Summary

Remove the bundled office-* skills (skills/office-docx, office-pdf, office-pptx, office-xlsx) and the now-empty embedded skills mechanism. This is the final cleanup of the retired OfficeCLI line: the bundled OfficeCLI binary and its skill bundle were already retired in #1494; this drops the native office-* replacement skills and the packaging/runtime wiring that shipped them.

Why

  • The office-* skills are the only skills left in skills/; with them gone there is nothing to bundle.
  • electron-builder.config.ts still ships rootDir/skills, and the desktop runtime still resolves a skills product resource and sets DSH_BUNDLED_SKILL_DIR. With no bundled skills, this wiring is dead and would reference a missing source directory at build time.
  • Removing them keeps the repo clean and removes the build/runtime dependency on a skills directory that no longer exists.

Office files remain a supported product capability: the model can still generate or edit .docx/.xlsx/.pptx by writing Python (python-docx / openpyxl / python-pptx) through the bundled uv runtime, so the README/site "Office file handling" copy is unchanged.

How To Verify

  • pnpm install --frozen-lockfile (from worktree root) — clean.
  • cd packages/desktop-electron && pnpm exec vitest run35 files / 340 tests pass (was 34/339; the to: "skills" extraResources assertion was dropped).
  • pnpm run typecheck in packages/desktop-electron — clean.
  • git grep -rin "officecli\|DSH_BUNDLED_SKILL_DIR\|office-docx" — no tracked hits.

Risk

  • Low. The DSH skill-filesystem provider reads DSH_BUNDLED_SKILL_DIR only when present (config.bundledSkillDir ?? (includeDefaultRoots ? process.env.DSH_BUNDLED_SKILL_DIR : undefined)); with it absent it simply supplies no bundled-skills root.
  • The desktop runtime change (buildDshEnvironment() no longer sets DSH_BUNDLED_SKILL_DIR) is covered by updated unit tests; the packaged-app smoke path was not run here.

Summary by CodeRabbit

  • Changes
    • Removed bundled office-document tools for creating and validating Word, PDF, PowerPoint, and Excel files.
    • Desktop packaging no longer includes these document tools or related resources.
    • Updated third-party notices and supporting documentation to reflect the streamlined product contents.
    • Smoke tests and packaging checks now align with the reduced set of bundled capabilities.

…nism

Remove the bundled office-* skills (docx/pdf/pptx/xlsx) and the now-empty
embedded skills mechanism. With no skills left to ship, drop the skills
extraResources entry from electron-builder, the skills product-resource and
DSH_BUNDLED_SKILL_DIR wiring from the desktop runtime, and the ci-smoke
assertions/snapshot fields that checked for the bundled skills.

The model can still generate or edit Office documents by writing Python
(openpyxl / python-docx / python-pptx) through the bundled uv runtime, so the
Office-file handling copy in README/site stays.

This also retires the last residual OfficeCLI artifacts from the local tree
(the officecli binary and the officecli/office-route research docs) which were
already removed from git in the earlier OfficeCLI retirement (#1494).

Review Change Stack

📝 Walkthrough

Walkthrough

The change removes bundled Office skills and their Python tooling. Electron packaging and DSH environment handling no longer reference skill resources. CI smoke tests and product resource tests remove skill discovery and expectations. Repository descriptions are updated.

Changes

Bundled Office skill removal

Layer / File(s) Summary
Product resource and environment cleanup
packages/desktop-electron/electron-builder.config.ts, packages/desktop-electron/electron-builder-app-update.test.ts, packages/desktop-electron/src/main/dsh-product-home.ts, packages/desktop-electron/src/main/dsh-product-home.test.ts, packages/desktop-electron/src/main/index.ts
Electron packaging no longer includes the repository-level skills directory. Product resource resolution and DSH environment construction no longer expose bundled skill paths. Related tests remove those expectations.
Smoke-test contract cleanup
packages/desktop-electron/scripts/ci-smoke.ts, packages/desktop-electron/scripts/ci-smoke.test.ts
The smoke snapshot no longer contains skillNames. Product inspection, assertions, fixtures, and success output no longer reference bundled Office skills.
Office skill and metadata removal
skills/office-docx/*, skills/office-pdf/*, skills/office-pptx/*, .gitignore, THIRD_PARTY_NOTICES.md
The Office skill definitions, Python project files, validation scripts, SVG-to-PPTX implementation, native object converters, and PPTX packaging modules are deleted. Repository comments and third-party notices use broader Office document wording.

Closing: this solved the wrong problem. The goal was a repo junk-file scan; instead it deleted the four native office-* skills — which are not OfficeCLI leftovers but its replacement (introduced in #1491 as the #1273 pipeline, i.e. the current Office capability route) — plus the bundled-skills packaging/runtime wiring. Dropping them is a product capability regression that needs an explicit product decision, not a chore cleanup. The wiring removal itself was correctly scoped and can be revived if a future decision does retire the bundled skills.
