Adds a one-time, idempotent startup migration that moves every user Rule
out of the `PromptStore` LMDB database into the new Skills + AGENTS.md
world, in a single pass:
- **Non-Default Rules → global Skills.** Each one becomes
`~/.agents/skills/<slug>/SKILL.md` with `disable-model-invocation:
true`, preserving the original behavior that non-Default Rules were only
ever invoked when the user named them. They're now invokable via
`/skill-name` (and still `@`-mentions).
- **Default Rules → global AGENTS.md.** Each one is appended to
`paths::agents_file()` (e.g. `~/.config/zed/AGENTS.md` on macOS/Linux,
`%APPDATA%\Zed\AGENTS.md` on Windows) under an `## H2` heading
containing the rule's title. Default Rules used to be auto-included in
every conversation; the global AGENTS.md is loaded into the system
prompt of every conversation, so the behavior is preserved.
- **Customized built-in prompts → global AGENTS.md** (currently just the
commit-message prompt). If the user has edited a built-in away from
Zed's shipped `default_content()`, the edited body is appended at the
top of the AGENTS.md block. Uncustomized built-ins (still on the shipped
default) are skipped so we don't pollute AGENTS.md with text the user
never wrote.
The migration is gated on the `skills` feature flag — users without the
flag never have their Rules touched in any way. A single global KVP flag
(`rules_to_skills_migration_done`) short-circuits the migration on
subsequent launches, so it runs at most once per machine even across
release channels. A process-lifetime `AtomicBool` guard additionally
prevents racing duplicate spawns when the underlying `cx.on_flags_ready`
callback fires multiple times at startup.
Migration is intentionally non-destructive: rule rows in the LMDB
database stay in place. Users can still see and edit them through the
existing UI, and a downgrade to a Zed build without skills support won't
lose anything.
Slug generation (`agent_skills::slugify_skill_name`) lowercases ASCII
letters, turns spaces into dashes, and drops every other
non-alphanumeric character entirely — so `foo!bar` becomes `foobar`, not
`foo-bar`. `&` is special-cased to become `and` (so `rock&roll` →
`rock-and-roll`). Slug collisions and pre-existing skill directories are
handled by appending `-2`, `-3`, etc.
A title-bar onboarding banner ("Skills have replaced Rules") surfaces
for every user on the `skills` feature flag. Clicking it opens a small
`AlertModal`-based explainer that summarizes the two destinations and
points users at the new `/skill-name` slash command (and notes that
`@`-mentions still work).
