A conversion tool for turning a local HTML file into screenshots, a vector PDF, an MP4 video, or a GIF. HTML is the file format commonly used to structure web pages.

Use it to export local web pages as images, documents, video, or animation while checking that the captured page contains content.

It provides one route for producing several media formats and checks for page errors or blank captures instead of silently exporting a bad result.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00050	$0.05332
Opus 5.5	$0.00020	$0.02133
Sonnet 5.5	$0.00010	$0.01066
Haiku 4.5	$0.00005	$0.00533

Security

Grade B, and why

html-export scanned grade B 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 3d ago.

The scan reads SKILL.md. This mod also ships 18 executable files (scripts/export.cjs, scripts/lib/browser.cjs, scripts/lib/exit-codes.cjs, …), 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

How it starts

The opening of the file, as written. The whole thing — 202 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Codex compatibility note:

Invoke $skill-name: load the registered .agents/skills/<name>/SKILL.md and execute it with Codex tools; no separate Skill tool or Claude mode switch is needed. Author .claude/**; mirrors are generated.

Track steps before execution and keep progress/evidence current. Explicit skill requests execute their protocol. Use the native question tool for required questions.

Map foreign tool names to available host capabilities. A name mismatch needs no approval; an actually unavailable required capability stops with its step/evidence and a user question before adaptation.

Subagent authorization: when a skill is user-invoked or AI-detected and its protocol requires subagents, that skill activation authorizes use of the required spawn_agent subagent(s) for that task.

Preserve protocol order unless the user approves a deviation. Workflows use $start-workflow: gates stay fixed; other steps may flex with logged reasons and evidence.

Quick Summary

Goal: Turn a local HTML file into PNG screenshots with a page-error and blank-capture check, a vector PDF, an MP4 or a GIF, through one entry point that reports the result as an exit code.

Workflow:

Pick a target — --to=png (render evidence), --to=pdf (print or slides), --to=mp4 / --to=gif (deterministic animation recording)
Check setup — dependencies are opt-in and skill-local; a missing one exits 3 with the setup commands
Export — node .claude/skills/html-export/scripts/export.cjs --to=<target> <input...> [options]
Read the exit code first — then report.json / frames.json, then the output; a written file is never proof on its own. A reused --out keeps earlier outputs: only the files this run's manifest names belong to it — report.json files[] (png), report.json output (pdf), frames.json output (mp4/gif)

Key Rules:

--to is required; there is no default target.
Nothing is ever installed on the user's behalf. Exit 3 means NOT VERIFIABLE plus a setup pointer.
Render only HTML the project or the user produced; anything fetched or untrusted only with --offline (see Trust).
The HTML stays canonical. Fix the page or pick the right selector; never restructure HTML for the exporter.

Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

What ships with it

26 files 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.

html-export is a skill published in the GitHub repository duc01226/EasyPlatform (12 stars, last pushed yesterday), licensed MIT. It adds 50 tokens to every session and 5,332 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-18.
