What it does

API Scripts is an agent skill from nodetool-ai/nodetool. Call nodetool.scripts from a code action: create a voice script, add speakers with voices and spoken lines, voice the lines as audio takes, and assemble the takes into a voiceover timeline with word timings. Load before the first call into nodetool.scripts.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative, covering Text to speech and voice. The repository describes itself as: Agent-first Creative Workspace. The licence is AGPL-3.0.

When your agent uses it

  • Tasks that involve Text to speech and voice

Example prompts

  • “/api-scripts”

What it can do on your machine

Read from SKILL.md and the folder at commit 515bd28. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

API Scripts loads about 1k tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 458 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Call nodetool.scripts from a code action: create a voice script, add speakers with voices and spoken lines, voice the lines as audio takes, and assemble the takes into a voiceover timeline with word timings. Load before the first call into nodetool.scripts.

nodetool.scripts

A script (a voice script) is a cast of speakers, each with a voice, and the lines they speak in reading order. Voicing a line makes an audio take. Assembling lays the takes into a timeline. A JavaScript script is a different document (nodetool-js-scripting). A video timed to a written voiceover is script-video.

CallDoesAnswers
list({limit})Lists scripts, newest first, with cast size, line count, voiced count and the timeline it was assembled into.Script rows
create(name, {project_id, id})Creates an empty script. An existing id is returned as it is, so a retry makes no copy.{script_id, …}
get(id)Reads the cast and every line with its id, index, speaker, text, direction, pause, effective voice and voicing status.The script
edit(id, ops)Applies ops in order and saves. An open editor picks the change up live.The result of each op
voice(id, opts)Calls the TTS provider for the lines.The takes it made
assembleTimeline(id, {name, fps})Lays the voiced takes end to end into a timeline.The timeline id, and the lines it skipped

Line status is draft (never voiced), stale (the text or voice changed since the take), voiced or no_voice (the speaker has no voice).

Ops

A line target is its id, its 0-based index in the whole script, or its exact text. A speaker target is its id or name. An argument an op does not take is refused.

OpArguments
set_setupstage?, brief?, format?, length_seconds?, pace?, language?
add_speakername, color?, provider?, model?, voice?, entityId?
set_speakertarget, name?, color?, entityId? — renames or recolours a speaker
set_speaker_voicetarget, provider, model, voice, settings?
remove_speakertarget
add_sectiontitle?
add_linetext, speaker?, section?, direction?, pause_after_ms?, index?
set_line_texttarget, text
set_line_speakertarget, speaker — the op that gives a line its speaker
remove_linetarget
  • format is voiceover, dialogue, interview, ad-read or tutorial.
  • entityId makes the speaker a cast character from the entity library, so storyboard renders can use it.
  • A rewritten line keeps its takes as stale, so the next voice() records exactly those again.
Show full SKILL.md (123 more words)Show less

voice

  • Omit targets to voice every line that is unvoiced or stale. A whole script is one call.
  • targets takes line ids, indexes or exact texts.
  • Each line uses its own voice, else its speaker's. provider, model and voice together override every line. Pick the model with nodetool.models.pick("text_to_speech").
  • speed, concurrency (default 3, max 8).
  • Word timings are transcribed for captions (transcribe, default true; asr_provider and asr_model default to openai and whisper-1).
  • Earlier takes are kept, and the new take becomes current.
js
const { script_id: id } = await nodetool.scripts.create("Launch VO");
await nodetool.scripts.edit(id, [
  { op: "add_speaker", name: "Narrator" },
  { op: "set_speaker_voice", target: "Narrator", provider, model, voice },
  { op: "add_line", text: "Meet the lamp that listens.", speaker: "Narrator" }
]);
await nodetool.scripts.voice(id);
const cut = await nodetool.scripts.assembleTimeline(id);

Each assembled clip carries its word timings, the speaker label and a link to its line, so a re-voiced line can round-trip into the cut. Running the assembly again rebuilds the same timeline in place. Validate it with nodetool.timelines.validate before a render.
