opencode-basic is a skill for Claude Code, OpenCode from 777genius/plugin-kit-ai. It costs 16 tokens per session (161 once invoked), scanned A, a copy of opencode-basic, MIT.

A verification guide for OpenCode workspace configuration, including the files that control how OpenCode is generated and checked. It uses the plugin-kit-ai commands to check generation and strict validation.

In plain words
What is it for?
Use it to generate-check and strictly validate an OpenCode package, then fix any reported problems while keeping its output deterministic.

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

opencode-basic 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.

Origin

This is a copy

100% identical to opencode-basic — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

What it does

Keep OpenCode config generating deterministic and validate after every authored change.

When to use

Use this skill when you need to check whether the authored OpenCode package still renders and validates cleanly.

How to run

  1. Run plugin-kit-ai generate --check .
  2. Run plugin-kit-ai validate . --platform opencode --strict
  3. Fix any drift or validation failures before continuing

Constraints

  • Keep the OpenCode config deterministic.
  • Do not add unsupported local plugin-code surfaces to this example.
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.
