▌
Video Script Writing · ericmjl bundle
Write and revise video scripts that hold viewer attention to the end and drive the desired action, grounded in retention and persuasion research (information-gap curiosity, Zeigarnik open loops, hook-concreteness studies, narrative transportation, speech-rate and scene-cut experiments). Use when the user asks for a video script, YouTube script, or explainer script; a founder, brand-story, or talking-head video; a landing-page, marketing, demo, or testimonial video; a video ad or VSL; or a short-form script (Shorts, Reels, TikTok). Also use when improving an existing script's hook, pacing, retention, or CTA, or when asked whether a script will hold attention. Covers hook tests, loop architecture, spoken-register drafting, production specs (cut rhythm, captions, words-per-minute bands, placement), and per-purpose playbooks with benchmarks.

Epistemic Resourcefulness · ericmjl
Breaks the cycle of repeated failed attempts by redirecting the agent to find the authoritative source of truth about a system's structure before trying again. Trigger this skill when: (1) the same command or query has failed 2+ times with variations, (2) output is garbled/binary and unreadable, (3) guessed field names, endpoints, or flags keep returning errors, (4) file/directory scanning is producing no useful signal. In short: if you're brute-forcing and it's not working, stop and use this skill.

Mempalace · ericmjl
Use the MemPalace CLI to persist, search, and manage AI memory across sessions. Triggers whenever the user asks to remember, recall, save, store, or retrieve information that should persist across conversations — including past decisions, preferences, facts about people or projects, conversation history, and any verbatim content the user wants preserved. Also triggers when the user mentions "palace", "wings", "rooms", "drawers", "knowledge graph", "AAAK", or when they want to search through historical context, traverse connections between topics, or check what their AI knows. Mirrors the MemPalace MCP server tools: each CLI command maps to an MCP tool with an equivalent trigger condition.

▌
Atomic Commits · ericmjl
Break unstaged or mixed changes into small, atomic, logical git commits with Conventional Commit messages.

Supports 6 video types: educational explainers, product launch demos, testimonial/social proof, avatar video overlays, data visualization dashboards, and lower third overlays. Each follows a 2-step workflow: research/scrape/analyze then design and animate with spring animations, SVG diagrams, and count-up effects. Requires the Remotion best practices skill (install with `npx skills add remotion-dev/skills`). Use when the user asks to create a Remotion video, explainer video, educational video, product demo video, testimonial video, video with animated overlays, data visualization video, animated dashboard, lower third, transparent overlay, short-form vertical video for mobile, or multi-product video from a website.

▌
PDF Form Filler · ericmjl bundle
Fill flat PDF forms that have NO fillable fields (school enrollment packets, medical intakes, waivers, government paperwork) and reuse a prior year's filled PDF as the source of answers. Requires a vision-language-model coding agent (renders pages to images and looks at them); there is no non-VLM fallback. Use when: the user asks to fill out / complete / fill in a PDF form, especially recurring yearly forms (enrollment, renewal, intake) where a previously filled copy exists; when pypdf reports zero AcroForm fields but the form has lines and labels; when the user says 'agent, fill this form for me'; when transplanting prior answers onto a new PDF template; when reproducing a scanned or drawn signature as vector ink from an old PDF; or when a filled form's text overlaps lines or labels and placement needs verification against rendered pixels.

▌
Coherent Writing · ericmjl bundle
Improve coherence in drafts through a five-pass sub-agent workflow: resolve cross-draft argument conflicts, fix within-paragraph logic (self-contradictions, sudden topic jumps, disconnects, unsignaled pivots), smooth section transitions, smooth paragraph-boundary transitions, and run a final coherence audit. Use when a user says things like 'make this coherent', 'tighten the flow', 'this feels choppy', 'this paragraph contradicts itself', 'fix the logic jumps inside this paragraph', 'the sentences don't connect', 'can you smooth transitions', or asks to revise prose in Markdown, notes, essays, blog posts, emails, or docs so ideas connect cleanly without adding new points.
