Summary

Adds apps +features and apps +feature-enable so an app can turn on a server-side business feature from the CLI. The first feature is database (the app's PostgreSQL database): a full_stack app no longer needs to be created with a database, or upgraded through a cloud session, to get one. Server rejections are explained with a specific subtype and an actionable hint, and the follow-up steps after a successful enable differ between a Miaoda sandbox and local development.

Changes

  • apps +features — GET /open-apis/spark/v1/apps/:app_id/features; prints each feature's name and enabled only. --operation-ref <idempotent_key> also reports the enable operation the server keeps for that key.
  • apps +feature-enable --feature database — POST /open-apis/spark/v1/apps/:app_id/features/database/enable with only an idempotent_key in the body.
    • Network failures are replayed with the same key; server answers are never re-sent with a new key.
    • --idempotent-key resumes an earlier attempt: the kept operation is read first and reported, waited on, or (for a retryable failure) re-sent under the same key.
    • A running operation is polled through the read-only endpoint for at most 60s; stopping never cancels or rolls back the server-side operation.
    • A 40913 answer first looks up the operation kept for this key, so a network replay that races its own first attempt is followed instead of being reported as a conflict.
    • Keys are sent in the lower-case form the server stores.
  • Error mapping (Studio codes, also in the gateway's 33xxxxx form, e.g. 3340914):
    • 40914 → failed_precondition: the app is not a new-contract app; enable the database in Miaoda cloud development instead (app_identity_missing asks for a platform-side repair).
    • 40915 → failed_precondition, not retryable: the key can no longer be used (superseded, another caller's, or never created); check +features, and if still needed run +feature-enable again without --idempotent-key; never retry the same key. Applies to +feature-enable (including the lookup before a resume) and +features --operation-ref.
    • 40001 → invalid_parameters, 40009 → feature_not_available, 40912 / 40913 → conflict (per-reason hints when the reason is present), 42900 → rate_limit, retryable with the same key.
    • Only outcomes that may still change (network failures, server errors, 50008 result unknown, failed reads while polling) point at the --operation-ref query and the same-key resume.
  • next_steps after a successful enable — inside a Miaoda sandbox (MIAODA_AUTHN_CODE is set) the platform applies the new database, so the steps say to wait and verify one real read/write; locally they keep +env-pull, restarting the dev process, and the dev-environment guard. The help tips and the "app has no database" hint follow the same split.
  • apps +env-pull — applies the database keys explicitly: an explicit disable (FORCE_FRAMEWORK_DISABLE_DATAPASS="true" with both connection keys present and empty) clears SUDA_DATABASE_URL, FORCE_DB_CONNECT_URL and FORCE_DB_BRANCH; an exported connection pins FORCE_DB_BRANCH=dev. Both report restart_required and list shell variables that would shadow .env.local (names only, never values). An empty SUDA_DATABASE_URL is no longer reported as a database.
  • Docs — lark-apps skill routing rows, a new lark-apps-features.md reference, updates to the env-pull and local-dev references, README feature rows, and the apps E2E coverage table.

Test Plan

  • Unit tests pass (shortcuts/apps: feature read/enable, resume, polling, replay races, error mapping for both code forms, sandbox vs local next_steps, env-pull database keys; tests/cli_e2e/apps dry-run cases) — run by CI
  • gofmt and node scripts/skill-format-check/index.js pass locally
  • Manual local verification confirms the lark-cli apps +features / lark-cli apps +feature-enable flow works as expected — to be done with this PR's preview package

Update the stale denominator in the apps +export row.

This change raises the selected-set denominator to 28 on Line 4. The apps +export row on Line 73 still says "added outside the 26-command denominator above". That number now contradicts the Metrics section.

Apps can now turn on server-side business features from the CLI. The
first one is pg (the app database), so a full_stack app no longer has to
be created with a database or upgraded through a cloud session to get
one.

- +features lists each feature's name and enabled flag
  (GET /open-apis/spark/v1/apps/:app_id/features). With --operation-ref it
  also reports the enable operation kept for that key.
- +feature-enable --feature pg posts only an idempotent_key. Network
  failures are replayed with the same key; --idempotent-key resumes an
  earlier attempt from the operation the server keeps for it; a running
  operation is polled for at most 60s without re-sending the write. A
  40913 answer looks up the operation kept for this key first, so a
  replay that races its own first attempt is followed instead of being
  reported as a conflict.
- Studio error codes (also behind the gateway's 33xxxxx form) are
  explained: 40914 not a new-contract app (enable the database in Miaoda
  cloud development), 40915 the key can no longer be used (check
  +features, then start over without --idempotent-key), 40001, 40009,
  40912, 40913 and 42900 get their own subtype and hint. Only outcomes
  that may still change point at the --operation-ref query.
- next_steps after a successful enable depend on where the command runs:
  inside a Miaoda sandbox (MIAODA_AUTHN_CODE is set) the platform applies
  the database; locally it is +env-pull and a restart of the dev process.
- +env-pull applies the pg keys explicitly: an explicit disable clears
  the connection keys and FORCE_DB_BRANCH, an exported connection pins
  FORCE_DB_BRANCH=dev, and it reports restart_required and shell
  variables that would shadow .env.local (names only).
- Keys are sent in the lower-case form the server stores.
- lark-apps skill, references and the apps E2E coverage table cover the
  new commands.

yxy-bd force-pushed the feat/202610-jspage-new-contract-integration branch from f258dcb to e4e0d8d Compare October 14, 2026 15:43
A server that does not implement the app features API answers every call
through the OpenAPI gateway with HTTP 500 and code 2200 "Internal
Error". The CLI classified that as a retryable server error, and
+feature-enable told the caller to resume the same key, so an agent
pointed at such a server kept retrying a call that cannot succeed.

The gateway gives the same answer for a passing upstream failure and the
response carries nothing that tells the two apart, so a 2200 from the
feature endpoints is now re-checked with one plain read of the features
endpoint. Only when that read fails the same way is the error reported
as feature_not_available, not retryable, with a hint to upgrade the
server or enable the database in Miaoda cloud development. A re-check
that succeeds keeps the original error and its same-key resume guidance;
for +features the successful second read is simply returned.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Do not treat two 2200 responses as proof that the feature API is absent.

An upstream outage can return 2200 for both the original request and this immediate GET. explainFeatureAPIMissing then marks an enable POST as non-retryable and removes same-key recovery guidance, although the POST outcome is unknown. Preserve the original error and recovery guidance unless the server provides a definitive capability signal. The double-GET path in shortcuts/apps/apps_features.go and the tests that expect a final error after two 2200 responses need the same correction.

…redential failures

An authentication failure on +feature-enable, on the key lookup before a
resume, or on +features --operation-ref used to fall through to the
recovery for outcomes that may still change, so the caller was told to
resume the same idempotent_key. No key can succeed until the user
authorizes again, and an agent following that hint kept retrying.

- Code 221801 ("miaoda UAT expired and cannot refresh, need
  reactivate"), which the Miaoda sandbox proxy returns once the user
  credential can no longer be refreshed, is classified as
  authentication / token_expired next to 221800, so it exits as an
  authentication error and is not retryable.
- The feature commands now handle any authentication failure the same
  way the CLI's missing-login error does: not retryable, and with the
  standard user-authorization recovery when the producer left no hint.
  That recovery is projected per distribution, so builds without
  `auth login` keep the generic re-authorization wording.
@yxy-bd
yxy-bd requested a review from liangshuo-1 as a code owner October 14, 2026 19:54
The Miaoda sandbox proxy answers a credential it cannot accept with HTTP
401 and its own JSON body ({"status_code":"k_gw_ec_000032",...}), not a
Spark envelope. The shared classifier turns such a status into an api
error with code 401, so +feature-enable still told the caller to resume
the same idempotent_key and +features pointed at the app id.

Spark answers its own failures inside an envelope and neither the
features service nor the OpenAPI plugin answers with HTTP 401, so a bare
401 reaching these commands is a credential rejected in front of Spark.
On the enable, the key lookup before a resume and +features it is now
re-typed as an authentication error (token_invalid, code 401) and gets
the same handling as code 221801: not retryable, with the standard
user-authorization recovery. +export already maps its 401 the same way.
The feature name says what the app gets rather than which engine backs it,
matching how the db-* commands refer to the app's database. The CLI accepts
only `--feature database`; `pg` is rejected during validation.
