clone-agent and detect-mode skills fail to load: argument-hint must be a string

[Dewain27]

Bug

Two skills fail to load with the error argument-hint must be a string:

• skills/clone-agent/skill.md
• skills/detect-mode/skill.md

Error

When running /skills in the CLI, the following is shown:

The following skills failed to load:
X ...skills\clone-agent\SKILL.md: argument-hint must be a string
X ...skills\detect-mode\SKILL.md: argument-hint must be a string

Root Cause

Both skill frontmatter files use unquoted square brackets for argument-hint, which YAML parses as an array rather than a string:

# clone-agent/skill.md
argument-hint: [agent name or environment hint]

# detect-mode/skill.md
argument-hint: [--agent-dir <path>]

YAML interprets [...] without quotes as an inline sequence (array), but the CLI requires argument-hint to be a string.

Fix

Wrap the values in quotes:

# clone-agent/skill.md
argument-hint: "[agent name or environment hint]"

# detect-mode/skill.md
argument-hint: "[--agent-dir <path>]"

Impact

Skills still load and function correctly once their argument-hint is quoted ? this is purely a YAML parsing issue in the frontmatter.
