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 | $0.00042 | $0.00194 |
| Opus 5.5 | $0.00017 | $0.00078 |
| Sonnet 5.5 | $0.00008 | $0.00039 |
| Haiku 4.5 | $0.00004 | $0.00019 |
Grade A, and why
wrdn-effect-atom-reactivity-keys 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 1mo 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.
This is a copy
100% identical to wrdn-effect-atom-reactivity-keys — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Effect-atom write mutations must say which reads they invalidate.
Fix Shape
- Find the
useAtomSet(...)write mutation call. - Add
reactivityKeysto the mutation payload at the call site. - Use the narrowest keys that cover the rows/lists affected by the write.
- Keep read-only probe/preview OAuth flows out of this pattern.
- If the mutation should update UI immediately, check whether
wrdn-effect-atom-optimisticalso applies.
Good
await updateSource({
params: { scopeId, sourceId },
payload,
reactivityKeys: [["sources", scopeId]],
});
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.

wrdn-effect-atom-reactivity-keys is a skill published in the GitHub repository adarshp14/relay (0 stars, last pushed 4mo ago), licensed MIT. It adds 42 tokens to every session and 194 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings.
