Claude Code Skills Marketplace is a collection and marketplace of skills, plugins, agents, and instructions that extend Claude Code with specialized development workflows. It is for developers who want to install existing workflows or create, validate, and package their own Claude Code skills.
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 | $0.00144 | $0.03103 |
| Opus 5.5 | $0.00058 | $0.01241 |
| Sonnet 5.5 | $0.00029 | $0.00621 |
| Haiku 4.5 | $0.00014 | $0.00310 |
Grade A, and why
ghostty-use 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 today.
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.
How it starts
The opening of the file, as written. The whole thing — 225 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ghostty-use
Capture identifiable Claude Code and Codex terminal sessions before a reboot and reopen recorded IDs afterwards. Manual snapshots grade liveness; automatic backups store recovery metadata with explicit partial coverage and unknown liveness.
Ghostty on macOS has no session-restoration CLI or AppleScript tab dictionary (verified
on Ghostty 1.3.1, 2026-10-04), so this skill walks a practical loop around that limit:
manual ps inventory → liveness-graded snapshot → keystroke-paste restore →
automatic reconciliation that makes every paste failure visible.
Snapshot, reconstruction, dry-run and reconciliation can proceed without taking the desktop. Actual restore uses global keyboard/clipboard input and is foreground work even when launched as a background shell job. Before restore, use a concrete Ghostty handoff or existing explicit idle-desktop permission; check current activity and coordinate exclusive agent ownership. Under that standing grant, notify and execute without asking again. Idle input alone is not ownership. If busy/unknown, continue preparation and read-only checks; stop input on human takeover and never restore your old focus. Host denials remain binding.
Entry decision tree
| You just said / want | Run |
|---|---|
| Quitting for an update / reboot ("重启前保存会话") | snapshot |
| Periodic backup, save only changes ("定期增量快照") | Read automatic-snapshots.md, then ghostty_watch.py install --apply |
| Rebooted, want tabs back ("恢复之前的窗口") | Use a suitable snapshot; if absent or outdated, reconstruct, then restore --all on the selected manifest |
| "Was anything lost?" / suspicion after restore | check |
| One specific session to bring back | restore --only <id-prefix> |
| Codex quota running out; manually switching account, keeping all Codex work | Read codex-account-switch.md; switch-prepare → manual exit/login → switch-restore |
Codex account switch
Preserve all Ghostty Codex sessions before the user manually switches ChatGPT
accounts, then reopen the original session IDs in one batch. Exclude Claude Code.
Read codex-account-switch.md before this route.
Use scripts/ghostty_session.py switch-prepare and switch-restore; the bundled
scripts/ghostty_switch.py owns fixed-manifest selection, account/process checks,
duplicate-safe retries and separate authentication reporting.
What ships with it

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.

ghostty-use is a skill published in the GitHub repository daymade/claude-code-skills (1,473 stars, last pushed today), licensed MIT. It adds 144 tokens to every session and 3,103 once invoked, about $0.0006 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 2026-10-05.
