* fix(frontend): truncate overflowing text in agent cards
Long custom agent names, descriptions, skills and tool-group labels
overflowed the agent card and broke its layout (issue #3389). The title
already had `truncate`, but it never took effect: an ancestor flex
container lacked `min-w-0`, so the flex item refused to shrink below its
content width.
- Restore the truncation chain by adding `min-w-0` to the title's flex
ancestors so `truncate` can finally take effect.
- Cap and ellipsize model / skill / tool-group badges via a small
`TruncatedBadge` (`block max-w-full truncate`).
- Reveal the full value on hover, but only when the text is actually
clipped (`TruncatedTooltip`, width + height detection), so names,
descriptions and labels stay readable without popping redundant
tooltips on short cards.
* fix(frontend): wrap unbreakable strings in agent card tooltips
A long token with no break opportunity (no spaces or hyphens) could still
overflow the tooltip horizontally. Add `break-words` next to the existing
`text-wrap` so such strings wrap instead of overflowing.
Addresses Copilot review feedback on tooltip wrapping robustness.
* fix(frontend): show agent card tooltips instantly
Drop the explicit `delayDuration` so card tooltips fall back to the
provider's default 0ms delay. Instant feedback is better UX for revealing
text that is already clipped, per maintainer review.

* feat(subagents): support per-subagent skill loading and custom subagent types (#2230)
Add per-subagent skill configuration and custom subagent type registration,
aligned with Codex's role-based config layering and per-session skill injection.
Backend:
- SubagentConfig gains `skills` field (None=all, []=none, list=whitelist)
- New CustomSubagentConfig for user-defined subagent types in config.yaml
- SubagentsAppConfig gains `custom_agents` section and `get_skills_for()`
- Registry resolves custom agents with three-layer config precedence
- SubagentExecutor loads skills per-session as conversation items (Codex pattern)
- task_tool no longer appends skills to system_prompt
- Lead agent system prompt dynamically lists all registered subagent types
- setup_agent tool accepts optional skills parameter
- Gateway agents API transparently passes skills in CRUD operations
Frontend:
- Agent/CreateAgentRequest/UpdateAgentRequest types include skills field
- Agent card displays skills as badges alongside tool_groups
Config:
- config.example.yaml documents custom_agents and per-agent skills override
Tests:
- 40 new tests covering all skill config, custom agents, and registry logic
- Existing tests updated for new get_skills_prompt_section signature
Closes#2230
* fix: address review feedback on skills PR
- Remove stale get_skills_prompt_section monkeypatches from test_task_tool_core_logic.py
(task_tool no longer imports this function after skill injection moved to executor)
- Add key prefixes (tg:/sk:) to agent-card badges to prevent React key collisions
between tool_groups and skills
* fix(ci): resolve lint and test failures
- Format agent-card.tsx with prettier (lint-frontend)
- Remove stale "Skills Appendix" system_prompt assertion — skills are now
loaded per-session by SubagentExecutor, not appended to system_prompt
* fix(ci): sort imports in test_subagent_skills_config.py (ruff I001)
* fix(ci): use nullish coalescing in agent-card badge condition (eslint)
* fix: address review feedback on skills PR
- Use model_fields_set in AgentUpdateRequest to distinguish "field omitted"
from "explicitly set to null" — fixes skills=None ambiguity where None
means "inherit all" but was treated as "don't change"
- Move lazy import of get_subagent_config outside loop in
_build_available_subagents_description to avoid repeated import overhead
