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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.01111 |
| Opus 5 | $0.00018 | $0.00556 |
| Sonnet 5 | $0.00007 | $0.00222 |
| Haiku 4.5 | $0.00004 | $0.00111 |
Grade A, and why
broll-remotion-build 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 10d 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Remotion Lead / Chapter Builder
Remotion is explicit opt-in or canary in v1.0.1, not the production default.
Own only the assignment-selected role and source tree. Never change SRT timing,
Recipe truth, another chapter, runtime selection, or Parent-generated media
contracts. A failure never silently switches backend.
Complete creative context
Read the complete original SRT and original design directly; a summary cannot replace either. Use the assignment-selected role prompt, this assignment, its Recipes, chapter/seam context, shared asset/font index, Lead samples and capability index, exact project-local Remotion toolchain, and at most two selected references. Do not reopen Parent/other stage Skills, schemas, validators, generic craft references, backend guides, full catalogs, or command source.
truth is immutable. creativeProposal is revisable: change its metaphor,
objects, composition, motion, material route, or key states when a better
answer preserves the audience outcome and required readable result. Record one
concise reason, not a new approval workflow.
Do not create src/inspection.tsx, inspection Compositions, DOM trace markers,
motion windows, dense diagnostics, capture/trace/lint/screenshot/frame-scan/
hash/probe/decode/manifest/contract/receipt/proof tools, or passing proof
artifacts. Parent owns deterministic rendering and media evidence.
Use only the assignment's exact local packages, CLI, profile, and prepared
dependency identity. Never use global packages, download-style npx, a private
per-unit install, HyperFrames execution, or a substituted profile. All visible
motion derives from current frame/fps, deterministic math, or fixed seeds; no
CSS time animation, timers, ambient state, network-at-render, wall clock, or
unseeded randomness.
Use project-local font loading for every visible typeface named by the
assignment; generic or host-system fallback is forbidden. Parent owns
dependency preparation, typecheck, bundle reuse, direct shot rendering, and
the fixed two-slot heavy-work queue. Parent ensures one dependency identity
installs once per production root through remotion-toolchain.mjs prepare.
Do not run a private per-unit dependency install. Parent invokes heavy commands through
remotion-toolchain.mjs run-heavy.
What ships with it
5 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.
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.

broll-remotion-build is a skill published in the GitHub repository erduo1998-cell/erduo-broll-loop-engineering (170 stars, last pushed 3d ago), licensed MIT. It adds 37 tokens to every session and 1,111 once invoked, about $0.0002 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.
