Inline comments:
In @.agents/skills/cuvslam-ci/reference.md:
- Line 8: Update the cuvslam-ci runner requirements documentation to explicitly
require host Python 3, since PR and nightly workflows invoke host python3 for
test-summary generation and release-asset validation; alternatively, move those
invocations into the cuvslam-ci:local image, but preserve the documented Docker
and GPU runtime requirements.
- Line 97: Update the cuvslam_benchmark_report.py metadata documentation to
describe every accepted release branch form: two-component and three-component
versions, each optionally carrying a suffix, while preserving the existing
metadata description.

In @.agents/skills/cuvslam-ci/SKILL.md:
- Line 106: Update the dataset gating guidance to distinguish PR evaluation and
staging, which must remain fork-gated with head.repo == github.repository, from
provisioning, which must be main-branch-gated because it receives write-capable
dataset credentials. Apply this clarification in
.agents/skills/cuvslam-ci/SKILL.md lines 106-106 and
.agents/skills/cuvslam-ci/reference.md lines 124-124, preserving the existing
safety constraint that fork code never runs on dataset runners.

In @.agents/skills/cuvslam-onboard/references/dataset-guides.md:
- Line 46: Align the dynamic-mask onboarding requirements by either raising its
documented Python minimum to 3.10 or replacing transformers==5.2.0 with a
release that supports Python 3.9; keep the dependency and minimum version
compatible.
- Around line 197-198: Update the EDEX example’s frame range to match its two
single-image sequence entries by setting frame_end to 1, preserving frame_start
at 1.

In @.agents/skills/cuvslam-onboard/references/live-cameras.md:
- Line 121: Update the DepthAI installation section near the run_stereo.py
reference to include a copy-paste command for installing the intended DepthAI v3
Python channel, and state the tested package version or link to the matching
Python installation instructions. Retain the udev rules setup guidance.

In @.agents/skills/cuvslam-onboard/SKILL.md:
- Around line 64-65: Update the cuvslam onboarding commands to use the
virtual-environment path selected by the user instead of hard-coding .venv, and
consistently reuse that path for activation, package installation, and example
execution.
- Around line 76-77: Apply a consistent shell-safe placeholder policy in both
.agents/skills/cuvslam-onboard/SKILL.md (lines 76-77) and
.agents/skills/cuvslam-onboard/references/dataset-guides.md (lines 151-152):
quote every user-provided path, host, dataset, ROS bag, EDEX, and
virtual-environment expansion as a single shell argument, including clone and
related commands, and avoid interpolating raw values into nested ssh commands.
- Around line 246-248: Update the command examples in the tools table for
tracker, cuvslam_api_launcher, and undistort to use the ./build/bin output path
produced by the CMake configuration, unless the documentation explicitly adds
the required build-directory or install step.

In @.agents/skills/cuvslam-trajectory/scripts/bootstrap_runtime.py:
- Around line 55-59: Update the CUDA directory discovery and selection logic
around directory_names so the canonical /usr/local/cuda symlink remains first,
while glob-discovered cuda-* directories are sorted by descending version before
matching. Ensure the fallback returns the highest available CUDA major
deterministically.

In @.agents/skills/cuvslam-trajectory/scripts/replay_dataset.py:
- Line 853: Move the KITTI writer import out of _write_kitti and perform it
during runtime loading or immediately after parsing when --output-format kitti
is selected. Catch import failures and raise ReplayError using the existing
_load_runtime bootstrap hint, while preserving the normal replay flow when KITTI
output is not requested.
- Line 992: Update the exception tuple in the replay failure handler to include
ImportError, covering lazy cuvslam_tools imports in _run_edex and _write_kitti
while preserving the existing “Replay failed” handling.
- Around line 832-833: Update the output formatting in the replay writer so the
converted timestamp is written with fixed nanosecond precision rather than
`.12g`, while retaining `.12g` formatting for translation and rotation pose
fields. Preserve strictly increasing timestamps for high-frequency data and the
existing TUM output layout.
- Around line 857-869: Update the KITTI validation in the replay output flow to
require exact frame coverage by rejecting results unless len(rows) equals
expected_frames, rather than accepting a fractional coverage value. Preserve the
existing row-shape and finite-value checks, and use the existing
save_poses_to_kitti_benchmark flow without changing other output formats.

In @.agents/skills/cuvslam-troubleshoot/commands/bag2edex.md:
- Around line 136-139: Align the bag2edex workflow on one canonical EDEX
filename: update the rosbag_extract_edex output or the tracker configuration so
both use the same name, preferably stereo.edex, and ensure the documented file
listing reflects that name.
- Around line 161-168: Update the patching flow containing the three str.replace
calls to verify that each replacement matched before invoking
p.write_text(text); fail if any replacement count is zero, and include the
package path and installed rosbags version in the failure report.

In @.agents/skills/cuvslam-troubleshoot/commands/debug-dump-patch.md:
- Around line 77-79: Update the Option B example invoking
patch_debug_dump_edex.py to use a source dump path that the host user can
traverse, or explicitly instruct users to run the workflow inside the container;
ensure every parent directory has read and execute permission so the output
images symlink can be followed.

In @.agents/skills/cuvslam-troubleshoot/commands/tracker.md:
- Around line 109-110: Update every worked example using CUVSLAM_OUTPUT to
create the configured output directory before tracking starts, preferably by
adding mkdir -p /tmp/out/ before the environment-variable command; apply this
consistently to all listed examples.

In @.agents/skills/cuvslam-troubleshoot/references/cuvslam-limitations.md:
- Around line 148-150: Update the description of max_frame_delta_s to identify
it as a timestamp-gap warning threshold based on consecutive frame timestamps,
not a pose-change or search-window bound. State that exceeding the configured
interval, including due to dropped frames, can degrade tracking.

In
@.agents/skills/cuvslam-troubleshoot/references/isaac-ros-visual-slam-usage.md:
- Line 109: Update the tracker usage guidance to document the required directory
layout and invocation: set CUVSLAM_DATASETS to the parent directory, then pass
the sequence with -edex and stereo.edex with -edex_filename. Remove the claim
that a debug-dump directory can be supplied directly, and reference the patch
script output if that is the established source of the exact command.
- Around line 45-52: The usage instructions reference a launch file that is not
installed with the external package; update the bag-playback command to invoke
scripts/isaac_ros_visual_slam_realsense_bag.launch.py via its repository path,
and ensure the sibling vo_pose_diff_recorder.py remains available alongside it.

In @.agents/skills/cuvslam-troubleshoot/scripts/inspect_rosbag.py:
- Line 195: Update the rectification check in the distortion-vector handling so
it recognizes any distortion vector whose coefficients are all zero, regardless
of length, including empty vectors. Replace the exact five-element comparison
while preserving the existing behavior for vectors containing nonzero
coefficients.
- Line 292: Update inspect to return its local ok status, returning False when
metadata.yaml is missing, and change the script entry point to pass
inspect(args.bag_folder, check_imu=args.vio) to sys.exit so missing required
topics produce a non-zero exit code.
- Line 173: Initialize cam_info_topics, topic_names, and info before the
metadata.yaml existence check, then guard the intrinsics and baseline processing
so it runs only when at least two camera_info topics are available. Update the
accesses in the reader filter and related logic, including the paths around
intrinsics and baseline handling, to avoid indexing missing topics and preserve
graceful behavior when metadata is absent or only one topic exists.
- Line 60: Update the rosbag2_py.StorageOptions construction in _open_reader to
pass an empty storage_id, allowing automatic plugin detection from metadata.yaml
while preserving the existing bag_folder URI.

In
@.agents/skills/cuvslam-troubleshoot/scripts/isaac_ros_visual_slam_realsense_bag_vio_throttled.launch.py:
- Around line 56-61: Update the warning block in the launch file to use a
module-scope import of launch.logging and obtain the logger through
launch.logging.get_logger('launch') instead of Python’s logging.getLogger. Emit
the same warning via lazy percent-style formatting, preserving the target_hz and
integration-interval details.

In @.agents/skills/cuvslam-troubleshoot/scripts/patch_debug_dump_edex.py:
- Around line 42-46: Update IMU_DEFAULTS to use the calibration keys consumed by
DatasetReader.get_imu_calibration: gyroscope_noise_density,
gyroscope_random_walk, accelerometer_noise_density, accelerometer_random_walk,
and frequency. Remove the unused gyro_noise_density, accel_noise_density, and g
entries, and provide defaults for every required noise field so the tracker
receives the intended sensor values.

In @.agents/skills/cuvslam-troubleshoot/scripts/stereo_image_throttle.py:
- Around line 126-128: Update the timer publishing logic around the retained
left/right images and their callbacks so it publishes only pairs whose
Image.header.stamp values match within a configured tolerance; otherwise retain
or discard unmatched messages until a valid stereo pair is available. Preserve
the existing publish flow for synchronized pairs.
- Line 98: Update the target_hz validation in the stereo throttling flow to
reject values less than or equal to zero before the warning branch and
timer-period calculation. Preserve the existing handling for positive
frequencies, including the target_hz below 60.0 warning behavior.

In @.agents/skills/cuvslam-troubleshoot/scripts/vo_pose_diff_recorder.py:
- Line 97: Update the default output handling in the pose-diff recorder so it
does not use the predictable shared path /tmp/vo_pose_diff.txt. Create the
default file atomically with a unique temporary name, or open it exclusively
with symlink protection, while preserving explicitly provided output paths and
the existing open(output_path, 'w') behavior where safe.

In @.agents/skills/cuvslam-troubleshoot/SKILL.md:
- Around line 105-110: Update the bag inspection instructions to add --vio when
the configured rig actually uses IMU data: retain tracking_mode: 1 and also
include configurations where Rig.imus is non-empty. Keep the VO command
unchanged for configurations meeting neither condition.
- Around line 194-195: Revise the slow-rate troubleshooting bullets to treat
improvement as evidence of a timing or throughput interaction, not proof that
calibration or data quality are uninvolved. Retain checks for CPU/GPU
utilization, frame processing, resolution, publish rate, throttling_time_ms,
data, calibration, and configuration; do not use slow-rate behavior as an
exclusion or stop condition.
- Line 18: Update both TROUBLESHOOTING.md references in the cuvslam
troubleshooting skill to use ../../../TROUBLESHOOTING.md, so they resolve to the
repository-root guide.

In @.agents/skills/README.md:
- Around line 58-61: Document a shared prerequisite before the Claude Code skill
installation commands: create ~/.claude/skills with mkdir -p before the blocks
in .agents/skills/README.md at lines 58-61 and 69-72 and AGENTS.md at lines
167-170; update the relevant installation instructions consistently, without
changing the copy or symlink commands.
- Around line 91-94: Update all four local skill paths in the OpenClaw install
commands to begin with "./", changing each ".agents/skills/..." reference to
"./.agents/skills/...".

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Make the CUDA directory fallback deterministic.

Path("/usr/local").glob("cuda-*") yields entries in filesystem order. If /usr/local/cuda is absent and both cuda-12.x and cuda-13.x are installed, the returned major version depends on directory order. The bootstrap then selects a wheel for an arbitrary CUDA major.

Sort the discovered directories and prefer the highest version. Keep the canonical symlink first.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Do not format the TUM timestamp with .12g.

timestamp is nanoseconds. After the division it is about 1.4e9 seconds for EuRoC, EDEX, and ROS bag data. .12g keeps 12 significant digits, so the written timestamp keeps only two decimal places, which is 10 ms resolution. Two effects follow:

  • The exported timestamps no longer match the source data, so ground-truth association in TUM tooling degrades.
  • For data above about 50 Hz, adjacent timestamps quantize to the same value. validate_tum rejects any non-increasing timestamp at line 63 of validate_tum.py, so the run fails after the full replay.

Format the timestamp with fixed nanosecond precision and keep .12g for the pose fields.

🐛 Proposed fix for timestamp precision
-                values = [timestamp / 1e9, *translation, *rotation]
-                stream.write(" ".join(f"{float(value):.12g}" for value in values) + "\n")
+                fields = [f"{timestamp / 1e9:.9f}"]

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Import the KITTI writer before the replay starts.

_write_kitti imports cuvslam_tools.tracker.kitti_benchmark only after the replay finished. If that module is missing or fails to import, the completed replay result is discarded and the operator must run the whole dataset again. _load_runtime already checks the runtime up front and returns an actionable message.

Resolve this import during runtime loading, or immediately after argument parsing when --output-format kitti is selected, and raise ReplayError with the bootstrap hint.

Require exact KITTI frame coverage.

save_poses_to_kitti_benchmark sorts frame IDs but skips missing or None poses. Therefore, output rows shift after a gap. Since replay_dataset.py validates only the coverage fraction, a 0.9 result can still contain misaligned rows. For --output-format kitti, require len(rows) == expected_frames or fill missing frames before writing.

_run_edex (line 678) and _write_kitti (line 853) import cuvslam_tools lazily. ImportError and ModuleNotFoundError are not in this tuple, so a missing tools package prints a raw traceback instead of the actionable "Replay failed" message that the rest of the script produces.

OpenClaw source-install.ts local path starts with ./ ../ ~/ absolute path

💡 Result:

In OpenClaw, the source-install.ts utility (located at src/skills/lifecycle/source-install.ts) handles the installation of skills from local directories and Git sources [1][2]. The logic to determine if a provided skill source string is a local path is implemented by checking if the string starts with specific prefixes, including absolute paths (/), current directory references (./), parent directory references (../), or the home directory shortcut (~/) [2][3]. This identification is typically performed by a helper function, often named isSkillSourceInstallSpec (or similar), which validates the input source format before proceeding with the install process [2][4]. Supported local path formats include: - Absolute paths starting with / [2][3] - Relative paths starting with ./ [3] - Parent-relative paths starting with ../ [3] - Home-directory-relative paths starting with ~/ [3] Technical details for these paths are enforced within the lifecycle/source-install subsystem to ensure security and proper resolution of the skill root during the installation phase [1][2][5].

This paragraph says that runners need only Docker and the GPU runtime, and that Python comes from cuvslam-ci:local. The current PR and nightly workflows invoke host python3 for test-summary generation and release-asset validation. A runner without host Python can therefore fail outside the CI image. Move these calls into the image, or document host Python as a runner requirement. (raw.githubusercontent.com)

_open_reader hardcodes storage_id='sqlite3', so it cannot select the mcap plugin for MCAP bags. The script supports Jazzy, where mcap is the default storage plugin. The read sections catch these failures and continue after printing errors. Pass storage_id='' so rosbag2_py detects the plugin from metadata.yaml.

🐛 Proposed fix
     reader.open(
-        rosbag2_py.StorageOptions(uri=bag_folder, storage_id='sqlite3'),
+        rosbag2_py.StorageOptions(uri=bag_folder, storage_id=''),
         rosbag2_py.ConverterOptions('', ''),

cam_info_topics is undefined when metadata.yaml is missing, and indexing it is unguarded.

cam_info_topics, topic_names, and info are assigned only inside the if meta_path.exists(): block at Line 120. The script explicitly supports a missing metadata.yaml (Line 86). On that path, Line 173 raises NameError, the broad except Exception at Line 225 swallows it, and the user sees Could not read camera_info: name 'cam_info_topics' is not defined. The whole intrinsics and baseline section is lost with a misleading message.

Line 201 has the same class of defect: cam_info_topics[1] is evaluated whenever intrinsics is non-empty. If the bag has exactly one camera_info topic (the [FAIL] path at Line 148 does not stop execution), this raises IndexError, again hidden by the broad handler. Line 190 has the same assumption for index 0.

Initialize the topic lists before the branch and skip the section when fewer than two camera_info topics exist.

Rectification check fails for distortion vectors that are not length 5.
