* feat(install): --no-skills flag for blank-slate default profile
Add an install-time --no-skills flag so the default ~/.hermes profile can
be created with zero bundled skills, matching what
`hermes profile create --no-skills` already does for named profiles.
The flag writes $HERMES_HOME/.no-bundled-skills and skips the install-time
seed. sync_skills() now honors that marker with an early return
(skipped_opt_out=True), so neither the installer, a later `hermes update`,
nor a direct sync re-injects bundled skills into a profile that opted out.
Previously the marker was only checked by seed_profile_skills() (named
profiles); the default profile had no opt-out and `hermes update` would
re-seed it every time.
Tests: TestNoBundledSkillsOptOut covers marker-present (no-op) and
marker-absent (normal seed) paths.
* feat(skills): hermes skills opt-out / opt-in for existing profiles
Adds an interactive counterpart to the install-time --no-skills flag so
an already-installed profile (default or named) can toggle the
.no-bundled-skills marker without reinstalling.
- `hermes skills opt-out` writes the marker (stop future seeding). Safe
by default: nothing on disk is touched.
- `hermes skills opt-out --remove` ALSO deletes already-present bundled
skills, but ONLY ones that are manifest-tracked AND byte-identical to
their origin hash. User-edited bundled skills, hub-installed skills, and
hand-written skills are never removed. Previews + confirms before
deleting (--yes to skip).
- `hermes skills opt-in [--sync]` removes the marker and optionally
re-seeds immediately.
Core logic lives in tools/skills_sync.py (set_bundled_skills_opt_out,
is_bundled_skills_opt_out, remove_pristine_bundled_skills) reusing the
existing manifest origin-hash machinery for the safety check.
Tests: TestOptOutToggleAndRemove covers marker toggle idempotency and
proves user-modified + non-bundled skills survive --remove.
* docs: blank-slate skills — install --no-skills + opt-out/opt-in
- features/skills.md: new 'Starting with a blank slate' section covering
the install flag, profile-create flag, and runtime opt-out/opt-in, with
a safe-by-default note.
- reference/cli-commands.md: document the new skills opt-out / opt-in
subcommands + examples.
- reference/profile-commands.md: fix the marker filename (was .no-skills,
actually .no-bundled-skills) and cross-link the runtime commands.
