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 | $0.00172 | $0.01604 |
| Opus 5 | $0.00086 | $0.00802 |
| Sonnet 5 | $0.00034 | $0.00321 |
| Haiku 4.5 | $0.00017 | $0.00160 |
Grade A, and why
migrate-waniwani-sdk-0.17-to-0.18 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 — 118 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Migrate @waniwani/sdk 0.17 → 0.18
A self-contained migration for the single hop from 0.17.x to 0.18.0. Apply it when a project on 0.17 is moving to 0.18. 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 0.17 first (each jump ships its own migration skill); if it is already on 0.18+, there is nothing to do here.
What 0.18 changes
The generic funnel events quote.requested, quote.succeeded, quote.failed, and purchase.completed are removed from EVENT_TYPES and the TrackEvent union. They predate the typed revenue taxonomy (price_shown, prices_compared, option_selected, lead_qualified, converted), which models the same funnel stages with typed properties and flat track.* helpers.
Removed with them:
- The type exports
QuoteSucceededPropertiesandPurchaseCompletedProperties(from@waniwani/sdkand@waniwani/sdk/mcp's tracking surface) - The legacy input fields
quoteAmount,quoteCurrency,purchaseAmount,purchaseCurrencyonLegacyTrackEvent
Not affected: link.clicked (and LinkClickedProperties, legacy linkUrl) stays a first-class event, on both track() and the chat widget's separate host-page onEvent channel.
Unlike the 0.17 hop, this break is visible to tsc: every removed event name and type import surfaces as a type error after the bump, so the compiler output is the complete call-site list.
Procedure
- Bump the dependency.
bun add @waniwani/sdk@^0.18.0 - Collect the call sites. Run the type checker and/or grep:
bun run typecheck rg "quote\.requested|quote\.succeeded|quote\.failed|purchase\.completed|QuoteSucceededProperties|PurchaseCompletedProperties|quoteAmount|purchaseAmount" - Apply the rewrites below to every hit. The
tracksurface is the same on all four clients (serverwaniwani(), scopedcontext.waniwani,useWaniwani(),chat.track), so the rewrites are identical everywhere. - Verify — this is the completion check.
bun run typecheck bun test - Report which rewrite each call site took.
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-0.17-to-0.18 is a skill published in the GitHub repository WaniWani-AI/sdk (17 stars, last pushed yesterday), licensed MIT. It adds 172 tokens to every session and 1,604 once invoked, about $0.0009 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.
Other skills, from other repositories
add-export
Add a new subpath export to the @cyanheads/mcp-ts-core package. Use when creating a new public API surface that consumers import from a dedicated subpath (e.g., @cyanheads/mcp-ts-core/newutil).
fluent-development
This skill should be used when the user asks to "build a fluent app", "create a servicenow app in typescript", or mentions "servicenow sdk", "now-sdk", "fluent", "scoped app as code", or "pro-code development" — or when the working directory contains a now.config.json or .now.ts files.
implementing-jsc-classes-rust
Creates JavaScript classes using Bun's Rust bindings generator (.classes.ts). Use when implementing new JS APIs in Rust with JSC integration, prototypes, or constructors.
sdk
Guide users building apps, scripts, CI pipelines, or automations on top of the Cursor TypeScript SDK (@cursor/sdk). Use when the user mentions integrating, installing, or writing code against the Cursor SDK; says Agent.create, Agent.prompt, Agent.resume, agent.send, run.stream, CursorAgentError, or @cursor/sdk; asks…
typescript-lsp
Search TypeScript SYMBOLS (functions, types, classes) - NOT text. Use Glob to find files, Grep for text search, LSP for symbol search. Provides type-aware results that understand imports, exports, and relationships.
kernelcad-authoring
Author or modify kernelCAD models in TypeScript. Scripts live in .kcad.ts files; the kernelCAD CLI (kernelcad evaluate and kernelcad export stl|step|dxf|3mf|glb -o ) executes them via an OpenCASCADE WASM kernel.
