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.

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 | $0.00121 | $0.02612 |
| Opus 5 | $0.00060 | $0.01306 |
| Sonnet 5 | $0.00024 | $0.00522 |
| Haiku 4.5 | $0.00012 | $0.00261 |
Grade A, and why
journal-abbrev 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 9d 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 — 217 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Journal Abbreviation Lookup
Look up journal/magazine name abbreviations using a multi-source cascade: JabRef database (~25K journals) → AbbrevISO API (ISO 4) → NLM Catalog (MEDLINE).
Critical rule: Always use jabbrv.py for lookups. Never guess abbreviations — even common journals have non-obvious abbreviations.

Output format
Stdout is a stable JSON envelope when the CLI is not attached to a terminal
(piped or captured by an agent), and a human table/indented view when run on a
TTY. To force a format: --format json|table|human|auto. --json remains as a
back-compat alias for --format json. Flags may appear before or after the
subcommand.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

journal-abbrev is a skill published in the GitHub repository HK-hub/AgentSkills (6 stars, last pushed 25d ago), licensed MIT. It adds 121 tokens to every session and 2,612 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
