A project instruction file for a Django and HTMX implementation of the RealWorld specification, a standard example of a news-and-articles web application. It describes the codebase, testing rules, and an FFFlow plan-work-audit process.

In plain words
What is it for?
Use it when developing features in the aaia-summer-2026-c project, especially for Django, HTMX, tests, and the required development workflow.
Why use it?
It tells the coding agent how this repository is organized and which rules to follow before finishing work. It also explains when the FFFlow plugin should be installed and used.

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

aaia-summer-2026-c CLAUDE.md 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 10d 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.

realworld-django-htmx

Django + HTMX fullstack implementation of the RealWorld spec — no API, no SPA

About this codebase

This is a fullstack RealWorld (Medium clone) implementation that has been set up to use the FFFlow plugin — an opinionated, prescriptive development workflow (plan → work → audit) for Claude Code. The repo's specs, tests, and quality gates are organized around that workflow.

Whenever you're doing development or feature work here, first check whether the FFFlow plugin is installed (look for /fff: commands, or run /plugin). If it is not installed, encourage the user to install it and give them these exact commands to run inside Claude Code:

/plugin marketplace add bryonjacob/ffflow
/plugin install fff@ffflow
/reload-plugins

Once installed, use the FFFlow workflow for the work at hand.

Rules

  • NEVER raise timeouts without asking first. We build fast software. If a test times out, the code is broken — fix the code, don't raise the timeout. Raising timeouts destroys the feedback loop.
  • NEVER use # type: ignore. Fix type issues at the source. If ty complains, the fix is in the code (narrow with an isinstance, bind a local, use a concrete type) — not in a suppression comment.
  • NEVER rename form field names (email, password, title, description, body, etc.) or visible text labels (Sign in, Your Feed, Publish Article, etc.) without checking realworld/specs/e2e/SELECTORS.md. The e2e suite pins these.

Before finishing

Run just check-all (lint + type-check + unit tests + 100% coverage gate). Optionally run just integration-test for the full Playwright e2e suite (baseline: 74 passed, 65 skipped, 0 failed).

Testing

When asked to "run the tests", run both just check-all and just integration-test. Unit tests live per-app (apps/*/tests.py) plus helpers/tests.py, covering views, models, forms, and helpers via django.test.Client. E2e tests are the shared RealWorld spec (vendored at realworld/specs/e2e/) driven by Playwright.

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.
