  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by jonathimer on GitHub. Read the source before you install it.

Installation

Install the Developer Lead Gen AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/jonathimer/devmarketing-skills.git /tmp/devmarketing-skills
mkdir -p .claude/skills
cp -r /tmp/devmarketing-skills/skills/developer-lead-gen .claude/skills/developer-lead-gen
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Developer Lead Gen in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Developer Lead Gen on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Developer Lead Gen is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Developer Lead Generation

Overview

Traditional lead generation tactics fail with developers. Gating content behind forms generates resentment, not qualified leads. Developers have finely-tuned spam detectors and share warnings about pushy tools in their communities.

Effective developer lead gen focuses on providing genuine value upfront—free tools, useful utilities, and ungated resources that solve real problems. Conversion happens when developers recognize the value and choose to engage, not when they're forced through a funnel.

Why Traditional Lead Gen Fails with Developers

What Developers Reject

Form-gated content:

  • PDFs that could be blog posts
  • "Ebooks" that are product pitches
  • Whitepapers with no original research
  • Webinar recordings hidden behind forms

Aggressive tactics:

  • Chatbots that appear immediately
  • Exit-intent popups
  • Required email for documentation
  • Forced account creation for trials

Fake value:

  • "Free" tools that require signup to use
  • Calculators that email results
  • Generic content disguised as resources

Why It Fails

  1. Developers talk: One bad experience gets shared in Slack channels, Twitter, and Hacker News
  2. Temporary emails: Developers use disposable addresses for forms
  3. Ad blockers: Many developers block tracking and popups
  4. Time protection: Developers guard their attention fiercely
  5. Trust loss: Pushy tactics damage brand perception permanently

Building Free Tools That Generate Leads

Tool Ideas That Attract Developers

Effective developer tools solve specific, frequent problems:

Format converters:

  • JSON to YAML (and vice versa)
  • Timestamp converters
  • Base64 encode/decode
  • Markdown to HTML

Generators:

  • UUID generators
  • Password/secret generators
  • Regex builders and testers
  • Cron expression builders
  • .gitignore generators

Validators/linters:

  • JSON validators
  • YAML validators
  • SQL formatters
  • Code formatters

Calculators:

  • Unix timestamp calculators
  • Color converters (hex to RGB)
  • Byte size converters
  • Rate limit calculators

Reference tools:

  • Cheat sheets (keyboard shortcuts, syntax)
  • Status code references
  • Comparison tables

Characteristics of Successful Tools

Instantly useful:

  • No signup required to use
  • Works immediately on visit
  • Solves problem in seconds

Actually good:

  • Better than existing alternatives
  • Fast and reliable
  • Clean, developer-friendly interface

Shareable:

  • Unique URLs for results
  • Easy to bookmark
  • Worth recommending to others

Connected to your product:

  • Related to problems your product solves
  • Natural bridge to main offering
  • Demonstrates your understanding of developers

Build vs Buy Decisions

Build when:

  • Tool is core to your product positioning
  • No good alternatives exist
  • You can make it meaningfully better
  • Team has bandwidth for maintenance

Buy/use existing when:

  • Tool is commodity (another JSON formatter)
  • Maintenance burden isn't worth it
  • You're early stage and need to focus
  • Existing tools can be embedded or whitelabeled

Considerations:

  • SEO value (builds over time with owned tools)
  • Brand association (own tools = your brand)
  • Maintenance cost (bugs, updates, hosting)
  • Development time vs other priorities

Ungated vs Gated Strategy

What to Never Gate

  • Documentation
  • API references
  • Getting started guides
  • Error message explanations
  • Basic tutorials
  • Open source projects

What Can Be Gated (Carefully)

If you must gate something, ensure value clearly exceeds effort:

Potentially acceptable:

  • Extended, high-production courses
  • Original research reports with real data
  • Tools that require infrastructure (CI/CD, etc.)
  • Personalized assessments

Gating guidelines:

  • Value must be obvious before the gate
  • Email-only, no long forms
  • Clear privacy policy
  • Instant access after submission
  • Easy unsubscribe

The "Soft Gate" Approach

Instead of hard gates, use soft engagement:

Optional signup benefits:

  • Save progress/results
  • Sync across devices
  • Access history
  • Additional features

Example:

"This regex tester works without an account. Sign up to save your expressions and access them anywhere."

This respects developer autonomy while providing genuine upgrade value.

Conversion Without Forms

Behavioral Signals Over Form Fills

Track meaningful engagement:

High-intent signals:

  • Multiple tool uses
  • Sharing tool URLs
  • Returning visitors
  • Documentation deep reads
  • GitHub star

Medium-intent signals:

  • Newsletter signup (when ungated content is excellent)
  • Community join (Discord, Slack)
  • Following social accounts
  • Bookmarking pages

Building Trust-Based Conversion Paths

Instead of form -> nurture -> sales, consider:

Value-first path:

  1. Developer finds free tool
  2. Tool solves their problem
  3. Developer explores who made this
  4. Discovers your main product
  5. Evaluates on their own terms
  6. Signs up when ready

Community path:

  1. Developer joins community for peer help
  2. Sees your team being helpful
  3. Trusts your expertise
  4. Considers your product when need arises
  5. Self-selects into trial

In-Product Conversion Points

For free tools, natural conversion points:

Capability limits:

  • "Export as PDF available in [Product]"
  • "API access for automation in paid plans"
  • "Bulk processing available in Pro"

Adjacent problems:

  • "Like this? [Product] solves the bigger problem"
  • "This tool is part of [Product Suite]"
  • "Built by the team behind [Product]"

Measuring Attribution

The Attribution Challenge

Developer journeys are non-linear:

  • Long consideration periods
  • Multiple touchpoints
  • Dark social (Slack, DMs, calls)
  • Ad blockers break tracking

What You Can Measure

First-touch indicators:

  • "How did you hear about us?" (open field, not dropdown)
  • Referrer data (with limitations)
  • UTM parameters for campaigns
  • Direct traffic spikes after events/content

Engagement depth:

  • Pages viewed before signup
  • Tools used before signup
  • Content consumed
  • Time to conversion

Proxy metrics:

  • Search volume for brand terms
  • Direct traffic trends
  • Community mentions
  • GitHub stars correlation with signups

Self-Reported Attribution

Ask new users how they found you—but do it right:

Good approach:

  • Open text field
  • Asked during onboarding (not blocking)
  • Simple question: "How did you hear about us?"
  • Optional to answer

Avoid:

  • Dropdown menus (miss real answers)
  • Required fields
  • Leading options
  • Asking too late

Building Attribution Models

Accept imperfect data and use multiple signals:

Multi-touch view:

  • First touch: How they discovered you
  • Influenced touches: What built trust
  • Last touch: What triggered signup

Cohort analysis:

  • Compare conversion rates by entry point
  • Track lifetime value by acquisition channel
  • Identify highest-quality sources

Budget and ROI Considerations

Free Tool Investment

Development costs:

  • Simple tools: 1-5 developer days
  • Complex tools: 2-4 weeks
  • Ongoing maintenance: 10-20% of build time annually

Infrastructure:

  • Hosting: $50-500/month depending on traffic
  • CDN: Often included or minimal
  • Analytics: Free to $100/month

ROI calculation:

  • Traffic value: What would this cost via ads?
  • Brand value: Hard to quantify but real
  • SEO value: Long-term compounding
  • Lead value: Signups attributed to tool

Content Investment

Ungated content:

  • Higher volume needed (no scarcity)
  • SEO compounds over time
  • Builds trust before lead capture
  • Lower conversion rate, higher quality leads

Break-even thinking:

  • If this content generates X signups at Y conversion rate at Z lifetime value, does it pay for itself?
  • Include long-term SEO value
  • Factor in brand building

Tools

  • Plausible/Fathom: Privacy-respecting analytics (developers don't block as often)
  • PostHog: Product analytics for engagement tracking
  • Segment: Event tracking across touchpoints
  • Attribution tools: Various options, all imperfect
  • Octolens: Find where developers discuss problems your tools could solve, identifying content and tool opportunities

Common Mistakes

  1. Gating too early: Requiring signup before demonstrating value
  2. Fake ungated: "Free tool" that requires signup
  3. Over-engineering: Building complex tools when simple ones suffice
  4. No connection: Free tools with no bridge to main product
  5. Ignoring maintenance: Tools that break lose trust
  6. Over-attributing: Trusting imperfect data too much
  7. Under-attributing: Ignoring what you can learn from limited data

Why use Developer Lead Gen on TypingMind?

Because you install it once and use it with any model. Developer Lead Gen is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Developer Lead Gen in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/jonathimer/devmarketing-skills/tree/main/skills/developer-lead-gen. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Developer Lead Gen?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Developer Lead Gen?

As many as you like. As long as a model supports skills, you can use Developer Lead Gen with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Developer Lead Gen AI skill free?

Yes. It is published on GitHub by jonathimer under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
