video-timeline

video-timeline is a skill for Claude Code, Codex from Elumenotion/GuideAnts. It costs 81 tokens per session (2,045 once invoked), scanned A, original, Apache-2.0.

A spreadsheet-based story timeline for planning the visuals in a narrated video. It maps spoken story moments to images, slides, video clips, or other visual material for a person to fill in.

In plain words
What is it for?
Use it to audit narration timing, plan visual changes, assign assets, and track the status of each story moment in an XLSX file.
Why use it?
It turns a finished audio track and transcript into an editable production plan instead of requiring visual choices to be tracked informally.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

video-timeline scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/build_timeline.py, scripts/qa_timeline.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

video-timeline

Third step of the video-production pipeline (after session-ingestion-scripting and TTS generation). Paths — fixed layout, do not probe. The sandbox CWD is the notebook's output directory; write every deliverable to the CWD with a bare filename (never prefix Output/). Scripts live under Skills/<skill>/scripts/ relative to the CWD — run the commands in this file exactly as written.

Requires openpyxl (for the .xlsx deliverable); everything else is stdlib. pip install openpyxl if missing.

What this skill produces — and what it deliberately is not

The deliverable is a story document a human edits: one xlsx, one row per story moment, with dropdowns for visual type (New Image / Slide / Video Clip / Session B-roll / End Card / Hold), an empty Asset/file column the user fills, and a Status workflow (To-do → Have → Verify → Done).

It is not a frame map. Extracting frames, aligning raw-footage spans, and building storyboards are optional internal means to inform suggestions — never the deliverable. The user's standing instruction: help me build the visual timeline to tell a story, not to map the video frames.

Learnings that are binding for this skill (from the 2026-08-27 intro-video session — do not regress):

  1. Audit the audio first. The picture plan is driven by measured numbers (WPM per 30-s bucket, the real pause ladder, 0-s/1-s TTS seams, missing tail), not by taste.
  2. Rows are story moments, chained with no gaps from 0:00 to audio-end + a 1.5–2.5 s tail pad. Split or merge freely; keep the chain unbroken.
  3. "What Doug says" is a plain-English summary of the narration at that time — never a verbatim transcript dump, never longer than ~60 words.
  4. The assistant proposes, the user decides. Pre-fill Visual type + What to show as suggestions; the user owns the asset choices.
  5. QA is scripted, not vibes. qa_timeline.py produces a 100-point score with per-check evidence; quote it, do not assert.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
