missing-name

missing-name is a skill for Claude Code, Codex from meteor/agent-skills. It costs 14 tokens per session (60 once invoked), scanned A, original, MIT.

A deliberately incomplete fixture for testing a validator. It leaves out the required name field so the validator can check that invalid input is rejected.

In plain words
What is it for?
Use it in validator unit tests to verify that input without a name produces the expected E_SCHEMA error.
Why use it?
It provides a small test case for confirming that the validator catches a missing required field.

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

missing-name 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 3d 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.

What it actually says

No name field

Validator should reject this with E_SCHEMA.

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.
