Background

The repository ships eleven agent skills under plugins/trtmc-agent-skills/skills/,
two of which cover the most common contribution end to end — transform-model
for onboarding a Hugging Face model, debug-trt-mismatch for output that
disagrees with the reference. Nothing outside that directory named either of
them.

Verified across every entry point a reader or agent would start from:

for s in transform-model debug-trt-mismatch fp16-trt-network setup-trtmc-environment; do
  grep -rl -- "$s" --exclude-dir=node_modules --exclude-dir=.git . \
    | grep -v "^./plugins/trtmc-agent-skills/skills/$s/"
done
# transform-model and setup-trtmc-environment: no results at all.
# The other two: only sibling SKILL.md files and tests/tools/test_test_impact.py.

grep -c "skill" website/docs/extend/add-model-family.md   # 0
grep -n "AGENTS\|skill\|plugins/" CONTRIBUTING.md          # no matches
grep -in "skill" website/static/llms.txt                   # no matches
grep -c "transform-model" website/docs/agent-guide.md      # 0

The reference graph was closed: the skills cross-reference each other, but
nothing points into the directory, so a reader arrives only by listing it on
spec. AGENTS.md named the directory and routed exactly one skill
($write-git-messages), including the load-by-path fallback — both bullets
scoped to that one skill.

Concrete cost, from onboarding a family in #1123: roughly fifteen rounds of
whole-pipeline iteration on a numerical mismatch, when debug-trt-mismatch
opens by saying to bisect to the first divergent boundary instead. Separately,
three Community CPU failures on that PR — a complexity-ceiling violation, a C++
compile break, and a test-fixture OOM — were all reproducible locally by
commands the guides did not name.

Issue: #1125. A maintainer asked for the PR there, and asked that the
pre-merge/local test split in particular be made explicit.

Exit Criteria

  • A contributor or agent reaches the right skill from AGENTS.md, the AI &
    Agent Guide, or the add-a-family guide, without knowing the plugin directory
    exists.
  • The load-by-path fallback covers every skill, not one, so a runtime that
    lists none of them still finds them.
  • website/docs/extend/add-model-family.md states which jobs run in pre-merge
    and the local command that reproduces each.

Non-goals: no skill content is changed or duplicated, and the archived
website/docs/wiki/ pages stay archived — this adds no TensorRT internals
documentation.

Implementation

Three additive documentation edits, 80 insertions.

AGENTS.md — "Repo Skills". A task-to-skill routing table covering all
eleven, and the load-by-path fallback generalized from $write-git-messages to
any skill. It also states why that fallback matters: registration is through
the Codex plugin path, so other agent runtimes list none of these, and an empty
runtime skill list is not evidence that no skill covers the task.

website/docs/agent-guide.md. A "Repository skills" section naming the
directory, the read-by-path rule, and the two skills that cover the most common
contributions.

website/docs/extend/add-model-family.md — step 5. A table mapping each
Community CPU job to its local equivalent, taken from
.github/workflows/community-cpu.yml:

Pre-merge job Local
Source quality python3 -m tools.community_ci source-quality --base <base-ref>
Ownership and impact python3 -m tools.community_ci impact --base <base-ref>
Unit / C++ and Python python3 -m tools.community_ci unit --scope all
Docs cd website && npm ci && npm run test:model-support && npm run build

Plus the venv line for requirements/community-ci.txt, the note that
unit --scope all needs Docker and the others do not,
tools/test_impact.py --validate beside the existing model_ci.py validate,
the documentation site's checkpoint registration in
website/data/hf-model-metadata.json, the complexity ceiling of 10 for src/,
and one caveat that cost real time on #1123: a skipped test is not a passing
test, because pytest drops whatever importorskip cannot import, so run with
-rs and read which tests skipped rather than the count.

Change categories

  • Model or runtime behavior
  • Public API
  • ABI
  • Bundle or artifact format
  • Dependencies
  • Documentation only
  • CI or developer tooling

Validation

Commands and Results

Documentation reference check:

$ PYTHONPATH=python:. python3 tools/check_doc_file_references.py --strict website/docs
  Path references:      226
  Errors (phantom paths): 0
  Warnings (stale counts): 0
All checks passed.

The full Community CPU / Docs job:

$ cd website && npm ci && npm run test:model-support
# pass 4
# fail 0

$ npm run build
Verified 34 SVG diagrams.
[SUCCESS] Generated static files in "build".

The build matters here beyond the usual: both new sections contain
<name> and <base-ref> in inline code, and these pages are MDX. The build
confirms they are not parsed as JSX.

Community CPU / Source quality:

$ python3 -m tools.community_ci source-quality --base upstream/main
exit 0

Hardware, Environment, and Revisions

Repository head 328e984c, branched from upstream/main at 3b87adeb.
macOS 15, Python 3.12.10, Node 20.20.1, tools from
requirements/community-ci.txt. No GPU involved.

Not Run / Remaining Gaps

Community CPU / Unit / C++ and Python was not run locally: it builds the CI
container, and the local Docker daemon is arm64 while the job is amd64. This
change touches no source, so that job has nothing of this diff to compile; CI
runs it.

The wording of the new pre-merge table was derived by reading
.github/workflows/community-cpu.yml and tools/community_ci.py, and each
local command in it was run on #1123 where it reproduced the corresponding CI
job. It is not otherwise machine-checked, so it can drift if the workflow
changes.

Notes For Future Readers

The routing table is the part that has to stay current: a new skill added to
plugins/trtmc-agent-skills/skills/ will not appear in it automatically. If
that coupling is a concern, generating the table in doc-sync would be a
reasonable follow-up, and I am happy to do it in a separate PR.

Two items from the issue are deliberately not here. The optional TensorRT
network-definition footgun list belongs with fp16-trt-network and is a
different problem from routing, so it would be its own PR. The shared-runtime
ITrtModule::forward() output-lifetime contract is #1126.

Risk level

  • Low
  • Medium
  • High

Documentation only. No source, tests, workflows, or generated data change; the
three edits are additive, and the documentation build and reference checker
both pass.

The repository ships eleven skills under plugins/trtmc-agent-skills/skills/,
two of which cover the most common contribution end to end, but nothing outside
that directory named them: not AGENTS.md, CONTRIBUTING.md, the AI & Agent
Guide, llms.txt, or the add-a-family guide. The reference graph was closed, so
a reader reached them only by listing the directory.

AGENTS.md now carries a task-to-skill routing table, and the load-by-path
fallback applies to every skill rather than only $write-git-messages. That
matters for non-Codex runtimes: registration is through the Codex plugin path,
so those runtimes list none of these, and an empty runtime skill list reads as
"no skill covers this".

The agent guide, which exists to orient agents, now names the directory and the
two skills that cover onboarding and reference mismatches.

The add-a-family guide gains the part contributors cannot infer: which jobs run
in pre-merge, and the local command that reproduces each. It also names
tools/test_impact.py --validate beside model_ci.py validate, the documentation
site's checkpoint registration, the complexity ceiling for src/, and the reason
a green pytest summary can still be missing coverage -- a skipped test is not a
passing test.

Closes NVIDIA#1125

In `@website/docs/extend/add-model-family.md`:
- Around line 295-296: Update the documentation paragraph describing `unit
--scope all` to state that it requires a Docker daemon capable of running the
`linux/amd64` platform, either natively or through emulation, because CI targets
amd64; note that arm64-only hosts without this setup may fail or produce
different results.
- Around line 291-293: Update the CI setup instructions following the .venv-ci
installation to activate that virtual environment before the documented gates
run, or consistently invoke the installed Python and tooling through
.venv-ci/bin; ensure all listed commands use the environment containing
requirements/community-ci.txt.
- Line 282: Update the Community CPU / Source quality row so it clearly states
that cyclomatic complexity is checked across the entire src/ tree, while ruff
and clang-format apply only to changed files; keep the model architecture
contract coverage unchanged.

Three corrections from review, each of which the previous text got wrong in a
way that would have cost a reader a failed run.

The complexity check is not a changed-file check. `ruff` and `clang-format`
look at the diff; the `src/` ceiling is evaluated across the whole tree, so a
change can be rejected for a function it did not touch. The table said "on
changed files" in a position that covered all three.

The virtual environment has to be activated, not addressed. The gates shell out
to `lizard`, `ruff` and `clang-format` by name and one check invokes bare
`python`, so installing into `.venv-ci` and then running the system `python3`
leaves the tools unresolvable.

`unit --scope all` needs two things the text did not mention. It refuses to
start unless its scratch sits under `RUNNER_TEMP`, which is set on a runner and
not locally. Its image is built without `--platform`, so it follows the Docker
host while pre-merge runs `linux/amd64`.

Also records what a local container run costs in accuracy: on macOS an
unmodified tree reported four failures a Linux runner does not, all from
permission and locking semantics the bind mount does not carry. Checking a
failure against the base branch before chasing it is the part worth having
written down.
