django-htmx

A set of coding guidelines for Django applications that use HTMX to add interactive behavior while keeping HTML rendered by the server. It also covers Tailwind CSS for styling and PostgreSQL as the database.

In plain words
What is it for?
Use it to build server-rendered web pages with Django, add updates such as lists, dialogs, and notifications with HTMX, and organize models, views, forms, URLs, templates, and static files.
Why use it?
It provides a shared structure for organizing Django apps, templates, reusable page parts, and HTMX responses. This helps avoid unnecessary client-side application code for interactive pages.

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.

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.

Security

Grade A, and why

django-htmx 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 2d 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.

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.
