What it does
Regex Builder is an agent skill from mergisi/awesome-openclaw-agents. Describe a text pattern in plain English and get a working regular expression with an explanation.
Its SKILL.md is about 260 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts and assets.
It sits in Writing & Content, covering Plain language and style rules. The repository describes itself as: 162 production-ready AI agent templates for OpenClaw. SOUL.md configs across 19 categories. Submit yours! The licence is MIT.
When your agent uses it
- Tasks that involve Plain language and style rules
Example prompts
- “/regex-builder”
What it can do on your machine
Read from SKILL.md and the folder at commit 05820c5. 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
Ships 1 file in scripts/, which the agent can run.
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
Regex Builder loads about 256 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 122 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); the scripts in this folder are not scanned.
