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.

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 | $0.00095 | $0.00640 |
| Opus 5 | $0.00048 | $0.00320 |
| Sonnet 5 | $0.00019 | $0.00128 |
| Haiku 4.5 | $0.00010 | $0.00064 |
Grade A, and why
170-java-documentation 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 7d 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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Java Documentation Generator with modular step-based configuration
Generate comprehensive Java project documentation through a modular, step-based interactive process that covers README.md, package-info.java, and Javadoc. This is an interactive SKILL.
What is covered in this Skill?
- README.md generation for single-module and multi-module Maven projects
- package-info.java creation with basic/detailed/minimal documentation levels
- Javadoc enhancement: comprehensive
@param/@return/@throwstags - File handling strategies: overwrite/add/backup/skip
- Final documentation validation with
./mvnw clean compileand./mvnw javadoc:javadoc
Constraints
Before applying any documentation generation, ensure the project validates. If validation fails, stop immediately — do not proceed until all validation errors are resolved.
- MANDATORY: Run
./mvnw validateormvn validatebefore applying any documentation generation - SAFETY: If validation fails, stop immediately — do not proceed until all validation errors are resolved
- BEFORE APPLYING: Read the reference for detailed good/bad examples, constraints, and safeguards for each documentation generation pattern
- EDGE CASE: If request scope is ambiguous, stop and ask a clarifying question before applying changes
- EDGE CASE: If required inputs, files, or tooling are missing, report what is missing and ask whether to proceed with setup guidance
When to use this skill
- Improve the code with documentation
- Apply documentation
- Refactor the code with documentation
- Generate README or developer documentation for a Java project
- Document Java APIs architecture or project workflows
Workflow
- Validate project before documentation changes
Run ./mvnw validate or mvn validate and stop immediately if validation fails.
- Read documentation reference and gather scope
Read references/170-java-documentation.md and identify required outputs (README, package-info, Javadoc enhancements).
What ships with it
1 file 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.
- 7d ago First seen · 60 lines · 95 tokens per session scan A d01cac34b720
170-java-documentation is a skill published in the GitHub repository jabrena/plinth (438 stars, last pushed yesterday), licensed Apache-2.0. It adds 95 tokens to every session and 640 once invoked, about $0.0005 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.
