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

standalone-python-scripts 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 1mo 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 it actually says

Standalone Python Scripts

Use this header:

#!/usr/bin/env -S uv run --script
# /// script
# requires-python = ">=3.13"
# dependencies = []
# ///
  • Specify dependencies via the dependencies variable in the above comment
  • Do not install packages with pip or any other package manager, assume packages will be installed when needed using uv run --script.
  • Use click for CLI interfaces
  • When listing constants at the top of the file, include a newline between entries and (for non-obvious constants) document each constant with a comment:
# matches full lowercase git shas (short or full)
SHA_REGEX = re.compile(r"^[0-9a-f]{7,40}$")

# matches any char not allowed in dns labels
SAFE_CHARS_REGEX = re.compile(r"[^a-z0-9-]")

DEFAULT_ENVIRONMENT_NAME = "production"
DEFAULT_SERVICE_NAME = "Postgres"

CLI Output and Logging

  • Use structlog_config for logging. Read the usage guide: @https://github.com/iloveitaly/structlog-config/
  • Use logging for operational/debugging info that goes to structured logs.
  • Use CLI output for user-facing messages the user needs to see during normal execution (status updates, warnings, errors). Color these messages.

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.
