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 | $0.00028 | $0.01441 |
| Opus 5 | $0.00014 | $0.00720 |
| Sonnet 5 | $0.00006 | $0.00288 |
| Haiku 4.5 | $0.00003 | $0.00144 |
Grade A, and why
preflight 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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

preflight is a skill published in the GitHub repository webiny/webiny-js (8,031 stars, last pushed today), with no licence file. It adds 28 tokens to every session and 1,441 once invoked, about $0.0001 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.

migrate-internal-package
Move a package from another TryGhost repository into Ghost as an internal-only workspace package while preserving its Git history. Use for package migrations from repositories such as TryGhost/SDK or TryGhost/framework, including the history import PR, exceptional merge-commit handoff, source-repository removal PR…
Shade tokens, not hex
Use Shade semantic tokens (bg-background, text-foreground, border-border-default, bg-surface-elevated) — never hex, hsl(), or bg-gray-200-style raw palette utilities for UI chrome. Trigger when editing TSX/CSS in Shade-consuming apps.
Shade dropdown surface contract
DropdownMenu, Select, and Popover share one visual recipe (bg-surface-elevated-2 + border-border/60 dark:border-border/30 + shadow-md). Change them together. Trigger when editing any of those three Shade files.
Shade inputSurface recipe
Use the inputSurface() recipe for form-control chrome (border, background, radius, focus ring, invalid state) — don't roll your own. Trigger when editing form-control-shaped files in Shade.
Shade new component
Acceptance checklist for adding or editing a Shade component or pattern file — naming, sibling story, className forwarding, cva variants, required states, recipe usage. Trigger when editing files in apps/shade/src/components.
Shade page templates
Pick the right Shade page template (ListPage, PageHeader) for a new admin page instead of inventing chrome. Trigger when creating new admin pages or routes in apps/admin or apps/activitypub.
