Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00045 | $0.00443 |
| Opus 5 | $0.00023 | $0.00221 |
| Sonnet 5 | $0.00009 | $0.00089 |
| Haiku 4.5 | $0.00005 | $0.00044 |
Grade A, and why
glyphs-mcp-kerning scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
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_bumperbefore any apply step. - Always run
apply_kerning_bumperwithdry_run=truebefore a mutating call. - Only mutate after explicit user approval and with
confirm=true. - Never auto-save the font.
Workflow
- Read current state with the smallest useful set of tools:
get_selected_font_and_masterget_selected_glyphsget_font_kerningorget_glyph_detailsonly if the review needs extra context
- Run
review_kerning_bumperand summarize:- affected glyphs or pairs
- collision or near-miss findings
- proposed adjustments
- If the user wants to proceed, run
apply_kerning_bumperwithdry_run=true. - Report what would change, including changed and skipped counts if available.
- Only after explicit approval, run the real apply call with
confirm=true. - Re-read or summarize the affected state and clearly separate:
- what changed
- what was skipped
- anything still needing manual review

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
