[None][infra] Add execution and test-runner skills for Claude Code - #17404
Conversation
WalkthroughThis PR adds local and remote execution skills, Slurm environment discovery, TRT-LLM test orchestration and reporting tools, and a performance optimization casebook with structured metadata and reference cases. ChangesExecution and testing workflow toolkit
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The new execution and test workflows can misreport failed jobs as successful, request incorrect resources, terminate unrelated containers, expose supplied credentials, or discard caller changes. These are concrete correctness, availability, security, and data-loss risks, so the PR is unsafe to merge until the major issues are fixed or explicitly accepted by the owners.

Restructure the .claude toolkit around a layered execution model and add a test-runner stack, so skills that need to run something delegate to a single executor instead of each embedding its own Slurm/Docker plumbing. Execution layer: - exec-env-check: probe GPUs, Docker, and Slurm access, return the execution scenario the callers branch on - exec-local-docker, exec-local-slurm, exec-remote-slurm: workflow-agnostic executors driven by a job_spec.json contract, with matching agents for the two Slurm variants - exec-slurm-compile: rename mount_dir to user_root_dir so the bind-mount parameter is not confused with container mount syntax Test-runner stack: - trtllm-test-specialist: classify module vs model tests, build commands, and delegate all execution to trtllm-case-executor - trtllm-case-executor and trtllm-test-script-builder: environment selection, script generation, and job submission - trtllm-test-specialist agent as the entry point Performance: - perf-optimization-casebook: 40 past optimizations recorded as decision precedents with machine-readable frontmatter, tag and pattern registries - perf-analysis and perf-optimization consult the casebook for prior art before recommending or routing an optimization Consolidation: - fold ad-sharding-ir-port into ad-model-onboard, which now covers the full sharding-aware IR porting procedure - drop trtllm-model-onboard-multimodal and the imported-kernel ABI checklist from trtllm-moe-develop Signed-off-by: Kaiyu Xie <26294424+kaiyux@users.noreply.github.com>
The previous commit consolidated four skills that are maintained upstream on GitHub and had not yet been synced into the toolkit checkout, so the consolidation was applied against a stale copy. Restore them to their upstream state; the consolidation should be redone after a sync. - ad-model-onboard: revert the folded-in sharding-aware IR porting section - ad-sharding-ir-port: restore, it remains a standalone skill - trtllm-model-onboard-multimodal: restore - trtllm-moe-develop: restore the imported-kernel ABI checklist Signed-off-by: Kaiyu Xie <26294424+kaiyux@users.noreply.github.com>

existing null sections to empty mappings before assignment. Avoid unconditional
setdefault calls so untouched sections remain absent, while preserving all
existing override behavior.
In @.claude/skills/trtllm-test-specialist/scripts/parse_config.py:
- Around line 190-205: Validate any provided test_type against functionality,
benchmark, and evaluation before applying scope defaults or determining required
keys; reject unsupported values such as bench with a clear error and exit.
Update the configuration parsing flow around the scope-default handling and
get_missing_required so invalid values cannot fall back to _REQUIRED_ALWAYS.

Nitpick comments:
In
@.claude/skills/trtllm-test-specialist/references/benchmark_config_template.yaml:
- Around line 124-127: Update the ctx role’s kv_cache_config to explicitly set
tokens_per_block to 32, matching the gen role and cp_config requirement; keep
the existing cache settings unchanged.
- Around line 98-102: Comment out the disabled load_balancer block in
moe_config, including num_slots: 0, matching the existing cp_config pattern;
leave it omitted from the active benchmark configuration so it aligns with
generate_benchmark_config.py behavior.
In @.claude/skills/trtllm-test-specialist/scripts/generate_benchmark_config.py:
- Around line 652-658: Add aggregated CLI aliases --cuda-graph-padding and
--cuda-graph-batch-sizes in the argument parser, mapping them to the existing
destinations args.gen_cuda_graph_padding and args.gen_cuda_graph_batch_sizes so
the aggregated builder’s CUDA graph configuration uses the same values without
changing its logic.
- Around line 336-364: Extract the duplicated MoE-backend and speculative MTP
override logic into a shared helper that accepts the target configuration and
relevant argument prefix/context. Replace the repeated implementations in the
gen, ctx, aggregated-server, and build_* configuration paths with this helper,
preserving each path’s existing override and removal behavior.
- Around line 590-598: The server_name override path currently applies changes
to every configuration when no matching entry exists. Update the no-target
branch near explicitly_set and args.server_name to exit with an error instead,
including the requested name and available server configuration names; do not
apply overrides to all server_configs.
- Around line 906-946: Refactor get_explicitly_set_args to stop reconstructing
parser actions via private argparse classes and internals. Create the parsing
path with public argparse APIs using argument_default=argparse.SUPPRESS, retain
the parser’s defaults separately, and apply those defaults after parsing so the
returned args and explicitly_set behavior remain unchanged.

Description
Restructures the
.claudetoolkit around a layered execution model and adds atest-runner stack. Previously every skill that needed to run something embedded
its own Slurm/Docker plumbing; now they delegate to a single executor through a
job_spec.jsoncontract.Execution layer
exec-env-check— probes GPUs, Docker, and Slurm access and returns theexecution scenario callers branch on.
exec-local-docker,exec-local-slurm,exec-remote-slurm— workflow-agnosticexecutors (pytest, eval, benchmark, and custom scripts are handled identically),
with matching agents for the two Slurm variants.
exec-slurm-compile— renames themount_dirparameter touser_root_dirsoit is not confused with container mount syntax.
Test-runner stack
trtllm-test-specialist— classifies module vs. model tests, builds thecommands, and delegates all execution to
trtllm-case-executor.trtllm-case-executorandtrtllm-test-script-builder— environment selection,script generation, and job submission.
trtllm-test-specialistagent as the entry point.Performance
perf-optimization-casebook— 40 past TensorRT-LLM optimizations recorded asdecision precedents (applicability signals, mechanism, expected effect,
accuracy risk, verification, rollback) with machine-readable frontmatter plus
tag and pattern registries.
perf-analysisandperf-optimizationnow consult the casebook for prior artbefore recommending or routing an optimization.
Consolidation
ad-sharding-ir-portis folded intoad-model-onboard, which now carries thefull sharding-aware IR porting procedure.
trtllm-model-onboard-multimodaland the imported-kernel ABI checklistfrom
trtllm-moe-develop.Documentation-only change: no library, build, or runtime code is touched.
Test Coverage
