Development
Explores a website interactively via the robomotion-browser-mcp server to discover selectors, record action sequences, capture network traffic, and produce a JSON flow sequence that maps to Robomotion SDK TypeScript. Use when the user says "explore this page", "find the selector for X", "record the login flow", "what API does this page use", or before writing ANY `Core.Browser.*` flow. Pairs with `reversing-network` when the captured traffic reveals a clean API.
Provides domain knowledge and guidance for Flare FAssets—wrapped tokens (FXRP, FBTC, etc.), minting, redemption, agents, collateral, and smart contract integration. Use when working with FAssets, FXRP, FBTC, FAssets minting or redemption, Flare DeFi, agent/collateral flows, or Flare Developer Hub FAssets APIs and contracts.
Use this skill whenever implementing or debugging Biome formatter behavior, IR composition, node rules, layout selection, source-comment handling, verbatim formatting, idempotency, internal specs, or Prettier comparison. Do not use it for generic snapshot commands or parser changes.
Use when building Document Controllers in a custom Frappe app: file creation, lifecycle hooks, validation, autoname, submittable workflows, controller override, child table controllers, flags system, migration from hooks.py and Server Scripts. Keywords: how to implement controller, which hook to use, validate vs on_update, override controller, submittable document, autoname, flags, extend_doctype_class, controller testing, child table controller, which hook to use, when does validate run, how to override save, document lifecycle.

Use BEFORE any rename, removal, required-field change, or other contract-breaking edit to a config on a Datex Studio branch. Runs reverse-trace to find all callers, categorizes them (including write-side vs read-side for storage-shape changes), and presents a safety gate. Generic — works for any config type (functions, datasources, flows, storages, type definitions, reports, etc.). Also invoke when a calling skill asks you to "audit all callers" or "verify a contract change is safe" before proceeding.
Receive and verify Linear webhooks. Use when setting up Linear webhook handlers, debugging Linear signature verification, or handling Linear issue tracking events like Issue, Comment, Project, Cycle, IssueLabel, and IssueSLA create/update/remove actions.
Interpret and use `mcpjam` probe, doctor, OAuth, XAA (Cross-App Access / ID-JAG), apps conformance, tools, resources, and prompts output conservatively against MCP 2025-11-25.

Drafting Python Enhancement Proposals (PEPs) — proposing a Python language feature, a standard library change, an interoperability standard, or an informational/process document for the Python community. Covers all three PEP types (Standards Track, Informational, Process): choosing the right type, scaffolding a valid reStructuredText pep-NNNN file, filling each required section to the acceptance bar, linting the headers, and navigating the sponsor / submission / Steering Council review process. Trigger on "write a PEP", "draft a PEP", "propose a Python feature", "create a Python Enhancement Proposal", "PEP template", or when someone is preparing a proposal for the Python Discourse or python-dev. Use it even if the user only says "PEP" or doesn't mention reStructuredText — the headers, sections, and process are exactly what trips PEP authors up.
Modern Python development with uv, the fast Python package and project manager. Covers project management (uv init, uv add, uv sync, uv lock), virtual environments, Python version management (uv python install/pin), script runners (uv run), tool management (uvx), workspace support for monorepos, and publishing to PyPI.

Also trigger when you see patterns like "setState inside useEffect", "effect chains", "derived state in effect", or "notify parent in effect". Covers 12 specific scenarios where Effects are unnecessary or misused, with correct alternatives. Even if the useEffect looks reasonable at first glance, consult this skill to verify it's truly needed.
Draft or revise ax release announcements and website changelog pages. Triggers when the user says "write release notes", "draft release announcement", "prepare changelog", "release page", "version page", "what changed in vX.Y.Z", "generate announcement for vX.Y.Z", or asks for a release narrative. Uses Release Please range evidence, git changed files/commits, and ax sessions/recall to explain how the release got there. Do NOT trigger for ordinary commit messages or unrelated docs.
Search before you write, sweep before you finish. Use BEFORE creating any utility, type, schema, component, hook, constant, module, or package; BEFORE hardcoding a literal that may be an exported constant; when about to copy-paste similar code; and as a completion gate over every file the task touched, not just the diff.

Covers Humble, Iron, Jazzy, and Rolling distributions.
Make Sentry stack traces readable—upload source maps for JavaScript/TypeScript, or debug files for native and mobile (dSYM, ProGuard/R8, NDK symbols, Dart obfuscation maps, .NET PDBs). Use when frames in Sentry show minified names, bundled paths, hex addresses, “unknown”, or method names with no file/line, instead of your original source.
Audit requirement quality across spec.md, plan.md, and tasks.md for a chosen domain (UX, API, security, performance…). Writes reviewer-owned checklists that test whether requirements are complete, clear, measurable, and consistent—unit tests for the requirements, not for the code
Use when the user is customizing the Spree admin (the `spree_admin` gem) — adding a new resource page, registering a sidebar item, customizing a column in an admin table, overriding a view, scaffolding a new admin section.
