ADFA-6281 | Share AI prompt template engine and pane helpers - #2087
Conversation
Host-side template engine, generic YAML config loader/store and UI
helpers, consumed by AI-Core and the Gemini, Local, OpenAI and MCP
agents in plugin-examples. ABI-additive.
Prompt config:
- Include paths refuse a backslash and ':', which a Windows host would read as a separator or a drive.
- Any IOException from a source is reported as a PromptConfigException naming the file.
- Duplicate keys are refused explicitly; already SnakeYAML Engine's default, stated so an upgrade cannot flip it.
- Config text keeps its whitespace as YAML parsed it, so `|` keeps its final newline and `|-` drops it.
- PromptConfigStore treats a load that completed with an exception as failed: preload() retries it and configIfLoaded() returns null rather than calling getCompleted().
Template engine:
- Names may be in any case and hold dots ({{fileName}}, {{item.name}}), looked up as the whole key.
Pane helpers:
- SecretRevealController keeps the user's selection across a toggle, does not report legibility from attach(), is @mainthread, and waits for the redraw via postOnAnimation.
- applyPaneStyling does not recurse into a styled control's children.

Reviewed at 36898d2.
MINOR
- PLUGIN_API_CHANGELOG.md:66 - floors at 26.40, which already shipped without these classes
- PromptTemplateEngine.kt:16 - a padded tag like
{{ NAME }}passes through instead of throwing - PaneStyling.kt:111 - a plain-colour stroke recolours only the focused outline
- SecretRevealController.kt:70 - attach() leaves a revealed secret legible (answered in CodeRabbit's thread)
NITPICK - 1 inline, not listed
Prior round: CodeRabbit's SecretRevealController.kt:70 finding is still open at head (attach() still ends with render()). Graded MINOR, since no caller reuses a controller, and answered in its thread.
REVIEW.md asks blocking comments to name a concrete risk, and CLAUDE.md gates QA on no critical, high or medium findings. Neither sets an approve/request-changes rule, so the default applied: with nothing above MINOR this review is COMMENT.
…elpers Accept padded tags and reject malformed ones, re-mask on reattach, floor changelog at 26.41.
…capability Backends implement canSearchWeb() so ai-core offers web_search only when a search would run.

MINOR
- LlmInferenceService.java:782 -
WebSearchBackendmissing from the class Javadoc's capability list - PromptTemplateEngine.kt:20 - no escape for a literal
{{namein config text - SecretRevealController.kt:70 - the
onLegibleChangedKDoc still saysattach()never calls it - PromptConfigStore.kt:64 (CodeRabbit's thread) - a throwing
reloadcallback crashes the process - PR description (below) - still says 26.40, omits the new APIs, no Jira link first
Previous round, checked against the code at 5bed37e:
- MINOR PLUGIN_API_CHANGELOG.md:66 - fixed: 26.40 marked released, entries under
26.41 — unreleased, floor 26.41. - MINOR PromptTemplateEngine.kt:16 - fixed:
TAGaccepts padding andMALFORMEDrefuses leftover{{name. - MINOR PaneStyling.kt:112 - fixed by documenting that
FieldColors.strokemust be a selector. - NITPICK PromptTemplateEngine.kt:176 - fixed: the guard is gone.
- MINOR SecretRevealController.kt:70 (CodeRabbit's thread) - fixed:
attach()ends withif (isRevealed) mask() else render().
Findings without a diff anchor:
MINOR: The PR description still says these classes are "part of the 26.40 release" and to floor plugin.min_ide_version at 26.40, while this PR's changelog now files them under 26.41; 26.40 shipped without them. It also does not mention WebSearchBackend or PromptConfigStore.reload, both public ABI added since the first round, and it opens with ## Description instead of the Jira link CoGo's CLAUDE.md asks for first. A plugin author following it floors at 26.40 and hits NoClassDefFoundError. Update the floor, list the two APIs, and put the ADFA-6281 link on the first line.
REVIEW.md asks blocking comments to name a concrete risk and CLAUDE.md gates QA on no critical, high or medium findings; neither sets an approve/request-changes rule, so the default applied: with nothing above MINOR this review is COMMENT.

Approving: every earlier finding is fixed, and what remains is MINOR (the WebSearchBackend Javadoc, a literal-brace escape, the onLegibleChanged KDoc, the reload callback guard, and the PR description). Worth addressing, not blocking.
