The `description` and `when_to_use` frontmatter fields of every available
`SKILL.md` are loaded into the Claude Code system prompt at the start of every
turn so it can route to the right skill; the body of each skill only loads on
invocation. So frontmatter is the lever for steady-state context cost.
Trims `maintainer-review`, `pr-triage`, and `pr-stats` to keep only what's
useful for routing — what the skill does, how it picks its targets where that
matters (`maintainer-review`'s "my reviews" working list, `pr-triage`'s `ready
for maintainer review` label), and the trigger phrases. Drops file-path
cross-refs, mutation names, "successor to breeze X" history, and verbose action
enumerations — all still present in the SKILL.md bodies, which are unchanged.
Saves roughly 500 tokens off the available-skills listing loaded each turn:
```
maintainer-review: ~420 → ~170 tokens
pr-triage: ~300 → ~125 tokens
pr-stats: ~170 → ~105 tokens
```
The `maintainer-review` skill was spitting out an warning before as well in
`/doctor`:
```
Some skill descriptions will be shortened
1 description exceeds the per-entry cap: maintainer-review
```
