Summary

Add a command-scoped --concise option to IM chat and thread message lists. It renders compact Markdown for agent context without changing the generic --format pipeline or existing message conversion and enrichment behavior.

Changes

  • Add --concise only to im +chat-messages-list and im +threads-messages-list.
  • Render chat/thread metadata, participants, messages and replies, reactions, downloaded resource paths, and pagination state as Markdown.
  • Use ChatSections as the renderer input so future IM message commands can provide their own section boundaries.
  • Omit message_app_link and other nonessential fields from concise output; JSON remains available for the complete data shape.
  • Keep JSON, pretty, table, CSV, NDJSON, dry-run, pagination, conversion, and enrichment paths unchanged.
  • Keep --format concise on the existing unknown-format path: warning, JSON fallback, and exit code 0.
  • Reject --concise combined with explicit --format, enabled --json, or non-empty --jq; allow --json=false and --jq=.
  • Scan the actual concise renderer view with the existing content-safety policy before writing output.
  • Add concise examples to the two command references without changing Skill routing.

Test Plan

  • go test ./cmd ./shortcuts/im
  • make unit-test
  • make vet
  • make fmt-check
  • node scripts/skill-format-check/index.js
  • make build
  • go mod tidy leaves go.mod and go.sum unchanged
  • QUALITY_GATE_CHANGED_FROM=origin/main make quality-gate (existing warnings only)
  • Real user-identity tests from the SCM-built binary: chat/thread concise output, topic replies, empty results, pagination, resource downloads, reaction opt-out, dry-run, legacy formats, unknown-format fallback, and all output-flag conflicts

📝 Walkthrough

Walkthrough

The PR adds a command-scoped concise format for IM chat and thread message listings. It adds Markdown rendering, pagination handling, format registration, compatibility tests, and updated IM guidance.

Changes

Concise IM output

Layer / File(s) Summary
Concise emission contract
internal/output/emitter.go, internal/output/emitter_contract_test.go, internal/cmdutil/dryrun_test.go
SuccessWithConcise invokes a command renderer for exact lowercase concise output. Other cases retain generic fallback behavior.
Command-scoped format registration
shortcuts/common/runner.go, shortcuts/common/runner_flag_completion_test.go, shortcuts/common/runner_validation_test.go
Shortcuts can register additional formats for usage text and shell completion. Format values remain unchanged at runtime.
IM concise renderer
shortcuts/im/message_concise.go
The renderer produces sanitized Markdown with message metadata, participants, replies, reactions, resources, errors, and pagination state.
Message-list integration
shortcuts/im/im_chat_messages_list.go, shortcuts/im/im_threads_messages_list.go
Chat and thread message-list commands register concise and route output through the new renderer.
Renderer and pagination validation
shortcuts/im/message_concise_test.go, shortcuts/im/im_list_page_all_test.go
Tests cover rendering, escaping, fallback formats, command isolation, mounted execution, and completed or incomplete pagination.
IM usage guidance
affordance/im.md, internal/affordance/im_source_test.go, skills/lark-im/references/*
Guidance documents concise Markdown output, inline thread expansion, known-thread retrieval, and continuation conditions.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 68c6d

The PR adds opt-in concise Markdown output for two IM message-list commands while preserving existing formats and fallback behavior. It is mergeable with owner awareness: documentation should clarify that output may be limited to the fetched page, and the typed-error contract test should be strengthened to prevent regressions.

Review conclusion: no merge-blocking functional or compatibility issue found. Concise is scoped to im +chat-messages-list and im +threads-messages-list through command-local help/completion and rendering. Existing JSON, pretty, table, CSV, NDJSON, unknown-format JSON fallback, --json, --jq conflict handling, pagination, and dry-run behavior remain covered by regression tests. One intentional historical behavior change exists in the shared thread expansion path: a thread omitted after the total reply budget is exhausted now receives thread_has_more=true. This is an additive optional JSON field and can also appear in +messages-mget because it shares the same expansion helper; no existing field is removed or retyped. Focused tests, race tests, affordance/schema tests, skill format validation, diff checks, and the latest CI run pass. The existing CodeRabbit inline note about asserting typed error metadata is valid but test-quality-only and non-blocking.

Correction / requirement blocker: after comparing this PR with #2540 and the stated two-option requirement, #2567 still implements option 1 (a new command parameter/output mode). The new behavior is entered only through --format concise, while the existing/default JSON and pretty outputs are intentionally preserved. Therefore, if this replacement PR was opened to implement option 2 (simplify the existing output itself instead of adding a separate concise mode), the functional requirement is not met and this is merge-blocking. Compatibility within the implemented option-1 design remains sound; the problem is requirement alignment, not a runtime regression. Please clarify or rework the target output contract before merge.

In `@shortcuts/im/message_concise_test.go`:
- Around line 357-360: Update the “jq rejects concise” test around

err.Error(). Preserve the existing scenario and ensure the assertions validate
the jq/concise conflict contract directly.

In `@shortcuts/im/message_concise.go`:
- Around line 122-124: Update renderConciseMessage to read message_app_link,
sanitize it using the existing AppLink rendering helpers, and append the
resulting safe AppLink to the concise output alongside message_id. Update the
related concise-message test to assert the rendered AppLink rather than
rejecting it.
