You say

“Use Release Timeline Feed to show real version, date and change differences from a traceable source. Supply pinned repository references; the Skill rejects illustrative release history.”

After installing, say something like this to your agent with your own topic and assets. It asks only for what is missing.

FAQ

Do I need an account?

Yes. Members Skills install from a signed-in FeedSkills account with an active Founding Membership.

What does it cost to run?

The Skill is included with Founding Membership. It needs the tools listed under “You will need”. Any voice, model or media service you choose bills you directly; FeedSkills does not include provider credits.

Can I use the videos commercially?

Videos you make are yours to use, including commercially. The Skill package is licensed as: FeedSkills Source-Available 1.0 · bundled fonts retain Apache-2.0 or SIL OFL 1.1. Fonts, music, footage and services you add keep their own terms.

Which agents does it work with?

Agents that read SKILL.md files, such as Codex or Claude Code. What FeedSkills has actually tested is listed under Tested scope below.

Tested scope

Version: 0.1.0
Acceptance: This version has a recorded acceptance entry.
Tested: Two 20.4-second 1080x1920 / 30 fps English example films and one single-scene edit were rendered with burned captions, measured DOM layouts and full-stream checks; both themes recorded 18 passes, 1 warning and 0 fails. The edit rerendered path-close and reused the other five scenes with native-frame proof; package check/create and DOM guard passed. Real-phone review and customer adoption remain separate.
Runs on: Claude Code · Codex · macOS · Node.js 22+ · FFmpeg

Details

Release Timeline Feed

Release Timeline Feed is a Members Skill for tracing real version and date differences to pinned repository evidence. It presents an evidence rail or ledger, not an invented release announcement.

Reviewed A/B previews

Theme A video · cover (absolute video)
Theme B video · cover (absolute video)

Both examples use six stable timeline scenes with measured layout, burned captions and SRT. Every history entry carries a semantic version, ISO date, change, verification state and pinned source reference; the local edit changes one closing scene.

Install and use

Install the approved member package with:

npx --yes --package=https://feedskills.com/downloads/feedskills-0.3.6.tgz feedskills install release-timeline-feed --agent codex

Copy examples/theme-a.json or examples/theme-b.json into a project outside the installed Skill. Supply two to five chronological history entries per scene and verify each pinned source before rendering. Run project.mjs doctor, project.mjs check, project.mjs create and the generated render entry. Use local Kokoro for narration; node render.mjs --no-voice is an explicit silent export.

For a single-scene revision, keep scene ids and durations stable, edit one copied history or caption scene, rerun the render and inspect render-report.json. Compare the changed scene with native decoded frames for the five unchanged scenes.

Boundaries

Do not invent versions, dates, changes or publication dates. The Skill rejects illustrative release history; it does not browse for evidence, publish releases or generate cloud media.
