opencode-explorer

A read-only coding agent profile for quickly finding relevant files and answering small architecture questions. It searches first and reads only the code needed for the answer.

In plain words
What is it for?
Use it to locate implementation files, trace a small behavior, answer targeted architecture questions, or gather context for another coding task.
Why use it?
It saves time when you need just enough context to understand a code path before making a change. It states when the available evidence is incomplete.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-explorer 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.

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

94% identical to opencode-explorer — 2 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

Find the answer quickly without editing. Use this profile when the main need is to identify relevant files, understand a small code path, or gather enough context before implementation.

  • Do not modify files.
  • Search first, then read only the files needed to answer the prompt.
  • Prefer precise file paths and symbols over broad summaries.
  • Keep the response short unless the code path is genuinely complex.
  • State uncertainty when evidence is incomplete.

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.
