Thanks for this — the schema work, sequential/parallel orchestrator, and env-status path are nicely factored and the unit tests (real tempdir + SDK-boundary injection for StackInfoFetcher) are a good pattern. However I think there are three blocking issues that need fixes before this can merge; they match the Feature test: FAIL the autonomous tester reported:

1. --parallel / --continue-on-error are accepted by the CLI and validator but never reach the orchestrator, so they are silent no-ops.
2. As soon as a user writes an object-shape aws-targets.json ({ targets, environments }), every other command that goes through ConfigIO.readAWSDeploymentTargets() throws a schema validation error — including agentcore deploy --target …, agentcore status, the TUI, etc. The feature only "works" in the two helper functions that manually re-parse the file.
3. EnvironmentStep / AssignTargetsPanel and buildAwsTargetsConfig are implemented and unit-tested but never rendered from CreateScreen or useCreateFlow, so T13/T14 are effectively dead code — there is no UX path to produce the new config shape.

Details inline.

[agentcore-cli-automation]

EnvDeployOptions is missing parallel and continueOnError, and handleEnvDeploy below never forwards them to deployToTargets. Combined with command.tsx not passing them through either, agentcore deploy --env dev --parallel and --continue-on-error are accepted by the validator but have zero runtime effect — every env deploy is sequential fail-fast regardless of flags.

Please:

• Add parallel?: boolean and continueOnError?: boolean to EnvDeployOptions.
• Forward them into the deployToTargets(..., { environmentName, parallel, continueOnError, log }, ...) call (line ~799).
• Pass cliOptions.parallel / cliOptions.continueOnError from handleDeployCLI in command.tsx (line ~73).

A test that exercises handleEnvDeploy with parallel: true and asserts the orchestrator observes it (e.g. by spying on deployToTargets or by verifying concurrent execution) would prevent this from regressing.

[agentcore-cli-automation]

When the file is in the new object shape, this function correctly parses environments, but then calls configIO.resolveAWSDeploymentTargets() to get the targets list — and resolveAWSDeploymentTargets → readAWSDeploymentTargets validates the file against AwsDeploymentTargetsSchema (the array-only schema, see src/lib/schemas/io/config-io.ts:128). That will throw ConfigValidationError on object-shape files.

The same problem exists in every other code path that reads targets via ConfigIO, so as soon as a user has the new shape on disk:

• agentcore deploy --target … → configIO.resolveAWSDeploymentTargets() throws (actions.ts:132)
• agentcore status → loadStatusConfig throws (status/action.ts:78)
• useAwsTargetConfig → throws (hook line 118)
• Even handleEnvDeploy itself throws from this line

The object form is currently only readable via the three hand-rolled readFile + AwsTargetsSchema.parse sites (this function, readEnvironmentsFromAwsTargets in status, and the hook), and any CLI path that touches ConfigIO.readAWSDeploymentTargets() is broken end-to-end on object-shape configs.

Options to fix:

1. Teach ConfigIO about both shapes (recommended): change readAWSDeploymentTargets to accept a schema that unions array and object forms (or to try AwsTargetsSchema first and fall back to AwsDeploymentTargetsSchema), returning the array of targets. Add a sibling readAwsTargetsFull() that returns { targets, environments }. Then remove the ad-hoc readFile/JSON.parse/AwsTargetsSchema.parse duplication from actions.ts, status/action.ts, and useAwsTargetConfig.ts.
2. Keep the helper, but also have it replace the resolveAWSDeploymentTargets() call on line 771 with direct use of the targets already parsed out of AwsTargetsSchema.parse(parsed) plus the region fallback logic copied out of ConfigIO (less ideal — duplicates fallback logic and still leaves every other read path broken).

Either way, an integration test that writes an object-shape aws-targets.json to a temp dir and exercises handleDeploy --target <name> and loadStatusConfig() (not just the env-specific paths) would catch the regression.

[agentcore-cli-automation]

EnvironmentStep, AssignTargetsPanel, and buildAwsTargetsConfig are exported from this barrel and unit-tested, but grep shows they are not imported from CreateScreen.tsx or useCreateFlow.ts anywhere — only from tests and this barrel. So tasks T13 ("Add environment setup step to create TUI") and T14 ("Target-to-environment assignment + write environments on create") are effectively unimplemented: a user running agentcore create cannot reach this wizard step, and no code path ever writes the object-shape { targets, environments } to disk (the only writeAWSDeploymentTargets callers still pass AwsDeploymentTarget[]).

Please either:

1. Wire EnvironmentStep → AssignTargetsPanel → buildAwsTargetsConfig into useCreateFlow / CreateScreen and add a writeAwsTargetsFull({ targets, environments }) (or extend writeAWSDeploymentTargets) so the new shape is actually produced; or
2. Remove these components from this PR and land them in a follow-up when the create flow wiring is ready, so the surface this PR ships matches what it actually delivers.

Related: issue #2 above (ConfigIO only accepting the array shape) means even if a user hand-edits aws-targets.json into the object form, the rest of the CLI is broken. Wiring #1 without also fixing ConfigIO would ship a create flow whose output is immediately unusable.

[agentcore-cli-automation]

The three blockers from the prior review look fixed in d3becdc — nice work wiring parallel / continueOnError end-to-end, teaching ConfigIO about both shapes via readAwsTargetsFull + peekAwsTargetsShape, and hooking EnvironmentStep / AssignTargetsPanel into CreateScreen.

I found two new issues specific to the interactive TUI env-deploy path (DeployScreen.tsx:208-224) that I think should be addressed before merge. Both are in the same useEffect. Details inline.

[agentcore-cli-automation]

Hard-coded autoConfirm: true silently auto-approves teardown deploys in the interactive TUI.

When the user picks an environment from the TUI picker, handleEnvDeploy is invoked with autoConfirm: true regardless of user intent. Inside handleDeploy (actions.ts:168-177), autoConfirm: true is what bypasses the teardown confirmation guard:

if (context.isTeardownDeploy && !options.autoConfirm) {
  // returns an error asking the user to pass --yes
}

So if any target in the selected environment would be a teardown (e.g. the user removed resources from their project spec), this TUI path will delete the stack with no prompt. On the CLI --env path the user at least had to type --yes; here there's no equivalent signal.

Options to fix:

1. Pass autoConfirm: autoConfirm (the prop) instead of hard-coding true, and add a confirmation prompt in the TUI before transitioning envChoice to 'running' when any target would be a teardown. Matches the per-target TUI behavior (phase === 'teardown-confirm').
2. Pass autoConfirm: false and add a generic "Deploy N targets to env X?" confirmation in the picker that the user has to confirm before running. Simpler, but still exposes teardown to the user via the per-target preflight inside each handleDeploy.
3. Leave it as is, but gate the env-deploy TUI path behind the autoConfirm prop (i.e. only auto-confirm when the outer DeployScreen already has autoConfirm set).

Option 1 is closest to the single-target TUI behavior.

[agentcore-cli-automation]

The interactive TUI env-deploy shows no per-target progress.

onLog: () => undefined discards every progress + summary line the orchestrator emits, and onProgress / onResourceEvent aren't wired in either. The UI goes straight from "Deploying targets…" to the final aggregate result — for an env with e.g. 3+ targets, the user has no indication of which target is running, no step progress (Bootstrap / Synth / Deploy), and no way to tell that a long deploy is still making progress vs. hung.

The CLI --env path logs these lines to stdout via onLog: line => console.log(line) (command.tsx:83), so the information is already produced — it just isn't surfaced in the TUI.

Options to fix:

1. Plumb onLog into a piece of state (e.g. const [envDeployLog, setEnvDeployLog] = useState<string[]>([])) and render the last N lines under "Environment: {name}". Cheapest option, reuses the orchestrator's formatted progress lines.
2. Plumb onProgress (per-step) and/or render a per-target StepProgress list driven by the existing targetStatuses pattern. More work but matches the rest of the deploy TUI.
3. If a richer per-target TUI is out of scope for this PR, at minimum render a "[i/N] Deploying to {target}…" line by hooking onLog and filtering for the orchestrator's bracketed progress header.

[agentcore-cli-automation]

The two prior rounds of findings look addressed in d3becdc / eb71658 — --parallel / --continue-on-error are now plumbed through, ConfigIO accepts both on-disk shapes via readAwsTargetsFull + peekAwsTargetsShape, and EnvironmentStep / AssignTargetsPanel are wired into CreateScreen with a writeAwsTargetsFull that actually persists the new shape. Schema + orchestrator unit tests are good (real temp dirs, injected deploy fn, no mocking of the unit under test).

One new blocker on the --parallel path that I don't see covered elsewhere: handleDeploy has per-invocation process-global and on-disk side effects that race when invoked concurrently, so agentcore deploy --env <multi-region-env> --parallel will silently produce wrong results across regions. Details inline.

[agentcore-cli-automation]

--parallel has real concurrency bugs inside handleDeploy — running targets concurrently across different regions will produce incorrect / corrupt results.

The orchestrator in multi-target.ts is correct, but each concurrent handleDeploy call it fans out does three things that are not safe to run in parallel within the same process / project:

1. Global process.env mutation. handleDeploy calls applyTargetRegionToEnv(target.region) (actions.ts:144), which sets process.env.AWS_REGION and AWS_DEFAULT_REGION globally and returns a restoreEnv called in finally. Two targets in different regions will race on these env vars — the later writer wins, so the SDK / CDK toolkit clients constructed afterwards (inside synthesizeCdk, checkBootstrapNeeded, the post-deploy CFN / identity calls, etc.) can pick up the other target's region. The interleaved restoreEnvs can also leave AWS_REGION pointing at a region that isn't the user's original.

2. Shared cdk.out directory and CDK toolkit lock files (synthesizeCdk → path.join(cdkProject.projectDir, 'cdk.out'), plus cleanupStaleLockFiles). cleanupStaleLockFiles is designed to clean up after dead processes; for two live parallel synth / deploy calls on the same project, they will contend for the same directory and lock files — producing confusing ENOENT/EEXIST failures at best, and at worst one synth's assembly becoming visible to the other's deploy.

3. Read-modify-write race on deployed-state.json. handleDeploy does readDeployedState() → mutate → writeDeployedState() in several places (actions.ts:283, 498, 574, 599, 630, 661). Two parallel targets both read the same pre-state, each writes back only their own slice, and whichever writes last overwrites the other target's updates. Subsequent agentcore status then shows stale or missing resources for the clobbered target.

Options to fix:

1. Scope region per-deploy without mutating process.env. Thread target.region through handleDeploy so every SDK / CDK client that defaults from env vars receives an explicit region instead. Remove (or gate to sequential-only) applyTargetRegionToEnv. Combine with per-target cdk.out directories (e.g. cdk.out/<targetName>) and a ConfigIO.updateDeployedState(fn) that does atomic read-modify-write under a mutex keyed on the state file. This makes --parallel correct for any combination of regions.

2. Serialize the unsafe sections inside handleDeploy with a process-scoped mutex around applyTargetRegionToEnv → synth → CFN calls → writeDeployedState. Simplest change, but only the CFN CREATE_IN_PROGRESS wait actually overlaps — so most of the point of --parallel is lost.

3. Disable --parallel for now and land it as a follow-up once build(deps): bump diff and @aws-cdk/cloudformation-diff #1 is in place. validateDeployOptions can reject --parallel with an explanatory error. This avoids shipping a flag that silently corrupts state when used across regions.

Any of these is fine — option 1 is the long-term correct answer, option 3 is the lowest-risk for this PR. Whatever is chosen, please also add a test that fans out handleEnvDeploy with parallel: true across two distinct-region targets and asserts (a) each deploy's SDK calls use its own region and (b) the final deployed-state.json contains both targets' resources — the current multi-target.test.ts parallel test only exercises the orchestrator, not the full handleEnvDeploy → handleDeploy stack.
