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 | $0.00037 | $0.00198 |
| Opus 5 | $0.00018 | $0.00099 |
| Sonnet 5 | $0.00007 | $0.00040 |
| Haiku 4.5 | $0.00004 | $0.00020 |
Grade A, and why
omd:migrate 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 12d 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.
What it actually says
omd:migrate — catalog write safety gate
CORE_V2_CATALOG_WRITE_BLOCKED
Do not mutate web/references/<id>/DESIGN.md, its frontmatter, numbered
sections, verification footer, or mirrors. Those files remain readable during
the migration window, but creating more legacy bytes would violate the Core v2
dual-read/single-write contract.
For a provider-free assessment, use the Core migration auditor in check mode.
Do not adopt or overwrite its staged result. A migration candidate keeps the
source DESIGN.md canonical until a graph-backed catalog writer, migrated
consumers, evidence binding, and dropped_segments=0 acceptance ship together.
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.

omd:migrate is a skill published in the GitHub repository kwakseongjae/oh-my-design (498 stars, last pushed 4d ago), licensed MIT. It adds 37 tokens to every session and 198 once invoked, about $0.0002 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.
