What it does
Add Javadoc is an agent skill from OpenHands/extensions. Add comprehensive JavaDoc documentation to Java classes and methods. Use when documenting Java code, adding API documentation, or improving code documentation.
Its SKILL.md is about 290 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `.plugin/plugin.json`, `README.md` and `references/example.md`). Compatibility notes: Requires Java source files
It sits in Development, covering Technical documentation. It works with Java. The repository describes itself as: Public registry for OpenHands extensions. The licence is MIT.
When your agent uses it
- Documenting Java code
- Adding API documentation
- Improving code documentation
Example prompts
- “/add-javadoc”
Requirements
- Compatibility (from SKILL.md): Requires Java source files
What it can do on your machine
Read from SKILL.md and the folder at commit d008b81. 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.
Compatibility
Requires Java source files
From compatibility in the SKILL.md frontmatter.
Context cost
Add Javadoc loads about 292 tokens when it runs, and up to ~431 if it reads all its reference files. Until then it costs about 43 tokens; SKILL.md has 104 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.

- Include
@authortag if appropriate
Method-Level Documentation
For each public method:
- Add method-level JavaDoc describing what the method does
- Include
@paramtags for all parameters with clear descriptions - Include
@returntag describing the return value - Include
@throwstags for any checked exceptions
Style Guidelines
- First sentence should be a concise summary
- Use HTML tags sparingly (prefer plain text)
- Document preconditions and postconditions when relevant
- Include code examples with
{@code ...}for complex methods
