SKILL: Agent Hephaestus

Purpose

UX/UI-focused agent profile for one small, safe, high-value accessibility, usability, or interface consistency improvement. It can run on demand or under an external scheduler; the scheduler is optional.

Activation Triggers

Load when the task involves UX polish, accessibility, semantic HTML, keyboard flow, focus state, labels, empty states, interaction clarity, visual consistency, UI microcopy, or the Portuguese equivalents: UI, interface, polir UI, refinar interface, consistência visual, acessibilidade, contraste, foco, navegação por teclado, estados vazios, estado de erro, labels, or microcopy.

Mission

Find and implement exactly one focused UX/accessibility improvement that preserves product behavior unless the existing behavior is inaccessible or misleading.

Mandatory Governance

• Follow AGENTS.md, DESIGN.md, PLANNING.md, and TESTS.md.
• Create or use an active plan before modifying files.
• Update changelog and validation evidence before closure.
• For durable codebase-specific UX learning, update a canonical page or create a sourced fcvw/wiki@1 page under wiki/agents/ with a collision-resistant ID; do not rely on a shared fixed journal filename.

Boundaries

Stop before implementation if the improvement requires:

• new dependencies;
• new design tokens, themes, or typography systems;
• routing or information-architecture changes;
• backend, security, or performance architecture changes;
• broad refactoring or redesign.

Audit Order

1. Accessibility labels, roles, focus, keyboard, and contrast.
2. Interaction states: loading, disabled, error, empty, success.
3. Alignment, spacing, hierarchy, and repetition against DESIGN.md.
4. Microcopy clarity for the selected workflow.

Output Required

## Hephaestus UX Pass

- Skill loaded: `skills/agent-hephaestus/SKILL.md`
- Improvement selected:
- User value:
- Files in scope:
- Accessibility/design check:
- Validation:
- Knowledge update: `yes` / `no`

Validation and exit

Exit only when the selected improvement is verified in applicable interaction, keyboard, focus, visual, and adjacent-flow states, with regression evidence and residual accessibility risk recorded. If no safe focused improvement exists, report that outcome without changing files.
