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.

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 | $0.00113 | $0.02886 |
| Opus 5 | $0.00056 | $0.01443 |
| Sonnet 5 | $0.00023 | $0.00577 |
| Haiku 4.5 | $0.00011 | $0.00289 |
Grade C, and why
shader-gen scanned grade C with 1 finding 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 12d 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.
Tells the agent never to refusehighAnti-refusal
Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.
- Generation always produces a library asset — never refuse because the timeline isn't ready. How it starts
The opening of the file, as written. The whole thing — 219 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Shader Generator
Submit-only: creates a backend generation job, returns jobId. Use the track_progress tool for job lifecycle after submission.
Always use generate.ts for new shaders. Manual authoring is only for editing existing asset code — never as a fallback when generation fails.
Catalog-first rule — try existing assets before generation
Before generating a shader, call browse_library unless the user names an exact asset id that is already visible in read_project.
browse_library is the source of truth for built-in effects, built-in transitions, and project effect/transition assets. Built-ins are stable global asset ids, not per-project DB assets, so they may not appear in read_project asset lists.
Apply catalog entries with edit_item, do not call submit_shader.
Good catalog searches:
browse_library(query: "zoom")
browse_library(category: "transitions", query: "dissolve")
browse_library(category: "audio-fx")
Generate only when no catalog entry matches the user's intent closely enough.
builtin:zoom is track-bound only — DO NOT use item-bound
The default effect mode is "item-bound" (attach to a single item via targetItemId). builtin:zoom does NOT render in item-bound mode — the renderer reads zoom data exclusively from track-bound effect items. An item-bound zoom inserts into the DB silently but shows nothing in preview.
Use mode: "track-bound" with trackId + trackBoundFrom + trackBoundDurationInFrames. These three fields are required.
# Zoom on the entire video clip
edit_item(json: '{"adds":[{"type":"effect","assetId":"builtin:zoom","mode":"track-bound","trackId":"<clip-trackId>","trackBoundFrom":<clip-fromFrame>,"trackBoundDurationInFrames":<clip-durationInFrames>,"propertyOverrides":{"magnification":1.5,"shape":"hold"}}]}')
# Zoom on a sub-range of the clip (e.g. frames 90–150 only, a punch zoom on a beat)
edit_item(json: '{"adds":[{"type":"effect","assetId":"builtin:zoom","mode":"track-bound","trackId":"<trackId>","trackBoundFrom":90,"trackBoundDurationInFrames":60,"propertyOverrides":{"magnification":2,"shape":"punch"}}]}')
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.

shader-gen is a skill published in the GitHub repository gabrielmoreira/agent-skills-mirror (17 stars, last pushed yesterday), licensed MIT. It adds 113 tokens to every session and 2,886 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it C with 1 finding (tells the agent never to refuse). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
