[bug] Packaged RDLC SKILL.md files fail YAML parsing

[BaseInfinity]

Summary

Fresh Codex startup reports that two packaged rdlc skills from codex-rdlc-wizard are skipped because their SKILL.md front matter is invalid YAML.

Visible output

From a Codex v0.137.0 startup in /Users/stefanayala/naz365:

Skipped loading 2 skill(s) due to invalid SKILL.md files.

/Users/stefanayala/.codex/skills/codex-rdlc-wizard/skills/rdlc/SKILL.md: invalid YAML: mapping values are not allowed in this context at line 2 column 60

/Users/stefanayala/.codex/skills/codex-rdlc-wizard/plugins/codex-rdlc-wizard/skills/rdlc/SKILL.md: invalid YAML: mapping values are not allowed in this context at line 2 column 60

Expected behavior

The bundled rdlc skill should load cleanly after installing or enabling codex-rdlc-wizard.

Suspected cause

Both affected files have an unquoted YAML front-matter description with a colon in the scalar value, for example:

description: Full RDLC workflow for Codex research projects: evidence gathering, confidence labels, audience-firewalled deliverables, fact regressions, slop scan, and review.

Quoting the description or using a block scalar should make the front matter parseable.

Repro notes

• Wizard version seen in installed bundle: 0.1.0
• Codex version in screenshot: v0.137.0
• Trigger: start a fresh Codex session after the wizard skill bundle is installed
• A screenshot exists, but the error text above captures the actionable failure.

Additional dogfooding confirmation from the VisualHUD Codex session:

• Codex startup still surfaced the RDLC packaged-skill YAML parse warning.
• The visible path was:

/Users/stefanayala/.codex/skills/codex-rdlc-wizard/plugins/codex-rdlc-wizard/skills/rdlc/SKILL.md: invalid YAML: mapping values are not allowed in this context at line 2 column 60

• The local installed package metadata seen during investigation was codex-rdlc-wizard 0.1.0.
• A duplicate issue with the narrower path-specific report exists at RDLC bundled skill fails YAML frontmatter parse due unquoted colon #3; this issue has the fuller packaged-skill scope and should probably remain canonical.

Suggested acceptance coverage: validate every packaged SKILL.md frontmatter file under both skills/ and plugins/**/skills/ before release, using the same parser strictness Codex applies at startup.

Still reproduces on 2026-06-20 in a fresh Codex session from /Users/stefanayala/naz365.

Visible startup output:

Skipped loading 2 skill(s) due to invalid SKILL.md files.

/Users/stefanayala/.codex/skills/codex-rdlc-wizard/skills/rdlc/SKILL.md: invalid YAML: mapping values are not allowed in this context at line 2 column 60

/Users/stefanayala/.codex/skills/codex-rdlc-wizard/plugins/codex-rdlc-wizard/skills/rdlc/SKILL.md: invalid YAML: mapping values are not allowed in this context at line 2 column 60

Local file check confirms both affected SKILL.md files still use the unquoted frontmatter line:

description: Full RDLC workflow for Codex research projects: evidence gathering, confidence labels, audience-firewalled deliverables, fact regressions, slop scan, and review.

The colon after projects is the likely parser break. The fix should quote that scalar in both packaged skill copies and add a package validation test that parses every emitted SKILL.md frontmatter before publish/install.
