Install the XLSX skill

Skills CLI (Claude Code, Codex, Cursor and others)

npx skills add https://github.com/ThinkInAIXYZ/deepchat --skill xlsx

Claude Code, by hand (all projects)

git clone --depth 1 https://github.com/ThinkInAIXYZ/deepchat.git /tmp/deepchat
mkdir -p ~/.claude/skills
cp -R /tmp/deepchat/resources/skills/xlsx ~/.claude/skills/xlsx

For one project only, copy the folder into .claude/skills/ in that project instead. The agent picks it up when a task matches its description.

Until it is used, xlsx costs about 14× less than the median MCP server we measured (1,362 tokens on every turn). Installing all 24 skills from ThinkInAIXYZ/deepchat would load 1,435 tokens of descriptions. Skills vs MCP study

  6. deepchat-releaseThinkInAIXYZ/deepchat

    Prepare and publish DeepChat releases in this repository. Use when Codex needs to bump the app version, update CHANGELOG.md, keep release notes bilingual from v1.0.1 onward with English bullets first and Chinese bullets second, run release checks, create or update versioned release branches such as release/v1.0.1, continue a half-finished release, fast-forward main with the documented release flow, create or push version tags, or clean up release branches after publishing.

  7. deepchat-sddThinkInAIXYZ/deepchat

    Use before substantial DeepChat code, configuration, documentation, test, build, feature, issue, refactor, or architecture changes that need a durable RFC and an explicit execution path. Skip trivial style fixes, small localized logic changes, routine docs edits, and simple bugs unless the developer asks for SDD. Use plan.md as the only separate tracker when needed, default to implementation-first validation, and ask before optional GitHub issue sync unless the developer explicitly requested sync.

  8. deepchat-sdd-cleanupThinkInAIXYZ/deepchat

    Use only when a developer explicitly asks to clean, prune, tidy, or organize DeepChat SDD documentation after implementation and validation. Scans docs/features, docs/issues, and docs/architecture; prefers multi-agent review when available; removes completed issue docs when a linked GitHub issue is closed or implementation and validation evidence proves the bug no longer exists, drops stale plans and legacy task files from completed feature or architecture goals, and deletes obsolete feature or architecture docs.
