Use it when writing or checking the app's Django backend, converting database object IDs into strings, configuring Codespaces access, and testing API endpoints with curl.

It provides project-specific guidance for settings, data serializers, URLs, and REST API endpoints. An API lets the app exchange data with other software through defined web addresses.

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	$0.00246	$0.00246
Opus 5.5	$0.00098	$0.00098

Security

Grade A, and why

skills-build-applications-w-copilot-agent-mode octofit_tracker_django_backend.instructions.md scanned grade A 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 2mo 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.

What it actually says

Octofit-tracker Fitness App Django backend Guidelines

Django Backend App structure

settings.py

Should always contain the following:

import os
ALLOWED_HOSTS = ['localhost', '127.0.0.1']
if os.environ.get('CODESPACE_NAME'):
    ALLOWED_HOSTS.append(f"{os.environ.get('CODESPACE_NAME')}-8000.app.github.dev")

serializers.py

serializers should convert ObjectId fields to strings

REST API Endpoints

use curl to test the endpoints

urls.py

Should always use the codespace environment variable for the URL

import os
codespace_name = os.environ.get('CODESPACE_NAME')
if codespace_name:
    base_url = f"https://{codespace_name}-8000.app.github.dev"
else:
    base_url = "http://localhost:8000"

urlpatterns = [
    path('admin/', admin.site.urls),
    path('api/', api_root, name='api-root'),
    path('api/', include(router.urls)),
]

Changes

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.
