standard-skill-test

standard-skill-test is a skill for Claude Code, Codex from crystian/skill-map. It costs 12 tokens per session (62 once invoked), scanned A, original, MIT.

A skill for running tests based on an open, vendor-neutral standard. Agent Skills are reusable instruction packages that different coding agents can read.

In plain words
What is it for?
Use it to run the standard skill test and classify the result for OpenCode or other agents that support Agent Skills.
Why use it?
It helps check whether an agent can use the shared skill format rather than relying on one tool vendor's private format.

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

standard-skill-test 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 4d 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

Open-standard skill

Lives under the vendor-neutral .agents/skills/. Read by OpenCode (and every other Agent Skills adopter). Classifies as opencode/skill under this lens.

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.
