Replace the truncated marketplace description

The manifest description contains a truncated serialization of the YAML frontmatter rather than the intended sentence. Installed-plugin cards, search, details, and chat context consume this field directly, so users will see text beginning with --- name: Spendline ... and ending mid-color value. Replace it with the complete human-readable description from SKILL.md.

AGENTS.md reference: plugins/AGENTS.md:L10-L10

Align the portable skill name with the plugin ID

For direct Agent Skills consumption or od plugin export, this SKILL.md is the portable contract, but its name is uppercase and differs from both the folder and manifest ID (design-system-spendline-msqb1t49). The repository plugin spec requires these identifiers to match and use lowercase letters, numbers, and hyphens; consumers enforcing that contract can reject or misidentify the exported skill. Keep “Spendline” as the display title, but set this field to the stable plugin ID.

Thanks @ihoti2001 — shipping the full plugin package with source and provenance files is the right shape for a design-system submission.

Before the reviewer queue picks this up, could you expand the PR body with the missing Why / What users will see / Surface area / Validation sections? That makes it much easier to scope the addition.

I found two merge-safe metadata fixes in the new Spendline plugin: the sidecar description is truncated, and the portable skill name does not match the stable plugin identity. The design-system content and runtime checks otherwise look sound; the repository guard, full typecheck, plugin-runtime typecheck/tests, and local plugin validation all pass.

Fallback location — new Spendline plugin SKILL.md frontmatter, line 2: the portable Agent Skills frontmatter uses name: Spendline, while the folder and sidecar identity use a separate lowercase slug. The daemon skill registry uses this frontmatter name as the skill id, and consumers that enforce slug-safe Agent Skills names can reject or misidentify the exported skill. Keep Spendline as the display title in open-design.json, but set this field to the sidecar's stable lowercase plugin id so direct skill consumption and plugin export resolve the same identity.

The manifest description is a truncated serialization of the skill frontmatter rather than the complete human-readable summary. Plugin cards, search/details views, and chat context use this field, so users will see an incomplete description even though the source skill has the full sentence. Replace this value with the complete Spendline description (or generate it from the parsed frontmatter) and add a manifest-validation fixture that rejects truncated descriptions.

Hey @ihoti2001 — @nettee has the current actionable items covered on this head.

The two fixes to make next are:

• update the portable skill name in SKILL.md to the stable lowercase plugin id
• replace the truncated manifest description in open-design.json with the full human-readable summary

Once those are addressed, the next pass can focus on the updated head.
