newsletter

newsletter is a command for Claude Code from arome3/code-to-content. It costs 8 tokens per session (583 once invoked), scanned A, original, MIT.

A command for turning updates from a software project into a newsletter issue. It can examine the project files and recent Git history for material to include.

In plain words
What is it for?
It is for creating newsletter drafts from project updates, code changes, commits, specifications, support discussions, or rough notes.
Why use it?
It helps turn technical changes into a readable update instead of requiring someone to start the newsletter from a blank page. It can also look for a distinctive point of view or supporting raw material.

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

newsletter 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 4d 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.

Generate Newsletter Issue

Create a newsletter issue featuring updates from the provided project.

Differentiation Discovery (offer; never blocking): Before generating, offer to make this unmistakably theirs — ask for the WHY (the thesis/stakes), one defensible opinion, a road not taken, or a rough draft to polish ("write it ugly; I'll keep your voice"). Rank raw material (Slack threads, support tickets, a voice-memo transcript) above clean specs. If declined, proceed on code alone and flag Distinctiveness: AT RISK. At delivery, run the swap-the-name test + AI-tells blocklist from references/differentiation.md.

Process

  1. Analyze Recent Changes Analyze the codebase Claude-natively (read dependency files, detect architecture, grep story hooks like TODO/FIXME, mine git log) — see references/analysis-prompts.md. No scripts required. Also examine recent git history for story-worthy commits.

  2. Load Skill Context Read these files:

    • skills/code-to-content/SKILL.md
    • skills/code-to-content/references/differentiation.md (WHY / opinion / roads-not-taken)
    • skills/code-to-content/references/newsletters.md
    • skills/code-to-content/assets/templates/newsletter.md
  3. Identify Newsletter Format Ask the user which format fits their update:

    • Build Log: Active development (shipped, learned, next)
    • Deep Dive: After completing significant feature
    • Lesson Learned: After resolving a challenge
    • Milestone Update: Reached a significant goal
  4. Extract Content Elements

    • Featured item (main update or insight)
    • Quick hits (3-5 smaller updates)
    • Code snippet or visual if applicable
    • Personal reflection or lesson
    • What's next / roadmap tease
  5. Generate Newsletter Include:

    • Subject line (under 50 chars, creates curiosity)
    • Preview text (120-160 chars)
    • Personal opening hook (conversational)
    • Featured section with unique commentary
    • Quick hits with your perspective (not just changelog)
    • Engaging closing with CTA

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.
