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 | $0.00134 | $0.02352 |
| Opus 5 | $0.00067 | $0.01176 |
| Sonnet 5 | $0.00027 | $0.00470 |
| Haiku 4.5 | $0.00013 | $0.00235 |
Grade A, and why
perfect-web-clone 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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 258 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Perfect Web Clone
Pixel-perfect cloning is this skill. The current agent is the harness runtime.
pwc is the deterministic hands and eyes: it captures, persists, builds,
renders, replays, and measures. It never calls another model. You understand
the evidence, author code, and choose targeted repairs.
A single natural-language request such as “复刻 https://example.com” authorizes the entire local reproduction workflow. Treat it as one user operation even though the harness performs many internal tool calls and repair iterations.
Do not ask for routine confirmation when the request contains a usable URL. Infer that a full-page clone is the default. Continue across phases without returning control merely to announce progress or request ordinary implementation choices. Ask only when a missing fact would materially change scope, when credentials or new authority are required, or when the user must resolve an external blocker.
Deployment is never implicit. Produce a local build and review URL by default; deploy only when the user explicitly asks.
Use one owning agent for the whole page so global visual context survives across sections. Do not delegate unless the user explicitly asks.
Non-negotiable execution contract
- Run capture, planning, authoring, build, verification, repair, and handoff as one continuous task.
- Inspect every
okorsuccessflag and its error evidence. Never invent a tool result. - Preserve immutable raw evidence separately from normalized evidence. Refuse to plan from an incomplete capture.
- Reproduce every planned top-level section and every independently required critical region. Do not stop after the viewport or after a visually dominant subset.
- Implement and replay every required common interaction: carousel, menu, tabs, accordion/details, and other contracts discovered during capture. A visually similar but inert control fails.
- Run gates in dependency order. A downstream score cannot override an upstream structural or behavioral failure.
- Repair the smallest owning component identified by evidence, rebuild, and re-run all affected gates.
- Never hide, waive silently, or average away a red gate. A missing critical region cannot be offset by aggregate visual similarity.
- End only in
ready_for_user_revieworfailed_with_residuals. Only the user can accept the result.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

perfect-web-clone is a skill published in the GitHub repository ericshang98/Perfect-Web-Clone (264 stars, last pushed 12d ago), licensed MIT. It adds 134 tokens to every session and 2,352 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
