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.

SkillSpector: 9 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00019 | $0.01871 |
| Opus 5 | $0.00010 | $0.00936 |
| Sonnet 5 | $0.00004 | $0.00374 |
| Haiku 4.5 | $0.00002 | $0.00187 |
Grade A, and why
catalysis-hub-api 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 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.

Catalysis Hub GraphQL API Guide
Overview
Catalysis Hub is an open-access database of DFT-calculated reaction energies and activation barriers for heterogeneous catalysis, developed at SUNCAT Center (Stanford/SLAC). It aggregates computational results from published studies, enabling researchers to search, compare, and reuse DFT data for catalyst screening and mechanism validation.
The GraphQL endpoint provides structured access to reactions, publications, and atomic structures. All data is linked to peer-reviewed publications and includes computational details (DFT code, XC functional, surface facet, coverage).
Authentication
No authentication required. Catalysis Hub is a free public service with no API keys.
GraphQL Schema
Endpoint: https://api.catalysis-hub.org/graphql
All queries use HTTP POST with a JSON query field. Responses follow the Relay connection pattern (edges/node).
Root Query Types
| Query | Description |
|---|---|
reactions |
DFT-computed reaction energies and barriers |
publications |
Published studies linked to reaction data |
systems |
Atomic structure data (ASE Atoms objects) |
species |
Chemical species involved in reactions |
Reaction Fields
chemicalComposition, surfaceComposition, facet, reactionEnergy (eV), activationEnergy (eV), dftCode (e.g. Quantum-Espresso, VASP-5.4.4), dftFunctional (e.g. RPBE), reactants (JSON), products (JSON), Equation (e.g. 0.5O2(g) + * -> O*)
Publication Fields
title, authors (JSON), journal, year (Int), doi, reactions (linked Reaction list)

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.

catalysis-hub-api is a skill published in the GitHub repository wentorai/research-plugins (291 stars, last pushed 2mo ago), licensed MIT. It adds 19 tokens to every session and 1,871 once invoked, about $0.0001 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 2026-09-03.
