In `@CLAUDE.md`:
- Line 240: Add the missing "skin" subcommand to the two earlier
recognized-subcommand lists so the CLI auto-activation docs match the new
"qtmesh skin" feature; update the lists that enumerate recognized subcommands
(the sections before the detailed "qtmesh skin" description and the other
subcommand list) to include "skin" and ensure the sentence that explains CLI
mode activation ("CLI mode is activated by: (1) invoking via the `qtmesh`
symlink, (2) passing `--cli`, or (3) using a recognized subcommand as the first
argument.") remains accurate.

In `@qml/SkinWeightsDialog.qml`:
- Around line 81-178: InspectorButton and InspectorCheckbox are mouse-only; make
them keyboard-focusable and activate on Enter/Space. For InspectorButton (ids
btn and btnMa) set the interactive element (MouseArea) to be focusable (focus:
true and enableTabFocus / focusPolicy/Keys support), add Keys.onPressed handlers
to call btn.clicked() on Enter/Return/Space and update cursor/visual focus
styling when active; ensure the Text shows focus rect if needed. For
InspectorCheckbox (properties label/checked and its MouseArea + inner checkbox
Rectangle) make its MouseArea focusable the same way, add Keys.onPressed to
toggle parent.toggled() on Enter/Return/Space and update the displayed check
mark based on checked; ensure tab order / width behavior remains unchanged. Use
the existing ids (btn, btnMa, nf, ni, InspectorCheckbox, parent.toggled) to
locate and modify the components.

In `@src/CLIPipeline.cpp`:
- Around line 6951-6963: Filter the result of
Manager::getSingleton()->getEntities() to only real Ogre::Entity objects before
deciding failure/duplicate or performing a cast: after calling
MeshImporterExporter::importer(...) iterate the returned entities collection and
check each object's getMovableType() == "Entity", collect matching objects into
a new list (or vector) of Ogre::Entity*; then use that filtered list to test
emptiness, size>1 and to obtain the first Ogre::Entity* instead of using
entities.first(); this avoids miscounting ManualObject helpers and unsafe casts.
- Around line 6947-6983: Add Sentry breadcrumbs for the import and export steps
in the cmdSkin flow: before calling
MeshImporterExporter::importer({fi.absoluteFilePath()}) add
SentryReporter::addBreadcrumb(QStringLiteral("file.import"), QString("import
%1").arg(fi.absoluteFilePath())); and before calling
MeshImporterExporter::exporter(node, QFileInfo(outputPath).absoluteFilePath(),
fmt) add SentryReporter::addBreadcrumb(QStringLiteral("file.export"),
QString("export %1
fmt=%2").arg(QFileInfo(outputPath).absoluteFilePath()).arg(fmt)); keep using
SentryReporter::addBreadcrumb(category, message) and the same string
construction style as the existing ai.assist.skin_weights breadcrumb.

In `@src/MCPServer.cpp`:
- Around line 1490-1500: The arg parsing in toolComputeSkinWeights currently
trusts QJsonValue::toInt/toDouble/toBool which silently accepts wrong types;
update the parsing to explicitly validate types on args before assigning to
SkinWeightsOptions: for "max_influences" ensure
args["max_influences"].isDouble() and that the numeric value is integral (e.g.,
value.toDouble() == value.toInt()) before setting opts.maxInfluencesPerVertex,
for "falloff" and "max_distance" require args["..."].isDouble() before using
toDouble(), and for "skip_unweighted" and "replace_existing" require
args["..."].isBool() before using toBool(); on any type mismatch return an
explicit usage/error response from toolComputeSkinWeights instead of silently
using defaults.

In `@src/SkinWeights_test.cpp`:
- Around line 136-147: The test indexes low[1] and high[1] without first
asserting that the weight computations succeeded or produced at least two
elements; update the test around the two SkinWeights::computeWeights calls to
verify success and output size before accessing index 1 — for example, assert
the call returned a success status (if computeWeights has a return) or assert
low.size() >= 2 and high.size() >= 2 (or low.count/high.count where applicable)
after calling SkinWeights::computeWeights with kBarPositions, kTwoBones,
optsLow/optsHigh and before the ASSERT_GE/EXPECT_GE checks.

In `@src/SkinWeights.h`:
- Around line 65-69: The comment for the member skipUnweightedBones in
class/struct SkinWeights is inaccurate (it says "Default true" while the
initializer is false); update the comment to match the actual default (false) or
otherwise change the initializer if intended, e.g. edit the comment above
skipUnweightedBones to state "Default false" so the documentation matches the
initialized value skipUnweightedBones.

In `@src/SkinWeightsController.cpp`:
- Around line 115-120: When report.applied is false and report.error is empty
you emit the fallback "Skin weights failed" but never set result["error"],
causing callers (e.g., SkinWeightsDialog.runCompute) to see no error and replace
it with "unknown error"; update the failure path in SkinWeightsController (the
branch that checks report.applied and uses report.error) so that before emitting
the error signal you assign result["error"] = QStringLiteral("Skin weights
failed") when report.error.isEmpty(), ensuring the returned result contains the
same fallback string you emit.
- Around line 74-95: The code dereferences entities.first() and calls
entity->getName() and SkinWeights::computeAndApply without validating the
resolved entity; add a guard after obtaining Ogre::Entity* entity =
entities.first() to ensure entity is non-null (and its mesh if needed) and
handle the null/stale case by logging/reporting an error, clearing m_busy and
emitting busyChanged before returning or setting an error SkinWeightsReport;
reference the same null checks used by hasSkinnedSelection() and protect calls
to entity->getName() and SkinWeights::computeAndApply accordingly.

Inline comments:
In `@qml/PropertiesPanel.qml`:
- Around line 310-314: The CollapsibleSection for "Skinning" is incorrectly
gated by PropertiesPanelController.hasAnimations which hides the entire section
for skinned meshes without clips; change the sectionVisible predicate in the
CollapsibleSection so it does not require hasAnimations — either call
root.modeToolSectionVisible(EditorModeController.AnimationMode) alone or OR in
SkinWeightsController.hasSkinnedSelection so the section remains visible for
skinned selections while the SkinWeightsController.hasSkinnedSelection continues
to gate the button availability.
- Around line 1133-1164: The skinning button (Rectangle with id skinLabel and
MouseArea id skinMa) is currently mouse-only; make it keyboard accessible by
allowing focus on the MouseArea (set focus: true and focusPolicy: Qt.TabFocus),
add Accessible properties (e.g., Accessible.name = skinLabel.text and
Accessible.role = Accessible.Button) on the MouseArea or parent Rectangle, and
handle Enter/Space via Keys.onPressed (or Keys.onReleased) to call
root.openSkinWeightsDialog() just like onClicked; also ensure visual focus
indication (e.g., change border.color or opacity when skinMa.activeFocus is
true) and keep enabled binding to SkinWeightsController.hasSkinnedSelection so
keyboard users cannot activate when disabled.

In `@src/commands/ComputeSkinWeightsCommand.cpp`:
- Around line 21-27: Manager::getEntities() returns all movable objects so
iterating with Ogre::Entity* causes unsafe casts; change the loop to iterate as
Ogre::MovableObject* (or auto* as Ogre::MovableObject) from
Manager::getEntities(), check obj->getMovableType() == "Entity" before casting,
then cast to Ogre::Entity* (or use dynamic_cast) and compare its name to
mEntityName; update the loop in ComputeSkinWeightsCommand.cpp to perform the
movable-type guard prior to any Entity-specific access.

In `@src/SkinWeightsController.cpp`:
- Around line 77-98: The early-return branches in the method (checking !entity,
!entity->getMesh(), and missing skeleton via entity->getMesh()->getSkeleton())
bypass the single breadcrumb so failed attempts never reach Sentry; before these
validations run (or at least inside each early-return branch) call
SentryReporter::addBreadcrumb("ui.action", "<descriptive action>") so the UI
action is recorded, then emit the error and set
result["applied"]/result["error"] as currently done; update the
SkinWeightsController method containing these checks to add the breadcrumb using
category "ui.action" (or add one breadcrumb at the start of the validation
block) so every user-facing failure is recorded.

Outside diff comments:
In `@src/SkinWeights_test.cpp`:
- Around line 147-154: The test currently compares low[1]/high[1] which
correspond to the vertex at (0,1,0) that lies on bone 0 and masks falloff
differences; change the probe to a point off the bone (e.g. (0, 1.25, 0)) and
use the skinning result for that probe instead of low[1]/high[1], then assert
EXPECT_GE(highProbe.weights[0], lowProbe.weights[0]) (and keep the existing
count checks) so the sharper bind behavior is actually exercised; update any
variable names (e.g., create lowProbe/highProbe) or lookup logic to obtain the
entry for the (0,1.25,0) sample used in the test.

Duplicate comments:
In `@src/MCPServer.cpp`:
- Around line 1495-1496: The current check only ensures "max_influences" is
numeric but allows fractional numbers like 4.5; update validation around
args["max_influences"] in MCPServer.cpp to explicitly reject non-integral
numeric values by first checking isDouble() and then verifying that
args["max_influences"].toDouble() is an integer (e.g., compare to
std::floor/toInt-truncated value or use std::modf) before any later toInt()
call, returning makeErrorResult("Error: 'max_influences' must be an integer.")
if it’s not integral so the caller’s bad input is rejected rather than silently
falling back to a default.

Nitpick comments:
In `@src/commands/ComputeSkinWeightsCommand.h`:
- Around line 18-33: The comment block is outdated: it claims undo/redo do NOT
call _compileBoneAssignments(), but the implementation in restoreSnapshot()
does. Update the comment in ComputeSkinWeightsCommand to remove or correct the
sentence stating that the index maps are reinstalled without calling
_compileBoneAssignments, and instead document that restoreSnapshot() reinstalls
the index maps and also invokes _compileBoneAssignments() (and why, briefly) so
the comment matches the actual behavior of redo(), undo(), and
restoreSnapshot().
