Manage Motoko projects with the mops CLI — toolchain pinning, dependency management, type-checking, building, and linting. Use when working with mops.toml, mops.lock, running mops commands, adding/removing packages, pinning moc or lintoko versions, checking…

Make a canister app discoverable to an AI agent from just its URL, including through ICP MCP. Covers publishing a /.well-known/ic-architecture manifest of your canisters — generated at deploy time from real canister IDs via the static-site recipe's presync…

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…

Use when you need to run a command (build, test, tool) inside the IC dev container via ./ci/container/container-run.sh — including on a host that has Docker but not podman (set CONTAINER_RUNTIME=docker) — or when you need to keep a namespace.so devbox awake…

Use when upgrading a Rust crate / third-party dependency to a new version — especially non-trivial bumps where the new version removes previously-deprecated APIs, moves modules into separate crates, renames items, or otherwise has a broad blast radius across…

Use after editing any Bazel file — BUILD.bazel, MODULE.bazel (including bazel/rust.MODULE.bazel), or a .bzl file — to validate the change without paying for a full build, and to auto-format it.

Use this when asked to fix flaky bazel tests.

Use when you need to run a Bazel build or test outside DFINITY's internal infrastructure — i.e. without access to the internal remote cache / remote downloader (bazel-remote.idx.dfinity.network), e.g. on a personal machine, in a sandbox, or for a…

Use this when asked to fix a Bazel build reproducibility / determinism issue — a target whose outputs differ between builds (e.g. across machines, users, or checkout locations), typically because something bakes an absolute build path or a timestamp into an…

Guide the governance backend canister upgrade process — pick RC commit, determine targets, create proposal texts, submit proposals, create forum posts, schedule votes, and update changelogs.

Build and review high-quality technical docs as well as agent instruction files in your repository.

ICP / DFINITY visual design system v2: tokens, color, typography, layout, components, accessibility for DFINITY and Internet Computer surfaces. Pairs with icp-brand-voice. Use when building or reviewing visual surfaces (NNS, ICP.app, Internet Identity,…

ICP / DFINITY positioning, voice, and vocabulary v2 for surfaces under the DFINITY or Internet Computer (ICP) mark. Pairs with icp-brand-design. Use when writing or reviewing copy, UI strings, headlines, hero lines, buttons, errors, release notes, blog posts,…

Operate the MULTI/DEX software factory - a filesystem task queue at tasks/queue with atomic claims, priority-by-rename, operator signal files, and session roles, where every consumer seat is a CLI executor session in its own git worktree with its own isolated…

How to find, wait on, and stop processes on this machine without hanging or killing someone else's work. Read BEFORE writing any pgrep/pkill/ps lookup, before polling for a background job or deploy to finish, before stopping a bot fleet, simulator, or dev…

Build and run the Orbit station configuration audit (`orbit-cli audit`) end-to-end against a live station, including the icp-cli Internet Identity setup that reliably trips people up. Use this whenever the user wants to audit, sanity-check, or security-review…
