Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00020 | $0.00478 |
| Opus 5.5 | $0.00008 | $0.00191 |
| Sonnet 5.5 | $0.00004 | $0.00096 |
| Haiku 4.5 | $0.00002 | $0.00048 |
Grade A, and why
scan-font-sources 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 17d 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
Scan font sources
Refresh ~/.claude/local-font-sources/index.json against the current
state of every source in ~/.claude/local-font-sources/config.json. Read
${CLAUDE_PLUGIN_ROOT}/skills/scan-font-sources/references/scanning.md and
follow it — this skill is the trigger, that file is the mechanics; do not
duplicate the procedure here.
Arguments (optional): $ARGUMENTS — <name> <path> to add or repoint a
single source in config.json before scanning (e.g. default /Users/allancole/Claude Projects/font-sources). Omit to scan every
configured source as-is.
Steps
- Resolve sources: apply
$ARGUMENTSif given, else readconfig.jsonas-is; if it's missing or still has the old single-key (font_dir) shape, migrate it to{"sources": [...]}in place. If there are no sources at all, ask once and write one nameddefault. - Refuse to scan any source path under
~/Library/Mobile Documents/(iCloud) or another live cloud-sync location — report that the collection needs to be copied to local disk first and stop, for that source only (other sources still scan). - Run the scan procedure from
${CLAUDE_PLUGIN_ROOT}/skills/scan-font-sources/ references/scanning.mdin full for every source: walk, parse, license-check, diff, updateindex.json, tagging each result with its source'sname. - Report the delta only, broken out per source if more than one — new files, files flagged for reclassification, files now missing on disk, and updated totals by license status. Do not print the full index.
This skill never classifies anything (no specimen rendering, no web
research) — it only updates index.json. Classification happens
on demand, through /find-font or through a real design task, per
${CLAUDE_PLUGIN_ROOT}/skills/find-font/references/classification.md.
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.

scan-font-sources is a skill published in the GitHub repository a8cteam51/claude-code-plugins (5 stars, last pushed 2d ago), licensed MIT. It adds 20 tokens to every session and 478 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-29.
