Build and review realtime and near-realtime htmx features. An agent skill from hashgraph-online/awesome-codex-plugins.

  • Job status updates

What it does

Htmx Realtime is an agent skill from hashgraph-online/awesome-codex-plugins. Build and review realtime and near-realtime htmx features. Use when implementing polling, load polling, job status updates, WebSockets, Server-Sent Events, htmx ws or sse extensions, streaming server-rendered fragments, multi-client updates, reconnect behavior, or deciding between polling, SSE, and WebSockets.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including assets (for example `agents/openai.yaml`). Compatibility notes: Codex, Claude Code, and other Agent Skills-compatible clients.

It sits in Backend & APIs, covering Realtime and WebSockets. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is MIT.

When your agent uses it

  • Implementing polling
  • Job status updates
  • Server-Sent Events
  • Streaming server-rendered fragments

Example prompts

  • “/htmx-realtime”

Requirements

  • Compatibility (from SKILL.md): Codex, Claude Code, and other Agent Skills-compatible clients.

What it can do on your machine

Read from SKILL.md and the folder at commit 78497e5. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are html).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Codex, Claude Code, and other Agent Skills-compatible clients.

    From compatibility in the SKILL.md frontmatter.

Context cost

Htmx Realtime loads about 1.3k tokens when it runs. Until then it costs about 81 tokens; SKILL.md has 566 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~81
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

htmx Realtime

Use this skill when a page needs updates after initial render without full refresh. Choose the simplest transport that matches update frequency, direction, and operational cost.

Transport Decision

NeedUse
Occasional status refresh for one userPolling
Load until a job completesLoad polling or bounded polling
Server-to-client event streamServer-Sent Events
Two-way low-latency messagesWebSockets
Multi-user collaborative stateUsually WebSockets, with explicit state reconciliation

Do not start with WebSockets just because updates feel realtime. Polling is easier to operate and test when updates are infrequent.

Polling

Use polling for job status, notifications, progress panels, and dashboards where a short delay is acceptable.

  • Keep the response small.
  • Choose an interval based on business need, not impatience.
  • Stop polling when the work is complete.
  • Return a final fragment that removes or disables the polling trigger.
  • Use server-side throttling or caching when many users poll the same state.
  • Avoid polling hidden tabs or offscreen widgets unless the value justifies it.

Load Polling

Use load polling when each response decides whether another request should happen. It works well for background jobs because the server can stop the loop by returning the final state without the next trigger.

Keep the next trigger near the fragment that owns the state so a final replacement removes the loop.

Server-Sent Events

Use SSE when the server pushes one-way updates to the browser:

  • notifications;
  • progress messages;
  • append-only activity feeds;
  • operational status streams.

Typical htmx SSE extension shape:

html
<section hx-ext="sse" sse-connect="/events" sse-swap="message">
  <div id="events"></div>
</section>

Server responsibilities:

  • authenticate the stream;
  • send heartbeat comments or events when infrastructure requires it;
  • close streams cleanly;
  • format event payloads as trusted HTML fragments when htmx will swap them;
  • document reconnect behavior.

WebSockets

Use WebSockets when the browser and server both send messages over a long-lived connection:

  • chat;
  • multiplayer or collaborative UI;
  • live dashboards with user actions;
  • bidirectional device or workflow control.

Typical htmx WebSocket extension shape:

html
<div hx-ext="ws" ws-connect="/socket">
  <form ws-send>
    <input name="message">
    <button type="submit">Send</button>
  </form>
  <div id="messages"></div>
</div>

Server messages should usually be HTML fragments with stable targets or out-of-band swaps. Keep message formats narrow and versionable.

State And Reconciliation

  • The server should remain the source of truth for durable state.
  • Messages should be idempotent or safely replaceable.
  • Include resource identifiers in fragments or targets so late messages do not corrupt the wrong component.
  • Decide how to handle disconnects: missed messages, reload, replay, or fetch current state.
  • For optimistic UI over WebSockets, design rollback and server confirmation explicitly.

Operational Checks

  • Does the deployment platform support long-lived connections?
  • Are proxies configured for buffering, timeout, and upgrade behavior?
  • Is authentication refreshed or rejected cleanly when sessions expire?
  • Are connection counts bounded?
  • Is backpressure handled when clients are slow?
  • Are heartbeats and reconnects tested?

Security

  • Authenticate streams and sockets just like normal endpoints.
  • Enforce authorization per message, not only at connection time.
  • Escape or sanitize user content before sending HTML fragments.
  • Avoid putting secrets in client-visible stream messages.
  • Review CSP and extension loading with htmx-security.

Testing Checklist

  • Test initial connection and expected fragment updates.
  • Test disconnect/reconnect behavior.
  • Test expired or unauthorized sessions.
  • Test malformed client messages for WebSockets.
  • Test that final polling states stop further requests.
  • Test multiple simultaneous clients when state is shared.

Avoid

  • Do not use WebSockets for simple "check every few seconds" status.
  • Do not leave infinite polling without a stop condition.
  • Do not stream unescaped user content into HTML swaps.
  • Do not assume all hosting providers treat SSE and WebSockets the same.
  • Do not couple realtime messages to page structure that may change without tests.
