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 | $0.00432 | $0.08385 |
| Opus 5 | $0.00216 | $0.04193 |
| Sonnet 5 | $0.00086 | $0.01677 |
| Haiku 4.5 | $0.00043 | $0.00839 |
Grade B, and why
generate-consistent-og-images scanned grade B with 2 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 11d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
No MCP server is required. Ideogram's v3 endpoint accepts a direct HTTPS request with `Api-Key` header. Bash + `curl` is enough. If a future MCP wrapper is preferred, register it the same way the firecrawl/tavily wrapper How it starts
The opening of the file, as written. The whole thing — 382 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Generate Consistent OG Images
Two techniques, either one valid: generate a wordless illustration with Ideogram (two variables per request — aspect ratio and a one-sentence prompt; everything else locked at the
DESIGN.mdlevel), or rasterize the project's own hero/specimen component withqlmanage+sips. Illustration quality is stochastic — some runs land, some don't — while a hero rasterization is deterministic and on-message whenever the hero already says the thing. Pick per project, or per format, and let both coexist.
When to use this skill
- A site, splash page, plugin page, or fundraise deck needs an OG image generated for the first time
- An existing OG image needs to be refreshed (rebrand, stale visual, new feature launch)
- A new format is needed alongside an existing one (e.g. you have
bannerbut now needbanner_tallfor WhatsApp / iMessage) - The user asks for "an image for this page" or "an image for this component" that may or may not follow the OG canon
- Scaffolding a new Astro Knots site that doesn't yet have a
DESIGN.mdat all - "The link unfurl looks wrong" — the OG image is missing, off-brand, or in the wrong format
Philosophy (Lossless OG preference)
The Lossless Group optimizes share imagery for mobile chat previews — iMessage and WhatsApp first — and treats LinkedIn / Twitter / Bluesky / Slack as concentric rings around that target.
In practice this means:
- Tall aspect ratios get production attention, not just landscape banners.
3x4(WhatsApp / iMessage default) and2x3(extra-tall) variants are first-class assets, not afterthoughts. - Subject lives in the lower portion of the frame by default so the top half stays clean for the receiver's preview crop (chat platforms aggressively top-crop tall images).
- The 1200×630 OG-canonical banner is one format among several, not the only target. Other social-specific banners (LinkedIn portrait, Twitter Card) are still produced when needed, but never at the expense of a polished tall variant.
What ships with it
2 files 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.

generate-consistent-og-images is a skill published in the GitHub repository lossless-group/lossless-agent-skills (4 stars, last pushed 18d ago), licensed MIT. It adds 432 tokens to every session and 8,385 once invoked, about $0.0022 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
