Week 13 weekly briefing (round 2) — 2026-06-21

[Katherine-Peng]

What this is

Scheduled weekly learning briefing run for 2026-06-21, following prompts/weekly-briefing.md.

The current-week pointer is still Week 13 · Multi-agent orchestration (design lens) — no items in Week 13 of the Notion checklist have been checked, so the frontier hasn't advanced since the 2026-06-14 run. The existing "Weekly Picks — Week 13" page was generated 7 days ago (outside the 3-day idempotency window), so this run produced an all-new set of picks rather than skipping.

Notion deliverables (live)

• New child page: Weekly Picks — Week 13 → https://app.notion.com/p/38682e5a5fa381d68fd4d63a0d68a1e4
• One-line @mention comment posted to Katherine on that page (no Google Calendar event, per instruction).

Picks (6 — quality over quantity; cap is 7)

#	Tier	Item	Lane	Score
1	⭐	Anthropic — Effective context engineering for AI agents	Engineering	92
2	⭐	MS Copilot Studio — Multi-agent orchestration patterns	Product	87
3	🟠🔵	Designing the Internet of Agents (HAX) — arXiv 2512.11979	Design	87
4	🟠🔵	Agentic Design Patterns — UI/UX & Human-AI Interaction	Design	80
5	🟠	Aakash Gupta — Practical AI Agents for PMs	Product	76
6	🃏	Mollick — What it feels like to work with Mythos (contrarian)	General	72

Diversity rule satisfied: ≥2 Product, ≥2 Design, ≤2 pure-engineer.

Files changed

• config/previously-recommended.md — logged the 6 new URLs and retroactively logged last week's 7 Week-13 picks (they had never been written to the dedup log).
• logs/run-2026-06-21.md — full run log.

Notes / flags

• Source health: YouTube RSS failed (wholesale 403), blog/Substack feeds + rss2json proxy also 403 — coverage rebuilt via web search. Microsoft Research feed worked directly.
• PushNotification tool unavailable in this environment; notification delivered via the Notion @mention instead.
• Pre-existing merge-conflict markers remain in config/sources.md, config/previously-recommended.md, and prompts/weekly-briefing.md (from an earlier stash) — left untouched, out of scope; flagged for Katherine to resolve.
