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 | $0.00063 | $0.00459 |
| Opus 5.5 | $0.00025 | $0.00184 |
| Sonnet 5.5 | $0.00013 | $0.00092 |
| Haiku 4.5 | $0.00006 | $0.00046 |
Grade A, and why
usage-monitor-nsis-installer 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 8d 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.
What it actually says
Usage Monitor NSIS Installer
Build and troubleshoot the Windows installer while preserving the repository's known-good NSIS rules.
Workflow
- Read AGENTS.md, README.md, build.gradle.kts, and src/installer/UsageMonitor.nsi first.
- Prefer the Gradle path first:
gradlew.bat createDistributablegradlew.bat packageInstaller
- Use the helper build-with-icon.ps1 only when the task specifically needs the icon-patched Windows executable plus a local installer build.
- Validate the expected output:
build/compose/binaries/main/app/Usage Monitorbuild/installer/UsageMonitor-Setup-<version>.exe
- When debugging installer freezes, use the repository's known lessons:
- Freeze at 99 percent strongly suggests compression trouble.
- Freeze on the finish screen strongly suggests a blocking process launch.
- Keep
SetCompressor zlibin the NSIS script. - Avoid blocking success flows with
ExecWait.
- Preserve the current installer behavior unless the user explicitly wants to change it:
- user-level install
- uninstall registry handling
- Start Menu and desktop shortcuts
- optional Windows auto-start entry
Guardrails
- Do not assume NSIS is installed; verify it first on Windows.
- Do not replace the Gradle packaging path with ad hoc file copies unless the user is explicitly debugging the helper flow.
- When changing installer behavior, inspect both src/installer/UsageMonitor.nsi and the related Gradle tasks in build.gradle.kts.
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.

usage-monitor-nsis-installer is a skill published in the GitHub repository edilsonvilarinho/usage-monitor (16 stars, last pushed yesterday), licensed MIT. It adds 63 tokens to every session and 459 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-10-16.
