Gav Verma 57f8158608 chore: improve skills render section (#8459)
This change improves the skills render section
- Separate the skills list from usage rules with clear subheadings
- Define skill more clearly upfront
- Remove confusing trigger/discovery wording and make reference-following guidance more actionable

r###"- Discovery: The list above is the skills available in this session (name + description + file path). Skill bodies live on disk at the listed paths.
- Trigger rules: If the user names a skill (with `$SkillName` or plain text) OR the task clearly matches a skill's description shown above, you must use that skill for that turn. Multiple mentions mean use them all. Do not carry skills across turns unless re-mentioned.
- Missing/blocked: If a named skill isn't in the list or the path can't be read, say so briefly and continue with the best fallback.
- How to use a skill (progressive disclosure):
1) After deciding to use a skill, open its `SKILL.md`. Read only enough to follow the workflow.
2) If `SKILL.md` points to extra folders such as `references/`, load only the specific files needed for the request; don't bulk-load everything.
3) If `scripts/` exist, prefer running or patching them instead of retyping large code blocks.
4) If `assets/` or templates exist, reuse them instead of recreating from scratch.
- Coordination and sequencing:
- If multiple skills apply, choose the minimal set that covers the request and state the order you'll use them.
- Announce which skill(s) you're using and why (one short line). If you skip an obvious skill, say why.
- Context hygiene:
- Keep context small: summarize long sections instead of pasting them; only load extra files when needed.
- Avoid deep reference-chasing: prefer opening only files directly linked from `SKILL.md` unless you're blocked.
- When variants exist (frameworks, providers, domains), pick only the relevant reference file(s) and note that choice.
- Safety and fallback: If a skill can't be applied cleanly (missing files, unclear instructions), state the issue, pick the next-best approach, and continue."###
