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 | $0.00213 | $0.13396 |
| Opus 5 | $0.00106 | $0.06698 |
| Sonnet 5 | $0.00043 | $0.02679 |
| Haiku 4.5 | $0.00021 | $0.01340 |
Grade C, and why
design-md scanned grade C 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 10d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

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

/design-md skill — orchestration body
This skill builds a complete catalog entry through a 5-subagent pipeline with one user checkpoint. The pipeline is heavy (research, drafting, two review loops) so resumability matters: each stage's artifact lives on disk in .claude/cache/design-md/{slug}/ and the next stage reads from there. State is encoded by file presence — no separate state.json needed for v1.
Pipeline shape

Loop termination: design loop is blocking — score must reach 8/10 within 3 iterations or the user decides at the checkpoint. Preview loop is non-blocking — proceed with warning if score < 8 at iteration 3.

What ships with it
5 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.

design-md is a skill published in the GitHub repository CaesiumY/ko-design-md (44 stars, last pushed yesterday), licensed MIT. It adds 213 tokens to every session and 13,396 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it C with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
