Install authoritative meta-skills for skill creation and discovery

[Copilot]

The repo needed canonical meta-skills for building and navigating skills rather than relying on fragmented guidance scattered across repositories. I installed the most authoritative, widely used patterns as actual agent skills under .github/skills so they are discoverable and usable as first-class capabilities.

• Scope

  • Add the canonical "create a skill" workflow used by Anthropic’s official skill ecosystem.
  • Add the canonical "find the right skill" workflow used by the VRIL skill-jam pattern for discovery and sequencing.
  • Keep the manifest metadata compact and agent-friendly so the skills trigger correctly without overbroad instructions.

• Changes

  • skill-creator

    • Added a meta-skill that covers intent capture, workflow-to-skill conversion, drafting SKILL.md, testing/prompts, eval iteration, and trigger optimization.
    • Encodes the production pattern: define the job, write the manifest, evaluate against real prompts, and refine until output and execution are reliable.
    • Keeps the guidance explicit about boundaries, progressive disclosure, and outputs so the skill remains useful and scoped.

  • skill-navigator

    • Added a meta-skill for deciding whether a skill is needed, narrowing candidate skills by trigger conditions, and sequencing them by task phase.
    • Emphasizes the right selection criteria: task structure, domain fit, output contract, token efficiency, and invocation timing.
    • Provides a consistent output format for recommending the best skill or chain without forcing a skill on tasks that are better handled inline.

  • Packaging

    • Installed both as actual skills in .github/skills/skill-creator/SKILL.md and .github/skills/skill-navigator/SKILL.md.
    • Included structured YAML frontmatter and concise descriptions to make them discoverable by agent skill runtimes.

• Example

---
name: skill-creator
description: >
  Create new agent skills, improve existing ones, and evaluate their performance with test cases.
  Use when a user wants to turn a workflow into a reusable skill, refine a SKILL.md, optimize
  triggering and output contracts, or benchmark a skill against a baseline.

Pull request overview

This PR adds two meta-skills under .github/skills/ intended to provide canonical workflows for skill creation and skill discovery/selection, so agents can invoke these as first-class capabilities.

Changes:

• Added a new skill-creator meta-skill documenting a workflow for drafting, testing, and iterating on skills.
• Added a new skill-navigator meta-skill documenting a workflow for choosing and sequencing skills, with an output format and examples.
