ak-plan: bundled skill is missing agent-creation.md

[gelleson]

Summary

The installed ak-plan skill requires leaders to read
references/agent-creation.md before creating workers, but that file is not
included in the skill package.

Command

cat ~/.agents/skills/ak-plan/references/agent-creation.md

Expected

The referenced worker-creation instructions are available.

Actual

No such file or directory

The installed references/ directory contains only:

• leader-verification.md
• runtime-delegation.md
• specialist-profiles.md
• wait-monitoring.md

Context

• ak version: 1.13.4
• OS: macOS
• Runtime: Codex
• Auth type: agent

Reproduction

1. Invoke the installed ak-plan skill.
2. Reach Phase 3 / worker creation.
3. Follow the instruction in runtime-delegation.md to read
   references/agent-creation.md.

Proposed Skill Change

Either bundle references/agent-creation.md with the skill or replace its
references with the complete worker-creation rules already present in
runtime-delegation.md.
