name-check

name-check is a skill for Claude Code from uwuclxdy/agenticat. It costs 30 tokens per session (786 once invoked), scanned A, original, MIT.

A naming assistant for software projects, packages, and related domains. It suggests names and checks whether they are already used on major package registries, GitHub, and the web.

In plain words
What is it for?
Use it to brainstorm names, compare descriptive and brand-style options, check package and domain availability, and flag possible name collisions before a rename or launch.
Why use it?
It reduces the chance of choosing a name that is unavailable, confusingly similar to another project, or costly to change after release.

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

name-check 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.

The scan reads SKILL.md. This mod also ships 1 executable file (name-check.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Name Check

Procedure

  1. Scope first (before a rename or release). Establish from context (ask if unsure):
    • what the thing does, in one line
    • which registries matter: crates.io, AUR, PyPI, npm, GitHub, KDE store, domain... Check only relevant registries depending on the project.
    • rename cost: unpublished (cheap, anything goes) vs already public (flag every rename consequence)
  2. Generate 10-30 candidates. Brainstorm and balance three axes:
    • explicit: name states the function (kate-markdown-preview over katdown)
    • brandable: short, lowercase, occasionally punny (flit, nook, perch)
    • user-fit: closest to the user's stated direction Mark each candidate with which axis it leans toward. Reserve companion names too when relevant (flit + flitd + flit-mcp).
  3. Check availability in parallel. Fan out searches (web + registry pages) per candidate:
    • exact match on each relevant registry
    • general web collision: existing project, product, or company with the same name in the same space
    • near-collisions worth flagging (one-letter-off popular project, trademark-adjacent)
  4. Report as a table with these columns:
candidate web collision note

free / taken (link) / near: <what> per cell. End with one recommendation and why.

Helper

name-check.ts (same dir as the skill, requires bun) runs the deterministic registry axis in one pass to spare you the manual fetching:

bun name-check.ts <name> [<name>...] [--table] [--registry npm,crates,...] [--tld com,io]

  • compact JSON by default; --table for a quick scan, --list for registry ids.
  • supports npm, PyPI, crates.io, RubyGems, Hackage, Go, Docker (library), Homebrew, AUR, NuGet, GitHub, plus domain availability (RDAP, DNS-confirmed on a 404).
  • domain checks run only when --registry is unset or explicitly includes domain (e.g. --registry npm,domain). The flag is not additive by default for domains.
  • does not do web collision. still run that axis via WebSearch (same-space products, companies, trademarks) and fold both into the report table. Not a legal trademark search either (see Rules).
  • registry read-only.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

name-check is a skill published in the GitHub repository uwuclxdy/agenticat (5 stars, last pushed yesterday), licensed MIT. It adds 30 tokens to every session and 786 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
