# /blog-writer

Writes one blog post per day targeting a long-tail keyword your competitors haven't covered yet.

## Skills to Load

- `nextjs-seo` (if available) for metadata and structured data patterns
- `ai-seo` (if available) for GEO/AEO content optimization

## MCP Servers Used

- `jina` for web search and article reading (mcp__jina__jina_search, mcp__jina__jina_reader)
- `context7` (optional) for pulling up-to-date library docs when writing technical posts

## Pre-flight

1. Read `docs/project/product-overview.md` to understand the product, audience, and positioning.
2. Read `docs/project/brand-guidelines.md` for voice, tone, and vocabulary rules.
3. Scan existing posts to avoid duplicate keywords:
   ```bash
   grep -r "^title:" content/blog/ --include="*.mdx" | sort
   ```
4. Read the last 3 published posts to match voice and sentence cadence.

## Phase 1: Topic Research

Use Jina search to find what's trending in your niche today:

```
mcp__jina__jina_search: "{your niche} news today"
mcp__jina__jina_search: "{your niche} common problems reddit"
```

Pick a topic that:
- Has a long-tail keyword (3-5 words, 500-2,000 monthly searches)
- No existing post covers it (check the grep output from pre-flight)
- Maps to a real problem your product solves, even indirectly
- Works as a "how to" or "what is" query (these index fastest)

## Phase 2: Research the Topic

Read 3-5 top sources on the topic using Jina reader:

```
mcp__jina__jina_reader: "https://example.com/article-about-topic"
```

Extract concrete facts, numbers, code patterns, and common mistakes. Never invent data points.

## Phase 3: Write the Post

Output path: `content/blog/{category}/{slug}.mdx`

Frontmatter:

```yaml
---
title: "Keyword-Front-Loaded Title"
description: "One sentence. ~120 chars. Zero 4-word overlap with opening paragraph."
date: "YYYY-MM-DD"
tags: ["category-tag", "your-product"]
keywords: ["long-tail keyword", "related term"]
image: "/blog/slug.png"
readingTime: "N min read"
published: true
---
```

Post skeleton:

- Opening: 2-4 punchy sentences. State what the reader gets. Lead with outcome.
- Problem section: 2-3 sentences. Concrete pain the reader has felt.
- Quick Win: One code block or config snippet that works immediately.
- 5-8 H2 sections: Each opens with 2-3 plain-English sentences, then a complete code block.
- Takeaway: 2-3 sentences. Reframes the opener. Never "in conclusion."

## Phase 4: GEO Optimization

Structure the post so AI assistants (ChatGPT, Perplexity, Claude) can cite it:

- Open sections with clear one-sentence definitions ("X is Y that does Z.")
- Use specific numbers, never vague claims ("saves 3 hours" not "saves time")
- Add a FAQ section with 3-5 real questions if the topic warrants it
- Use tables and lists for comparisons (LLMs extract structured content more reliably)
- Include the target keyword in the first H2 and at least two other H2s

## Phase 5: Verify

```bash
cd webapp && npx tsc --noEmit
```

Must pass clean. Check that description and first paragraph share zero 4-word phrases.

## Writing Rules

- Short paragraphs: 1-3 sentences. 65% should be 1-2 sentences.
- Zero em-dashes. Use periods, commas, or colons.
- Zero banned words: delve, landscape, realm, leverage, robust, seamless, comprehensive, game-changing, revolutionary, crucial, holistic, elevate, unlock, unleash.
- Lead with outcome, not process. "You" in 50% of paragraphs. Zero "I".
- Colon before every code block. Every code block complete and self-contained.
- Every sentence readable by a non-developer.

## Error Recovery

- tsc fails: fix type errors in frontmatter or MDX syntax, re-run.
- Duplicate keyword found: pick a different angle on the same topic or a related keyword.
- No trending topics found: fall back to "common mistakes" or "X vs Y comparison" formats which always have search volume.

# /posthog-analyst

Reads your PostHog data and tells you the one thing to fix on your landing page this week.

## MCP Servers Used

- `posthog` (required) for all analytics queries (mcp__posthog__query-run, mcp__posthog__insights-get-all, mcp__posthog__insight-query, mcp__posthog__projects-get)

## Pre-flight

1. Verify PostHog MCP is connected:
   ```
   Call mcp__posthog__projects-get
   ```
   If it fails: stop and report "PostHog MCP not connected. Run `npx @posthog/wizard mcp add` and restart Claude Code."

2. Read `docs/project/product-overview.md` for product context (what matters to track).
3. Read `docs/built/analytics.md` (if it exists) for the event taxonomy and funnel definitions.

## Phase 1: Discover Events

If no event map exists yet, auto-discover what's being tracked:

```
Call mcp__posthog__event-definitions-list to see all custom events.
Call mcp__posthog__properties-list to see available properties.
```

Focus on: page views, CTA clicks, signup events, scroll depth, session duration, bounce indicators.

## Phase 2: Pull This Week's Data

Use PostHog MCP query tools to pull the last 7 days:

```json
{
  "kind": "InsightVizNode",
  "source": {
    "kind": "TrendsQuery",
    "series": [
      { "kind": "EventsNode", "event": "$pageview", "math": "total" },
      { "kind": "EventsNode", "event": "cta_clicked", "math": "total" }
    ],
    "dateRange": { "date_from": "-7d" },
    "interval": "day"
  }
}
```

Pull these metrics:
1. Page views by URL (breakdown by $current_url)
2. CTA click rate (cta_clicked / $pageview on the landing page)
3. Scroll depth distribution (if scroll_depth_reached events exist)
4. Bounce rate (single-page sessions / total sessions via HogQL)
5. Session duration (median and p75 via HogQL: `median(session_duration)`)
6. Signup funnel conversion (if signup events exist)

Then pull the SAME queries for the previous 7 days (date_from: -14d, date_to: -7d) for comparison.

## Phase 3: Analyze and Compare

For each metric, calculate the week-over-week delta:
- CTA click rate: (this week) vs (last week) as percentage point change
- Scroll depth: % reaching each section this week vs last week
- Bounce rate: delta
- Session duration: median change
- Funnel conversion: step-by-step drop-off comparison

Rank regressions by impact. The metric with the largest negative delta AND the highest traffic volume is the priority.

## Phase 4: Write Recommendation

Find the single biggest regression or opportunity. Write one specific paragraph:

1. Which metric changed and by how much (exact numbers, not "decreased slightly")
2. Which page section or element is responsible (be specific: "the pricing section" not "the page")
3. What to change (concrete: "Move the primary CTA above the pricing table. Add a second CTA after the feature grid." not "improve the CTA placement")
4. Expected impact based on the data delta

## Phase 5: Optionally Apply the Fix

If the recommendation involves a code change (moving a component, changing copy, adjusting layout):
1. Find the relevant file in `app/(marketing)/page.tsx` or the component it imports
2. Make the change
3. Run `npx tsc --noEmit` to verify
4. Report what was changed

If the fix requires design review or A/B testing, skip this phase and just report the recommendation.

## Output

Write to `docs/analytics/weekly-{YYYY-MM-DD}.md`:

```markdown
## PostHog Weekly: {date}

### Key Metrics (vs previous week)
| Metric | This Week | Last Week | Delta |
|--------|-----------|-----------|-------|
| Page views | {n} | {n} | {+/-n%} |
| CTA click rate | {n%} | {n%} | {+/-pp} |
| Bounce rate | {n%} | {n%} | {+/-pp} |
| Median session | {n}s | {n}s | {+/-n%} |
| Signup conversion | {n%} | {n%} | {+/-pp} |

### Top Regression
{one paragraph}

### Recommendation
{one paragraph with the specific change}

### Applied
{YES with file path, or NO with reason}
```

## Rules

- Never guess. Only recommend changes backed by a measurable delta.
- One recommendation per run. The most impactful one.
- If all metrics are stable or improving, say "all metrics stable" and stop.
- A 44% scroll depth is only bad if it dropped from a higher number. Context matters.
- Never track PII beyond email/name. Never log passwords, tokens, or credit card data.

## Error Recovery

- PostHog MCP call fails: check project ID, try `mcp__posthog__switch-project` if multiple projects exist.
- No events found: report "No custom events tracked yet. Run /analytics first to set up event tracking."
- Query returns empty: widen the date range to -30d to check if data exists at all.

# /carousel-maker

Turns blog posts into Instagram carousels. One post in, seven slides out.

## Pre-flight

1. Find the latest blog post without a carousel:
   ```bash
   # List all blog posts
   ls -t content/blog/**/*.mdx | head -10
   # List existing carousels
   ls output/carousels/
   ```
   Match by slug. Pick the most recent unmatched post.

2. Read the blog post fully. Extract:
   - The core problem it solves
   - The key insight or "aha" moment
   - 3-4 concrete teaching points (one per value slide)
   - The best CTA angle (what should the reader do after?)

3. Read the last 2 shipped carousels under `output/carousels/` for design patterns and component usage. Study, don't copy.

4. Read `src/components/index.ts` to see what's available to import.

## Carousel Structure

7 slides. Each 1080x1350 (4:5 aspect ratio for Instagram feed).

- **Slide 1 (Hook)**: One headline that stops the scroll. Max 8 words in the big line. Must include a bespoke visual (chart, icon grid, mockup). Never a plain text slide.
- **Slides 2-6 (Value)**: Each teaches one point. Max 25 words per slide. Each slide uses a visual element to support the text.
- **Slide 7 (CTA)**: Comment keyword in large gradient text. "Follow @YOUR_HANDLE for more." Logo + domain.

## Design System

Define your brand tokens at the top of the file. Consistency matters more than novelty:

```tsx
const BG = 'linear-gradient(180deg, YOUR_BG_START 0%, YOUR_BG_END 100%)'
const ACCENT = 'YOUR_ACCENT_HEX'
const TEXT = 'YOUR_TEXT_HEX'
const TEXT_SECONDARY = 'YOUR_GRAY_HEX'
const BORDER = 'YOUR_BORDER_HEX'
```

## Layout Rules

- Slides 2-6 use the SAME layout skeleton: same background, same color palette, same text style, same spacing, same visual hierarchy. Consistency across all value slides.
- Only the hook (slide 1) and CTA (slide 7) break the pattern.
- All custom visuals are inline components in the same TSX file. Never modify shared component files.
- Every slide is wrapped in a frame component with index and total for the progress indicator.

## Content Rules

- No jargon. Write for someone who has never coded. If a technical term is needed, explain it in the same sentence.
- Max 25 words per slide body (excluding code snippets).
- No price on slides. Price goes in the Instagram caption.
- No glow effects, drop shadows, or radial halos.
- No colored left-border accents on cards.
- Content must not overlap the footer/brand bar area.

## Render and Verify

```bash
npx tsx scripts/render-tsx.ts output/carousels/{YYYY-MM-DD}-{slug}/carousel.tsx
```

After rendering, open EVERY PNG and check:
1. Text is readable at phone screen size
2. No content overlaps the footer
3. No dead space (80px+ empty areas)
4. Hook slide headline reads in under 3 seconds
5. A non-technical person would understand each slide

If any check fails, fix and re-render.

## Output

```
output/carousels/{YYYY-MM-DD}-{slug}/carousel.tsx
output/carousels/{YYYY-MM-DD}-{slug}/slide-01.png through slide-07.png
```

## Error Recovery

- Render fails: check TSX syntax, verify all imports exist in `src/components/index.ts`.
- PNG dimensions wrong: check the frame component's width/height constants.
- Text overflows: reduce word count or font size. Never let text clip.

# /reddit-scout

Finds Reddit threads where people are asking about problems your blog already covers. Drafts replies. You review and post.

## MCP Servers Used

- `jina` (optional) for reading linked articles in threads via mcp__jina__jina_reader

## Pre-flight

1. Read your blog post index to know what topics you can actually help with:
   ```bash
   grep -r "^title:\|^description:" content/blog/ --include="*.mdx" | head -30
   ```
2. Read `docs/project/product-overview.md` to understand the product (so you can avoid accidentally shilling it).

## Phase 1: Scrape

Hit Reddit's public JSON endpoints. No API key needed:

```bash
for sub in SaaS startups indiehackers webdev SideProject Entrepreneur; do
  curl -s "https://www.reddit.com/r/$sub/hot.json?limit=30" \
    -H "User-Agent: scout/1.0" > "/tmp/reddit-$sub.json"
done
```

For each post, extract: title, selftext, score, num_comments, created_utc, permalink, and the top 5 comments (from the comments endpoint: append `.json` to the permalink).

## Phase 2: Score

Rate each thread on three axes (5 points each, max 15):

**Recency**
- Last 6 hours: 5
- Last 24 hours: 4
- Last 48 hours: 3
- Last 7 days: 1
- Older: 0

**Relevance**
- Topic directly matches a published blog post title or keyword: 5
- Topic is adjacent (same category, different angle): 3
- Tangentially related: 1
- No match: 0

**Opportunity**
- Question with zero good answers: 5
- Top answer is incomplete, outdated, or wrong: 4
- Active discussion where your angle is missing: 3
- Well-answered already: 0

Keep threads scoring 10+. Discard the rest.

## Phase 3: Draft Replies

For each qualifying thread:

1. Read the person's actual question. The body text, not just the title.
2. Read the existing top comments. Never repeat what someone already said.
3. Find the matching blog post. Read it to pull concrete advice.
4. Draft a reply.

Each reply must:
- Give a concrete answer: steps, a code snippet, a config change, specific tool names
- Stay under 200 words
- Never mention your product, company, or domain name
- Never include a link
- End with an open door like "happy to go deeper on any of this"

Match the subreddit voice:
- r/webdev: technical. Show code. Cite docs.
- r/SaaS: business outcomes. Revenue numbers. Conversion rates.
- r/startups: lessons from experience. Be honest about what didn't work.
- r/Entrepreneur: ROI. Time saved. Cost comparisons.
- r/SideProject: build log energy. What stack, how long, what's next.
- r/indiehackers: transparent. Share real numbers. Admit limitations.

## Voice

Write like a real person on Reddit. Not a brand. Not an AI.

Drop "I" and "We" most of the time. Instead of "I built this" write "built this last week." Instead of "I think you should" write "you probably want to." Keep it sharp and funny when the moment is right but don't force it.

Don't over-punctuate. Don't write nicely formatted sentences with perfect grammar. Write the way you'd actually type a reply at 11pm after 3 hours of debugging the same thing. Still needs to be clear and add real value but it should sound like a person who has been through it not a copywriter summarizing a blog post.

Good voice:
- "honestly tried like 5 different approaches before landing on this one and it just works"
- "same thing happened to me except the webhook kept timing out on top of everything else lol"
- "yeah so basically you want to set up the cron first then worry about the handler logic after"

Bad voice (sounds AI):
- "Great question! Here's what I'd recommend based on my experience..."
- "I completely agree with this perspective. Additionally, you might want to consider..."
- "This is a common challenge. The solution involves three key steps."

## Output

Write to `output/reddit-drafts/{YYYY-MM-DD}.md`:

```markdown
## Thread: {title}
**Sub**: r/{sub} | **Score**: {n} | **Comments**: {n} | **Age**: {hours}h
**URL**: https://reddit.com{permalink}
**Matching post**: {blog post title}
**Opportunity score**: {n}/15

### Draft reply

{the reply text}

---
```

## Rules

- 90/10 rule. 9 out of 10 replies are pure value with zero product mention. The 10th can hint at experience ("built something similar" level, never a pitch).
- Zero emoji. Zero hashtags. Reddit culture is anti-both.
- Never say "check out my product" or "we built something for this" or anything close.
- If a thread is a support question for a specific competing tool, skip it.
- Read existing top comments before drafting. If someone already gave the same advice, skip or add a different angle.
- The agent drafts. You review, edit in your voice, and post manually.

## Error Recovery

- Reddit JSON returns 429 (rate limited): wait 60 seconds and retry. If persistent, reduce to 3 subreddits per run.
- Zero qualifying threads: lower the score threshold to 8 or try `--sort rising` instead of `hot`.
- Blog post index is empty: report "No blog posts to match against. Run blog-writer first."
