System and mode prompts referenced tools that may be absent from the
session catalog, forcing the model to satisfy requirements it cannot
execute (generalizes #8139's browser-verification mismatch):
- system-prompt.md: browser verification now keys on the actual UI
surface and available tools (browser/computer/TUI/CLI), with an
explicit behavioral/smoke-test fallback when no runtime tool exists;
todo workflow guidance and the AST-section grep hint are gated on
tool presence; the auto-QA report_issue block additionally requires
the write tool.
- project-prompt.md: workspace-tree drill-in and additional-roots tool
hints only name tools present in the session.
- plan-mode-active.md: ask-tool directives get a prose fallback and
scout-via-task dispatch is gated on the task tool (render site now
passes askAvailable/taskAvailable).
- orchestrate-notice.md: the tool budget, verify gates, todo tracking,
and inline-edit guidance are gated on tool presence; the notice is
skipped entirely when the task tool is inactive (render fn takes the
active tool list).
Adds regression tests for each gate; changelog entry.
Magic keyword matching now treats sentence punctuation and quotes as prose boundaries while still rejecting casing changes, inflections, and path/file-extension occurrences.
Added regression coverage for detection and highlighting across ultrathink, orchestrate, and workflowz.
Fixes#4965
- Added `highlightMagicKeywords(text: string, resetTo?: string): string` and chained ultrathink, orchestrate, workflow glow.
- Updated ultrathink, orchestrate, and workflow matching to lowercase whitespace-delimited patterns with prose-only checks.
- Added `maskNonProse` and `keywordInProse` to skip fenced/inline code and HTML/XML segments while highlighting keywords.
- Added `KeywordHighlighter` with optional `resetTo`, and updated gradient highlighting to use masked match slicing.
- Added orchestrate keyword detection and notice handling for non-synthetic prompts.
- Added orchestrate notice handling in session output paths, including streaming and append delivery.
- Added a system orchestrate notice specifying task-subagent delegation, phase workflow, and validation gates.
- Added shared gradient-highlighter utilities and switched ultrathink highlighting to use cached palettes.
- Removed embedded orchestrate prompt artifacts and updated usage tips for orchestration, ultrathink, and /login behavior.
