Hey @machaval 👋

great work. 28 skills covering the full Anypoint Platform lifecycle, from API discovery and portal curation to MCP server security and agent scanning. The split between platform operations skills and Mule development skills shows a clear understanding of the two audiences using this repo. Really thorough work.

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

Skill Before After Change
jtbd-generator 77% 93% +16%
Changes made

Description improvements:

  • Expanded frontmatter description with additional concrete actions (validate, update) beyond just generate
  • Added capability details: "discovers matching API operations", "maps cross-step data flow", "produces validated hybrid-format files"
  • Converted description from block scalar (|) to quoted string format for better portability

Content improvements (biggest impact):

  • Removed redundant intro paragraph and "How to Use" preamble that duplicated the frontmatter description
  • Extracted verbose Example Interaction, Error Handling, Tips for Quality Output, and Success Criteria sections - these explained concepts Claude already understands and bloated the file from 510 to 273 lines
  • Consolidated the 5 data flow detection rules into a compact "Data Flow Rules" section inline with the workflow
  • Replaced the 40-line Python utility API reference with a concise "References" section pointing to lib/ module docstrings and the existing README.md
  • Line count dropped from 510 → 273, clearing the validation warning about file length

also stress-tested your jtbd-generator skill against a few real-world task evals - the 6-step Parse → Discover → Analyze → Generate → Validate → Save workflow held up really well on multi-operation API deployments with cross-step data flow mapping. Kudos for that.

quick honest disclosure. I work at https://github.com/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.

Hey @machaval 👋

I ran your skills through `tessl skill review` at work and found some targeted improvements for `jtbd-generator`. Here's the before/after:

| Skill | Before | After | Change |
|-------|--------|-------|--------|
| jtbd-generator | 77% | 93% | +16% |

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

**Description improvements:**
- Expanded frontmatter description with additional concrete actions (`validate`, `update`) beyond just `generate`
- Added capability details: "discovers matching API operations", "maps cross-step data flow", "produces validated hybrid-format files"
- Converted description from block scalar (`|`) to quoted string format for better portability

**Content improvements (biggest impact):**
- Removed redundant intro paragraph and "How to Use" preamble that duplicated the frontmatter description
- Extracted verbose Example Interaction, Error Handling, Tips for Quality Output, and Success Criteria sections — these explained concepts Claude already understands and bloated the file from 510 to 273 lines
- Consolidated the 5 data flow detection rules into a compact "Data Flow Rules" section inline with the workflow
- Replaced the 40-line Python utility API reference with a concise "References" section pointing to `lib/` module docstrings and the existing `README.md`
- Line count dropped from 510 → 273, clearing the validation warning about file length

**Unchanged skills:**
- All other 27 skills left untouched

I also stress-tested your `jtbd-generator` skill against a few real-world task evals — the 6-step Parse → Discover → Analyze → Generate → Validate → Save workflow held up really well on multi-operation API deployments with cross-step data flow mapping. Kudos for that.

Want to self-improve your skills? Just point your agent (Claude Code, Codex, etc.) at [this Tessl guide](https://docs.tessl.io/evaluate/optimize-a-skill-using-best-practices) and ask it to optimize your skill. Ping me — [@yogesh-tessl](https://github.com/yogesh-tessl) — if you hit any snags.

Thanks in advance 🙏

hey @machaval, just a gentle nudge in case this got buried, let me know if you need any changes!
No rush at all if this is in a review pipeline.
