Overview

The root AGENTS.md mixed developer guidance with optimization-loop operating rules, PR policy, and docs rules, so an agent working on Dynamo code had to read past about 120 lines that didn't apply. This PR focuses the file on development: where things are in the repo, which skill handles a task, and how to build and test efficiently, including where to get nightly images and wheels instead of building them.

Key Changes

Docs only; 0 lines of core logic.

• AGENTS.md: adds vLLM, SGLang, TensorRT-LLM, and TokenSpeed to the ecosystem section and regroups the skills index by task. Points to README.md for the overview. Adds a Build and Test section: published nightly artifacts, setup prerequisites, the local-dev container, a Rust edit loop with measured build costs, and targeted pytest runs. Removes the optimization-loop operating rules and replaces the PR, docs, and agent-file rules with pointers to pr-checklist, CONTRIBUTING.md, and the docs skills.

Validation

Every command in Build and Test was run in a clean worktree on a 24-core Ubuntu 22.04 workstation (rustc 1.96.1), except where noted.

Command	Result
Rust edit loop: check, --lib scheduling::, --test http-service, --lib, all targets, fmt, clippy	All pass; times in the table are from this run
Sidecar -p set; -p set switching; RUSTFLAGS and CARGO_PROFILE_DEV_DEBUG changes	New set or flag = rebuild; line-tables-only cold build 4 min vs 5.5 min full
Feature lanes: --no-default-features, standalone-indexer, nvtx, --profile profiling	All build
Python dev build in a fresh venv, dynamo.frontend --help	Works; protoc 3.12 (Ubuntu 22.04 apt) fails relay.proto, hence the protoc note
maturin develop default features vs CI features, then router tests	Default: 2 of 8 test_router_decisions fail (no kv-indexer); CI features: 9 of 9 pass
Test ID and -k pytest examples	Pass
Nightly wheels and image tags	Resolved on pypi.nvidia.com and nvcr.io; docker run --rm <image> pip show <engine> checked on a local nightly
Skills index, AGENTS.md/CLAUDE.md pairs, relative links	validate_skills.py, validate_agent_instructions.py, link check

Not run: the local-dev docker build and run.sh (only render.py), the GPU tests/serve example, and the macOS note.

Issues and Ongoing Work

• Closes DGH-2291
• docs: add tier-specific agent guides #13439 (tier-specific agent guides, closes docs: add tier-specific agent guides #16469) adds a "Component Guides" section to the root AGENTS.md and will conflict with this PR. The two are complementary; whichever merges second rebases.
• docs(router): add a kv_router README and expand its agent guide #17350 splits lib/llm/src/kv_router docs into README.md and AGENTS.md; no overlap.

Walkthrough

The root agent guide now provides a repository map, categorized skill references, and expanded build, test, lint, and pull-request instructions. The optimization guide adds procedures for long-running runs and skill-pack issue reports. A workload skill now links to that guide.

Changes

Agent guidance

Layer / File(s)	Summary
Repository map and skill catalog AGENTS.md	The root guide adds a repository map and ecosystem table, lists TokenSpeed, and reorganizes skill references by task.
Build, test, and pull-request guidance AGENTS.md	The guide adds Python, container, and Rust build guidance; targeted test and lint commands; and references to pr-checklist and CONTRIBUTING.md.
Long-running runs and issue reporting agent-docs/guides/optimization/optimize-loop.md, .agents/skills/synthesize-user-workload/SKILL.md	The optimization guide describes harness-aware polling, goal-mode use, unattended-run constraints, and skill-pack issue reporting. The workload skill links its long-running-run handoff to the guide.

Priority: Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: Low · up to 9cd52

Test guidance can lead CPU-only contributors into GPU-dependent or model-downloading tests. Correct the selections and pytest examples; these documentation issues are bounded and do not block a merge if the owner accepts a follow-up.

Full details: Out of Scope Changes check

Explanation

All changes fall within the PR's stated docs-focus objective. The root AGENTS.md rewrite adds ecosystem entries (including TokenSpeed), regroups the skills index, adds a Build and Test section, and replaces PR, docs, and agent-file rules with pointers. The optimize-loop.md diff adds the "Long-Running Runs And Harness Compatibility" and "Improving These Instructions" sections, which the PR description says were moved from the root guide. The diff shows only additions in optimize-loop.md (+52/-0). The synthesize-user-workload SKILL.md change updates one reference to the moved guidance. No unrelated source or logic changes were observed in the reviewed files. The verbatim-move claim was not compared line by line against the base AGENTS.md, but this does not affect the scope verdict.

Full details: Linked Issues check

Explanation

Issue #16469 is open and directly linked, so its acceptance criteria apply to this PR. The PR objectives call it background only because it says "Implemented by PR #13439." That text does not change the issue state. A reference to another PR is not evidence of code in this PR. Unmet criteria at head: (1) The root guide does not point to tier guides. The head AGENTS.md has no links to Rust workspace, runtime, Python, or Kubernetes guides, and it has no component-guide section. (2) No tier guides are added. The changed files are AGENTS.md, agent-docs/guides/optimization/optimize-loop.md, and .agents/skills/synthesize-user-workload/SKILL.md. The agent-docs tree at head holds no tier guides. (3) No CLAUDE.md import siblings or ownership routing are added for tier guides. (4) The guide-level criteria (source layout, local conventions) cannot be met because no guides exist. The PR description states that #13439 owns this work. That is a deferral, not a fulfilment at this head.

Resolution

Add tier-specific AGENTS.md guides for the Rust workspace, runtime crate, Python components, and Kubernetes deployment. Each guide must describe its source layout, local development conventions, and links to canonical architecture docs. Add the required CLAUDE.md sibling for each guide per repository policy. Add ownership routing for each tier. Link each guide from the root AGENTS.md. Alternatively, if #13439 is to satisfy #16469, record that decision on the issue and link #13439 as the implementing change. Compliance for this PR is still not established until that work is present at the reviewed head.

Review comments at @agent-docs/guides/optimization/optimize-loop.md:
- Around line 95-96: Update the documentation wording in the sentence about
filing issues so it allows comments on any approved issues, not only duplicates.
Replace “comments on duplicates” with wording that covers any approved comments
while preserving the surrounding batching and issue limits.

Review comments at @AGENTS.md:
- Around line 230-243: Update the Python test command examples in the test
guidance section to invoke pytest through `python3 -m pytest` instead of bare
`pytest`, including collection, marker-based, targeted, and end-to-end examples;
leave the commands’ arguments unchanged.
- Around line 233-235: Update both pytest commands in the “No GPU” section to
include the gpu_0 marker in their selection expressions, limiting the unit and
integration runs to tests marked for GPU 0.
- Line 234: Update the section label above the `pytest -m "integration and
pre_merge"` command so it describes the broader integration selection, not just
tests against dynamo.mocker workers. Note that the unified canary starts NATS
and etcd on dynamic ports and downloads Qwen/Qwen3-0.6B unless `--models-dir` is
set; it requires `huggingface_hub` and may fail if the download or server
startup fails.

Previously reported defects still present:

• Original discussion: The Python examples still use bare pytest, although the repository's pytest contract requires python3 -m pytest; in the documented venv workflow, the system pytest can run outside the venv and fail to import venv-installed packages such as dynamo.
• Original discussion: The commands labeled “No GPU” still select every unit and pre_merge or integration and pre_merge test without requiring the gpu_0 hardware marker, so they can collect tests that start a real engine and require CUDA. Add and gpu_0 to both selectors.
• Original discussion: The integration command is still described as mocker-only, but its selection includes the unified canary, which starts NATS and etcd and downloads Qwen/Qwen3-0.6B unless --models-dir is supplied. Document those prerequisites so users do not treat the command as a hermetic mock-only run.

One P2 finding in the optimization handoff instructions.

Seems reasonable to me other than the one agent finding above
