Token cost

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.

Security

Grade A, and why

release-checklist 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 2d 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.

Pre-Release Checklist

Run through the full release prep checklist for PerformanceMonitor. $ARGUMENTS is the target version (e.g., 3.3.0).

Scope (since v3.3.0): the Full Dashboard and the CLI Installer are DEPRECATED and OUT of this process — they ship no release artifacts and get no live install/upgrade testing here. They still build and their test suites still run in CI on the release event, and they inherit the single <Version> with everything else in the tree (below). The release artifacts are: Lite (zip + Velopack Setup.exe), the Darling service zip, and the Darling Viewer Setup.exe.

Checklist

Work through each step in order. Report status as you go. If a step fails, stop and report.

1. Version Bumps

Bump <Version> in Directory.Build.props. That is the whole step — one line, one file.

Every project in the tree inherits it, and AssemblyVersion / FileVersion / InformationalVersion derive from it at build time. Do not add any of those four elements to a csproj: ProductVersionDeclarationTests fails the build on a second <Version> property anywhere in the tree, on a re-added derived property, and on a workflow or script that reads a version from any path but Directory.Build.props.

This replaced six independently hand-bumped csproj files (#3222). Two of them had been sitting three releases behind, deprecated/Dashboard/Dashboard.csproj was declaring 3.6.0 while its binary stamped 3.3.0.0, and the release gate took its judgement from that file — so nothing in CI compared the version it gated on against the version the artifacts were named with. Both now read the file above.

Verify no other files contain hardcoded version strings that need updating.

2. CHANGELOG

Ensure CHANGELOG.md has an entry for the new version with:

  • Important section if there are store/schema changes or breaking changes (Darling store migrations, PG runtime upgrades with offline windows, operator actions required post-upgrade)
  • Added section for new features
  • Changed section for behavior changes
  • Fixed section for bug fixes
  • Reference links at the bottom for all issue numbers

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.
