What is pp-mark-beats?

A command for detecting beats in audio on the first audio track of an active Adobe Premiere Pro sequence and placing markers on the timeline. It can mark every beat or only downbeats, which are the first beats of musical bars.

Use `/pp-mark-beats` to mark downbeats by default, or every beat with `/pp-mark-beats beats`, for timing edits such as reels.

It removes the need to listen through the track and place timing markers by hand, including when clips are trimmed or split.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00073	$0.00692
Opus 5	$0.00036	$0.00346
Sonnet 5	$0.00015	$0.00138
Haiku 4.5	$0.00007	$0.00069

Security

Grade A, and why

pp-mark-beats 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 10d 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 — 38 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mark beats on the timeline

Detect beats of the music on A1 and drop a marker at each one on the timeline ruler. Works on sequences of any length (a 5-min track is fine — markers are chunked).

Inputs: optional granularity — downbeats (default, one per bar — what you cut reels on) or beats (every beat, ~4x as many).

Workflow

premiere_health — plugin must be green.
get_audio_clips with audioTrackIndex: 0 (A1) — gives each clip's startSeconds, endSeconds, and mediaPath.
- No clips on A1 → tell the user and stop.
- Multiple clips on A1 → process each one (detect on its own media file, offset per clip).
detect_beats on each clip's mediaPath → beats + downbeats (in SOURCE time).
Map source beat times → timeline, using the clip's source trim points:
- get_audio_clips returns inSeconds/outSeconds (the clip's source in/out points). A clip trimmed at the head has inSeconds > 0.
- timelineTime = clip.startSeconds + (beatTime - clip.inSeconds).
- Keep only beats inside the used region: clip.inSeconds <= beatTime <= clip.outSeconds.
- If inSeconds/outSeconds come back null (a plugin build predating this field), fall back to timelineTime = clip.startSeconds + beatTime and warn that head-trimmed clips will be shifted.
add_markers, chunked at 500 markers per call (the tool's max):
- FIRST call: clearExisting: true — this is the re-run story: every sequence marker is wiped and re-added, so calling /pp-mark-beats twice never duplicates.
- Subsequent chunks: clearExisting: false.
- Marker style: name "Beat N" / "Bar N", colorIndex 7 (cyan).

Re-run semantics (what the user asked about)

There is no per-marker identity — clearExisting: true removes ALL markers on the sequence ruler, including ones the user added by hand, then this skill re-adds only beat markers. Say this in the report: "re-running replaces every sequence marker, not just beat markers." If the user has manual markers they want to keep, they should say so — then skip clearExisting and accept duplicates, or have them re-add manual markers after.
