Agent Skill Creator

Turn any workflow into reusable AI agent software that installs on 17 platforms — no spec writing, no prompt engineering, no coding required.

How it fits together: your description runs through the 5-phase creator pipeline, the generated skill must pass every quality gate before install, and the shipped evolve loop keeps it green after you stop looking. Watch a real quality-gate run.

What you get: describe a workflow in plain English (or hand over a PDF, a link, a script) → a complete, validated and security-scanned agent skill, with functional code, its own eval spec, and a cross-platform installer → the same skill running on Claude Code, Cursor, Copilot, Gemini, Windsurf, and 12 more with one command.

Quick start

# macOS / Linux — paste into Terminal
curl -fsSL https://raw.githubusercontent.com/FrancyJGLisboa/agent-skill-creator/main/scripts/bootstrap.sh | sh

Then open your AI tool and describe what you do:

/agent-skill-creator Every Friday I clean the CRM export, calculate regional
totals, and email a PDF sales report.

…and watch it build the skill end to end:

▸ Phase 1  Discovery     ▸ Phase 4  Detection
▸ Phase 2  Design+evals   ▸ Phase 5  Build · validate · security-scan
▸ Phase 3  Architecture

✓ weekly-crm-report-skill  (23 files: evals, installer, plugin manifests, evolve loop)
  installed on Claude Code, Cursor, Gemini CLI

Use it:  /weekly-crm-report-skill data/crm-export.csv
  → report.pdf   → dashboard.html

No clone, no pip, no API key to get started — just git and any one of 17 supported tools. Windows one-liners and single-tool installs are in the Installation Guide.

Why this vs. the alternatives

	Agent Skill Creator	Hand-writing a SKILL.md	Anthropic's skill-creator
Time to a working skill	~minutes, one prompt	hours of spec + iteration	minutes (interactive Q&A)
Coding required	none — it writes the code	yes	some
Cross-platform install	17 platforms, auto-detected + format adapters	one tool, by hand	Claude-focused
Built-in validation + security scan	yes (hard gates)	manual	partial
Ships an eval spec (regression metric)	yes, per skill	no	no
Optimizable (autoresearch handoff)	yes	no	no
Input you can hand it	prose, PDF, URL, code, transcript	you write it from scratch	guided prompts

Anthropic's skill-creator is excellent for authoring a Claude skill interactively. This is for turning whatever you already have into a validated skill that installs everywhere, with the testing and security gates wired in.

Examples

Three runnable example skills ship in references/examples/. Each one passes the same gates the creator applies to your skills — validate.py, check_pipeline.py, and its own bundled eval spec (run_evals.py --rollout):
