v2.1.0

Caveman 2.1.0

caveman learn

• Context-depth report: each session's peak context-window share, bucketed, with over-30%/over-50% counts.
• Report UI: TLDR summary, two-card savings (proxy-measured saved-so-far + replay could-have-saved), 30-day list-price cost illustration.

CLI

• Persisted shortcut and token telemetry (feat/cli).

Skill and hooks

• Skill forbids caveman phrasing that adds tokens; names defect/ticket text.
• Hooks resolve punctuated /caveman levels and stop prose firing mode triggers; degrade instead of crashing when a sibling hook file is missing.
• Compress: indented fence markers no longer break inline-code validation.
• Installer installs Cursor skills globally; SSRF block errors name the allowlist escape hatch; opencode agents drop provider-less model values.

Docs

• New twenty-chapter technical manual under docs/technical/.
• README rewritten as a landing page: proxy-first install, caveman learn showcase with a real report screenshot, skills-as-images.

All local numbers remain inferred; benchmark numbers remain benchmark_counterfactual. Installer pins bumped to v2.1.0.
