Nothing blocking. Two findings, both fixed in c70db03; one left, with the reason.
Must
- Resilience: a dropped connection to the estimate stopped the create
comfy_cli/command/deploy_up.py:102. The guard caught onlyDeployAPIError, and the client maps timeouts and URL errors but not a reset connection (ConnectionResetError) or an oversized answer (ResponseTooLarge), so either one endedupbefore it created anything, for a number that is only advice. Fixed: both are caught; theconnection_resetandtoo_largecases fail without it.
Optional
- Contract: the skill told an agent to relay the estimate before watching, which
--json --watchcannot docomfy_cli/skills/comfy-deploy/SKILL.md:157. Under--jsonthe estimate arrives in the one envelope when the watch ends. Fixed: the skill says to runupwithout--watch, relay it, thencomfy deploy status --watch.
Left, with the reason
- This touches
up_cmdincomfy_cli/command/deploy.py, which #913 also rewrites. Whichever merges second rebases; the change here is two lines before the watch.
Clean: a restart or an edit asks for nothing, malformed numbers give no estimate rather than a wrong line, the schema accepts the new field and nothing else changed shape.
Checked: pytest 7883 passed, 2 failed, both failing on main too; ruff check and ruff format --check clean; each new test run once with its behaviour removed and failed.

Nothing blocking. Self-review of the switched-off push, head c4f6019. No findings.
Clean: {"enabled": false} leaves the create as it was. up prints no line and writes nothing to stderr, and --json carries no estimate. That holds even when the answer also carries numbers. The schema pins estimate.enabled to true when present. The skill tells an agent the absence is not an error and not to retry.
Checked: pytest 7885 passed, 2 failed, the same two that fail on main; ruff check and ruff format --check clean. test_a_switched_off_estimate_prints_nothing_and_adds_nothing[with_numbers] fails with the enabled check removed.

One blocking correctness issue: a transport failure in the optional estimate can prevent deployment. Also noted a nonblocking duration-rounding issue. Validation: 189 targeted tests passed with locked dependencies under Python 3.10 and coverage; changed-file lint/format passed. The truncated-response failure was reproduced separately with a local HTTP server.

[P2] Ignore truncated HTTP responses from the optional estimate
A server/proxy closing a chunked estimate response early raises http.client.IncompleteRead from read_capped. That exception inherits HTTPException, not OSError, so it escapes this guard and aborts up before create_deployment is called. Reproduced with a local HTTP server returning a truncated chunked 200 response: reconcile_up raised IncompleteRead with zero create calls. Please also handle HTTP protocol/read failures as unavailable estimates and add a regression test, so this advisory request cannot prevent deployment.

Both fixed in 6f3d18e.
- Truncated estimate response (
deploy_up.py:104):http.client.HTTPExceptionnow joins the estimate's guard, soIncompleteRead(andBadStatusLine) count as no estimate and the create goes ahead. Regression test serves a truncated chunked 200 on loopback and checks the deployment is created; it fails without the fix withIncompleteRead. - Hour range lower bound (
deploy_up.py:122): same rule as the site, a short end under half an hour keeps the range in minutes (840-7800 s -> "14-130 min"). Boundary case added.

| low_hours = max(0.5, (low // 30) / 2) |

[P3] Keep the lower duration bound when switching to hours
For an estimate of 840–7800 seconds (14–130 minutes), this renders 0.5-2.5 h: the 30-minute minimum excludes the service’s 14–30 minute interval, contrary to the outward-rounding rule above. Keeping minutes when the lower bound is under half an hour, or allowing a smaller lower hour bound, would preserve the quoted range. Nonblocking, but worth covering with a boundary test.

Nothing blocking.
Second self-review, of the push answering the review, head b87e54b.
Optional
- Readability: a range can now read as long minutes
comfy_cli/command/deploy_up.py:122. With the short end under half an hour the whole range stays in minutes, so a wide estimate can print as something like "18-181 min". Left on purpose: it is the service's own range, unrounded, and it matches what the site prints for the same answer.
Clean: http.client.HTTPException joins the guard (deploy_up.py:105), which covers IncompleteRead and BadStatusLine; RemoteDisconnected was already an OSError. A malformed body still reaches the guard as an answer missing its numbers, since request_json returns no JSON for it. Only the advisory estimate read changes; the create and the watch keep their own error handling.
Checked: ruff check and format clean; full suite 7888 passed, 2 failed, the two that fail on main too (test_non_pep440_installed_version_is_unknown_not_a_crash, test_an_unloadable_supplement_falls_through_to_the_platform_roots). The three new tests fail on c4f6019 and pass here; the loopback one (test_deploy_up.py:715, a truncated chunked 200) fails there with IncompleteRead(19 bytes read, 45 more expected) and no create.

…ore it waits (BE-16057)
Just before a create, `comfy deploy up` asks the deploy service for its
estimate of the new deployment (GET /v1/deploy-estimate with the release, GPU
class and region it is about to send) and prints one line before any watch
starts: a range until ready, rounded outward, and how many GB of models have to
download ("at least" when some models have no recorded size). Under --json it
is `estimate` in the output, added to the published schema.
The estimate is advice. A service that has no route for it, refuses it, or
answers without the numbers leaves the create exactly as before, and a restart
or an edit asks for none.
…ate; the skill says how an agent relays it before a watch (BE-16057) A reset connection or an oversized answer escaped the estimate's guard, which caught only the deploy client's own errors, and stopped up before it created anything. Both now leave the create as it was. Under --json the estimate arrives with the one envelope, so the skill no longer tells an agent to relay it before watching when it cannot see it until the watch ends: run up without --watch, relay it, then follow with status --watch.
… (BE-16057)
The deploy service answers {"enabled": false} when the estimate is switched
off. up now treats that as no estimate, whatever else the answer carries: no
line for a person, no estimate under --json, no warning. The schema pins
estimate.enabled to true when present, and the skill tells an agent the
absence is not an error.
…nd a short end under half an hour stays in minutes (BE-16057) A server or proxy that closes a chunked estimate response early raises http.client.IncompleteRead, an HTTPException rather than an OSError, so it escaped the guard and aborted `up` before the create. Any HTTP protocol failure now counts as no estimate, like every other failure of that advisory read. A test serves a truncated chunked 200 on loopback and checks the deployment is still created. A range whose long end passes two hours switched to half hours, and the smallest half hour raised a short end under thirty minutes: 14-130 min read as 0.5-2.5 h. Such a range now stays in minutes, matching the site.
…as one flow (BE-16057)

Head 3b8b951: rebased onto main after #913 merged, plus one docs commit.
What the rebase had to reconcile:
CHANGELOG.md: both entries kept, #913's first.comfy_cli/command/deploy_types.pyUpResult.payload: both fields kept;progresswhile the deployment is coming up, thenestimateon a create.tests/comfy_cli/command/test_deploy_up.py: kept #913's ending for the unhealthy test (the watch stops, exit 1) and dropped this branch's older ending that expectedunhealthy -> ready; the estimate tests follow it unchanged. The import line keepsDeployClientand dropsDEPLOY_POLL_SECONDS, which nothing uses any more.
Behaviour after the rebase: up prints the estimate line before it starts following the deployment, which is now the default (comfy_cli/command/deploy.py:285-287); under --json the estimate is in the one envelope, after the watch.
Optional
- Scope: the skill still told an agent to run
up"without--watch"comfy_cli/skills/comfy-deploy/SKILL.md:189. Since #913 that no longer returns before the wait. Fixed in 3b8b951: it saysup --no-watch, relay, thencomfy deploy status --watch, and that a person at a terminal sees the estimate before the watch.
Checked: ruff check and format clean; full suite 7976 passed, 2 failed, 38 skipped, the two failures being the ones main already has. One earlier full run stalled at 88% for over ten minutes and was stopped; the deploy-up file alone (57 tests) and the full rerun both completed, so the stalled test was not identified.

Blind pass (Codex on the pre-ask prompt) on 6fcd267. Two findings, both reproduced and fixed in 7a52f50.
- Contract:
--jsoncould pass on an estimate that breaksdeploy_up.jsoncomfy_cli/command/deploy_up.py:109. Only the three required numbers were checked, and the whole answer goes into the envelope, so"bytesTotal": -1produced output that fails the published schema. Each optional field the schema constrains (bytesTotal,bytesHeldas counts,atLeast,measuredas booleans) is now checked when present, and an answer that fails is treated as no estimate. Three new cases intest_a_create_the_service_cannot_estimate_still_deploysfail on 6fcd267. - Correctness: a backwards range printed as one confident number
comfy_cli/command/deploy_up.py:116.etaSecondsLow: 3600, etaSecondsHigh: 60printed "Expected ready in 60 min". It is now treated as no estimate;runs_backwardsfails on 6fcd267. The service cannot send one today (its rate parser refuses high-to-low ranges); this reverses the earlier answer on the CodeRabbit thread, since both passes flagged it and the check costs one line. The site does the same.
In 6fcd267, before this pass (CodeRabbit threads): only enabled: true shows an estimate, as the site reads it; a short end under a minute reads 0 instead of 1.
Left, with the reason: the schema's per-field constraints are now exercised through the cases above rather than by removing constraints one at a time.
Checked: ruff check and format clean; full suite 7984 passed, 2 failed, 38 skipped, the two failures being the ones main already has.

TL;DR:
comfy deploy upsays roughly how long a new deployment will take to come up, before it starts waiting:Expected ready in 8-81 min (42.0 GB of models to download).Under--jsonthe same numbers areestimatein the output. Today a create prints its id and status and nothing about the wait.Why: a deployment with large models can take far longer to come up than one without, and neither a person nor an agent driving the CLI can tell that from a status that just says it is coming up.
Before / After
upasks the deploy service for its estimate (GET /v1/deploy-estimatewith the release, GPU class and region it is about to send) and, for a person, prints one line before any--watchbegins. The range is rounded outward (short end down, long end up), in minutes below two hours and half hours above. The download says "at least" when some models have no recorded size, "nothing to download" when none are left to fetch. Today there is no such line (Before).--json:estimateis added to thedeploy uppayload and toschemas/deploy_up.json, present only when this run created the deployment and the service gave one.{"enabled": false}(its estimate switched off),upprints no line and no warning, and--jsoncarries noestimate, whatever else the answer holds. The schema pinsestimate.enabledtotruewhen present. No CLI release is needed to follow the switch.upwithout--watch, tell the user, thencomfy deploy status --watch, since under--jsonthe one envelope arrives when the watch ends.Part of BE-16057.

Each new test fails with its behaviour removed (no estimate asked, a refusal or a dropped connection stopping the create, unchecked numbers, the line printed after the watch, the short end rounding up, a switched-off answer printed).Not run: against a deploy service that serves the route; the client is covered by the wire table and the fake control plane.
