Staged build methodology for software projects: technical spike → design notes → build plan → stage-by-stage execution with professional-grade testing. Use when user says '/architect', 'new project', 'start a project', 'build this from scratch', wants to plan/build with structured methodology, or resumes an…

Extract knowledge, frameworks, and methodologies from a URL, file, video, article, or podcast. Use when user says '/eat', 'eat this', 'eat from', shares a URL/file for insights, or wants to learn from a video/article without reading the whole thing. NOT for summarization or news digests. Requires yt-dlp, whisper or…

Shifts the model from compliant executor to critical expert advisor. Identifies the domain, adopts top-tier expert perspective, understands the PURPOSE, returns ranked proposals to elevate the work. Works across UI/UX, copy, architecture, planning, code, strategy, branding. Invoke ONLY via /elevate — do NOT trigger on…
Skill Claude CodeCodex
Design judgment via design-director taste — reads design intent, assesses whether execution serves it, returns opinionated verdict with clear direction. Scales from one element to a whole app. Always judgment, never fixing. Invoke ONLY via /eye — do NOT trigger on 'review the design' or 'how does it look'.
Skill Claude CodeCodex
Testing infrastructure, coverage, and verified test quality for any project. Detects stack, installs testing ecosystem, audits untested critical paths, writes thorough tests weighted toward error paths, runs them, verifies via mutation testing. Use when user says '/fortify', 'add tests', 'set up testing', 'I need…
Skill Claude CodeCodex
Autonomous deep-work agent loop for driving projects forward. Each invocation: reads project state, applies critical expert thinking, executes one focused unit of work, persists to notebook + PROJECTSTATE.md. Sets up /loop cron on first run (default 10m). Three-tier confidence gate (GREEN/YELLOW/RED) blocks action…
Skill Claude CodeCodex
Context handoff for fresh sessions. Saves unsaved session knowledge to notebook, then produces a short orientation block to paste into a new chat. Use when user says '/memento', 'hand off context', 'prepare for fresh chat', 'save and brief', or before clearing context. NOT for: recovering context (use /notebook…

Pro mode — engineering standard enforcement. Forces senior-engineer behavior: root-cause discipline, layer awareness, current-gen API verification, blast-radius thinking, caller-first API design, no stubs, no sycophantic agreement, no unverified assumptions. Invoke via /prodev or 'prodev' — always run via Skill tool…
Skill Claude CodeCodex
Pre-build decision intelligence. Produces opinionated decision brief — the senior- consultant week-1 output before scope, stack, or approach are locked. Surfaces traps and edges, calibrated to project scope (prototype vs production vs enterprise). Use when user says '/recon', 'what to watch out for building X'…
Skill Claude CodeCodex
Obsessively thorough analysis. Three modes: build (find every issue in a codebase), intake (extract everything from a URL or reference), research (exhaustive investigation of a topic). Use when surface-level isn't enough and you need certainty nothing was missed. Triggers: '/scorched-earth', 'go scorched earth', 'find…
Skill Claude CodeCodex
Thorough codebase investigation that finds and fixes real problems. Maps architecture, scans every layer (structural, correctness, security, reliability, performance, hygiene), prioritized report with evidence, fix plan, executes collaboratively. A senior engineer doing a full review with authority to fix. Use when…
