lower-thirds

lower-thirds is a skill for Claude Code from 2233admin/design-pipeline. It costs 109 tokens per session (2,497 once invoked), scanned A, a copy of lower-thirds, MIT.

Guidance for creating lower thirds: the name and role captions placed near the bottom of a video frame. It covers readable text, safe placement, entrance and exit motion, and reusable templates.

In plain words
What is it for?
Use it for interviews, panels, broadcasts, podcasts, webinars, and applying one name-and-role design to many clips.
Why use it?
It helps produce consistent speaker labels and titles that remain readable without distracting from the video.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

lower-thirds scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Lower Thirds

Build a clean, branded lower third — the name/role caption that lives in the bottom band of the frame — that animates in, holds long enough to read, and exits without stealing the shot. The craft is restraint: a crisp reveal, a strong type hierarchy, correct safe-area placement, and one template that drives a whole roster of speakers.

When to use

  • Speaker/interview name tags, panel rosters, talking-head captions.
  • Broadcast-style titles, news straps, podcast/webinar name plates.
  • Templating one design across a list of names/titles → many clips (the payoff).

Anatomy

A lower third is two text lines plus a graphic bed, placed in the lower band:

Element Role Type treatment
Name (primary) Who Largest, heaviest, tightest tracking
Role/title (secondary) What/where ~45–60% of name size, lighter weight, often a brand accent color
Bar / panel / accent Reads against any background Solid or 70–85% opacity; an accent rule ties to brand

Keep it to two lines. A name line + role line is the whole job — extra lines erode the hierarchy and crowd the safe area.

Three rules that prevent cheap-looking titles

  1. Never hard-cut a title on or off. A bare appear/disappear reads as a mistake. Even a 12-frame fade or slide makes it feel produced.
  2. Stagger, don't slam. Animate the bar first, then the name, then the role, each offset by 3–6 frames. Everything arriving at once feels flat; a short cascade feels designed.
  3. Hold long enough to read twice. Roughly 3–5s on screen (read it aloud twice). Too short and it's missed; too long and it nags. Animate in/out, never mid-segment.

Enter & exit animations

Pick one motion language and reuse it. The most reliable, premium-reading reveals:

Reveal Feel How
Slide + fade Clean, default Translate in ~24–40px while fading; ease-out on enter
Wipe bar Broadcast A bar scales/sweeps in (scaleX/clip), text fades behind it
Mask reveal Premium Clip text to a moving rectangle so letters "wipe on"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
