Start with the Codex output

OpenAI describes Codex CLI as a coding agent that runs locally and can read, change, and run code in the selected directory. The open source Codex repository describes the same basic shape: a local coding agent that works on your computer.

That makes Codex a natural place to generate HTML work products:

• a migration review report
• a design comparison page
• a test or CI summary
• a small prototype for a feature discussion
• an implementation handoff packet

The problem is what happens after the file exists. A local report.html is useful to the person running Codex. It is less useful to a reviewer, manager, customer, or teammate who needs a stable link.

That is where the publish step belongs. Codex creates the artifact. BinHTML hosts the artifact as a managed, sandboxed link.

If you are still deciding where generated HTML should live, start with the complete guide to publishing AI-generated HTML.

Decide whether it is an artifact or a website

Do not publish every generated HTML file the same way.

Use a full deployment platform when Codex has created a maintained website or app that needs a repository, custom domain, build pipeline, server routes, environment variables, analytics, or production ownership.

Use a BinHTML artifact link when the output is a generated work product:

• one complete HTML document
• direct review or handoff
• no custom domain needed
• source should remain inspectable
• the link may be updated, revoked, grouped, or allowed to expire

That distinction keeps the workflow small. A Codex-generated report usually should not become a production deploy just because someone needs to open it in a browser.

For the broader decision, see Share AI-generated HTML and Host AI-generated websites.

Publish with the API when the file is already known

Use the BinHTML API when the publishing step is deterministic. This is the right fit when Codex has already written the HTML file and your script or CI job knows exactly what to upload.

A typical flow looks like this:

1. Ask Codex to create or update reports/review.html.
2. Run your test or review command.
3. Upload the complete HTML document to POST /api/v1/artifacts.
4. Return the BinHTML shareUrl in the pull request, issue, or handoff note.

That keeps the network action outside the model's judgment. Codex prepares the file; your automation performs the upload with a known API key, title, project name, visibility, and expiry policy.

API publishing is also easier to audit. The request has a clear payload, the response has a stable shape, and failures can be retried by the same system that owns the run.

Publish with MCP when Codex is doing the handoff

Use BinHTML MCP publishing when the agent is still assembling the handoff and should return the final link as part of the conversation.

MCP is designed so servers can expose tools that models can discover and invoke. The MCP tools specification also emphasizes human-visible tool invocation, confirmation for operations, input validation, rate limits, and audit logging. That matters for publishing because creating a share link is an external action, not just text generation.

A good MCP-shaped Codex instruction is specific:

1. Build the HTML review packet from this branch.
2. Publish it to BinHTML as an unlisted artifact in the Release review project.
3. Return the share link, source link, and a short reviewer note.

That gives Codex a clean job: generate the artifact, call the publishing tool, and hand back a URL instead of pasting raw HTML into chat.

If the output has several related documents, use the project publishing path instead of returning a pile of artifact links. For example, a launch handoff might include a summary, risk register, and appendix. One project link is easier for reviewers to open and pass around.

Keep the source and review path clear

Generated HTML should stay inspectable. Reviewers should know what they are opening, who owns it, and whether it is the current version.

Before publishing, ask Codex to check these basics:

• the HTML is complete and self-contained enough for the reviewer
• the title explains the review job
• the artifact does not include secrets, tokens, or customer data that should not be shared
• links point to intended destinations
• the page does not pretend to be a first-party product surface
• the handoff note says what changed and what the reviewer should check

BinHTML handles the artifact side of the workflow: sandboxed rendering, share URLs, source access, versions, visibility, expiry, and project grouping. Codex should handle the content side: make the artifact accurate, scoped, and reviewable.

For safety checks before sending a link, use Run a Link Preflight Before Sharing Generated HTML.

A simple Codex handoff prompt

Use this as a starting point:

If you do not want Codex to call a tool, split the job:

1. Ask Codex to generate the HTML file locally.
2. Inspect it yourself.
3. Publish it with the BinHTML API or dashboard.

The important part is the boundary. Codex is good at producing the review artifact. BinHTML is the share layer that turns that artifact into a managed link.
