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.

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 | $0.00181 | $0.01657 |
| Opus 5 | $0.00090 | $0.00829 |
| Sonnet 5 | $0.00036 | $0.00331 |
| Haiku 4.5 | $0.00018 | $0.00166 |
Grade A, and why
migrate-waniwani-sdk-0.18-to-0.19 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.
How it starts
The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Migrate @waniwani/sdk 0.18 → 0.19
A self-contained migration for the single hop from 0.18.x to 0.19.x (the first published 0.19 release is 0.19.1; 0.19.0 was never published to npm). Apply it when a project on 0.18 is moving to 0.19. It covers only that jump; for other version boundaries use the matching migrate-waniwani-sdk-<from>-to-<to> skill, or the general procedure in the SDK's changelog.
Precondition: the project is on @waniwani/[email protected]. If it is on an older version, migrate up to 0.18 first (each jump ships its own migration skill); if it is already on 0.19+, there is nothing to do here.
What 0.19 changes
Flow interrupt({ suggestions }) values now also render as clickable pills above the input in the Waniwani chat widget, gated by a named origin list. Almost all of it is additive; the one break:
suggestion.clickedgained a requiredproperties.originfield —"channel" | "page" | "flow" | "followup", reporting which provider supplied the clicked pill. On 0.18.x the payload was{ text, index }. The field is part ofWidgetEventDetail/WidgetEventfrom@waniwani/sdk/chat.
Also shipped (no action required):
SuggestionsConfig.origins(SuggestionOrigin[]) replaces thedynamicboolean on the<ChatEmbed>primitive.dynamicis deprecated but still works:truemaps to every origin,falseto none,originswins when both are set.suggestionOriginson<WaniwaniChat>overrides anddata-suggestion-originson the<script>embed. Default everywhere is["channel", "page", "followup"]— flow-driven pills stay opt-in.- Flow tool results always carry
_meta["waniwani/suggestions"](exported asSUGGESTIONS_META_KEY/SuggestionsMeta). Additive; hosts that ignore_metaare unaffected.
Not affected: reading widget events through onEvent — origin is a new, always-populated field, so existing readers keep compiling and running. Other MCP hosts (ChatGPT, Claude) see no behavior change.
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.

migrate-waniwani-sdk-0.18-to-0.19 is a skill published in the GitHub repository WaniWani-AI/sdk (17 stars, last pushed yesterday), licensed MIT. It adds 181 tokens to every session and 1,657 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings.
