* feat: add size caps for PR diff, fetch_url, Slack threads, pagination, message queue
Per-source byte/token caps with explicit truncation markers to prevent
unbounded payloads from blowing up LLM context/memory.
- reviewer_diff.py: cap PR diff at 200K chars with head+tail truncation
- fetch_url.py: cap markdownify output at 100K chars
- slack.py: cap thread message fetch at 500 messages
- github_comments.py: cap _fetch_paginated at 50 pages
- thread_ops.py: cap queued messages at 100 (drop oldest)
Closes OPE-51

* fix: compute diff line set from full diff, keep most recent Slack messages
Address PR review comments:
1. Truncated diffs rejected valid findings: fetch_pr_diff now returns the
full diff; truncate_diff is called separately in reviewer.py so the
line set used for add_finding/publish_review validation is computed
from the complete diff, not the truncated prompt text.
2. Slack cap dropped recent thread context: fetch_slack_thread_messages
now keeps the most recent SLACK_THREAD_MAX_MESSAGES messages (was
keeping the oldest). The tool surfaces a truncation marker in the
formatted output so the LLM knows the thread was truncated.

* feat: link Slack thread/Linear ticket in PRs and append ticket to title
When opening PRs, include any referenced Slack thread or Linear ticket
in the description and append the resolvable ticket number to the title.
Adds a Slack permalink to the webhook prompt so the agent has a
ready-to-link thread URL.

* feat: deterministically append source refs to private-repo PRs only
Move the Slack/Linear source-reference linking out of the prompt and into
open_pull_request, gated to private repos so private Slack thread URLs and
Linear identifiers are never published to a public PR. Reverts the prompt
instruction and webhook permalink injection in favor of this server-side append.

Add conversations.info fetch so a repo:owner/name (or GitHub URL) token
in a Slack channel's topic/purpose pins the channel to a repo, slotting
in just below thread metadata in get_slack_repo_config.

* feat(reviewer): surface dashboard UI link on PR reviews [INF-0000]
Post a transient "review in progress" comment (with an "Open in Web"
dashboard link) when a reviewer run starts, then delete it once the
review lands. The published review body now carries the same
"Open in Web" link, so the link persists on the review itself.
The transient comment's id is tracked in reviewer thread metadata
(status_comment_id) so it can be deleted on completion.
* refactor(reviewer): inline dashboard URL helper, drop redundant future import [INF-0000]
Open SWE Review now runs from automated PR triggers, so drop the old Slack/GitHub review keyword entrypoints and keep PR comments on the regular agent path.

* fix: propagate Slack reply errors
Co-authored-by: Johannes du Plessis <51395795+johannes117@users.noreply.github.com>
* fix: classify Slack 429 as rate_limited with retry-after
Slack chat.postMessage rate limiting returns HTTP 429, which raise_for_status
turned into a generic http_error and told the agent to retry immediately,
ignoring Slack's retry window. Special-case 429 (threading Retry-After) and
normalize the ratelimited body code before the generic HTTP path so the
existing rate_limited hint actually fires.

* feat: add 10 more tips to the trace-reply rotation
The TRACE_REPLY_TIPS pool only had 9 tips, so users mostly saw the same
ones. Added 10 more grounded in actual features (review command, image
attachments, GitHub-issue triggers, persistent sandboxes, OAuth fallback,
etc.) so the rotation surfaces more of what open-swe can actually do.

* swap out 3 tips per review feedback
Replaced the suggestion-blocks, sandbox-auto-recovery, and OAuth-fallback
tips with three more practically useful ones: cross-posted Slack message
resolution, the web_search tool, and the Linear ticket-management tools.

Appending "Please react with 👍 or 👎..." to every Slack completion
message ended up being repetitive noise. Drop the prompt-side instruction
and add the same ask as one of the rotating tips on the trace reply, so
users still see it occasionally without it cluttering each final summary.
Now that assistant.threads.setStatus carries the "is thinking…"
indicator, the per-run greeting phrase + auto-unfurl on the LangSmith
link are just visual noise stacking on top of it. The trace reply now
posts only `<url|View trace>` + a tip, with link unfurling off so the
smith.langchain.com card no longer appears.
Adds an `unfurl_links`/`unfurl_media` knob to post_slack_thread_reply_with_ts
(default-on to preserve behaviour for every other caller).
* feat: add Slack reaction feedback to LangSmith
Record Slack reaction feedback against explicitly mapped LangGraph runs so user ratings are idempotent and tied to the message they reacted to.
* Address review feedback on Slack reaction → LangSmith feedback
- langsmith.py: drop lru_cache on _build_langsmith_feedback_clients so
rotated keys / late env hydration are picked up; dedupe by (key, url)
tuple instead of key alone so the same key pointing at different
endpoints (cloud + self-hosted) builds both clients.
- langsmith.py: treat LangSmithNotFoundError on delete_feedback as
success — out-of-order or redelivered reaction_removed events would
otherwise loop forever on Slack's retry policy.
- slack_feedback.py: include channel_id in _feedback_key so the same
message_ts in two channels can't collide on the same feedback id.
- slack_feedback.py: treat conflicting +/- reactions from one user as
ambiguous (clear feedback) instead of averaging to a misleading 0.5.
- slack_feedback.py + slack.py + webapp.py: gate reaction handling to
the user who triggered the run (stored in the slack_run_map mapping
alongside run_id). Prevents bystanders in shared channels from
polluting eval feedback.
* feat: add optional Slack Assistants API typing status indicator
Mirrors OpenClaw's pragmatic approach: instead of rebuilding around
assistant_thread_started events, just opt into assistants.threads.setStatus
to show 'is thinking…' while the agent is working, and clear it when
post_slack_thread_reply lands. Gated behind SLACK_ASSISTANTS_API_ENABLED so
it can be toggled without touching code.
* fix(slack): drop redundant clear, add status heartbeat across model calls
- Slack auto-clears the typing indicator on bot post; remove the explicit
assistants.threads.setStatus("") call from post_slack_thread_reply.
- The indicator expires after ~2 minutes; add a before_model middleware
that refreshes it on every model tick so it stays visible across long
agent runs. Reuses the existing slack_thread.{channel_id,thread_ts}
configurable already plumbed for notify_step_limit.
- chat:write is sufficient on the bot token (assistant:write is on the
way out per Slack docs); no scope or app-config change required.
* feat(slack): contextual status text + rotating loading_messages
- set_slack_assistant_status now accepts an optional loading_messages list
(capped at 10 per Slack's API), surfaced via the assistants.threads.setStatus
payload so Slack rotates through them client-side.
- The heartbeat middleware derives a contextual status from the last
assistant message's tool calls (e.g. "searching the codebase…" after
grep, "running commands…" after execute), falling back to the default
"is thinking…" when no tool calls or unknown tool name.
- Adds a curated DEFAULT_LOADING_MESSAGES list passed alongside the
contextual status on each refresh.

* feat: only post Slack 'Working on it!' on first thread mention
* feat: randomize Slack trace reply phrase
Pick from a small list of friendly phrases instead of always saying
'Working on it!' so the bot feels less robotic. Explicit messages (e.g.
'Taking a look...' from PR review path) are unaffected.

The agent sees users formatted as @Name(USER_ID) in conversation context and
reproduces that pattern in replies, but Slack requires <@USER_ID> for real
mentions. This adds automatic conversion and updates prompt instructions.
