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.
npx agentmods add instructions/archivebox/abx-dl/agents-mdgit clone --depth 1 https://github.com/ArchiveBox/abx-dlWhat 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 | $0.00704 | $0.00704 |
| Opus 5 | $0.00352 | $0.00352 |
| Sonnet 5 | $0.00141 | $0.00141 |
| Haiku 4.5 | $0.00070 | $0.00070 |
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.

The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
uvanduv runfor Python commands. Do not use systempython, direct.venv/bin/python, orpipcommands. - 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.mdfor the full CLI, config, plugin, and release surface.

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.

abx-dl AGENTS.md is an instructions file published in the GitHub repository ArchiveBox/abx-dl (141 stars, last pushed 4d ago), licensed MIT. It adds 704 tokens to every session, about $0.0035 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
