Compares coding agents like Claude Code and Aider on custom YAML-defined codebase tasks using git worktrees, measuring pass rate, cost, time, and consistency.
Designs and optimizes AI agent action spaces, tool definitions, observation formats, error recovery, and context for higher task completion rates.
Designs, implements, and audits WCAG 2.2 AA accessible UIs for Web (ARIA/HTML5), iOS (SwiftUI traits), and Android (Compose semantics). Audits code for compliance gaps.

Session files use kebab-case in the Sessions/ folder:
Sessions/YYYY-MM-DD-brief-description.md
Example: Sessions/2026-03-02-docker-compose-setup.md
start - Begin a new session with timestamp and objectiveupdate - Add content to current sessionend - Finalize session with summary and learningslink - Cross-reference with projects or daily notesCheck if session file exists:
obsidian read path="Sessions/YYYY-MM-DD-brief-description.md" 2>/dev/null
Empty output = file does not exist yet.
Create new session file (if it doesn't exist):
obsidian create path="Sessions/YYYY-MM-DD-brief-description.md" content="---\ntype: session\nstatus: in-progress\ndate: YYYY-MM-DD\n---\n\n# Session Title\n"
Append session content (if it already exists):
obsidian append path="Sessions/YYYY-MM-DD-brief-description.md" content="## HH:MM - Session Title\n..."
Set metadata on finalize:
obsidian property:set path="Sessions/YYYY-MM-DD-brief-description.md" name="status" value="complete"
