[None][feat] Add perf-analyze and perf-optimize workflows to agent-flow - #18330
Conversation
Port two serving-performance workflows from upstream agent-flow, along with the core changes they build on, exposed as new `perf-analyze` and `perf-optimize` entry points. perf-analyze diagnoses a `trtllm-serve` deployment and changes nothing: it serves the checkpoint, benchmarks one operating point, derives an analytical speed-of-light ceiling, profiles the same load under nsys, the torch profiler and a bounded ncu per-kernel pass, and reports the single dominant bottleneck. The TensorRT-LLM checkout is read-only. perf-optimize is the applying counterpart. It reuses perf-analyze's task schema, prompt fragments, SOL projector and benchmark stages, then runs optimizer/evaluator rounds that apply the top-ranked roadmap item (serving config and/or source, on a dedicated git branch) and gate each attempt on measured gain against expectation, closing with a stateless QA re-measurement and a final report. Both resolve the SOL projector's methodology skill against the live session at launch: `internal-perf-sol-analysis` when present, otherwise `perf-analysis`, which grounds no peaks calculator and so yields a coarser ceiling. An unreachable probe assumes the full methodology rather than silently downgrading a stage the user asked for. Core changes carried over from upstream. The vendored agent_team and modeling_bringup workflows are left alone, as they hold changes that exist only in TensorRT-LLM so far. - `BackendClient.list_available_skills` reports which skills a session loaded. Both backends answer from the session the client already established (Claude Code from the CLI's initialize response, Codex from the `skills_list` its client issues at creation), so asking costs a process spawn and no tokens. `None` means the backend could not say, which callers must not read as "no skills are installed". - `AgentLayer.fetch_session_init` becomes `fetch_available_skills`, which answers the same question without sending a turn. `agent_flow.utils` gains `AgentSkillProbe.resolve` (matches a bare name against a loaded `<plugin>:<name>`) and `resolve_first_available_skill`, which fails open when no backend returns a usable list. - A failed Claude Code turn now reports the model, stop reason, usage and a bounded excerpt of any partial content. `AssistantMessage.error` is frequently the bare string "unknown", which told an operator nothing. - `AgentLayerConfig` gains `disallowed_tools`, so a layer whose input is untrusted can be kept away from `Bash` even though the backend runs with permissions bypassed, and `on_activity`, an observer for callers with no console to print to. Exceptions from the observer are swallowed, so it cannot fail the run it watches. - Bump claude-agent-sdk to 0.2.143 and openai-codex to 0.147.0, and add pytest's `--strict-config`. Without it, an environment missing pytest-asyncio downgrades `asyncio_mode` to a warning and then silently skips every async test. Three deviations from upstream, all because this repo is public and the service package is not vendored: - The operator skills are not ported: they hardcode one site's cluster, partition and image registry. The workflow READMEs and `task.example.yaml` are the operator guide here, and the tests that pinned the skills' contents were dropped with them. - The projector's hosted knowledge MCP server is not wired up, as its endpoint is site-specific. Its system prompt instead points at the `internal-glean-search` skill and `internal-glean-specialist` subagent, consulted only where the session has them, and the `--glean-mcp-url` flag and its environment variable are gone with it. Per workflow, one test pins that no role wires an external MCP server and one that the driving message stays clear of the route. - `test_the_census_matches_a_fully_populated_spec` asserted through `agent_flow.service.task_lint`, which is not vendored. It now runs the same census against the workflow's own `KNOWN_*` key sets, so it depends on nothing outside these packages. Signed-off-by: Kaiyu Xie <26294424+kaiyux@users.noreply.github.com>

WalkthroughThis change adds ChangesPerformance workflow platform
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to The PR adds performance analysis and optimization workflows, but the current implementation can accept incompatible profiling settings and trust coverage totals that do not match the profiled kernels, allowing misleading optimization gates and reports. Related baseline-selection and metric-normalization issues remain bounded but concrete, so merge should wait for these correctness issues to be fixed or explicitly accepted.

- Around line 187-202: Handle the case where include_disagg and kernel_coverage
are both enabled: either reject this combination during validation or
consistently support disaggregated kernel coverage by updating DISAGG_CAMPAIGN,
the coverage prompts, and analyzer ledger enforcement. Ensure the analyzer’s

successful empty skills_list response is preserved as [] rather than returned as
None. Distinguish the missing SessionInitEvent case from a known empty result,
while retaining None only when the skill state is genuinely unknown and

In `@agent-flow/agent_flow/layers.py`:
- Around line 383-386: In the ResultEvent branch of the client.send_message
loop, call the activity observer with the result event before assigning
result_text and usage, ensuring on_activity receives every backend event
including completion, usage, and result-error state.
In `@agent-flow/agent_flow/utils.py`:
- Around line 19-28: Update agent-flow/agent_flow/utils.py at lines 19-28,
38-67, and 122-171: convert AgentSkillProbe’s documentation to Google style with

and test Python modules, placing it before any module docstrings or imports
while preserving the existing implementation.
In `@agent-flow/agent_flow/workflows/perf_analyze/cli.py`:
- Line 1: Add the repository-standard NVIDIA copyright header, using the latest
meaningful modification year, to the new perf-analyze source and test files
identified in the review; also apply it to task.example.yaml if repository
policy treats that file as a source artifact. If the agent-flow package is
explicitly exempt, preserve that exemption instead of adding headers.
In `@agent-flow/agent_flow/workflows/perf_analyze/prompts/_common.py`:
- Around line 327-333: Update the num_gpus guidance in the shared prompt near
the serving world-size calculation to exclude moe_expert_parallel_size from the
product, matching the world-size rule that EP reuses TP ranks. Keep
tensor_parallel_size and pipeline_parallel_size as the multiplying factors, and
retain the requirement to cross-check against nvidia-smi and record the
determination beside the metrics.
In `@agent-flow/agent_flow/workflows/perf_optimize/disagg.py`:
- Around line 249-255: Update the profile reconciliation logic around profile
and notes so removing profile.kernel_coverage also appends a clear note when
that setting was supplied and dropped, matching the existing dropped
profile.methods and accuracy reporting; preserve the current removal and

In `@agent-flow/agent_flow/workflows/perf_optimize/README.md`:

perf-analyzeandperf-optimizeworkflows underagent-flow/.agent-flow/.QA Engineer Review
Test-code changes were added. No
tests/integration/test_lists/,test-db/,qa/, orwaives.txtupdates were provided.Added test coverage includes:
test_agent_layer.py.test_backends.py.test_examples.py.test_utils.py.perf-analyze.perf-optimize.The new test functions are not registered in
tests/integration/test_lists/based on the supplied changes.Verdict: needs follow-up.
Description
Ports two serving-performance workflows into the vendored
agent-flowpackage, exposed as newperf-analyzeandperf-optimizeentry points, along with the core changes they build on.perf-analyzediagnoses atrtllm-servedeployment and changes nothing. It serves the checkpoint, benchmarks one operating point, derives an analytical speed-of-light ceiling, profiles the same load under nsys, the torch profiler and a bounded ncu per-kernel pass, and reports the single dominant bottleneck. The TensorRT-LLM checkout is read-only for the whole run.perf-optimizeis the applying counterpart. It reusesperf-analyze's task schema, prompt fragments, SOL projector and benchmark stages, then runs optimizer/evaluator rounds that apply the top-ranked roadmap item (serving config and/or source, on a dedicated git branch) and gate each attempt on measured gain against expectation, closing with a stateless QA re-measurement and a final report.Both resolve the SOL projector's methodology skill against the live session at launch:
internal-perf-sol-analysiswhen present, otherwiseperf-analysis, which grounds no peaks calculator and so yields a coarser ceiling. An unreachable probe assumes the full methodology rather than silently downgrading a stage the user asked for.Core
agent_flowchangesThe vendored
agent_teamandmodeling_bringupworkflows are left alone, as they hold changes that exist only in TensorRT-LLM so far.BackendClient.list_available_skillsreports which skills a session loaded. Both backends answer from the session the client already established (Claude Code from the CLI's initialize response, Codex from theskills_listits client issues at creation), so asking costs a process spawn and no tokens.Nonemeans the backend could not say, which callers must not read as "no skills are installed".AgentLayer.fetch_session_initbecomesfetch_available_skills, which answers the same question without sending a turn.agent_flow.utilsgainsAgentSkillProbe.resolve(matches a bare name against a loaded<plugin>:<name>) andresolve_first_available_skill, which fails open when no backend returns a usable list.AssistantMessage.erroris frequently the bare string"unknown", which told an operator nothing.AgentLayerConfiggainsdisallowed_tools, so a layer whose input is untrusted can be kept away fromBasheven though the backend runs with permissions bypassed, andon_activity, an observer for callers with no console to print to. Exceptions from the observer are swallowed, so it cannot fail the run it watches.claude-agent-sdkto 0.2.143 andopenai-codexto 0.147.0, and adds pytest's--strict-config. Without it, an environment missingpytest-asynciodowngradesasyncio_modeto a warning and then silently skips every async test.Deviations from the source workflows
Three, all because this repository is public and the service package is not vendored here:
task.example.yamlare the operator guide here, and the tests that pinned the skills' contents were dropped with them.internal-glean-searchskill andinternal-glean-specialistsubagent, consulted only where the session has them, and the--glean-mcp-urlflag and its environment variable are gone with it.test_the_census_matches_a_fully_populated_specasserted throughagent_flow.service.task_lint, which is not vendored. It now runs the same census against the workflow's ownKNOWN_*key sets, so it depends on nothing outside these packages.This PR touches only
agent-flow/; no TensorRT-LLM runtime, kernel or API code is changed.Test Coverage
New unit tests, all offline (no GPU, no model weights, no network — backends and agent turns are stubbed):
agent-flow/tests/workflows/perf_analyze/— 189 tests acrosstest_task_schema.py,test_state.py,test_progress.py,test_prompts.py,test_sol_methodology.py,test_workflow.py.agent-flow/tests/workflows/perf_optimize/— 337 tests acrosstest_task_schema.py,test_roadmap_schema.py,test_state.py,test_progress.py,test_prompts.py,test_kernel_ledger.py,test_gitops.py,test_disagg.py,test_reuse.py,test_workflow.py.agent-flow/tests/test_utils.py— 12 tests forAgentSkillProbe.resolveandresolve_first_available_skill, including the fail-open path when no backend returns a usable list.agent-flow/tests/test_backends.py(list_available_skillson both backends, theNone"could not say" case, the richer failed-turn diagnostics),test_agent_layer.py(fetch_available_skills,disallowed_tools,on_activityincluding observer exceptions being swallowed),test_examples.pyandhelpers.py.Per workflow, one test pins that no role wires an external MCP server and one that the driving message stays clear of that route.
