At a glance
A skill your agent uses when targeting The Astrophysical Journal (ApJ) or its Letters companion (ApJL), or deciding whether an astrophysics manuscript fits this AAS venue.
- Targeting The Astrophysical Journal (ApJ)
- SKILL.md covers Journal positioning, When to trigger, Scope & topic fit and Method & evidence bar, plus 6 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
- Its Letters companion (ApJL)
What it does
The Astrophysical Journal is an agent skill from franklee16/academic-research-skills. Use when targeting The Astrophysical Journal (ApJ) or its Letters companion (ApJL), or deciding whether an astrophysics manuscript fits this AAS venue. Encodes the journal's fit, framing, method-and-evidence bar, house style, official-submission re-check, and desk-reject heuristics.
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Research & Science, covering Physical and earth sciences. The repository describes itself as: Comprehensive collection of Claude Code skills for academic research in economics, finance, and social sciences.
When your agent uses it
- Targeting The Astrophysical Journal (ApJ)
- Its Letters companion (ApJL)
- Deciding whether an astrophysics manuscript fits this AAS venue
Example prompts
- “/the-astrophysical-journal”
What it can do on your machine
Read from SKILL.md and the folder at commit 9a4b2db. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
The Astrophysical Journal loads about 1.8k tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 795 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 795 words (~1,810 tokens).
“The Astrophysical Journal is the flagship archival research journal of the American Astronomical Society (AAS), published by IOP Publishing, and the primary record for astrophysics across theory, observation, and simulation. Its companion ApJL (The Astrophysical Journal Letters) publishes shorter, high-impact…”

When should I use The Astrophysical Journal?
The Astrophysical Journal fits situations like: targeting The Astrophysical Journal (ApJ); its Letters companion (ApJL); deciding whether an astrophysics manuscript fits this AAS venue.
How do I install The Astrophysical Journal in Claude Code?
Run `npx skills add franklee16/academic-research-skills --skill the-astrophysical-journal -a claude-code`. Or copy the skill folder (Awesome-Journal-Skills-main/English-NaturalScience-Journal-Skills/skills/the-astrophysical-journal in franklee16/academic-research-skills) into .claude/skills/the-astrophysical-journal in your project. Claude Code loads it when a task matches its description.
How do I install The Astrophysical Journal in Codex?
Run `npx skills add franklee16/academic-research-skills --skill the-astrophysical-journal -a codex`. Or copy the skill folder (Awesome-Journal-Skills-main/English-NaturalScience-Journal-Skills/skills/the-astrophysical-journal in franklee16/academic-research-skills) into .agents/skills/the-astrophysical-journal in your project.
