toolhive-studio: Skill for Claude Code

.claude/skills/deep-links/SKILL.md

deep-links is a skill for Claude Code from stacklok/toolhive-studio. It costs 53 tokens per session (1,468 once invoked), scanned A, original, Apache-2.0.

A guide to deep links, special links that open a particular screen or action inside ToolHive Studio, a desktop application.

In plain words
What is it for?
Use it to implement or troubleshoot navigation links, install actions, and registry detail screens. It also covers the link format, intents, internal communication, and platform packaging.
Why use it?
It explains how browsers, terminals, and other applications can navigate ToolHive Studio through the toolhive-gui:// link format. This helps when adding or debugging links between applications.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

This is stacklok/toolhive-studio's own configuration. It tells Claude Code how to work on toolhive-studio itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything toolhive-studio configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./node_modules/.bin/electron . "toolhive-gui://v1/my-new-intent?someParam=value".

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

deep-links 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Deep links allow external systems (browsers, terminals, other apps) to trigger navigation inside ToolHive Desktop via the toolhive-gui:// custom protocol.

About this document: Much of the content in the reference docs is the result of research into how other Electron apps implement deep links. Some design decisions are implemented; others describe the intended direction but are not yet in the codebase. The base skill reflects the current implementation. The reference docs reflect the research and design intent — read them with that in mind, and update them when relevant implementation decisions change.


URL Schema

toolhive-gui://v1/<intent>[?<query>]

Examples:

  • toolhive-gui://v1/open-registry-server-detail?serverName=fetch — open a registry server detail page
  • toolhive-gui://v1/open-registry-server-install?serverName=fetch — open the registry server detail page and auto-open the install dialog
  • toolhive-gui://v1/open-registry-skill-detail?namespace=io.github.stacklok&skillName=skill-creator — open a registry skill detail page
  • toolhive-gui://v1/open-registry-skill-install?namespace=io.github.stacklok&skillName=skill-creator&version=v1.0.0 — open the skill detail page and auto-open the install dialog with the reference (and optional ?version tag) prefilled. Tag-only — OCI digests (sha256:…) are intentionally not supported because safeIdentifier rejects colons; users wanting digest pinning can paste it into the dialog directly.

The v1 segment is the version. The intent is a kebab-case action name. Query params carry intent-specific data.


Current Implementation

Key Files

File Role
common/deep-links.ts Single source of truth. All deep link definitions: intent name, Zod param schema, navigation target.
main/src/deep-links/parse.ts Parses and validates a raw URL string using the schemas from common/deep-links.ts.
main/src/deep-links/index.ts Entry point: extracts URL from argv (Windows/Linux), waits for window ready, dispatches via IPC.
main/src/deep-links/squirrel.ts Squirrel.Windows-specific protocol registration.

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.
