Giant Salamander Skillbox 1.0.0

Giant Salamander Skillbox 1.0.0

Release tag: skillbox-2026.08.16

Stable promotion

This is the first stable four-skill release of Giant Salamander Skillbox. The published release-candidate bundle was installed and operated successfully in Codex, ChatGPT Work, and Claude Code before promotion.

• Includes readatable 0.7.1.
• Includes reviewcitation 0.3.4.
• Includes samplesize200 1.0.0-rc.9. rc.9 updates product and distribution documentation only; engine 0.6.9 and the numerical methods are unchanged.
• Includes draftcostsheet 0.2.2.
• Provides one all-in-one plugin with Codex and Claude Code manifests, plus four single-skill ZIPs.

The accepted rc.4 bundle remains available as an immutable prerelease. Stable promotion uses a new tag, bundle version, filename, and checksums rather than rewriting the accepted prerelease.

Giant Salamander Skillbox — 2026.08.02 rc9

This prerelease corrects the English Giant Salamander Skillbox cheat sheet.
The corrected sheet identifies the current all-in-one plugin as
giant-salamander-skillbox-1.0.0-rc.3.zip.

Included skills

• readatable 0.7.1
• reviewcitation 0.3.4
• samplesize200 1.0.0-rc.7

Scope

• replaces skillbox-cheatsheet-en.pdf with the corrected one-page PDF
• republishes the remaining rc8 assets unchanged so rc9 remains a complete
  distribution set
• keeps the all-in-one plugin at 1.0.0-rc.3
• keeps the Codex and Claude Code marketplace catalogs pinned to rc8 because
  the plugin source and ZIP are byte-identical

No skill instructions, calculation formulas, rounding rules, registered
procedures, numerical results, plugin manifests, or installation ZIPs changed.
The PowerPoint source file is retained as an editing source and is not a public
release asset.
