Edit a talk-to-camera or demo screencast recorded in Camtasia for Mac (screen, camera and mic in one take) into a speaker-first video: plan cuts on sentence boundaries from Camtasia's own word timings, frame and zoom the screen evidence, audit the framing against the recorded pointer, generate the Camtasia project, correct the dynamic captions, time the YouTube chapters, and compose the thumbnail from frames of the take. Use when the user has a new Camtasia recording to edit, wants captions…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

Process steps in order. Do not skip ahead.
Resolve the absolute path of this loaded `SKILL.md`, then set
`speaker_toolkit_root` to the plugin root two directories above the directory

Camtasia owns any project it has open. Never write a project file until the
user has saved and closed it. Never screenshot the whole screen. Look at pixels
only through the stills this skill renders.
Every script prints its diagnostics on stderr and exits 2 on a usage error
(bad or missing arguments); each step lists its other outcomes.
Steps 2, 8, 9, 10, 13, 14, 15, 16, and 17 hand work to the user and end the turn. When the user

How to install
mdr add jbaruch/speaker-toolkit/screencast-editor@sha256:ff1eb8a17e2eb4ffThe line at the top of this page pins the label git:20260929.9beca99, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
