web-task-agent

web-task-agent is a skill for Claude Code, Codex from matteotitta/genesys-skills. It costs 206 tokens per session (2,224 once invoked), scanned A, original, MIT.

A browser-based workflow for carrying out multi-step web tasks in two modes: monitoring a page for changes or checking a website for links, buttons, and structured data.

In plain words
What is it for?
Use it to watch pages for changes, test website calls to action and links, and check whether structured data matches expectations.
Why use it?
It provides a repeatable way to inspect websites and report findings instead of relying on one-off browser actions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

web-task-agent scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/web-task-agent — plain-language web task → multi-step loop

Run a web task as a multi-step browser loop on MCPs you already pay for. No new runtime, no API double-billing, no new always-on MCP. Two v1 modes: monitor (watch a page, report a grounded diff) and QA (walk a site, check CTAs/links/schema, flag mismatches).

Provenance

Adapted from browser-use (github.com/browser-use/browser-use, MIT, © 2024 Gregor Zunic) per /steal analysis (2026-06-08) — see .claude/discovery/0626-browser-use-steal-analysis.md. We lift the loop discipline (pre-done verification, soft loop nudges, action chaining, ground-every-claim) as prompt patterns. We do not import the library — the loop runs on Chrome DevTools + Firecrawl MCPs already mounted. That call is the verdict's central KILL: the library duplicates our stack and adds a second Chromium + paid LLM keys.

What this is / is not

A thin orchestration skill: it wraps existing MCPs with a disciplined loop. Client-agnostic — invoke for any engagement or Genesys-internal motion.

Use this when Use something else when
Watch a page and report what changed Build/clone a site → /website-build, /website-clone
Walk a site checking CTAs / links / schema One-shot scrape of one URL → Firecrawl directly
A repeatable multi-step web task on existing MCPs LinkedIn engager/profile/job scraping → Apify skills
Open-web research → Exa per exa-protocol.md
Form-filling / login-walled automation → deferred to v2

Triggers

Invoke when the user says:

  • /web-task <url> <what to do>
  • "monitor this page for changes" / "watch this competitor page"
  • "QA the CTAs on this site" / "check every link on [url]"
  • "check what changed on [url] since last time"

Do NOT invoke when:

  • The job is building or cloning a site (/website-build, /website-clone)
  • A single firecrawl_scrape answers the question (no loop needed)
  • The data lives behind a login or needs form submission (v2 — refuse for now, name the reason)
  • A pre-built Apify actor already covers the source (LinkedIn, job boards)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
