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

app-release 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 3d 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

app-release

Use this skill when you need to publish a new version of the Skill Lake application.

Workflow

  1. Check Prerequisites: Ensure you are on the main branch and have no uncommitted changes.
  2. Determine Version: Ask the user for the new version number (e.g., 1.1.8) if not provided.
  3. Execute Release: Run the ./release.sh script with the new version as an argument.
  4. Verification: Confirm that the build succeeded, the DMG was created, and the release was pushed to GitHub and the Homebrew tap.

Usage

./release.sh <new_version>

Example:

./release.sh 1.1.8

Features

  • Code Validation: Automatically runs flutter analyze and checks formatting before building.
  • Automated Build: Builds the macOS app in release mode.
  • DMG Packaging: Creates a signed DMG package for easy installation.
  • Git Automation: Handles version bumping in pubspec.yaml, commits, tagging, and pushing.
  • GitHub Integration: Creates or updates a GitHub Release and uploads the DMG.
  • Homebrew Sync: Automatically updates the Homebrew Cask in the dedicated tap repository.
  • UI Sync: Ensures the version displayed in the "About" dialog matches the released version using package_info_plus.

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.
