CustomerNewsletter: Skill for Claude Code

.github/skills/curator-notes/SKILL.md

curator-notes is a skill for Claude Code, Codex from briancl2/CustomerNewsletter. It costs 96 tokens per session (1,797 once invoked), scanned A, original, MIT.

A newsletter-pipeline step that turns a curator’s monthly notes—such as rough links, text hints, and priorities—into organized content and editorial signals. Editorial signals are guidance about importance, themes, or internal context.

In plain words
What is it for?
Use it to process curator notes between discovery and newsletter curation, producing processed items and editorial guidance.
Why use it?
It turns an informal brain dump into material that later newsletter selection can use, while filtering private or internal links appropriately.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

curator-notes scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Curator Notes Processing

Process the human curator's monthly notes file into pipeline-ready content and editorial signals.

Quick Start

  1. Check for workspace/curator_notes_YYYY-MM.md (or known variants)
  2. If no file exists, skip this phase entirely -- pipeline continues normally
  3. Parse and classify every item using the link type taxonomy
  4. Filter: internal links become editorial signals; public links get visited
  5. Output processed items + editorial signals
  6. Items feed into Phase 3 curation alongside Phase 1C discoveries

Inputs

  • Curator notes file (optional): workspace/curator_notes_YYYY-MM.md
    • May also appear as: workspace/<month>.md, workspace/<Month>.md, workspace/Jan.md, etc.
    • Check for any .md file in workspace/ that looks like a brain dump of links
  • Phase 1C Discoveries: For cross-reference (avoid duplicates)

Output

  • workspace/curator_notes_processed_YYYY-MM.md -- Items in universal extraction format, ready for Phase 3
  • workspace/curator_notes_editorial_signals_YYYY-MM.md -- Priority hints, theme suggestions, internal context

Core Workflow

Step 0: Locate the Notes File

Check these paths in order:

  1. workspace/curator_notes_YYYY-MM.md (canonical)
  2. workspace/<Month>.md (e.g., workspace/Jan.md, workspace/February.md)
  3. Any .md file in workspace/ containing 3+ URLs that isn't a pipeline output

If no file found: SKIP. Output nothing. Pipeline continues.

Step 1: Parse and Classify

For each line/item in the notes file, classify into one of these types:

Type Detection Pattern Action
GitHub Changelog github.blog/changelog/ PROCESS: visit URL, extract item
GitHub Blog github.blog/news-insights/ or github.blog/ai-and-ml/ PROCESS: visit URL, extract item
VS Code Release Notes code.visualstudio.com/updates/ PROCESS: visit URL, extract features
Microsoft DevBlog devblogs.microsoft.com/ PROCESS: visit if GitHub-specific
Community resource github.com/<user>/, personal sites, awesome-lists PROCESS: visit URL, extract description
VS Code extension marketplace.visualstudio.com/ PROCESS: visit URL, extract description
YouTube video youtube.com/watch, youtu.be/ PROCESS: visit, extract title and context
Event registration registration.goldcast.io/, github.com/resources/events/ PROCESS: extract event details
Named feature hint Text line without URL referencing a product name SIGNAL: flag as editorial priority
Internal link github.slack.com/, docs.google.com/, github.com/github/ (private repos), thehub.github.com/ SIGNAL: translate topic to public reference
Industry content hbr.org/, substack.com/, medium.com/, martinfowler.com/, analyst reports SIGNAL: framing context only
Competitor content blog.cloudflare.com/, sonarsource.com/, etc. SIGNAL: competitive context only
Text note (vague) Bare text, no URL, no product name SIGNAL: note for context

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
