What it does
Audience Segmentation is an agent skill from revfactory/harness-100. Audience segmentation skill used by the analyst and curator agents. Provides subscriber behavior analysis, persona-based content personalization, and segment-specific strategy methodologies. Use for 'audience analysis,' 'segmentation,' 'persona,' 'send optimization,' and similar requests.
Its SKILL.md is about 1.3k 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 licence is Apache-2.0.
When your agent uses it
- Audience analysis
- Send optimization
- Similar requests
Example prompts
- “audience analysis,”
- “segmentation,”
- “persona,”
- “/audience-segmentation”
What it can do on your machine
Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
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
Audience Segmentation loads about 1.3k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 471 words of instructions outside code blocks.
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.

Audience Segmentation — Audience Segmentation Methodology
Specialist audience classification knowledge used by the analyst and curator agents when designing content strategy and A/B tests.
Why Segmentation Matters
Sending the same email to 1,000 subscribers produces content that satisfies nobody on average. Segmentation is the art of deciding "who gets what."
Newsletter Segmentation Model: The BEAR Framework
B — Behavior (Behavior-Based)
| Behavior Segment | Definition | Strategy |
|---|---|---|
| Power Readers | Opened last 5 issues consecutively | Deep content, exclusive resources |
| Occasional Readers | Opened 2–3 out of 5 | Optimize subject lines, keep it concise |
| At-Risk | Missed last 3 consecutive issues | Re-engagement campaign |
| New Subscribers | Joined within last 30 days | Welcome series, best-of curation |
| Click-Active | High link-click rate after opening | Deep-dive content, CTA-focused |
E — Engagement Level
Calculate engagement on a 0–100 score:
Engagement Score = (Open Rate Weight x 40) + (Click Rate Weight x 35) + (Reply/Share x 25)
- 80–100: VIP — Community invite, early access to content
- 50–79: Core — Standard newsletter + monthly special content
- 20–49: Casual — Key summary version, short format
- 0–19: Dormant — Re-engagement sequence → if no response, clean from listA — Attribute (Attribute-Based)
| Attribute | Classification Criteria | Content Differentiation |
|---|---|---|
| Role | Developer / Marketer / Executive / Designer | Adjust examples and terminology level |
| Experience Level | Beginner / Intermediate / Expert | Include/exclude foundational explanations |
| Interest Topic | Click history by tag/category | Topic-specific curation |
| Signup Source | Blog / Social / Referral / Event | Onboarding matched to initial expectations |
R — Recency-Frequency
| Segment | R (Last Open) | F (Open Frequency) | Strategy |
|---|---|---|---|
| Champion | Within 7 days | Opens every issue | Exclusive content, referral program |
| Loyal Reader | Within 14 days | 1 in 2+ | Standard content, feedback requests |
| At-Risk | 14–30 days ago | Declining trend | "Did you miss this?" reminder |
| Dormant | 30+ days | Near zero | Final re-engagement → remove if no response |
Segment-Specific Content Strategy
Welcome Series (New Subscribers Only)
| Day | Purpose | |
|---|---|---|
| D+0 | Welcome + self-introduction + expectation setting | First impression, frequency/tone overview |
| D+2 | All-time top 3 content | Prove the newsletter's value |
| D+5 | "We'd love to know about you" — short survey | Collect segmentation data |
| D+10 | Exclusive content or resource | Incentivize long-term subscription |
Show full SKILL.md (199 more words)Show less
Re-engagement Sequence (At-Risk Readers)
| Step | Subject Line Pattern | Strategy |
|---|---|---|
| 1st | "We know you've been busy — just read this one" | Deliver one compressed top piece |
| 2nd | "Did we end up in your spam folder?" | Request whitelisting + technical fix |
| 3rd | "Here's an honest case for staying subscribed" | Reaffirm value, offer frequency options |
| No response | Remove from list | Maintain list health (protect deliverability) |
Send Time Optimization Matrix
| Subscriber Type | Best Day | Best Time | Rationale |
|---|---|---|---|
| B2B Professionals | Tue–Thu | 8–10 AM | Post-arrival email check window |
| Developers/Tech | Tue, Thu | 7–8 AM | Early-start habit |
| B2C General | Sat, Sun | 10 AM–12 PM | Weekend leisure time |
| Executives/Decision-makers | Tue, Wed | 6–7 AM | Pre-day check |
| Global Mixed | Tue | 2:00 PM UTC | Optimal cross-timezone intersection |
Content Personalization Levels
| Level | Method | Complexity | Effect |
|---|---|---|---|
| L1 | Name insertion (Hi [Name]) | Low | Open rate +10–15% |
| L2 | Reorder sections by interest topic | Medium | Click rate +20–30% |
| L3 | Completely different content versions per segment | High | Click rate +40–60% |
| L4 | Individual AI-powered recommendation curation | Very High | Click rate +50–80% |
Newsletter Health Metrics
| Metric | Healthy | Caution | Danger |
|---|---|---|---|
| Open Rate | 40%+ | 25–39% | Below 25% |
| Click-through Rate | 5%+ | 2–4% | Below 2% |
| Unsubscribe Rate | Below 0.3% | 0.3–0.5% | 0.5%+ |
| Spam Complaint Rate | Below 0.01% | 0.01–0.05% | 0.05%+ |
| List Growth Rate | 5%+/month | 1–4% | Below 0% |
