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 | $0.00111 | $0.00748 |
| Opus 5 | $0.00056 | $0.00374 |
| Sonnet 5 | $0.00022 | $0.00150 |
| Haiku 4.5 | $0.00011 | $0.00075 |
Grade A, and why
164-java-profiling-verify 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Java Profiling Workflow / Step 4 / Verify results
Verify performance optimizations through rigorous before/after comparison: ensure baseline and post-refactoring profiling data use identical test conditions, generate post-refactoring reports, compare metrics (memory, CPU, GC, threading), perform side-by-side flamegraph analysis, document findings in profiling-comparison-analysis-YYYYMMDD.md and profiling-final-results-YYYYMMDD.md, and validate success criteria.
What is covered in this Skill?
- Pre-refactoring baseline: run profiler with same load before changes
- Post-refactoring: generate new reports with identical test conditions
- Comparison: memory (leaks, allocations, GC), CPU (hotspots, contention), visual flamegraph comparison
- Documentation: profiler/docs/profiling-comparison-analysis-YYYYMMDD.md, profiler/docs/profiling-final-results-YYYYMMDD.md
- File naming: baseline/after suffixes, timestamp-based organization
- Validation: verify reports exist, compare metrics, identify regressions
Scope: Identical test conditions are critical. Document test scenarios. Validate application runs with refactored code before generating new reports.
Constraints
Use identical test conditions between baseline and post-refactoring. Verify both report sets are complete. Document test scenarios.
- CONSISTENCY: Use identical test conditions and load patterns for baseline and post-refactoring
- VALIDATE: Ensure both baseline and post-refactoring reports exist and are non-empty before comparison
- DOCUMENT: Record test scenarios and load patterns for reproduction
- BEFORE APPLYING: Read the reference for comparison templates and validation steps
- 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
- Verify performance fix
- Verify the performance
- Verify the memory
- Verify the threading
- Verify the GC
- Verify the profiling
- Compare before and after profiling results
- Performance benchmark
- Check for performance regressions after refactoring
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.

164-java-profiling-verify is a skill published in the GitHub repository jabrena/plinth (438 stars, last pushed yesterday), licensed Apache-2.0. It adds 111 tokens to every session and 748 once invoked, about $0.0006 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.
