and _match_local_models to catch the failures raised by their helper calls,
including RuntimeError, ValueError, and ResponseTooLarge where applicable, and
wrap them in TemplateCheckError so check_cmd continues returning structured
error envelopes. Map ResponseTooLarge from _list_local_folder to the
model_listing_too_large error.

… --check-local` (BE-8974) `available_locally` on a knowledge pick never looked at model files, so the best oss pick for a capability could be one whose weights are not on this machine. `comfy templates check` already answers that per template, and every pick names its template. `knowledge pick --check-local` runs that check on each oss pick. A pick with missing files gets `available_locally: false`, an `unavailable_reason` and a `missing_models` count. A template absent from the gallery is flagged too. `local_check` says whether the check ran. When the server is down, the gallery cannot load or a folder listing is over the size cap, it carries that code and nothing is flagged. Off by default because it fetches uncached workflows and calls the local server. missing_models is a count because pick envelopes are kept under the 4096 bytes the cloud agent passes through unchanged. With every oss pick flagged, the largest capability under that cap grows from 3650 to 4095 bytes. image-edit was already over at 4272 before this change. The gallery lookup, workflow fetch and folder matching move out of check_cmd into helpers both commands call. templates check output is unchanged. The pick check loads the gallery without stale-while-revalidate, like show and fetch, so a stale index cannot flag a new template. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
A pick whose template workflow could not be fetched or parsed, whose template declares no models but loads them, or whose template is missing from a gallery index that could not be confirmed fresh now carries its own `local_check` instead of reading as verified runnable. A pick whose missing files all sit in a folder the local server does not have gets its own `unavailable_reason`. `_gallery_rows`, `_template_workflow` and `_match_local_models` now raise `TemplateCheckError` for non-200 responses, over-cap bodies and deep JSON nesting, so `comfy templates check` returns an envelope instead of a traceback. An over-cap folder listing maps to `server_not_running`, as in `comfy models list-folder`. The folder name is validated with `_is_walkable_folder_name` and percent-encoded, and `templates check` refreshes a stale gallery index before its exact-name lookup.

In `@CHANGELOG.md`:
- Around line 36-39: Update the changelog text describing _check_picks_locally
to state that missing templates receive the template_not_found local_check and
are marked available_locally: false only when the gallery lookup is fresh; stale
or failed gallery refreshes must not flag templates as missing.
In `@comfy_cli/command/templates.py`:
- Around line 1494-1497: Update _match_local_models to catch ResponseTooLarge
separately and raise TemplateCheckError with the new model_listing_too_large
code, while preserving server_not_running for connection and other existing
errors. Register model_listing_too_large in the error-code registry and
knowledge.json, then update affected tests to assert the distinct error.
In `@comfy_cli/skills/comfy/SKILL.md`:
- Around line 91-92: Update the documentation around _check_picks_locally to
avoid claiming that failed checks perform no file queries; state that non-ok
results, including failures after partial folder checks, must not be used while
acknowledging that some files may already have been checked.

…E-8974) An over-cap local model folder listing now raises `model_listing_too_large` instead of `server_not_running`, since the server did answer. Both `templates check` and `knowledge pick --check-local` report it. The skill, schema, CHANGELOG and pretty-mode footer say a non-`ok` check did not finish rather than that nothing was checked, and the CHANGELOG says a template is flagged as missing only when the gallery index is fresh.

🟡 Minor · Validate local model listings before matching.
comfy_cli/command/templates.py:1477-1517
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winValidate local model listings before matching.
The local
/models/<folder>contract returns a list of entries with string names. A non-list response becomes[], so_match_local_modelsreports installed models as missing. A non-string name can reach_basenameand raise an uncaught exception. Validate the listing shape and convert malformed responses to the existing structured local-check error.🤖 Prompt for AI Agents

Summary
available_locallyon a knowledge pick never looked at model files. The bestosspick for a capability could be one whose weights are not on this machine, and nothing said so.comfy knowledge pick <capability> --check-localruns thetemplates checkmodel check on eachosspick'stemplate. Partner picks and picks with no template are skipped.available_locally: false,unavailable_reasonandmissing_models, a count.available_locally: falsewith its own reason, when the gallery index is fresh.local_checkand no flag, and the rest are still checked. That is a workflow that cannot be fetched or parsed (template_fetch_failed,template_workflow_invalid_json), a template that loads models but declares none (unknown), or a template missing from a gallery index that could not be confirmed fresh (template_not_found).local_checkisokwhen the check ran. When the server is down, the gallery cannot load, or a folder listing is over the size cap, it carriesserver_not_running,gallery_load_failedormodel_listing_too_large, and no pick is marked. Some folders may already have been listed by then, so the check did not finish.Other changes:
check_cmdinto_gallery_rows,_template_workflowand_match_local_models, raisingTemplateCheckError.check_cmdrenders the same errors from it.comfy templates checktraceback onmain. An over-cap folder listing raises the newmodel_listing_too_largecode, registered inerror_codes.py, since the server did answer._is_walkable_folder_nameand percent-encoded before it reaches the local server URL._gallery_rowsloads withbackground_ok=False, likeshowandfetch, fortemplates checktoo.comfyskill, and CHANGELOG updated.Linear: BE-8974. This replaces the skill-only approach in #874, which closes when this lands. The cloud agent passes the flag on local after a release with it is pinned.
Envelope size
missing_modelsis a count becauseknowledge.pykeeps pick envelopes under the 4096 bytes the cloud agent passes through unchanged. I measured every capability in the bundle the cloud agent vendors, with everyosspick flagged.lipsyncgrows from 3650 to 4095 bytes.image-editis the only one over 4096, and it was already 4272 before this change. That measurement was not rerun after the unchecked-pick mark was added. The mark,"local_check":"template_workflow_invalid_json"at its longest, is about half the bytes of a flag, and the folder reason is one character shorter than the files reason.Testing
pytest .gave 7539 passed, 38 failed, 39 skipped, with one test deselected, before the last review fixes (a pretty-mode column and schema wording). The 38 failures are in build, deploy, host/port, secret redaction and similar tests. The same 38 fail on a cleanorigin/maincheckout with the same virtualenv. After those fixes,test_templates.py,test_knowledge.py, the error-code registry and discovery tests give 223 passed. The deselected test istests/comfy_cli/test_http.py::test_an_unloadable_supplement_falls_through_to_the_platform_roots. It fails onmainon my machine too, because its expected CA certificate count differs from this machine's store.test_templates.py,test_knowledge.pyand the error-code registry tests give 209 passed.ruff check .andruff format --check .pass with the pinned ruff 0.15.15.TestPickCheckLocalcovers missing files including a count of 2, all present, template not in the gallery, partner and template-less picks left unchecked, folder listing reuse, workflow fetch failures marking only that pick, a stale gallery index, a folder the server does not have, a loader with no declared models, server down and oversized listing dropping flags already made, gallery load failures, no checks without the flag, and pretty mode.templatestests pass. New ones cover a non-200 or over-cap workflow fetch, a wrong-shape gallery, deep JSON nesting, an over-cap folder listing, folder name encoding and a folder name with..inside it. Each new test fails on the previous commit.🤖 Generated with Claude Code
