# Glyphs MCP kerning

Use this skill for guarded kerning bumper workflows.

## Core rules

- Review calls remain non-mutating; confirmed apply calls remain explicitly
  approval-gated font edits.
- Read current state before mutation.
- Run `review_kerning_bumper` before any apply step.
- Always run `apply_kerning_bumper` with `dry_run=true` before a mutating call.
- Only mutate after explicit user approval and with `confirm=true`.
- Never auto-save the font.

## Workflow

1. Read current state with the smallest useful set of tools:
   - `get_selected_font_and_master`
   - `get_selected_glyphs`
   - `get_font_kerning` or `get_glyph_details` only if the review needs extra context
2. Run `review_kerning_bumper` and summarize:
   - affected glyphs or pairs
   - collision or near-miss findings
   - proposed adjustments
3. If the user wants to proceed, run `apply_kerning_bumper` with `dry_run=true`.
4. Report what would change, including changed and skipped counts if available.
5. Only after explicit approval, run the real apply call with `confirm=true`.
6. Re-read or summarize the affected state and clearly separate:
   - what changed
   - what was skipped
   - anything still needing manual review
