Estimated code review effort: 2 (Simple) | ~15 minutes Merge Risk: 🟡 Moderate · up to This PR adds operator instructions for performance campaigns, but a documented failure path can repeatedly resubmit jobs indefinitely, consuming cluster capacity and preventing completion. It also retains several bounded documentation and repository-compliance issues, so the PR is not merge-ready until the resubmission behavior is fixed or explicitly accepted.

- Line 3: Update the skill description near the workflow summary to clarify that
nsys, torch-profiler, and ncu profiling runs by default or when enabled through
profile.methods, rather than implying every run always uses all three. Keep the
existing default-all-three behavior and configuration semantics unchanged.
- Line 1: Add the repository-standard NVIDIA copyright header to the Markdown
file, using 2026 and placing it so the existing YAML frontmatter remains valid.
- Around line 72-73: Update the preflight instruction in the skill text for
login or head nodes with no local GPUs to remove the nonexistent
Environment-section reference; instead, link an existing generic setup guide or
explicitly state that environment setup is outside this skill’s scope.
- Line 78: In the multi-rank coverage sentence, replace “serves” with “servers”
so the phrase reads clearly as “on multi-rank servers expect.”
In `@agent-flow/.claude/skills/perf-optimize/SKILL.md`:
- Line 3: The perf-optimize workflow description and related cost, wrap-up, and
reporting sections should make final-verification claims conditional on at least
one optimization item being accepted. Align these statements with the QA
contract: when no item is accepted, explicitly report that final verification
was skipped and do not promise a verified final measurement.
- Around line 1-3: Add focused tests for the perf-optimize skill covering skill
availability, launch instructions, and safety guidance in its operator contract.
Follow the existing agent-flow skill-test conventions and run the repository’s
pre-commit checks and full test suite to verify the changes.

The perf-analyze and perf-optimize workflows were vendored into agent-flow/ without the two operator skills that teach Claude Code to reach for them. An agent asked to diagnose or optimize a trtllm-serve deployment therefore hand-rolls a serve/benchmark/profile loop and the vendored workflows go unused. The skills were held back because their SKILL.md hardcoded one site's login node, Slurm partition and container registry, which does not belong in this repository. Port both, minus that environment setup section. Allocating a GPU node, launching the container and building the wheel are cluster-specific steps an operator already has a recipe for, and no wording of them generalizes across sites. What the skills keep is what is specific to driving these two workflows -- the preflight checks, the stage-by-stage contract, how to read the resulting report, and how a run resumes after its allocation expires. Also point the preflight install hint at the copy of agent-flow that ships in the checkout, and refresh the perf_optimize README note that still said the skill was not vendored here.

- Around line 12-13: Update the `trtllm-serve` pipeline summary in `SKILL.md` to
state that it benchmarks one operating point or a Pareto curve, reflecting that
`benchmark.concurrency` may be a non-empty list and triggers one benchmark per
point.
In `@agent-flow/.claude/skills/perf-optimize/SKILL.md`:
- Around line 331-334: Update the launch-host keeper workflow to persistently
track resubmission attempts, enforce a configurable retry limit, and apply
increasing backoff before resubmitting checkpoints with done: false. Add an
explicit operator reset mechanism that clears the retry state, while preserving
the distinction between terminal failures and resumable checkpoints; do not
treat process termination as done: true.

Description
Follow-up to #18330, which vendored the
perf-analyzeandperf-optimizeworkflows but deliberately held back the two operator skills that go with
them:
Without them, an agent asked to diagnose or optimize a
trtllm-servedeployment hand-rolls its own serve → benchmark → profile loop and the
vendored workflows go unused — the skill
descriptionis what makes ClaudeCode reach for the workflow in the first place.
This ports both skills, minus the environment setup section that was the
reason to hold them back. Allocating a GPU node, launching the container and
building the wheel are cluster-specific steps an operator already has a
recipe for, and no wording of them generalizes across sites — so rather than
shipping a
<placeholder>template nobody can run as written, that sectionis simply dropped. What each skill keeps is what is specific to driving its
workflow:
(
perf-optimizeneeds a clean checkout and a branch;perf-analyzeisread-only with respect to the TRT-LLM checkout).
task.yaml— every field, which are required, and thedefaults. Including the per-measurement cost estimate that is the Bump onnx from 1.12.0 to 1.13.0 #1
launch trap for
perf-optimize: a measurement that cannot finish insideone allocation restarts forever and the campaign never completes.
what the progress output means, and which artifacts to point the user at.
resumes from its own
.perf_{analyze,optimize}_state.json), and thatpartition-level
DenyQos— not the QoS list on your account — is whatusually decides the walltime ceiling.
Also updates two things the port makes stale:
perf-optimizeREADME note still said the skill was "not vendoredhere"; it now links to it and states what it does and does not cover.
<trtllm_repo_path>/agent-flow—the copy in the checkout being tested — rather than upstream agent-flow,
so an operator cannot end up running stale workflow code against these
instructions.
Markdown only, all of it under
agent-flow/. No TensorRT-LLM runtime,kernel, API or Python code is changed.
Test Coverage
No new code paths, so no new tests — both files are operator documentation
consumed by Claude Code, and
agent-flow/tests/pins no skill contents(the tests that did were dropped alongside the skills in #18330).
Verified that the existing suite is unaffected:
Also checked by hand that the port left no dangling references: the state
filename in each skill matches its workflow's
state.pySTATE_FILENAME,and no section removed with the environment steps is still cross-referenced.
