What it does
Skill Standardization is an agent skill from aiskillstore/marketplace. Standardize and validate SKILL.md files against the Agent Skills specification (agentskills.io). Use when creating new skills, auditing existing skills for spec compliance, converting legacy skill formats to standard structure, or improving descriptions for reliable triggering. Triggers on: "validate skill", "create SKILL.md", "standardize skill format", "check skill spec", "skill frontmatter", "improve skill description", "add evals to skill".
Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts (for example `evals/evals.json`, `scripts/validate_skill.sh` and `skill-report.json`). Compatibility notes: Designed for Claude Code and compatible agent clients with filesystem access
It sits in AI & LLM Engineering, covering LLM evaluation and Skill authoring. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- Creating new skills
- Auditing existing skills for spec compliance
- Converting legacy skill formats to standard structure
- Improving descriptions for reliable triggering
Example prompts
- “validate skill”
- “create SKILL.md”
- “standardize skill format”
- “/skill-standardization”
Requirements
- A Bash shell
- Compatibility (from SKILL.md): Designed for Claude Code and compatible agent clients with filesystem access
- Pre-approved tools (allowed-tools): Bash, Read, Write, Edit, Glob, Grep
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Validate an existing skill
- Write an effective description
- Create a new SKILL.md
- Convert legacy section headings
- Add evaluation test cases
What it can do on your machine
Read from SKILL.md and the folder at commit ad8daf7. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
BashReadWriteEditGlobGrep
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Shell), which the agent can run.
Shell commands in SKILL.md call:
bashuvx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
agentskills.io
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.
Compatibility
Designed for Claude Code and compatible agent clients with filesystem access
From compatibility in the SKILL.md frontmatter.
Context cost
Skill Standardization loads about 2.1k tokens when it runs. Until then it costs about 118 tokens; SKILL.md has 535 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Bash, Read, Write, Edit, Glob, Grep
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); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 535 words (~2,061 tokens).
