Empty skill states say what is actually true

[wmadden-electric]

In a project whose installed Prisma packages ship no skills, prisma skills sync and prisma init reported "Agent skills are up to date." — vacuously true (zero stale copies) and misleading in exactly the situation a user runs the command to diagnose. Reported from the field against rc.9.

Presentation-only fix, operator-agreed wording. Every empty state now names itself, in precedence order: an empty configured agents list → "No agents are configured to sync skills for."; no allowlisted package installed → "No Prisma packages with agent skills are installed."; packages installed but none ship skills → "No Prisma dependencies in your project ship agent skills to sync." "Agent skills are up to date." now means only what it says. Mixed projects where any package ships skills keep today's behavior.

Init's skills.outcome gains distinct machine-readable values (no-agents / no-packages / no-skills) so scripts cannot read "installed and current" out of a vacuous success, and skills sync --json gains a skills array (the names the installed packages ship) so the distinction is visible there too. Exit codes unchanged, sync mechanics untouched, the per-command staleness check untouched (it was already correctly silent in these states).

Verification: 957 unit tests, credential-free e2e, conformance 0 failing / 6 pre-existing allowances, typecheck clean.

Summary by CodeRabbit

• New Features

  • prisma init now distinguishes between no configured agents, no eligible packages, and packages with no available skills.
  • Skills sync results list all skills shipped by installed packages, including unchanged skills.
  • JSON output reports clearer synchronization outcomes, including no-agents, no-packages, and no-skills.

• Bug Fixes

  • Improved status messages for empty, mixed, and prune-only skill configurations.
  • Corrected reporting when no eligible packages or skills are available.

• Documentation

  • Clarified skill synchronization states, messages, and JSON output conventions.

Walkthrough

The change adds distinct skill-sync outcomes for missing agents, packages, and skills. Synchronization now returns all skills shipped by installed packages. prisma init, skills sync, and skills list report separate empty states. Tests cover these states and mixed package sets. Documentation defines the new messages, JSON fields, and outcome values.

Merge Risk: 🟡 Moderate · up to 3122e

The new empty-state precedence can report a no-skills or no-packages condition after synchronization has completed, and may disagree with init’s machine-readable outcome. This creates a bounded correctness and scripting risk that should be resolved or explicitly accepted before merge.

- Around line 30-35: Update the sync summary logic around result.pruned,
result.packages, and result.skills so pruning is reported whenever entries were
removed, including when either collection is empty; align the classification
with prisma init’s “synced” handling. Add regression coverage for package
removal and package upgrades that remove skills.
