Hey @dvdksn 👋

ran your skills through tessl skill review at work and found some targeted improvements for create-lab-guide. Here's the full before/after:

Skill Before After Change
create-lab-guide 69% 90% +21%

improves the create-lab-guide skill's description and content structure. The skill had the lowest baseline score (69%) across the repo's 11 skills, with the most room to grow, so it made sense to focus here.

Changes made
  • Rewrote frontmatter description with explicit "Use when..." clause and five natural trigger terms (create a lab guide, write a Labspace page, add a Docker lab tutorial, migrate a lab to docs, document a hands-on lab)
  • Fixed duplicate "Step 2" heading - renumbered to a proper 5-step sequence (Clone → Extract → Write → Style → Validate)
  • Added validation step (Step 5) with explicit gate: frontmatter field checks, prettier formatting, lint/vale pass, and manual review before commit
  • Compressed style rules from a verbose bullet list into a scannable two-column table
  • Replaced prose file listing with a structured table mapping files to their purpose
  • Preserved all Labspace domain expertise: labspace.yaml, labspace-launch shortcode, dockersamples org conventions, model-download parameter, compose.override.yaml model detection

I also stress-tested your write skill against a few real-world task evals and it held up really well on issue verdict decision trees with cross-referenced timeline checks. Kudos for that.

Honest disclosure. I work at @tesslio where we build tooling around skills like these. Not a pitch, just saw room for improvement and wanted to contribute.

If you want to self-improve your skills, or define your own scenarios to pressure test, just ask your agent (Claude Code, Codex, etc.) to evaluate and optimize your skill with Tessl. Ping me @yogesh-tessl, if you hit any snags.

## Description

Improves the `create-lab-guide` skill's description and content structure. The skill had the lowest baseline score (69%) across the repo's 11 skills, with the most room to grow — so it made sense to focus here.

<details>
<summary>Changes made</summary>

- **Rewrote frontmatter description** with explicit "Use when..." clause and five natural trigger terms (`create a lab guide`, `write a Labspace page`, `add a Docker lab tutorial`, `migrate a lab to docs`, `document a hands-on lab`)
- **Fixed duplicate "Step 2" heading** — renumbered to a proper 5-step sequence (Clone → Extract → Write → Style → Validate)
- **Added validation step (Step 5)** with explicit gate: frontmatter field checks, prettier formatting, lint/vale pass, and manual review before commit
- **Compressed style rules** from a verbose bullet list into a scannable two-column table

I also stress-tested your `triage-issue` skill against a few real-world task evals and it held up really well on issue verdict decision trees with cross-referenced timeline checks. Kudos for that.
