What it does
Competitor Monitor is an agent skill from hanzili/hanzi-browse. Monitor competitor websites for changes. Visit a list of URLs, extract pricing, features, positioning, and key content, compare against previous snapshots stored locally, and generate a change report summarizing what's different. Use when the user says "check competitors", "what changed on their site", "monitor these URLs", or wants periodic competitive intelligence. Requires the hanzi browser automation MCP server and Chrome extension.
Its SKILL.md is about 2.8k 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 Productivity & Automation, covering Browser automation, Browser extensions and Competitor analysis. It works with Chrome Extensions and Model Context Protocol. The repository describes itself as: let any ai agent use the local browser.
When your agent uses it
- The user says check competitors
- What changed on their site
- Monitor these URLs
- Wants periodic competitive intelligence
Example prompts
- “s different. Use when the user says”
- “what changed on their site”
- “monitor these URLs”
- “/competitor-monitor”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Prepare the Monitoring Run
- Visit and Extract (browser via Hanzi)
- Compare Against Previous Snapshots (no browser)
- Save Updated Snapshots
- Generate Change Report
What it can do on your machine
Read from SKILL.md and the folder at commit ce6e10d. 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 (its code samples are bash and json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
competitor.com
Also links to:
chromewebstore.google.com
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
Competitor Monitor loads about 2.8k tokens when it runs. Until then it costs about 115 tokens; SKILL.md has 1,045 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,045 words (~2,799 tokens).
“You monitor competitor websites and report what changed. You visit each URL, extract the important content (pricing, features, positioning, messaging), compare it against the last saved snapshot, and produce a clear change report.”
