gaia-verify

gaia-verify is a skill for Claude Code from metraton/gaia. It costs 33 tokens per session (2,337 once invoked), scanned B, original, MIT.

A verification procedure for checking whether a Gaia installation works on the way it was installed, such as through npm or a Claude Code plugin.

In plain words
What is it for?
Use it after installing or changing Gaia to test the relevant workspace or plugin setup.
Why use it?
It prevents an installation from being treated as healthy just because files are present. It runs checks suited to the installation surface and reports pass or fail.

Token cost

What it costs to keep this loaded

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.

Security

Grade B, and why

gaia-verify scanned grade B with 1 finding 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 yesterday.

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.

Gaia Verify

Confirm that a Gaia installation actually works. Given a workspace and a delivery surface, run the checks that match that surface and report PASS/FAIL. This skill owns the definition of "a healthy install" -- the wire-up checklist and the per-surface checks. It is the check that gaia-release calls at the close of every layer; here it stands alone so the user can invoke it directly against whatever they just installed.

Gaia ships as one tree reaching a workspace through two surfaces -- npm/pnpm (the npm package @jaguilar87/gaia: symlinks + settings.local.json) and the Claude Code plugin (source: github with a pinned ref -- .claude-plugin/marketplace.json advertises the plugin, so /plugin install makes CC clone the git repo into its plugin cache and load hooks from the repo root's hooks/hooks.json; the root .claude-plugin/plugin.json is metadata-only, and there is no dist/ bundle). A change can pass on one surface and break on the other, so the mode you pick must match the surface you are validating.

Decision tree

"probemos" / "verify" / "test installation"
├─ Already installed in a workspace (npm/pnpm), just edited source? -> live
├─ Proving the npm tarball before a release?                        -> npm-sandbox
├─ Proving the npm tarball as a plugin before a release?           -> plugin
└─ Confirming a version already published to npm?                   -> registry

If the user does not name a mode, ask: "Which mode -- live, npm-sandbox, plugin, or registry?"

Mode: live

Validates a workspace that is already wired (npm/pnpm surface). No build, no temp dir, no cleanup.

Run against the workspace: gaia doctor then gaia status, then the wire-up checklist below. This is the mode gaia-release Layer 1 and Layer 3 call after installing into the target (via gaia dev --workspace <TARGET>, the one-command install).

Mode: npm-sandbox

Validates the npm surface of exactly what a registry publish would ship -- pack, install into a clean sandbox, run the harness, clean up. No accumulated workspace state.

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.
