Research and write professional newsletters. An agent skill from HezaoHezao/poirot.

  • Works in 5 steps: Planning → Research & Curation → Writing → …
  • Tasks that involve Newsletters
  • SKILL.md covers Overview, When to Use, Newsletter Workflow and Newsletter Formats, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Newsletter Generation is an agent skill from HezaoHezao/poirot. Research and write professional newsletters.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content, covering Newsletters. The repository describes itself as: Poirot is a deep research agent kernel built for those who care about how agents are architected. The licence is MIT.

When your agent uses it

  • Tasks that involve Newsletters

Example prompts

  • “/newsletter-generation”

Requirements

  • Pre-approved tools (allowed-tools): web_search, browse_page, write_file, present_files

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Planning
  2. Research & Curation
  3. Writing
  4. Review & Format
  5. Save & Present

What it can do on your machine

Read from SKILL.md and the folder at commit 86bf279. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • web_search
    • browse_page
    • write_file
    • present_files

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Newsletter Generation loads about 1k tokens when it runs. Until then it costs about 17 tokens; SKILL.md has 378 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~17
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Newsletter Generation

Overview

Generates professional, well-researched newsletters combining curated content from multiple sources with original analysis and commentary. Follows modern newsletter best practices (Morning Brew, The Hustle, TLDR, Benedict Evans).

Output is a complete, ready-to-publish newsletter in Markdown.

When to Use

  • User asks to generate a newsletter, email digest, or content roundup
  • User requests a curated summary of news or developments on a topic
  • User wants to create a recurring newsletter format
  • User asks to compile recent developments into a briefing
  • User asks for a "weekly roundup", "monthly digest", or "morning briefing"

Newsletter Workflow

Phase 1: Planning

Identify:

  • Topic(s): main subject(s) of the newsletter
  • Format: daily digest, weekly roundup, deep-dive, industry briefing
  • Audience: technical, executive, general
  • Tone: informative, casual, analytical
  • Length: target word count or item count
Phase 2: Research & Curation

Use web_search + browse_page to gather content:

  1. Search broadly for recent developments on the topic
  2. Fetch full articles with browse_page on promising results
  3. Curate 5-10 items worth featuring — prioritize:
    • Breaking news / announcements
    • Original analysis / thought leadership
    • Data releases / reports
    • Interesting perspectives
  4. Extract key facts from each source: headline, key point, why it matters
  5. Verify claims with a second source where possible
Phase 3: Writing

Structure the newsletter:

markdown
# [Newsletter Name] — [Date]

## This Week's Headline
[1-2 sentence hook for the top story]

---

## Top Stories

### 1. [Headline]
[2-3 sentence summary of the story]
**Why it matters**: [1 sentence on significance]
[Source](URL)

### 2. [Headline]
[...]

### 3. [Headline]
[...]

---

## Quick Hits
- [Brief item with link](URL)
- [Brief item with link](URL)
- [Brief item with link](URL)

---

## Deep Dive: [Topic]
[Longer analysis section on one key topic — 200-400 words.
Original commentary, not just summary. Add your perspective on
what this means for the audience.]

---

## Quote of the Week
> "[Notable quote]" — [Attribution](URL)

---

## Coming Up Next Week
[1-2 sentence preview of expected developments]

---

*Curated by [Agent Name]. [Subscribe](link) | [Archive](link)*
Writing Principles
  • Lead with value: each item should answer "why does this matter to me?"
  • Scannable: headlines + bold key points + short paragraphs
  • Original commentary: don't just summarize — add perspective
  • Attribution: link to every source
  • Consistent voice: match the chosen tone throughout
  • Forward-looking: end with what to watch for
Show full SKILL.md (128 more words)Show less
Phase 4: Review & Format
  • Check all links work
  • Verify facts against sources
  • Ensure consistent formatting (headlines, bullets, spacing)
  • Preview in Markdown renderer if possible
Phase 5: Save & Present

Save to .poirot/outputs/newsletter-{topic}-{YYYYMMDD}.md via write_file. Present via present_files.

Newsletter Formats

FormatItemsLengthCadence
Daily Digest3-5300-500 wordsDaily
Weekly Roundup5-10800-1500 wordsWeekly
Deep-Dive1-31500-3000 wordsIrregular
Industry Briefing5-8600-1200 wordsWeekly/Biweekly

Pitfalls

  • Too many items: 5-10 is the sweet spot. More dilutes value.
  • No original commentary: a link dump isn't a newsletter. Add perspective.
  • Stale news: verify items are recent (within the newsletter's cadence window).
  • No "why it matters": readers skim. Each item needs a significance hook.
  • Inconsistent tone: match the audience. Executive briefing ≠ casual blog.
  • Missing attribution: every claim links to its source.
