What is station AGENTS.md?

Operating instructions for Station, including a coding-agent checklist, project overview, setup guidance, and rules for handling live station data. They emphasize reading subsystem notes and checking actual definitions before editing.

Use them when debugging or changing Station subsystems, configuration, commands, or live data, while verifying behavior against the code.

They help prevent changes based on guessed names or stale settings and protect live project state from accidental modification.

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	$0.07598	$0.07598
Opus 5.5	$0.03039	$0.03039
Sonnet 5.5	$0.01520	$0.01520

Security

Grade B, and why

station AGENTS.md scanned grade B 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.

AGENT.md

This file gives Claude Code and other coding agents the current operating guidance for this repository.

First Principles

Read the relevant docs before touching a subsystem. The example/doc/ folder contains subsystem notes. Use these as maintenance references, but verify against code when they disagree.
Check runtime overrides. Defaults live in station/constants.py, but station_data/constant_config.yaml overrides them at import time. Always inspect both when behavior depends on configuration.
Verify names and signatures before calling or editing. Use rg to find definitions and call sites. Do not infer parameter names, constants, action names, or YAML fields from memory.
Treat station_data/ as live station state. Reading is allowed for debugging. Ask the user before modifying real station data unless the request explicitly asks for that modification.
Stay inside the current station checkout unless asked otherwise. When debugging live station state, only read or write the current repository and its own station_data/ or station_multistart/ paths. Do not inspect sibling checkouts such as ~/station_2, ~/station_3, or other ~/station_* directories unless the user explicitly asks for a cross-station check or names that checkout.
Keep disposable local probes in /tmp. Use tests/test_*.py, tests/debug_*.py, or tests/analysis_*.py only for files that should be visible to git. Use /tmp directly for generated API/debug snapshots, Sage/CAS probes, and other throwaway local test output.
Use repository file helpers for persistent station data. Use station/file_io_utils.py for atomic YAML/text writes and safe directory creation.

Coding Agent Checklist

Before making code changes:

Run git status --short and identify unrelated user changes.
Read this file, then read the subsystem doc listed in the Documentation Map.
Inspect station_data/constant_config.yaml when configuration affects the issue.
Use rg to find the live implementation, constants, tests, and call sites.
Decide which files are code, docs, tests, or live station state before editing.

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.
