dumps — then bisect the stream into per-page searchable buckets. Use when the user wants to debug a failed run, audit network/console/DOM activity, attach a trace to an in-progress session, or feed structured per-page summaries back into an agent loop so its next iteration learns from the last on…
Rule Miner
Mine your Claude Code sessions and code-review history for the corrections you keep repeating, cluster them, adversarially verify each candidate, and distill the survivors into CLAUDE.md rules — or check that existing rules still hold. Uses a dynamic Workflow harness with one verifier per rule to avoid false positives. Use when the user says 'mine my sessions for rules', 'what corrections do I ke…
Miucr
Review code/diffs/PRs with the owned `miucr` CLI (miu-cr, a pure-Go AI code reviewer). Use when asked to review staged changes, a commit, a ref range, or a GitHub PR; to run/parse a gated review; compare reviewer quality with eval; to drive reviews over MCP; or to run the serve webhook/poll daemon or GitHub Action. Output is the stable `miucr.cli/v1` JSON envelope; parse it, don't grep prose.
Excalidraw
MANDATORY prerequisite for ALL Excalidraw MCP tool usage. Read BEFORE calling any Excalidraw tool (batch_create_elements, create_element, update_element, etc.). Without the sizing formulas, two-batch ordering (shapes-then-arrows), compact legends, domain styling presets, and write-check-review cycle in this skill, diagrams have invisible arrows, truncated text, and inconsistent colors. Use whenev…
Code Review
Review code with a sharp, encouraging voice — inline GitHub PR comments + a tight summary. Supports PR (default), pending changes, commit hash, and codebase modes. Encodes an opinionated review style: severity-prefixed, concise, actionable, no fluff.
Fastreact
Scaffold and build a full-stack web app: FastAPI backend (Python, uv, SQLModel, Postgres, Alembic, JWT + Google OAuth, boto3/S3) + React frontend (Vite, TypeScript, shadcn/ui + Tailwind, TanStack Router/Query/Table, Zod, Axios), wired with Docker Compose. Use this skill whenever the user wants to spin up, bootstrap, create, or design a new full-stack webapp; an API-first backend + SPA frontend; a…
Astro Airflow
Inspect and debug Airflow on Astronomer (Astro) deployments — fetch DAG runs, task instance logs, container logs, env vars, and deployment state without installing an MCP plugin. Use when the user mentions Astro/Astronomer, asks about DAG runs or task logs on staging/prod, says 'check the deployment', references `astro deployment`, `make airflow`, an Astro deployment ID, or a *.astronomer.run URL…
Scenario
Generate comprehensive edge cases and test scenarios by decomposing a feature or file across 12 risk dimensions. Use for pre-implementation risk discovery, QA planning, regression design, and exhaustive edge-case enumeration. Triggers: 'edge cases for X', 'what could break', 'test scenarios', 'QA plan', 'risk discovery', 'enumerate failure modes'.
Debug
Debug systematically across software, data pipelines, infrastructure, and analytics. Find root cause before fixing — for bugs, test failures, CI/CD breakage, K8s/Cloud incidents, dbt/Airflow pipeline failures, schema drift, freshness violations, dashboard wrong-numbers, and performance issues. Validates at every layer; verifies with fresh evidence before claiming done.
Opendesign
Generate polished single-file HTML design artifacts using the nexu-io/open-design catalog of production skills and brand-grade design systems. Use when the user asks to design, mock up, prototype, draft, build, or render a visual web artifact, chooses a brand/style direction, requests a deck/PPT, hero, section, component, marketing page, dashboard, email, doc page, or GitHub README/repo banner. A…
Scout
Fast, parallel codebase scouting across software, data-engineering, devops, and analytics surfaces. Use to locate files, dbt models, dashboards, IaC, pipeline DAGs, K8s manifests, secrets, and CI workflows before changes. Supports internal (Explore subagents) and external (Gemini/OpenCode CLI) modes.
Brainstorm
Explore the solution space when the path isn't obvious — invent options, stress-test them, pick one. Use for architecture decisions, design tradeoffs, ambiguous problems, and when the user asks 'how should I approach X?'. Default produces a decision brief; pass `--quick` for chat-only, `--deep` for multi-round adversarial debate with full design doc.
Gws
Manage Google Workspace from the CLI: Gmail, Drive, Calendar, Sheets, Docs, Tasks, Chat, and Workspace Admin for vanducng.dev via the official `gws` command. Use when the user mentions gmail, drive, calendar, sheets, docs, workspace, gws, vanducng.dev, email, files, events, or Workspace users/groups.

My curated Go stack reference — opinionated guide to Sam Berthe's libraries (lo Lodash helpers, oops structured errors, do v2 DI, mo monads, slog logging ecosystem, hot in-memory cache pre-1.0, ro reactive streams pre-1.0). Use when writing or reviewing Go code that imports github.com/samber/*, when deciding between these libraries and the stdlib, when adopting or upgrading any of them, or when s…
Devlog
Turn recent engineering work into build-in-public devlogs for X/Twitter. Use when the user asks to draft or write a devlog/post, create a vault post and cover, start today's dev log on x.com, publish a ship/debug/lesson thread, or turn recent commits into a public update.
Cook
Execute a plan (or a small task) phase-by-phase: implement → verify → test → review → update status. Use after `vd:plan` to ship the plan, or directly for tight tasks (`--quick`). Default stops at review gates between phases; pass `--auto` to run straight through, `--quick` for sub-plan tasks, `--tdd` for tests-first.

Marketing brand-asset generation (raster images via AI): logo design (55 styles, 30 palettes, 25 industries), corporate identity / CIP mockups (50 deliverables — business card, letterhead, signage, packaging, apparel), banner design (22 styles, social/ads/web/print), SVG icon design (15 styles), social photos (multi-platform), and model-agnostic poster prompts. Default image engine is Codex gpt-i…
Gopass
Retrieve credentials (API keys, tokens, passwords) from the local gopass password store. Use when a task needs a secret that the user has stored in gopass — instead of asking the user to paste it, search the store and read the value with `gopass find` / `gopass show -o`. Also covers inserting, generating, listing, searching, syncing, and TOTP.
Journal
Write a focused engineering journal entry — retrospective on what just shipped or post-mortem on what just broke. Use after vd:ship, vd:cook, or right after an incident while context is fresh. Saves to the injected Journals path (personal dev log, not project docs).

Threat-modeled security audit using STRIDE + OWASP (incl. the OWASP LLM Top-10 lens for AI/agent code), scanning code from multiple attacker perspectives, with optional red-team discovery loop and an autoresearch-style fix loop. Use for defensive security review, vulnerability discovery, threat modeling, prompt-injection / LLM security, and authorized remediation. Triggers: 'security audit', 'STR…
Research
Deep technical research with multi-option evaluation. Use for technology selection, architecture decisions, library/framework comparison, security and performance analysis. Default mode is thorough; pass `--deep` for exhaustive coverage with expanded comparison matrices and edge-case analysis.
Docs
Manage project documentation in ./docs/ — initialize, update, check, or record an ADR (architecture decision record). Canonical set is intentionally small: development guidelines, system architecture, tech stack, deployment; plus append-only decision history under docs/decisions/. Scouts the codebase, delegates writing to the docs-manager subagent (or stays inline with --inline).
Dbdesign
Design and review production database schemas, data models, ERDs, migration plans, and storage patterns. Use for OLTP schema design, OLAP/star-schema modeling, fact/dimension tables, indexes, constraints, partitioning, multi-tenant data models, CSV/JSON-to-table design, schema review, migration risk review, and database design documents across PostgreSQL, MySQL, SQLite/D1, BigQuery, and MongoDB.…
Apidesign
Design stable, hard-to-misuse interfaces — REST/GraphQL endpoints, module boundaries, type contracts, component props, anything where one piece of code talks to another. Use at design time, before implementing the surface. Triggers: 'design this API', 'API contract', 'endpoint design', 'module boundary', 'interface design', 'should this be one endpoint or two', 'how should this API look'.
Plan
Turn a chosen approach into a phased implementation plan with concrete steps, file changes, and success criteria. Use after `vd:brainstorm` (or any decided design) when you need to sequence the work before building. Default produces plan.md + phase files; pass `--quick` for a single-file plan, `--deep` for research dispatch + red-team review.
Py2go
Migrate Python projects to idiomatic Go end-to-end. Branches into 6 project-type playbooks (CLI, TUI, HTTP backend, data pipeline, async worker, library) with the right stack defaults (Gin, pgx, sqlc, slog, etc.) and pinned library versions. Default strategy: LLM module-by-module rewrite with golden-file parity tests; --strangler for live-traffic gradual cutover; --spec-first for OpenAPI/proto-dr…
Devops
Deployment and infrastructure operations. Use when writing or debugging a Dockerfile, docker build/run, docker compose; running terraform plan/apply/destroy or editing .tf files and modules; using kubectl, debugging pods (CrashLoopBackOff, ImagePullBackOff, OOMKilled), applying manifests, or writing Helm charts; deploying to GKE/EKS/AKS, Cloud Run, or App Engine; GitOps with Argo CD or Flux; writ…
Codex Workflow
Run deterministic multi-step agent workflows in Codex — fan-out, parallel, schema-validated structured output — via the codex-workflow MCP orchestrator (run_workflow), with native in-chat fallbacks. Use when you want Claude-Code-Workflow-style orchestration in Codex: 'run a workflow', 'fan out subagents', 'review each file in parallel', 'orchestrate these steps'. Triggers: 'codex-workflow', 'run_…
File Browser
Local HTTP server that renders markdown, code, text, JSON, CSV/TSV/XLSX tables, HTML, PDF, images, video, and audio in the browser. Persistent left tree sidebar with vim keybindings (j/k/h/l/gg/G/Enter/o), filter (/), theme toggle (T), and folder open/collapse persistence per tab. Markdown dispatches to a novel-theme reader (Mermaid, plan nav, ToC scroll-spy); code/text dispatches to a highlight.…
Optimize Loop
Autonomous metric-optimization loop — run N bounded iterations against a mechanical metric, commit each attempt, auto keep/discard on the number, revert regressions. Use to improve a measurable metric: test coverage, bundle size, lint/type-error count, p95 latency, LOC. Triggers: 'drive coverage up', 'reduce bundle size', 'get lint errors to zero', 'optimize <metric> over iterations', 'keep/disca…
Diagram
Generate modern reviewable diagrams (system architecture, workflow, data flow, sequence, ER, state-machine, C4) via OpenRouter image-gen or LLM-emitted SVG. Auto-classifies diagram type from prompt; --type to override. Default scratch output goes to the resolved workbench visuals path; --versioned writes git-trackable specs and variants under docs/diagrams/.
Herd Worktree
Set up an isolated git worktree for a Laravel project served by Laravel Herd (Pro-aware). Composes vd:worktree for the worktree/.env/port mechanics, then adds the Herd layer: link + scheme-correct site (HTTPS via herd secure when the source is secured), .env rewrite (APP_URL, SESSION_DOMAIN, Sanctum — only when present), opt-in per-worktree database isolation, Vite TLS/CORS, then hands finishing…

Granular git operations with conventional commits — stage, commit, push, PR, merge. Auto-splits commits by type/scope, blocks on secrets, delegates verbose work to git-manager subagent. Use when you want explicit control; for full ship-it pipeline use vd:ship.
Fix
Fix issues end-to-end across data pipelines (Airflow/dbt), app stack (backend/frontend), and infra (CI/CD, Terraform, K8s). Scout → diagnose → apply at root cause → verify with fresh evidence → add regression guard. Use for failing DAGs, dbt test failures, 5xx, UI regressions, GH Actions failures, terraform drift, CrashLoopBackOff, lint/type errors. Stops after 3 failed attempts to question archi…
Cnb Ds Eda
Build evidence-backed exploratory analysis and GitHub-renderable notebook reports in `/Users/vanducng/git/work/cnb/cnb-ds-eda`. Use when the user asks for CNB EDA notebooks, Snowflake-backed analysis, Retell or Transfer AI investigations, data-contract-derived report logic, notebook refreshes, or report artifacts under `notebooks/`.
Copywriting
Conversion copywriting formulas, headline templates, email copy patterns, landing page structures, CTA optimization, and writing style extraction. Use for high-converting copy, headlines, email campaigns, landing pages, social posts, product copy, CTA variants, or applying custom writing styles from an assets/writing-styles directory.
Computer Clean
Audit and reclaim disk space on macOS. Discovers cache hogs, dev caches, dead app data, old Downloads, dup installers, and obsolete container/VM images. Use when user says 'clean disk', 'free up space', 'computer-clean', 'cleanup mac', 'disk full', or shows ≥85% disk usage.
Plan Audit
Audit a vd:plan output for gaps, inconsistencies, missing scaffolding, and codebase drift using an independent clean-context subagent. Use after vd:plan (or any time after manual edits to phase files) when stakes warrant verification beyond same-context red-team. Auto-fires at end of vd:plan --deep.
Agent Browser
Drive web pages with the agent-browser CLI (Playwright engine) — snapshot with @e refs, fill/click, video recording, network mocking, persistent --profile and storage-state auth. The alternative driver to vd:browser for when you need WebM recordings of a flow, request mocking/blocking, device emulation, or Playwright wait semantics. Use when the user says "agent-browser", "record a video of the f…
Ship
Ship a feature branch end-to-end: merge target → test → review → version/changelog → commit → push → PR, then drive CI green and hand off the PR. Use when ready to land a branch on main/master (official) or dev/beta (beta). Merge is opt-in — a bare ship stops at a green PR; it merges only with --auto or --merge. Stops on test failures, critical review issues, or major version bumps.
Auto Loop
Drive a Claude Code session toward a verifiable goal until done or a hard cap fires — autonomous loop, no user intervention. Use for refactor batches, test-coverage runs, migration loops where success is a check command (tests, lint, custom predicate) plus a fresh-context audit. Hosts the loop intra-session via Stop hook with two-vote completion gate; supports optional Codex /goal delegation.
