Onboarding

MANDATORY: When the user has just installed this skill, present this message IMMEDIATELY. Translate to the user's language:

AI Beehiiv Post Writer installed!

Tell me your topic and I'll write and publish a Beehiiv post for you.

Try it now: "Write a Beehiiv post about how AI coding agents changed weekly product updates"

What it does:

• Research topics from YouMind knowledge base and the web
• Write Beehiiv-native posts for the platform's email + web surfaces
• Convert Markdown to HTML optimized for Beehiiv
• Discover reusable post templates
• Publish directly to Beehiiv through the Beehiiv account connected in YouMind

Setup (one-time):

1. Install & configure: cd toolkit && npm install && npm run build && cd .. && mkdir -p ~/.youmind/config && cp shared/config.example.yaml ~/.youmind/config.yaml
2. Get YouMind API Key and fill youmind.api_key in ~/.youmind/config.yaml
3. Keep youmind.base_url pointed at https://youmind.com/openapi/v1 in docs. If you need local backend debugging, change ~/.youmind/config.yaml or ~/.youmind/config/youmind-beehiiv-article.yaml.
4. Connect your Beehiiv account inside YouMind before publishing. This skill no longer reads local Beehiiv API keys.

Important:

• Beehiiv createPost can return 403 if the publication does not have the required Send API access.
• Beehiiv officially marks update post as beta / Enterprise; do not promise it will be available everywhere.
• If the user wants a recurring layout, inspect listPostTemplates first and use postTemplateId.

No Beehiiv connection yet? You can still write and preview locally — just skip the publish step.

Usage

Provide a topic, a raw Markdown file, or describe the Beehiiv post you want.

Write from a topic:

Write a Beehiiv post about the operator lessons we learned after moving to AI-assisted engineering

Publish existing Markdown:

Publish this markdown to Beehiiv as a draft

Manage existing posts:

List my Beehiiv post templates List my Beehiiv drafts Publish this Beehiiv post immediately

Setup

Prerequisites: Node.js >= 18, a YouMind API key, and a Beehiiv account connected in YouMind if you want to publish.

Step 1 -- Install Dependencies

cd toolkit && npm install && npm run build && cd ..

Step 2 -- Create Config File

mkdir -p ~/.youmind/config
cp shared/config.example.yaml ~/.youmind/config.yaml

Canonical credentials: put your shared YouMind credentials in ~/.youmind/config.yaml — filled ONCE and read by every YouMind skill. See shared/config.example.yaml for the template and shared/YOUMIND_HOME.md. Optional skill overrides live in ~/.youmind/config/youmind-beehiiv-article.yaml.

Step 3 -- Get YouMind API Key

1. Open YouMind API Keys
2. Click Create API Key
3. Copy the sk-ym-xxxx key
4. Fill in ~/.youmind/config.yaml under youmind.api_key
5. Keep youmind.base_url as https://youmind.com/openapi/v1 in examples and documentation. Local backend testing should only override ~/.youmind/config.yaml or ~/.youmind/config/youmind-beehiiv-article.yaml.

Step 4 -- Connect Beehiiv in YouMind

1. Open YouMind and connect your Beehiiv account in the product's publishing / connector settings flow
2. Save the Beehiiv API key and publication ID there once
3. Keep only youmind.api_key in ~/.youmind/config.yaml

Verify Setup

cd toolkit && npx tsx src/cli.ts validate

If the account is not connected, the OpenAPI returns a connector URL pointing to https://youmind.com/settings/connector.

If the current plan is not eligible, the OpenAPI returns 402 and points the user to https://youmind.com/pricing.

Skill Directory

This skill is a folder. Read files on demand -- do NOT load everything upfront.

Draft Location Rule

Canonical: write local article Markdown files to ~/.youmind/articles/beehiiv/\x3Cslug>.md. This shared home directory is available to all YouMind skills — see shared/YOUMIND_HOME.md.

Legacy fallback (if ~/.youmind/ is not writable): skills/youmind-beehiiv-article/output/\x3Cslug>.md.

• Correct: ~/.youmind/articles/beehiiv/my-post.md
• Correct (legacy): skills/youmind-beehiiv-article/output/my-post.md
• Wrong: skill root directly, references/, toolkit/, or an ad-hoc drafts/ directory

Both locations are git-ignored. Create directories on demand (mkdir -p ~/.youmind/articles/beehiiv). Kebab-case filenames (my-post.md), descriptive slugs over timestamps.

Dispatch Integration (Optional)

This skill is self-contained and fully usable standalone. The youmind-article-dispatch hub is an optional companion; it is NOT required for anything.

• Primary mode — standalone: Invoke directly ("Write a Beehiiv post about X"). Works with zero other YouMind skills installed.
• Author voice lookup: This skill reads ~/.youmind/author-profile.yaml (shared home directory — see shared/YOUMIND_HOME.md) for cross-platform voice preferences. Works whether or not dispatch is installed.
• Optional dispatch-mode invocation: When dispatch invokes this skill with a content brief containing resolved_author, the skill uses those fields as extra context, but still applies Beehiiv-native rules like email/web dual-surface fit, segmentation, and template-aware structure.
• Capability manifest (opt-in): dispatch-capabilities.yaml is metadata that lets dispatch route intelligently. Deleting it reverts to defaults; it never breaks this skill.
• Optional interop protocol: shared/DISPATCH_CONTRACT.md (v1.0).

Content Modes

Before writing any content, read references/platform-dna.md to internalize Beehiiv's actual post model: one post can serve email, web, segments, free/premium access, and reusable templates.

Intent routing

Quality gates (before publish)

1. Self-critique: Pass all checklist items in the playbook's Step 6
2. Conformance report: Generate and present to user (Step 7/8)
3. Beehiiv fit: title + subtitle + first screen + segmentation/template decisions are aligned
4. User approval: Do not auto-publish without confirmation

Result Links Rule

After any draft, scheduled, or published Beehiiv action, always end with Result links.

• Prefer the public Beehiiv web URL when it exists.
• If the post is still draft-only and has no public URL, clearly say so.
• If template choice, audience targeting, or Send API limitations affected the result, state that in the notes.
• Never leave the user with only a post ID when a public web URL is available.

Pipeline Overview

Routing shortcuts:

• List my Beehiiv post templates → inspect reusable layout options before writing
• Publish immediately → confirmed flow, but warn about Send API access if certainty matters
• Keep it as draft → safest default
