What it does
Product Design And UX is an agent skill from magnus919/agent-skills. Define user-facing product behavior from validated evidence and approved scope. Use for information architecture, task flows, state and recovery models, interface contracts, usability-study plans, interaction-pattern tradeoffs, AI recommendations and generated outputs, uncertainty, human control, feedback, or engineering UX handoffs. Use after product discovery and product decisions; route WCAG/ARIA conformance work to web-accessibility and formal software specifications to spec-driven-development. Do not use…
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 28 other files, including reference files (for example `README.md`, `evals/business-app-rubric-challenges.md` and `evals/evals.json`). Compatibility notes: Works with any agent framework supporting the Agent Skills format; no design tool, frontend framework, or proprietary service required.
It sits in Frontend & Design, covering Accessibility, UX design and Spec-driven development. The repository describes itself as: Curated collection of AI agent skills for Hermes and other agent frameworks. The licence is MIT.

What it can do on your machine
Read from SKILL.md and the folder at commit 22b4723. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Works with any agent framework supporting the Agent Skills format; no design tool, frontend framework, or proprietary service required.
From compatibility in the SKILL.md frontmatter.
Context cost
Product Design And UX loads about 2.2k tokens when it runs, and up to ~16k if it reads all its reference files. Until then it costs about 153 tokens; SKILL.md has 780 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Product Design and UX
Turn validated evidence and chosen scope into observable behavior people can complete and recover from. Design the interaction, not the brand, pixels, CSS, component implementation, or a particular tool.
Entry Check
Confirm the approved scope, outcome, users or roles, evidence links, constraints, measurable experience goals, and open product decisions. Record missing inputs rather than inventing them.
- Need stakeholder evidence, validation, or raw research? Use product-discovery.
- Need prioritization, scope, or why a feature is being built? Use product-methodology.
- Need WCAG, ARIA, native semantics, or accessibility testing depth? Use web-accessibility.
- Need an approved interaction contract translated into a software specification and delivery gates? Use spec-driven-development.
- Need to design an AI-assisted, generated, predictive, recommendatory, or tool-using interaction? Read AI interaction and uncertainty and use the AI interaction contract alongside the general contract. Route model evaluation and observability design to agent-evals-and-observability, governance to ai-governance, runtime authority to agent-production-operations, product measurement to product-analytics-and-measurement, accessibility to web-accessibility, and cost/value decisions to ai-operating-economics.
- Need a person to delegate to an agent they use outside the product, then inspect or resume the work across apps? Read external agent interactions and fill the external agent handoff alongside the AI interaction and task-flow contracts. Do not assume the product hosts that agent or can see its private conversation.
Workflow
- Trace each outcome and design decision to evidence with
templates/outcomes-to-design.md. Optional personas or jobs must change a decision and cite evidence; do not create decorative demographics. - Establish information architecture from goals, content objects, terminology, permissions, findability, and service context. Read
references/information-architecture.md. - Define consequential labels, instructions, status, errors, and completion content; review the task's memory, choice, switching, interruption, and recovery demands. Use heuristics to generate testable questions, not verdicts. Read
references/content-and-cognitive-demand.md. - Model important tasks across every participating role, including recipient-side work after a handoff. Stop at the intended user outcome, not merely submission, delivery, or an intermediate status. Include decisions, alternatives, interruption, re-entry, cancellation, recovery, irreversible actions, side effects, permission changes, and completion evidence. Read
references/task-flows-and-state-models.mdand usetemplates/task-flow-state-model.md. - Inventory only states forced by the flow, data, permissions, connectivity, and risk. Record risky omissions. Use
templates/screen-state-inventory.md. - Write framework-neutral contracts for content, controls, accessible interaction requirements, actions, transitions, persistence, permissions, responsive/reflow behavior, telemetry, and open decisions. Read
references/interface-contracts-and-responsive-behavior.mdand usetemplates/interface-contract.md. - Treat patterns as hypotheses. Compare alternatives, tradeoffs, evidence, and disconfirming conditions with
references/interaction-pattern-selection.md. - Plan or synthesize only authorized usability work. Read
references/usability-testing-and-privacy.md; usetemplates/usability-study.md. Never invent participants, consent, observations, quotes, or results. - Produce an engineering handoff with observable acceptance evidence, dependencies, owners, gates, and deployed-boundary verification. Read
references/engineering-handoff.md; usetemplates/engineering-handoff.md. Hand approved behavior to spec-driven-development.

Guardrails
- Accessibility is designed throughout, but WCAG/ARIA/native-semantics and testing depth remain with
web-accessibility. - Specify behavior under relevant width, zoom/reflow, text expansion/localization, orientation, input modes, reduced motion, degraded connectivity, interruption, and re-entry. Do not use device breakpoints as the model.
- Use synthetic fixtures such as
sample-user@example.testandINV-DEMO-042; never request real credentials, payments, financial access, or secrets for an unsafe prototype. - A finding from usability work is bounded evidence, not accessibility conformance, population prevalence, analytics, or outcome proof.
- AI output, confidence, explanation, citation, or user feedback is not proof of correctness by itself. Record the evidence boundary and route model-quality and statistical questions to the owning specialist.
Completion
Stop when every in-scope behavior has traceable evidence, an applicable state/recovery model, observable acceptance criteria, and either a resolved decision or an owner and resolution gate. Report limitations and untested risks rather than filling gaps with assumptions.
Embedded business-app example
When designing an agent inside an existing task surface, read the equipment-loan worked example. It fills the existing AI interaction, task-flow, and engineering-handoff contracts from recommendation through confirmed effects and recovery; treat its acceptance probes as synthetic design fixtures, not observed usability results.
For executable AI recommendations, re-check current permission, record revision, policy, inventory, and the approved action digest at execution. An approval-time check alone is insufficient. After an uncertain command outcome, query the persisted command ID before any retry; do not create a new reservation ID or repeat a confirmed side effect. Show partial effects separately.
