Modernization workspace kit
Publish repository-scoped assets that plugin installation does not activate automatically, with preview as the default and managed ownership for every written destination.
When to invoke
- "Preview the workspace customizations for this modernization track."
- "Install the stage agents and prompts in this repository."
- "Add the traceability automation."
- "Uninstall only files managed by the workspace kit."
Inputs
Use $ARGUMENTS as script options. Require an explicit target and profile. --apply authorizes the planned transaction; --uninstall selects an archive-based uninstall plan. Do not infer --apply.
Policy and mechanism
This skill is the mechanism. The asset policy lives in workspace-kit.json at the root of the plugin that
carries this generated copy, so each modernization track publishes its own assets through the same tested
publisher.
| Manifest key |
Meaning |
kitName |
Label used in reports and transaction temp directories. |
stateFile |
Target-relative managed-state path; the backup path derives from it. |
globalInstructions |
Package-relative source for the repository-wide instructions file. |
agents, prompts |
File names published from the package agents/ and prompts/ directories. |
skills |
Skill directory names published as trees. |
coreInstructions, workshopInstructions |
Instruction file names per profile. |
automation |
source and destination pairs for workflows and scripts. |
A missing or malformed manifest is a hard error; the publisher never falls back to defaults.
Profiles
| Profile |
Published assets |
core |
Global instructions, stage agents, project skills, and core instructions. |
workshop |
core plus workshop instructions and stage prompts. |
automation |
The manifest's automation entries only. |
full |
Union of workshop and automation. |
Procedure
Preview the selected profile:
python3 scripts/install_workspace_kit.py --target <repository> --profile workshop
Review every create, update, unchanged, unmanaged-identical, retired, preserved, and conflict result.
Apply only after approval by repeating the command with --apply.
Preview the same profile again and require every managed destination to be unchanged.
Preview uninstall with --uninstall; add --apply only after reviewing archive and preserve actions.
Safety
- Preview mode writes no files.
- Any unmanaged or modified managed destination blocks the complete install or update transaction.
- New content and managed state are staged before commit; a commit failure restores prior files and state.
- Existing identical unmanaged files are not silently adopted.
- Paths that escape the target or traverse symlinks are rejected.
- Managed state is written atomically to the manifest's
stateFile.
- Uninstall archives unchanged managed files and preserves modified files.
- The publisher does not install dependencies, access networks, stage Git changes, commit, push, deploy,
change repository settings, or mutate infrastructure.
- Switch profiles only after previewing and uninstalling the profile recorded in managed state.
Progressive disclosure and bundled resources
scripts/install_workspace_kit.py: transactional preview, apply, update, and uninstall publisher.scripts/test_install_workspace_kit.py: profile, conflict, idempotence, rollback, archive, manifest, and path-safety tests.
Limits
- This skill does not install or update the plugin itself.
- Project copies are publication artifacts, not a second canonical source.
- VS Code prompts remain VS Code-only after publication.
- Automation entries are published as declared; the publisher does not validate what they do.
