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.

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 | $0.00992 | $0.00992 |
| Opus 5 | $0.00496 | $0.00496 |
| Sonnet 5 | $0.00198 | $0.00198 |
| Haiku 4.5 | $0.00099 | $0.00099 |
Grade A, and why
er-server AGENTS.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 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.
How it starts

Project Overview
EarthRanger (DAS - Domain Awareness System) is a Django-based web application for wildlife conservation and domain awareness. This is a multi-tenant system that tracks wildlife, manages events, handles patrols, and provides real-time monitoring capabilities.
Architecture Overview
Django Apps Structure
accounts/- User management, permissions, and authenticationactivity/- Events, patrols, and alerting systemobservations/- Animal tracking, GPS data, and subject managementmapping/- GIS integration, spatial data, and map servicessensors/- IoT device handlers and data ingestionanalyzers/- Real-time analysis (geofencing, proximity, immobility detection)tracking/- Source plugins for various GPS/telemetry providersreports/- Report generation and data distributionutils/- Shared utilities and common functionality
Key Technologies
- Django 3.2
- Django REST Framework (for API development)
- python 3.10
- pytest for unittesting
- Celery (for background tasks)
- Redis (for caching and task queues)
- PostgreSQL 16
- Docker and Kubernetes for deployment
Multi-Tenant Architecture
This system is multi-tenant aware. Most models have a das_tenant field that isolates data between tenants.
Key considerations:
- Data isolation at the database level
- Tenant context in requests and background tasks
- Tenant-specific configurations and permissions
- Cross-tenant queries require special authorization
Configuration
Settings Structure
das_server/settings.py- Base settingsdas_server/local_settings_docker.py- Local development and prod overrides- Environment variables configured via
.envfile for local overrides
Key Environment Variables
DJANGO_SETTINGS_MODULE- Points to settings module- Database configuration via django-environ
DEBUGandDEVflags for development mode
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.

er-server AGENTS.md is an instructions file published in the GitHub repository PADAS/er-server (11 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 992 tokens to every session, about $0.0050 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
