Issue for this PR

Closes #17820

Type of change

  • Bug fix
  • New feature
  • Refactor / code improvement
  • Documentation

What does this PR do?

Applies the experimental.chat.messages.transform hook during compaction before messages are converted for the model.

How did you verify your code works?

Reproduced the issue with a plugin using experimental.chat.messages.transform:

  1. Send a normal prompt and confirm the hook modifies it
  2. Trigger /compact
  3. Confirm the same message changes are now applied during compaction too

Screenshots / recordings

N/A - no UI changes.

Checklist

  • I have tested my changes locally
  • I have not included unrelated changes in this PR

Keep compaction summaries aligned with the main prompt path so plugins see the same transformed messages in both flows.

note: We will cleanup these experimental hooks and make a cleaner interface for plugins soon. This is a temporary "hack" to fix an issue.

* fix(vcs): fix inverted HEAD filter in watcher (backport B8 #17829)

The file watcher was ignoring HEAD changes instead of filtering
non-HEAD changes, so branch switches were never detected.

* fix(core): detect context_length_exceeded in API call errors (backport B1 #17748)

Parse response body for error code so providers returning
context_length_exceeded are correctly classified as context overflow.

Upstream: anomalyco/opencode#17748 (e718db6)

* fix(util): log ZodError issues on schema validation failure (backport B5)

Print the specific validation issues alongside the stack trace to make
debugging schema mismatches easier.

* fix(tui): check for selected text in dialog escape handler (backport B7 #16779)

Check getSelectedText() instead of just getSelection() so escape
correctly closes dialogs when a selection object exists but has no text.

Upstream: anomalyco/opencode#16779 (a64f604)

* fix(ui): wrap question option descriptions instead of truncating (backport B6 #17782)

Replace overflow:hidden/text-overflow:ellipsis with overflow-wrap:anywhere
so long descriptions are visible. Remove the now-redundant data-custom override.

Upstream: anomalyco/opencode#17782 (51fcd04)

* fix(opencode): apply message transforms during compaction (backport B2 #17823)

Run Plugin.trigger("experimental.chat.messages.transform") on a
structuredClone of messages before passing them to the compaction model.

Upstream: anomalyco/opencode#17823 (4cb2996)

* fix(opencode): forward session permission ruleset to LLM stream (backport B3 #17064)

Add permission field to StreamInput and merge it with agent permissions
when computing disabled tools. Forward session.permission from prompt.ts.

Upstream: anomalyco/opencode#17064 (c2ca149)

* fix(opencode): add prompt schema validation debug logs (backport B4 #17812)

Log info and part schema validation failures before persisting to help
diagnose data corruption issues.
