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 | $0.00199 | $0.02162 |
| Opus 5 | $0.00100 | $0.01081 |
| Sonnet 5 | $0.00040 | $0.00432 |
| Haiku 4.5 | $0.00020 | $0.00216 |
Grade C, and why
screens 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 6d 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.
degradation, never refuse the stage over tooling. How it starts
The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: screens
Turns the approved architecture into the screen manifest — the one artifact tasks,
implement and review read for what every screen shows in every state. It runs between api
and tasks: by then the states are derivable, not invented — default plus every state the
spec §5 ACs, the sad.md §6 alt/else branches, and the contract error responses imply
(loading / empty / error / success / validation). Per state it names the components to reuse
from the docs/design-system.md inventory — a NEW: component only with a
why-no-primitive-fits justification. The visuals are drawn per the canon's tool; whatever the
tool, the manifest is the contract — downstream never reads the raw Figma/.pen file.
Optional by surface: its N/A condition (no UI surface in sad.md target_surfaces) lives in
../_shared/size-matrix.md and is evaluated by api's handoff
(carried forward when api itself is N/A). Invoked directly, it always runs.
Question phrasing → ../_shared/ask-style.md. Manifest prose follows
artifact_language — state tokens (default/loading/…), SCR ids, component names and
source-refs stay English → ../_shared/artifact-language.md.
Owner
Designer + frontend lead. The PM confirms the states match the ACs; review later checks the
built screens against this manifest.

What ships with it
1 file 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.

screens is a skill published in the GitHub repository genkovich/sdd (119 stars, last pushed today), licensed MIT. It adds 199 tokens to every session and 2,162 once invoked, about $0.0010 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.
