────────────────────────────────────────────────────────────────────── SKILLS (agentskills.io/specification conformant, with legacy shim) ──────────────────────────────────────────────────────────────────────

On-disk layout (spec):

~/.pwn/skills/<name>/SKILL.md      ← required entrypoint, YAML frontmatter
~/.pwn/skills/<name>/scripts/      ← optional executables (was flat *.rb)
~/.pwn/skills/<name>/references/   ← optional supporting docs
~/.pwn/skills/<name>/assets/       ← optional binary assets

Legacy shim (read-only, still loaded so nothing breaks on upgrade):

~/.pwn/skills/<name>.{md,txt,rb,skill,yml,yaml}

Frontmatter (SKILL.md, --- YAML block at top of file):

name:         REQUIRED  [a-z0-9-]{1,64}, must equal parent dir name
description:  REQUIRED  1..1024 chars
license:      optional
metadata:     optional  Hash (pwn stores references here too)
allowed-tools: optional Array of toolset names

.load_skills(opts = {}) ⇒ Object

Supported Method Parameters

skills = PWN::Config.load_skills( pwn_skills_path: 'optional - Path to skills folder. Defaults to ~/.pwn/skills' )

Loads skills into the PWN::Skills constant. Two on-disk shapes are accepted so upgrades are seamless:

agentskills.io  →  <root>/<name>/SKILL.md      (preferred; written by write_skill)
legacy flat     →  <root>/<name>.{md,txt,rb,skill,yml,yaml}

Each entry: { type:, format:, path:, dir:, content:, description:, references:, frontmatter:, loaded:?, error:? }

.migrate_legacy_skills(opts = {}) ⇒ Object

Supported Method Parameters

report = PWN::Config.migrate_legacy_skills( pwn_skills_path: 'optional - override skills root', delete_legacy: 'optional - remove flat file after migration (default true)' )

One-shot converter: every flat ~/.pwn/skills/*.md (etc.) becomes a spec-conformant /SKILL.md with backfilled frontmatter. Idempotent.

1) frontmatter `references:` (legacy pwn)
2) frontmatter `metadata: { references: [...] }` (spec-conformant slot)
3) markdown `## References` bullet section
