tessera

One mod for Claude Code, Windows and CJK first: pasted-image and text previews in any terminal, themed replies with CJK-correct tables and charts, long edit diffs folded, unfinished tasks carried into the next session, and guards for multi-agent runs and Traditional Chinese writing

Validation on 2.1.302: Passed
Scanned revision: d6a7e3954c9b
Marketplace passed: og-matcha
UI rewrite review: UI hook source contains control-character strings. Review any values passed to next() as rewritten props.text; the scanner does not trace whether these strings reach that call. hooks/guard.ts:188, hooks/peek.ts:98, hooks/peek.ts:99, hooks/render.tsx:218, hooks/vendor/mermaid-text.js:4, hooks/vendor/prism.js:1

These are the hooks and API calls reported by claude plugin validate. Access levels describe the widest reach of those calls and are not safety ratings. Validation is a static check, not a runtime test, and a passing result does not prove that a mod works or is safe. How the scan works.
