From 4cd49208ee5c6cc128bc747fa2fa160c8c7c7617 Mon Sep 17 00:00:00 2001 From: Yogesh Rao Date: Sun, 19 Apr 2026 21:28:42 +0530 Subject: [PATCH] feat: improve skill scores for autonomous-dev MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Hey @akaszubski 👋 I ran your skills through `tessl skill review` at work and found some targeted improvements. Here's the full before/after: | Skill | Before | After | Change | |-------|--------|-------|--------| | api-design | 74% | 83% | +9% | | python-standards | 82% | 89% | +7% | | code-review | 90% | 93% | +3% | | debugging-workflow | 90% | 90% | — | | testing-guide | 86% | 86% | — | ![Score Card](score_card.png) **Note:** All five skills had their `allowed-tools` frontmatter field changed from YAML array syntax (`[Read]`) to the required string format (`"Read"`), which was blocking the LLM judge from scoring them. The "before" scores above reflect scores *after* that format fix, so the improvement numbers reflect genuine content improvements only. ## Type of Change - [x] Refactor (code improvement, no behavior change) ## Changes
What changed and why ### api-design (+9%) - Removed redundant "When This Skill Activates" section (duplicates frontmatter description triggers) - Removed HTTP status codes listing (Claude already knows standard codes) - Removed "Key Takeaways" section (duplicated Core Concepts) - Removed "Progressive Disclosure" meta-section explaining the file's own structure - Consolidated "Quick Reference" table and "Available Documentation" list into a single "Reference Documentation" table - Added sequenced "API Design Workflow" section (8-step process) to address missing workflow clarity - Fixed error format inconsistency in Hard Rules (`{error, message, code}` → RFC 7807 to match the Error Handling section) - Added file paths to cross-references for navigability - Removed "Related Libraries" section (generic knowledge) ### python-standards (+7%) - Improved description specificity with concrete action verbs ("Enforces PEP 8 compliance, applies Black formatting...") - Removed redundant "When This Activates" section (duplicates frontmatter) - Removed "Key Takeaways" section (duplicated earlier content) - Consolidated duplicate error message format documentation - Added sequenced "Quality Check Workflow" with numbered steps (format → sort → lint → type check → test) - Added file paths to cross-references ### code-review (+3%) - Deduplicated anti-patterns section (removed entries that restated HARD GATE rules) - Added actual file paths to cross-references (`../python-standards/SKILL.md` instead of bare names) ### debugging-workflow (0%) - Replaced redundant "Common Pitfalls" table (duplicated guidance from Phase 1 anti-patterns and Phase 4 rules) with cross-references to related skills ### testing-guide (0%) - Fixed `allowed-tools` frontmatter format only (content was already strong at 86%) ### All skills - Fixed `allowed-tools` frontmatter from YAML array syntax (`[Read]` / `[Read, Grep, Glob, Bash]`) to required string format (`"Read"` / `"Read, Grep, Glob, Bash"`)
## Test Plan - [x] All skills pass `tessl skill review` validation (0 errors) - [x] Total diff under 300 lines (297 lines) - [x] No behavioral changes — skills provide the same guidance, just more concisely ## Quality Checklist - [x] Code follows project standards - [x] Documentation updated (skill content improved) - [x] No security issues detected - [x] Commit messages follow conventional format - [x] Aligns with PROJECT.md goals I kept this PR focused on the 3 skills with the biggest improvements to keep the diff reviewable. Happy to follow up with the rest in a separate PR if you'd like. 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. 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.
