Build skills that travel.
Describe the job in ordinary language, learn from strong examples, and leave with a portable SKILL.md your agent can use.

description: Turn merged work
into a clear customer updateStart with the job
Give SkillForge the repeated work and the result you want. The editor keeps file structure out of the way while you decide what good looks like.
Describe the repeated job
Write the task in your own words, including the audience, evidence, and result the agent should use.
Compare with an example
Open a strong skill beside the draft. Select a passage and explain what makes it useful.
Review, test, and download
Inspect each proposal, edit the document, then save or download an ordinary SKILL.md.
What SkillForge changes
SkillForge turns a prompt-to-file jump into a visible review. The workspace keeps your library, draft, reference, and decisions in one readable frame.
Create a release-notes skill that groups changes by product area.
Draft readyRelease notes
Turn merged work into a clear update for customers.
When to use
When a release needs a concrete, product-area summary.
Output format
Group changes by area and keep every note concrete.
The product frame represents the working library, build strip, target editor, protected reference, and status bar.
Choose your runtime
The portable file is the core. The host decides how it discovers skills, exposes invocation controls, and loads tools or supporting resources.
| Runtime | Path | What to expect |
|---|---|---|
| Claude Code | Native Agent Skills | Uses portable SKILL.md with documented project, personal, plugin, and synced locations. |
| OpenAI Codex | Native + plugins | Uses repository and personal skills, with plugin distribution for packages that need it. |
| Gemini CLI | Native Agent Skills | Uses host discovery, trust, and progressive disclosure guidance when installing a skill. |
| Grok | Native + adapter | Supports skills and documented Claude-compatible locations; extensions still need testing. |
| skills.sh | Distributor | Discovers and installs Git-hosted packages; inspect the repository before granting access. |
| v0 and Vercel | Application builder | Uses project instructions, MCP, integrations, or a skill-enabled agent in its terminal. |
| Meta Llama | Harness dependent | Your application must implement discovery and loading for the portable core. |
A portable core, host-specific edges
Keep the workflow understandable across hosts, then isolate the controls that only one runtime can interpret.
Portable fields
Name, description, instructions, references, scripts, assets, inputs, outputs, and completion checks can travel with the work.
Host edges
Invocation controls, permissions, dynamic context, UI metadata, hooks, and tools may differ or be ignored.
Progressive detail
Keep the common path in SKILL.md. Move long policies, schemas, and edge cases into references.
Test the boundary
Run should-trigger, should-not-trigger, and incomplete-input tasks before adding host extensions.
Safety stays visible
SkillForge keeps the evidence and proposed work separate so you can decide what belongs in the saved draft.
Examples stay read-only
Learn from their structure without turning a protected example into an edit target.
Supporting files stay evidence
Files can inform a review. SkillForge never executes supporting material.
Changes arrive as proposals
Read the before and after, then accept, edit, or leave each change alone.
Saves create recovery snapshots
Local saves detect conflicts and create a recovery snapshot before replacement.
Read next
Start with the format, then choose the host-specific behavior you need to test.
What is an agent skill?
A practical guide to reusable agent work, triggers, resources, and observable outcomes.
Read guideSKILL.md format
Write a focused routing layer and a decision path that an agent can follow and test.
Read guidePlatform compatibility
Compare discovery, invocation, distribution, and harness behavior across runtimes.
View referenceLearn from examples
Transfer a useful pattern without copying source identity or constraints.
Read guideTest a skill
Build an evaluation loop around triggers, evidence, boundaries, and result.

Open and save local skills with the Codex or Claude tool already installed.
View desktop notesQuestions about the workspace
What is an agent skill?
A reusable set of instructions and examples that helps an AI agent handle a particular kind of work consistently.
Do I need to know Markdown?
No. Describe the job and edit the result visually. SkillForge still saves a normal SKILL.md.
Is SkillForge free?
Yes. A free browser account includes a daily build allowance, and the desktop downloads are free.
Does it work with Codex and Claude?
The browser handles its connection. Desktop uses the Codex or Claude tool already installed and signed in.
What file do I get?
A portable SKILL.md file that can travel with the examples and notes you choose to keep.
What is different on desktop?
Desktop opens and saves local files. Windows is available now; the verified Mac build still awaits public signing.
