What it does
Skill Improver is an agent skill from Gentleman-Programming/gentle-ai. Trigger: improve skills, audit skills, refactor skills, skill quality. Audit and upgrade existing LLM-first skills.
Its SKILL.md is about 770 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/skill-style-guide.md`).
It sits in Agent Workflows, covering Skill management and Refactoring. The repository describes itself as: Gentle-AI configures the AI coding agents you already use: Claude Code, Cursor, OpenCode, Codex, Pi, and more. Choose persistent memory, Organic-Driven Development, curated… The licence is Apache-2.0.

What it can do on your machine
Read from SKILL.md and the folder at commit 81d2225. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Skill Improver loads about 771 tokens when it runs, and up to ~1.6k if it reads all its reference files. Until then it costs about 33 tokens; SKILL.md has 362 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Activation Contract
Use this skill when asked to audit, refactor, normalize, or improve existing SKILL.md files. Use skill-creator instead when creating a brand-new skill from a reusable pattern.
Hard Rules
- Treat
docs/skill-style-guide.mdas the normative style contract when it exists. - For installed global skills, use
references/skill-style-guide.mdas the bundled local copy whendocs/skill-style-guide.mdis unavailable. - Treat
SKILL.mdas the source of truth; preserve author intent, critical rules, activation semantics, and output requirements. - Use
.atl/skill-registry.mdas an index of skill names, triggers, scopes, and exact paths; do not expect generated summaries. - Default to audit-only. Modify files only when the user explicitly asks to apply improvements.
- Never delete meaningful content silently; move long explanation, examples, templates, or schemas into local
references/orassets/. - Do not invent triggers, policies, or domain rules. Mark ambiguous cases for human review.
Decision Gates
| Situation | Action |
|---|---|
| Missing or invalid frontmatter | Fix name, quoted one-line description, license, and metadata |
| Skill reads like tutorial docs | Convert to runtime instructions and move background to references/ |
| Body exceeds budget | Preserve rules, move examples/background to supporting files |
| Branching logic hidden in prose | Convert to a compact decision table |
| Rules conflict or intent is unclear | Report the issue; do not rewrite that rule automatically |

Execution Steps
- Read
docs/skill-style-guide.md; if unavailable, readreferences/skill-style-guide.md; if neither exists, enforce the core LLM-first structure: frontmatter, Activation Contract, Hard Rules, Decision Gates, Execution Steps, Output Contract, References. - Read
.atl/skill-registry.md; use listed paths to select skills. If missing, scan known skill directories for*/SKILL.md. - For each selected skill, audit metadata, trigger clarity, section order, body budget, actionability, decision gates, output contract, and local references.
- Return an audit report grouped by skill with severity and exact proposed changes.
- In apply mode, edit only safe issues, preserve content, create supporting files when needed, then rerun or request
gentle-ai skill-registry refresh.
Output Contract
Return:
- Skills audited and paths used.
- Issues found, grouped by severity.
- Files changed, if apply mode was requested.
- Registry refresh recommendation when skill metadata or paths changed.
- Ambiguities that need human review.
