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 A, and why

onboarding-express 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 7d 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.

Onboarding Express

AI-guided architectural tour of any codebase for a new developer. Powered by Graph-It-Live — extracts entry points, business logic, and the most complex module in one structured pass.

CLI and Capability Discovery

Prefer the Graph-It CLI. At the first activation of any Graph-It skill in a session, check graph-it --version when the CLI and terminal are available; use only its existing newer-version notice and do not poll npm. Share discovery, version, and update decisions across Graph-It skills for the session. Run graph-it tool --list once, consult graph-it --help or command help as needed, and refresh only when the CLI/version, server, or workspace changes or a requested tool is unknown. Examples are illustrative, not a fixed inventory. Do not install automatically. If the CLI is unavailable or unsuitable, use MCP only when the connected host advertises a structurally equivalent tool and its schema; otherwise explain the gap. graph-it tool <name> invokes analysis directly through CLI; graph-it serve starts MCP. CLI --format and MCP response_format are distinct.

If the CLI reports a newer version, interactive use requires explicit positive confirmation before running graph-it update; silence, timeout, refusal, non-TTY, or generic Agent mode is not consent. When automatic mode is explicitly enabled and pre-authorized, default the update decision to yes and run graph-it update without another prompt. After success, refresh the version and --list, invalidate cached capabilities, and advise that a running MCP server needs a host-authorized restart. On failure, keep using the existing CLI only if it remains usable; otherwise explain the failure and stop CLI analysis. Warn briefly and do not retry in a loop.

Choose the Workspace Root

Graph-It-Live analyzes one workspace root and skips every import that resolves outside it. Without --workspace, the CLI uses the nearest directory holding package.json or tsconfig.json; an explicit graph-it -w <dir> is used exactly as given. The index and cache (.graph-it/) are created in the chosen root.
