The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
audit_hook Score the opening of a YouTube script ~259
Score just the opening lines of a YouTube script: how much attention each sentence pulls, whether it opens a curiosity gap, how far away the payoff sits, plus the top issues and rewritten alternatives. Choose this when the user shares only a hook or opening paragraph, or wants a fast second opinion before auditing a whole draft. Cheaper and narrower than audit_script. This is a text-only check of an unrecorded script. It maps relative attention risk inside the draft. It does not measure or predict published YouTube retention, and it cannot account for delivery, editing, thumbnail, topic or distribution.
| Name | Type | Req | Description |
|---|---|---|---|
| string | – | Only needed once the free anonymous hook check for the day is used. Prepublish stores this address and may send a short series of follow-up emails about the check that include an unsubscribe link. As… | |
| hook_text | string | yes | The opening lines exactly as written, ideally the first 15 to 30 seconds of speech. |
| niche | string | – | Channel niche, only if the user said it. Sharpens the comparison. |
| Name | Type | Req | Description |
|---|---|---|---|
| hook | object | yes | The hook evaluation. |
| notice | string | yes | The scope limit that accompanies every Prepublish result. Repeat it to the user rather than dropping it. |
No examples provided.
audit_script Audit a YouTube script before recording ~383
Run Prepublish's full audit on a YouTube script the user has already written. Returns hook, structure and pacing scores, a script-level attention-risk map naming the passages most likely to lose viewers, and a copy-paste rewrite for each flagged passage. Choose this when the user has a finished or near-finished draft and wants to know what is weak before they record. Do not use it to generate a script, to review a published video, or to check grammar. An email is optional: the result comes back in the conversation either way. This is a text-only check of an unrecorded script. It maps relative attention risk inside the draft. It does not measure or predict published YouTube retention, and it cannot account for delivery, editing, thumbnail, topic or distribution.
| Name | Type | Req | Description |
|---|---|---|---|
| audience | string | – | Target audience, only if the user said it. |
| category | string | – | Video category, only if the user said it. |
| string | – | Optional. Only when the user gave an address and wants the result link by email: Prepublish stores it with the audit, emails the result link to it, and may send a short series of follow-up emails abo… | |
| script_text | string | yes | The script text as the user wrote it. Paste it verbatim; do not rewrite, summarise or clean it first. |
| video_duration_seconds | integer | – | Intended runtime in seconds, only if the user stated one. Used for pacing; never assumed. |
| video_title | string | yes | The title the user plans to publish under. The audit checks whether the script delivers this promise. |
| Name | Type | Req | Description |
|---|---|---|---|
| analysis | object | – | The settled audit: status (and error_message when it failed), video_title, overall_score with hook_score, structure_score and pacing_score, ready_to_record, one_key_improvement, score_explanations, t… |
| analysis_id | string | yes | Prepublish id for this audit. Pass it to get_audit to re-read the result later. |
| next_step | string | – | Present only when the audit is still running: what to do to collect it. |
| notice | string | yes | The scope limit that accompanies every Prepublish result. Repeat it to the user rather than dropping it. |
| open_in_browser | string | yes | Permalink to the same audit on prepublish.ai. |
| status | string | – | Present only when the audit had not settled inside this call; the value is "running". |
| unlock_offer | string | – | Present with unlock_url: the one sentence to relay when offering it. |
| unlock_url | string | – | Present only when part of this result is locked on the caller's plan: where the user pays to unlock it. Absent when nothing is locked. |
No examples provided.
check_authenticity Check a script for reused or inauthentic content risk ~150
Check a script against YouTube's inauthentic-content expectations: whether it reads as mass-produced, templated or repetitive, which signals fire, and what to change. Returns a score, a risk level, the firing signals with quotes, and remediation steps. Choose this when the user worries about reused content, AI-sounding scripts, or a channel that repeats a formula. This reports text-level signals only; it is not a monetisation decision and does not speak for YouTube.
| Name | Type | Req | Description |
|---|---|---|---|
| script_text | string | yes | The script text as the user wrote it. Paste it verbatim; do not rewrite, summarise or clean it first. |
| video_title | string | yes | The planned title. |
| Name | Type | Req | Description |
|---|---|---|---|
| authenticity | object | yes | The inauthentic-content read on this script. |
| notice | string | yes | The scope limit that accompanies every Prepublish result. Repeat it to the user rather than dropping it. |
No examples provided.
get_audit Collect a Prepublish audit by id ~127
Fetch the current state of an audit that was started earlier, using the analysis_id that audit_script returned. Use this when a previous audit was still running, or when the user refers back to an audit from earlier in the conversation. It performs no new analysis and costs nothing. This is a text-only check of an unrecorded script. It maps relative attention risk inside the draft. It does not measure or predict published YouTube retention, and it cannot account for delivery, editing, thumbnail, topic or distribution.
| Name | Type | Req | Description |
|---|---|---|---|
| analysis_id | string | yes | The analysis_id returned by audit_script. |
| Name | Type | Req | Description |
|---|---|---|---|
| analysis | object | – | The audit at whatever state it has reached: read its "status" field first, because an audit that has not settled carries no scores. Once settled it carries the projected report described on audit_scr… |
| analysis_id | string | yes | The id that was requested, echoed back. |
| notice | string | yes | The scope limit that accompanies every Prepublish result. Repeat it to the user rather than dropping it. |
| open_in_browser | string | yes | Permalink to the same audit on prepublish.ai. |
| unlock_offer | string | – | Present with unlock_url: the one sentence to relay when offering it. |
| unlock_url | string | – | Present only when part of this result is locked on the caller's plan: where the user pays to unlock it. Absent when nothing is locked. |
No examples provided.
policy_preflight Pre-flight a script against YouTube advertiser and monetisation policy ~174
Check a script before recording for the YouTube policy categories it may touch: which category families are implicated, the consequence family for each, a verdict and flag counts. Each category cites YouTube's own published policy page. Choose this when the user is writing about sensitive subject matter and asks whether it is safe to monetise. The quoted passages and their suggested rewrites are part of the paid audit, so the free result may return counts with locked quotes. It reports risk against published policy text; it is not a monetisation guarantee and does not speak for YouTube.
| Name | Type | Req | Description |
|---|---|---|---|
| script | string | yes | The script text as written, at least 200 characters. Below that there is not enough context for a policy read. |
| title | string | – | The planned title, if the user has one. Titles are checked too. |
| Name | Type | Req | Description |
|---|---|---|---|
| note | string | yes | Says which parts of the result are paid-only, so a locked field is not read as a clean pass. |
| notice | string | yes | The scope limit that accompanies every Prepublish result. Repeat it to the user rather than dropping it. |
| policy_preflight | object | yes | The policy read on this script. |
| unlock_offer | string | – | Present with unlock_url: the one sentence to relay when offering it. |
| unlock_url | string | – | Present only when part of this result is locked on the caller's plan: where the user pays to unlock it. Absent when nothing is locked. |
No examples provided.
script_runtime Convert script length to spoken runtime ~175
Convert a word count, or a pasted script, into a spoken runtime range, and convert a target runtime back into a word budget. Rates come from Prepublish's own measurement of 349 videos: 25th percentile 160 words per minute, median 181, 75th percentile 201. Choose this for "how long will this script run" or "how many words for a ten-minute video". It is arithmetic on speaking rate only: it excludes pauses, B-roll and demonstrations, so a finished edit usually runs longer.
| Name | Type | Req | Description |
|---|---|---|---|
| script_text | string | – | A script to count. Provide this or word_count or target_minutes. |
| target_minutes | number | – | A target runtime in minutes, to convert into a word budget. |
| word_count | integer | – | A word count, if the user already knows it. |
| Name | Type | Req | Description |
|---|---|---|---|
| caveat | string | yes | What this arithmetic excludes. Repeat it rather than presenting a single number. |
| runtime_minutes | object | – | Spoken runtime in minutes at each rate. Present when script_text or word_count was given. |
| source | string | yes | Where the rates come from, with the published write-up. |
| speaking_rates_words_per_minute | object | yes | The measured rates used, in words per minute: slow is the 25th percentile, median the 50th, fast the 75th. |
| target_minutes | number | – | The target runtime asked for, echoed back. Present when target_minutes was given. |
| word_budget | object | – | Words needed to fill the target at each rate. Present when target_minutes was given. |
| word_count | integer | – | Words counted or supplied. Present when script_text or word_count was given. |
