Hook Layer

Analyze a TikTok, YouTube, or Instagram creator by handle or channel ID. Returns viral DNA scores (viral_dna_score, replicability_score, originality_score, consistency_score, audience_fatigue), content patterns, format fingerprint, top recent videos with transcripts, content gaps, a headline_insight object (the single largest quantified performance gap across length, hook, format, and cadence, plus its so_what), and suggested next research steps. Use when the user asks to analyze a creator, account, channel, or competitor. Supports TikTok (full transcript extraction), YouTube (Shorts and longform analysis with captions when available), and Instagram (Reels with best-effort transcripts).

analyze_account

Turn a brand brief that just landed into a one-page creative blueprint the manager can forward to the creator and to the brand contact — hook + template + hashtag combo + trend-velocity check + shoot instructions, in one call. Use when a brand sends a product and needs content on a tight turnaround (e.g. "product arrived, need content in 48 hours") and the manager needs a defensible direction with no research time. Chains find_viral_template + trend_pulse + score_hook + predict_virality upstream but exposes them as one MCP tool so agents don't stitch them manually. Cost 7 credits (bundle discount vs firing the chain manually). Returns a blueprint object with verdict (GO | NEEDS_MORE_DATA | NO_GO) and verdict_reason, a hook (text + trend_still_alive: up-slope | plateau | fading | unknown), script, hashtags, shoot notes, risk flags, and manager talking points, plus a quality object (level + reason) describing completeness; when quality.level is not "full", or verdict is NEEDS_MORE_DATA or NO_GO, the blueprint is a starting point rather than a shippable direction.

brief_to_blueprint

Detect what changed since the last saved baseline for a tracked creator. Runs a fresh analyze_account under the hood, compares against the most recent CreatorSnapshot, persists the new snapshot, and returns ONLY the meaningful shifts (format, viral DNA, engagement, hook pattern, topic pillars, outlier videos). Use when the user asks 'what changed with @creator', 'anything new', 'check this competitor again', 'what's different since last time', 'check my tracked creator', or 'has anything changed'. Requires a previously tracked creator (call analyze_account + watch_account first if there is no baseline yet). Costs 5 credits per call because the fresh analysis is genuine (not cached). Returns a top_action pointing at the single next tool worth calling given the detected change. Returns status='no_meaningful_change' honestly when nothing shifted — no fabricated deltas.

get_changes

Find proven viral templates in a niche with example videos. Returns templates ranked by performance, including hook patterns, format structures, average views, and example URLs. Use when the user asks what's working in a niche or wants concrete copyable structures. Supports 17 niches with optional angle narrowing via query parameter for more specific results (e.g., "postpartum strength" within Fitness).

find_viral_template

Research what is currently gaining traction in short-form content for a specific niche. Returns rising opportunities (formats, hooks, styles, topics) with growth signals, data sources, and saturated patterns to avoid. Use when the user asks what to post about, what's trending in a niche, or needs to validate a content idea against current trends. Supports 17 niches and optional region filtering.

trend_pulse

List every creator the authenticated user is tracking. Read-only, 0 credits. Returns each watch's id, platform, handle, when it was created + last updated, when the last snapshot was taken, and whether it's active. Does NOT return the snapshot payload itself — call watch_account (idempotent) to refresh a baseline. Use when the user asks 'what am I tracking', 'show my watches', 'list creators'.

list_watches

Extract a creator's voice DNA from reference samples and rewrite a draft in their style. Requires at least 3 reference samples (video URLs or text). Returns voice profile (energy, humor, vocabulary, signature phrases), reusable prompt instructions, and the rewritten draft. Use when the user wants to write in another creator's style or match a specific voice.

match_voice

Score a draft script for viral potential with adversarial verification. Returns a virality score, recommendation (ship/rework/no-go), viral DNA breakdown with evidence, attack vectors analysis, and calibration metrics. Use when the user has a finished draft and wants pre-publish verification. Pass either a script string or a video URL.

predict_virality

Take a viral video and produce a fresh script that mirrors its structure and energy pattern for a new topic. Returns the extracted formula, scene-by-scene script with voiceover and visuals, camera directions, and text overlays. Use when the user finds a video they want to replicate the structure of. Pass either a video URL (TikTok, YouTube, or Instagram) or a transcript directly. When promoting a specific product, ALWAYS pass target_product + verified_product_facts so the generator does not fabricate product details.

viral_remix

Score a TikTok, Reels, or Shorts hook against proven viral patterns. Returns a 0-100 score, percentile rank, matched pattern, strengths, weaknesses, and three improved hook variations. Use when the user has a draft hook to validate, wants to compare alternatives, or needs feedback before publishing.
