timecode-agent

A workflow for understanding and indexing existing videos using timestamps, transcripts, visual checks, and reusable notes.

In plain words
What is it for?
Use it to ingest videos, search a video collection, verify uncertain moments, create highlights, and prepare editing handoffs.
Why use it?
It helps locate specific scenes, speakers, quotes, or events without reviewing every video frame by frame.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

timecode-agent 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 2d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 285 lines — stays where its author put it; the contents beside it link to each section on GitHub.

TIMECODE-AGENT

Hypothesize from the transcript first, verify only the uncertain moments visually, then persist the result as checkpoints. Never capture every frame; state the hypothesis each capture tests. Never promote a device- or dataset-local number into a universal rule.

Request to loop routing

Fold the user's words into a loop first. Step numbers come after.

User says Loop Entry
new video, understand, analyze, "what is this" Ingest (develop) then Kubrick (understand) step 0: va ingest --signals, then va brief
highlight, shorts, "cut this" Kubrick, then the cut workflow of Kuleshov (edit) named span self-converges (step 4); open-ended waits for global convergence
"where was that scene", recall Search va searchnever re-ingest
Premiere, editor handoff, markers Bridge va export in step 5
listing, wiki, browser, external vault refresh Archive (project knowledge) va index, va wiki, va view, va bridge

Pipeline: ingest (develop), search (recall), Kubrick (understand), Kuleshov (edit), cut (assemble), archive (preserve).

Kubrick writes the fact ledger (checkpoints.jsonl); Kuleshov writes the edit decision ledger (sequences.jsonl). Kuleshov never modifies the fact ledger. Correct a factual error in the checkpoint, then derive the edit again.

Files

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

timecode-agent is a skill published in the GitHub repository mupozg823/timecode-agent (53 stars, last pushed 26d ago), licensed MIT. It adds 113 tokens to every session and 3,469 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
