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 | $0.00000 | $0.00444 |
| Opus 5 | $0.00000 | $0.00222 |
| Sonnet 5 | $0.00000 | $0.00089 |
| Haiku 4.5 | $0.00000 | $0.00044 |
Grade A, and why
gum-plugin-install 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 4d 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
gum plugin install
Generated from
gum schema --json. Do not edit this page by hand; runmake docs-commands.
Installs a plugin through an atomic registry update: validates the manifest, runs the namespace-ownership check against the active profile's plugins.lock, and writes plugin-catalog.json + plugins.lock + plugin-state.json through one fsync'd transaction.
Plugins are third-party subprocesses. Installing one trusts its executable and manifest-declared capabilities; plugin-managed auth means the plugin, not GUM's OAuth resolver, is responsible for any credentials it requests or forwards. Review the source and manifest, then pass --yes to acknowledge that trust.
Use --dev-allow-namespace-conflict on a dev profile (set profile.is_dev=true via gum config set) to install a plugin whose prefix collides with an existing namespace_owner. Outside a dev profile the flag is ignored and the install fails with PLUGIN_NAMESPACE_CONFLICT.

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.
