abx-dl AGENTS.md

A set of instructions for coding agents working on the ArchiveBox downloader and extractor command-line tool, abx-dl.

In plain words
What is it for?
Use it when developing, inspecting plugins, running abx-dl, or verifying changes with real commands, hooks, files, and database or configuration data.
Why use it?
It gives agents the repository’s setup, testing, and code-change rules so they follow the project’s expected workflow.

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.

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

abx-dl AGENTS.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 3d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

abx-dl Agent Guide

abx-dl is the standalone downloader/extractor CLI that runs ArchiveBox plugin hooks without a full ArchiveBox collection. Keep this repo on main.

Shared Standards

  • Use uv and uv run for Python commands. Do not use system python, direct .venv/bin/python, or pip commands.
  • Prefer existing repo patterns, helper APIs, fixtures, scripts, and command surfaces.
  • Keep edits focused and minimal. Do not add wrappers, shims, aliases, or extra abstraction layers unless the current code path requires them.
  • Do not weaken assertions, skip tests, xfail tests, or accept flaky behavior.
  • No mocks, monkeypatches, fakes, simulated handlers, fake binaries, fake hooks, fake buses, or direct shortcuts around user-facing flows.
  • Tests and verification should use real CLI commands, real hooks, real installs, real subprocesses, real DB/config rows where present, real files, real URLs or pytest-httpserver, and existing fixtures.
  • Assertions must verify real correctness: exit codes, returned values, event records, filesystem contents, field values, output files, and side effects.
  • Start behavior fixes with a red failing test when a test is requested or practical.
  • Trace root causes from observed behavior. Do not paper over failures with retries, wider timeouts, broad fallbacks, or looser assertions.
  • Read README.md for the full CLI, config, plugin, and release surface.

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.
