SkillSpector: 2 findings, up to medium
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 →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00156 | $0.02147 |
| Opus 5 | $0.00078 | $0.01073 |
| Sonnet 5 | $0.00031 | $0.00429 |
| Haiku 4.5 | $0.00016 | $0.00215 |
Grade A, and why
launch-shadcn-registry scanned grade A 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 11d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
compatibility: Requires network access, curl, gh (GitHub CLI), and git. User must be authenticated with gh for PR creation. How it starts
The opening of the file, as written. The whole thing — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Launch shadcn Registry
Orchestrate listing and announcing a custom shadcn/ui registry across official and community directories, then draft platform-specific social posts.
Before You Start
Confirm the user wants a full launch or a subset (e.g. official directory only, or social drafts only). Default to the full workflow unless they narrow scope.
Collect or infer a registry profile. If missing fields, ask before generating artifacts. Use templates/registry-profile.example.json as the shape; validate against templates/registry-profile.schema.json.
Required profile fields:
| Field | Purpose |
|---|---|
scope |
Registry scope, e.g. @ogimagecn |
name |
Display name |
homepage |
Marketing/docs URL |
registryBaseUrl |
Base URL for JSON files (no trailing slash) |
componentUrlPattern |
URL pattern with {name} placeholder, e.g. https://example.com/r/{name}.json |
description |
One sentence (≤160 chars) for directories |
descriptionLong |
2–3 sentences for awesome lists and social |
githubUrl |
Source repo |
githubUsername |
For avatar URLs and filenames |
distribution |
open-source or premium |
categories |
Tags for shadcntemplates / awesome lists |
installExample |
e.g. npx shadcn@latest add @scope/component-name |
logo |
Inline SVG string for official directory (optional but recommended) |
registryIndexPath |
Path to registry index relative to registryBaseUrl, defaults to /registry.json (optional) |
sampleComponents |
Array of component slugs to validate during preflight, e.g. ["og-image"] (optional) |
features |
Bullet points for shadcntemplates and social posts (optional) |

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.

launch-shadcn-registry is a skill published in the GitHub repository shadcn-labs/agentcn (458 stars, last pushed 18d ago), licensed MIT.
