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 | $0.00054 | $0.00826 |
| Opus 5 | $0.00027 | $0.00413 |
| Sonnet 5 | $0.00011 | $0.00165 |
| Haiku 4.5 | $0.00005 | $0.00083 |
Grade A, and why
Shade use primitives 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Shade — use primitives, not flex divs
A <div> whose className is only flex / grid / gap / items-* / justify-* utilities is a primitive call site. Use a Shade primitive instead so layouts read by intent, not by class string.
import {Stack, Inline, Box, Grid, Container, Text} from '@tryghost/shade/primitives';
Picking the primitive
| You need | Use | Element |
|---|---|---|
| Column of children | Stack |
flex-col |
| Row of children | Inline |
flex-row (with optional wrap, as) |
| Padding / radius around content | Box |
div with padding, radius props |
| Two-dimensional layout | Grid |
display: grid |
| Width-constrained shell | Container |
max-width wrapper |
| Text with size/tone/weight | Text |
as, size, tone, weight |
Use the semantic gap scale, not raw numbers
gap="md" reads as intent and resolves to the shared spacing scale. Mapping:
| Step | Tailwind | Use for |
|---|---|---|
none |
gap-0 |
flush |
xs |
gap-1 |
inline icons-to-text |
sm |
gap-2 |
dense lists, badges |
md |
gap-3 |
default row/column spacing |
lg |
gap-5 |
section spacing |
xl |
gap-6 |
between major blocks |
2xl |
gap-8 |
page-level rhythm |
The same scale applies to Box padding (padding="md" → p-3).
Correct
<Box padding="lg" radius="md" className="border border-border-default">
<Inline align="center" gap="md" justify="between">
<Stack gap="xs">
<Text weight="semibold">Email notifications</Text>
<Text size="sm" tone="secondary">Get notified about engagement.</Text>
</Stack>
<Switch />
</Inline>
</Box>
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.

Shade use primitives is a skill published in the GitHub repository TryGhost/Ghost (55,095 stars, last pushed today), licensed MIT. It adds 54 tokens to every session and 826 once invoked, about $0.0003 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.
