dismech: Skill for Claude Code

.claude/skills/aop-wiki/SKILL.md

aop-wiki is a skill for Claude Code from monarch-initiative/dismech. It costs 110 tokens per session (3,871 once invoked), scanned A, original, BSD-3-Clause.

A command-line tool for searching and reading the AOP-Wiki, a scientific database of Adverse Outcome Pathways: chains linking biological events to harmful outcomes. It works with Key Events and the relationships between them.

In plain words
What is it for?
Use it to find pathways, stressors, mechanisms, adverse outcomes, Key Events, and evidence about relationships between those events.
Why use it?
It avoids writing custom code to download and parse AOP-Wiki data. It also helps make lookups repeatable by keeping the data location and source version explicit.

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

aop-wiki 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 6d 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

The opening of the file, as written. The whole thing — 296 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AOP-Wiki access via aop-wiki-cli

aop-wiki-cli is an installable module — gingin77/aop_wiki_cli. It owns the XML download, the parsers, and the entity model; do not add downloading or parsing code to dismech, and do not have dismech code read its XML or cache files. If a query needs something the CLI cannot do, add a command there.

uvx --from git+https://github.com/gingin77/aop_wiki_cli aop-wiki-cli --help

That form tracks the repository's default branch, so the tool can change under you between runs. Append @<tag-or-commit> to pin when a result has to be reproducible — and record the pin next to the snapshot date, since the two together are what make a lookup repeatable.

Installed into an environment it is just aop-wiki-cli <command>; from a clone, uv run aop-wiki-cli <command>. All three reach the same console script, so every example below is written as the bare aop-wiki-cli form.

The data directory is the thing to get right

The tool no longer carries its own location, so you choose where its data lives — inputs, outputs, dated caches and logs all resolve under one data directory, decided at call time in this order:

  1. --data-dir <path> — a global option, and it must come before the subcommand: aop-wiki-cli --data-dir ~/aop-data find-kers-for-events …
  2. $AOP_WIKI_CLI_DATA_DIR
  3. the current working directory

It derives outputs/, outputs/cache/, xml_inputs/, logs/, inputs/ and curated/ beneath whichever of those wins.

Two consequences worth internalizing before the first run.

The cwd fallback is silent and it is the dangerous one. Run a command from the dismech checkout with no --data-dir and no environment variable, and the tool will create outputs/, xml_inputs/ and logs/ inside dismech — none of which belong in this repo. Always pin the data directory, and never pin it at a dismech checkout or worktree.

A fresh data directory has no cache, so the first command run against one downloads the ~50 MB XML export and parses it. Point at a directory that already holds a snapshot unless refreshing is the actual goal.

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.
