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 | $0.00045 | $0.00898 |
| Opus 5 | $0.00023 | $0.00449 |
| Sonnet 5 | $0.00009 | $0.00180 |
| Haiku 4.5 | $0.00005 | $0.00090 |
Grade A, and why
vigilante-issue-implementation-on-java-kotlin 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 — 42 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Vigilante Java/Kotlin Issue Implementation
Focus
- Read the prompt for detected tech stacks, process hints, and JVM build signals before changing code.
- Keep changes scoped to the issue and prefer the repository's actual Gradle or Maven workflow over invented commands.
- In mixed Java/Kotlin repositories, follow the conventions of each touched language instead of forcing one style across the whole repo.
JVM Tooling Workflow
- Build/test validation: use repository-standard Gradle or Maven tasks for the smallest affected scope first, then broaden only when shared modules or integration boundaries require it. Prefer commands the repo already documents or wires into CI.
- Formatting and style: use the repository's existing formatter or style tooling when present. For Java, this may be Checkstyle, Spotless, or equivalent. For Kotlin, this may be ktlint, detekt formatting, Spotless, or equivalent. Do not introduce a new formatter or broad cleanup just because a tool exists in the ecosystem.
- Static analysis: run repo-standard static analysis when configured, such as SpotBugs, Checkstyle, detekt, ktlint, Error Prone, PMD, or equivalent. If none is configured, rely on the repository's normal build/test path rather than inventing a new lint stack.
- Dependencies: prefer the standard library or existing dependencies when they already cover the need. When adding or updating dependencies, keep Gradle or Maven metadata consistent and preserve any dependency-locking or version-catalog workflow already used by the repo.
Java/Kotlin Style
- Java: follow standard Java conventions already used by the repository. Keep classes cohesive, prefer explicit names, use checked or unchecked exceptions consistently with local patterns, and avoid unnecessary framework abstraction.
- Kotlin: follow Kotlin coding conventions for naming, file organization, null-safety, and expression-oriented style. Prefer immutable values with
valunless mutation is required. Use idiomatic scope functions only when they improve clarity. - Documentation: when touching documented APIs, preserve the repository's documentation style. Use Javadoc or KDoc only where the codebase already expects it or where exported/public API changes need it.
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.

vigilante-issue-implementation-on-java-kotlin is a skill published in the GitHub repository aliengiraffe/vigilante (40 stars, last pushed yesterday), licensed Apache-2.0. It adds 45 tokens to every session and 898 once invoked, about $0.0002 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 2026-08-30.
