Integrate Internet Identity authentication. Covers passkey and OpenID sign-in flows, delegation handling, principal-per-app isolation, and the /.well-known/ii-app-metadata document that shows your app's name, description, and logo on the sign-in screen. Use…
Motoko language pitfalls, modern syntax, and architecture patterns for the Internet Computer. Covers persistent actors, stable types, mo:core standard library, dot notation, mixins, and common compilation errors. Use when writing Motoko canister code, fixing…
Improve an existing skill in the IC Skills repo (skills.internetcomputer.org). Load this skill whenever asked to improve, fix, update, enhance, review, or add content to an existing skill at skills/<skill-name>/SKILL.md — including adding pitfalls, updating…
Design review for existing Motoko backends — judging whether code is well designed, not how to write it. Covers invariants encoded in types (variants over Text, correlated fields, case _ smells), stable vs transient state discipline under enhanced migration,…
Rules for canister code on a cloud engine (CloudEngine subnet, e.g. OpenCloud). Engine canisters hold 0 cycles: never attach cycles you computed: drop `(with cycles = …)` clauses (failure: IC0504). Cross-subnet calls must be bounded-wait and cycle-free…
Deploys a built Internet Computer project to a cloud engine (OpenCloud): link the console identity with `icp identity link web` (defaults to https://opencloud.org; a delegation handoff covers sandboxes the browser cannot reach), run `icp deploy` on the…
Make HTTPS requests from canisters to external web APIs. Covers transform functions for consensus, cycle cost management, response size limits, and idempotency patterns. Use when a canister needs to call an external API, fetch data from the web, or make HTTP…
Add access-controlled, end-to-end encrypted key-value storage to a canister with the vetKeys EncryptedMaps library (ic-vetkeys for Rust and Motoko backends, @icp-sdk/vetkeys for the frontend). Values are encrypted client-side under vetKeys and shared between…
Build vetKeys cryptography on the Internet Computer via the vetKD system API and the ic-vetkeys (Rust, Motoko) and @icp-sdk/vetkeys (frontend) libraries: identity-based encryption (IBE), threshold BLS signatures, timelock encryption, symmetric key derivation,…
Persist canister state across upgrades. Covers StableBTreeMap and MemoryManager in Rust, persistent actor in Motoko, and upgrade hook patterns. Use when dealing with canister upgrades, data persistence, data lost after upgrade, stable storage, StableBTreeMap,…
One-time installer that makes a Claude Code project keep its Internet Computer skills up to date automatically. Sets up a SessionStart hook plus a sync script so .claude/skills/ always mirrors the latest skills published at skills.internetcomputer.org. Use…
Scaffold and build a complete Caffeine app (caffeine.ai) from scratch — the project layout, the caffeine.toml workspace + canister manifests, the mops.toml for the single Motoko `backend` canister, the React/Vite frontend, and the caffeine CLI build loop…
Motoko actor state migration and schema evolution using the mops-managed migration chain (a migrations/ directory of timestamped files). Use when upgrading canisters, changing actor field types, renaming or adding stable fields, deciding implicit vs explicit…
Deep reference for when the Motoko migration chain misbehaves — upgrade compatibility errors you cannot explain, migration files you cannot write, a first migration whose OldActor is non-empty, a project converted from legacy persistence, or a request to…
Query the public REST APIs that power dashboard.internetcomputer.org. Covers canister metadata, ICRC ledger data, SNS data, ICP ledger, and network metrics with cursor-based pagination. Use when fetching canister info, token data, SNS proposals, or network…
Guides use of the icp command-line tool for building and deploying Internet Computer applications. Covers project configuration (icp.yaml), recipes, environments, canister lifecycle, identity management, and bundling a project into a self-contained .icp…
Register and manage custom domains for IC canisters via the HTTP gateway custom domain service. Covers DNS record configuration (CNAME, TXT, ACME challenge), the .well-known/ic-domains file, domain registration/validation/update/deletion via the REST API, TLS…
Deploy a frontend or any static site to the IC with the @dfinity/static-site recipe (the certified-assets canister). Covers icp.yaml recipe config, SPA routing with _redirects, custom headers/CSP with _headers, clean URLs, access protection for private apps,…
Accept, send, and manage ckBTC (chain-key Bitcoin). Covers BTC deposit flow via minter, ckBTC transfers, withdrawal to BTC, subaccount derivation, and UTXO management. Use when integrating Bitcoin, ckBTC, BTC deposits, or BTC withdrawals in a canister. Do NOT…
Call Ethereum and EVM chains from IC canisters (Rust) via the EVM RPC canister using the evm_rpc_client crate. Covers typed API calls, raw JSON-RPC, multi-provider consensus, ERC-20 reads, and sending pre-signed transactions. Use when calling Ethereum,…
Design and deploy multi-canister dapps. Covers inter-canister calls, canister factory pattern, async messaging pitfalls, bounded vs unbounded wait, and 2MB payload limits. Use when splitting an app across canisters, making inter-canister or cross-canister…
Display a human-readable summary of a canister's interface given its mainnet canister ID or a human-readable name. Like --help but for canisters. Only for mainnet canisters — for local canisters, read the generated .did file in your project directly.
Configure and launch an SNS DAO to decentralize a dapp. Covers token economics, governance parameters, testflight validation, NNS proposal submission, and decentralization swap. Use when launching an SNS, configuring tokenomics, or setting up DAO governance…
