Subject: [PATCH 01/63] feat(skills): find & diff user-modified bundled skills
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
`hermes update` keeps (won't overwrite) bundled skills the user edited
locally, but only printed a count — "~ N user-modified (kept)" — with no way
to learn which skills, or see what changed. Reverting already existed
(`hermes skills reset [--restore]`); discovery and inspection did not.
Add two CLI commands (zero model-tool footprint), reusing the manifest
origin-hash that sync already maintains:
- `hermes skills list-modified [--json]` — list the bundled skills whose
on-disk copy diverges from the last-synced origin hash (the exact test the
sync loop uses to decide what to skip).
- `hermes skills diff ` — unified diff between the user's copy and the
current bundled (stock) version, so the user can confirm what changed
before reverting.
Both are mirrored as `/skills list-modified` and `/skills diff`. The
`hermes update` notice now points at `hermes skills list-modified`. Core
helpers `list_user_modified_bundled_skills()` and `diff_bundled_skill()` live
in tools/skills_sync.py alongside the existing reset logic.

Subject: [PATCH 02/63] test(skills): cover list-modified + diff for bundled
skills
Exercises the real sync pipeline (no mocked comparison logic): a pristine
synced skill is not flagged; an edited one is listed and diffed (modified +
added files); an unknown skill returns not-ok; and `reset --restore` clears
the modified state so revert and discovery stay consistent.

Subject: [PATCH 03/63] fix(skills): surface list-modified hint on both update
paths + disambiguate diff
Salvage follow-up to the cherry-picked feat/test commits:
- W1: the unpack/install update path in main.py printed the
'~ N user-modified (kept)' notice without the new
'hermes skills list-modified' hint that the git-pull path got.
Mirror the hint to both sites so the count is actionable
regardless of which update path runs.
- W2: 'hermes skills diff ' (bundled-vs-stock) now shares the
verb with the gateway write-approval 'diff '. The gateway
handler's docstring + truncation message pointed users to
'/skills diff ' on the CLI, which now resolves a bundled skill
by that name instead. Point at the pending JSON file and note the
two diff commands are distinct.
- Add an invariant test asserting every 'user-modified (kept)' notice
in main.py carries the discovery hint (guards sibling drift).

Subject: [PATCH 06/63] test(langfuse): add end-to-end turn-isolation
regression
The PR added helper-level tests for _trace_key but nothing exercised the
keys through the real hooks. This adds TestTurnTraceIsolation, which drives
on_pre_llm_request / on_post_llm_call across two turns of one gateway
session (task_id == session_id, unique turn_id, api_call_count reset per
turn) and asserts each turn opens its own root trace when the first turn
fails to finalize (tool-only final step). This test fails on the pre-fix
code (only one trace opened, turn 2 absorbed into turn 1) and passes with
the scoping fix.
Also pins the turn_id-over-api_request_id key precedence: the turn-scoped
post_llm_call carries no api_request_id, so it must still resolve to the
same key as the request-scoped hooks or finalization breaks.

Subject: [PATCH 07/63] refactor(skills): dedupe file-listing, share
user-modified predicate, trim diff contract
Cleanup pass on the salvage (behavior-preserving):
- diff_bundled_skill now uses the existing _skill_file_list() helper
instead of reimplementing the rglob/is_file/relative_to file-set
enumeration inline (twice).
- Extract _is_tracked_user_modification(origin_hash, user_hash) and use
it in BOTH the sync loop and list_user_modified_bundled_skills() so the
'kept user edit' rule can't drift between the two sites.
- _read_text_for_diff -> _read_for_diff returns (bytes, text); the binary
branch now compares the bytes it already read instead of re-reading
both files from disk.
- Drop the unused 'user_present' key from diff_bundled_skill's return
contract (no consumer or test ever read it).
- test_update_modified_notice: drop the brittle '>= 2 sites' count-floor
so consolidating the two print paths into a shared helper stays a
welcome refactor; keep the per-site 'count notice => discovery hint'
invariant (still mutation-tested).

Subject: [PATCH 08/63] refactor(langfuse): extract _scope_prefix from
_trace_key
The turn- and api-scoped branches each repeated the same
task/session/thread fallback ladder with only the infix differing. Extract
the shared prefix into _scope_prefix so a future scope dimension touches one
ladder instead of three. The legacy branch still returns a bare task_id (not
the task: prefix) for backward compatibility, so it stays separate.
Output key strings are unchanged; a new test pins them across every
task/session/turn/api combination since the keys are matched across hooks
and any drift would silently break trace finalization.

Subject: [PATCH 09/63] fix(langfuse): bound _TRACE_STATE growth from
non-finalizing turns
Scoping the trace key by turn_id (the prior commit) fixed cross-turn
collisions but introduced a slow leak: _finish_trace only pops a key when a
turn ends cleanly (final response has content and no tool calls), so any
turn that is interrupted, ends on a tool call, or has empty final content
now leaves its uniquely-keyed entry in _TRACE_STATE forever. Previously the
constant per-session key was overwritten by the next turn, capping growth at
~1 entry per session.
Add an LRU cap (_MAX_TRACE_STATE) enforced by _evict_stale_locked, called
under _STATE_LOCK immediately before each insert. It evicts the
least-recently-updated entries (using the previously-dead last_updated_at
field) and ends their root span so nothing dangles. Regression test drives
50 non-finalizing turns against a cap of 8 and asserts the dict stays bounded
with the most-recent turns surviving.

The prior assertion `all("turn1" in k or "turn2" in k for k in keys)` was
weak on two counts: it passes vacuously when keys is empty (a regression
that lost all state would slip through), and after turn 2 finalizes only
turn 1 lingers, so it only ever inspected turn 1 anyway. Replace it with an
exact check that one key survives, it is turn 1, and turn 2 never merged
into it — the real isolation invariant the test name claims.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The Windows installer's Install-Uv spawned the astral uv installer with a
hardcoded bare `powershell -ExecutionPolicy ByPass -c "irm .../uv | iex"`.
That name resolves only to Windows PowerShell, and only when its System32
directory is on PATH. Run under PowerShell 7+ (`pwsh`) — or any session where
`powershell` isn't on PATH — the spawn dies with "The term 'powershell' is not
recognized", and uv installation aborts (the installer then appears stuck).
Add Get-PowerShellHostExe, which prefers the absolute path of the host we're
already running in (PATH-independent), then falls back to powershell/pwsh via
Get-Command, then to the bare name. Install-Uv now invokes that resolved exe.

Subject: [PATCH 16/63] fix(tui): MCP headline counts connected servers, not
disabled ones (#48402)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The TUI banner footer used the raw `info.mcp_servers.length`, so a
configured-but-disabled server (e.g. `linear`) was counted alongside
connected ones. With a disabled `linear` and a connected `nous-support`,
the TUI reported "2 MCP" while the classic CLI correctly reported "1 MCP"
(`mcp_connected = sum(1 for s in mcp_status if s["connected"])` in
hermes_cli/banner.py).
The collapse toggle even labels the count "connected", which was wrong
for the same reason.
Count connected servers for both the toggle and the footer segment, and
drop the `· N MCP` segment entirely when none are connected (matching the
classic banner, which only appends it when the count is > 0). The
expandable MCP section still lists every configured server, including
disabled ones.
Invariant test renders SessionPanel and asserts the headline equals the
connected count, never the configured total.

Subject: [PATCH 17/63] fix(tui): refresh tool snapshot when MCP discovery
lands after agent build (#48403)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The TUI banner reported fewer tools than the classic CLI for the same
config (e.g. 32 vs 38) when an MCP server connected slowly. Root cause:
the agent snapshots `agent.tools` once at build time and never re-reads
the registry. `_make_agent` briefly joins the background MCP discovery
thread (`wait_for_mcp_discovery`, ~0.75s) so fast servers land in that
snapshot, but a server slower than the bound — common for an HTTP MCP
server on first connect — lands *after* the agent is built. Its tools are
then absent from both the agent (uncallable until `/reload-mcp`) and the
banner for the whole session.
The classic CLI doesn't hit this because it re-derives
`get_tool_definitions()` at banner render time (which re-waits for
discovery), so it picks the late tools up.
Fix: after a fresh agent is built and its first `session.info` emitted,
if discovery is still in flight, schedule an off-critical-path daemon that
waits for it to finish, then rebuilds the tool snapshot and re-emits
`session.info` — the same rebuild `/reload-mcp` performs, but automatic.
Both the agent's callable tools and the banner count catch up.
Cache safety: the rebuild runs only while the session is still
pre-first-turn (`_user_turn_count`/`_api_call_count` both 0 → nothing
cached to invalidate). Once the user has sent a message we leave the
snapshot frozen rather than break the cached prompt prefix mid-conversation;
late tools then require an explicit `/reload-mcp` (user-consented), exactly
as today. No-op when discovery finished before the agent build, when the
join times out, when the registry was unchanged, or when the session was
swapped/closed while waiting.
Adds entry.mcp_discovery_in_flight() / join_mcp_discovery() accessors and
covers the matrix (added/none/post-turn/timeout/unchanged/replaced) with
unit tests.

+"""Tests for the TUI gateway's late MCP tool-snapshot refresh.
+
+When an MCP server connects slower than the bounded wait in ``_make_agent``,
+the agent is built without its tools and the banner/tool count is stale for the
+session. ``_schedule_mcp_late_refresh`` waits for discovery to land, then
+rebuilds the snapshot and re-emits ``session.info`` — but only while the

Subject: [PATCH 18/63] fix(desktop): dispose open PTY sessions in before-quit
handler
The `before-quit` handler tears down the bootstrap controller, preview
watchers, and the Python backend but never disposes live PTY sessions.
When `app.quit()` proceeds to `FreeEnvironment()`, node-pty's
`ThreadSafeFunction::CallJS` callback fires on a half-torn-down
environment, throws a C++ exception that can no longer be caught, and
the process aborts (microsoft/node-pty#904).
Iterate `terminalSessions` and call `disposeTerminalSession()` (which
already calls `pty.kill()` + deletes the map entry) before killing the
backend, so the ThreadSafeFunctions are removed before teardown begins.
Closes #48335

Subject: [PATCH 20/63] fix(nix): refresh npmDepsHash after the Electron
40.10.2 pin (#47792) (#48457)
PR #47792 pinned Electron to an exact 40.10.2 and regenerated the root
package-lock.json (dropping @electron/get@5 + @electron-internal/extract-zip,
restoring @electron/get@2 + extract-zip@2 + yauzl), but did not refresh the
shared npmDepsHash in nix/lib.nix. The hash still described the previous
40.10.3 lockfile, so npmConfigHook fails on every Nix build with
"npmDepsHash is out of date" for hermes-tui / hermes-web / hermes-desktop.
Regenerate the single shared hash to match the current lockfile.
Verified with fetchNpmDeps (authoritative, not prefetch-npm-deps):
nix build .#tui.npmDeps -> builds clean
nix build .#tui -> Validating consistency -> Installing dependencies
-> Finished npmConfigHook (no hash error)

Subject: [PATCH 21/63] fix(#37878): scrub operator environment before
launching cua-driver MCP
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
- Use _sanitize_subprocess_env() to filter Hermes-managed credentials
from the cua-driver subprocess environment (issue #37878)
- Prevents credential exfiltration to the third-party cua-driver binary
- Aligns with existing pattern used by browser-tool and other tools
- Add regression test to verify environment sanitization
The cua-driver is a lower-trust MCP subprocess per SECURITY.md §2.3.
Its inherited environment is now scrubbed by default, removing provider
API keys, gateway tokens, and platform credentials that should not leak
to third-party binaries.
Fixes #37878

Review feedback from egilewski:
1. Remove trailing whitespace from test docstring and mock patches (lines 1430, 1469, 1476, 1482)
2. Expand test coverage: also verify ANTHROPIC_API_KEY is stripped (not just OPENAI_API_KEY)
Changes:
- Remove trailing whitespace from test file
- Add ANTHROPIC_API_KEY to test environment
- Add assertion verifying ANTHROPIC_API_KEY is stripped from cua-driver subprocess env
- Syntax verified: python3 -m py_compile tests/tools/test_computer_use.py ✓

Subject: [PATCH 24/63] fix(skills): rmtree scope guard + default
pre_update_backup to true (#48200)
Defense-in-depth fix for the silent wipe of ~/.hermes/ documented in
#48200. A `hermes update --yes` run silently destroyed a user's
.env, MEMORY.md, kanban.db, custom skills, and scripts. Two changes:
1. `_rmtree_writable` in tools/skills_sync.py now refuses to rmtree
anything outside SKILLS_DIR (the HERMES_HOME/skills/ root).
All five call sites pass paths under SKILLS_DIR, so the guard is
a no-op for current code and a loud, recoverable failure for
any future regression (bad path join, malicious bundled
manifest, stale path in scope after an exception).
2. The default `updates.pre_update_backup` flips from false to
true in hermes_cli/config.py. A few minutes of zip per update
is negligible compared to silent total data loss. Still
overridable; --no-backup still works for one-off opt-out.
Five new tests in TestRmtreeWritableScopeGuard (root path,
hermes home, sibling dir, skills root itself, subdir) plus a
flipped `test_default_enabled_creates_backup` in test_backup.py.
178/178 tests pass in the two affected files. Public method
signatures unchanged, no test-stub blast radius.
Closes #48200

The salvaged guard allowed _rmtree_writable(SKILLS_DIR) itself. No call
site ever passes the root — every site passes a skill subdir or its .bak
sibling — so allowing the root only preserves the #48200 footgun (a dest
that collapses to the root wipes every installed skill). Require a strict
strict-child relationship and update the test that documented the
nonexistent 'full reset' capability.

Subject: [PATCH 26/63] fix(tui): don't make Enter swallow trailing-space-only
slash completions (#48425)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
* fix(tui): don't make Enter swallow trailing-space-only slash completions
Submitting a slash command in the TUI took three Enter presses: one to
complete the name (/ex → /exit), a second that only appended the trailing
space the gateway adds to keep the classic-CLI prompt_toolkit dropdown open
(/exit → "/exit "), and a third to actually submit.
The composer's submit handler accepted the highlighted completion whenever
applying it changed the input at all, so the whitespace-only delta ate an
extra keypress. Treat a completion whose only change is trailing whitespace
on an already-complete token as "already complete" and fall through to
submit. Partial-name and argument completions (a real token change) still
accept on Enter as before.
The replace/accept logic is extracted into pure helpers (applyCompletion,
completionToApplyOnSubmit) in domain/slash.ts.
* test(tui): cover Enter/completion trailing-space behavior and isolate poller queue
- completionApply.test.ts asserts completionToApplyOnSubmit accepts real
token completions (partial command name, argument) but returns null for a
trailing-space-only delta on an already-complete command, so Enter submits
instead of needing extra presses.
- test_notification_poller_delivers_completion / _skips_consumed previously
shared the process-global process_registry.completion_queue. Their events
carry no session_key, so a leaked/concurrent poller could dequeue and
dispatch them to a fixture agent without run_conversation, flaking CI
("AttributeError: '_FakeAgent' object has no attribute 'run_conversation'").
Isolate the queue per test (fresh queue.Queue via monkeypatch), matching the
sibling poller tests that already do this.

server
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Epic's experimental Unreal MCP plugin embeds an MCP server inside the
Unreal Editor process, served over local HTTP (127.0.0.1:8000/mcp by
default). HTTP transport, no auth, no install block — the user enables
the plugin in-editor and Hermes connects to the URL.
Also drops test_optional_mcps_manifests_ship_in_both_wheel_and_sdist:
it asserted wheel/sdist packaging targets for pip/Homebrew/Nix installs,
which Hermes does not support — installs run from the repo checkout, where
the catalog is discovered by directory iteration with no packaging step.

+ (the Toolset Registry dependency enables automatically).
+ 3. Edit > Editor Preferences > General > Model Context Protocol, turn on

Subject: [PATCH 28/63] feat(dashboard): surface full per-MCP catalog detail;
fix pip-install doc (#48520)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The dashboard MCP catalog only showed name/description/transport and a
non-clickable source. Users couldn't see what an entry connects to or runs
before installing — the exact detail the docs trust model tells them to vet.
- /api/mcp/catalog now returns transport target (url, or command+args),
auth_type, git install source/ref + bootstrap commands, default-enabled
tool hint, and post-install guidance per entry.
- McpPage renders the endpoint URL (http) or command+args (stdio), the git
install source/ref, a collapsible bootstrap-commands list, setup notes,
and the source as a clickable link when it's a URL.
- Docs: drop the 'uv pip install -e .[mcp]' quick-start step (Hermes does
not support pip installs; MCP ships with the standard install) and note
the dashboard now surfaces this detail.
- Strengthen the catalog endpoint test to assert the new inspection fields.

Subject: [PATCH 29/63] fix(install): fail fast when uv venv genuinely fails
under relaxed EAP
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
PR #48372 relaxes EAP=Stop around the uv venv call so PowerShell 5.1
doesn't mistake uv's 'Using CPython ...' stderr for a terminating
NativeCommandError. But relaxing EAP also means a *genuine* uv venv
failure (exit != 0) no longer aborts on its own — Install-Venv would
continue and print 'Virtual environment ready', and in stage mode
Invoke-Stage would report ok=true, even though no venv was created.
Capture $LASTEXITCODE immediately after the relaxed call and throw on
non-zero (Pop-Location first, matching the function's other exit paths),
so the venv stage fails fast instead of falsely succeeding. This is the
explicit guard originally proposed in #48463 (devorun), composed on top
of #48372's reusable helper + regression test.
Adds a regression test asserting the uv venv exit-code capture + throw.

Subject: [PATCH 30/63] feat(memory): batch operations for single-turn memory
updates (#48507)
The memory tool was strictly one-op-per-call. With the store running near
its char limit by design, a new add that would overflow gets rejected with
'consolidate now, then retry' -- but the model could not consolidate and add
in one call. It had to remove/replace across several turns, then retry the
add, each turn re-sending the whole conversation context. Expensive thrash.
Add an 'operations' array: a list of add/replace/remove ops applied
atomically against the FINAL char budget. The model frees space and adds new
entries in ONE call, even when an add alone would overflow. All-or-nothing:
any bad op aborts the whole batch, nothing written.
Root-cause note: the two agent-level memory interception sites
(agent_runtime_helpers.py, tool_executor.py) silently dropped any param not
in their explicit kwarg list, so 'operations' never reached the handler and
batch calls failed with 'Unknown action None'. Both now pass it through and
bridge each add/replace op to external memory providers.
Also: success response is now terminal (done=true + 'do not repeat' note,
no full-entries echo that invited re-edits); schema rewritten to lead with
the batch mechanism and an explicit one-shot stop rule (2138 -> 1476 chars).
Live-verified: near-full consolidate-and-add went 7 calls -> 1 call,
stable across 3 reps. 103 memory/approval tests + 398 background-review/
run_agent tests green; 6 new batch tests added.

Subject: [PATCH 31/63] fix(desktop): never persist or restore a named custom
provider as bare "custom" (#48547)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
* Port from cline/cline#11514: encourage parallel tool calls
Add a universal system-prompt guidance block telling the model to batch
independent tool calls (reads, searches, web fetches, read-only commands)
into a single assistant turn instead of one call per turn. The runtime
already executes independent batches concurrently (read-only tools always;
non-overlapping path-scoped file ops); the open-source system prompt had
nothing steering the model to PRODUCE the batch. Fewer round-trips means
less resent context, which compounds over a long conversation.
- prompt_builder.py: new PARALLEL_TOOL_CALL_GUIDANCE block (short, static,
cache-amortised) modeled on TASK_COMPLETION_GUIDANCE.
- system_prompt.py: inject right after the task-completion block, gated by
agent.valid_tool_names + the new toggle.
- agent_init.py: read agent.parallel_tool_call_guidance (default True).
- config.py: add the default under the agent section.
- test_prompt_builder.py: behavior-contract tests (batching steer, dependent
carve-out, length bound) — invariants, not wording snapshots.
Adapted from Cline's TypeScript tool-surface guidance to hermes-agent's
Python prompt-assembly architecture and config-over-env conventions.
* fix(desktop): never persist or restore a named custom provider as bare "custom"
Custom providers vanish from the Desktop/TUI model picker with
"No LLM provider configured" — repeatedly fixed (#44062, #44109, #45578)
and repeatedly regressed (#44022, #47714) because every fix only recovered
the entry identity from a persisted base_url. When a session is
persisted/restored with the resolved provider "custom" and NO base_url, bare
"custom" leaked through verbatim; resolve_runtime_provider("custom") routes to
the OpenRouter default URL with no api_key, so the next turn/resume dies.
Bare "custom" is the resolved billing class shared by every named providers:/
custom_providers: entry — it is not a routable identity. Centralize the
"never let bare custom escape" invariant in one helper,
runtime_provider.canonical_custom_identity(), and apply it at all four leak
sites in tui_gateway/server.py:
- _ensure_session_db_row — the ORIGIN: first DB write seeds the bad row
- _runtime_model_config — live persist
- _stored_session_runtime_overrides — resume restore (heals old rows; drops
unrecoverable bare custom so resume falls back to config default)
- _make_agent — rebuild / per-turn
The helper recovers custom: from the endpoint URL when present, else
from config.model.provider (the durable identity left when no base_url
survived). Regression tests in test_custom_provider_session_persistence.py
lock the no-base_url vector at every site so it cannot regress again.

Subject: [PATCH 32/63] fix(prompt): dedupe parallel-tool-call steer; correct
its rationale
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The universal PARALLEL_TOOL_CALL_GUIDANCE block already lives on main, but it
shipped with two rough edges this change cleans up:
- It duplicated the batching steer for Google models. The
GOOGLE_MODEL_OPERATIONAL_GUIDANCE block still carried its own
"Parallel tool calls" bullet, so Gemini/Gemma received the instruction
twice in one prompt. Drop the redundant bullet — the universal block is now
the single source.
- Its comment claimed "nothing in the open-source system prompt encouraged
batching," which was wrong: the steer existed for Google models only. Reword
to say the gap was that every *other* model got nothing.
- Tighten the test that asserts the steer (precedence-correct), and add an
invariant guarding against re-introducing the Google duplicate.

Subject: [PATCH 33/63] fix(desktop,tui): surface self-improvement review
summary + honor memory_notifications
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The "💾 Self-improvement review" summary (skill/memory updated) was invisible
on two surfaces:
- Desktop Electron app had no review.summary event handler — skill/memory
writes happened silently. Now appends a persistent system message to the
transcript (matching the Ink TUI's persistent-line semantics, not a
transient toast that can be missed).
- tui_gateway (backs both 'hermes --tui' and the desktop) never read
display.memory_notifications, so it always behaved as 'on' and ignored a
user who set 'off'/'verbose'. Added _load_memory_notifications() (mirrors
the messaging gateway's bool->str normalization, defaults to 'on') and
wired it to agent.memory_notifications, matching gateway/run.py and the CLI.
Delivery chain now reaches all surfaces:
background_review.py -> background_review_callback -> review.summary event ->
desktop transcript / Ink TUI line / gateway message / CLI print.

Subject: [PATCH 34/63] fix(dashboard): use DS Button prefix/size API instead
of inline icons
@nous-research/ui@0.18.2 Button is grid-based: size=xs is an
aspect-square icon-only box, and icons belong in prefix/suffix.
The dashboard used shadcn-style size=xs + inline text
children, which forced text buttons into broken tall squares
(Configure, Run setup, Select, Save keys) and split icon/label
across grid columns elsewhere (Schedule it, Prune/Delete actions).
Move leading icons to prefix and size text buttons as sm/default.
For the post-setup spinner, drive the spin from a button-level
[&_svg]:animate-spin selector since the prefix slot clones the
icon and overwrites its className.
- ToolsetConfigDrawer: Select, Save keys, Run setup
- SkillsPage: New skill, Configure
- AutomationBlueprints: Schedule it
- SessionsPage: Prune old sessions, Delete empty, Delete selected
