What it does
Kuri Agent is an agent skill from justrach/kuri. Use kuri-agent to automate Chrome — navigate pages, interact with elements via a11y refs, capture screenshots, run security audits, enumerate cookies/JWTs, probe for IDOR vulnerabilities, and make authenticated fetches. Use when the user wants to automate a browser, test a web app, scrape data, or run security trajectories against a live site.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Security, covering Authentication, Security review and Web application vulnerabilities. The repository describes itself as: Browser automation, web crawling, and iOS + Android device control for AI agents. Zig-native, token-efficient CDP snapshots, HAR recording, native adb wire-protocol client, and a…
When your agent uses it
- The user wants to automate a browser
- Run security trajectories against a live site
Example prompts
- “/kuri-agent”
Requirements
- Pre-approved tools (allowed-tools): Bash
What it can do on your machine
Read from SKILL.md and the folder at commit 8c4f5b9. 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:
Bash
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
jq
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
Kuri Agent loads about 1.3k tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 171 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
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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 171 words (~1,303 tokens).
“kuri-agent drives Chrome via CDP. It stores session state in ~/.kuri/session.json so commands chain together naturally.”
