What it does

Uist Supplementary is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when producing the video figure and supplementary materials for a UIST submission — treating the 3-minute video as near-mandatory evidence in a demo-culture venue, scripting it around claims, meeting the 1080p/4K H.264 spec, anonymizing frames and audio, and deciding what else ships alongside the PDF.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Documents & Office. The repository describes itself as: Journal-specific Claude Code/Codex skill packs covering mainstream journals — AER, QJE, Nature, Cell, 管理世界, 经济研究 & 200+ more — your fast track to getting published. | 覆盖主流期刊的… The licence is MIT.

When your agent uses it

  • Scripting it around claims
  • Meeting the 1080p/4K H.264 spec
  • Anonymizing frames and audio
  • Deciding what else ships alongside the PDF

Example prompts

  • “/uist-supplementary”

What it can do on your machine

Read from SKILL.md and the folder at commit 932eb23. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • ffprobe
    • ffmpeg

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Uist Supplementary loads about 1.5k tokens when it runs. Until then it costs about 81 tokens; SKILL.md has 598 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~81
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use when producing the video figure and supplementary materials for a UIST submission — treating the 3-minute video as near-mandatory evidence in a demo-culture venue, scripting it around claims, meeting the 1080p/4K H.264 spec, anonymizing frames and audio, and deciding what else ships alongside the PDF.

UIST Supplementary

At most venues supplementary material is an appendix annex. At UIST the central supplementary object is the video figure, and it is closer to a second first-page than to an attachment: reviewers at a venue built on demo culture watch it early, form their belief about whether the system is real, and read the paper through that belief. The 2026 Author Guide calls it optional but highly encouraged; for any paper whose contribution moves, responds, or renders, treat "optional" as theoretical.

The 2026 video spec (verified 2026-07-08)

PropertyRequirement
LengthAt most 3 minutes
Resolution1080p (1920×1080) or 4K (3840×2160)
Container/codecMP4, H.264
AnonymitySame standard as the paper — frames, audio, and filenames
RoleHelps reviewers evaluate the submission

Captions/subtitles make the video robust to reviewers watching without audio and prefigure the accessibility work required at camera-ready (see uist-camera-ready).

Script the video around claims, not features

Build the shot list from the paper's contribution list — the video is the visual twin of uist-experiments' claim-evidence audit:

text
0:00-0:15  Problem in one shot: the interaction that is impossible/painful today
0:15-0:45  The artifact working, uncut, on the core capability (claim C1)
0:45-1:45  C2..Cn each demonstrated in one continuous take
1:45-2:30  Breadth: 3-4 application vignettes, a few seconds each
2:30-3:00  Envelope honesty: one edge condition, then the closing capability shot

Production rules that pay at review time:

  • Real time by default. Label any speed change on screen. Nothing erodes trust faster than suspecting a cut hides recognition latency.
  • Uncut interaction loops for the core claim: input and response in the same frame — screen-plus-hands, or picture-in-picture.
  • No staged reactions or marketing gloss; reviewers are builders, and polish that outruns the paper's measurements reads as concealment.
  • Consistency audit: every capability shown must be measured or demonstrated in the paper; every headline claim in the paper should be visible in the video.

Narration and captions

The soundtrack is argument, not atmosphere:

  • Narrate what the viewer is seeing and why it is hard, in the paper's vocabulary — the video and the PDF should share their key terms so reviewers can cross-reference without translation.
  • One sentence of narration per shot; silence over a working demo is stronger than filler ("as you can see, the system works well" convinces no one).
  • On-screen labels for condition changes ("2× speed", "different user", "outdoor lighting") — reviewers treat unlabeled cuts as concealment.
  • Captions verbatim from narration, timed to shots; they are how the video reads in a quiet review session and they seed the accessibility work that camera-ready requires anyway.
  • No music under narration, no title-card branding that could hint at a lab's house style.

Editing checklist before the spec check

text
[ ] every cut between input and response is labeled or absent
[ ] each claim shot runs uncut for at least one full interaction loop
[ ] condition labels present for speed/user/environment changes
[ ] captions complete, spell-checked, synchronized
[ ] first 20 seconds show the artifact working (reviewers may not finish)
[ ] final frame is the capability, not a logo

Anonymizing moving pictures

Video leaks identity through channels PDFs do not have:

  • Frames: faces, badges, lab posters, whiteboards, distinctive rooms, license plates through windows.
  • Audio: narrators saying "at our lab in...", recognizable voices; re-record or synthesize narration if needed.
  • Overlays and assets: watermarks, usernames in menu bars, OS accounts, project names in window titles.
  • Metadata: camera serials and GPS in the container.
bash
# Spec + metadata check on the exact upload file
ffprobe -v error -show_entries format=duration,size:stream=codec_name,width,height video.mp4
ffmpeg -i video.mp4 -map_metadata -1 -c copy video_clean.mp4   # strip container metadata

Beyond the video: what else to ship

  • Anonymized overlap copy — required in 2026 when a prior submission of yours overlaps heavily (see uist-submission); this is a UIST-specific obligation.
  • Code, firmware, and design files — reviewed as evidence of reality; package them runnable-in-five-minutes (see uist-artifact-evaluation).
  • Extended results — full benchmark grids, study instruments, codebooks; but anything decision-critical belongs in the PDF's appendix, since supplementary reading is at reviewer discretion.
  • A manifest — one README listing every file and which paper section it backs; unlabeled archives simply do not get opened.

Scheduling reality

Video production consumes the same final two weeks as paper polish and cannot start before the system is stable. Book the capture rig, the edit pass, the caption pass, and the compression/verification pass as calendar items at feature freeze (uist-workflow), and dry-run the export pipeline early — render failures at 2 am AoE are a recurring UIST deadline story.

Output format

text
[Video status] scripted / shot / edited / spec-verified / anonymized
[Claim coverage] video shows <k>/<n> contribution claims; gaps: <list>
[Spec check] duration · resolution · codec · captions · metadata
[Supplement set] <files + the section each supports>
[Risk] <the single most likely late failure in the pipeline>
