Making Content Usable (COGA) - Skill Entry

This SKILL.md is the entrypoint for the Making Content Usable for People with Cognitive and Learning Disabilities (COGA) framework skill used by the Accessibility Planner and the Accessibility Skill Assessor subagent.

COGA is a Working Group Note published by the W3C Cognitive Accessibility Task Force. Unlike the normative WCAG 2.2 success criteria, COGA provides informative design guidance: 53 design patterns are organised into eight user-need objectives that together cover the accessibility needs of people with cognitive, learning, neurological, and age-related impairments. Each pattern describes a user need, suggested design approaches, and evaluation considerations. COGA patterns frequently complement WCAG 2.2 criteria, since several user needs (consistent navigation, clear labels, error prevention, focus support) are partially expressed across both standards.

Licensing posture

COGA is published under the W3C Document License as a Working Group Note. This skill paraphrases pattern intent rather than reproducing the source verbatim, in line with the paraphrase-preferred posture defined in accessibility-license-posture.instructions.md. Every per-objective reference file cites the canonical W3C URL anchor for each pattern, and any future verbatim quotation must carry the W3C copyright attribution line specified in that instruction file.

Pattern roll-up

The table below lists every COGA pattern grouped by objective. The Reference column links into the per-objective reference file using an anchor that matches the section header for that pattern. Total: 53 patterns across 8 objectives.
