setup-openlinker-cli

Instructions for checking or explicitly installing the exact OpenLinker command-line tool version required by a plugin.

In plain words
What is it for?
They help find a compatible CLI, report its version and capabilities, or install the pinned release with checksum verification.
Why use it?
They prevent incompatible or floating-version installations and require the tool to be verified before changes are made.

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.

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

setup-openlinker-cli 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 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.

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

Set Up the OpenLinker CLI

Use the Plugin's deterministic resolver and installer. Do not implement an alternate downloader, install a floating latest, or modify a project file.

Verify First

Resolve the package root from PLUGIN_ROOT, then CLAUDE_PLUGIN_ROOT, or the installed Skill location. Run scripts/resolve-openlinker-cli from that root. It checks, in order, OPENLINKER_CLI_BIN, PATH, and the Plugin data directory, then validates context JSON, surface version, and requested capabilities.

If a compatible CLI is found, report its path, version, and capabilities and stop. Never print OPENLINKER_USER_TOKEN or other environment values.

Install Only with Explicit Intent

Running this Skill or /openlinker-setup is explicit installation intent. Before invoking the installer, show:

  • the pinned CLI version from cli-lock.json;
  • the GitHub release origin;
  • the platform/architecture;
  • the Plugin data destination.

Then run scripts/install-openlinker-cli from that root on POSIX systems or scripts/install-openlinker-cli.ps1 on Windows. The installer must select an exact entry from cli-lock.json, download the archive and adjacent checksum, verify SHA-256, reject symlink destinations, extract only the expected executable, and install atomically into Plugin data. A failed check must leave the previous CLI untouched.

Honor standard HTTP/HTTPS proxy configuration. Do not disable TLS validation, follow a private-network redirect, use credentials from prompts, or fall back to an unverified binary.

After installation, run the resolver again and report only non-sensitive version and capability information. If installation cannot complete, provide the exact failure and the manual fixed-release installation option; do not silently switch the Plugin to remote MCP.

Changes

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.
