Measured tools (10)

• search_videos

  Full-text search over BuildFeed's curated AI/startup/VC YouTube video library. Scores videos by keyword match across title, topics, TLDR summary, channel name, and key takeaways, ranked by relevance (then recency). Use this when the user asks about a specific topic, person, product, or company and you need to find relevant videos with summaries — not when you just want to browse everything (use list_videos for that instead).

  Parameters:

  • query (required) — string — Search keywords, e.g. "Claude agents", "seed fundraising", "Figma design systems".
  • limit — integer — Max results to return (default 20, hard cap 50).
  • since — string — Only videos published on or after this ISO 8601 date (reads the archive index).
  • category — string — Restrict results to one category: AI, VC, Startup, Product, Design, or Tools.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• search_transcript_passages

  Search inside transcript passages, returning the most relevant timestamped excerpts across multiple videos. Use this for evidence, quotations, implementation details, or questions whose answer may not appear in a title or summary.

  Parameters:

  • query (required) — string
  • limit — integer
  • topic — string
  • audience — string
  • category — string
  • contentType — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_transcript

  Get a bounded transcript window for one video. Prefer search_transcript_passages for discovery; use this tool to inspect surrounding context after selecting a video.

  Parameters:

  • videoId (required) — string
  • maxChars — integer
  • endSeconds — number
  • startSeconds — number

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_videos

  List curated BuildFeed videos, optionally filtered by category and sorted by recency, views, likes, or quality score. Returns compact video records (title, channel, categories, view/like counts, quality score) without transcript or description text. Use this to browse recent/top videos; use search_videos instead when looking for a specific topic.

  Parameters:

  • sort — string — Sort order: recent (default), views, likes, or quality.
  • limit — integer — Max videos to return (default 20, hard cap 50).
  • since — string — Only videos published on or after this ISO 8601 date. Searches the full archive; videos outside the rolling cache have qualityScore 0 and commentCount 0.
  • category — string — Restrict to one category: AI, VC, Startup, Product, Design, or Tools.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_video

  Get full detail for a single BuildFeed video — description, channel info, stats, categories, topics, TLDR, and key takeaways (the raw transcript text itself is excluded). Accepts either an 11-character YouTube video ID or a BuildFeed article slug. Use this after search_videos/list_videos to drill into one specific result.

  Parameters:

  • id (required) — string — YouTube video ID (11 chars, e.g. "dQw4w9WgXcQ") or a BuildFeed article slug.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_channels

  List YouTube channels tracked by BuildFeed, with per-channel video counts and categories, sorted by video count descending. Use this to discover which creators BuildFeed covers, optionally filtered to a category.

  Parameters:

  • limit — integer — Max channels to return (default 20, hard cap 50).
  • category — string — Restrict to channels that have published in this category.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_categories

  List all of BuildFeed's video categories (AI, VC, Startup, Product, Design, Tools) with the number of videos in each. Use this to understand the taxonomy before filtering search_videos/list_videos/list_channels by category.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_topics

  List canonical topic clusters from the full BuildFeed archive, grouped into stable families such as AI & Models, Building, Product, Startups, and Industry. Returns video counts, aliases, content-type distribution, and audience labels.

  Parameters:

  • group — string — Optional exact topic family, e.g. "Building" or "Startups".
  • limit — integer
  • minVideos — integer — Only return clusters with at least this many videos.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_stats

  Get aggregate statistics for the entire BuildFeed corpus: total videos, channels, categories, topics, and views; the published-date range; and transcript/TLDR enrichment coverage. Use this for high-level "how much data / how fresh" questions rather than per-video detail.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_weekly_roundup

  Get BuildFeed's weekly roundup content. Without a date, returns the index of available weekly roundups (most recent first) — useful for discovering which weeks exist. With a date (YYYY-MM-DD week key), returns that week's full roundup detail. Use this for "what happened this week" or historical week-by-week summary questions.

  Parameters:

  • date — string — ISO date (YYYY-MM-DD) identifying a specific week. Omit to list available weeks.
  • limit — integer — When listing weeks (no "date" given), max entries to return (default 20, hard cap 50).
