Skill Compose is an open-source platform for building and running AI agents that use modular skills. It is intended for creating skill-powered agents without workflow graphs or a command-line interface, and the catalogue skills are examples of those agent capabilities.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00069 | $0.01878 |
| Opus 5 | $0.00034 | $0.00939 |
| Sonnet 5 | $0.00014 | $0.00376 |
| Haiku 4.5 | $0.00007 | $0.00188 |
Grade A, and why
copywriting 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 5d 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 — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Brand Copywriting Constraints
A lightweight constraint reference for brand copy. The LLM already knows how to write — this skill provides the specific limits, structures, and rules that turn generic copy into brand-precise copy.
TAGLINE RULES
A tagline is the single most compressed expression of a brand. It appears on logos, business cards, social covers, and packaging.
Structure
- Length: 3-5 words maximum. No exceptions.
- No period at the end (taglines are not sentences).
- No brand name in the tagline (it appears alongside, not inside).
Approved Patterns
| Pattern | Example | When to Use |
|---|---|---|
| Imperative verb | "Think Different" | Action-oriented brands |
| Statement | "Beauty Outside. Beast Inside." | Dual-nature positioning |
| Noun phrase | "The Ultimate Driving Machine" | Category ownership |
| Question | "What's in Your Wallet?" | Engagement / curiosity |
Memorability Test
Before finalizing, check:
- Can you say it in one breath without pausing?
- Does it sound natural spoken aloud, not just on paper?
- Does it work without context — would someone understand the vibe even without seeing the brand?
Avoid
- Generic superlatives ("The Best", "World-Class", "Premium")
- Puns that require explanation
- Industry jargon the target audience wouldn't use casually
- More than one clause or conjunction
BRAND VOICE SPECTRUM
Define the brand voice along four axes. Each axis is a continuum — pick a position for the brand.
| Axis | Left Pole | Right Pole | What It Governs |
|---|---|---|---|
| Formality | Formal | Casual | Vocabulary, contractions, sentence structure |
| Tone | Serious | Playful | Humor, metaphor, punctuation style |
| Complexity | Technical | Accessible | Jargon level, explanation depth |
| Energy | Reserved | Bold | Exclamation, caps, directness |
Example Voice Profile
Brand: Aether Coffee
Formality: ████████░░ (8/10 — leans formal, no slang)
Tone: ███░░░░░░░ (3/10 — mostly serious, quiet confidence)
Complexity: ██░░░░░░░░ (2/10 — very accessible, no jargon)
Energy: █████░░░░░ (5/10 — balanced, neither loud nor whispered)
Voice summary: Calm authority. Speaks like a knowledgeable barista
who respects your time — precise, unhurried, no fluff.
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.

copywriting is a skill published in the GitHub repository dp-archive/archive (1,106 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 69 tokens to every session and 1,878 once invoked, about $0.0003 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.
