Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.00616 |
| Opus 5.5 | $0.00021 | $0.00246 |
| Sonnet 5.5 | $0.00011 | $0.00123 |
| Haiku 4.5 | $0.00005 | $0.00062 |
Grade A, and why
site-mirror 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 2mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
Supports static mirroring via `wget` and dynamic mirroring via Playwright to What it actually says
What I do
- Download websites for offline browsing. Captures HTML, CSS, JS, images, fonts and media.
- Offer two modes: static using
wgetand dynamic using Playwright. - Produce an
index.htmlwith rewritten links and areport.jsonsummarizing assets.
When to use me
Invoke this skill when you need a local mirror of a site. Use static mode for simple sites, dynamic single‑page mode for modern SPAs, or dynamic multi‑page mode when you need to follow internal links.
How to run
In a Codex session, use the shell tool to run one of the following:
python3 mirror.py <URL> -o <output_dir>
for static sites, or
python3 mirror_dynamic.py <URL> -o <output_dir>
for dynamic single‑page sites. Replace <URL> with the target site and <output_dir>
with a folder name. After completion, open <output_dir>/index.html to browse.
If you need to follow internal links on a dynamic site (e.g., capturing several pages from the same domain), use the multi‑page crawler:
python3 mirror_dynamic_multi.py <URL> -o <output_dir> --depth 1 --concurrency 3 --max-pages 50
The --depth option controls how many link levels to follow. The optional
--concurrency sets how many pages to process in parallel (default: 3) and
--max-pages limits the total number of pages captured (default: unlimited). Use these
options to tune performance and avoid downloading an entire site unintentionally.
Installation
To install this skill locally:
- Copy the directory
codex-site-mirrorto your global skills folder (~/.agents/skills/) or project folder (.agents/skills/). - Ensure the
mirror.pyandmirror_dynamic.pyscripts are accessible in your project or on your PATH. - Codex will automatically load the skill the next time you start a session.
Alternatively, package this skill as a plugin and install it via codex's
skill installer.
Notes
- Respect copyrights and robots.txt. Do not mirror sites without permission.
- Install Playwright (
pip install playwright && playwright install) for dynamic mode.
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.

site-mirror is a skill published in the GitHub repository ajmaluk/site-mirror-skill (2 stars, last pushed 4mo ago), licensed MIT. It adds 53 tokens to every session and 616 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
