Add a per-platform `cron_continuable_surface` extra key
(`thread` default | `in_channel`) so a continuable cron job can deliver
FLAT into a Slack channel — no dedicated thread — and still be
replied-to. In `in_channel` mode the scheduler skips the thread-open
branch (leaves `thread_id=None`); the shipped origin-mirror then seeds
the `(slack, chat_id, None)` shared-channel session — the same bucket
`reply_in_thread: false` routes inbound channel replies to — so a plain
channel reply continues the job in context.
Design: specs/cron-inchannel-continuable (D1–D7, F5). Model B
(shared-channel session), NOT anchoring to the delivery `ts` — on Slack
replying to a specific message IS threading, so a `ts` anchor would only
relocate the thread, never deliver true threadless continuable.
- gateway/platforms/base.py: `supports_inchannel_continuable` capability
flag (default False → unsupported platforms fail SAFE to `thread`).
- plugins/platforms/slack/adapter.py: flag=True; `_cron_continuable_surface()`
resolver (coerces to the two-value enum); `_warn_if_inchannel_without_flat_reply`
connect-time warning (D5: warn, not hard-require — the misconfig fails safe).
- gateway/config.py: shared-key bridge line (top-level OR nested config).
- cron/scheduler.py: read the key generically from platform config, gate
the `in_channel` branch on the adapter capability flag, skip thread-open.
No new seed function (reuses the existing mirror — G6).
Pairing (docs): `in_channel` + `reply_in_thread: false` +
`require_mention: false` (or a free-response channel). Missing
`reply_in_thread: false` fails safe to a threaded continuation.
Gateway-side config flag — `/restart` to apply; NO Slack app reinstall.
Tests (from inside the worktree, PYTHONPATH=$PWD):
- +6 cron scheduler tests (in_channel skips thread-open; seeds flat
channel session with thread_id=None; thread-mode regression;
fail-safe on unsupported platform; value coercion). Prove-fail:
removing the `and not in_channel_surface` guard turns the two
load-bearing tests RED; restore → GREEN.
- +10 slack resolver/capability/warning tests; +2 config-bridge tests.
- tests/manual/cron_inchannel_e2e.py: offline E2E driving BOTH real
legs (delivery seed + inbound reply keying) → both converge on
(slack, C, None).
- No regressions: test_slack.py 216 passed alone; broader sweep green
(4 pre-existing cross-file-ordering failures reproduce identically on
pristine origin/main).
Docs: cron.md + slack.md + zh-Hans mirrors of both.
Replace the interim monospace table fallback with Slack's native `table`
block (rows of rich_text cells). Addresses the core ask in #18918.
- _table_block(): builds type:"table" with rich_text cells, so inline
formatting (bold, links, code) renders inside cells.
- Column alignment parsed from the markdown separator row (:---, :-:, --:)
into column_settings (left = default/null-skip, center/right emitted).
- Escaped pipes (\\|) are not treated as column separators.
- Respects Slack's table limits (100 rows / 20 cols / 10k aggregate chars);
oversized or unparseable tables gracefully fall back to aligned monospace
(rich_text_preformatted), so a big table never breaks the message.
Docs (EN + zh-Hans) updated to describe native tables + the fallback.
Tests: native table shape, alignment->column_settings, inline-formatted
cells, oversized/too-wide monospace fallback, escaped-pipe cell. Prove-
failed against a stubbed _table_block (native-table tests fail, fallback
tests stay green). All existing Slack tests still pass.
Add platforms.slack.extra.rich_blocks (default off). When enabled, the
final agent message is sent as Slack Block Kit blocks — section headers,
dividers, and true nested lists via rich_text — instead of flat mrkdwn.
- New plugins/platforms/slack/block_kit.py: pure markdown->blocks renderer
(headers, dividers, nested ordered/bullet lists, blockquotes, fenced code;
pipe-tables as aligned monospace since Block Kit has no robust table block).
Enforces Slack's 50-block / 3000-char section limits and returns None to
fall back to plain text on empty/oversized/unexpected input. Never raises.
- adapter.send(): render blocks on the single-chunk primary message; a
text= fallback is ALWAYS sent alongside (notifications/accessibility).
- adapter.edit_message(): blocks only on finalize=True, so intermediate
streaming edits stay plain mrkdwn (no per-flush block re-derivation).
- Docs (EN + zh-Hans) + config example. Send-side only: no app reinstall.
Tests: pure-renderer unit suite + adapter integration suite (blocks present
when on, plain text when off, text fallback always set, finalize gating,
multi-chunk fallback). Prove-failed against a stubbed renderer.
Follow-up to the group-DM manifest fix. The manifest change only helps
NEW installs; existing apps keep their old (mpim-less) scopes until the
admin reinstalls. Since a missing message.mpim event delivers nothing
(no runtime API error to catch), detect stale installs at connect time
from the auth.test x-oauth-scopes header and log an actionable reinstall
nudge when im:history is granted but mpim:history is not. Also promote
message.mpim from Recommended to Required in the docs event tables so the
default setup path can't drop it.
Group DMs (multi-person DMs, channel_type=mpim) were never delivered to
the Slack bot. The adapter already classifies mpim as a DM and replies
ambiently (adapter.py:2526, is_dm = channel_type in {im, mpim}), but the
generated app manifest only subscribed to message.im / im:history — the
1:1 DM pair. Without the message.mpim event subscription Slack drops
group-DM messages before the adapter ever sees them, so 1:1 DMs worked
while group-DM ambient mode was dead.
Add message.mpim to bot_events and mpim:history (the scope that event
requires per Slack docs) + mpim:read (mirrors im:read for the
conversations.info classification call) to bot_scopes. Update the
SLACK_BOT_TOKEN / SLACK_APP_TOKEN setup-help strings and the Slack docs
(EN + zh-Hans: scope table, event table, troubleshooting) so existing
installs are told to add the new scopes and reinstall.
Reported by an enterprise customer. Note: this is a manifest/scope
change, so it only takes effect after the app is reinstalled and the
new scopes are accepted.
Tests: assert message.mpim + mpim:history + mpim:read are in the
manifest (with and without assistant mode); both fail on current main
and pass with this change.
Translates the full English docs corpus (335 files) into Simplified
Chinese under website/i18n/zh-Hans/. Combined with PR #31895 (cross-
locale link fix), the 简体中文 locale toggle now serves a complete
Chinese site with working cross-page navigation.
Pipeline:
- Claude Sonnet 4.6 via OpenRouter, 8-way concurrent
- Preserves frontmatter keys, code blocks, MDX/JSX, link URLs, brand
names, and technical jargon (prompt/token/hook/MCP/ACP/etc.)
- Translates only frontmatter title/description and prose
- Two largest files (configuration.md 93KB, research-paper-writing.md
107KB) retried with 64K max_tokens after initial fence-drift
- 3 manual post-fixes for MDX edge cases the model didn't escape:
< in optional-skills-catalog table, double-quotes in an alt= tag,
and a bare URL adjacent to a full-width period
Cost: ~$30 total (Sonnet 4.6 input $3/M + output $15/M).
Verified `npm run build` succeeds for both en and zh-Hans locales,
no double-prefixed /docs/zh-Hans/docs/ URLs in rendered output,
all in-page navigation resolves correctly.
Translations are machine-generated and may need human review on
specific pages — but they're an enormous improvement over the
previous state (3 zh-Hans pages out of 335).
