frame-smith: Instructions file for Codex

AGENTS.md

frame-smith AGENTS.md is an instructions file for Codex, OpenCode from mouse-lin/frame-smith. It costs 2,962 tokens per session, scanned A, original, MIT.

Agent instructions for frame-smith, a tool that turns a brief into registered Remotion video compositions but does not render them.

In plain words
What is it for?
They guide cinematic landscape clips and short vertical clips, including resolution, frame rate, duration, subtitles, voiceover, safe zones, and motion standards.
Why use it?
They make the agent check for a Remotion runtime and follow the project’s required production workflow before writing code.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md; mentions Codex.

This is mouse-lin/frame-smith's own configuration. It tells Codex and OpenCode how to work on frame-smith itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything frame-smith configures →

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

frame-smith AGENTS.md 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 1mo 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.

frame-smith — Agent Instructions

For OpenAI Codex and other agent runtimes that read AGENTS.md. The full skill is at skills/frame-smith/SKILL.md. Deep reference material lives in skills/frame-smith/references/. Load what you need per phase — do not inline everything at once.


What frame-smith does

frame-smith is a director, not a renderer. It reads a brief, decides what the video is, writes a Remotion composition (.tsx), and registers it — but it does not own the runtime. It builds two registers:

  • cinematic — a landscape clip, 1920×1080 · 30fps, ~12–24s, pure visual, no voiceover (music + SFX still apply), ending on a wordmark/logo payoff.
  • short — a vertical clip, 1080×1920, for 抖音/小红书/视频号, may carry subtitles + voiceover, hook by ~1.5s. Obeys the S = width/720 scale system and 抖音 safe zones.

The through-line both share: high motion craft, zero motion-slop — the motion craft floor and the anti-slop blacklist.


0. ENVIRONMENT GATE — hard requirement, run FIRST

frame-smith cannot render on its own. At least one of the hyperframe or remotion skills (or a Remotion project on disk) must be present — see skills/frame-smith/references/environment.md, or run bash skills/frame-smith/scripts/check-runtime.sh.

  • Neither present → STOP. Write no .tsx. Report it and offer install (hyperframe preferred — carries the effect templates; remotion = leaner runtime). Ask for a path before assuming any; never hardcode one.
  • One present → record which (it decides where the composition lands + how to register/preview), then proceed.

Commands (targeted iteration)

A full build runs the whole workflow below. For iterating on an existing composition, route the request through one verb instead of rebuilding — Codex has no slash commands, so map the user's intent to the verb and load only that reference. The env gate (§0) still runs first for any verb that writes or renders.

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.
