…y surfaces
A caller that knows ComfyUI from the canvas can ask `workflow add-node` for
`Reroute`, or pass a subgraph instance uuid as a class. add-node already
refuses both with node_not_found.
The catalog surfaces (`nodes search` / `nodes ls`) never listed Reroute:
object_info carries no frontend-only node, so the name comes from prior
knowledge of the canvas. Two surfaces still let a caller walk into that wall:
- `nodes show Reroute` answered the generic "not found in the loaded
environment", so checking before adding taught nothing. It now gives the
same UI-only explanation `add-node` gives, with details.ui_only and no
difflib noise.
- `workflow ls-nodes` printed a canvas Reroute or a subgraph instance as a
plain {id, type} row. Rows now carry `ui_only: true` / `subgraph: true`
(only when set), so a raw CLI consumer can tell that type is not addable.
The rows stay listed because the graph must still be readable.

`workflow set-widget <id>.model.prompt_expansion_mode` on a
MinimaxHailuo03TextToVideoNode or MinimaxHailuo03FirstLastFrameNode still on
its default option was refused with "not found; available: <current option's
widgets>". That message never named the option to switch to.
The name is real. object_info gives `model` three options ("MiniMax H3",
"MiniMax H3 Max", "MiniMax H3 Max Turbo"), and only the two Max options
reveal prompt_expansion_mode. `nodes show` lists it under dynamic_options with
those keys. So the CLI did not misreport the node's widgets; it just did not
say which option to select. Both write paths now do:
- set-widget raises "exists only when model is 'MiniMax H3 Max' or 'MiniMax
H3 Max Turbo'; this node has model='MiniMax H3'. Set `<id>.model` ...
first". The wording has no "not found", so the sibling-address enrichment
does not add noise.
- set-slot's unknown_dynamic_sub_input warning carries `revealed_by` and
names those options in its hint instead of `<option>`.
Graph.dynamic_sub_widget_options() derives the options from
dynamic_combo_options(), the same data the widget catalog publishes.

…learly meant
`workflow set-widget <id>.aspect_ratio '16:9 (Landscape)'` on a
ResolutionSelector, whose options include '16:9 (Widescreen)', '9:16
(Portrait Widescreen)', '21:9 (Ultrawide)': difflib ranked the right option
first, but the refusal read as four equal guesses ("did you mean: a, b, c,
d?").
When exactly one option shares the rejected value's leading token (the
ratio), Port.best_combo_match() names it:
- the finding carries `best_match`, puts it first in `did_you_mean`, and the
message adds "('16:9 (Widescreen)' is the only option starting '16:9')".
- set-widget's hint becomes "use '16:9 (Widescreen)' — ...".
Nothing is auto-applied. The edit is still refused and the file is
unchanged. A single-token value (a filename) and a leading token shared by
two options get no best_match, so the model-file path keeps its current
behaviour.

…uessing aliases
`comfy generate gpt-image-1` failed with `Unknown model: 'gpt-image-1'`, and
`comfy generate seedream` with `Unknown model: 'seedream'. Did you mean:
seedance, ideogram?`. Neither is a typo of an alias:
- gpt-image-1 is an OpenAI image model. The `dalle` alias
(openai/images/generations) takes it as `--model`, but that schema types
`model` as a free string, so nothing linked the two. The error now says
`comfy generate dalle --model gpt-image-1 ...` (and dalle-edit for edits)
for gpt-image-1/1.5/2 and dall-e-2/3, the ids ComfyUI's OpenAI image nodes
send.
- seedream is ByteDance's image family. It is served at
byteplus/api/v3/images/generations, whose `model` enum lists seedream-*
ids, and `comfy generate` has no alias for that route. The error now names
the route and its model ids and points at the partner node. It no longer
suggests seedance, the video model.
The seedream case comes from the spec: any request body whose `model` enum
has a value starting with the name is reported, with the alias when the
route has one. A real typo ("flux-pr", "seedance-x") keeps the old difflib
"Did you mean".
Not done: adding a seedream alias. The images/generations route has no
adapter/poller/output wiring in `comfy generate`, so that is new feature
work, not a cheap fix.

…a command crashes `comfy --json workflow set-widget ...` could escape with a Python traceback instead of an envelope. Edit commands catch only ValueError, and nothing above them turned any other exception into ok:false. So a --json caller got an empty stdout plus a stack dump, which it cannot tell from a transport failure. _RootGroup.invoke already turns click usage errors into envelopes. It now does the same for any exception a command did not handle. It emits `internal_error` (details.exception = the type, message = "Type: text", command = the running command) and re-raises, so the traceback still reaches stderr and the exit code stays 1. Click's own control flow (typer.Exit after a handled refusal, Abort, usage errors) and pretty mode are unchanged. An envelope already emitted is never doubled. This does not fix any one crash; it makes every such crash a structured envelope, and the traceback kept on stderr locates the root cause. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…e partner node Review follow-up to bc3f23a. 1. The model-name hint returned early for any 4+ char name that prefixes a partner model enum. That hid difflib's "Did you mean" for plain alias typos: `flux` lost flux-2/flux-pro/... (recraft's flux1dev enum matched), and `stable`, `minimax` and `seed` regressed the same way. The hint is now appended after the alias suggestions and never replaces them. 2. A caller building a workflow runs `generate` with --emit-workflow. Only flux-2, flux-ultra, kling-i2v, nano-banana and seedance can emit, so a bare `comfy generate dalle --model gpt-image-1` hint was a dead end there. The hints now lead with the workflow route: - gpt-image-* names the Cloud partner node, OpenAIGPTImageNodeV2 (OpenAIGPTImage1 is deprecated), and says to set its model to the id. - Enum matches point at `comfy nodes search <id>`. - Each `comfy generate <alias> --model` line says whether that alias can also --emit-workflow. - The id is echoed lowercased. Tests: flux/stable/minimax/seed keep their alias in "Did you mean"; gpt-image-* names the node before the dalle route and mentions --emit-workflow; seedream still names its byteplus images route; flux-pr keeps its typo suggestion.

…rnal_error Review follow-up to 7ac54e7. The internal_error envelope goes to stdout, so it ends up in the model's context. The raw traceback on stderr never did. - details.traceback: the innermost 1-3 frames as `file:line:func`, enough to locate the crash from the envelope alone. No source text. - The message is capped at 500 characters. - The message is scrubbed of URL query strings (`?api_key=...`), bearer tokens, `token=`/`api_key:`/`password=`-style pairs and `user:pass@` userinfo. The URL path survives. It also pins the control-flow guard. typer.Exit(0) and click.Abort raised with no prior envelope must not become internal_error. Both new cases fail if `not _is_click_control_flow(error)` is removed (checked). Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Review nit on 712e367. `'flux dev.safetensors'` shares its leading word with `'flux schnell.safetensors'`, but that is a different model, not a relabelled option like '16:9 (Landscape)' -> '16:9 (Widescreen)'. A value ending in a file extension no longer gets best_match. difflib's did_you_mean is unchanged. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Review follow-up. - docs/json-output.md: a "CLI-wide codes" table (usage_error, internal_error with details.exception/command/traceback, the 500-char cap and the redaction rules) and a "Workflow-edit refusal fields" table (`best_match` on unknown_enum_value, `revealed_by` on unknown_dynamic_sub_input, ls-nodes `ui_only`/`subgraph`). "Process-level termination" now points at internal_error for crashes inside the CLI. - comfy-debug skill: what internal_error means and what to do. Re-read state before retrying, take another route on a repeat, and do not retry-loop. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

This PR improves agent-facing diagnostics across workflow editing and generation: it identifies UI-only/subgraph nodes, names dynamic-combo options that reveal requested widgets, promotes unambiguous enum matches, adds partner-model routing hints, and emits structured internal_error envelopes for uncaught exceptions in JSON mode. The focused coverage is strong, and the branch merges cleanly with current main.
One security issue should be addressed before merge: Basic-auth credentials are only partially redacted from the new stdout error envelope. Authorization: Basic <credential> retains <credential>, potentially exposing it to logs or agent context. I left a line comment with a reproducer and suggested regression test.
I ran the 39 focused tests added/affected by this PR plus Ruff lint and formatting checks; all passed.

The redaction leaves HTTP Basic credentials exposed. For example, Authorization: Basic dXNlcjpwYXNzd29yZA== becomes Authorization: *** dXNlcjpwYXNzd29yZA==: this pattern consumes only Basic, while the base64 credential remains in the new stdout envelope. Please redact the complete Basic-auth value and add a regression case alongside test_the_message_is_capped_and_secrets_are_redacted.

Good catch, thanks. Fixed in 2cbe585. The whole Authorization value is masked now (scheme plus credential, any scheme), with regression cases for Basic and Bearer next to the existing redaction test.
…l Authorization values A crash in the root callback happens before the --json renderer is installed, so the envelope path saw the pretty default and wrote nothing. Resolve the mode from the parsed root flags instead, without the version lookup that may be what failed. Redaction now treats an Authorization value as scheme plus credential for any scheme (Basic, Bearer, Token, Digest) instead of masking only the scheme word. The control-flow test now asserts exact exit codes. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…onest nested hints An interior write (`<instance>/<inner>.<widget>`) skipped the widget lookup, so a sub-widget the current dynamic-combo option hides recorded an op and wrote nothing. It now goes through the same resolution as a top-level node and gets the same refusal. For a nested dynamic combo, the set-slot warning named the outer selector (`model`) instead of the nested one (`model.mode`) and dropped the option list. It now names the nested selector when the node has it. When the node's outer option hides the nested selector, neither path suggests setting it any more: set-widget keeps the plain refusal and the warning falls back to the outer selector with no option hint.

The masking fix works. I ran the _SECRET_PATTERNS tuple from this head against fifteen inputs rather than reading it, including the exact case from the earlier thread, and Authorization: Basic dXNlcjpwYXNzd29yZA== comes out as Authorization: ***. Nothing leaked on any of them: Basic, Bearer, Digest with quoted comma separated params, Proxy-Authorization, an all lowercase header, no space after the colon, a tab separator, a dict repr in either quote style, user:pass@ userinfo, ?api_key=, and a bare token= pair. WWW-Authenticate: Basic realm="x" is correctly left alone, which is easy to get wrong with a pattern this shape.
One real problem with how the two authorization patterns interact, inline below. The envelope itself is a good idea and _traceback_tail deliberately carrying no source text is the right instinct for something that lands in a model's context.

issue: (non-blocking, but it defeats part of what this envelope is for) this pattern and the quoted one above it are not mutually exclusive, and because both run as independent sub passes the second one eats the rest of the line. For the shape most likely to appear in an exception message, a headers dict:
in : {'Authorization': 'Bearer tok123', 'X-Request-Id': 'req-abc-789', 'Content-Type': 'application/json'}
out: {'Authorization':***
Tracing it pass by pass: the Bearer pattern masks the credential, then the quoted pattern at line 190 does its job correctly and leaves {'Authorization': '***', 'X-Request-Id': 'req-abc-789'}. Then this pattern runs on that output and matches Authorization': '***', 'X-Request-Id': 'req-abc-789'}. The (?!["']) guard is meant to stop exactly that, but ["']? is optional and \s* can match empty, so the engine backtracks until group 1 ends at Authorization': and the lookahead is tested against a space instead of the quote. [^\r\n]+ then takes everything to end of line.
The secret is still masked so this is not a leak, but the request id, the content type and any trailing text go with it, and those are the parts a --json caller needs to act on the crash. Would folding the two into one alternation with the quoted branch first, applied once, be cleaner than two passes that can see each other's output? A regression case with a header after Authorization would pin it, since every existing case puts the header last, which is why this survived.
There was a problem hiding this comment.
good catch, fixed in 5b72abd. the two authorization patterns are now one alternation, quoted branch first, applied in a single pass. so each value gets masked once and nothing re-reads the '***' output. added regression cases with a header after Authorization, including your exact dict, a double quoted one, a Digest value with trailing text, and a header line followed by another line. X-Request-Id and Content-Type survive now. the older Basic, Bearer, Token, Digest and dict cases still pass.
The quoted and unquoted Authorization patterns ran as two separate re.sub passes. The unquoted one could backtrack its optional quote and whitespace, re-match the quoted pass's output, and mask everything to the end of the line. A headers dict lost every header after Authorization, plus any trailing text. Fold both into one alternation (quoted value first, then unquoted to end of line) applied in a single pass. Add regression cases with headers and text after the Authorization value. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
