Package repeated AI-skill authoring with a scaffold workflow and repo-derived skills

[Copilot]

This issue asked for repository-based identification of repeated manual workflows, then creation of only high-confidence missing automation. The main recurring gap was cross-harness AI skill creation being repeated across recent issues/PRs without a shared, repo-native scaffold.

• Workflow shortlist and packaging decisions

  • Added AI_WORKFLOW_SHORTLIST.md with a compact, evidence-based shortlist:
    • repeated workflow
    • repo evidence
    • frequency/confidence
    • recommended form
    • create/skip rationale
  • Explicitly limits creation to high-confidence items and documents deliberate skips.
  • Updated the shortlist to record the additional repository-derived skills created from repeated chapter patterns.

• New automation: cross-harness AI skill scaffold script

  • Added New-AISkillScaffold.ps1 to generate a synchronized starter skill across:
    • .github/skills/<skill>/SKILL.md
    • .agents/skills/<skill>/SKILL.md
    • .claude/commands/<skill>.md
  • Enforces stable inputs (SkillName pattern + required Description) and deterministic outputs (fixed target paths/template structure).
  • Supports safe overwrite via -Force.

• Added repository-derived AI skills in all supported harness layouts

  • Added focused, repo-aware skills under .github/skills, .agents/skills, and .claude/commands for:
    • tiny-ps-chapter-test-loop
    • tiny-ps-deterministic-random
    • tiny-ps-regex-text-transform
    • tiny-ps-input-normalization
  • These encode repeated workflows evidenced across the chapter structure, tests, and READMEs rather than speculative new processes.

• Why this is narrow and repo-aware

  • Extends the repo’s existing PowerShell-first workflow style.
  • Avoids speculative CI/release automation where evidence was low.
  • Packages only repeated workflows that appear across multiple chapters or recent repository activity.

pwsh -NoProfile -File ./New-AISkillScaffold.ps1 `
  -SkillName tiny-ps-example `
  -Description "Use when implementing a repeatable Tiny PowerShell Projects workflow."

this is great. also. add a set of skills that you deem worthy

Added four repository-derived skills in all three harness layouts: chapter test loop, deterministic random, regex text transform, and input normalization. Addressed in ae16f4b.
