create-skill

create-skill is a plugin for Claude Code from fledgeling-co/fledgeling-plugins. Its manifest loads nothing; the 1 skill it bundles cost 244 tokens per session together, scanned A, original, MIT.

A guided workflow for creating a new coding-agent skill from nothing. It clarifies the skill's purpose, researches its subject, tests the result, and prepares it for release.

In plain words
What is it for?
Use it when building a new skill, checking it against a no-skill baseline, preparing its visual branding, or adding it to an existing plugin.
Why use it?

Security

Grade A, and why

create-skill scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

{
  "name": "create-skill",
  "description": "Build a brand-new skill from scratch: a broad clarifying interview that pins down trigger, output and done condition before anything is written, paid+free deep research on the skill's domain (read in full, citations verified), the build itself run through skill-creator with every structural choice traced to evidence, proof against a no-skill baseline with structural evals and a blind multi-family judge panel, then the full brand treatment and ship. The sibling of improve-skill:improve-skill, for when there is no predecessor to improve. v1.3.0 hardens the brand phase, which is where this pipeline was quietly skippable: a bundled `render_banner.py` renders banner-src.html and asserts the five things that fail silently (viewport override took effect, web font actually loaded, every image decoded, nothing overflows the frame, PNG is exactly 3200x1040), the marketplace catalogue gate now fails on a missing banner, and the pipeline has answers for three cases it previously had none for: the user forbidding questions, an existing in-repo research corpus that makes a second panel redundant, and a skill that joins an existing plugin rather than getting one of its own.",

What it installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 244 tokens a session between them. Each is measured on its own page, and each can be installed alone.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
