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: 2 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 | $0.00121 | $0.01105 |
| Opus 5 | $0.00060 | $0.00553 |
| Sonnet 5 | $0.00024 | $0.00221 |
| Haiku 4.5 | $0.00012 | $0.00111 |
Grade A, and why
marketing-copy 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 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.
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 — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Marketing Copy
Outbound copy reaches people who have no product context and no reason to finish reading. It is also the surface where a disclosure mistake is permanent: a post can be deleted, a screenshot of it cannot. Both facts push the same way, toward concrete claims a reader can check.
This covers copy aimed outward. Product-internal strings and documentation
follow
ux-writing;
matching the author's personal voice is
talk-like-scarletkc.
Disclosure comes first
Decide what may be public before writing, because the draft is where a leak gets normalized.
- Keys, invite codes, and credentials are not copy. Anything that grants access belongs in the channel that distributes it under its own terms, never inline in a public post, and never pasted into a draft "to be removed later".
- An unreleased or unlisted URL stays unlisted. A link that has not been announced is not published just because it resolves. The same applies to endpoints, staging hosts, and pages reachable only by those already told.
- Platform rules bind the copy, not just the account. Each destination has its own limits on what may be promoted, linked, priced, or given away, and they differ between platforms carrying the same post. When a rule makes a detail unpostable, drop the detail; hinting at it obliquely to stay within the letter of the rule is the same violation with worse writing.
- Unshipped work is not a feature. Roadmap items, planned platforms, and anything gated behind review get described as what they are, or left out. Announcing a date creates an obligation the copy cannot see.
When a constraint blocks a detail the requester wanted to include, say which detail and why, and let them decide, rather than quietly dropping it or quietly keeping it.
Claims stay traceable
Take substance from what actually shipped: the changelog, the commit range,
the release notes. Every concrete claim traces to one of those, and an
adjective that carries a claim owes what "adjectives need evidence" in
ux-writing asks of it. What outbound adds is the exchange rate: specifics
beat adjectives at the same length, because a number, a mechanism, or a
before-and-after carries conviction that "greatly improved" cannot, and it
survives a reader who checks.
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.

marketing-copy is a skill published in the GitHub repository scarletkc/agents (206 stars, last pushed 3d ago), licensed Apache-2.0. It adds 121 tokens to every session and 1,105 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 2026-08-30.
