Daily Briefing

Step 1: Search for Today's AI News

Run parallel web searches across these categories:

Step 1b: Check Official Changelogs & Release Notes

In addition to web searches, use WebFetch to check these official changelog pages. Extract only entries dated today — ignore all other dates.

Rules:

• Fetch each page and scan for entries matching today's date (any format: YYYY-MM-DD, Month DD, YYYY, MMM DD, etc.).
• If a page is unreachable, skip it — do not block the briefing.
• Only include items clearly dated today. Do NOT include prior days' entries.
• Merge findings into the matching topic section (e.g., Claude Code → "Claude Code / Anthropic", Copilot → "AI Coding IDEs").
• Deduplicate against web search results — keep the more detailed version.
• If no changelogs have today's entries, move on.

Step 2: Deduplicate Against Previous Briefing

Compare search results against the previous briefing content. Only include stories that are:

• New since the last briefing
• Significant updates to previously covered stories
• Breaking news from today

Step 3: Create or Update Notion Page

CRITICAL: Never create a duplicate page. Use the PAGE_EXISTS result from Step 0b to decide:

If PAGE_EXISTS = true (page for today already exists)

Use mcp__notion__notion-update-page with the page ID from Step 0b to update the existing page. Replace the content with the new briefing. Update the Topics count property.

If PAGE_EXISTS = false (no page for today)

Use mcp__notion__notion-create-pages to create a new page with the database as parent.

• Set properties: Date = today's date title, Status = "Complete", Topics = number of sections.
• Format content with numbered ## N. Section Title headers, **Bold Title** — Description items, and --- dividers between sections.

Do NOT re-query Notion here. Trust Step 0b's result. Re-querying risks false negatives from title format mismatches or API timing, which causes duplicate pages.

Content Format

Each section should follow this pattern:

## N. Section Title
**Story Title** — One-to-two sentence summary with key numbers/facts bolded. Include source links where available.
---

Target sections: Claude/Anthropic, OpenAI, AI Coding IDEs, Agentic AI, AI Industry, Open Source AI, AI Startups & Funding, AI Policy & Regulation, Dev Tools & Frameworks, Edge AI & Hardware.

Only include sections that have new content. Do not create empty sections.

Step 4: Generate Teams Adaptive Card JSON

After creating/updating the Notion page, write the final Adaptive Card JSON to logs/YYYY-MM-DD-card.json. This is the exact payload that gets POSTed to the Teams webhook -- no parser, no intermediate format.

Use the Write tool to save the file. Use the template below, replacing the placeholder values. The notify script (notify-teams.sh / notify-teams.ps1) will POST this file as-is.

Do NOT post the card to any webhook yourself. Only write the JSON file. The calling script handles delivery.

CRITICAL RULES — the card MUST match the template below exactly:

• The file must be valid JSON. No trailing commas. No comments.
• Total file size must be under 24KB (Teams limit is 28KB; leave 4KB headroom).
• All text must be ASCII-safe. Use -- not em dashes. Use straight quotes. No Unicode symbols in bullet text.
• One bullet per story, max ~200 chars each. Two sentences is fine if the story warrants it. Plain text only in bullets.
• Aim for 4-6 bullets per section when there is enough news. Do not pad thin sections — 2-3 bullets is fine if that's all there is.
• Sources are clickable markdown links: [Title](url) -- Adaptive Cards support this in TextBlock.
• Keep it professional and scannable. The card should look polished in a Teams channel.

NON-NEGOTIABLE STRUCTURAL REQUIREMENTS — do NOT invent your own layout:

• Header: MUST be a Container with style: "emphasis", bleed: true, containing a ColumnSet with title/date on the left and story/topic counts on the right. Do NOT use a plain TextBlock for the header. Do NOT add emoji to the header.
• Sources: MUST be a Container with style: "emphasis" at the bottom of the body, with pipe-separated clickable links in a single TextBlock. Do NOT omit the sources section.
• Action button: MUST use "title": "Open Full Briefing in Notion" with "style": "positive". Do NOT shorten to "View in Notion" or omit the style.
• Bullets: Each bullet MUST be its own separate TextBlock with "- " prefix. Do NOT put multiple bullets inside a single TextBlock using \n\n or • — Teams renders them on one line. One TextBlock per bullet, no exceptions.

          }
        ]
      }
    }
  ]
}

Step 5: Generate Obsidian Markdown (if vault configured)

Check if the AI_BRIEFING_OBSIDIAN_VAULT environment variable is set. If it has a value (e.g., /Users/you/Documents/ObsidianVault), you must generate a markdown file for the Obsidian vault.

Write the file to logs/YYYY-MM-DD-obsidian.md (e.g., logs/2026-03-09-obsidian.md).

CRITICAL RULES — formatting for Obsidian:

1. Frontmatter: Must start with YAML frontmatter containing date, type: briefing, topics (list of top topics), and tags: [ai, news, briefing].
2. Related Topics: After frontmatter, add a blockquote with links to the main topics: > Related topics: [[Topic 1]] · [[Topic 2]].
3. Wikilinks: You MUST wrap key entities (companies, models, concepts) in double brackets [[ ]] to create graph edges.
   • For section headings: ## [[OpenAI]] / [[Codex]]
   • In text: ...announced by [[Anthropic]] today... or ...new benchmark for [[LLMs]]...
4. Structure: Keep the exact same two-tier structure (TL;DR, sections, table) as the Notion page, just with wikilinks added.

Example Obsidian file structure:
