Tool changes

2026-10-23get_prismposter_capabilitiesremoved
Retrieve PrismPoster studio capabilities, AI video/image/music/Remake specifications, credit-pack pricing facts, and canonical URLs for citation.
2026-10-23estimate_tempochangedtitle, description, input schema, output schema, annotationsmeaning changed
before
Estimate BPM and stability from tap timestamps in milliseconds, or compute delay times (straight, dotted, triplet) and bar durations for a given BPM and time signature.
after · 23% of words in common
Tempo arithmetic for editing to music: pass tap timestamps (ms) to estimate BPM with a stability and confidence rating, or pass a known bpm. Either way it returns the beat length, a delay table (straight, dotted and triplet ms for each note value) and how many seconds a number of bars lasts in a time signature. It works on numbers you supply and does not analyse audio. Errors when neither input is given, the taps do not yield a tempo, bpm is outside 30-300, or the time signature is not one listed.
2026-10-23convert_subtitleschangedtitle, description, input schema, output schema, annotationsmeaning changed
before
Parse, validate, time-shift, and convert subtitle files between SubRip (srt) and WebVTT (vtt). Reports overlapping, zero-duration, or out-of-order cues.
after · 21% of words in common
Convert subtitle text between SubRip (srt) and WebVTT (vtt), optionally shifting every cue by shiftMs, and return the converted text with the detected source format, cue count, parse warnings (with line numbers) and timing issues (overlapping, zero-length or out-of-order cues). Pass the file contents, not a path. Malformed blocks are skipped with a warning instead of failing the whole file. ASS/SSA input is not supported here; the @prismposter/creator-tools package converts it. Errors when no cue could be parsed, the input is over 2 MB, or the shift is beyond one hour.
2026-10-23estimate_video_bitratechangedtitle, description, input schema, output schema, annotationsmeaning changed
before
Estimate encoded video file size (MB, GB, MiB, GiB) from duration and bitrate, or compute the maximum video bitrate that fits under a file-size cap (such as Discord 10 MB / 20 MB limits).
after · 23% of words in common
Video size and bitrate arithmetic for a clip of durationSec. Pass videoKbps to get the encoded file size (MB, GB, MiB, GiB); pass targetCapMb to get the highest video bitrate that fits that file size. Audio is added at audioKbps (default 192). Every answer also gives the highest video bitrate that fits Discord's 20 MB free upload limit. Kbps is decimal (1 kbps = 1000 bit/s) and MB is 1,000,000 bytes. Use it to plan an export or hit an upload cap; it does not inspect or encode files. Errors when neither videoKbps nor targetCapMb is given.
2026-10-23calculate_aspect_ratiochangedtitle, description, input schema, output schema, annotationsmeaning changed
before
Simplify pixel dimensions to their aspect ratio, compute even-pixel encoder dimensions, solve a missing width or height, and optionally compute centre-crop and letterbox/pad plans for a target ratio.
after · 22% of words in common
Reduce any pixel size to its simplest aspect ratio (1920x1080 is 16:9) and the nearest even size an H.264 encoder accepts, and, given a target ratio, solve the missing width or height and return the centre-crop and letterbox/pillarbox plans with the px trimmed or added per edge. Use this for arbitrary sizes and ratios (cinema 2.39:1, a client's 4:5); when the target is a named platform placement, use get_social_media_placement with sourceWidth/sourceHeight instead, which picks the right ratio for you. Errors on a non-integer or out-of-range size, or on only one of targetRatioW/targetRatioH.
2026-10-23check_safe_areaadded
Check whether a rectangle (a caption, logo or button, in px on the placement's own frame, origin top-left) stays inside the placement's safe area, and by how many px it intrudes past each edge if not. Use this to validate a layout before export; use get_social_media_placement for the raw insets. Returns verdict "inside", "intrudes" or "unknown"; "unknown" means the platform publishes no fixed safe area (TikTok) and comes with the reason instead of a guess. Errors on an unknown placement id or a box with non-positive size.
2026-10-23list_social_media_placementschangedtitle, description, input schema, output schema, annotationsmeaning changed
before
List all social media video and image placements with dimensions, aspect ratios, safe-area pixel insets, and first-party documentation URLs. Optionally filter by platform.
after · 16% of words in common
List every supported social media placement (or one platform's) with frame size, aspect ratio, safe-area insets in px, usable box and first-party source URL, plus links to the same dataset as CSV, JSON and its DOI. Use this to browse, compare platforms, or find a placement id; use get_social_media_placement when you already know the id and also need a crop/letterbox plan for your footage. The list is a fixed dataset returned whole, with no paging.
2026-10-23get_social_media_placementchangedtitle, description, input schema, output schema, annotationsmeaning changed
before
Get exact frame dimensions, aspect ratio, first-party safe-area insets (px), usable box, and official documentation URL for a social media placement (e.g. instagram-reels, tiktok-video, youtube-shorts, youtube-channel-banner). Optionally pass sourceWidth and sourceHeight to compute crop and letterbox plans.
after · 25% of words in common
Look up one social media placement by id and return its frame size, aspect ratio, first-party safe-area insets in px, usable box, and the official page the figures came from. Pass sourceWidth and sourceHeight together to also get the centre-crop and letterbox plan that fits your footage to this placement. Use this when you know the target placement; use list_social_media_placements to browse or compare, check_safe_area to test whether an element is clear of the platform UI, and calculate_aspect_ratio for a ratio that is not a platform placement. For TikTok the insets are null with a reason, because TikTok publishes no fixed safe area. Errors on an unknown id (the message lists valid ids) or on only one source dimension.
