SkillsBench is a benchmark for measuring how effectively AI agents use modular skills—folders containing instructions, scripts, and resources—to complete specialized tasks. It helps researchers and developers evaluate both skill quality and agent behavior, including tasks that require combining multiple skills. The catalogue’s skills and instructions are evaluated as part of this workflow.
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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Prompt Injection · line 207 Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.
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 | $0.00027 | $0.02800 |
| Opus 5 | $0.00014 | $0.01400 |
| Sonnet 5 | $0.00005 | $0.00560 |
| Haiku 4.5 | $0.00003 | $0.00280 |
Grade A, and why
maven-build-lifecycle 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 6d 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.

Maven Build Lifecycle
Master Maven's build lifecycle including phases, goals, profiles, and build customization for efficient Java project builds.
Overview
Maven's build lifecycle is a well-defined sequence of phases that execute in order. Understanding the lifecycle is essential for effective build configuration and optimization.
Default Lifecycle Phases
Complete Phase Order
1. validate - Validate project structure
2. initialize - Initialize build state
3. generate-sources
4. process-sources
5. generate-resources
6. process-resources - Copy resources to output
7. compile - Compile source code
8. process-classes
9. generate-test-sources
10. process-test-sources
11. generate-test-resources
12. process-test-resources
13. test-compile - Compile test sources
14. process-test-classes
15. test - Run unit tests
16. prepare-package
17. package - Create JAR/WAR
18. pre-integration-test
19. integration-test - Run integration tests
20. post-integration-test
21. verify - Run verification checks
22. install - Install to local repo
23. deploy - Deploy to remote repo
Common Phase Commands
# Compile only
mvn compile
# Compile and run tests
mvn test
# Create package
mvn package
# Install to local repository
mvn install
# Deploy to remote repository
mvn deploy
# Clean and build
mvn clean install
# Skip tests
mvn install -DskipTests
# Skip test compilation and execution
mvn install -Dmaven.test.skip=true
Clean Lifecycle
1. pre-clean
2. clean - Delete target directory
3. post-clean
# Clean build artifacts
mvn clean
# Clean specific directory
mvn clean -DbuildDirectory=out
Site Lifecycle
1. pre-site
2. site - Generate documentation
3. post-site
4. site-deploy - Deploy documentation
# Generate site
mvn site
# Generate and deploy site
mvn site-deploy
Goals vs Phases
Executing Phases
# Execute phase (runs all previous phases)
mvn package
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.

maven-build-lifecycle is a skill published in the GitHub repository benchflow-ai/skillsbench (1,757 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 27 tokens to every session and 2,800 once invoked, about $0.0001 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.
