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 | $0.00055 | $0.00641 |
| Opus 5.5 | $0.00022 | $0.00256 |
| Sonnet 5.5 | $0.00011 | $0.00128 |
| Haiku 4.5 | $0.00006 | $0.00064 |
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`, dynamic mirroring for a single page, How it starts
The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
What I do
- Capture websites into a local directory, rewriting links so they work offline.
- Provide three modes:
- static: fast mirroring with
wgetfor server‑rendered sites. - dynamic single‑page: renders a single page with Playwright to capture assets loaded after JavaScript execution.
- dynamic multi‑page: follows internal links within the same domain up to a specified depth, capturing multiple pages.
- static: fast mirroring with
- Produce one or more
index.htmlfiles (mirroring the site structure) and areport.jsonsummarizing downloaded files.
When to use me
Use this skill when you want Claude Code to create a mirror of a live site, for archiving or offline analysis. Choose static mode for simple, server‑rendered sites; dynamic single‑page mode for SPAs or JavaScript‑heavy pages; and dynamic multi‑page mode when you need to mirror multiple internal pages.
How to run
In the Claude Code environment, use the shell tool to run:
python3 mirror.py <URL> -o <output_dir>
for static sites, or
python3 mirror_dynamic.py <URL> -o <output_dir>
for dynamic single‑page sites.
If you need to mirror multiple pages on a dynamic site, run:
python3 mirror_dynamic_multi.py <URL> -o <output_dir> --depth <N> --concurrency 3 --max-pages 50
Replace <N> with a small integer (e.g., 1) to control how many link levels to follow. The optional
--concurrency flag sets how many pages are processed concurrently and --max-pages limits the total
number of pages captured. After the command completes, open the appropriate index.html files in the
preview browser. Review report.json for information about captured assets.
Installation
- Place the
claude-site-mirrordirectory into your Claude skills folder (~/.claude/skills/for global use or.claude/skills/in a specific project). - Ensure
mirror.pyandmirror_dynamic.pyare present in your project root or reachable via the shell environment. - Claude will detect the skill automatically when you start a new session.
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 55 tokens to every session and 641 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.
