Onboard a developer to an unfamiliar repository, big-picture first. Produces a Purpose/Context section (what the repo is and why it exists), a Big Picture built with C4 diagrams (L1 System Context, L2 Container, optional L3 Component) plus event-reaction flow diagrams for async triggers (stream/queue/schedule/object-event), a Navigating-the-Code section (conventions, lean directory map, testing strategy), a Running-It-Locally checklist with the fast pre-PR loop, a Deploying-It section (deployment model, function/trigger inventory, managed-service graph, envs/secrets, CI/CD), and a Security Posture map — every claim cited to exact files, diagrams before code. Use for "onboard me", "help me understand this repo", "give me an overview", "explain this codebase's architecture", "what architecture pattern does this use", "how is this repo structured", "how do I run this locally", "what's the testing strategy here", "how is this service deployed", "how does CI/CD work here", or "what's the security posture". Read-on
Orchestrate implementation of one hexagonal Rust slice by dispatching agents in the correct order — build the domain core (model + use case + ports) first, then fan out the driven and driving adapters in parallel, then wire bootstrap serially. Use when you want to implement a ports-and-adapters slice with parallel adapter work that does not interfere. Trigger for "implement this slice hexagonally", "build the domain then the adapters in parallel", "scaffold a ports-and-adapters feature end to end". For the layering RULES themselves use rust-hexagonal; this skill is the DISPATCH recipe.
Structure and write user documentation with the Diátaxis framework (Tutorials, How-to guides, Reference, Explanation). Use when documenting content for users, designing the architecture of a docs set, or deciding what kind of doc a piece of content should be. Trigger for: "document this for users", "write a tutorial", "write a how-to guide", "structure our docs", "organize the documentation", "what kind of doc is this", "how should I document X", "audit our docs", "are these docs in the right place". NOT for: API rule extraction from code (use spec-extract), feature specs (use spec-create), or onboarding a developer to a repo (use onboarding).
Design or review Rust services using hexagonal (ports and adapters) architecture with idiomatic ownership, errors, and testing. Use when structuring a Rust project, deciding where a trait or dependency belongs, or auditing layering between domain and infrastructure.
Structure Rust code into cohesive modules and functions. Use when writing new Rust feature code, adding a module or a non-trivial function, deciding how to organize a file, splitting a god-file into a directory module, breaking a long function into an orchestrator plus phase functions, keeping an owned resource (transaction, lock, accumulator) from leaking across boundaries, or reviewing module/function structure. Apply while writing, not only when refactoring. Architecture-agnostic — any Rust code, hexagonal or not.
Interview the user relentlessly about every aspect of a plan, walking down each branch of the design tree and resolving dependencies between decisions one-by-one until a shared understanding is reached. Use when pressure-testing a plan, design, or feature idea before implementation, or before running spec-create. Trigger for "grill me", "interview me about this plan", "poke holes in my design", "challenge my assumptions", "stress-test this approach". NOT for writing code or implementing tasks (use spec-impl).

Use agent-browser CLI for browser automation tasks: UI checks, form testing, screenshots, visual diffs.
Requires: npm install -g agent-browser && agent-browser install
Save screenshots, PDFs and diffs to .claude/local/screenshots/ (unversioned via .claude/ gitignore).
Create the directory before first use: mkdir -p .claude/local/screenshots
agent-browser screenshot .claude/local/screenshots/page.png
agent-browser pdf .claude/local/screenshots/page.pdf
agent-browser diff screenshot --baseline .claude/local/screenshots/before.png -o .claude/local/screenshots/diff.png
agent-browser open <url>agent-browser snapshot (returns elements with refs like @e1, @e2)@refs from the snapshotagent-browser close
@eNrefs are single-use per snapshot. Any click that triggers navigation invalidates all refs. Always callsnapshotagain before the next interaction.
scrollintoview expects a CSS selector, not an @eN ref — use eval instead:
agent-browser eval "document.querySelector('[aria-label=\"Label\"]').scrollIntoView()"
find text/role only supports click and hover as subactions — for fill or other interactions, use snapshot + @refagent-browser open <url> # Navigate to URL
agent-browser close # Close browser

| DO | DON'T |
|---|---|
Call snapshot again after every click, navigation, or DOM mutation | Reuse @eN refs from a previous snapshot — they are invalid after any page change |
Use eval "document.querySelector('...').scrollIntoView()" to scroll to an element | Use scrollintoview @eN — it expects a CSS selector, not a ref |
Use find role/text/label/testid for stable semantic locators when only click or hover is needed | Use find ... fill — find only supports click and hover as subactions |
Create .claude/local/screenshots/ before the first screenshot command | Assume the directory exists |
Call wait --load networkidle after navigation-triggering clicks | Proceed immediately after a click — network may not have settled |
Close the browser with agent-browser close when done | Leave the session open between tasks |
Use this checklist when running a multi-step browser flow:
.claude/local/screenshots/ exists before saving any fileopen <url> called — browser is on the correct pagesnapshot called — you have fresh @eN refssnapshot again before the next interactionwait --load networkidle (or wait --text / wait --url) used after navigation-triggering clicksclose called at the end of the sessionagent-browser open https://example.com/form
