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.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Memory Poisoning · line 50 Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.Fix: Protect agent memory and state from modification by untrusted content. Use read-only memory for critical instructions and validate all state changes.
- medium Memory Poisoning · line 157 Skill injects content designed to persist in agent memory or context across interactions. Persistent injection can alter agent behavior long after the initial interaction.Fix: Do not allow untrusted input to persist in agent memory or context. Validate all content before storing and implement memory isolation between sessions.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00104 | $0.01823 |
| Opus 5 | $0.00052 | $0.00911 |
| Sonnet 5 | $0.00021 | $0.00365 |
| Haiku 4.5 | $0.00010 | $0.00182 |
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 7d 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.
Ben's Newsletter Writer
An iterative, creative workflow for writing newsletters in Ben's authentic voice.
Critical Rules
- NEVER output a complete newsletter immediately. This is a step-by-step creative process. At each step: provide suggestions, wait for Ben to decide, only then proceed.
- ALWAYS read the specified context documents at each step. Each step lists REQUIRED READING. Do not skip it.
- Write only from the provided context documents. Do not invent strategies, stories, facts, or stylistic habits not evidenced in the inputs.
Context Documents Location
All documents are in the references/ folder bundled with this skill:
references/01_Ben_Profile_Background.md- Ben's story, credentials, valuesreferences/02_What_We_Do_Offer.md- The offer and value propositionreferences/03_ICP_Ideal_Customer_Profile.md- Target audience detailsreferences/04_Voice_Personality.md- Tone and messagingreferences/05_Newsletter_Strategy.md- Positioning and core beliefsreferences/06_Frameworks_and_Patterns.md- Outline frameworks, subject line and hook patternsreferences/07_Writing_Framework.md- Voice DNA, voice modes, writing method, checklistreferences/08_Newsletter_Examples.md- Real newsletter examples to mimic
Read only the file(s) a step names. Do not read all references up front.
The 7-Step Process
Step 1: Input Analysis
REQUIRED READING: None yet. Just analyze the input.
Determine input type and clarify scope.
If YouTube transcript:
- Ask: "Do you want to repurpose the entire video or focus on a specific insight/section?"
- If specific section: ask which part or let Ben specify
- Extract the core insight(s) from the selected content
If insight/idea:
- Confirm understanding of the insight
- Ask clarifying questions if the insight is vague
Output: Clear statement of the core insight to build the newsletter around.
STOP. Wait for Ben to confirm before proceeding.

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 is a skill published in the GitHub repository naveedharri/benai-skills (61 stars, last pushed yesterday), licensed MIT. It adds 104 tokens to every session and 1,823 once invoked, about $0.0005 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 2026-09-05.
