web-access

web-access is a skill for Codex from Ce-Legend/ce-legend-skills. It costs 173 tokens per session (1,160 once invoked), scanned A, original, MIT.

A skill that gives Codex instructions for reaching information and services outside the coding workspace. It covers searching, opening pages, checking current facts, using interactive websites, and handling logged-in browser sessions.

In plain words
What is it for?
Use it to research current information, inspect or download web content, operate websites, verify actions, and preserve where information came from.
Why use it?
It helps choose an appropriate way to access external information and verify that the result was actually obtained.

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-access scanned grade A with 1 finding 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 10d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/cdp-proxy.mjs, scripts/check-deps.sh, scripts/match-site.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Web Access

Use this skill as Codex's external-world access layer. It closes the gap between model memory and live reality: current facts change, pages render through JavaScript, important evidence hides behind interaction, and some workflows only exist inside a logged-in browser session.

Treat web work as an evidence pipeline. Define the needed result, choose the lightest credible access layer, preserve source trails, escalate only when the page demands it, and stop when the requested outcome is verified.

What This Skill Protects Against

  • stale answers from model memory when the facts may have changed
  • weak research based on search snippets instead of opened sources
  • losing source provenance, publication dates, timestamps, or page state
  • overusing browser automation when a direct source read is enough
  • underusing browser automation when content is rendered, interactive, or login-bound
  • treating a clicked button, upload, download, or form submission as successful before verifying the resulting state

Core Workflow

  1. Define the success condition. Decide whether the task needs a current fact, a primary-source answer, a completed web action, a downloaded artifact, a screenshot, or browser state verification.

  2. Start with the lightest reliable layer. Use search and direct page reads for factual lookup. Use browser automation only when content is dynamic, interactive, gated by UI state, or depends on upload/download flows.

  3. Escalate by evidence. If a page is incomplete, blocked, login-sensitive, JavaScript-rendered, or behaving differently from raw HTML, move to a browser layer instead of repeating the same failed fetch.

  4. Return verifiable output. For research, cite sources and prefer primary material. For browser actions, report the exact completed state and any remaining uncertainty.

Tool Selection

Prefer this order unless the user request clearly starts at a higher layer:

  • Built-in web/search tools: current facts, source discovery, page reading, finance/weather/sports lookups, and citation-backed answers.
  • Playwright or in-app browser tools: clicking, typing, DOM inspection, screenshots, uploads, downloads, and JavaScript-heavy pages.
  • Direct HTTP tools such as curl: status codes, headers, meta tags, raw HTML, JSON, JSON-LD, robots, sitemap, and minimal page probes.
  • Local Chrome CDP fallback: tasks requiring the user's Chrome login state, regular browser profile behavior, or pages that fail in isolated browser contexts.

Changes

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.

web-access is a skill published in the GitHub repository Ce-Legend/ce-legend-skills (54 stars, last pushed yesterday), licensed MIT. It adds 173 tokens to every session and 1,160 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
