Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00125 | $0.02005 |
| Opus 5 | $0.00063 | $0.01002 |
| Sonnet 5 | $0.00025 | $0.00401 |
| Haiku 4.5 | $0.00013 | $0.00200 |
Grade A, and why
newsletter-management 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 13d 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 — 275 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Newsletter Management
Workspace Context
Read bootstrap context before asking questions: strategy/brand.md for brand, audience, offer, channels, tools, constraints, and metrics; about/me.md for personal voice; content/ideas.md and content/calendar.md for content planning. Use legacy product-marketing context files only as fallback. Save generated drafts to content/<platform>/drafts/YYYY-MM-DD_short-topic-slug.md, and route durable learnings back to strategy/brand.md, about/me.md, or content/ideas.md.
Operating Contract
This skill is self-contained for its frontmatter scope: use its local instructions, references, scripts, and assets as the playbook; ask only for missing task-specific inputs; hand off to adjacent skills instead of expanding scope; and return an actionable artifact, decision, plan, draft, or diagnostic.
Build, curate, and grow recurring newsletters that create genuine value for subscribers.
The 6 Newsletter Formats
1. Curated / Link Roundup
Share 5–15 curated links with commentary per link.
Structure:
- Opening: Personal note or insight
- 5–10 curated links with your take (not just a description)
- Closing: Personal sign-off
## This Week's Top Picks
### [Article Title](url)
One to three sentences on why this matters and what the reader
will get from it. Add your take — don't just describe.
Best for: Building authority, staying top-of-mind | Time: 30–45 min
2. Story-Driven
Tell a personal story that teaches a lesson.
Structure: Hook → Story → Lesson → Application → Closing
Best for: Building connection, teaching through narrative | Time: 45–60 min
Example: "How I learned the hard way about delegation"
3. Educational / Deep Dive
Teach a specific concept, framework, or analysis (300–1,000 words).
Structure: Hook (why this matters) → Concept/Analysis → Examples → Application → Closing
## The Big Story

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.

newsletter-management is a skill published in the GitHub repository manojbajaj95/claude-gtm-plugin (100 stars, last pushed 3mo ago), licensed MIT. It adds 125 tokens to every session and 2,005 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
