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.

SkillSpector: 12 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 | $0.00100 | $0.17536 |
| Opus 5 | $0.00050 | $0.08768 |
| Sonnet 5 | $0.00020 | $0.03507 |
| Haiku 4.5 | $0.00010 | $0.01754 |
Grade A, and why
image-generation-gateways scanned grade A with 1 finding 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 7d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Image generation through gateways
A gateway standardizes account access, not model behavior. Keep gateway, model publisher, model/version, execution path, schema, price, safety behavior, and downstream terms as separate facts in every plan and ledger row.
This skill covers three current multi-model serverless gateways:
- fal.ai Model APIs: direct or persistent queue calls to model endpoint IDs, with queue status, cancellation, and signed webhooks.
- Replicate predictions: prediction resources around official, community, marketplace, or version-pinned models.
- Together AI serverless images: a synchronous OpenAI-compatible image endpoint spanning models with different parameter subsets.
These gateways were selected because their first-party contracts expose three materially different operating patterns. Do not add another gateway merely because it offers the same model name. Research its control plane, billing unit, data path, lifecycle, schema, and terms first.
Volatile facts here were checked 2026-07-10. Use four evidence labels in user-facing work:
- FACT: directly documented by the cited gateway, model publisher, or governing terms.
- PROVIDER CLAIM: a quality, commercial-use, training, security, equivalence, or infrastructure representation that was not independently audited here.
- HEURISTIC: a conservative production practice in this skill, not a gateway limit.
- UNKNOWN: public first-party evidence was insufficient; resolve through the account, contract, DPA, model publisher, or support.
Build the routing record before code
Capture a signed-off record with:
- production intent and image acceptance tests;
- gateway and account/project;
- exact endpoint/model ID, publisher, official/community/partner status, and version policy;
- schema URL or API-discovered schema plus retrieval time and hash;
- complete input fields, reference provenance, output count/format/size, safety controls, and seed;
- execution path: sync, queue/poll, or webhook;
- billing unit, unit price snapshot, estimated maximum, credits/discounts, and approver;
- input/output rights, model terms, gateway terms, downstream processor/data path, retention, training setting, and region;
- artifact destination, byte/pixel limits, provenance fields, and deletion schedule;
- retry, reconciliation, cancellation, and failover policy.
What ships with it
3 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.

image-generation-gateways is a skill published in the GitHub repository calesthio/generative-media-skills (170 stars, last pushed 1mo ago), licensed MIT. It adds 100 tokens to every session and 17,536 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
