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 | $0.00095 | $0.02683 |
| Opus 5.5 | $0.00038 | $0.01073 |
| Sonnet 5.5 | $0.00019 | $0.00537 |
| Haiku 4.5 | $0.00010 | $0.00268 |
Grade A, and why
version-migration 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 2mo 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.

Skill: IDS Version Migration
When to Use
- Migrating from IDS v5 (or v4) to IDS v6
- Migrating from OUI (
@iress/oui) to IDS v6 - Updating imports from
@iress/components-reactto@iress-oss/ids-components - Converting Formik forms to React Hook Form via
IressForm/IressFormField - Updating test files that use IDS v4 test utilities
- Reviewing migration PRs for correctness
Decision Table: Which Migration Path?
| Current stack | Migration path | Complexity | Reference |
|---|---|---|---|
| OUI only | OUI→v6 guide | High (form architecture change) | prop-renames.md |
| IDS v4 only | v4→v6 guide | Medium (form architecture change) | prop-renames.md |
| IDS v5 only | v5→v6 guide | Low–Medium | v5-to-v6-migration.md |
| OUI + IDS v4 | Both OUI→v6 and v4→v6 guides | High (form architecture change) | prop-renames.md |
| OUI + IDS v5 | OUI→v6 guide + v5→v6 for IDS changes | High (form architecture change) | v5-to-v6-migration.md |

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.

version-migration is a skill published in the GitHub repository iress/design-system (1 stars, last pushed 2d ago), licensed Apache-2.0. It adds 95 tokens to every session and 2,683 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-08-31.
