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 | $0.00110 | $0.01238 |
| Opus 5 | $0.00055 | $0.00619 |
| Sonnet 5 | $0.00022 | $0.00248 |
| Haiku 4.5 | $0.00011 | $0.00124 |
Grade A, and why
x-post 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 9d 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 — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.
x-post: X / Twitter post image
Goal: produce the PNG asset of a tweet image, at the chosen ratio, aligned with the guidelines.
This is a specialization of new-template with the X constraints hard-coded. Same
conventions: the Template contract, assets through brand(), fonts discovered
in fonts/, export default ... satisfies Template.
Status of the dimensions. X documents no dimensions for organic tweet images; only the weight (5 MB) is official. The sizes below are conventions aligned with the ratios X lists for its advertising formats.
0. Prerequisites (blocking)
The chain project -> template folder -> guidelines must exist:
- Resolve
<project>(from the arguments, otherwise ask). - Check
templates/<project>/andbrands/<project>/brand.md. - Missing guidelines or project -> STOP: ask for
/new-project <project>first. No visual without guidelines (CLAUDE.md rule).
1. Frame it
- Which orientation? Ask. Default: 16:9 landscape (the classic format of the X feed). Otherwise square (1:1) or portrait (4:5).
- Default slug
x-post(orx-post-<orientation>if there are several). Check that the target.tsxdoes not exist. - Read
brands/<project>/brand.md: palette, type, logo variants, don'ts. - Read
brands/<project>/project.mdif it exists: set the tone and the claims (don't invent figures or promises). If absent -> ask for the tone and the message rather than guessing. - Ask for the message: short headline + standfirst (1 sentence). No paragraph.
2. X constraints (to respect)
| Orientation | Size (px) | Ratio | Status |
|---|---|---|---|
| Landscape (default) | 1600x900 | 16:9 | Convention (X ads ratio) |
| Square | 1080x1080 | 1:1 | Convention (X ads ratio) |
| Portrait | 1080x1350 | 4:5 | Convention (X ads ratio) |
- Format: PNG or JPG, opaque background, ≤ 5 MB (the official limit for tweet images; trivial with flat rendering).
- The tweet's text lives outside the image, in the post: don't write everything into the visual. One idea per image.
- Legible when small: the X feed scrolls fast and narrow on mobile. Large headline, short standfirst, strong contrast, safe area of about 80 px.
- X tone: direct, punchy, concise. The feed rewards a sharp line.
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.

x-post is a skill published in the GitHub repository roslove44/brand-artisan (4 stars, last pushed 12d ago), licensed MIT. It adds 110 tokens to every session and 1,238 once invoked, about $0.0006 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 2026-08-31.
