Adds repeatable list flag handling across the mail send, draft, reply, forward, and template shortcuts while preserving comma-separated and JSON-array inputs.

  • Parse repeated recipient, attachment, removal, and inline values in order.
  • Validate every inline occurrence before performing side effects.
  • Cover compatibility and failure cases with shared tests.
  • Update command help and mail skill examples for both forms.

Summary by CodeRabbit

  • New Features

    • Mail commands now support comma-separated recipient and attachment lists, while retaining repeated flags.
    • Inline content accepts JSON objects or arrays per occurrence and preserves input order without comma-splitting.
  • Bug Fixes

    • Invalid inline values, including empty, whitespace-only, null, scalar, or empty objects, are rejected with clearer occurrence-specific errors.
    • Corrected inline validation error indexing.
  • Documentation

    • Updated mail command help and reference documentation to describe supported list and inline value formats.

📝 Walkthrough

Walkthrough

Mail shortcuts now validate repeated --inline values with occurrence-specific errors. Flag descriptions and reference pages document repeated or comma-separated recipient and attachment inputs, plus JSON object or array support for inline values. Tests cover these behaviors across mail shortcuts.

Changes

Mail repeatable input handling

Layer / File(s) Summary
Inline validation and coverage
shortcuts/mail/helpers.go, shortcuts/mail/mail_repeatable_flags_test.go
Inline values now reject empty, whitespace, null, scalar, and empty-object occurrences with indexed validation errors. Tests cover valid arrays, repeated string flags, and invalid later occurrences before execution.
Shortcut flag descriptions

Shortcut descriptions document repeated or comma-separated recipient and attachment values, attachment order, and unsplit inline JSON objects or arrays.
Mail reference documentation
skills/lark-mail/references/*
Reference pages document repeated flags, comma-separated lists, ordered merging, inline JSON object or array values, and updated attachment behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Suggested reviewers: liangshuo-1, xzcong0820

Merge Risk: 🟡 Moderate · up to b76be

The mail shortcut input changes are not ready to merge because the current code fails lint, template documentation omits important inline-image constraints, and tests do not directly prove error-cause preservation or that invalid values prevent execution.

Remove the forbidden bare errors.

Lines 2313 and 2317 use errors.New. The lint gate rejects both calls, so CI cannot pass. Use the project error mechanism, or add the required documented //nolint:forbidigo annotation for these preserved intermediate causes.

Also applies to: 2317-2317

Assert cause preservation for invalid inline values.

The test checks typed metadata and error text, but it does not check errors.Unwrap(err). A regression that removes .WithCause(err) still passes. Assert that the validation error preserves a non-nil cause.

Prove that validation stops execution.

This test only checks the returned validation error. It also passes if normalizeInlineFlagValues runs from Execute, because each shortcut normalizes the flag there too. Add a request, file-I/O, or Execute-call assertion that remains zero when occurrence 2 is invalid.

Restore manual inline mapping constraints.

These rows remove the requirements that file_path is relative and each CID is unique. Users can then provide values that validation rejects or that produce ambiguous inline references.

  • skills/lark-mail/references/lark-mail-template-create.md#L59-L59: State that file_path must be relative and CID values must be unique.
  • skills/lark-mail/references/lark-mail-template-update.md#L76-L76: State that file_path must be relative and CID values must be unique.

As per coding guidelines, preserve established CLI behavior and public APIs unless a breaking change is explicitly requested.
