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 | $0.00062 | $0.00920 |
| Opus 5.5 | $0.00025 | $0.00368 |
| Sonnet 5.5 | $0.00012 | $0.00184 |
| Haiku 4.5 | $0.00006 | $0.00092 |
Grade A, and why
blog-promo-kit 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 3d 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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Blog and article promo kits
One URL, one generation, the whole distribution set. Canvora extracts the article itself, so every asset carries the same argument and the same look, which is exactly what hand-assembling these one at a time fails to do.
The generate loop and credits: see the canvora skill.
The two jobs, don't confuse them
On-page assets (the post needs these to ship):
| Format | Size | Role |
|---|---|---|
blog_header |
16:9 1200×675 | the in-post header image |
blog_featured |
16:9 1920×1080 | featured/hero image in the CMS |
og_image |
16:9 1200×630 | the social share card: the one everyone forgets |
web_banner |
21:9 1920×550 | category/section banner |
Off-page distribution (the post needs these to travel):
linkedin_post, instagram_carousel_portrait, twitter_post, quote_card,
stat_card.
og_image is the highest-leverage asset here: it is what appears in every
share, every Slack paste, every LinkedIn link preview. If the user asked only
for "a blog image", ask whether they have an OG card; usually they don't.
Intake
- The published URL (public and live: extraction fetches it).
- Do they need on-page, distribution, or both? Default: both.
- Which channels do they actually post to? Don't generate a TikTok asset for someone who only uses LinkedIn.
- Brand kit →
brand_id(+embed_logofor the social assets; headers usually read better without).
The canonical runs
chat messages:
From [the article URL], create blog_header, og_image, linkedin_post and a 6-slide instagram_carousel_portrait, using our brand kit.
From [the article URL], create blog_featured and og_image.
From [the article URL], create linkedin_post, twitter_post and a quote_card.
Then confirm_generation with brand_id and poll get_generation.
Cost check: the first example is 3 singles (30) + a 6-slide carousel (90) = 120 credits. Say it in the same message as the run: announce it, don't ask permission. If the slide count was your call rather than the article's, confirm that number.
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.

blog-promo-kit is a skill published in the GitHub repository canvora/canvora-mcp (1 stars, last pushed 4d ago), licensed MIT. It adds 62 tokens to every session and 920 once invoked, about $0.0002 per session on Opus 5.5. 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.
